What problem does it solve? VRChat Avatar Unity projects accumulate menus, parameters, Animator controllers, and third-party providers (FaceEmo, lilycalInventory, Modular Avatar) whose actual behavior is hard to trace. This Skill audits an avatar from the player-visible Expressions Menu down to exact model bindings, producing durable, evidence-labeled project documentation instead of guesswork. ## Core Features & Use Cases - Toolchain confirmation gate: Detects installed packages and provider components, then lets the user confirm tool roles before any audit or mutation. - Menu-to-model tracing: Follows each menu control through parameters, Animators, and providers to exact objects, materials, BlendShapes, PhysBones, and Contacts. - Evidence ladder: Labels every conclusion as STATIC_SOURCE, UNITY_RESOLVED, PROVIDER_PREVIEW, NDMF_BUILT, SDK_BUILD, CLIENT_RUNTIME, or UPLOAD_CONFIRMED, and marks unrun layers NOT_RUN or BUILD_REQUIRED. - Use Case: After importing a new clothing prefab, ask the Skill to trace each wardrobe toggle to its actual model objects, record the parameter delta, and refresh the audit documents. ## Quick Start Ask the agent to inspect this VRChat Avatar project, confirm the toolchain selection first, then audit the complete player menu and generate evidence-labeled documentation.
