Skills library

A skill is a folder with a SKILL.md file: a name, a one-line description, then instructions in plain English. Install one and every crewmate can load it. Our own skills come first, then skills from other people, sorted by the work they do.

8 of our own skills, and 41 from the community across 8 domains.

How to install a skill

Each skill goes in its own folder under ~/.claude/skills/, in a file called SKILL.md. Claude Code picks up a new skill without a restart; if the skills folder did not exist when the session started, type /reload-skills or start a new session.

$mkdir -p ~/.claude/skills/claim-check && mv ~/Downloads/claim-check.SKILL.md ~/.claude/skills/claim-check/SKILL.md

Before you install someone else's skill

  • Read the SKILL.md and any scripts before you install it. Your crew will follow those instructions with your permissions.
  • Skip a skill that asks for passwords, API keys or payment details, or that downloads and runs a program you cannot read.
  • Install from the author's own repository, not from a copy someone re-uploaded.
  • A skill can change after we checked it. If it looks different from the description here, read it again before you update.
