This release turns Gemini AI Companion into a true structured Minecraft builder instead of a raw command generator.
- Structured voxel architect: The AI can now return a
build_planwith cuboids, single-block placements, palettes, rotations, and phasedsteps[]. - Terrain-aware planning: New
buildsitescanning gives the model real local terrain context before it builds. - Planner validation and repair: The build pipeline validates block IDs, block states, volume, coordinates, rotations, and support, then repairs common near-miss issues automatically.
- Phased construction: Larger builds can decompose into foundation, walls, roof, details, and follow-up passes.
- Safer special block handling: Better expansion and normalization for doors, beds, stairs, slabs, fences, panes, and walls.
- Support-aware execution: Floating plans can be repaired with support pillars, and obviously unsupported builds are rejected with useful retry feedback.
- Undo for structured builds:
/chat undocan now restore terrain and block-entity state after planner-driven builds.
- Gemini 3.1 Pro Preview is now the Pro target.
- Native structured output schema is applied to Gemini requests for more reliable JSON responses.
- Better loop control reduces repeated tool spam and pointless ASK/TOOL bouncing on simple build requests.
- API fallback handling now retries cleaner on transient Gemini failures.
You can now ask for things like:
build me a little oak house heremake a compact furnace shed next to mebuild a watchtower with a stone base and wood roof
and the mod will plan the structure, validate it, repair what it can, execute it safely, and preserve an undo path.
