Awesome Claude Skills

A curated list of awesome Claude Skills, resources, and tools for customizing Claude AI workflows

**Claude Skills** teach Claude how to **perform tasks in a repeatable way**

They are specialized folders containing instructions, scripts, and resources that Claude dynamically discovers and loads when relevant to tasks.

How Skills Work

Skills employ a **progressive disclosure architecture** for efficiency:

1. Metadata loading (~100 tokens): Claude scans available Skills to identify relevant matches
2. Full instructions (<5k tokens): Load when Claude determines the Skill applies
3. Bundled resources: Files and executable code load only as needed

This design allows multiple Skills to remain available without overwhelming Claude's context window.
