TDQS

A4.4/5.0

Scored 2026-08-01 02:15 across 4 tools

Disambiguation5/5

Each tool has a clearly distinct purpose: browsing the MasterFormat taxonomy, searching for manufacturers, retrieving a specific manufacturer's details, and searching for products. There is no meaningful overlap that would cause an agent to confuse them.

Naming Consistency5/5

All tool names follow a consistent verb_noun pattern with clear, descriptive verbs (browse, get, search, search) and underscore separators. The naming is predictable and idiomatic.

Tool Count5/5

With four tools, the server is well-scoped for its purpose of discovering building product information. Each tool covers a distinct aspect of the domain without excess or redundancy, fitting comfortably within the 3-15 range.

Completeness4/5

The tool set covers the primary workflow: browse the taxonomy, search for manufacturers, get manufacturer details, and search products. A minor gap is the lack of a direct 'get_product' or a way to list products by manufacturer ID, but agents can work around this via keyword search.
