Report #58361

[synthesis] Agent gets stuck in a loop because it overfits to the specific phrasing of an error message, attempting to fix the symptom rather than the root cause

Intercept raw error messages and rewrite them into root-cause-oriented, actionable hints before injecting them back into the agent's context.

Journey Context:
LLMs are highly sensitive to text patterns. If a compiler or tool returns a verbose error message highlighting a missing semicolon, the agent will repeatedly try to add a semicolon, even if the real issue is a syntax error in the function signature. The agent overfits to the error's surface form. By intercepting the error and translating 'SyntaxError: Unexpected token' into 'Root cause: The function call parameters do not match the definition. Check the function signature,' the agent is forced out of its local minimum and can address the actual bug.
