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.

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 | $0.00099 | $0.01517 |
| Opus 5 | $0.00049 | $0.00758 |
| Sonnet 5 | $0.00020 | $0.00303 |
| Haiku 4.5 | $0.00010 | $0.00152 |
Grade A, and why
pixijs-core-concepts 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 13d 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.

How it starts
The opening of the file, as written. The whole thing — 132 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Foundational model for how PixiJS v8 gets pixels on the screen: the renderer decides which GPU backend to use, the render loop drives per-frame work, and the environment layer adapts the library to browser, Web Worker, or SSR contexts. For the scene graph itself (Containers, transforms, destroy), see pixijs-scene-core-concepts.
Quick Start
console.log(app.renderer.name); // 'webgl' | 'webgpu' | 'canvas'
app.ticker.add((ticker) => {
sprite.rotation += 0.01 * ticker.deltaTime;
});
const tex = app.renderer.extract.texture({ target: app.stage });
app.renderer.render({ container: app.stage });
app.renderer is the WebGLRenderer, WebGPURenderer, or CanvasRenderer chosen by autoDetectRenderer. The TickerPlugin drives renderer.render() automatically; call it manually only with autoStart: false. Backend selection happens in Application.init({ preference }); see pixijs-application for setup.

Topics
| Topic | Reference | When |
|---|---|---|
| Choosing a backend | references/renderers.md | Preference forms, per-renderer options, systems and pipes |
| Per-frame execution | references/render-loop.md | Priority order, time units, manual rendering |
For deep dives into any single topic, open the corresponding reference file. Non-browser targets (DOMAdapter, WebWorkerAdapter, custom adapters, strict CSP) are covered in the pixijs-environments skill.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

pixijs-core-concepts is a skill published in the GitHub repository pixijs/pixijs-skills (330 stars, last pushed 3mo ago), licensed MIT. It adds 99 tokens to every session and 1,517 once invoked, about $0.0005 per session on Opus 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.
