# How It Works

## How It Works

### Phase 1: Requirements Analysis

```
User Request → Analyze needs → Determine:
- Target language (Node.js/Python/Go)
- Flow complexity (simple/multi-step/RAG)
- Model requirements (Gemini version, custom models)
- Deployment target (Firebase/Cloud Run/local)
```

### Phase 2: Project Setup

```
Check existing project → If new:
  - Initialize project structure
  - Install dependencies
  - Configure environment variables
  - Set up TypeScript/Python/Go config

If existing:
  - Analyze current structure
  - Identify integration points
  - Preserve existing code
```

### Phase 3: Implementation

```
Design flow architecture → Implement:
  - Input/output schemas (Zod/Pydantic/Go structs)
  - Model configuration
  - Tool definitions (if needed)
  - Retriever setup (for RAG)
  - Error handling
  - Tracing configuration
```

### Phase 4: Testing & Validation

```
Create test cases → Run locally:
  - Genkit Developer UI
  - Unit tests
  - Integration tests
  - Token usage analysis
```

### Phase 5: Production Deployment

```
Configure deployment → Deploy:
  - Firebase Functions (with AI monitoring)
  - Cloud Run (with auto-scaling)
  - Set up monitoring dashboards
  - Configure alerting
```
