# maya-expressions (Authoring stage)

Lifecycle for Maya expression nodes (`expression` DG nodes). Four small
scripts � kept as a dedicated skill rather than folded into
`maya-scripting` because they have a stable schema and benefit from
typed parameters.

## Scripts

- `create_expression` � Create a Maya expression node
- `list_expressions` � List Maya expression nodes in the scene
- `delete_expression` � Delete a Maya expression node by name
- `get_expression_string` � Read the MEL expression body of a node
