> **Industry-grade security scanner for AI-generated code** with AST analysis, taint tracking, and LLM-specific vulnerability detection.

AI coding assistants (GitHub Copilot, Claude, ChatGPT, Cursor) are revolutionizing development—but they can introduce security vulnerabilities that slip past code review. **AI Code Guard Pro** is a next-generation security scanner specifically designed to catch these issues.

## 🚀 Key Improvements Over Basic Scanners

| Feature | Basic Scanners | AI Code Guard Pro |
|---------|---------------|-------------------|
| **Analysis Method** | Regex matching | AST parsing + taint tracking |
| **False Positives** | High | Reduced via context awareness |
| **Secret Detection** | Pattern only | Pattern + Shannon entropy |
| **Prompt Injection** | ❌ Not detected | ✅ Direct + indirect detection |
| **Supply Chain** | Basic | Typosquatting + dependency confusion |
| **Output Formats** | Limited | Console, JSON, SARIF, Markdown |
| **CI/CD Integration** | Basic | Native SARIF for GitHub Security |

## 🎯 What It Detects

### 🔐 Secrets & Credentials
- **API Keys**: OpenAI, Anthropic, AWS, GCP, GitHub, Stripe, and 15+ providers
- **Private Keys**: RSA, SSH, PGP, EC
- **Database Credentials**: Connection strings, passwords
- **High-Entropy Strings**: AI placeholder secrets

### 💉 Injection Vulnerabilities
- **SQL Injection**: f-strings, .format(), concatenation in queries
- **Command Injection**: os.system, subprocess with shell=True
- **Code Execution**: eval(), exec() with user input
- **SSRF**: User-controlled URLs in requests

### 🤖 AI/LLM-Specific Issues
- **Direct Prompt Injection**: User input in system prompts
- **Indirect Injection**: RAG/retrieval injection risks
- **Unsafe Deserialization**: pickle, yaml.load without SafeLoader

### 📦 Supply Chain Attacks
- **Typosquatting**: Similar names to popular packages
- **Dependency Confusion**: Internal package name patterns
- **Known Malicious Packages**: Database of suspicious packages

## 📦 Installation

```bash
pip install ai-code-guard
```

Or with development dependencies:

```bash
pip install ai-code-guard[dev]
```

## 🔧 Quick Start

```bash
# Scan a directory
ai-code-guard scan ./src

# Scan with specific output format
ai-code-guard scan ./src --format sarif -o results.sarif

# Quick CI check
ai-code-guard check ./src

# List all rules
ai-code-guard rules

# Create config file
ai-code-guard init
```

## 🔬 Technical Details

### AST-Based Analysis

Unlike regex-based scanners, AI Code Guard Pro parses Python code into an Abstract Syntax Tree, enabling:

- **Taint tracking**: Follow user input through variable assignments
- **Context awareness**: Understand function calls and their arguments
- **Reduced false positives**: Skip patterns in comments and strings

### Entropy-Based Secret Detection

Uses Shannon entropy to distinguish real secrets from placeholders:

```python
# High entropy (likely real secret) - DETECTED
api_key = "sk-proj-aB3xK9mL2pQrStUvWxYz..."

# Low entropy (placeholder) - IGNORED
api_key = "your-api-key-here"
```

### LLM Security Focus

Specifically targets vulnerabilities in AI/LLM applications:

- Detects prompt injection in OpenAI, Anthropic, and LangChain code
- Identifies indirect injection risks in RAG pipelines
- Flags unsafe patterns in agent/tool implementations

### Adding Detection Patterns

```python
# ai_code_guard_pro/analyzers/my_analyzer.py
from ai_code_guard_pro.models import Finding, Severity, Category

class MyAnalyzer:
    def analyze(self) -> list[Finding]:
        findings = []
        # Your detection logic
        return findings
```
