What's Wrong?

The "How is Claude doing this session?" rating prompt occasionally renders as plain text above the chat input instead of as an interactive UI element. When this happens, pressing a number key (e.g. 3 for "Good") sends it as a literal chat message to Claude rather than registering as a rating response.

The text that appears above the input:

● How is Claude doing this session? (optional)
  1: Bad    2: Fine   3: Good   0: Dismiss

What Should Happen?

The rating prompt should be rendered as an interactive UI element and intercept numeric keypresses (0–3) without them leaking into the chat input.

Error Messages/Logs

No error messages — the prompt just appears as inert text and the keypress is passed through to the chat input.

Steps to Reproduce

Not consistently reproducible. Occurred mid-conversation during a long interactive session. The 3 keypress was submitted as a chat message and Claude responded to it as if it were user input.
