# Complete AI Repository Analysis Service

A comprehensive AI-powered repository analysis tool that automatically analyzes **ALL files** in a repository without any limits or user queries required.

## 🚀 Features

- **Complete Analysis**: Analyzes ALL files in the repository (no max-files limit)
- **Fully Automated**: No user query required - runs completely automatically
- **Memory-Enhanced**: Learns from previous analyses using advanced memory systems
- **Comprehensive Reports**: Generates detailed PDF reports with executive summaries
- **Multi-Database Support**: Uses PostgreSQL, MongoDB, and Redis for optimal performance
- **Security Focus**: Identifies security vulnerabilities and code quality issues
- **Architecture Assessment**: Provides architectural insights and recommendations

## 📋 Requirements

### System Dependencies
- Python 3.8+
- PostgreSQL with pgvector extension
- MongoDB
- Redis

### Python Dependencies
```bash
pip install anthropic python-dotenv git redis pymongo psycopg2-binary numpy reportlab
```

## 🛠️ Setup

1. **Install Dependencies**:
   ```bash
   pip install -r requirements.txt
   ```

2. **Database Setup**:
   ```bash
   # Run the database migration
   psql -U postgres -d repo_vectors -f 001-schema.sql
   ```

3. **Environment Variables**:
   Create a `.env` file with:
   ```env
   ANTHROPIC_API_KEY=your_api_key_here
   REDIS_HOST=localhost
   REDIS_PORT=6379
   REDIS_DB=0
   MONGODB_URL=mongodb://localhost:27017/
   MONGODB_DB=repo_analyzer
   POSTGRES_HOST=localhost
   POSTGRES_PORT=5432
   POSTGRES_DB=repo_vectors
   POSTGRES_USER=postgres
   POSTGRES_PASSWORD=your_password
   ```

## 🎯 Usage

### Basic Usage
```bash
python ai-analyze.py /path/to/repository
```

### With Custom Output
```bash
python ai-analyze.py /path/to/repository --output my_analysis.pdf
```

### With API Key Override
```bash
python ai-analyze.py /path/to/repository --api-key your_api_key
```

## 📊 What It Analyzes

### File Types Supported
- **Programming Languages**: Python, JavaScript, TypeScript, Java, C++, C#, Go, Rust, PHP, Ruby, Swift, Kotlin
- **Web Technologies**: HTML, CSS, SCSS, SASS
- **Configuration Files**: JSON, YAML, XML, SQL
- **Build Files**: Dockerfile, Makefile, CMake, package.json, requirements.txt, Cargo.toml, pom.xml, build.gradle
- **Documentation**: README.md, Markdown files

### Analysis Coverage
- **Code Quality**: Complexity, maintainability, best practices
- **Security**: Vulnerabilities, injection attacks, authentication issues
- **Architecture**: Project structure, scalability, design patterns
- **Performance**: Optimization opportunities, bottlenecks
- **Documentation**: Completeness and quality

## 📈 Output

### Console Output
- Real-time analysis progress
- Repository statistics
- Quality breakdown by file
- Language distribution
- Memory system statistics

### PDF Report
- Executive summary for leadership
- Repository overview with metrics
- Detailed file-by-file analysis
- Security assessment
- Architecture evaluation
- Recommendations and next steps

## 🧠 Memory System

The tool uses a sophisticated three-tier memory system:

1. **Working Memory (Redis)**: Temporary, fast access for current analysis
2. **Episodic Memory (MongoDB)**: User interactions and analysis sessions
3. **Persistent Memory (PostgreSQL)**: Long-term knowledge and best practices

This allows the tool to learn from previous analyses and provide increasingly accurate insights.

## 🔧 Configuration

### File Size Limits
- Default: 2MB per file (configurable in code)
- Large files are skipped with notification

### Excluded Directories
- `.git`, `node_modules`, `__pycache__`, `build`, `dist`, `target`
- `venv`, `env`, `.next`, `coverage`, `vendor`
- `bower_components`, `.gradle`, `.m2`, `.cargo`

### Rate Limiting
- 0.1 second delay between file analyses to avoid API rate limits
- Configurable in the code

## 🚨 Troubleshooting

### Common Issues

1. **Database Connection Errors**:
   - Ensure PostgreSQL, MongoDB, and Redis are running
   - Check connection credentials in `.env` file

2. **API Key Issues**:
   - Verify Anthropic API key is valid and has sufficient credits
   - Check rate limits if analysis fails

3. **Memory Issues**:
   - Large repositories may require more RAM
   - Consider increasing system memory or processing in batches

4. **File Permission Errors**:
   - Ensure read access to repository files
   - Check write permissions for output directory
