Each tool has a clearly distinct purpose: get_answer retrieves direct answers to specific questions, list_topics enumerates all available topics, and search_articles performs keyword-based searches. There is no overlap in functionality, making tool selection unambiguous for an agent.

All tool names follow a consistent verb_noun pattern (get_answer, list_topics, search_articles) with clear, descriptive verbs. The naming is uniform and predictable across the entire set.

Three tools is reasonable for a knowledge base server, covering core operations like querying, listing, and searching. It might feel slightly thin if advanced filtering or topic management were expected, but it's well-scoped for basic access.

The tools provide good coverage for accessing a knowledge base: retrieving answers, listing content, and searching. A minor gap is the lack of tools for updating or managing the knowledge base, but this is acceptable if the server is read-only.
