Phaser is an open-source 2D game framework for creating HTML5 games that run in desktop and mobile web browsers with Canvas or WebGL rendering. JavaScript and TypeScript developers use it to build browser games and games distributed through platforms such as YouTube, Discord, Reddit, and Twitch. The catalogue skills support coding-agent workflows for Phaser projects.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 1 finding, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00056 | $0.05176 |
| Opus 5.5 | $0.00022 | $0.02070 |
| Sonnet 5.5 | $0.00011 | $0.01035 |
| Haiku 4.5 | $0.00006 | $0.00518 |
Grade A, and why
audio-and-sound 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 1mo 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.

The opening of the file, as written. The whole thing — 454 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Audio and Sound
Phaser provides a unified Sound system via
this.sound(a SoundManager) that abstracts over Web Audio API and HTML5 Audio. It handles loading, playback, volume, panning, looping, markers, audio sprites, spatial audio, and browser autoplay-policy unlocking.
Key source paths: src/sound/BaseSoundManager.js, src/sound/BaseSound.js, src/sound/webaudio/, src/sound/html5/, src/sound/SoundManagerCreator.js, src/sound/events/, src/sound/typedefs/
Related skills: ../loading-assets/SKILL.md, ../game-setup-and-config/SKILL.md
Quick Start
class GameScene extends Phaser.Scene {
preload() {
this.load.audio('bgm', 'assets/music.mp3');
this.load.audio('coin', ['assets/coin.ogg', 'assets/coin.mp3']);
}
create() {
// Fire-and-forget (auto-destroys when complete)
this.sound.play('coin');
// Retained reference for ongoing control
this.music = this.sound.add('bgm', { loop: true, volume: 0.5 });
this.music.play();
}
}
Assets loaded via this.load.audio() in preload() are ready by the time create() runs. Provide an array of URLs for cross-browser format fallback.
Core Concepts
WebAudio vs HTML5 Audio
Phaser auto-selects the best backend via SoundManagerCreator.create():
- If
config.audio.noAudiois true, or the device supports neither Web Audio nor HTML5 Audio, a NoAudioSoundManager is created (all calls are no-ops). - If the device supports Web Audio and
config.audio.disableWebAudiois not true, a WebAudioSoundManager is created (preferred). - Otherwise, an HTML5AudioSoundManager is created as fallback.
WebAudio advantages: precise timing, gapless looping, stereo panning (StereoPannerNode), spatial audio (PannerNode), per-sound gain nodes, decodeAudio() for runtime decoding.
HTML5 Audio limitations: no spatial audio, no real stereo panning (pan fires events but no audible effect), less precise looping, requires instances count at load time for simultaneous playback.
What this file has done since we first saw it
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.

audio-and-sound is a skill published in the GitHub repository phaserjs/phaser (40,529 stars, last pushed 2mo ago), licensed MIT. It adds 56 tokens to every session and 5,176 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
