Report #64733

[frontier] Agents stuck in infinite loops or retry storms during tool failures

Implement circuit breaker pattern: track failure rates per tool/agent; after 3 consecutive failures, 'open' the circuit and fail fast for 60s; during open state, route to a fallback handler \(e.g., cached result or human handoff\); use 'half-open' state to test recovery before full restoration.

Journey Context:
Agents with retries can spiral when external APIs are down \(thundering herd\). Simple exponential backoff isn't enough because agents may be part of larger workflows. Circuit breakers \(from distributed systems theory\) prevent cascading failures. This is critical for production agents where 'trying until success' is not acceptable due to cost and latency. The pattern must track failures per specific tool\+agent combination, not globally, to avoid single-tool failures breaking the entire agent.
