Skills9

game-playtestskills/game-playtest/SKILL.md

Run browser-game playtests and frontend QA. Use when the user asks for smoke tests, screenshot-based verification, browser automation, HUD or overlay review, or structured issue-finding in a browser game.

game-studioskills/game-studio/SKILL.md

Route early browser-game work. Use when the user needs stack selection and workflow planning across design, implementation, assets, and playtesting before moving to a specialist skill.

game-ui-frontendskills/game-ui-frontend/SKILL.md

Design UI surfaces for browser games. Use when the user asks for HUDs, menus, overlays, responsive layouts, or visual direction that must protect the playfield.

phaser-2d-gameskills/phaser-2d-game/SKILL.md

Implement 2D browser games with Phaser. Use when the user wants a Phaser, TypeScript, and Vite stack for scenes, gameplay systems, cameras, sprite animation, and DOM-overlay HUD patterns.

react-three-fiber-gameskills/react-three-fiber-game/SKILL.md

Build React-hosted 3D browser games with React Three Fiber. Use when the user wants pmndrs-based scene composition, shared React state, and 3D HUD integration inside a React app.

sprite-pipelineskills/sprite-pipeline/SKILL.md

Generate and normalize 2D sprite animations. Use when the user asks for full-strip generation from approved source frames, consistent anchor and scale normalization, or preview assets for browser-game animation.

three-webgl-gameskills/three-webgl-game/SKILL.md

Implement browser-game runtimes with plain Three.js. Use when the user wants imperative scene control in TypeScript or Vite with GLB assets, loaders, physics, and low-level WebGL debugging.

web-3d-asset-pipelineskills/web-3d-asset-pipeline/SKILL.md

Prepare and optimize browser-game 3D assets. Use when the user asks for GLB or glTF shipping work, including Blender cleanup and export, collision or LOD setup, compression, texture packaging, and runtime validation.

web-game-foundationsskills/web-game-foundations/SKILL.md

Set browser-game architecture before implementation. Use when the user needs engine choice, simulation and render boundaries, input model, asset organization, or save/debug/performance strategy.
