AI Engineering

Build AI features the way production teams do: integrate the API with retries and streaming, write prompts against an eval set, ground answers with retrieval, force structured outputs, design tools for agents, cut costs with caching, and defend against prompt injection.

Best for Engineers adding LLM-powered features to a product.

What's inside

Listed in the order we suggest adopting them. You don't call them by name: each skill loads on its own when a request matches it.
