Implement and optimize browser games using Phaser, Three.js, React Three Fiber, Babylon.js, or PlayCanvas with responsive input, asset loading, rendering, and browser playtests. Use for JavaScript or TypeScript game projects.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Web game development ## Select the existing engine Read `package.json`, source imports, renderer initialization, and asset loaders before editing. Preserve the chosen engine unless the user requests a migration. - Phaser: scene-driven 2D games, sprites, tilemaps, cameras, and arcade or matter physics. - Three.js: imperative 3D scene, camera, renderer, loaders, and render-loop control. - React Three Fiber: React-owned composition around Three.js with explicit per-frame boundaries. - Babylon.js: engine-managed 3D scenes, loaders, physics, GUI, and WebGPU or WebGL paths. - PlayCanvas: component and entity workflows using the project's selected editor or engine package. ## Implementation rules - Use Bun for dependency and script commands. - Keep simulation state separate from rendering objects and DOM UI. - Map keyboard, pointer, touch, and controller input into explicit game actions. - Handle resize, device pixel ratio, pause, visibility changes, audio unlock, and WebGL context loss. - Keep text-heavy HUD and menus accessible and responsive. - Bound texture resolution, geometry, particles, post-processing, and retained resources. …

How to install
mdr add metaspartan/cybara/web-game-development@sha256:628611223935ef57The line at the top of this page pins the label git:20260902.14dbf87, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
