Local Integration Example

If you want to integrate CodeAnt AI into your local CI/CD pipeline:

# .github/workflows/codeant.yml
name: CodeAnt AI Review

on:
  pull_request:
    branches: [main, develop]

jobs:
  review:
    runs-on: ubuntu-latest

    steps:
      - uses: actions/checkout@v4
        with:
          fetch-depth: 0

      - name: Setup Node.js
        uses: actions/setup-node@v4
        with:
          node-version: '20'

      - name: Install CodeAnt CLI
        run: npm install -g @codeant/cli

      - name: Run CodeAnt Review
        run: |
          codeant review \
            --diff-base ${{ github.event.pull_request.base.sha }} \
            --diff-head ${{ github.event.pull_request.head.sha }} \
            --format json \
            --output results.json
        env:
          CODEANT_API_KEY: ${{ secrets.CODEANT_API_KEY }}

      - name: Comment PR
        uses: actions/github-script@v7
        with:
          script: |
            const fs = require('fs');
            const results = JSON.parse(fs.readFileSync('results.json'));
            // Post review comments to PR

Core Features

1. AI-Powered Code Review

CodeAnt AI analyzes code changes using advanced LLMs and provides intelligent feedback:

# Example: Before CodeAnt review
def calculate_discount(price, discount_percent):
    result = price * discount_percent
    return result

# CodeAnt detects: Missing division by 100, potential incorrect calculation
# Suggested fix:
def calculate_discount(price, discount_percent):
    """Calculate discount amount."""
    if discount_percent > 100:
        raise ValueError("Discount percent cannot exceed 100%")
    result = price * (discount_percent / 100)
    return result

2. Security Vulnerability Detection

Built-in security rules detect common vulnerabilities:

// Detected: SQL Injection vulnerability
const query = `SELECT * FROM users WHERE id = ${userId}`;
db.query(query);

// CodeAnt suggests: Use parameterized queries
const query = 'SELECT * FROM users WHERE id = ?';
db.query(query, [userId]);

3. Performance Optimization Suggestions

Identifies performance bottlenecks:

# Detected: Inefficient database queries in loop
for user in users:
    orders = db.execute(f"SELECT * FROM orders WHERE user_id = {user.id}")
    # Process orders

# Suggested improvement: Single query with JOIN
query = """
SELECT u.*, o.*
FROM users u
LEFT JOIN orders o ON u.id = o.user_id
WHERE u.id IN ({})
""".format(','.join(['?' for _ in users]))

4. Code Quality Metrics
