Overview
Instructions you repeat should be written once. This course shows how to write them as skills.
Introduction to agent skills is a one-hour Academy course on the reusable instruction files Claude Code applies on its own. You learn skill metadata and staged loading, when a skill beats a subagent, hook or MCP server, and how to debug one. Anthropic’s page says it has no completion badge, so finishing it earns no credential; it has six lessons and no quiz.

Course outline
From a SKILL.md file
From a SKILL.md file
to a skill your team can share.
We design this course ourselves. Anthropic issues the credential, and LUNARTECH is independent of Anthropic.
Skills are reusable instruction files that Claude applies on its own. You learn where they live, how Claude matches one to your request, and how they load in stages to save context.
- What a skill is and what it holds
- Where skills are stored
- How Claude matches a request to a skill
- Staged loading of metadata and body
- Skills you have already met
You build A map of the skills available in a project and when each would trigger.
You create a skill from scratch with a valid SKILL.md, then confirm that Claude Code loads it and that it does its job on a real request.
- The SKILL.md file layout
- Required metadata fields
- Writing the instruction body
- Checking that the skill loads
- Running it on a real request
You build A working skill that handles one repeated task, with a test request.
A skill triggers on its description. You write descriptions that match the right requests, pre-approve tools with allowed-tools, and split larger skills into supporting files and scripts.
- Writing descriptions that trigger well
- Describing when not to use a skill
- Pre-approving tools with allowed-tools
- Supporting files and references
- Bundling scripts with a skill
- Keeping skills small enough to load fast
You build A multi-file skill with a tuned description and a bundled script.
Claude Code has several ways to shape behavior. You decide when a skill fits better than CLAUDE.md, a subagent, a hook or an MCP server, using the nature of the task as your guide.
- Skills and CLAUDE.md
- Skills and subagents
- Skills and hooks
- Skills and MCP servers
- A decision rule for new needs
You build A decision table that places five real needs with the right feature.
A skill is useful once others can use it. You share skills through repositories, plugins and managed settings, and diagnose triggering, loading, priority and runtime problems with the validator and debug mode.
- Sharing through a repository
- Packaging skills in plugins
- Managed settings for an organization
- Skills used by custom subagents
- Using the validator
- Debug mode and priority conflicts
- Fixing a skill that never triggers
You build A shared skill with a short debugging guide for its known failure modes.

Reviews
Real stories from the community.
LUNARTECH Academy has been the most empowering learning experience of my life, giving me a clear, structured path from the absolute basics to building real-world AI systems with confidence.
Your page is fantastic. As a bachelor’s student in Data Science now accepted for a master’s at UConn, your work has been a real source of motivation.
The programme’s clear, bite-sized content and practical projects dramatically improved my speed from fuzzy idea to MVP and my ability to communicate AI value. I followed the system, and it works.
I really appreciate your teaching style and the way you break down complex topics. It has been incredibly helpful.
After years working mainly with R for econometrics, I found your Python machine learning course a refreshing and engaging way to learn Python.
As a Data Science graduate, I want to thank you for the effort you put into making videos to support growing data scientists.
I’ve been following your work since taking your machine learning course, and I’m impressed by your practical approach to applying AI.
