Report #50083

[synthesis] Agent enters infinite or compounding retry loops for failed tool calls because error messages accumulate in context window, eventually exhausting token limit or confusing the repair attempt

Implement exponential backoff with context truncation: before each retry, truncate the context to remove the failed attempt's error message and reasoning, keeping only the original intent and the error summary; hard limit retries to 3 attempts with escalating delay

Journey Context:
OpenAI function calling docs show retry logic, RFC 7230 shows persistent connections. Synthesis reveals the 'blindness': agents don't reset context between retries, so error messages from attempt 1 contaminate attempt 2's reasoning. Single sources discuss 'retry with backoff' or 'context window management' separately, but not the interaction where error messages compound. Example: attempt 1 fails with 'Invalid user\_id', agent tries to fix, attempt 2 fails with 'User not found', but context now contains both errors, agent conflates them and attempts 3-5 spiral into nonsense or token limit. Common mistake: catching exception and re-prompting with 'try again' without clearing the failed reasoning trace. Alternatives: full state reset \(loses intent\), or infinite retry \(expensive\). Fix requires 'surgical truncation': keep the goal, keep the error type, discard the failed reasoning chain.
