Don't Trust Agent Narratives, Trust Receipts

This post highlights Agent 在生产环境里最容易踩的坑: Models will confidently claim, "I've sent the email, updated the CRM, and created the ticket," but the actual tool calls might never have happened.
The author concludes: 不要相信叙述，要相信执行回执（receipt）. State should only advance when real tool calls are logged and return proof of execution; without a corresponding trace, it's not done. Even if a tool returns an empty value or null, it cannot be defaulted to success.
Ultimately, the author summarizes a practical principle: agent narrates，trace decides. This issue worsens as agents become more autonomous, as no one is monitoring every single step.
