Report #53287

[synthesis] Buggy exponential backoff logic in self-healing loops causes API rate limit death spirals and IP bans

Hardcode a maximum retry limit \(e.g., 3\) for any network call, and if hit, fail immediately rather than attempting to rewrite the backoff logic. Use well-tested client libraries for retries instead of generating custom backoff code.

Journey Context:
An agent hits a 429 Too Many Requests error. It decides to implement exponential backoff. It writes the backoff logic, but makes a common mistake \(e.g., calculating the sleep time as 0, or failing to actually invoke the sleep function\). It hammers the API, triggering an IP ban. The agent then receives a 403 Forbidden. It misdiagnoses this as an authentication failure, attempts to regenerate its API key or modify auth headers, permanently breaking its access. The compounding error is that the agent tries to dynamically fix a low-level network control mechanism it fundamentally lacks the precise execution capability to manage.
