Granola exhibits solid foundational quality with clear, action-oriented tool names and generally well-structured schemas. All 8 tools have explicit descriptions (100-250 chars range), proper input parameter schemas with types, and consistent READ_ONLY classification. However, there are notable gaps: (1) Parameter descriptions are sometimes generic or incomplete, e.g., 'Filter by attendee name or email' lacks format guidance. (2) Output schemas are documented in code via Pydantic models but descriptions do not enumerate what fields the agent will receive. (3) No error handling guidance, tools return plain strings on 404 but lack recovery suggestions. (4) No pagination metadata or per-result success/failure tracking for list operations. The server demonstrates mid-range maturity: better than median community servers (baseline ~50) but below production-grade (80+) due to incomplete parameter guidance and missing response documentation.

• Add output schema documentation to every tool description. Example for search_meetings: 'Returns SearchResponse with fields: query (str), total_results (int), results (array of {id, title, date, score, snippets})'.
• Formalize 'sort' in list_meetings as enum with explicit options: sort: enum('date_asc', 'date_desc', 'title') instead of free-form string.
• Formalize 'format' in get_transcript as enum: format: enum('text', 'timestamped') with description 'Output format. text = plaintext, timestamped = includes speaker and timestamp for each segment.'
• Add recovery guidance to error responses. When get_meeting returns 'Meeting not found', append suggestion: 'Meeting not found: {id}. Try search_meetings(query=...) or list_meetings() to find the meeting ID.'
• Document pagination clearly in list_meetings and search_by_person. Add to description: 'Supports pagination via limit (max 50, default 20) and offset. Response includes total_results count.' Then ensure response includes total_results field.
• Clarify attendee parameter format. Change description from 'Filter by attendee name or email' to 'Attendee name, email, or partial name match (case-insensitive). E.g. "alice" or "[email protected]".'
• Add default and validation guidance for date parameters. Example: 'date_from: Start date (YYYY-MM-DD, default: 90 days ago). Must be <= date_to.'
• Clarify extract_action_items 'meeting_id' parameter: 'meeting_id (optional, string). If provided, extracts actions from that meeting. If omitted, searches across all meetings in date range.'
