TrendRadar has 8 tools with generally clear naming (verb_noun pattern) and detailed descriptions. However, critical gaps exist: parameter descriptions are present but inconsistent in depth; output schemas are not explicitly documented in the visible code; error handling lacks recovery guidance; and tool composition could be tighter. The server demonstrates moderate quality with room for production hardening.

• Document output schemas for all tools. Specify return type (object/array), field names, types, and whether pagination is supported. Example: 'Returns {"success": bool, "news": [{"title": str, "source": str, "date": ISO8601, "url": str}], "total": int}'.
• Enhance error responses with recovery guidance. Instead of 'DataNotFoundError', return '{"error": "No data found for date range 2025-01-01 to 2025-01-07. Try resolve_date_range(\"last 7 days\") to get available data."}'.
• Expand get_rss_feeds_status description to 50+ chars explaining what status fields are returned (e.g., feed name, last update time, article count) and when to call it (e.g., before search_rss to verify feeds are active).
• Add min/max constraints to numeric parameters. E.g., 'limit: integer, 1 - 1000 (default 50)' and 'top_n: integer, 1 - 100 (default 10)' to prevent LLM from passing absurd values.
• Clarify tool selection logic in descriptions. Add to get_latest_news: 'Use for real-time trending news. For historical analysis, use get_news_by_date. For keyword search, use search_news_unified.'
