Agent Skills: Claude Code, Cursor and MCP in Practice

About this course

Typing prompts and hoping for the best is no longer enough. The developers getting real leverage from Claude Code, Cursor, and other AI coding tools in 2026 are the ones who have learned how to teach their AI — not just talk to it.

Agent skills are the mechanism that makes this possible. They are portable, reusable instruction packages that transform a general-purpose AI assistant into a specialist that knows your project structure, follows your team's conventions, can generate a polished PowerPoint or fill a PDF form on demand, and can reach out to external services via the Model Context Protocol without you writing a single prompt from scratch.

In just five months — from October 2025 to March 2026 — the agent skills ecosystem went from zero to over 350,000 published skills, with Anthropic's official repository alone reaching nearly 100,000 GitHub stars. This is not a niche topic. This is the new foundation of professional AI-assisted development.

This course puts you ahead of that curve — fast.

What this course covers

You will master three interconnected ecosystems that work together to supercharge your AI coding workflow:

• Claude Code Skills — the SKILL md format

You'll learn how the SKILL md format works from the ground up: the YAML frontmatter fields that control when and how a skill is triggered, the progressive disclosure architecture that keeps your context window lean even when dozens of skills are installed, and the three skill architecture patterns — Pure Markdown for lightweight guidance, Scripts + Markdown for deterministic processing, and MCP Integration for multi-service orchestration.

You'll build a commit message skill, a code review skill, and a document generation skill — then publish your own skill to a public GitHub repository and list it on the skills sh marketplace.
