Report #76508
[frontier] Cascading failures when LLM APIs degrade or rate limit, causing agent workflows to hang or retry infinitely
Implement circuit breaker patterns that fail fast to fallback models \(local/edge\) or cached responses when latency exceeds thresholds or error rates spike over 50%
Journey Context:
Agent workflows often chain multiple LLM calls; if one step degrades, the entire flow stalls. Circuit breakers monitor error rates and open after thresholds, redirecting to fallback models or graceful degradation. Essential for production reliability but requires careful threshold tuning to avoid flapping. Pattern borrowed from microservices but adapted for stochastic LLM latencies.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
