This server demonstrates good definition quality with strong naming conventions, comprehensive tool descriptions, and well-structured schemas. All 18 tools follow verb_noun naming pattern (list_, get_, create_, update_, add_, search_, run_, flag_, archive_, inbox_, trash_). Descriptions are clear and action-oriented, ranging from 40-180 chars. All tools have explicit input schemas with proper type definitions and parameter descriptions. Tool annotations (readOnlyHint, destructiveHint, idempotentHint) are present on most tools, supporting proper agent reasoning about safety. However, output schemas are not documented in the source code, the tool definitions show only input schemas. Parameter descriptions are good but could be more prescriptive about constraints and dependencies. Three tools (drafts_create_draft, drafts_update_draft, drafts_add_tags) lack proper error handling guidance in descriptions.

• Document output schemas for all 18 tools. Add a structured example or TypeScript interface describing the response object, fields, types, and any nested structures. Reference these in the tool description so LLMs know what to expect.
• Add error handling guidance to tool descriptions. For example, drafts_get_draft should note: 'Returns error if UUID is invalid or draft is deleted. Use drafts_search() to find valid draft UUIDs.' For drafts_run_action, specify: 'Returns error if action does not exist; use drafts_list_actions() to verify.'
• Implement a dry-run or confirmation pattern for drafts_trash. Either add an optional 'confirm' parameter, or split into drafts_trash (which stages for deletion) and drafts_confirm_trash (which finalizes). Agents make mistakes, a confirmation step prevents catastrophic data loss.
• Add format constraints to date parameters. Change createdAfter description to: 'Filter drafts created after this date (ISO 8601 format: YYYY-MM-DD or YYYY-MM-DDTHH:MM:SSZ).'
• Clarify optional vs required parameters in descriptions. For drafts_get_drafts, state: 'All parameters are optional. Omit to retrieve all drafts. Combine filters with AND logic (tag AND folder AND query, etc.).'
• Add response pagination guidance. If tools like drafts_list_workspaces or drafts_list_tags can return many items, add limit and offset parameters and document the response includes a total_count or next_cursor field.
• Document idempotency explicitly. Tools like drafts_add_tags should state: 'Idempotent, adding an existing tag to a draft is safe and produces no duplicate.' This helps agents retry without fear.
