[gotcha] When does showing AI chain-of-thought reasoning hurt UX instead of building trust

Never expose raw chain-of-thought or tool-call output to end users. Translate reasoning into human-readable summaries \('I checked 3 sources' not 'Tool call: search\(query=...\) returned 3 results'\). Use progressive disclosure: default to a one-line reasoning summary, expandable on click for details. Only show reasoning when the user can act on it to change the outcome.

Journey Context:
The instinct is 'transparency builds trust,' but raw chain-of-thought is written for the model's internal process, not human consumption. It contains tool-call syntax, system prompt leaks, hedging loops \('Let me think about whether this is appropriate...'\), and reasoning dead ends that are meaningless or actively alarming to users. Users see the AI 'deciding whether to refuse' and lose confidence. They see JSON function calls and think the system is broken. They see the AI consider a wrong path before self-correcting and fixate on the wrong path. The fix is to never show raw reasoning — always translate it into user-facing language. Progressive disclosure lets power users dig deeper without overwhelming casual users. The key test: if seeing the reasoning doesn't help the user make a better decision or take a different action, hide it.
