Four tools with adequate naming (verb_noun pattern), complete input schemas with proper types and enums, and reasonable descriptions. However, several critical gaps reduce the score: (1) Output schemas are not documented in the tool definitions, we cannot see what fields the search results contain beyond 'SearchResult[]'; (2) No pagination guidance despite search tools returning lists; (3) Error handling is basic, error messages are returned as strings but lack actionable recovery guidance or error classification; (4) Parameter descriptions are functional but generic, lacking format/constraint details expected in production tools; (5) No tool annotations (readOnlyHint, destructiveHint, idempotentHint) despite all tools being read-only. The server shows solid fundamentals (schemas present, naming clear) but lacks the production polish expected of A-grade tools.

• Document output schema for all search tools. Example: 'Returns an array of objects with fields: id (string), source (string), score (number, 0 - 1), content (string, first 200 chars), metadata (object). Total count and pagination cursor not provided, results are unsorted and capped at limit parameter.'
• Add pagination guidance to search tool descriptions. Example: 'Note: Results are returned unsorted and capped at the limit parameter. To retrieve more results, refactor your query to be more specific or use multiple sequential calls with different query terms.'
• Enhance parameter descriptions with format details. For 'query' param: 'UTF-8 string, 1 - 500 characters. Supports partial word matching. Special characters and syntax not supported, use simple whitespace-separated terms.'
• Add error recovery hints to tool descriptions. For catalog_search: 'If you receive an error about an invalid client, call collection_info() to see available clients (work, personal, research, projects).'
• Annotate tools with readOnlyHint=true to signal to agents that these tools are safe to call multiple times without side effects.
• Clarify collection_info behavior. Example: 'Lists all available client names and their associated collection names (e.g., work_catalog, work_chunks). Use this to verify client availability before calling search tools.'
• Consider batching: if agents frequently call catalog_search and chunks_search with the same query, add a combined tool (search_all_docs) that returns both catalog summaries and detailed chunks in one call, reducing round-trips.
