Bug Report: /commit Slash Command Hanging Indefinitely in Claude Code 2.0.1

Summary

After updating to Claude Code 2.0.1, the /commit slash command hangs indefinitely without completing or providing feedback. The command appears to start but never finishes, requiring manual process termination.

Environment

• Claude Code Version: 2.0.1
• OS: macOS (Darwin 25.0.0)
• Platform: iOS development (Xcode project)

Steps to Reproduce

1. Make changes to files in a git repository
2. In Claude Code session, run /commit command
3. Observe "commit is running..." message appears
4. Wait indefinitely - command never completes
5. Check git status - no commit was created
6. Check processes: ps aux | grep git - no git processes running
7. Must cancel or restart Claude Code session to recover

Alternative reproduction:

1. Make changes to files
2. Run /commit with custom message: /commit "Fix bug in feature X"
3. Same result - hangs indefinitely with "commit is running..." message

Expected Behavior

• /commit command should analyze changes
• Should run SwiftFormat (if configured)
• Should create a git commit with generated or custom message
• Should complete within reasonable time (< 30 seconds typically)
• Should show commit hash/confirmation when complete
• Should fail gracefully with error message if issues occur

Actual Behavior

• Command shows initial "commit is running..." message
• No further output or progress updates
• No git commit is created
• No SwiftFormat runs
• No timeout occurs
• No error messages displayed
• Command hangs indefinitely until manually cancelled

Impact

• Cannot use /commit command at all
• Must manually run git add and git commit via Bash tool as workaround
• Loss of convenience features like automatic commit message generation
• Breaks workflow for users who rely on slash commands

Timeline

• Before: /commit command worked correctly in previous Claude Code version
• After: Updated to Claude Code 2.0.1, /commit command hangs on every attempt
• Attempts: Tried multiple times across different sessions - 100% reproduction rate

Workaround

Use direct git commands via Bash tool:

git add -A
git commit -m "Commit message"

This works correctly, confirming the issue is specific to the slash command system, not git itself.

Additional Investigation

Configuration Checked

• No git hooks configured that could be blocking
• Settings file shows empty hooks: "hooks": {}
• Pre-commit hooks run successfully when using direct git commit
• Direct git operations work fine

Process State

When /commit runs, no git processes are spawned:

$ ps aux | grep git
# No git processes found during hang

What Changed

User reports: "They were all working before I updated to the latest claude code"

Request

Please investigate the /commit slash command execution in Claude Code 2.0.1, particularly:

1. How the command spawns git processes
2. Whether it's waiting for input that never arrives
3. Timeout/cancellation mechanisms
4. Any changes to commit flow between versions

This makes the /commit command unusable in the current version.

What Should Happen?

Claude should execute the command

Error Messages/Logs

> /commit is running… <message>
  ⎿  Allowed 4 tools for this command

⏺ The /commit command is running with your custom message. Let me wait for it to complete - hopefully it won't
  hang this time.

Steps to Reproduce

1. Add settings to user scope
2. Add command to user scope
3. Run a claude session
4. Run /commit
