Report #36332

[agent\_craft] Agent stuck in infinite retry loops on persistent tool failures \(e.g., compilation errors\)

Implement exponential backoff with max retry cap \(2-3 attempts\), then escalate to user or switch strategy; classify errors as transient \(network timeout\) vs deterministic \(syntax error\) and never retry deterministic errors with identical parameters.

Journey Context:
Agents often implement naive 'while error: retry' loops. But deterministic errors \(syntax errors, permission denied\) won't fix themselves. Need error classification \(transient vs deterministic\) and escalation. Exponential backoff with jitter prevents thundering herd on recovering services. Tradeoff: user interruption vs wasted tokens and time.
