Activation
This is the description your AI agent reads to decide when to run this skill — the better it matches your request, the more reliably it fires.
Opens the running app in a browser and verifies recent UI changes actually work. Use whenever the user wants a quick smoke test or sanity check of recent work, or says "go", "open in browser", "check in browser", "test your work", "make sure it works", "smoke test", "verify", "did it actually work", "make sure the form/page works", "check the form submits", "works on mobile" — even when they don't explicitly ask for browser testing. Also activates implicitly when the user appends "...and make sure it works" to a UI request. Skips design critique; for that, use go-ui.Key capabilities
- →Open the running application in a browser
- →Verify recent UI changes
- →Check for functional verification, such as search results
- →Inspect console for JavaScript errors
- →Monitor network status for 4xx/5xx errors
- →Reload and re-verify after a fix
How it works
The skill opens the current application in a browser, using available browser tools like Chrome extension or Playwright, to verify UI changes and functional outcomes. It checks for console errors, network status, and expected page content.
Inputs & outputs
When to use go
- →Verify form submission works
- →Check recent UI visual updates
- →Confirm page loads without JS errors
- →Test mobile responsiveness
About this skill
/go — Browser check
Verify your work in the browser instead of trusting that code compiles. Use whatever browser tools the environment offers (Chrome extension, next-devtools MCP, chrome-devtools MCP, Playwright — whichever is reachable). If chrome-devtools MCP is available and you need console errors, network status, or computed styles to confirm the fix, prefer it over a blind reload. If login is needed, credentials usually live in .env.local or the project's secrets manager.
Two things are easy to miss:
- Functional verification — did the page actually return what was expected? Searching for "X" should show results containing X, not just render without errors.
- Console and network — JS errors and 4xx/5xx are silent killers.
If something is broken, fix → reload → verify again. Don't thrash on the same issue — ask for direction instead.
When not to use it
- →When the user asks for design critique
- →When the user does not explicitly ask for browser testing
Limitations
- →It skips design critique
- →It does not address issues that require asking for direction
How it compares
This skill automates the process of opening a browser and performing checks, unlike manually navigating to the application and inspecting elements.
