Numbered feedback prompts conflict with numbered user responses

[pentafive]

What's Wrong?

The feedback rating system prompts for numeric input (0-5 scale). When users respond to Claude's questions using numbered lists (e.g., "1. answer 2. question 3. task"), the input parser interprets leading numbers as feedback ratings instead of message content. This causes:

• Incorrect feedback being submitted
• User prompts being mangled or truncated
• Loss of intended message content

What Should Happen?

Numbered list responses should not be intercepted as feedback ratings. The feedback system should require explicit confirmation or use non-numeric input to avoid collision with common response formats.

Steps to Reproduce

1. Engage in a conversation where Claude asks a multi-part question
2. Wait for or trigger a feedback prompt (0-5 rating request)
3. Respond with a numbered list: "1. First answer 2. Second point 3. Additional context"
4. Observe that the leading number is captured as feedback rating
5. Notice the remaining text is either truncated or mishandled

Error Messages/Logs

No explicit error - the feedback is silently submitted with the wrong value and the user's actual response is corrupted.

Is this a regression?

Yes - this behavior has been observed in previous versions but the exact version is unknown.

Additional Information

This is a UX/input parsing issue where the feedback collection mechanism collides with common user input patterns. Numbered lists are a natural way to respond to multi-part questions, making this collision likely to occur frequently.
