Drive Local Webapp
Launch or connect to a local development web server and drive it with a reusable headless-Chromium command interface. Use when asked to render, smoke-test, interact with, verify, or screenshot a local frontend or HTML mockup.

Declared compatibility
Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

Drive a local web app
Use the bundled Playwright driver instead of writing a one-off browser script. It keeps one page alive while reading commands from standard input and reports each command as OK or FAIL.
One-time setup
Resolve this installed skill's directory, then run:
cd
npm ci
npx playwright install chromiumNode.js 20 or newer is recommended. Browser binaries are cached by Playwright. Verify the installation reproducibly:
npm run self-checkWorkflow
- Start the target application's normal development or demo server. Use
throwaway fixtures, never production or personal data. Check that the chosen port is free before binding it.
- Run
node scripts/driver.mjsfrom this skill directory and pipe one command
per line:
```sh DRIVERSCREENSHOTDIR=/tmp/webapp-shots node scripts/driver.mjs wait-for click fill :: set :: press wait eval screenshot [absolute-path] console --errors
Use `:text-is("Label")` for exact text. Playwright's `:has-text()` is
case-insensitive substring matching and can silently click the wrong control.
Keep screenshots outside the target repository. The driver defaults to the
system temporary directory, or use `DRIVER_SCREENSHOT_DIR`. It refuses to
overwrite an existing screenshot path.
## Common failures
- Selectors containing spaces require the literal ` :: ` separator for
`fill` and `set`.
- Hidden tab content may exist in the DOM; click the actual tab before waiting
on its contents.
- Charts initialized inside `display:none` containers may have zero width.
Activate the tab, wait, and verify the app resizes or lazily initializes the
chart.
- A client-side token gate may leave the screen loading without a console
error. Inspect the application's setup UI and use a demo token.
