Server has 5 tools with basic structure but significant quality gaps. All tools have descriptions (good), but descriptions are generic and lack actionable context. Input schemas are present with type definitions, but parameter descriptions are minimal (1-3 words). No output schemas documented. Error handling returns JSON errors but provides no recovery guidance. Tools follow verb_noun naming convention. Missing: enum constraints, parameter ranges, dependency hints, and structured output documentation.

• Expand parameter descriptions to 50-100 characters each. Include format hints, valid ranges, and examples. E.g., 'data_id: Unique identifier for the data record (alphanumeric, 1-50 chars). Example: DATA_12345'
• Document output schemas for all tools. Specify returned fields, types, and whether they are required. E.g., 'Returns: {id: string, name: string, created_at: ISO8601, category: string}'
• Implement structured error responses with error codes, user-fixable hints, and recovery actions. E.g., '{"error": "NOT_FOUND", "message": "Data ID not found", "recovery": "Try search_data_by_query() with a keyword"}'
• Add enum constraints for 'category' parameter in create_new_data and update_existing_data. Replace free-form strings with validated options to prevent invalid input.
• For delete_data_by_id, add a 'confirm' boolean parameter (default false) or implement a separate 'confirm_delete' tool. Require explicit confirmation before irreversible deletion.
