- Authoring stage - typed Bifrost graph inspection and construction in Maya.
- Use to create graph shapes or boards, add Bifrost nodes, set input defaults,
- and connect ports before building procedural geometry or simulation tools.
+ Authoring stage - typed Bifrost procedural modeling and graph construction in Maya.
+ Use to generate reproducible multi-style houses, create graph shapes or boards,
+ add Bifrost nodes, set input defaults, and connect ports.
Not for ordinary Maya DG nodes (maya-node-graph), polygon edits
(maya-mesh-ops), or arbitrary Python/MEL (maya-scripting).

# maya-bifrost (Authoring stage)
Typed wrappers around Maya's supported Bifrost/VNN commands. The skill loads
`mayaVnnPlugin` and `bifrostGraph` on demand, then keeps graph changes on Maya's
main thread.
+ For a complete result in one call, use `generate_procedural_house`. Its `seed`
+ is reproducible across standalone mayapy and interactive Maya, while `style`
+ can select `cabin`, `cottage`, `modern`, `townhouse`, or choose randomly.
+
## Recommended flow
- 1. `list_bifrost_graphs` to inspect the scene.
- 2. `create_bifrost_graph` when a new graph container is needed.
- 3. `add_bifrost_node` with a fully-qualified type such as
+ 1. `generate_procedural_house` for a ready-to-view, seed-driven house graph.
+ 2. `list_bifrost_graphs` to inspect the scene.
+ 3. `create_bifrost_graph` when a new graph container is needed.
+ 4. `add_bifrost_node` with a fully-qualified type such as
`Modeling::Primitive::create_mesh_cube`.
- 4. `create_bifrost_port` when a dynamic port is required, such as inputs on
+ 5. `create_bifrost_port` when a dynamic port is required, such as inputs on
`Core::Array::build_array` or an Object port on the graph `output` node.
- 5. `set_bifrost_property` for unconnected input defaults.
- 6. `connect_bifrost_ports` using paths such as `.cube.cube_mesh` and
+ 6. `set_bifrost_property` for unconnected input defaults.
+ 7. `connect_bifrost_ports` using paths such as `.cube.cube_mesh` and
`.output.geometry`.
Use an explicit `Core::Array::build_array` node before ports that require
`array<Object>`; Bifrost does not implicitly promote an `Object` connection to
an object array.
