Server presents 19 well-organized tools with consistent naming, clear descriptions, and documented input schemas. Tool names follow verb_noun convention (search_tool, get_page_tool, list_pages_tool, create_page_tool, etc.), which is strong. Descriptions are present and contextual, averaging ~80-120 characters, within the productive range (baseline 194 chars for production tools, but these are appropriately scoped). All tools have input schemas with typed parameters and descriptions. However, there are gaps: (1) Output schemas are not documented in the function signatures or docstrings, the code shows parameter docs but no explicit return schema structure; (2) Error handling is implicit in the tool implementations but not surfaced in descriptions, no guidance for LLMs on what to do if a page is not found, authentication fails, or rate limits are hit; (3) Some parameter descriptions could be more precise (e.g., 'timestamp' format not specified as ISO 8601 in text, though ISO 8601 is implied by the word 'timestamp'); (4) No input validation constraints visible in descriptions (e.g., 'limit max: 50' is mentioned in descriptions for search_tool but not consistently applied to all paginated tools; list_pages_tool and others claim 'max: 500' but validation is not shown in code excerpt); (5) Destructive tools (delete_page_tool) lack confirmation-request or dry-run patterns; (6) Tool parameters do not include rate-limit guidance or backoff semantics. Overall, the server is well above median, tools are usable and LLMs can reason about them, but production-grade polish is missing.

• Document output schemas for all 19 tools. Add a 'Returns' section to each tool docstring that lists the fields in the returned dict, their types, and what they represent. Example: 'Returns: {"pages": [{"title": str, "ns": int, "pageid": int}], "query-continue": {...}} or similar structure derived from actual implementation.
• Add error handling guidance to destructive and write tools. For delete_page_tool, edit_page_tool, create_page_tool, and move_page_tool, add text like: 'Errors: Raises 401 if not authenticated; 403 if user lacks permission; 404 if page not found (try search_tool or list_pages_tool first); 409 if edit conflict.'
• Implement a confirmation pattern for delete_page_tool. Add a 'dry_run' bool parameter (default false) or a separate 'preview_delete' tool that shows what would be deleted without committing. This prevents accidental data loss.
• Standardize parameter constraint documentation. Update all tool docstrings to explicitly state parameter min/max/enum/format in the 'Args' section, not just in the description text. Example: 'limit: int, default 50, range 1 - 500'.
• Clarify timestamp formats. For list_recent_changes_tool and list_user_contributions_tool, update the from_timestamp description to: 'from_timestamp: ISO 8601 timestamp (e.g., "2024-01-15T10:30:00Z"). Results start from this point in time.'
• Document pagination behavior. For each paginated tool, explain whether the continuation token (from_title, from_name, continue_from) is cursor-based or offset-based, and whether results are stable if the underlying data changes between calls. Example: 'Cursor-based pagination; results ordered by title; next batch starts from the last returned title.'
