Three tools with clear verb-noun naming (list_feeds, read_feed, fetch_feed) and reasonable descriptions (120-180 chars). All tools have input schemas with type definitions and required fields properly marked. However, parameter descriptions lack actionable constraints (no enums for category, no min/max for limit), and output schemas are completely undocumented. Error handling is absent from visible code. The server follows basic tool structure but lacks production-grade polish around validation, error guidance, and response documentation.

• Add formal JSON Schema output definitions for each tool. Example for list_feeds: {type: 'object', properties: {feeds: {type: 'array', items: {type: 'object', properties: {id, title, category, source, description}}}}}
• Convert 'category' parameter to enum: ['business', 'economics', 'marketing', 'real-estate'] in inputSchema.properties.category
• Add minimum and maximum constraints to 'limit' parameter: {type: 'number', minimum: 1, maximum: 50, default: 20}
• Implement structured error responses with recovery hints. E.g., when feed not found: {error: 'Unknown feed "xyz". Valid ids: ' + Object.keys(FEEDS).join(', ')}
• Document pagination strategy for list_feeds if result set can exceed 50 items. Add offset/page parameters and return total_count to enable agent-driven pagination.
