Claude Code has native skill support built in. Skills placed in the correct directory are auto-discovered and available as slash commands across all your projects.

1. 1

   Download your skill file

   Go to your account page and click the Download button next to any skill you own. The file downloads as slug-name.md (e.g. atomic-habits.md).

2. 2

   Create the skill directory

   Open your terminal and create a subdirectory for the skill inside ~/.claude/skills/. Replace "atomic-habits" with your skill's slug:

   mkdir -p ~/.claude/skills/atomic-habits
3. 3

   Move and rename the file

   Move the downloaded file into the directory, renaming it to SKILL.md:

   mv ~/Downloads/atomic-habits.md ~/.claude/skills/atomic-habits/SKILL.md
