What's Wrong?

Description

Pressing Enter in the Claude Code CLI does not submit the prompt. The cursor moves to a new line instead of sending the message. This makes the CLI completely unusable from the terminal.

Environment

• OS: Windows 11 Home Single Language, build 10.0.26200
• Shell: bash (Git Bash)
• Claude Code version: 2.1.116

Steps to reproduce

1. Open a terminal (Git Bash on Windows 11)
2. Run claude
3. Type any message
4. Press Enter
5. The prompt does not send — cursor moves to a new line

What Should Happen?

Expected behavior

Pressing Enter submits the prompt and Claude responds.

Actual behavior

Enter creates a new line instead of submitting. The CLI is stuck and the only way to interact is via the VS Code extension.

Workaround

Using the Claude Code VS Code extension works correctly. The issue is specific to the terminal CLI.

Additional context

This may be related to how the CLI handles keyboard input in Windows native terminals. Shift+Enter and other combinations also do not submit.
