Report #55702

[frontier] Cascading failures in multi-agent systems when downstream agents hallucinate or timeout

Implement circuit-breaker patterns in the orchestration layer that monitor agent health and automatically fail-over to degraded modes or backup agents

Journey Context:
Agents calling agents creates deep dependency chains. When a specialist agent starts hallucinating \(e.g., generating invalid SQL repeatedly\), naive systems keep retrying, burning tokens and latency. The production solution borrows from microservices: each agent invocation passes through a circuit-breaker proxy that tracks error rates and latency. When thresholds breach, the breaker opens and routes to a fallback \(simpler prompt, cached response, or human escalation\). This prevents cascade failures in critical paths.
