TOTAL	39	13	26

What Gets Blocked (13 Critical Checks)

These will prevent commits/pushes until fixed:

Pre-Commit (7 blocking)

1. Merge conflict markers (<<<<<<<, =======, >>>>>>>)
2. Non-ASCII filenames
3. Missing shebang in executable scripts
4. Package.json with invalid JSON
5. Secrets/API keys in staged files
6. .env files being committed
7. Large files >10MB
8. Sensitive file patterns (*.pem, credentials.json, etc.)

Commit-Msg (6 blocking)

1. Subject line >100 characters
2. WIP commits
3. Profanity/inappropriate language
4. Fixup/squash commits on main/master
5. Claude Code attribution lines ✅ (solves your original issue)
6. Secrets in commit messages

What Gets Warned (26 Informational Checks)

These show warnings but don't block commits:

Code Quality (10 warnings)

• Trailing whitespace
• Hardcoded localhost/127.0.0.1 URLs
• Large commented code blocks (>30%)
• Empty catch blocks
• process.exit() in library code
• TypeScript any type usage

• TypeScript type errors

Commit Message Quality (6 warnings)

• All caps subject lines
• Period at end of subject
• Empty scope in conventional commits
• Merge commits on feature branches
• Missing body on substantial commits (feat/refactor/perf)

Pre-Push Quality (10 warnings)

• Branch naming conventions
• Untracked files detection
• Uncommitted changes
• High commit count (>10 ahead of remote)
• Large commits (>5MB)
• Direct push to main/master
• Too many TODOs added (>5)
• Merge conflict mentions

Special Features

Claude Attribution Prevention ✅

The original issue has been completely solved:

git commit -m "feat: add feature

# Commit blocked!

Bypass Mechanisms

For warnings: Add // OK: comment to the line to bypass:

console.log("Important production log") // OK: needed for monitoring

For blocking checks: Use --no-verify flag (use sparingly!):

git commit --no-verify -m "emergency fix"
git push --no-verify

Commits

Testing

All hooks have been tested and are working correctly:

# Test pre-commit
git add test.ts
git commit -m "test"
# Runs 17 checks ✓

# Test commit-msg
echo "WIP: test" | .husky/commit-msg /dev/stdin
# Blocks WIP commits ✓

# Test pre-push
git push
# Runs 10 checks, completes successfully ✓

Performance

• Pre-commit: ~2-3 seconds for typical commits
• Commit-msg: <1 second
• Pre-push: ~1-2 seconds (tests disabled by default)

Maintenance

To update hooks:

vim .husky/pre-commit      # Edit pre-commit checks
vim .husky/commit-msg      # Edit commit message checks
vim .husky/pre-push        # Edit pre-push checks
chmod +x .husky/*          # Ensure executable

To reinstall hooks:

npm run prepare
# or
bunx husky install

Benefits

1. Security: Prevents secrets, credentials, and .env files from being committed
2. Quality: Enforces code standards and best practices
3. Professionalism: Blocks inappropriate language, WIP commits to main
4. Consistency: Enforces conventional commits format
5. Efficiency: Catches issues before CI/CD, saving time
6. Attribution: Blocks Claude Code attribution as required ✅
