## ⚡ Quick Start

### Installation
```bash
pip install fixit-ai

or 

# Clean installation (recommended)
pip install fixit-ai --quiet
```

### FastAPI (Zero-Config)
```bash
# Start your FastAPI app
uvicorn main:app --reload

# Test with zero configuration
fixit init --fastapi main:app --base http://localhost:8000
fixit gen && fixit test && fixit fix && fixit sec
```

### Express.js
```bash
# Start your Express.js app with OpenAPI
node app.js

# Test your Express.js API
fixit init --express . --base http://localhost:3000
fixit gen && fixit test && fixit fix && fixit sec
```

### Universal (Any OpenAPI Framework)
```bash
fixit init --spec openapi.yaml --base http://localhost:8000
fixit gen && fixit test && fixit fix && fixit sec
```

## 🎯 What Fixit.AI Does

| Step | Command | What Happens |
|------|---------|--------------|
| **Initialize** | `fixit init` | 🔍 Auto-extracts OpenAPI spec, creates `fixit.toml` with LLM defaults |
| **Generate** | `fixit gen` | 📝 Creates comprehensive test suite covering all endpoints |
| **Test** | `fixit test` | 🧪 Runs tests with real-time AI analysis of failures |
| **Fix** | `fixit fix` | 🛠️ Shows AI-generated code patches (suggestions-only by default) |
| **Secure** | `fixit sec` | 🔒 Scans for OWASP API Security Top 10 vulnerabilities |

## 🤖 AI Integration

Fixit.AI works with **local LLMs** for private, offline analysis:

### Quick Setup (LM Studio)
1. **Download** [LM Studio](https://lmstudio.ai/)
2. **Install model**: `GPT-OSS 20B`
3. **Start server** on `localhost:1234`
4. **Run**: `fixit test` (auto-detects LM Studio)

### Alternative (Ollama)
```bash
# Install and setup
curl -fsSL https://ollama.ai/install.sh | sh
ollama pull phi3:mini

# Configure (optional - auto-detected)
fixit init --llm-provider ollama --llm-model phi3:mini
```

## 📋 Framework Support

| Framework | Language | Zero-Config | Code Patches | Security Scan |
|-----------|----------|-------------|--------------|---------------|
| **FastAPI** | Python | ✅ | ✅ | ✅ |
| **Express.js** | Node.js | ✅ | ✅ | ✅ |
| **Any OpenAPI 3.0+** | Any | ✅ | ✅ | ✅ |

## ⚙️ Configuration

**Auto-Generated `fixit.toml`** (created on first run):
```toml
llm_active = "llm"
openapi = "openapi.yaml"

[llm]
provider = "lmstudio"
# base_url = "http://localhost:11434/v1" # Ollama
base_url = "http://localhost:1234/v1"    # LM Studio
model = "gpt-oss20B"
temperature = 0.0
max_tokens = 2048
timeout_seconds = 180
offline = true
api_key_env = "FIXIT_API_KEY"

[llm.demo]
provider = "llama.cpp-stub"

[test]
include = []
exclude = []
max_tests = 0
concurrency = 8
```

**Override during init**:
```bash
fixit init --fastapi main:app --base http://localhost:8000 \
  --llm-provider ollama --llm-model phi3:mini
```
