The server defines 3 tools with explicit schemas and descriptions. Tool names follow verb_noun convention (create_tasklist, update_task, get_status) which is good. Descriptions are present and between 100-200 chars, meeting baseline expectations. Schemas are well-structured with proper types and constraints (e.g., enum for status, min/max for evaluation score). However, there are notable gaps: parameters lack comprehensive descriptions (e.g., 'updates' object in update_task has no description explaining what it does), output schemas are not documented anywhere, and error handling is minimal. The tools operate on session-scoped state without explicit guidance on idempotence, idempotent operation pattern is not explicitly declared.

• Document output schemas for all three tools. Example: get_status should return {tasks: [{id: string, title: string, status: string, acceptanceCriteria: string, evaluation?: number}], taskListId: string, total: number} so LLMs know what fields to extract.
• Add descriptions to all parameters. For 'updates' in update_task, write: 'Object containing the fields to update. Omit fields you do not want to change. At least one field is required.'
• Add error recovery hints to tool descriptions. E.g., update_task: 'If taskListId is invalid, you may have lost the session. Call create_tasklist() to start a new task list or ask the user for the list ID.'
• Declare idempotence explicitly. Add to create_tasklist: 'Idempotent: calling multiple times with the same initialTasks will return the same list ID without duplicate tasks.' Add to update_task: 'Idempotent: retrying with the same updates is safe and will not double-apply changes.'
• Clarify parameter semantics in descriptions. For taskListId and taskId, state that they are session-local identifiers returned by prior tool calls, enabling LLMs to understand the dependency chain.
• Add parameter type hints in descriptions where JSON Schema alone may be ambiguous. E.g., initialTasks: 'Optional array of 0+ task objects. Each task must have title (1-256 chars) and acceptanceCriteria (1-1024 chars). If omitted, creates an empty task list.'
• Add bounds and constraints to numeric parameters. E.g., evaluation: 'Numeric score from 0 to 100 (inclusive). Typically used to track progress or completion percentage.'
