Pre-commit Hook Integration - API Key Detection

✅ Integration Complete

The API key detection has been successfully integrated into the existing Terraphim AI pre-commit hook without overwriting any existing functionality.

📋 What Was Changed

Enhanced Existing Pre-commit Hook

• Location: .git/hooks/pre-commit
• Integration: Added comprehensive API key detection to existing secret scanning section
• Preserved: All existing checks (Rust formatting/linting, JS/TS with Biome, YAML/TOML syntax, trailing whitespace, large files)
• Fallback: Basic pattern detection if comprehensive script isn't available

Updated Installation Script

• Location: scripts/install-pre-commit-hook.sh
• Smart Detection: Detects existing hooks and integrates rather than overwriting
• Backup: Creates timestamped backups of existing hooks
• Testing: Validates integration after installation

🔧 How It Works

Pre-commit Flow

1. Large File Check ✓ (existing)
2. API Key Detection ✨ (enhanced with comprehensive patterns)
3. Rust Formatting ✓ (existing)
4. Rust Linting (Clippy) ✓ (existing)
5. JS/TS Biome Checks ✓ (existing)
6. Trailing Whitespace Fix ✓ (existing)
7. YAML/TOML Syntax ✓ (existing)
8. Conventional Commit Format ✓ (existing)

API Key Detection Enhancement

• Primary: Uses scripts/check-api-keys.sh for comprehensive detection
• Fallback: Basic pattern matching if script unavailable
• Patterns Detected:
  • Cloudflare Account IDs and API tokens
  • AWS access keys and secrets
  • GitHub tokens
  • Google API keys
  • Generic API keys, secrets, tokens
  • Hardcoded credential patterns

🧪 Testing Results

Successful Integration Test

# Installation detects existing hook
./scripts/install-pre-commit-hook.sh
# ✅ API key detection already integrated in existing pre-commit hook

# Test with hardcoded credentials
echo 'const API_KEY = "sk-1234567890abcdef";' > test.js  # pragma: allowlist secret
git add test.js
git commit -m "test"
# ❌ API keys or credentials detected! (Successfully blocked)

Hook Output Example

Running Terraphim AI pre-commit checks...
Checking for large files...
✓ No large files found
Checking for secrets and sensitive data...
✗ API keys or credentials detected!

Running detailed scan...
ERROR: Potential API key found in: test.js
  Pattern: generic_api_key
    Line 1: const API_KEY = "sk-1234567890abcdef";  # pragma: allowlist secret

ERROR: 🚨 API key violations detected!

🎯 Benefits

1. Zero Disruption: All existing pre-commit functionality preserved
2. Enhanced Security: Comprehensive API key detection integrated seamlessly
3. Smart Installation: Detects and integrates with existing hooks
4. Robust Fallback: Works even if comprehensive script isn't available
5. Clear Feedback: Detailed error reporting for developers

🚀 Usage

For Developers

• Hook runs automatically on every commit
• Blocks commits containing hardcoded credentials
• Provides detailed scan results for remediation
• Preserves all existing development workflow

For New Team Members

# One-time setup (if needed)
./scripts/install-pre-commit-hook.sh

Manual Testing

# Test API key detection
./scripts/check-api-keys.sh

# Test full pre-commit hook
git add <files>
git commit -m "your message"

🔐 Security Status

• ✅ Hardcoded Credentials Removed: From browser extension
• ✅ Secure Storage Implemented: Chrome storage for API credentials
• ✅ Comprehensive Detection: 15+ API key pattern types
• ✅ Pre-commit Protection: Automatic scanning on every commit
• ✅ Developer Documentation: Clear setup and usage guides
• ✅ Fallback Protection: Basic patterns if script unavailable

🛡️ Repository is now protected against accidental credential commits while maintaining all existing development workflows!
