What's Wrong?

Bug Description

When running claude /login in WSL2, the terminal enters an interactive
mode that blocks paste operations. The code generated by the OAuth flow
in the browser cannot be pasted back into the terminal.

Environment

• OS: Windows 11
• Shell: WSL2 (Ubuntu)
• Claude Code version: 2.1.107
• Terminal: Windows Terminal / PowerShell / cmd.exe

What Should Happen?

The code should be pasteable into the terminal to complete authentication.

Steps to Reproduce

Steps to Reproduce

1. Run claude /login inside WSL2
2. Open the generated URL in browser
3. Authenticate successfully
4. Try to paste the generated code back into the terminal
5. Paste fails (Ctrl+V, Ctrl+Shift+V, right-click, Shift+Insert — all fail)

Additional Notes

• Paste works normally in WSL2 terminal outside of the /login flow
• This started after a recent Claude Code update
• Workaround: using API Key directly (loses Claude Max subscription benefits)
