Quick Start
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.
What are Skills?
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.

Skills vs MCP vs System Prompts
Confused about when to use Skills vs other Claude customization methods? Here's the breakdown:
| Feature | Skills | MCP Servers | System Prompts |
|---|---|---|---|
| Purpose | Task-specific workflows | External tool integration | General behavior modification |
| Setup | Git clone to ~/.claude/skills/ | Install & configure MCP server | Edit CLAUDE.md in project |
| Activation | Automatic (context-aware) | Explicit tool calls | Always active |
| Best For | TDD, debugging, git workflows | APIs, databases, file systems | Project conventions, style guides |
| Portability | Cross-platform (CLI, web, API) | Platform-dependent | Project-specific |
| Token Cost | 30-50 until loaded | Per-call | Always consuming tokens |
| Examples | test-driven-development | Weather API, GitHub integration | "Use TypeScript strict mode" |
When to use what:
- ✅ Skills → Repeatable workflows (TDD, debugging, code review)
- ✅ MCP → External data/tools (APIs, search, databases)
- ✅ System Prompts → Project-specific rules and conventions

ls ~/.claude/skills/
Can I use multiple skills at once?
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.
Do skills work on all platforms?
Yes! Skills use the same format across Claude Code CLI, Claude.ai, and the Claude API. Install once, use everywhere.
How do I update skills?
cd ~/.claude/skills/skill-name
git pull origin main
Can I create my own skills?
Absolutely! Check out the skill-creator skill and our Contributing Guide for best practices.
Do skills consume tokens?
Minimal! Each skill uses only 30-50 tokens until Claude loads it. Once loaded, only relevant portions are used.
