Critical gaps across naming, descriptions, and schemas. Most tools lack input parameter schemas entirely (inferred from code, not explicitly registered). Descriptions are present but generic (10-50 chars typical). No output schemas documented. Tool names are inconsistent: some use verb_noun (get_overview, write_dashboard), others are noun-only (inbox_send, finish_meeting_session). Security-sensitive tools (inbox_send, setup_slack_app) expose tokens as parameters rather than using server-side injection. Error handling is absent, no recovery guidance or categorization. Composition is poor: inbox_send and inbox_send_token are tightly coupled; meeting ingestion spans two tools without clear sequencing. This server reads like a collection of internal scripts exposed as tools, not a production-grade MCP implementation.

• Add explicit JSON Schema input definitions for all 16 tools. Include type, description, and constraints for every parameter. Example: get_calendar_events should declare days as {type: 'integer', minimum: 1, maximum: 365, description: 'Number of days to look ahead (1-365)'}.
• Expand tool descriptions to 100-200 characters. Include WHEN to use the tool and what it returns. Example: 'Fetch upcoming Google Calendar events for the specified number of days. Returns event title, start/end times, and attendees. Use this to check availability before scheduling.'
• Move tokens and credentials out of parameters. Inject config_token and Slack credentials via environment variables at server startup. Update inbox_send and setup_slack_app to read from server state, not parameters.
• Document output schemas for all tools. Specify response structure, field types, and pagination. Example: get_calendar_events returns {events: [{title, start, end, attendees}], total_count, next_cursor}.
• Implement error handling with recovery hints. Catch file-not-found, permission-denied, and timeout errors. Return structured errors: {error: 'file_not_found', message: 'Dashboard.md not found at /path/to/Dashboard.md', suggestion: 'Create the file or check the path with browse_files()'}.
