Key points
- •A Skill is a packaged, reusable procedure — defined once, reused forever — the AI equivalent of an operating manual
- •The book's 5-step build process: identify a recurring workflow, create a skill folder + skill.md, write frontmatter + body, add supporting resources, zip and upload
- •Claude Desktop includes a 'Skill Creator' skill — a skill that helps you build skills
- •Skills don't replace Projects (workspace organization), MCP (tool/service connections), or Subagents (delegated reasoning) — they complement all three
- •MCP gives the ABILITY to use a tool; a Skill tells the agent HOW and WHEN to use it consistently for a specific recurring workflow
