Three tools with complete schemas and descriptions, but significant gaps in parameter documentation and output schema clarity. All tools have action verbs (list_, read_, fetch_) and descriptions (194-250 chars, within baseline). However, parameter descriptions are minimal or missing context. No output schemas documented. Error handling present but not recovery-focused. Naming is clear and follows verb_noun convention.

• Document output schemas for all three tools. Example for list_feeds: 'Returns array of {id: string, title: string, category: string, source: string, description: string}'. For read_feed/fetch_feed: 'Returns {items: [{title, link, published, summary}], total: number}'.
• Add min/max constraints to 'limit' parameter in JSON schema: {type: 'number', minimum: 1, maximum: 50, default: 20}. Update description to reference the schema constraint.
• Expand parameter descriptions to 50-100 chars. E.g., 'feed' → 'Curated feed id from list_feeds (e.g., openai, deepmind). Use list_feeds to discover valid ids.'
• Enhance error messages with recovery guidance. E.g., 'Unknown feed "xyz". Call list_feeds() to see valid ids.' and 'Invalid URL format. Pass http:// or https:// URLs.'
• Document result limits and pagination in tool descriptions. E.g., 'Returns up to 50 items (default 20). Use limit parameter to control page size. No cursor-based pagination; use query filter to narrow results.'
