Who handles a Singapore errand or government process, the official link, login needs and next step

Use for an errand, government process or practical how-to in Singapore, for residents, employers and visitors. It says which agency or type of business handles the task, the official channel and URL, whether Singpass, Corppass or a UEN is needed, whether it is fully online or needs a visit, fees and processing times only where the official page states them, whether an agent can act or must hand off to the user (login, app or phone), the next step, and any related API or MCP tool. Covers, among others: passports, NRIC and change of address; visas, the SG Arrival Card, tourist GST refunds at the airport, paying for MRT and buses as a visitor, SIM cards at Changi; personal and company income tax, GST registration, company and business registration and annual filing; work passes and domestic helper permits (new and renewal); HDB matters such as season parking, bulky item disposal, home-based businesses and neighbour or smoking complaints; municipal issues, police reports, scams, vehicles, road tax and parking; utilities, CPF, healthcare appointments, ActiveSG court bookings, school registration, pets; sending parcels; and buying office supplies or event print. Returns the best 1 to 3 matches from a list checked against official pages, each with source_url and last_checked. Says plainly when a task is not covered, and labels any agency suggestion for it as a guess. Singapore only; not for other countries, and not for recommendations such as restaurants or sights. Read-only.
