Agent Skills Orange Book — Development skill for Claude Code

Agent Skills: The Complete Guide

From concept to practice, from installation to creation — the complete guide to AI skill systems.

**Agent Skills** is the open standard (agentskills.io) that lets you teach AI how you work. Instead of repeating instructions every conversation, you write a SKILL.md file once and your AI assistant remembers your workflow, preferences, and quality standards forever.

This book covers everything: what Skills are, how they work under the hood, where to find them, how to install and use them, how to create your own, and 6 advanced design patterns — including the thought-distillation pattern that emerged in 2026.
