Four tools with basic descriptions and schemas, but significant gaps in parameter documentation and output structure. Tool names follow verb_noun convention (health_check, list_available_feeds, get_latest_news, search_news), which is good. However, parameter descriptions are embedded in tool docstrings rather than in schema annotations, making them invisible to strict schema parsers. Output schemas are not documented. Error handling is minimal. The server lacks tool annotations (readOnlyHint, destructiveHint) despite all tools being read-only. No pagination guidance despite tools returning lists.

• Add enum constraint to 'category' parameter in get_latest_news schema: {"enum": ["tech", "general", "business", "science", "travel", "politics"]} instead of free-form string.
• Document output schemas for all tools. E.g., health_check returns {"status": string, "version": string, "feeds_available": integer, "categories_available": integer}. get_latest_news returns {"articles": [{"title": string, "link": string, "summary": string, "published": string, "source": string}], "error": string (optional)}.
• Add tool annotations to schema: set readOnlyHint=true and idempotentHint=true for all four tools to signal safety to agents.
• Enhance error messages with recovery guidance. E.g., if category is invalid, return {"error": "Invalid category: got 'xyz'. Valid options: tech, general, business, science, travel, politics. Call list_available_feeds() to see all categories."}
• Document pagination behavior in get_latest_news and search_news descriptions: 'Returns up to [limit] articles (max 20). If more results exist, call again with different category or search term. No cursor-based pagination; results are sorted by published date descending.'

Inferred effective spec: <=2025-11-25.

• Relies on Logging (deprecated) - log to stderr or use OpenTelemetry
