What is a Claude Skill?
Teach Claude once, use it forever
A Skill is a folder with instructions that teaches Claude how to handle a specific task. Instead of repeating yourself in every chat, you teach Claude once and reuse that knowledge forever. Think of it as building a personal assistant that remembers exactly how you want things done.
The Kitchen Analogy
MCP Provides the Kitchen
Access to tools, ingredients, and equipment — connects Claude to Notion, Asana, Linear, and more.
Skills Provide the Recipes
Step-by-step instructions for creating something valuable — the workflow knowledge.
A Skill without MCP tools is like a recipe without a kitchen — it still teaches Claude how to think about a task. MCP without Skills is like a kitchen without recipes — powerful, but users do not know what to cook.
Why Skills Matter
| Aspect | Without Skill | With Skill |
|---|---|---|
| Setup | Explain everything each time | Automatic execution |
| Messages | 15 back-and-forth | 2 clarifying questions |
| API failures | 3 failed calls needing retries | 0 failed calls |
| Tokens used | 12,000 | 6,000 |
Key Insight
Without a Skill, you explain the same task in every chat. With a Skill, Claude knows exactly what to do. You save time and get consistent, high-quality results every time.
Remember
A Claude Skill is a way to teach Claude once and benefit forever. It consists of a folder with a SKILL.md file at its core, optionally supported by scripts, templates, and examples.
