# Setup Git Guardrails Sets up a PreToolUse hook that intercepts and blocks dangerous git commands before Claude executes them. ## What Gets Blocked - `git push` (all variants including `--force`) - `git reset --hard` - `git clean -f` / `git clean -fd` - `git branch -D` - `git checkout .` / `git restore .` When blocked, Claude sees a message telling it that it does not have authority to access these commands. ## Steps ### 1. Ask scope Ask the user: install for **this project only** (`.claude/settings.json`) or **all projects** (`~/.claude/settings.json`)? ### 2. Copy the hook script The bundled script is at: [scripts/block-dangerous-git.sh](scripts/block-dangerous-git.sh) Copy it to the target location based on scope: - **Project**: `.claude/hooks/block-dangerous-git.sh` - **Global**: `~/.claude/hooks/block-dangerous-git.sh` Make it executable with `chmod +x`. ### 3. Add hook to settings Add to the appropriate settings file: **Project** (`.claude/settings.json`): ```json { "hooks": { "PreToolUse": [ { "matcher": "Bash", "hooks": [ { "type": "command", "command": "\"$CLAUDE_PROJECT_DIR\"/.claude/hooks/block-dangerous-git.sh" } ] } ] } } ``` **Global** (`~/.claude/settings.json`): ```json { "hooks": { "PreToolUse": [ { "matcher": "Bash", "hooks": [ { "type": "command", "command": "~/.claude/hooks/block-danger
