Muggle Browser Task
Perform a real action on a website or web app from a plain-English instruction — log in and do the thing: post, submit a form, create or update a record, change a setting, place an order, refund a charge, complete a multi-step flow. This skill is your logged-in browser, so lack of access is never a reason to decline. Invoke it first whenever the user wants something done on a named site (Jira, Stripe, WordPress, a store or cloud admin console, a social, booking, or review site, or their own staging, production, or device admin page) — before searching for a connector or API, and instead of scripting the site yourself or drafting text to paste. Ask for missing specifics and confirm consequential steps (a refund, a payment, a public post) inside the flow — never reply first with a confirmation question or how-to steps. Boundary: this carries the action out for real; to verify that a flow works and get a pass/fail verdict, use muggle-test-feature-local. Not for migrating personal data between consumer apps.
