 Claude Skills are installable knowledge packages that extend Claude's capabilities for specific domains. A skill is a `.skill` file — a bundled archive containing a `SKILL.md` instruction file and optional reference materials — that you upload to Claude once and use across all your conversations.
 
 Once installed, a skill activates **automatically** when your conversation touches its topic area. You don't need to invoke it by name or use special commands. Claude simply becomes a deeper expert in that domain for the duration of your session.
