How is Open Code Review different from ESLint?

ESLint enforces code style rules and catches syntax-level issues. Open Code Review detects AI-specific defects like hallucinated packages, phantom dependencies, and stale APIs that ESLint cannot detect — and auto-fixes them with AI.

Can Open Code Review replace SonarQube?

Open Code Review complements SonarQube rather than replacing it. SonarQube excels at traditional code quality metrics and security scanning. OCR fills the gap by detecting AI-generated code defects that SonarQube misses, such as hallucinated package imports and context-broken logic.

What can Open Code Review detect that CodeQL cannot?

CodeQL focuses on semantic security analysis using query-based pattern matching. OCR detects AI-specific issues like npm packages that don't exist (hallucinations), APIs deprecated after an LLM's training cutoff, and cross-file logic gaps introduced by context window limitations.

Tool Comparison

OCR vs Traditional Code Quality Tools

Traditional tools check style and known vulnerabilities. OCR detects 5 categories of AI-specific defects — and auto-fixes them.

Why Traditional Tools Aren't Enough

ESLint, SonarQube, and CodeQL are excellent tools — but they were designed for human-written code. AI-generated code has 5 categories of unique defects (hallucinated packages, stale APIs, context-broken logic, hidden security anti-patterns, over-engineering) that traditional tools completely miss. OCR doesn't replace them — it fills their blind spots.

Real-World Scenarios

Traditional QA all PASS → Production incident → OCR would have caught it.

Hallucinated npm Package

AI generates import for "express-validator-plus" — a package that doesn't exist on npm.

Traditional Tools

ESLint: ✅ PASS | SonarQube: ✅ PASS | CodeQL: ✅ PASS — All tools pass because the syntax is valid.

Open Code Review

OCR: ❌ BLOCKED — "express-validator-plus" not found on npm registry. Suggested fix: use "express-validator" instead.

Deprecated API from Training Cutoff

AI uses crypto.createCipher() which was deprecated in Node.js 10 but still compiles.

Traditional Tools

ESLint: ✅ PASS | SonarQube: ⚠️ Maybe | CodeQL: ✅ PASS — Hard to catch without deprecation rules.

Open Code Review

OCR: ❌ BLOCKED — crypto.createCipher() deprecated since Node.js 10. Auto-heal: replaced with crypto.createCipheriv().

Cross-File Logic Contradiction

auth.ts validates JWT with RS256, but config.ts sets algorithm to HS256. Each file passes individually.

Traditional Tools

ESLint: ✅ PASS | SonarQube: ✅ PASS | CodeQL: ⚠️ Maybe — Single-file analysis misses cross-file issues.

Open Code Review

OCR: ❌ BLOCKED — Algorithm mismatch: auth.ts expects RS256 but config.ts provides HS256. Auto-heal: unified to RS256.

Insecure Default from AI

AI sets CORS to allow all origins (*) and disables CSRF protection — "works in development".

Traditional Tools

ESLint: ✅ PASS | SonarQube: ⚠️ Maybe | CodeQL: ⚠️ Maybe — Configuration-level issues are hard to detect.

Open Code Review

OCR: ❌ BLOCKED — Insecure CORS (*) with CSRF disabled. Auto-heal: restricted to production domain, CSRF enabled.

When to Use What

Use ESLint

Code style consistency, formatting rules, naming conventions. ESLint is the standard for style.

Use SonarQube

Code quality gates, tech debt tracking, coverage reports. SonarQube is the enterprise platform.

Use CodeQL

Deep security analysis, semantic vulnerability detection, custom security queries. CodeQL is the security research tool.

Add OCR to Fill the Gap

5 categories of AI-specific defects (hallucinated packages, stale APIs, context gaps, hidden security anti-patterns, over-engineering) + auto-heal. OCR fills the gaps they can't see.
