🤖 AI Code Validator

Catch AI-generated code mistakes before they cause problems.

A CLI tool that analyzes AI-generated code for hallucinations, security vulnerabilities, and outdated patterns. Get a confidence score before you commit!

---

🎯 The Problem

66% of developers are frustrated with AI-generated code that's "almost right, but not quite"

45% say debugging AI code is more time-consuming than writing it themselves

20% of AI-generated code suggests non-existent packages (creating "slopsquatting" security risks)

62% of AI code contains security vulnerabilities, even from the latest models

AI Code Validator solves this by automatically detecting:

• 🔍 Hallucinated functions & APIs that don't actually exist
• 📦 Fake dependencies before you pip install or npm install them
• 🔒 Security vulnerabilities like SQL injection, XSS, and command injection
• ⚠️ Missing input validation (AI's #1 mistake)
• 📅 Outdated patterns from old training data
• 🔑 Hardcoded secrets that shouldn't be in code

---

⚡ Quick Start

Installation

pip install ai-code-validator

Basic Usage

# Check a single file
aivalidate check myfile.py

# Check entire directory
aivalidate check src/

# Check with JSON output (for CI/CD)
aivalidate check . --format json

# Install git pre-commit hook
aivalidate install-hook

📊 Example Output

==================================================================
🤖 AI CODE VALIDATOR - RESULTS
==================================================================

Confidence Score: 67/100 (FAIR)
Total Issues: 5
  Critical: 2 | High: 1 | Medium: 1 | Low: 1

Recommendation:
  ⚠️  CRITICAL: Hallucinated dependencies detected! Do NOT install these packages.

==================================================================
🚨 CRITICAL ISSUES (2)
==================================================================

[HALLUCINATED_DEPENDENCY]
  File: app.py:3
  Package "ai-utils-helper" does not exist on PyPI
  💡 Suggestion: AI may have hallucinated this package. This creates a "slopsquatting" security risk.

[SQL_INJECTION]
  File: database.py:45
  Potential SQL injection: String concatenation in SQL query
  💡 Suggestion: Use parameterized queries or prepared statements instead

==================================================================
⚠️  HIGH SEVERITY ISSUES (1)
==================================================================

[MISSING_INPUT_VALIDATION]
  File: api.py:23
  User input without validation detected
  💡 Suggestion: AI often omits input validation. Add validation before using user input.

✨ Features

🔍 AI Hallucination Detection

• Detects non-existent functions and methods
• Identifies fake API endpoints
• Spots missing call sites and dependencies

📦 Dependency Validation

• Checks if packages exist on PyPI, npm, etc.
• Prevents "slopsquatting" attacks
• Validates imports in real-time

🔒 Security Scanning

• SQL injection detection
• XSS vulnerability checks
• Command injection patterns
• Hardcoded secrets detection
• Missing input validation (AI's most common mistake)

📊 Confidence Scoring

• 0-100 score based on issue severity
• Clear ratings: EXCELLENT → CRITICAL
• Actionable recommendations

🎨 Beautiful Output

• Color-coded severity levels
• Clear issue descriptions
• Helpful suggestions for fixes
• JSON output for CI/CD integration

🔧 Git Integration

• One-command pre-commit hook installation
• Automatic validation on every commit
• Only checks staged files

🚀 Usage Examples

Basic File Checking

# Single file
aivalidate check app.py

# Multiple files
aivalidate check app.py utils.py models.py

# Entire directory (recursively)
aivalidate check src/

# Current directory
aivalidate check .

Filtering by Severity

# Only critical issues
aivalidate check . --severity critical

# Critical and high only
aivalidate check . --severity high

# All issues (default)
aivalidate check . --severity all

Output Formats

# Human-readable colored output (default)
aivalidate check .

# JSON output for parsing
aivalidate check . --format json

Speed Optimization

# Skip dependency checking (faster, but less thorough)
aivalidate check . --no-deps

Git Integration

# Install pre-commit hook
aivalidate install-hook

# Now runs automatically on git commit!

# To bypass (not recommended):
git commit --no-verify

🏗️ How It Works

AI Code Validator uses a multi-layer analysis approach:

1. AST Parsing - Analyzes code structure using Abstract Syntax Trees
2. Pattern Matching - Detects common AI hallucination patterns
3. Dependency Verification - Checks package registries (PyPI, npm) in real-time
4. Security Analysis - Scans for OWASP Top 10 vulnerabilities
5. Scoring Algorithm - Calculates confidence score with severity weighting
6. Smart Reporting - Groups and prioritizes issues for quick fixes

Supported Languages

• ✅ Python (.py)
• ✅ JavaScript (.js, .jsx)
• ✅ TypeScript (.ts, .tsx)
• ✅ Java (.java)
• ✅ Kotlin (.kt)
• 🚧 More coming soon!
