A bulleted imperative like {match} tells the agent to never reveal, disclose, or mention something to the user. Used adversarially it can instruct the agent to hide its tool calls or lie about what it did — stripping the transparency a user relies on to trust the agent.

The primary manifest — the file an agent reads to learn what this artifact does.
NEVER pass options to the `Application` constructor — always use `await app.init()`.
// WRONG (deprecated, triggers warning in v8)
const app = new Application({ width: 800 });
// RIGHT
const app = new Application();
await app.init({ width: 800, height: 600 });NEVER use `app.view` — it was renamed to `app.canvas`.
// WRONG
document.body.appendChild(app.view);
// RIGHT
document.body.appendChild(app.canvas);NEVER use `Texture.from(url)` to load a URL that hasn't been loaded yet — load through `Assets` first.
// WRONG — will return empty texture if not preloaded
const tex = Texture.from('https://example.com/sprite.png');
// RIGHT
await Assets.load('https://example.com/sprite.png');
const tex = Texture.from('https://example.com/sprite.png');
// Or simply:
const tex = await Assets.load<Texture>('sprite.png');NEVER use the v7 Graphics API (beginFill / drawRect / endFill) — v8 changed the order.
// WRONG (v7 style)
g.beginFill(0xff0000).drawRect(0, 0, 100, 100).endFill();
// RIGHT (v8 style: shape first, then fill/stroke)
g.rect(0, 0, 100, 100).fill(0xff0000);NEVER add children to leaf nodes (Sprite, Graphics, Text) — only `Container` accepts children.
// WRONG
const sprite = new Sprite(texture);
sprite.addChild(otherSprite); // deprecated / will warn
// RIGHT
const container = new Container();
container.addChild(sprite);
container.addChild(otherSprite);NEVER use `DisplayObject` — it was removed. Everything is a `Container`.
NEVER use `container.name` — it was renamed to `container.label`.
NEVER use `SCALE_MODES.NEAREST` enum — use the string `'nearest'` instead.
NEVER use `container.cacheAsBitmap = true` — call `container.cacheAsTexture(true)` instead.
NEVER use `container.getBounds()` expecting a `Rectangle` — v8 returns a `Bounds` object; use `.rectangle`.
const rect = container.getBounds().rectangle;NEVER use `Ticker.shared.add(dt => ...)` expecting delta time — the callback now receives the Ticker instance.
// WRONG
Ticker.shared.add((dt) => {
sprite.x += dt;
});
// RIGHT
Ticker.shared.add((ticker) => {
sprite.x += ticker.deltaTime;
});NEVER import from sub-packages like `@pixi/sprite` — v8 uses a single package.
// WRONG
import { Sprite } from '@pixi/sprite';
// RIGHT
import { Sprite } from 'pixi.js';NEVER use `utils.isMobile` — import directly.
// WRONG
import { utils } from 'pixi.js';
utils.isMobile.any();
// RIGHT
import { isMobile } from 'pixi.js';
isMobile.any();NEVER use `settings.RESOLUTION` — configure via `AbstractRenderer.defaultOptions` or init options.
// WRONG
settings.RESOLUTION = 2;
// RIGHT
await app.init({ resolution: window.devicePixelRatio });NEVER use `updateTransform()` for per-frame logic — use `onRender` instead.
// RIGHT
mySprite.onRender = () => {
/* custom per-frame logic */
};NEVER use `ParticleContainer` with `Sprite` children — v8 requires `Particle` objects.
// WRONG
container.addChild(new Sprite(texture));
// RIGHT
container.addParticle(new Particle(texture));| Goal | Class to Use | Notes |
|---|---|---|
| App scaffolding | Application | Manages renderer + stage + ticker |
| Group/layer objects | Container | Only class that accepts children |
| Display an image/texture | Sprite | Fastest renderable; use spritesheets |
| Draw shapes programmatically | Graphics | v8: shape→fill order; shares GraphicsContext |
| Canvas-rendered text | Text | Flexible styling; expensive if updated every frame |
| High-perf static/dynamic text | BitmapText | GPU-batched; best for score counters, labels |
| HTML/CSS styled text | HTMLText | Rich formatting; slower than canvas text |
| 10k+ particles | ParticleContainer + Particle | Flat list, no children, requires boundsArea |
| Custom rendering batch | Mesh | Full shader control |
| 9-slice UI panel | NineSliceSprite | Renamed from NineSlicePlane in v8 |
| Tiling background | TilingSprite | Repeating texture |
| Load assets | Assets (static) | Global singleton, cached, async |
| GPU-optimized sub-tree | Container with isRenderGroup: true | Transforms applied on GPU |
