[agent\_craft] Chain-of-Thought reasoning leaks internal logic or generates plausible but unfaithful explanations

Use 'hidden CoT' where reasoning is generated in a separate block that is stripped before user delivery, or omit CoT for straightforward tasks; never expose raw CoT to users in security-sensitive applications.

Journey Context:
While CoT improves reasoning on complex math, research shows models generate plausible-sounding rationales that don't actually reflect their internal computation \(unfaithful CoT\). This creates false user confidence and leaks implementation details if the CoT references internal tools or schemas. Furthermore, exposed CoT is vulnerable to prompt injection attacks targeting the reasoning process. The correct pattern is to generate reasoning in a block or separate API call, parse it for debugging, but deliver only the final answer to the user. For simple tasks where the model has high baseline accuracy, CoT adds token overhead without benefit.
