Anthropic returns HTTP 400 with "You're out of extra usage. Add more at claude.ai/settings/usage and keep going." when the account's extra-usage allowance is depleted. The existing _BILLING_PATTERNS list did not include this wording, so classify_api_error fell through to generic format_error — non-retryable and should_fallback=False — causing the agent to abort instead of engaging the configured fallback chain. Add the pattern and a regression test covering the exact Anthropic body.

Anthropic returns HTTP 400 with
"You're out of extra usage. Add more at claude.ai/settings/usage and keep going."when a user's extra-usage allowance is depleted. This wording is not in_BILLING_PATTERNSinagent/error_classifier.py, soclassify_api_errorfalls through_classify_400to the generic format_error path (retryable=False,should_fallback=False). The agent aborts instead of engaging the configured fallback chain (fallback_providers/fallback_model).Fix: add
"out of extra usage"to_BILLING_PATTERNS. Now classified asFailoverReason.billing→should_fallback=True, matching how other providers' billing-exhaustion messages are handled.Repro
Primary Anthropic model with depleted extra usage + Gemini fallback configured:
After the fix the same error triggers the fallback chain and the agent continues on the fallback provider.
