TDQS

A3.9/5.0

Scored 2026-10-02 12:50 across 8 tools

Disambiguation4/5

Most tools have distinct purposes (list_templates vs get_template, publish vs submit_feedback, whoami). However, check_template_data overlaps with create_from_template, whose description says region mismatches surface as a 400 'before anything is made — no separate check needed,' making the standalone checker partially redundant; publish_asset also overlaps with update_asset's publish:true flag. Descriptions largely resolve the boundaries, so it's a minor issue.

Naming Consistency4/5

Seven of eight tools follow a clean verb_noun snake_case pattern (check_template_data, create_from_template, get_template, list_templates, publish_asset, submit_feedback, update_asset). whoami is the lone outlier with no verb/noun structure, but the rest is highly predictable.

Tool Count5/5

Eight tools is well-scoped for a template-driven chart creation workflow, covering discovery, inspection, validation, creation, update, publish, auth, and feedback without bloat. Each tool earns its place.

Completeness3/5

Core lifecycle is covered, but update_asset references get_asset ('get_asset returns the current one to edit') yet no get_asset tool exists in the surface, forcing reliance on the last response envelope. There is also no delete_asset tool, leaving a notable gap in asset lifecycle management.
