Web browser game development. An agent skill from sickn33/agentic-awesome-skills.
- Works in 7 steps: Framework Selection → WebGPU Adoption → Performance Principles → …
- Building HTML5/WebGL/WebGPU games
- SKILL.md covers 1. Framework Selection, 2. WebGPU Adoption, 3. Performance Principles and 4. Asset Strategy, plus 5 more sections
- Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
What it does
Web Games is an agent skill from sickn33/agentic-awesome-skills. Web browser game development. Framework selection (Phaser, PixiJS, Kaplay, Canvas/WebGL, Three.js, Babylon.js), hybrid DOM+canvas, WebGPU, optimization, PWA, audio unlock. Use when building HTML5/WebGL/WebGPU games or choosing a browser runtime.
Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Game Development, covering 3D graphics and WebGL and Game development. It works with Three.js. The repository describes itself as: AAS Core is the local, agent-first control plane for complete catalog discovery, agent-owned selection, stack validation, and planning, backed by 2,400+ agentic skills. Includes… The licence is MIT.
When your agent uses it
- Building HTML5/WebGL/WebGPU games
- Choosing a browser runtime
Example prompts
- “/web-games”
Workflow steps
7 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit ec02547. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Web Games loads about 1.1k tokens when it runs. Until then it costs about 64 tokens; SKILL.md has 428 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Web Browser Game Development
Framework selection and browser-specific principles. For stack choice details see
game-development/engine-selection.
1. Framework Selection
Decision Tree
What type of game?
│
├── 2D Game
│ ├── Full game engine features? → Phaser 4
│ ├── Fast prototype / jam? → Kaplay
│ ├── Raw rendering power? → PixiJS 8
│ └── Tiny / no dependency? → Raw Canvas / WebGL
│
├── 3D Game
│ ├── Full engine (physics, XR)? → Babylon.js
│ └── Rendering focused? → Three.js
│
├── Hybrid (DOM UI + canvas moments)
│ └── Custom shell + guest viewport
│ (Canvas/Kaplay/Phaser/Pixi inside a region/modal)
│
└── Narrative-first
└── Ink (inkjs) or Twine export + DOM hostComparison
| Framework | Type | Best For |
|---|---|---|
| Raw Canvas / WebGL | 2D / low-level | Small scope, full control |
| Kaplay | 2D toolkit | Rapid prototypes |
| Phaser 4 | 2D engine | Full game features |
| PixiJS 8 | 2D renderer | Rendering, custom systems |
| Three.js | 3D renderer | Visualizations, lightweight 3D |
| Babylon.js | 3D engine | Full engine, XR |
Hybrid shell + guest
Use when chrome is HTML (menus, inventories, text, dashboards) but bursts of play need a canvas:
- Mount guest in a container; pass context in.
- Run a local game loop in the guest.
- Return results (score, pass/fail); destroy guest (RAF, listeners, GL context as needed).
Do not let the guest own global app routing unless the product is a full-screen game.
2. WebGPU Adoption
Browser Support (2025)
| Browser | Support |
|---|---|
| Chrome | ✅ Since v113 |
| Edge | ✅ Since v113 |
| Firefox | ✅ Since v131 |
| Safari | ✅ Since 18.0 |
| Total | ~73% global |
Decision
- New GPU-heavy projects: Use WebGPU with WebGL fallback
- Broad legacy / simple 2D: Start with WebGL or Canvas 2D
- Feature detection: Check
navigator.gpu
3. Performance Principles
Browser Constraints
| Constraint | Strategy |
|---|---|
| No local file access | Asset bundling, CDN |
| Tab throttling | Pause when hidden (visibilitychange) |
| Mobile data limits | Compress assets |
| Audio autoplay | Require user interaction |
Optimization Priority
- Asset compression - KTX2, Draco, WebP
- Lazy loading - Load on demand
- Object pooling - Avoid GC
- Draw call batching - Reduce state changes
- Web Workers - Offload heavy computation
Show full SKILL.md (189 more words)Show less
4. Asset Strategy
| Type | Format |
|---|---|
| Textures | KTX2 + Basis Universal (or WebP/PNG for simple 2D) |
| Audio | WebM/Opus (fallback: MP3) |
| 3D Models | glTF + Draco/Meshopt |
| Phase | Load |
|---|---|
| Startup | Core assets, <2MB |
| Gameplay | Stream on demand |
| Background | Prefetch next level |
5. PWA for Games
Benefits: offline play, install, fullscreen, optional push. Requirements: service worker, web app manifest, HTTPS.
6. Audio Handling
- Create/resume
AudioContexton first click/tap - Prefer Web Audio API; pool sources; preload common SFX
- Compress with WebM/Opus when possible
7. Anti-Patterns
| ❌ Don't | ✅ Do |
|---|---|
| Load all assets upfront | Progressive loading |
| Ignore tab visibility | Pause when hidden |
| Block on audio load | Lazy load audio |
| Skip compression | Compress everything |
| Assume fast connection | Handle slow networks |
| Leave canvas engines running off-screen | Tear down guests |
Remember: Browser is the most accessible platform. Respect its constraints.
When to Use
Use when building HTML5/WebGL/WebGPU games, choosing a browser runtime, or wiring hybrid DOM+canvas guests.
Limitations
- Use this skill only when the task clearly matches the scope described above.
- Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
- Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
