What problem does it solve? Developing Decentraland SDK7 scenes requires knowing dozens of components, strict composite-first authoring rules, QuickJS sandbox constraints, and editor pitfalls like the Creator Hub overwriting hand-edited composite files. This Skill acts as the entry point that enforces correct agent behavior and routes every task to the right topic-specific guidance. ## Core Features & Use Cases - Agent behavioral guidelines: Requires user confirmation before changing parcel layouts, fetching external assets, adding a multiplayer server, or falling back from Blender MCP to headless Blender. - Composite-first rule enforcement: Ensures static entities live in assets/scene/main.composite while TypeScript handles only dynamic behavior, with safe edit-mode procedures for existing composites. - Skill index and routing: Maps user requests to 25+ individual topic skills covering 3D models, animations, UI, multiplayer sync, particles, deployment, and SDK6-to-SDK7 migration. - Use Case: A user asks to add a glowing portal with a click interaction to their scene. The Skill routes to add-3d-models, advanced-rendering, and add-interactivity, while confirming before downloading any external GLB model. ## Quick Start Ask the agent to build a Decentraland SDK7 scene feature, such as adding an interactive door with a tween animation, and it will load the relevant topic skills automatically.
