The server provides 4 well-structured RSS feed search tools with consistent naming patterns (verb_noun: list_feeds, search_feed, search_all_feeds, search_multiple_feeds). All tools have descriptions and explicit input schemas with types and parameter descriptions. However, there are notable gaps: output schemas are not formally documented (only examples in docstrings), error handling returns JSON strings instead of structured errors, and some parameter descriptions contain example values which can cause LLM hallucination. The server lacks input validation guidance in descriptions (e.g., 'max_results must be 1-20' is enforced in code but not stated in parameter descriptions). Parameter descriptions are present but generic, they lack constraints like 'feed_name must be one of: [list]' which would guide LLM selection. The max_results parameter defaults to 5 with a server-side cap of 20, but this constraint is not visible in the schema or description, forcing LLMs to guess valid ranges.

• Document output schemas formally. For search_feed, define: {feed: string, query: string, count: integer, results: array of {title: string, url: string, ...}}. Repeat for all search tools.
• Add parameter constraints to descriptions. Update max_results description to: 'Maximum number of results per feed. Must be 1-20 (default: 5). Values above 20 will be clamped.'
• Replace example feed names in descriptions with a constraint. Change 'e.g., freecodecamp_news' to 'See list_feeds tool for available names' or use an enum if feeds are static.
• Enhance error messages with recovery guidance. When feed_name is not found, return: {error: 'Feed "xyz" not found.', suggestion: 'Call list_feeds() to see available feeds', available_feeds: [...]}
• Add dependency hints in parameter descriptions. For search_feed, add: 'If you do not know the feed name, call list_feeds() first.'
• Consider adding pagination support (offset/limit or cursor) for feeds with many results, and document in tool descriptions.
