|Installs a pre-commit review hook that forces code review by showing changes, detecting potential issues, and requiring user confirmation before committing.
Installation
npx skills add https://github.com/zbruhnke/claude-code-starter --skill install-precommitSkill Details
Install the pre-commit review hook that forces you to understand changes before committing. Use when you want to enable commit reviews or when setting up a new project.
Overview
You are helping the user install the pre-commit review hook.
What This Hook Does
The pre-commit review hook runs before every git commit and:
- Shows files being committed with their status (added/modified/deleted)
- Shows lines added and removed
- Detects potentially sensitive files (.env, secrets, keys)
- Detects debug statements (console.log, print, debugger, etc.)
- Shows new dependencies being added
- Shows TODOs being introduced
- Requires user confirmation (y/n/d for diff) before proceeding
This prevents "vibe coding" - blindly committing AI-generated code without understanding it.
Installation Steps
- Check prerequisites:
- Verify this is a git repository (.git directory exists)
- Check if a pre-commit hook already exists
- Create the hook script:
If .claude/hooks/pre-commit-review.sh doesn't exist, create it with the standard implementation.
- Install as git hook:
- Create .git/hooks/ directory if needed
- Copy or symlink the script to .git/hooks/pre-commit
- Make it executable
- Verify installation:
- Confirm the hook is in place
- Show the user how to test it
- Explain how to bypass if needed
Hook Script Source
The pre-commit hook script is located at .claude/hooks/pre-commit-review.sh.
Do NOT embed a copy here - always use the canonical version from the hooks directory. This ensures updates to the hook are applied everywhere.
If .claude/hooks/pre-commit-review.sh doesn't exist in the user's project, they may need to copy it from a template or create it based on their needs.
After Installation
Tell the user:
- The hook is now active for all future commits
- To skip the review (not recommended):
SKIP_PRE_COMMIT_REVIEW=1 git commit -m "message" - To uninstall:
rm .git/hooks/pre-commit
Output Format
```
[OK] Pre-commit review hook installed
Location: .git/hooks/pre-commit
Source: .claude/hooks/pre-commit-review.sh
The hook will run before every commit, showing:
- Files being committed
- Lines added/removed
- Potential issues (sensitive files, debug statements)
- Requires your confirmation before proceeding
To test: stage some files and run git commit
To skip: SKIP_PRE_COMMIT_REVIEW=1 git commit -m "message"
To remove: rm .git/hooks/pre-commit
```
