Report #90875

[frontier] Autonomous agents get stuck in infinite tool-call loops or retry storms during outages

Implement circuit breakers that detect repeated identical tool calls or error rates and force agent termination or human handoff

Journey Context:
Agents without circuit breakers will loop 'search -> no results -> search again' forever or retry failed APIs exponentially. The pattern is adapting microservices circuit breakers \(Resilience4j, Polly\) to agent loops: track call patterns, open the circuit after N identical calls or M consecutive errors, and trigger fallback behavior \(human escalation, simplified prompt\). This requires instrumentation of the agent's tool calls to detect loops \(e.g., Levenshtein similarity between arguments\). It's distinct from simple timeout because it detects semantic loops. This is critical for production agents with tool access.
