Not a Replacement — A New Layer

Let's be clear: Open Code Review doesn't replace ESLint or SonarQube. It adds a new detection layer specifically designed for AI-generated code defects.

What Each Tool Catches

#### ESLint
  • ✅ Code style violations
  • ✅ Unused variables
  • ✅ Missing semicolons
  • ✅ Import order
  • ❌ Hallucinated packages
  • ❌ Stale APIs
  • ❌ Cross-file logic gaps
#### SonarQube
  • ✅ Code smells
  • ✅ Security vulnerabilities (known patterns)
  • ✅ Test coverage metrics
  • ✅ Duplicated code
  • ❌ Phantom dependencies
  • ❌ AI-specific anti-patterns
  • ❌ Auto-fix capabilities
#### Open Code Review
  • ✅ Hallucinated packages (verified against registries)
  • ✅ Stale/deprecated APIs (training cutoff awareness)
  • ✅ Cross-file logic discontinuities
  • ✅ AI-specific security anti-patterns
  • ✅ Over-engineering detection
  • Auto-heal (fix, not just report)
  • ❌ Code style (use ESLint)
  • ❌ Test coverage metrics (use SonarQube)

The Ideal Stack

ESLint          → Code style & syntax
SonarQube       → Traditional bugs & security
Open Code Review → AI-specific defects & auto-heal

These three tools are complementary, not competitive. Each catches a different class of issues.

Real Scenario: Why You Need All Three

Consider this AI-generated code:

import { fastHash } from 'crypto-fast-hash';
import { createServer } from 'http';

const server = createServer((req, res) => { const hash = fastHash(req.url); res.writeHead(200); res.end(hash); });

  • ESLint: ✅ No style issues
  • SonarQube: ✅ No known vulnerability patterns
  • TypeScript: ✅ Compiles with mocked types
  • Open Code Review: 🚨 crypto-fast-hash doesn't exist on npm!

Getting Started with the Full Stack

# Add OCR to your existing CI alongside ESLint and SonarQube
npx @opencodereview/cli@latest scan ./src --level l3
npx @opencodereview/cli@latest heal ./src

No need to remove any existing tools. OCR runs alongside them in your pipeline.
