Report #53195

[synthesis] Tool error recovery loops exhibit overcorrection, precise patching, or infinite loops depending on the model

Implement a retry counter to break Gemini loops and a diff-checker to prevent GPT-4o from altering unrelated parameters during error recovery.

Journey Context:
When a tool returns an error \(e.g., Invalid JSON\), agents often just feed the error back to the LLM. Claude precisely patches the error, GPT-4o overcorrects by rewriting the entire request \(changing unrelated parameters\), and Gemini gets stuck in a loop retrying the exact same failed payload. Native retry mechanisms are insufficient; the orchestrator must enforce behavioral constraints.
