TDQS
Scored across 1 tool
With only one tool, there is no possibility of misselection; its purpose (open an STL in an interactive 3D viewer) is unambiguous and self-contained.
The single name view_part follows a clear verb_noun snake_case convention that reads predictably and would scale well if more tools were added.
One tool is thin for a CAD viewer surface; realistic use cases like re-viewing, closing a session, or exporting a screenshot have no counterpart, though the scope itself is narrow enough that a single entry point is defensible.
The tool covers a single format (STL) and a single action (view/measure), with no support for other CAD formats, section/measurement beyond the bounding box, or capture/export of the view. These are notable gaps an agent cannot work around, though the core stated purpose is met.
