name	houdini-node-graph
description	Authoring skill — inspect and edit Houdini node-graph relationships: list inputs/outputs/dependents and connect or disconnect inputs by explicit index. Use instead of arbitrary Python for wiring nodes. For parameters/expressions use houdini-parameters; for creating nodes use houdini-nodes.

houdini-node-graph

Typed node-graph relationship tools for agents. All tools are affinity: main because they call hou. Prefer these over houdini-scripting.execute_python for inspecting and wiring connections.

Tool groups

• graph-query (read-only): get_connections — inputs, outputs, dependents.
• graph-edit (mutating): connect_input, disconnect_input — explicit input/output indexes with structured failures.

Suggested flow

1. get_connections to understand current wiring
2. connect_input / disconnect_input to rewire by index

For parameter edits use houdini-parameters; for node creation use houdini-nodes.
