H-Index

Each tool serves a distinct purpose: get_listing retrieves a specific registry item, list_categories provides taxonomy for filtering, and search_registry performs semantic queries. There is no overlap in their functions, making tool selection straightforward.

All tool names follow a consistent verb_noun pattern in snake_case: get_listing, list_categories, search_registry. The naming is predictable and clearly communicates the action and target resource.

With only three tools, the server is tightly scoped for a read-only registry search service. Every tool is necessary and no redundant functionality is present.

The tools cover the core operations for a registry index: browsing categories, searching, and retrieving details by ID. There are no obvious dead ends or missing critical features for the stated purpose.
