Get your first skill running in 30 seconds:

# 1. Install obra's superpowers collection (20+ battle-tested skills)
git clone https://github.com/obra/superpowers ~/.claude/skills/superpowers

# 2. Try test-driven-development skill
# In Claude Code, just say: "Let's use TDD to build a user authentication system"
# Claude will automatically load the TDD skill and guide you through RED-GREEN-REFACTOR!

That's it! Skills load automatically when relevant. No configuration needed.

Agent Skills are modular capabilities that extend Claude's functionality through organized folders containing instructions, scripts, and resources. Each skill teaches Claude how to perform specialized tasks in a repeatable, standardized way.

Key benefits:

• Efficient: Skills use only 30-50 tokens until loaded
• Portable: Works across Claude Code CLI, Claude.ai, and API
• Composable: Stack multiple skills together
• Context-aware: Claude automatically identifies relevant skills

Skills are available on Claude Pro, Max, Team, and Enterprise plans with code execution enabled.

Start with these top 10 essential skills:

# Linux/macOS
mkdir -p ~/.claude/skills
git clone https://github.com/owner/skill-name ~/.claude/skills/skill-name

# Windows (PowerShell)
mkdir $env:USERPROFILE\.claude\skills
git clone https://github.com/owner/skill-name $env:USERPROFILE\.claude\skills\skill-name

Pro tip: Clone entire skill collections like obra/superpowers to get 20+ skills at once!

1. Create a folder in ~/.claude/skills/
2. Add a SKILL.md file with YAML frontmatter and instructions
3. (Optional) Include supporting scripts and resources

Verify installation:

# Check if skill is loaded
ls ~/.claude/skills/

# Skills load automatically - just start using Claude!

Looking for curated skill bundles? Start with these collections:

Skills load automatically when Claude detects they're relevant. You'll see Claude using skill-specific patterns (like RED-GREEN-REFACTOR for TDD). To check installed skills:

ls ~/.claude/skills/

Yes! Skills are composable. Claude automatically loads and coordinates multiple skills as needed. For example, you might use test-driven-development + systematic-debugging + using-git-worktrees simultaneously.

Yes! Skills use the same format across Claude Code CLI, Claude.ai, and the Claude API. Install once, use everywhere.

cd ~/.claude/skills/skill-name
git pull origin main

Absolutely! Check out the skill-creator skill and our Contributing Guide for best practices.

Minimal! Each skill uses only 30-50 tokens until Claude loads it. Once loaded, only relevant portions are used.

See the comparison table above. TL;DR: Skills for workflows, MCP for external tools.
