Scored across 10 tools
Disambiguation5/5
Each tool is clearly distinct, targeting a specific chart type or visualization method (e.g., Cartesian, heatmap, hierarchical, Sankey). The descriptions precisely differentiate purposes, such as trend analysis for Cartesian charts versus flow relationships for Sankey diagrams, leaving no ambiguity for selection.
Naming Consistency5/5
All tool names follow a consistent verb_noun pattern with 'generate_' as the prefix (e.g., generate_cartesian_chart, generate_heatmap_chart). This uniform naming convention makes the tool set predictable and easy to navigate for agents.
Tool Count5/5
With 10 tools, the server is well-scoped for chart generation, covering a comprehensive range of visualization types from basic charts like scatter and bar to specialized ones like Sankey and word clouds. Each tool earns its place without redundancy or excessive bloat.
Completeness5/5
The tool set provides complete coverage for data visualization, including common chart types (Cartesian, scatter, polar), specialized visualizations (heatmap, hierarchical, Sankey), and utility charts (progress, word cloud/Venn). There are no obvious gaps; agents can handle diverse visualization needs without dead ends.
