📝 WalkthroughWalkthroughClaude Code Auto Mode classifier requests now support explicit classifier models, provider affinity, and ordered fallbacks. Pattern routing ignores disabled providers and selects enabled Anthropic-compatible adapters for unmatched Claude model patterns. ChangesClaude classifier routing
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟠 High · up to Auto Mode can still route classifier requests to a disabled or incompatible provider and skip configured fallbacks, causing classifier failures that may lock tool execution. Merge should wait until provider availability is checked and fallback behavior is covered. Sequence Diagram(s)sequenceDiagram

Do not stop at an unavailable classifier affinity route.
resolveInboundModel returns an affinity-qualified route whenever cc.model has a provider prefix. It never reaches classifierFallbacks if that provider is disabled or uses an incompatible adapter. The disabled-provider filter in src/router.ts applies only while routing bare known model IDs. A qualified route bypasses that recovery path. This violates the configured fallback contract and can make Auto Mode fail instead of using its next compatible classifier route.
Move candidate evaluation to a layer that has both OcxClaudeCodeConfig and OcxConfig. Preserve modelMap precedence. Validate affinity and fallback candidates against enabled Anthropic-compatible providers. Return a classifier-specific error after all candidates fail. Add regressions for a disabled affinity provider with an enabled fallback, and for no compatible provider.

Reviewed as part of a bug-PR landing pass. Holding this one: the direction is right, but the implementation changes a routing/privacy boundary in a way that needs a design decision first, not just an approval. Two independent reviews reached the same conclusion from separate reads of the diff. The affinity fix does not cover the reported case. The router fallback picks a provider arbitrarily. src/router.ts:699-705 sends every bare
Two smaller things. The classifier detector What would unblock it: resolve affinity from the live routed model rather than static config; require an explicit provider binding (or a catalog match) before crossing to another Anthropic-adapter provider instead of taking the first enabled one; make For context: CI here is green but shows only policy/labeling checks, no exact-head test or typecheck job, so the test claims in the description are author attestations rather than CI evidence. |

Triage note (2026-08-15, maintainer): keeping as draft per the existing design hold. The Auto Mode classifier defect is real and unfixed on dev, but this implementation can silently move classifier traffic across providers (static config instead of live routed state, first-non-empty fallback, no model-support validation) — that crosses privacy, billing, and credential-routing boundaries. The design requirements from the earlier review stand: live routed state, explicit or catalog-validated provider crossing, actually-attempted fallbacks, narrowed classifier detection. |
