Roomwise

Use this when the user already has furniture positions (or has edited a plan) and asks whether the arrangement works, for example whether a sofa blocks a door or sits too close to a coffee table. Checks them against the same clearance rules without moving anything. Each piece needs its position (its north-west corner measured from the room's north-west corner) and the direction it faces. Returns pass/fail for each rule with measured values such as the narrowest walkway. Do not use to find a new arrangement (use plan_room_layout) or to give structural or building-code advice.

check_room_layout

Use this when the user asks how much flooring, paint or baseboard a room needs for a remodel, renovation or refresh. Calculates quantities from the room's size and openings, with waste allowances, and the cost if unit prices are given. Returns floor area, paint gallons (exact and to buy), baseboard length and the assumptions used. Prices are in the user's own currency; flooring is priced per square foot, baseboard per foot and paint per gallon. Do not use for contractor quotes, labour costs, tile pattern layouts, or ordering materials.

estimate_room_materials

Use this when the user wants to plan, arrange or rearrange furniture in a room for a home redesign, remodel or decorating project, or to see whether a set of furniture will fit. Plans where furniture goes in one room, to scale, from the room's size, door and window positions, and a list of furniture with sizes, then checks the layout against clearance rules: walkway width, door swings, sofa-to-coffee-table distance, dining and storage clearance, and whether every seat can be reached. Returns each piece's position and facing, a pass/fail report with measured values, and links to view and edit the plan on the web. Do not use to redesign a room from a photo, choose styles, colours or decor, order furniture, or give structural or building-code advice.
