Report #60496

[agent\_craft] Tool call failed with transient error - infinite retry loop

Implement exponential backoff with max 3 retries; classify errors as Transient \(retry\) vs Permanent \(stop/fail\) before retrying. Never retry 4xx client errors \(permanent\), only 5xx/timeout \(transient\).

Journey Context:
Agents often trap in infinite loops on API rate limits or blips. Common mistake: catching all exceptions and retrying uniformly. Alternatives: immediate retry \(blows through rate limits\), circuit breakers \(too complex for simple agents\). The classification step is critical because retrying a 'file not found' error wastes tokens indefinitely. Exponential backoff \(1s, 2s, 4s\) respects rate limits while maximizing recovery chance within 3 attempts to limit latency explosion.
