What problem does it solve? When working with a large Unity automation toolkit, it is hard to know which module handles a given task, whether that module needs user approval under the current operating mode, and what the exact skill signatures are. This index catalogs every functional REST module and advisory design module so you can route tasks correctly. ## Core Features & Use Cases - Module Catalog: Lists 50+ functional modules (gameobject, component, prefab, scene, shadergraph, netcode, yooasset, dotween, and more) with batch support and mode labels (SA / FA / Mixed / auto-forbidden). - Advisory Design Modules: Provides design-only guidance modules such as architecture, patterns, unitask-design, addressables-design, and yaml-editing for planning and review tasks. - Mode & Schema Routing: Explains Approval/Auto/Bypass operating modes, the batch-first rule for multi-object edits, and the <module>_<action> naming convention verified against GET /skills/schema. - Use Case: A user asks to set up XR grab interactions; you consult the index, find the xr module (FA mode), load its SKILL.md and API reference, then call xr_add_grab_interactable with verified parameters. ## Quick Start Ask which Unity module handles a task, for example request the module list and the right module for editing prefabs in Auto mode.
