You can block dangerous git commands by installing a hook script into `.claude/hooks` and configuring it within the PreToolUse hooks in your `.claude/settings.json` file. This prevents operations like git push and git reset from executing.

Yes, you can apply git safety restrictions globally by placing the blockage script in `~/.claude/hooks` and configuring the settings globally. This applies command blocking across all projects using the Claude Code environment.

The best way to prevent unintended changes is to block destructive git operations before execution. Adding a customized shell script to your PreToolUse hooks stops commands like `git clean` and `git checkout .` from running.

You can customize blocked git commands by directly editing the hook script. This allows you to define specific command patterns to intercept and prevent from executing within your Claude Code setup.

No special dependencies are required. You only need a properly configured Claude Code environment to set up the hook script, make it executable, and add it to your settings to start blocking dangerous git commands.

Using a PreToolUse hook automates git security by intercepting dangerous commands before execution. This provides consistent code protection against operations like `git branch -D` without relying on manual oversight.
