Claude Code / Claude Desktop 1. Create a folder named after the skill inside your skills directory: - Claude Code: `~/.claude/skills/<skill-name>/` - A project-local skill: `<project>/.claude/skills/<skill-name>/` 2. Save the text below as `SKILL.md` in that folder, keeping the `---` frontmatter block at the top — the `name` and `description` fields are what make the skill discoverable. 3. Restart Claude Code, or run `/skills` to confirm it is listed. The skill loads only when its `description` matches what you are doing, so a precise description matters more than a long body.
