Build Your Claude Agent SDK Skill

Before learning Anthropic's Claude Agent SDK—the architecture behind Claude Code itself—you'll own a Claude Agent SDK skill.

Step 1: Get the Skills Lab

cd claude-code-skills-lab
claude

Step 2: Create Your Skill

Copy and paste this prompt:

Using your skill creator skill create a new skill for Claude Agent SDK
(Anthropic's agent framework). I will use it to build AI agents from
hello world to professional production systems. Use context7 skill to
study official documentation and then build it so no self assumed knowledge.

Claude will:

  • Fetch official Claude Agent SDK documentation via Context7
  • Ask you clarifying questions (tool patterns, subagent needs, hook requirements)
  • Create the complete skill with references and templates

Your skill appears at .claude/skills/claude-agent-sdk/.

Done

You now own a Claude Agent SDK skill built from official documentation. The rest of this chapter teaches you what it knows—and how to make it better.

Next: Lesson 1 — SDK Architecture

How to use it

Copy the folder

Take majiayu000/36-anthropic-agents-kit-development from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.
