Test Chrome Extensions

View as Markdown

Test an unpacked Chrome extension by loading it into the browser at launch.

/shiplight verify my Chrome extension at ./my-extension works —
open https://example.com and check that the extension
injected its UI into the page.

Your agent launches Chromium in headed mode with the extension loaded. It can see and interact with any UI the extension injects into the page — content scripts, banners, sidebars, or modified DOM elements.

Combine with a persistent Chrome profile to test extensions with authenticated state:

/shiplight verify my extension at ./my-extension works on the dashboard —
use the Chrome profile at ./my-chrome-profile and open
https://app.example.com/dashboard

TIP

Screenshots and video recordings capture the page content only — the browser toolbar (with extension icons) is not included. Verify your extension works by checking its effects: DOM changes, console logs, network requests, or storage state.
