## What it is
AI Hero is an open-source collection of course material, runnable examples, exercises, and libraries for learning AI engineering, created by Matt Pocock. It accompanies the aihero.dev course and includes agent workflow skills (like /grill-with-docs) and the Evalite evals framework.

## Use cases
- learn ai engineering from scratch
- transition from web development to ai engineering
- find runnable llm examples with vercel ai sdk
- learn to build ai coding agent workflows
- set up claude code and ralph loops
- learn llm evaluation with evalite
- study ai engineering course exercises

## When to choose
- you are a frontend, backend, or full-stack developer moving into AI work
- you want self-contained, runnable TypeScript examples for LLM concepts
- you want free installable skills for structuring AI coding agent workflows
- you prefer learning alongside a structured course with articles

## When to avoid
- you need a production-ready AI framework or SDK rather than educational material
- you work outside the Node.js/TypeScript ecosystem
- you want a turnkey application rather than examples and exercises
- you need guaranteed stability, since content is actively evolving with TODOs
