Safe Commit

• No actual project absolute paths (generic examples are OK)
• No internal/private domains or IPs
• No API keys or credentials
• No sensitive company/infrastructure information
• Context matters - use judgment based on project knowledge

Step 2: Stage Files (Only Changed Files for This Task)

# Stage specific files modified in current task
git add file1.php
git add file2.tsx

NEVER use:

• git add . - Too broad
• git add -A - Stages everything
• git add * - Uncontrolled

Step 3: Run Automated Validation

# Automated security checks
bash .claude/skills/safe-commit/scripts/validate.sh

Script checks for common patterns (but Codex's manual review in Step 1 is still required).

Step 4: Create Commit

Option A: Using Helper Script (Recommended)

bash .claude/skills/safe-commit/scripts/commit.sh \
  "feat(feature): brief description" \
  "- Detailed change 1
- Detailed change 2
- Detailed change 3"

You can set the commit author name with AGENT_NAME (default: Codex) and commit tag with AGENT_TAG (default derived from AGENT_NAME, e.g. AntiGravity → ANTIGRAVITY):

AGENT_NAME=AntiGravity AGENT_TAG=ANTIGRAVITY bash .claude/skills/safe-commit/scripts/commit.sh \
  "docs(git): [ANTIGRAVITY] update safe-commit author/tag" \
  "- Allow configurable commit author via AGENT_NAME\n- Allow configurable commit tag via AGENT_TAG"

Option B: Manual Commit

USER_EMAIL=$(git config user.email)

git commit --author="AntiGravity <$USER_EMAIL>" -m "type(scope): [ANTIGRAVITY] description

- Change details

Co-Authored-By: AntiGravity <[email protected]>"

Step 5: Verify Commit

# Check author and message
git log -1 --format='%an: %s'
# Expected: AntiGravity: [ANTIGRAVITY] type(scope): description

Critical Security Rules

Automated Validation (Script)

The validate.sh script performs basic pattern matching:

• API key/token patterns
• Absolute path patterns
• .env value patterns
• Database credential patterns

Manual Validation (Codex MUST Review)

Before committing, Codex MUST manually review git diff --cached and check:

❌ MUST NOT include:

1. API Keys/Tokens/Secrets

   • AWS keys (AKIA..., aws_secret_access_key)
   • GitHub tokens (ghp_..., github_token)
   • JWT tokens, Bearer tokens
   • Third-party API keys (Stripe, SendGrid, etc.)
   • Encryption keys, private keys

2. Absolute File Paths (Context-dependent)

   • ✅ OK: Documentation examples using generic paths (/home/username/...)
   • ❌ REJECT: Actual project paths (/root/liveserver2024/..., /var/www/official-en-aia/...)
   • Check if path reveals sensitive infrastructure information

3. Private Domains/Internal URLs (Context-dependent)

   • ✅ OK: Public testing domains (e.g., example.com, test.example.com)
   • ❌ REJECT: Internal infrastructure (e.g., internal-api.company.local, 10.0.0.5)
   • Check if domain reveals company/project private information

4. .env File Values

   • ✅ OK: Empty structure (DB_HOST=, API_KEY=)
   • ❌ REJECT: Any actual values (DB_PASSWORD=secret123)

5. Database Credentials

   • Any connection strings with passwords
   • Database URLs with credentials
   • Redis/Memcached auth tokens

6. Other Sensitive Data

   • Email addresses (except in git metadata)
   • Phone numbers
   • Physical addresses
   • Internal server IPs
   • Docker container paths revealing infrastructure

Commit Requirements

✅ MUST include:

• [$AGENT_TAG] tag in description: type(scope): [$AGENT_TAG] description
• Conventional commit format maintained
• Co-Authored-By: <AgentName> <[email protected]> footer
• --author="<AgentName> <email>" parameter (does NOT modify .git/config)

Commit Types

Example Usage

# Feature commit
git add app/Http/Controllers/NewsController.php resources/js/pages/news.tsx
bash .claude/skills/safe-commit/scripts/commit.sh \
  "feat(news): [$AGENT_TAG] add news listing page with filters" \
  "- Implement NewsController with pagination
- Create React news page component
- Add PostResource for data formatting"

# Bug fix commit
git add laravel/config/cache.php
bash .claude/skills/safe-commit/scripts/commit.sh \
  "fix(cache): [$AGENT_TAG] resolve response cache not clearing" \
  "- Update cache configuration
- Add cache clear to deployment workflow"

Validation Script

The validate.sh script performs these checks:

Phase 1: Regex-based Checks (Fast)

1. ✓ Staged changes exist
2. ✓ No API keys/tokens/secrets
3. ✓ No absolute file paths
4. ⚠ No private domains (warning only)
5. ✓ No .env variable values
6. ✓ No database credentials

Phase 2: AI-powered Validation (Optional)

When enabled, uses Codex CLI for intelligent sensitive data detection:

Environment Variables:

Usage Examples:

# Use Codex for AI validation (default)
USE_AI_VALIDATION=1 bash .claude/skills/safe-commit/scripts/validate.sh

# Use Gemini for AI validation
AI_VALIDATOR=gemini bash .claude/skills/safe-commit/scripts/validate.sh

# Use GitHub Copilot for AI validation
AI_VALIDATOR=copilot bash .claude/skills/safe-commit/scripts/validate.sh

# Disable AI validation (regex only, faster)
USE_AI_VALIDATION=0 bash .claude/skills/safe-commit/scripts/validate.sh

# Set max diff size for AI validation (default 50KB)
MAX_DIFF_SIZE=102400 bash .claude/skills/safe-commit/scripts/validate.sh

AI Validation Features:

• Uses codex exec --sandbox read-only for secure execution
• 60-second timeout to prevent hanging
• Automatic skip if diff exceeds MAX_DIFF_SIZE (saves API costs)
• Falls back to regex-only if Codex fails or times out

Exit codes:

• 0: All checks passed
• 1: Security violation found (commit blocked)

Verification

After committing, verify:

# Check author name
git log -1 --format='%an'
# Expected: Codex (or $AGENT_NAME)

# Check commit message
git log -1 --format='%s'
# Expected: type(scope): [$AGENT_TAG] description

# View full commit
git log -1 --format='%B'

Important Limitations

This skill handles commits ONLY. Do NOT:

• Push to remote (git push) - User must do manually
• Pull from remote (git pull) - User must do manually
• Merge branches (git merge) - User must do manually
• Rebase commits (git rebase) - User must do manually
• Modify .git/config - Use --author parameter instead

Integration with AGENTS.md

This skill implements the Git Commit Policy defined in AGENTS.md (Git Commit Policy section).

Success Criteria

✅ Commit created with [$AGENT_TAG] tag in description ✅ Author name matches $AGENT_NAME (default: Codex) ✅ Security validation passed ✅ Only relevant files staged ✅ Conventional commit format maintained (type at start) ✅ Co-Authored-By footer present ✅ .git/config NOT modified
