🚀 Quick Start

Use a Skill in Claude.ai

1. Open Claude.ai and start a new conversation
2. Copy the contents of any skills//SKILL.md file
3. Paste it at the start of your conversation or as a system prompt
4. Claude is now an expert — start prompting

Use a Skill via API

import anthropic

with open("skills/pdf/SKILL.md") as f:
    skill = f.read()

client = anthropic.Anthropic()
response = client.messages.create(
    model="claude-opus-4-6",
    max_tokens=4096,
    system=skill,
    messages=[{"role": "user", "content": "Merge these two PDFs and add a watermark"}]
)
print(response.content[0].text)

Use a Skill in Claude Code

# Add to your CLAUDE.md or paste into any conversation
cat skills/code-reviewer/SKILL.md

> [!TIP] > Pro tip: Combine multiple skills by concatenating their SKILL.md files — Claude handles multi-skill contexts gracefully.
