TDQS

A3.5/5.0

Scored across 11 tools

Disambiguation4/5

Most tools have distinct purposes (e.g., create_document vs. create_object vs. get_view), but some overlap exists: create_object and edit_object could be confusing since edit_object is described as a fallback for when create_object fails, and get_object vs. get_objects are similar but differentiated by singular vs. plural. Overall, descriptions help clarify boundaries, but minor ambiguity remains.

Naming Consistency5/5

All tool names follow a consistent snake_case pattern with clear verb_noun structure (e.g., create_document, delete_object, list_documents). There are no deviations in naming conventions, making the set predictable and easy to understand at a glance.

Tool Count5/5

With 11 tools, the count is well-scoped for a CAD modeling server like FreeCAD. It covers core operations (create, delete, edit, get, list) across documents, objects, and views, plus specialized tools (execute_code, insert_part_from_library), without feeling excessive or insufficient for the domain.

Completeness4/5

The toolset provides solid coverage for basic CAD operations, including document and object lifecycle (create, get, edit, delete) and view management. However, there are minor gaps: no explicit update or save operations for documents, and the execute_code tool might be a catch-all that could indicate missing specialized functions. Overall, agents can likely work around these gaps.
