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

Go to github.com/panaversity/claude-code-skills-lab
Click the green Code button
Select Download ZIP
Extract the ZIP file
Open the extracted folder in your terminal

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.

Skill Creator

by anthropics

vendor ×10

Create new skills, modify and improve existing skills, and measure skill performance. Use when users want to create a skill from scratch, edit, or optimize an existing skill, run evals to test a skill, benchmark skill performance with variance analysis, or optimize a skill's description for better triggering accuracy.

Guide for creating effective skills. This skill should be used when users want to create a new skill (or update an existing skill) that extends Claude's capabilities with specialized knowledge, workflows, or tool integrations.

Replace with description of the skill and when Claude should use it.

Dispatching Parallel Agents

by ZhanlinCui

×5

Use when facing 2+ independent tasks that can be worked on without shared state or sequential dependencies

This skill should be used when the user wants to "create a skill", "add a skill to plugin", "write a new skill", "improve skill description", "organize skill content", or needs guidance on skill structure, progressive disclosure, or skill development best practices for Claude Code plugins.

Helps users discover and install agent skills when they ask questions like "how do I do X", "find a skill for X", "is there a skill that can...", or express interest in extending capabilities. This skill should be used when the user is looking for functionality that might exist as an installable skill.

Use when creating new skills, editing existing skills, or verifying skills work before deployment

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.
