A3.8/5.0
Scored across 1 tool
Disambiguation5/5
With only one tool, there is no possibility of confusion or overlap. The tool's purpose is clear and singular.
Naming Consistency5/5
The single tool follows a clear verb_noun convention ('lookup_postal_code'), which is consistent even though there is no other tool to compare against.
Tool Count3/5
At one tool, the server feels thin for a domain like postal codes, which typically would benefit from additional operations like validation or listing supported countries. However, the singular lookup tool does cover the core function.
Completeness2/5
The server only supports lookup by postal code and country, but offers no way to list supported countries or validate a code. This is a significant gap for an agent needing to know the valid inputs, so the surface is incomplete.
