Report #29528

[synthesis] Same ambiguous request causes Claude to ask a clarifying question and stall the agent loop while GPT-4o assumes intent and proceeds with potentially wrong action

For Claude in autonomous loops, add 'Do not ask clarifying questions. Make your best judgment and proceed.' to the system prompt. For GPT-4o, add 'If the request is ambiguous, state your assumption explicitly before proceeding.' For cross-model, implement both instructions and detect questions in the response \(text ending with '?' and no tool call\) to either auto-resolve or escalate to human.

Journey Context:
This is a fundamental behavioral fingerprint difference. Claude is trained to be helpful by seeking clarity when intent is ambiguous; GPT-4o is trained to be helpful by taking action. In an autonomous agent loop, Claude's clarifying questions are catastrophic — the agent stalls waiting for user input that never comes in a headless execution. GPT-4o's assumption-based approach keeps the agent moving but can compound errors silently. The fix depends on risk profile: for high-stakes operations such as production deployments or destructive actions, prefer Claude's caution and wire clarifying questions to a human-in-the-loop. For low-stakes high-throughput tasks such as batch processing or exploration, suppress Claude's questions and add assumption-logging to GPT-4o.
