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.

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.

1. Go to Settings > Capabilities
2. Enable Skills toggle
3. Browse available skills or upload custom skills
4. For Team/Enterprise: Admin must enable Skills organization-wide first
