| 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.

Workflow
- Identify the page path if it is not
/.
- Write the smallest snippet that performs the user-like action or reads the browser-only state.
- Run
vitexec '<snippet>', adding --path, --gpu, --screenshot, --record, or --config only when needed.
- 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.
