# Clean installation (recommended)
pip install fixit-ai --quiet

FastAPI (Zero-Config)

# 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

# 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)

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)

🤖 AI Integration

Fixit.AI works with local LLMs for private, offline analysis:

Quick Setup (LM Studio)

1. Download LM Studio
2. Install model: GPT-OSS 20B
3. Start server on localhost:1234
4. Run: fixit test (auto-detects LM Studio)

Alternative (Ollama)

# 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
