Report #84092

[agent\_craft] Agent enters infinite loop retrying failed tool calls with identical parameters

Implement exponential backoff with parameter mutation: parse error type \(transient vs permanent\), vary parameters on retry \(e.g., reduce batch size on timeout\), hard stop after 3 attempts with escalation to user

Journey Context:
Simple retry loops on API 429s or syntax errors waste tokens. Distinguish between service unavailable \(backoff helps\) vs invalid argument \(backoff hurts\). For coding tools \(compilers, linters\), mutation means adjusting the input code based on error message, not just resubmitting.
