worker-visualizer SKILL.md skillA
worker-visualizer from muselinn/musepi is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add muselinn/musepi/worker-visualizer@git:20261007.0100f6bPins git:20261007.0100f6b in mdr.lock. Pin the fingerprint instead.

A real-time data/particle/simulation visualizer whose heavy compute runs in a Web Worker (off the main thread), optionally sharing memory with the UI via SharedArrayBuffer, and renders to a canvas at 60fps. Produced as a single self-contained `index.html`. Use when the brief asks for a "web worker", "simulation", "particle system", "physics", "off-main-thread", "fractal", "real-time compute", or "audio/data visualizer". OpenDesign serves this in powered-preview mode so Workers and…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Worker Visualizer Skill Produce a single self-contained `index.html` that moves heavy per-frame compute into a Web Worker and renders the result to a canvas, keeping the main thread at a smooth 60fps. ## Why this is a powered artifact OpenDesign detects `new Worker(` / `SharedArrayBuffer` / `OffscreenCanvas` and renders this file in **powered preview** — a cross-origin-isolated iframe with `allow-same-origin`. That means external and blob Web Workers construct successfully, `SharedArrayBuffer` is defined (`crossOriginIsolated === true`), and `importScripts` works. In the old opaque sandbox all three failed; here they just work. ## Resource map ``` worker-visualizer/ ├── SKILL.md ← you're reading this └── example.html ← a working 12k-particle SharedArrayBuffer sim (READ FIRST) ``` ## Workflow ### Step 0 — Read the reference …

How to install
mdr add muselinn/musepi/worker-visualizer@sha256:5a36b7ca3d07b245The line at the top of this page pins the label git:20261007.0100f6b, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
