## What it does

The skill guides coding agents on connecting PixiJS v8 display containers to assistive software. It details setting `accessibleTitle` and `accessibleHint` so screen readers interpret canvas graphics correctly. Custom navigation order relies on `tabIndex`. Container elements must have `eventMode` set to `'static'` or `'dynamic'`, or PixiJS clamps the shadow element's `tabIndex` back to zero.

It covers runtime and setup options for `AccessibilitySystem`. By default, PixiJS keeps the overlay hidden until the user presses Tab. Mouse movement drops the accessibility layer immediately if `deactivateOnMouseMove` remains true. The AccessibilitySystem strictly requires the main browser thread and fails inside Web Workers, which defines how canvas rendering tasks can be partitioned.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add pixijs/pixijs-skills --skill pixijs-accessibility -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/pixijs-accessibility/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/pixijs-accessibility/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add pixijs/pixijs-skills --skill pixijs-accessibility -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/pixijs-accessibility/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add pixijs/pixijs-skills --skill pixijs-accessibility -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/pixijs-accessibility/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install pixijs/pixijs-skills pixijs-accessibility
```

2. **Manually: put the files in place**
- File: `.github/skills/pixijs-accessibility/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add pixijs/pixijs-skills --skill pixijs-accessibility -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/pixijs/pixijs-skills --path skills/pixijs-accessibility
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/pixijs-accessibility/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add pixijs/pixijs-skills --skill pixijs-accessibility -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

## When to use it
- configure keyboard navigation for PixiJS scene containers
- generate shadow DOM overlays for screen readers
- prevent accessibility deactivation when moving the mouse
- assign accessible titles and ARIA hints to game elements

## Example prompts
- Add accessibility properties and keyboard navigation to this PixiJS button
- How do I keep PixiJS AccessibilitySystem active when the mouse moves?
- Initialize PixiJS Application with accessibility enabled by default

Enable screen reader and keyboard navigation via PixiJS's AccessibilitySystem. The system creates an invisible shadow DOM overlay positioned over accessible containers so assistive technology can discover and activate them.

## Quick Start

```ts
const button = new Sprite(await Assets.load("button.png"));
button.accessible = true;
button.accessibleTitle = "Play game";
button.accessibleHint = "Starts a new game session";
button.eventMode = "static";
button.tabIndex = 0;
app.stage.addChild(button);

app.renderer.accessibility.setAccessibilityEnabled(true);

button.on("pointertap", () => startGame());
```

**Related skills:** `pixijs-events` (pointer/tap handlers), `pixijs-scene-dom-container` (HTML elements on canvas), `pixijs-application` (init options).

**Key points:**

- By default the system activates only after the user presses Tab. Set `enabledByDefault: true` in Application init for immediate activation.
- On mobile, the system creates a hidden touch hook; screen-reader focus activates accessibility for the whole session.
- The AccessibilitySystem requires the main thread; it is not available in a Web Worker.

## Core Patterns

### Container accessible properties

```ts
import { Container, Sprite } from "pixi.js";

const container = new Container();
container.accessible = true;
container.accessibleTitle = "Navigation menu";
container.accessibleHint = "Contains links to other pages";
container.eventMode = "static"; // required for custom tabIndex to apply
container.tabIndex = 0;
container.accessibleType = "div"; // defaults to 'button'

const sprite = new Sprite();
sprite.accessible = true;
sprite.accessibleTitle = "Close dialog";
sprite.accessibleText = "X"; // text content of the shadow div
sprite.eventMode = "static";
sprite.tabIndex = 1;
```

Available properties on any Container:

- `accessible` (boolean) - enables the accessible overlay div
- `accessibleTitle` (string) - sets the `title` attribute on the shadow div
- `accessibleHint` (string) - sets the `aria-label` attribute
- `accessibleText` (string) - sets inner text content of the shadow div
- `accessibleType` (string) - HTML tag for the shadow element, defaults to `'button'`
- `tabIndex` (number) - tab order for keyboard navigation (only applied when `interactive` is true / `eventMode` is `'static'` or `'dynamic'`)
- `accessibleChildren` (boolean, default `true`) - when `false`, prevents child containers from being accessible
