Perform a non-destructive cross-artifact consistency and quality analysis across spec.md, plan.md, and tasks.md after task generation.

Generate a custom checklist for the current feature based on user requirements.

Identify underspecified areas in the current feature spec by asking up to 5 highly targeted clarification questions and encoding answers back into the spec.

Create or update the project constitution from interactive or provided principle inputs, ensuring all dependent templates stay in sync.

Execute the implementation plan by processing and executing all tasks defined in tasks.md

Execute the implementation planning workflow using the plan template to generate design artifacts.

Create or update the feature specification from a natural language feature description.

Generate an actionable, dependency-ordered tasks.md for the feature based on available design artifacts.

Use this skill when an AI agent needs to inspect, verify, or debug a live Vite app by running temporary snippets inside the browser page and reading browser logs. Use for client state after interactions, imported app modules, DOM state, human-like input, canvas/WebGL/Three.js state, screenshots, videos, WebXR/Three.js XR with IWER, and runtime-only behavior without editing app files.

Build, modify, debug, or validate XR, AR, VR, spatial interaction, pointer, controller, hand-tracking, hit-test, teleportation, layer, anchor, uikit, and handle-based React Three Fiber apps using @react-three/xr, @react-three/handle, and @react-three/uikit. Use when working on immersive WebXR experiences, R3F-to-XR conversions, XR games, spatial tools, or XR validation/test harnesses.

Build, modify, debug, or publish VIVERSE-ready web games and 3D apps with Three.js, React Three Fiber, @pmndrs/viverse, @react-three/viverse, VIVERSE SDK integrations, character controllers, physics, avatars, actions, animations, AR, or VR.

Use this skill when an AI agent needs to inspect, verify, debug, or profile a live Vite app by running temporary snippets inside the browser page and reading browser logs or captured artifacts. Use for client state after interactions, imported app modules, DOM state, human-like input, canvas/WebGL/Three.js state, screenshots, videos, CPU/network/performance/heap analysis, WebXR/Three.js XR with IWER, and runtime-only behavior without editing app files.

Real-time ECS state management for TypeScript and React. Use when the user mentions koota, ECS, entities, traits, queries, or building data-oriented applications.

Build, explain, and modify @react-three/start apps that use file-based React Three Fiber scene and DOM composition. Use when working in a react-three-start project, when the user mentions @react-three/start, react-three-start, R3F app structure, .scene.tsx/.dom.tsx files, Scene/Dom slots, wrappers, start.config.ts, or the react-three-start/r3s CLI.
