Scored across 1 tool
With only one tool, there is no possibility of overlap or misselection. The tool's purpose is clear and distinct.
The single tool name discover_cosign follows a clear verb_noun convention. There are no other names to conflict with, so consistency is trivially perfect.
A single tool for a discovery server spanning people, companies, products, and jobs feels thin. It could be appropriate for a unified search endpoint, but typically more granular or complementary tools would be expected.
The server only provides search, with no obvious way to retrieve details for a specific entity, list available data sources, or paginate. These gaps may limit follow-up actions for an agent, though the core discovery operation is present.
