Workflow Overview

Each tutorial follows the same pattern:

1. Create a Spin component - Implement tool handlers in your language of choice
2. Register in spin.toml - Add your component to the main Spin configuration
3. Build and run - Compile to WASM and start the Spin server
4. Configure DeepFabric - Define your tools in the YAML config with component: routing
5. Generate datasets - Run DeepFabric to create training data using your tools

Prerequisites

All tutorials assume you have:

• Spin CLI installed
• Language-specific toolchain (Rust/TinyGo/Python/Node.js)
• DeepFabric CLI installed
