Engineering Agent Skills

Designing, evaluating, and maintaining procedural knowledge for AI agents.

“A skill gives an agent a reusable method for a particular kind of work. This book helps you decide what knowledge to package, how a request should find it, and what evidence would justify keeping it.”

A skill is a module whose interface is prose and whose runtime is a model. A skill asks, a hook decides. Judgment in prose, mechanics in code. Test “was it chosen” separately from “did it help”.
