🤔 What Are Claude Skills?

A Claude Skill is a portable, copy-paste-ready instruction file that gives Claude a specialized capability. Unlike generic prompt collections, each skill is:

Feature	Description
🎯 Purpose-built	Designed for a specific real-world task, not a toy demo
📋 Structured	Uses the proven Role → Goal → Constraints → Output contract format
🧪 Tested	Every skill includes example inputs/outputs so you know what to expect
🔌 Plug-and-play	Works with Claude.ai, Claude API, Claude Code (CLAUDE.md), and any Claude-powered tool
🏷️ Tagged	Difficulty level, estimated token usage, and compatibility info included

⚡ Quick Start

Method 1: Claude.ai (Recommended for beginners)

1. Browse the Skill Catalog below
2. Open the skill file (e.g., skills/developer/code-reviewer.md)
3. Copy the content inside the <system_prompt> tags
4. Paste it into Claude.ai → Project Knowledge or Custom Instructions
5. Start chatting — Claude now has that skill!

Method 2: Claude Code (CLAUDE.md)

1. Copy the skill file to your project root as CLAUDE.md (or append to an existing one)
2. Run claude in your terminal — it auto-reads the file
3. Claude Code now operates with that specialized skill

Method 3: API / SDK

import anthropic

# Load the skill
with open("skills/developer/code-reviewer.md") as f:
    skill = f.read()

client = anthropic.Anthropic()
message = client.messages.create(
    model="claude-sonnet-4-20250514",
    max_tokens=4096,
    system=skill,  # ← The skill becomes the system prompt
    messages=[{"role": "user", "content": "Review this pull request: ..."}]
)
