Install
A skill is a folder: SKILL.md plus reference files the agent loads when it needs them. Only Claude Code runs skills natively. Every other tool below uses the same files with a small manual step: usable, just not the same thing.
Coding agents
Swipe sideways or use the tabs above to switch agents.
Claude Code
Recommended. Native skill support.
- Unzip the folder
- Move it into ~/.claude/skills/
- Restart Claude Code
- Type /command-name
Note: Skills in ~/.claude/skills/ are available in every project.
unzip product-led-onboarding.zip -d ~/.claude/skills/
Other tools
Swipe sideways or use the tabs above to switch tools.
Claude Chat
Persistent across every conversation in a project.
- Unzip the folder
- Create a project in Claude
- Upload SKILL.md and the reference files into the project knowledge
- Ask for the skill by name in any chat inside that project
Warning: The knowledge base caps out at 200K tokens. One project per skill works better than one project holding everything.
When it doesn't work
- The skill doesn't show up in Claude Code
- Two causes, in this order: the folder isn't directly inside
~/.claude/skills/, or Claude Code wasn't restarted after you moved it. - The ZIP won't extract
- Use the shell command above instead of the desktop unarchiver. The archive contains a folder, so it will never scatter files into your current directory.
- The download link is dead
- Email links last seven days. Your bookshelf doesn't expire, enter your purchase email and get a fresh link.
- The email never arrived
- Same answer: /my-bookshelf delivers everything that email owns, again.
Wondering what SKILL.md is, where the format comes from and why a skill is a folder instead of a prompt? The FAQ answers that.
Still Not Working?
Reply to your delivery email. I read those. Or pull a fresh link yourself.
