📝 WalkthroughWalkthroughThe provider factory now supports per-provider built-in circuit-breaker rules. Kimicode defines quota-based defaults. Admin upserts normalize empty rules to nil so defaults apply. Tests cover precedence, matching, breaker state, reset behavior, and upstream suppression. ChangesCircuit-breaker defaults

client.Do call to count requests received by the upstream handler, then require
that the count is two after the second attempt. Keep the existing error
assertion, but use the handler-call count to verify ResetBreaker cleared the
breaker state and allowed the request upstream.
- Around line 120-122: Update the test’s post-scan assertion around found so
every case verifies that found equals tt.wantOK, including positive cases;
retain the existing no-match diagnostic if useful but ensure successful usage
limit and quota matches cannot pass with found still false.

- Line 31: Update the fallback pattern in llmclient.quotaTripTTL to match “usage
limit” or the pinned “quota exceeded” phrase, removing the bare quota match. Add
a near-miss fixture covering a non-limit 403 message containing quota and verify
it does not trigger RecordQuotaTrip.

All three are test/stability-only, no behavior change to the trip semantics otherwise. Unless you object, I'll proceed with these as one commit.

internal/providers/kimicode/trip_defaults_test.go (1)
141-184: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winAssert the resolved rules in the two precedence subtests.
"no config trip_on gets defaults" and "explicit empty list disables defaults" assert only that
factory.Createreturns no error. Both subtests pass even if the factory applies the opposite precedence. The nil case is covered end-to-end byTestFactoryPath_E2E, but the empty-list case has no behavioral coverage anywhere in this file, so a regression that applies defaults over an explicit empty list stays undetected.Drive the empty-list subtest through the provider and count upstream calls, as the other e2e tests do.
Based on learnings: a test that asserts only a non-failure outcome can pass even when the branch under test was never exercised.

Included review availability: Your plan provides up to 1 included review per hour; 0 remain after this review.
Ship built-in circuit-breaker trip rules for the kimicode provider type
only. Defaults apply when config-level circuit_breaker.trip_on is nil
(inherited from global); explicit trip_on (including empty list)
overrides or disables defaults.
Default rules:
weekly (7-day) usage limit → 4h TTL
5-hour usage limit → 30m TTL
usage limit|quota (catch-all) → 15m TTL
Regexes pin observed audit-log error bodies verbatim.
Changes:
- internal/providers/factory.go: add DefaultTripOn field to
Registration struct; store in factory; apply in Create() before
provider opts are built.
- internal/providers/kimicode/kimicode.go: wire DefaultTripOn.
- internal/providers/kimicode/trip_defaults.go: compiled defaults.
- internal/providers/kimicode/kimicode_test.go: 20 tests — compile,
match pinned bodies, non-match, factory resolution, e2e trip.
- assert rule-set match result after the scan loop so a broken rule fails positive cases - count upstream handler calls to prove reset lets traffic through - narrow catch-all rule to 'usage limit|quota exceeded' so non-limit 403s mentioning quota do not trip; add near-miss fixture
Finding 1: normalize empty trip_on to nil in admin upsert so factory defaults apply. The managed credential path has no explicit-disable concept — the dashboard always sends trip_on: [] when no rules are configured. Normalising [] to nil lets the factory apply its built-in defaults, the same path a YAML-declared provider gets when trip_on is absent. Added handler test pinning explicit [] -> nil with no error. Finding 2: added TestFactoryPath_E2E exercising Registration.DefaultTripOn -> ProviderFactory.Create -> provider -> llmclient end-to-end. Factory-applied defaults actually trip the breaker and second request fails fast with "circuit breaker is open". Finding 3: replaced three httptest.NewServer fakes with providertest.JSONServer(t, status, body) + Capture/Count(). Removed unused net/http/httptest and sync/atomic imports.
…efaults - TestFactoryPath_E2E now sends requests through the factory-created provider itself instead of replicating defaults in a hand-built client - document the built-in trip rule defaults (inherit/replace/disable) in docs/providers/kimicode.mdx
…p name kimicode ships three named groups (1_weekly_limit, 2_five_hour_limit, 3_usage_limit); the numeric prefix is the evaluation priority, matching the named-map config shape so env overrides can target single rules, e.g. KIMICODE_CIRCUIT_BREAKER_TRIP_ON_1_WEEKLY_LIMIT_MATCH

TL;DR
PR #108 added per-provider circuit-breaker trip rules; without rules, no provider trips. This stacks built-in rules for the
kimicodeprovider type, covering the Kimi for Coding plan's weekly and 5-hour usage-limit messages (HTTP 403), so kimicode providers trip and fail over with zero configuration.Explicit
trip_onconfig overrides the defaults; an explicittrip_on: []disables tripping for that provider (no defaults applied). Z.ai is deliberately excluded: zai providers commonly run a custom base URL, so provider-type-level message defaults would be guesses.Files to review (start here):

trip_onin a kimicode provider's config replaces the defaults; explicittrip_on: []disables tripping for that provider; absent config inherits the defaults.kimicodetype ships defaults; every other provider type is unchanged (DefaultTripOnnil = no defaults).Tests
20 test cases: regex compilation + TTL presence, pinned-body match (5 variants incl. non-matching), Registration slice shape, factory resolution (nil -> defaults, empty -> disabled, non-empty -> config wins), e2e trip on weekly + 5-hour bodies, reset clears the trip window.
