Do not search for or infer other affected packages. +- **ESLint suppresses only rules configured as `error`.** A rule left at `warn` does not qualify, so adoption means `'error'`, never `'warn'`. +- Commit the generated suppression files.

Change that one rule from `'off'` to `'error'`. Change nothing else in the config. +2. For each selector-provided `packages` entry, change to its `workingDirectory` and capture the remaining violations in its `suppressionsFile`. **Always pass `--fix`**, so ESLint repairs anything it can instead of freezing those violations into the suppressions file: + + ```shell + mise exec -- pnpm exec eslint --fix --suppressions-location --suppress-rule . + ``` + + Omitting `--fix` here is a real error, not a style preference. It permanently suppresses violations the tooling could have fixed for free, and each one then costs a future pull request. + +3. Fix the violations in **one** remaining file by hand, then prune (see below). +4. Commit the config change, every generated suppressions file, and the one fixed file together. + +Adopting a rule holds all **new** code to it immediately. This immediate enforcement makes mode A worth one pull request even when only one file gets cleaned. + +### Mode B: burn down + +The rule is already `'error'` and has entries in a suppressions file. The script names the rule, the target file, the suppressions file it came from, and how many suppressions remain repo-wide. + +1. Fix the violations in that one file. Do not add inline disables. +2. Prune, from the `workingDirectory` the script reported: + + ```shell + mise exec -- pnpm exec eslint --prune-suppressions . + ``` + +3. Commit the shrunken suppressions file with the fix. + +Most rules that start in the off list address type safety, so mode B often requires TypeScript work. When the rule is one of the `no-unsafe-*` family, `no-non-null-assertion`, `no-unnecessary-type-assertion`, or `no-redundant-type-constituents`, read the [typescript skill](/.agents/skills/typescript/SKILL.md) first and prefer, in this order: + +1. give an untyped value a real type +2. narrow with a type guard +3. replace a non-null assertion with an explicit check +4. replace a type assertion with a discriminated union + +**Never silence a finding.** Do not add `as any`, `as unknown`, `!`, `@ts-expect-error`, or an `eslint-disable` comment. Removing a suppression by fixing the code is the whole task; removing one by hiding the violation means you must stop. + +Do not bulk-annotate return types. An explicit return type is worth adding only when it documents intent or catches a real widening bug. + +### Expected lint failure after fixing + +Once you fix a suppressed violation, ESLint exits **non-zero** with: + +``` +There are suppressions left that do not occur anymore. Consider re-running the command with `--prune-suppressions`. +``` + +This is success, not failure. It means your fix worked and the stale entry is still on disk. Resolve it by pruning. Do **not** revert your fix, do not re-run `--suppress-rule` to make the message go away, and do not add `--pass-on-unpruned-suppressions`, which only hides the condition and leaves the ratchet slipping backwards. + +**Done when**: the rule's suppression count strictly decreases, no stale suppressions remain, the file's public API is byte-identical, `pnpm run lint` passes with no new inline disables, and `pnpm run test` and `pnpm run test:types` pass. + + + +## Task: bug + +Fix **one** behavioral bug in one module. + +Use **quarantined tests** as candidates: an unconditional `it.skip`, `test.skip`, `.todo`, or `.fails` in a test file. Each test describes behavior that should work and does not, which makes it a good unattended task. The repository already contains the acceptance criterion, so you are not inventing scope. + +The script names the target as `:`. + +`.skipIf(...)` is a capability guard, not a bug. The script excludes it. Do not change those tests. + +Do not invent bugs. If the script finds no quarantined test, it moves to another task, so this task always includes a target. Never fix something you merely find suspicious while working on another task. + +### Procedure + +1. **Confirm the failure first.** Un-skip the test and run it. It must fail. +2. If it passes immediately, the bug is already fixed. That is still a valid pull request: remove the `.skip` and say so. Stop there. +3. If you cannot make it fail, the quarantine is not reproducible. Re-apply the skip, stop, and report what you tried. +4. Otherwise make the smallest change that turns the test green. +5. Do not refactor surrounding code, do not fix adjacent issues, do not tidy imports. +6. Do not weaken the test to make it pass. If you change an assertion to match broken behavior, stop. + +The script ranks quarantined **visual** tests last because you cannot update visual baselines. If the script selects one and the fix needs a new baseline, stop, and report it for a human. + +**Done when**: the test fails before the fix and passes after, you do not change its assertions, you change no other test, and the full project CI passes. + +## Verification + +Before opening the pull request, from the target project directory: + +```shell +mise exec -- pnpm run lint +mise exec -- pnpm run test +mise exec -- pnpm run test:types +``` + +For component changes also run `mise exec -- pnpm run test:axe` and `mise exec -- pnpm run test:ssr`. Do not update visual baselines. If a visual test fails, your change changed behavior: stop. + +Then self-review with the [code-review skill](/.agents/skills/code-review/SKILL.md) and fix anything it flags. + +## Statelessness + +This skill keeps no memory between runs. It writes no journal, no ledger, and no record of what it has already done. Every selection is a pure function of the working tree plus the remote's branches. + +That works because **the fix removes the candidate**: + +| Task | Why selection stops | +| ----------- | --------------------------------------------------------------- | +| lint mode A | the adopted rule leaves the off list | +| lint mode B | the pruned entry no longer exists in `eslint-suppressions.json` | +| bug | the un-skipped test is no longer quarantined | +| coverage | the file rises past the 90% threshold | + +Do not create state to compensate. Do not add a tracking file, do not write progress into a comment, and do not leave a marker for the next run to find. If you believe you need memory to avoid repeating work, you have misread the task: finish the target instead. + +The selector can legitimately choose a coverage target again when the previous fix improved the file without lifting it past the threshold. A second selection means the system works as intended. If the selector chooses the file a third time without any improvement, the target has a problem; stop and report rather than trying again. + +## Commit and Pull Request Contract + +Branch name: + +``` +upkeep// +``` + +The `upkeep/` prefix is load-bearing. The next run lists unmerged `upkeep/*` branches on the remote to detect work in flight, so a branch named anything else defeats the one-at-a-time guardrail. The rest of the name is for humans; make it describe the target. + +Commit messages must follow `commitlint.config.js`: + +- type is `fix` for the bug task, `chore` for everything else +- include a scope. Use the project directory name under `projects/`, except use `internals` for anything under `projects/internals/` and `docs` for `projects/site`. `commitlint.config.js` holds the authoritative list; if your target does not map to one of its values, use `internals`. +- subject is lower case, no trailing period, 100 characters max +- include a `Signed-off-by:` trailer + +Example: + +``` +chore(core): cover disabled state branches in badge + +Adds unit tests for the two uncovered branches in badge.ts, +raising line coverage from 84% to 96%.
