TaskTracker MCP exhibits significant definition quality gaps across multiple dimensions. Tool naming is adequate (verb_noun pattern followed), but parameter descriptions are inconsistent and often minimal. Parameter schemas are present but lack depth, many parameters have descriptions under 20 characters. Output schemas are not explicitly documented in the code (tools return inferred types via ctx.request_context.lifespan_context["api"] calls). Error handling is minimal: tools return {'error': 'not found'} without recovery guidance. Five of 13 tools have descriptions under 30 characters (get_all_tasks_tool: 28 chars, get_all_plan_steps_tool: 33 chars). Parameter descriptions like 'The ID of the task to retrieve' (tool 2, 4) meet minimum viability but lack format/constraint details. No parameter enums or range validation visible. Schema documentation missing from docstrings, LLMs cannot infer what fields are returned. Composition is reasonable (13 tools, each with one responsibility), but the suite lacks pagination for list operations (get_all_tasks_tool, get_all_plan_steps_tool, get_notes_tool return unbounded lists). Resource-backed tools repeat data loading without pagination hints. The lifespan pattern and API abstraction are sound, but tool definitions themselves do not match production baselines (194 chars avg description, 72 chars avg param description).

• Add pagination to list tools: get_all_tasks_tool and get_all_plan_steps_tool should accept 'limit' (default 20, max 100) and 'offset' parameters, and return {items: [...], total: N, has_more: bool}. Cap results at 50 items per response.
• Document output schemas for all tools. Example for get_task_tool: 'Returns: {id: string, title: string, description: string, priority: 1-3, status: string, created_at: ISO8601, updated_at: ISO8601}' in the docstring.
• Expand descriptions for get_all_tasks_tool, get_all_plan_steps_tool, get_notes_tool to 50+ characters explaining WHEN to use them. Example: 'Retrieve all tasks in the system. Use this to list available tasks before creating or updating. Returns paginated results.' (currently 28-35 chars).
• Convert inline enums to JSON Schema enum constraints. For 'status' parameter in add_task/update_task, add 'enum': ['not_started', 'in_progress', 'completed'] to the schema. For 'priority', add 'enum': [1, 2, 3] with description 'Priority level: 1=highest, 3=lowest'.
• Add constraint descriptions: 'title' (required, 1-200 chars), 'description' (optional, max 5000 chars), 'task_id' (required, UUID format), 'priority' (required, enum: 1-3).
• Improve error responses with recovery guidance. Example: If get_task_tool(task_id='unknown') returns not found, return: {'error': 'Task unknown not found', 'suggestion': 'Call get_all_tasks_tool() to list available tasks, or call add_task() to create a new one.'}
• Add a confirm_delete_task tool or require a 'confirm=true' parameter on delete operations. Alternatively, document that delete_task and delete_plan_step are irreversible and agents should call get_task_tool or get_plan_step_tool first to confirm ID.
