Report #84258

[synthesis] Agent fails to detect model reasoning failures because confidence levels remain high and output structure varies

Look for Claude's signature 'Wait, let me re-evaluate' or 'I apologize' strings for self-correction. For GPT-4o, implement an external verification step \(e.g., Python REPL\) as it confidently outputs wrong math. For Gemini, check for generic refusal phrases.

Journey Context:
Models do not output a reliable uncertainty score. GPT-4o's failure signature is high-confidence plausible errors. Claude's signature is verbose self-doubt and mid-stream corrections. Gemini's is a generic fallback. An agent cannot use a single heuristic to detect failure; it must parse model-specific failure strings or, for GPT-4o, rely entirely on external tool validation rather than textual confidence.
