Two tools with basic schemas and descriptions, but significant gaps in parameter documentation and output schema clarity. get_all_users has no parameters (empty properties object), which is acceptable but lacks pagination guidance. add_one_user has two required parameters with type and description, meeting minimum standards. Both descriptions are concise (34-50 chars) but lack context on when to use them, prerequisites, or what the response structure contains. No output schemas documented. Error handling exists but is generic ('An unknown error occurred'). Tool names follow verb_noun convention correctly. Overall: functional but below production baseline.

• Document output schemas for both tools. For get_all_users, specify: returns array of objects with fields {id: string, name: string, email: string, createdAt: ISO8601}. For add_one_user, specify: returns {id: string, name: string, email: string, createdAt: ISO8601}.
• Add pagination to get_all_users: introduce limit (1-100, default 20) and offset (default 0) parameters. Return {users: [...], total: number, hasMore: boolean} to enable multi-page iteration.
• Enhance parameter descriptions with format and constraint details. Email: 'Valid RFC 5322 email address (e.g., [email protected])'. Name: 'User's full name (1-255 characters, alphanumeric and spaces only)'.
• Expand tool descriptions to 100-150 chars. Include what the tool returns and when to use it. E.g., 'Retrieve all registered users in the system. Returns paginated list with user IDs, names, and emails. Use to discover existing users before creating new accounts.'
• Implement error categorization in CallToolRequestSchema handler. Return structured errors: {isError: true, content: [{type: 'text', text: 'Email already exists. Try a different email or call get_all_users to check availability.'}]} for add_one_user conflicts.
