Use when authoring or editing OAS-Core JSON — rooms, walls, openings (doors/windows), curtain walls, roofs, floor slabs, furniture, railings, or annotations in a 2D floor plan.
Use when adding or editing OAS extension blocks — machinery, materials, site, MEP, or Autodesk metadata — that augment a Core or Layout document.
Use when writing or debugging OAS geometry — points, polygons, line segments, arcs, circles, spirals, fillets, units, or coordinate conventions. Load before any geometry-heavy edit.
Use when capturing OAS design intent — room requirements, area targets, adjacency rules, circulation rules, or global constraints — before any geometry has been resolved.
Use when mapping OAS plans to a visual output — SVG, Canvas, or WebGL — including scale, axis orientation, and z-order layering.

Use this skill whenever the task is "give me the resolved plan" — concrete polygons, walls with coordinates, openings placed on walls, multiple levels, stairs/elevators connecting levels. If you're only authoring single-level core entities without level/connection scaffolding, oas-core may be enough. If the task is intent-only (no geometry), use oas-program.
levels — abstract reference planes (id, name, elevation_mm, optional is_building_story)rooms, walls, openings, curtain_walls, roofs, floor_slabs, furniture, railings — Core entities, each with optional level referenceconnections — inter-room circulation graph: { from, to, type } where type is direct | through | single_accessmetadata — optional provenance (generated_by, timestamp, notes)from/to points only — not polylines. For a bent wall, emit multiple wall entities.position_along_wall_mm ≥ 0 and position_along_wall_mm + width_mm ≤ Euclidean distance between wall.from and wall.to.Level is abstract; FloorSlab is physical. Level is the reference plane (elevation_mm); FloorSlab is the construction. A single Level can have multiple slabs (split-level designs).Connection is a room-to-room graph, not a vertical traversal. Types are direct (shared doorway), through (passes through other rooms), single_access (room only reachable via one neighbor). Vertical movement between levels is modeled via openings + level refs on the room/opening, not a special connection type.top_profile_points. Each entry is { "t": 0..1, "z_mm": int } where t is the parametric position along the wall, not an absolute coordinate.slope_angles, defines_slope, and eave_overhang_mm must each have exactly as many entries as the polygon has points. Edges where defines_slope is false are gables.in_wall or in_curtain_wall, never both. Curtain wall panels (IfcPlate) are not openings — only doors/windows are.See docs/layout.md for the complete reference — the largest module in OAS, covering levels, all entity placements, and connection semantics.
