vitexec

name	vitexec
description	Use this skill when an AI agent needs to inspect, verify, or debug a live Vite app by running temporary snippets inside the browser page and reading browser logs. Use for client state after interactions, imported app modules, DOM state, human-like input, canvas/WebGL/Three.js state, screenshots, videos, WebXR/Three.js XR with IWER, and runtime-only behavior without editing app files.

vitexec

Use vitexec when the truth lives in the running browser: client state, imported app modules, DOM, canvas/WebGL, screenshots, recordings, or browser-only errors.

Do not use it for questions static files, unit tests, or TypeScript can answer directly.

References

• If vitexec or Playwright is missing, read references/install.md.
• For mouse, keyboard, pointer lock, gamepad, or other input, read references/inputs.md.
• For WebXR, read references/webxr.md.

Workflow

1. Identify the page path if it is not /.
2. Write the smallest snippet that performs the user-like action or reads the browser-only state.
3. Run vitexec '<snippet>', adding --path, --gpu, --screenshot, --record, or --config only when needed.
4. Treat stdout as browser logs. It starts with logs:.

vitexec 'console.log("ready")'

For structured state, log JSON:

vitexec --path /cart '
  import { useCartStore } from "/src/store/cart.ts";
  document.querySelector("[data-testid=add-to-cart]")?.click();
  await new Promise((resolve) => requestAnimationFrame(resolve));
  console.log("cart", JSON.stringify(useCartStore.getState()));
'

Guidance

• Prefer importing exported app state over scraping DOM when state is available.
• Use direct state reads for observation and assertions, not to bypass user interaction.
• Prefer browser-root imports such as /src/store.ts, not local filesystem paths.
• Use --gpu for WebGL, canvas, Three.js, and WebXR behavior.
• For WebXR apps, read references/webxr.md; the passing proof should enter an emulated XR session, not only a desktop fallback.
• For CI-style XR proof, wrap or post-process vitexec output when needed so missing milestones, browser/page errors, and missing screenshots/recordings fail even if the CLI exits 0.
• Use screenshots or recordings only when visual evidence matters.
• Do not leave temporary code in the app when vitexec can inspect it from outside.
