OAS Layout

When to use

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.

Key entities (top-level arrays in a Layout document)

• 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 reference
• connections — inter-room circulation graph: { from, to, type } where type is direct | through | single_access
• metadata — optional provenance (generated_by, timestamp, notes)
