What's Wrong?

[BUG] Infinite loop on "/rate-limit-options" after reaching the daily limit

Description
When the daily limit is reached, Claude Code displays the "/rate-limit-options" message in a loop (30+ consecutive times), with no way to interrupt the process or send a new prompt.

Observed behavior

1. The daily limit is reached
2. Claude Code displays "/rate-limit-options" in an infinite loop
3. No interaction is possible (no interruption, no prompt input)
4. After some time, Claude Code closes automatically and drops back to the project root
5. The entire session (conversation + history) is lost

Impact

• Complete loss of the ongoing conversation and session history
• Blocking user experience

What Should Happen?

Expected behavior
Display a clear error message once, allow the user to interact (exit cleanly, save the session, etc.)

Steps to Reproduce

1. Use Claude Code until the daily usage limit is reached
2. Observe Claude Code printing "/rate-limit-options" repeatedly (30+ times) with no way to stop it
3. Observe inability to interrupt the loop or send any input
4. Wait for automatic exit — Claude Code terminates and drops back to the project root, wiping the entire conversation history
