Agent-friendly Go CLI for the official Fortnite Ecosystem v1 Data API, plus a companion agent skill (fortnite-islands).
Queries Fortnite island (Creative / UEFN) metadata and engagement metrics: peak CCU, plays, unique players, retention, favorites, minutes played, recommendations, average minutes per player. It does not cover player stats, matches, cosmetics, shop, or BR stats — those are not part of the Ecosystem API.

Copy skill/fortnite-islands/ into your agent's skills directory. Installation paths vary by agent — see your agent's docs for where skills live. After that, ask your agent things like "What are the top 10 Fortnite islands by peak CCU right now?" and it will use the CLI.
