- Gen Agent Trust Hubpass
The skill is generally safe and provides detailed instructions for building 3D geometry and assets in Roblox Studio. It utilizes the Model Context Protocol (MCP) and Luau for automation and includes references to official Roblox documentation and community guides. A minor security surface was identified where the agent could potentially ingest malicious instructions hidden in object names or properties within the Roblox workspace it is inspecting.

Roblox Building
When to Load
Load for geometry, props, maps, and spatial onboarding via MCP or Luau.
Quick Reference
MCP Build Mode
- Inspect Studio, Workspace, and existing assets.
- Name the root, origin, dimensions, and assets.
- Build in phases; read back each batch.
- Verify the tree, view, and traversal.
Asset Choice
- Search project assets and Toolbox before generating. Check type, creator, price, scripts, and fit.
- Before paid or cross-owner insertion, disclose creator, ID, price, and rights. Inspect scripts and dependencies; remove unneeded code and test in scene. See
roblox-security. - MCP:
generate_procedural_model,generate_mesh,generate_material. - Studio Assistant previews models, restyles textures, and segments imported meshes. These aren't confirmed MCP tools; see full reference.
- Check mesh bounds, collision, PBR, and quality levels.
- Use permitted images; wait for jobs to finish.
EditableImage/EditableMeshhave permission and memory limits.- Use native Parts/CSG when reuse or generation is unsuitable.
Player Scale
Player ~5 studs | Door 4w×7h | Ceiling 10-14 | Counter 3.5-4 | Seat 1.5 | Path 6+
Spatial Rules
- Name dimensions; offset sub-parts from anchor CFrames, not guessed world coordinates.
- Snap to 0.125/0.25/0.5 studs.
- Build complex CSG near origin, then
PivotTothe destination. - Set anchoring, collision, shadows, color, and material explicitly.
Acceptance
Prop: named model, pivot, scale, bounds, materials, collision, anchoring, no loose parts, asset provenance. Map: root/origin, zones, landmarks, spawns/return paths, path widths, traversal, and bounds checks excluding Baseplate/Terrain/SpawnLocation. Evidence: readback, a view when supported, and playtest results.
Anti-Patterns
Guessing coordinates | unanchored or duplicate parts | hardcoded world positions | silent CSG failure | oversized batches | claims without readback
Details: references/full.md covers maps, validation, and assets.
