The server provides 5 READ_ONLY tools with clear naming (all start with action verbs: get_*). Descriptions are present and adequate (range 54-89 chars, averaging 72 chars). Input schemas are fully defined with proper JSON Schema types and descriptions for all parameters. However, output schemas are NOT documented anywhere, callers cannot see what fields to expect. Error handling exists but lacks recovery guidance. The tool descriptions are functional but brief and do not specify WHEN to use each tool vs. alternatives (e.g., when to call get_speakers vs get_speaker_details). Parameter descriptions are adequate but some could be more prescriptive about constraints (e.g., event_id 'defaults to nearest event' is vague about format/length). Overall: solid B-range server with good foundations but missing output documentation and LLM-optimized guidance.

• Document output schemas for every tool. For get_events, specify: returns List[{ id: string, name: string, location: string, start_date: string (ISO 8601), end_date: string (ISO 8601), venue: object, status: 'past'|'ongoing'|'future' }]. This enables LLMs to chain tools and extract the right fields.
• Add WHEN-to-use guidance to tool descriptions. Example: 'Get information about Nerdearla speakers. Use this to list speakers with optional filtering by event, name, or bio. For detailed speaker bio/social links, use get_speaker_details() instead.' This disambiguates overlapping tools.
• Expand parameter descriptions with discovery hints. For event_id, add: 'Event ID (e.g., 703n9ws8 for Chile 2026). If unknown, call get_events() first to list all events and their IDs.' This prevents agent dead-ends.
• Add result limit documentation. For get_speakers/get_sessions, specify: 'Returns up to 100 results. Use the q parameter to filter by name/title for narrower results.' Then implement truncation if needed.
• Enhance error messages with recovery actions. Instead of returning 'Schedule will be available soon,' return 'Schedule is not yet available for event <event_id>. Check back later or call get_events() to see which events have published schedules.'
• Document expected value ranges for search parameters. For the 'q' parameter, specify: 'Search query (case-insensitive, max 256 characters). Matches against speaker names, bios, and taglines.' This guides LLM input formatting.
