around an agent.
A practical book
The Agentic Engineering Guide
A practical book for software, data and AI engineers building systems where a model can choose actions, use tools and keep working toward a goal.
“An agent is a loop. The harness makes the loop reliable. Context is the fuel it burns. Verification decides what counts as done.”

Methods worth keeping
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”.
