The server defines 4 tools with schemas and descriptions present, but quality is below production baseline. Tool names follow verb_noun convention (positive), but descriptions are minimal and parameter documentation is inconsistent. All tools are READ_ONLY which is safe, but descriptions lack LLM optimization guidance. Schemas are present in the code but lack proper typing and constraint documentation in the descriptions themselves. No tool has a documented output schema. Error handling exists but does not guide recovery with actionable next steps. The server is STDIO-only, which further constrains its production viability.

• Expand tool descriptions to 100-200 characters and include WHEN to use each tool. Example: 'get_newsnow: Fetch the latest news from a single source (e.g., 微博, GitHub, Bilibili). Use this when you need trending topics from one platform. Call list_sources() first if you don't know valid source names.'
• Document output schemas for each tool. At minimum, describe the structure: 'Returns: {"data": [{"title": string, "url": string, "published_at": ISO8601 date}], "error": string|null, "total": number}'
• Add constraints to 'source' and 'sources' parameters: 'source (string, required): News platform name or alias. Accepts Chinese names (e.g., 微博) or English codes (e.g., weibo). Call list_sources() to see all 14 available options. Aliases like "b站" → "bilibili-hot-search" are auto-normalized.'
• Improve error messages to guide recovery. When source is unrecognized, return: '{"error": "unknown_source", "message": "Source not found: xyz. Did you mean: weibo, douyin? Or call list_sources() to see all 14 available sources."}' instead of returning the full available sources list unprompted.
• Add pagination support to get_all_news(). Currently no limit parameter, if there are 100+ articles across 14 sources, returning all at once exhausts context. Add optional 'limit' (default 20, max 100) and 'offset' parameters.
• Document per-source timeout expectations. The code sets a 300-second timeout but this is not mentioned in descriptions. Users/LLMs need to know if a source is slow or unreliable.
• Clarify relationship between list_sources() and the other tools. 'list_sources() returns all available news sources, call this first if you are unsure which source to query with get_newsnow().'

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