The server defines 13 tools with clear naming conventions (verb_noun pattern). Most tools have brief descriptions and declared input schemas with type information. However, there are critical gaps: (1) descriptions are generally terse (10 - 50 chars), below the 50 - 200 char baseline for LLM optimization; (2) parameter descriptions are minimal or absent for several tools, violating the requirement that every parameter have a description; (3) no output schemas are documented, leaving LLMs to guess what fields to expect from responses; (4) error handling guidance is absent, tools do not explain what to do on failure; (5) destructive operations (delete_page, edit_page, create_page) lack confirmation or dry-run patterns; (6) no pagination or result-limiting is evident for list tools. The server lands in the 'Fair' range, definitions exist and are structurally sound, but lack the depth and LLM-oriented guidance needed for production-grade reliability.

• Document output schemas for all 13 tools. For each, specify: return type (object, array, string), top-level fields, field types, and examples. E.g., search returns [{title: string, snippet: string, pageid: number}, ...]; get_page returns {title: string, text: string, lastmodified: string}.
• Expand tool descriptions to 80 - 150 chars, adding context: WHAT the tool does, WHEN to use it vs similar tools, and any prerequisites. E.g., 'Search Wizzypedia pages by keyword. Use when you need a partial name or topic match. Returns up to 50 results; use list_pages to enumerate all pages in a namespace.' vs current 'Search for pages on Wizzypedia using the MediaWiki search API'.
• Add detailed parameter descriptions to list_pages: 'namespace: The MediaWiki namespace to list from (valid: Main, User, Template, Special, File; default: Main)'. Similar for get_page_backlinks, get_page_revision_history.
• Implement confirmation or dry-run for destructive operations. E.g., add a 'dry_run: boolean' parameter to delete_page and edit_page, or introduce a 'confirm_deletion' tool that returns a confirmation token, and require that token in delete_page. Document the flow in descriptions.
• Add pagination support to list_pages and get_page_backlinks: accept 'offset: number' and 'limit: number' (default 20, max 100), and return {results: [...], offset: number, total: number, has_more: boolean}.
• Add error handling guidance to all tool descriptions. E.g., 'If the page does not exist, the tool returns an error with code not_found. Try search() with a partial name to find similar pages.' Include common failure modes and recovery steps.
