Server has 7 tools with complete input schemas and descriptions. Naming follows verb_noun convention (list_tasks, add_task, edit_task, move_task, delete_task, add_comment, get_current_time). Descriptions are present but brief (avg 60 chars, below 194-char baseline). Parameters have types and descriptions. Critical gaps: no output schemas documented, no error handling guidance, no enum constraints for status/priority/estimate fields, no pagination support for list_tasks despite potentially large result sets, no idempotent hints on write operations, no confirmation pattern for destructive delete_task.

• Document output schemas for all 7 tools. Example: add_task should return {task_id: integer, title: string, status: string, created_at: string}. This enables chaining (e.g., add_task → edit_task with returned task_id).
• Convert status, priority, and estimate parameters to enums in JSON Schema. Replace free-form strings with constrained choices to prevent LLM hallucination.
• Add pagination to list_tasks: accept limit (1 - 100, default 20) and offset parameters; return {tasks: [...], total: integer, has_more: boolean}. Cap results at 50 items per call.
• Implement confirmation pattern for delete_task: add a dry_run boolean parameter or require a confirmation_token from a prior dry-run call to prevent accidental deletion.
• Add tool annotations: mark add_task, edit_task, move_task, add_comment with destructiveHint=false, idempotentHint=false (or true if idempotent); mark list_tasks, get_current_time with readOnlyHint=true.
