Report #41966

[frontier] Cascading failures when external APIs \(search, code exec\) lag or fail during agent execution freeze the entire orchestration

Implement circuit breakers \(closed/open/half-open states\) around LLM tool invocations with exponential backoff and fallback to cached or degraded modes. Monitor error rates, not just latency, with per-tool failure budgets.

Journey Context:
Agents without circuit breakers retry infinitely on failure, exhausting resources and hanging the orchestration. Circuit breakers fail fast when error thresholds breach, allowing graceful degradation \(e.g., 'search is down, using memory only'\). This prevents one slow tool from freezing the entire agent graph, applying microservices resilience patterns to cognitive architectures.
