This server has 16 tools with significant quality gaps. Tool naming is inconsistent, multiple tools share identical names (list_todos, get_todo, add_todo, complete_todo, search_todos appear 2-3 times each across different files), violating the single-responsibility principle and creating ambiguity for LLMs. Descriptions are present but minimal (avg ~60 chars, well below the 194-char baseline for A+ tools). Parameter descriptions are sparse; many parameters lack type information in visible schemas. No output schemas are documented. Error handling is absent, no recovery guidance, no categorization of retryable vs. fatal errors. The code shows @Tool and @ToolParam annotations with descriptions, but schemas are inferred from method signatures rather than explicitly declared, making validation difficult. No evidence of pagination, rate limiting, or result capping despite tools returning lists.

• Rename tools to be globally unique and namespace-aware. E.g., 'personal_list_todos', 'external_list_todos', 'org_list_todos' or consolidate into a single canonical implementation with a 'source' parameter.
• Document output schemas explicitly. For each tool, declare the return type with field names, types, and descriptions. E.g., TodoView returns {id: long, title: string, memo: string, completed: boolean}.
• Expand descriptions to 100-200 chars. Include WHEN to use the tool and what distinguishes it from similar tools. E.g., 'Search todos by keyword in title and memo. Use this to find todos matching user intent; use list_todos to retrieve all todos.'
• Add pagination to list tools: accept limit (default 20, max 100) and offset/cursor parameters. Return total_count and next_cursor in responses to enable multi-page iteration.
• Implement error handling with recovery guidance. When a todo is not found, return {found: false, error: 'Todo not found. Try search_todos() to find by keyword or list_todos() to see all todos.'}.
