Environment

• Claude Code version: 2.1.37
• Platform: macOS (darwin)
• Shell: zsh

Steps to Reproduce

1. Run a git commit command via bash tool
2. Example command that hangs:

``bash
git add claude/settings.json zsh/.zshrc zsh/.zshrc.d/00-performance.zsh zsh/.zshrc.d/10-modern-tools.zsh nvim/.config/nvim/lazy-lock.json && git commit -m "refactor: simplify zsh config"
``

Expected Behavior

Command should execute and return results within a reasonable time.

Actual Behavior

Bash tool hangs indefinitely on single-line command execution.

Additional Context

• Was attempting to commit changes after refactoring zsh configuration
• Git status showed staged changes ready to commit
• Command works fine when run directly in terminal
