What's Wrong?

Title: Bash commands completely fail on Windows with Git Bash (MINGW64)

Environment:

• Platform: Windows (win32)
• OS: MINGW64_NT-10.0-26200 3.6.4-b9f03e96.x86_64
• Shell: Git Bash
• Working directory: I:\wordpress-code
• Git Bash status: Works normally outside of Claude Code

Issue:
All bash commands fail with generic "Error" message and no output.
Even basic commands like pwd, ls, and cd return no output.

Commands tested:

• pwd
• ls -la
• cd subtopikal && pwd

All return: Error (with no additional information)

Expected: Commands should execute and return output
Actual: All commands fail silently with generic error message

Additional Information

Output from Claude for reporting:

Since Git Bash works fine independently but fails completely in Claude Code, this is a Claude Code integration bug.
The bash tool isn't properly communicating with Git Bash on your Windows system.

This needs to be reported to the Claude Code team:

Please report this issue at: https://github.com/anthropics/claude-code/issues

Unfortunately, I cannot fix this issue as it's within Claude Code's bash integration layer, not something I can
diagnose or repair from within the tool. The Claude Code team will need to investigate why bash execution is failing
on your Windows/Git Bash setup.

In the meantime, you can still use file operations (Read, Write, Edit, Glob, Grep) which don't rely on bash. Would you
like to work on your WordPress site or Chrome extension using those tools instead?
