TDQS

A3.9/5.0

Scored 2026-08-07 10:45 across 3 tools

Disambiguation5/5

Each tool targets a distinct platform (Bluesky, Hacker News, Substack), so there is no overlap or ambiguity in purpose. The descriptions clearly specify the source and the type of data returned.

Naming Consistency5/5

All three tools follow the same verb_noun pattern: platform_search (e.g., bluesky_search, hn_search, substack_search). This makes the naming predictable and easy to navigate.

Tool Count4/5

Three tools is on the lower end but appropriate for a focused data collection server covering three specific sources. It is not too few to be useful, and each tool serves a clear purpose.

Completeness4/5

The server provides search functionality for each platform, which covers the core 'collect data' purpose. Minor gaps exist, such as no ability to fetch a specific post by ID or save/export results, but these are workable for most collection workflows.
