Add a skill to Claude in about a minute.

In Claude (web, desktop or mobile app)

1. Download the ZIP from the link in your email. Don't unzip it: Claude wants the ZIP as it is.
2. Open Skills in Claude. On claude.ai or the desktop app, open Customize, then Skills. On some versions it's under Settings, Capabilities, Skills.
3. Upload it. Click +, choose Create skill, then Upload a skill, and pick the ZIP. One ZIP per upload.
4. Check it's on. The skill should show as enabled. Skills work on any Claude plan, including the free one. Just turn on code execution in Settings, Capabilities.
5. Start a new chat and ask about your team, for example "Help me set my lineup this week." Claude loads the skill on its own when it's relevant.

In Claude Code

1. Unzip the file into your skills folder: unzip FILE.zip -d ~/.claude/skills/
2. Start Claude Code and ask about your team. The skill loads when it's relevant.

Using it well

• Give it your league settings the first time: scoring, roster slots, league size and platform. It will ask if you don't.
• Turn on web search in Claude so it can check injuries, lineups and news. Or paste the latest reports in.
• Paste your roster or matchup straight from Yahoo, ESPN, Sleeper, FPL or wherever you play.

Troubleshooting

I don't see Skills in Claude

Skills work on any Claude plan, including the free one, with code execution turned on in Settings, Capabilities. On Team and Enterprise, an admin may need to allow skills and code execution for your organization.

The upload fails

Upload the ZIP exactly as downloaded. If your computer unzipped it automatically, zip the folder again (the folder that contains SKILL.md) and upload that.

Claude isn't using the skill

Check the skill is toggled on and code execution is enabled, then start a new chat. Mentioning your sport and league usually triggers it.
