Implementation Reference
- src/neem/mcp/tools/hocuspocus.py:644-705 (handler)The handler function that executes the move_artifact tool. It authenticates, validates inputs, reads current artifact state from Y.js workspace, updates the parent folder and order using WorkspaceWriter, and returns the updated workspace snapshot.

The function signature provides the input schema.
