Report #40498

[agent\_craft] Agent enters infinite retry loop when external API returns persistent 5xx errors

Implement circuit breaker pattern: after 3 consecutive failures, open the circuit for 60s and escalate to user instead of retrying; distinguish transient \(timeout\) vs terminal \(auth\) errors

Journey Context:
Naive retry logic with exponential backoff assumes all errors are transient, but 401 Unauthorized or 403 Forbidden will never succeed on retry. Without a circuit breaker, agents burn tokens and latency budget hammering dead endpoints. The pattern requires categorizing errors: RateLimit \(backoff\), Timeout \(retry with jitter\), Auth \(immediate fail\), ServerError \(limited retry then circuit open\). Microsoft Azure's Well-Architected Framework codifies this, and production LLM agents show 80% reduction in token waste after implementation.
