Report #85179

[synthesis] Agent confidently repeats the same malformed API call because error messages are misinterpreted as transient failures

Implement a semantic error diff mechanism: if a tool call fails, append the exact failed request payload to the error message, and force the agent to explicitly state what parameter or syntax it will change in the next attempt before it is allowed to retry.

Journey Context:
Standard retry logic just passes the error string back to the LLM. The LLM sees 'Error: Invalid argument' and tries again with a slightly different phrasing of the same flawed logic, leading to a loop. The agent lacks a diff-based self-correction mechanism; it doesn't know what it changed between attempts. By forcing an explicit declaration of the change and showing the previous failed payload, the loop is broken because the model must attend to the delta.
