What's Wrong?

Description

The /usage command traps all keyboard input with no way to dismiss the view. The only way out is Ctrl+C /
Ctrl+D, which kills the entire Claude process.

Steps to reproduce

1. Open Claude Code CLI
2. Type /usage
3. Try to exit the view

What happens

• Escape does not dismiss the view
• Tab works to switch between tabs within the view
• No other keybinding dismisses it (tried :q, q, Escape)
• The usage tab shows a rate limit error (rate_limit_error: Rate limited. Please try again later.) despite

the conversation API working fine in the same session

• The only way out is Ctrl+C or Ctrl+D, which terminates the process entirely

What was tried

• Toggling vim mode off — no difference
• Running in both Fish and Bash shells — same behavior
• Escape, Tab, :q, q — none dismiss the view
• Only Ctrl+C/Ctrl+D work, but they kill the process

Environment

• Version: 2.1.86
• Shell: Fish and Bash (both affected)
• OS: Linux (NixOS)

What Should Happen?

Escape (or some keybinding) should dismiss the /usage view and return to the chat prompt without killing the process. The rate limit error on the usage endpoint while actively in a session is also unexpected (I am well below the limit).

Error Messages/Logs

Error: Failed to load usage data: {"error":{"type":"rate_limit_error","message":"Rate limited. Please try again later."

Steps to Reproduce

Type /usage at any point. Get stuck forever.
