Server has 8 tools with basic naming and descriptions, but significant gaps in schema completeness, parameter documentation, and error handling. Tool names follow verb_noun convention (search_events, get_event_details, score_event_fit, rank_event_candidates, generate_campaign_brief, generate_copy_variants, generate_image_prompt, generate_draft_poster), which is positive. However, descriptions are generic (avg ~60 chars, well below the 194-char baseline for A+ tools). Input schemas visible but lack depth: parameters have type and description, but no enums, constraints, or validation guidance. No output schemas documented. No error handling patterns visible. Complex nested objects (intent, brief, image_concept) passed as parameters without field-level documentation. This is typical of early-stage community servers.

• Document output schemas for all tools. Example: search_events should return {events: [{event_id, name, date, location, audience_fit_score}], total_count, next_cursor}. This enables chaining to score_event_fit and rank_event_candidates.
• Expand tool descriptions to 100-200 chars. Add WHEN to use and dependencies. Example: 'Search for upcoming events in a city. Call this first to discover candidates, then pass results to rank_event_candidates() to score against campaign intent.'
• Break down complex nested objects into documented sub-schemas. For 'intent' parameter, document required fields: {city: string, brand_category: enum[...], audience: string, campaign_goal: string, constraints: object}.
• Add input validation constraints. For 'timeframe', use enum: ['next 7 days', 'next 30 days', 'this month', 'this quarter'] instead of free-form string.
• Implement error handling patterns. When event_id not found, return: {error: 'Event not found', suggestion: 'Try search_events() with city and timeframe to discover available events.', retryable: false}.
