name	houdini-geometry
description	Authoring skill — create common SOP primitives and inspect SOP geometry: point/prim/vertex counts, bounds, attributes, groups, and cook errors. Use these typed tools to query and seed geometry before falling back to custom scripts. For mesh edit operations (transform/merge/blast) use houdini-mesh-ops.

houdini-geometry

Typed SOP creation and inspection tools for agents. All tools are affinity: main because they call hou. Prefer these over houdini-scripting.execute_python for seeding and querying geometry.

Tool groups

• geometry-create: create_primitive (box/sphere/grid/tube/curve/null/output).
• geometry-query (read-only except cook): get_geometry_info, list_attributes, list_groups, get_cook_status.

Tracer-bullet flow

1. create_primitive(parent_path="/obj/geo1", primitive="box")
2. get_geometry_info → counts and bounds
3. edit with houdini-mesh-ops (transform/merge/blast/group/normal/convert)
4. get_cook_status → verify no cook errors

get_cook_status is async with a timeout hint because heavy SOP graphs can cook slowly.
