[synthesis] Agent interprets API rate limit errors as logical failures and escalates retry attempts with modified payloads

Map HTTP 429 explicitly in tool schemas as a 'wait' state, distinct from 4xx logical errors. Implement exponential backoff at the orchestrator level, and prevent the agent from altering the request payload during a 429 retry.

Journey Context:
When an agent hits an API rate limit \(HTTP 429\), it often misinterprets the error as 'my request was bad.' It then attempts to fix the payload, generating a new, slightly different request. This compounds the rate limit issue and creates a retry storm. Worse, the modified payloads might eventually succeed for the wrong reasons, leaving the system in an inconsistent state. The synthesis is that LLMs conflate 'request rejected' with 'request incorrect,' and their default reaction to failure is mutation. Standard error handling must intercept 429s at the infrastructure layer to prevent the LLM from entering a mutating retry loop.
