web-games

web-games is a skill for Claude Code from DDS-Solutions/AI-TadPole-OS. It costs 20 tokens per session (902 once invoked), scanned A, a copy of web-games, MIT.

A guide to developing games that run in web browsers, covering game frameworks, graphics APIs, and browser performance.

In plain words
What is it for?
Selecting tools for 2D and 3D games, using Canvas, WebGL, or WebGPU, and planning browser support and progressive web app features.
Why use it?
It helps choose suitable browser game technology instead of treating every game as the same rendering problem.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

web-games scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

84% identical to web-games — 13 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Web Browser Game Development

Framework selection and browser-specific principles.


1. Framework Selection

Decision Tree

What type of game?
│
├── 2D Game
│   ├── Full game engine features? → Phaser
│   └── Raw rendering power? → PixiJS
│
├── 3D Game
│   ├── Full engine (physics, XR)? → Babylon.js
│   └── Rendering focused? → Three.js
│
└── Hybrid / Canvas
    └── Custom → Raw Canvas/WebGL

Comparison (2025)

Framework Type Best For
Phaser 4 2D Full game features
PixiJS 8 2D Rendering, UI
Three.js 3D Visualizations, lightweight
Babylon.js 7 3D Full engine, XR

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 projects: Use WebGPU with WebGL fallback
  • Legacy support: Start with WebGL
  • Feature detection: Check navigator.gpu

3. Performance Principles

Browser Constraints

Constraint Strategy
No local file access Asset bundling, CDN
Tab throttling Pause when hidden
Mobile data limits Compress assets
Audio autoplay Require user interaction

Optimization Priority

  1. Asset compression - KTX2, Draco, WebP
  2. Lazy loading - Load on demand
  3. Object pooling - Avoid GC
  4. Draw call batching - Reduce state changes
  5. Web Workers - Offload heavy computation

4. Asset Strategy

Compression Formats

Type Format
Textures KTX2 + Basis Universal
Audio WebM/Opus (fallback: MP3)
3D Models glTF + Draco/Meshopt

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
