TDQS
A4.5/5.0
Scored across 2 tools
Disambiguation5/5
Each tool has a clearly distinct purpose: upload_data registers datasets, while visualize_data renders them. The descriptions explicitly define when to use each, leaving no ambiguity.
Naming Consistency5/5
Both tools follow the same verb_noun pattern (upload_data, visualize_data), which is consistent and predictable.
Tool Count4/5
At 2 tools, the server is slightly under the typical 3-15 range, but the tools form a complete two-step workflow for the narrow purpose of Vega-Lite visualization, so the count is reasonable.
Completeness4/5
The upload-then-visualize flow covers the core workflow, but there are no management operations (e.g., listing or deleting datasets), which are minor gaps that agents can work around by re-uploading with a new name.
