Construct is a Fabric mod for Minecraft 1.21.11 that generates build-ready schematic data from in-game text prompts using Gemini AI. The mod adds a server command to request structures, tracks job progress, and keeps a short per-player history of recent requests. Players can set their API key from a client UI
Main features:
- /construct : starts an asynchronous generation request
- /history [limit]: shows recent generation jobs for the player
- /constructapikey: opens a client screen to save, clear, and sync API key
