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, ranges, or format specs), output schemas are undocumented, and error handling is minimal. The server lacks pagination guidance despite accepting 'limit' parameters. No tool annotations (readOnlyHint, idempotentHint) despite all being read-only operations.

• Add enum constraints to schema: category should be enum: ['books', 'entertainment']; limit should have minimum: 1, maximum: 50 in the schema itself, not just description.
• Document output schemas for all three tools. E.g., list_feeds returns {categories: string[], count: number, feeds: [{id, title, category, source, description}]}.
• Add readOnlyHint: true to all tool definitions since they perform no mutations and are safe to retry.
• Enhance error messages with recovery guidance. E.g., 'Unknown feed "xyz". Valid feeds: variety, hollywood-reporter, pitchfork. Call list_feeds() to see all options.'
• Add pagination metadata to responses: return total_count and next_cursor (or offset) so agents can iterate large result sets without re-fetching.
