WorldPrompt

A tool for Minecraft builders to invoke AI agents who are following your building styles and patterns, letting you automate in the background whatever part of your project you want. Use it to fill your empty buildings with details or spawn large-scale structures to decorate whole selected regions. The agents will follow your specs surgically, use lecterns to add more context. Make sure to prompt well and to use the right AI models!

Requires installing a special external program.

🎮 Command guide

All commands start with /wp (alias /worldprompt). The flow is: select → prompt → keep, undo or rebuild.

1. Select an area

Selections are outlined with particles. The AI never builds outside the selection, so leave room above the ground. A selection is limited to 2,000,000 blocks by default (server setting maxSelectionBlocks, 4,000,000 at most).

2. Describe your build

The AI sees the existing blocks, so you can edit builds as well as create them: "turn this hill into a terraced vineyard", "add a second floor to this house".

3. Manage jobs

Several jobs can run at once if their selections don't overlap. Undo and rebuild history lasts until the server stops, and the undo depth (16) is the maxUndoEdits server setting.

Room-by-room instructions with lecterns

Put a lectern with a prompt book in any area of the selection to give that area its own instructions. A prompt book is a book titled or anvil-renamed prompt, or one whose text starts with prompt, for example Prompt: kitchen with stone counters. Then run /wp prompt with the overall request as usual. The lecterns stay in place unless you say otherwise. Limits: 64 lecterns, 4,000 characters per book, 16,000 in total.

Who can use what

• Everyone: pos1, pos2, select, jobs, cancel, book, delay, info.
• Operators only (by default): prompt, undo, rebuild.

Permission mods such as LuckPerms can override each command through worldprompt.command.<name>, e.g. /lp group builder permission set worldprompt.command.prompt true. Every prompt uses the Core operator's subscription, so grant prompt carefully. Details: permissions.
