Report #64317

[gotcha] AI response silently truncates at max tokens without UI indication

Check the finish\_reason in the API response. If it is length, append a UI indicator \(e.g., 'Output truncated, click to continue'\) and automatically prompt the LLM with 'Continue' on user click.

Journey Context:
Streaming text looks complete because the UI simply stops rendering. Users think the AI finished its thought, leading to incomplete code or half-baked advice. Developers forget to check the finish\_reason payload during streaming, assuming the stream ending naturally means the thought is complete.
