# 📚 Documentation Impact Analyzer
[](https://opensource.org/licenses/Apache-2.0)
[](https://symfony.com/)
[](https://php.net/)
An AI-powered tool that analyzes merge requests and automatically determines if code changes require user documentation updates. Built with Symfony 7.3 and powered by OpenAI's GPT models, it helps maintain documentation quality by flagging changes that impact user-facing features, APIs, or configurations.
## ✨ Features
### 🤖 Intelligent Analysis
- **AI-Powered Detection**: Uses Claude 3.5 Sonnet to analyze code changes and determine documentation impact
- **File-Type Awareness**: Intelligent categorization of changed files (controllers, models, config, templates, etc.)
- **Context-Aware Prompts**: Tailored analysis based on the type of changes detected
- **Multi-Level Impact**: Categorizes changes from NONE to CRITICAL impact levels
### 🔗 Git Provider Integration
- **GitHub Support**: Complete webhook integration with signature validation
- **GitLab Support**: Full API integration with merge request handling
- **Secure Webhooks**: HMAC signature validation for both platforms
- **Real-time Processing**: Instant analysis when merge requests are created or updated
### 💬 Professional Comments
- **Beautiful Formatting**: Rich markdown comments with emojis and structured sections
- **Actionable Suggestions**: Specific, practical documentation recommendations
- **Code Examples**: Automatic formatting of code snippets, API endpoints, and configuration
- **Impact Warnings**: Clear indicators for high-impact changes requiring immediate attention
### 🧪 Comprehensive Testing
- **30+ Tests**: Full test coverage with unit, integration, and end-to-end tests
- **94+ Assertions**: Robust validation of all functionality
- **Mock AI Responses**: Consistent testing without API dependencies
- **Webhook Testing**: Complete validation of webhook processing
## 🚀 Quick Start
### Prerequisites
- PHP 8.3 or higher
- Composer
- PostgreSQL 17
- Anthropic API key
- Git provider tokens (GitHub/GitLab)
### Installation
1. **Clone the repository**
```bash
git clone https://github.com/upsun/demo-symfony-mr-docs-impact.git
cd demo-symfony-mr-docs-impact
```
2. **Install dependencies**
```bash
composer install
```
3. **Configure environment**
```bash
cp .env.example .env
```
Edit `.env` with your configuration:
```bash
# Database
DATABASE_URL="postgresql://user:pass@127.0.0.1:5432/mr_docs_impact"
# Git Providers
GITHUB_TOKEN=your-github-token
GITHUB_WEBHOOK_SECRET=your-webhook-secret
GITLAB_TOKEN=your-gitlab-token
GITLAB_WEBHOOK_SECRET=your-webhook-secret
# AI Configuration
ANTHROPIC_API_KEY=your-anthropic-api-key
```
4. **Set up database**
```bash
# Using Docker
docker-compose up -d database
# Or with local PostgreSQL
createdb mr_docs_impact
```
5. **Start the server**
```bash
symfony local:server:start --allow-all-ip
```
### Docker Setup
Use Docker Compose for a complete development environment:
```bash
docker-compose up -d
```
This starts:
- PostgreSQL 17 database
- PHP 8.3 application server
- All necessary dependencies
## 🔧 Configuration
### Webhook Setup
#### GitHub
1. Go to your repository settings → Webhooks
2. Add webhook URL: `https://your-domain.com/webhook/github`
3. Content type: `application/json`
4. Events: `Pull requests`
5. Secret: Set your `GITHUB_WEBHOOK_SECRET`
#### GitLab
1. Go to your project settings → Webhooks
2. Add webhook URL: `https://your-domain.com/webhook/gitlab`
3. Trigger: `Merge request events`
4. Secret token: Set your `GITLAB_WEBHOOK_SECRET`
### AI Configuration
The system uses Anthropic's Claude 3.5 Sonnet model for intelligent analysis. You can customize:
```yaml
# config/packages/ai.yaml
ai:
platform:
anthropic:
api_key: '%env(ANTHROPIC_API_KEY)%'
```
## 📊 How It Works
### 1. Webhook Reception
When a merge request is created or updated, the system receives a webhook from your Git provider.
### 2. Change Analysis
The AI analyzer examines:
- **File Types**: Controllers, models, configuration, templates, etc.
- **Change Patterns**: New features, API modifications, breaking changes
- **Context**: Commit messages, branch names, file locations
- **Diff Content**: Actual code changes and their implications
### 3. Impact Assessment
Changes are categorized into impact levels:
| Level | Description | Action |
|-------|-------------|---------|
| 🚨 **CRITICAL** | Breaking changes requiring immediate action | Blocks merge until documented |
| 🔴 **HIGH** | New features or significant API changes | Prioritize documentation |
| 🟠 **MEDIUM** | Enhancements or configuration changes | Document when convenient |
| 🟡 **LOW** | Minor improvements or bug fixes | Optional documentation |
| ✅ **NONE** | Internal changes with no user impact | No documentation needed |
### 4. Comment Generation
Professional comments are posted to the merge request with:
- Clear impact assessment
- Specific affected documentation areas
- Actionable suggestions with examples
- Links to documentation guidelines
