) When an agent has multiple auth profiles configured, rate-limit or auth errors now trigger automatic retry with the next key in the rotation. Each key is tried at most once per message. - Add isAuthRotatableError() to error-classifier — detects rate-limit (429, quota exceeded, resource exhausted) and auth failures (401, unauthorized, invalid key) that may benefit from key rotation - Add resolveAuthProfileCount() to env-injection — returns the number of auth profiles configured for an agent - Add withAuthKeyRetry() orchestrator in auth-key-retry.ts — wraps execute callbacks with automatic retry on rotatable errors, capped at one attempt per configured key - Integrate withAuthKeyRetry in agent-runner-execution.ts — replaces direct resolveAuthEnv + bridge creation with retry-aware wrapper Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
