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
