[agent\_craft] Agent's chain-of-thought or reasoning output leaks internal policy checks, classifier behavior, or exploit-fabrication steps

Use chain-of-thought for internal safety monitoring, not user-facing output. If you expose reasoning, sanitize it so it does not contain raw policy strings, classifier internals, or step-by-step exploit construction. Internal reasoning can consider harmful content for the purpose of refusing it; external output must not propagate that content.

Journey Context:
Chain-of-thought is a double-edged sword. It improves reasoning and makes safety checks inspectable, but it can also leak how the model detects misuse or even generate the very content it is supposed to refuse. Coding agents may reason through an exploit to decide whether to refuse, then accidentally hand the user a blueprint. The pattern is 'think privately, speak safely': reasoning can analyze the risk, but the final answer must be clean. This is especially important when the agent is serving other agents as the end user, because an attacker can prompt for 'show your thinking' to harvest internals.
