Server has 9 tools with complete input schemas and descriptions present. However, descriptions are minimal (10-50 chars), parameter descriptions lack depth, and output schemas are not formally documented. Tool naming follows verb_noun convention (search-, get-) which is good. No tool annotations (readOnlyHint, destructiveHint) despite all tools being read-only. Error handling exists but lacks recovery guidance. Composition is reasonable, tools are single-purpose and chainable via ISBN/categoryId. Major gaps: descriptions too terse for LLM optimization, no output schema documentation, missing parameter format constraints.

• Expand tool descriptions to 50-200 characters. Example: 'search-books' → 'Search the Aladin book catalog by title, author, or publisher. Supports filtering by category, publication date, and stock status. Returns up to 50 results per page with ISBN, price, and link.'
• Document output schemas explicitly. Define the structure returned by each tool (e.g., {title: string, author: string, isbn13: string, priceSales: number, link: string, ...}) so LLMs know what fields to expect.
• Add readOnlyHint: true to all tool definitions since all 9 tools are read-only queries. This signals to agents that these calls are safe to retry and have no side effects.
• Enhance error messages with recovery guidance. Instead of 'No search results for "xyz"', return 'No results for "xyz". Try: (1) removing special characters, (2) searching by author instead, (3) browsing bestsellers or new releases.'
• Add format constraints to ISBN parameters. Clarify: 'ISBN (10 or 13 digits, no hyphens required; e.g., 9788901234567 or 8901234567)' to prevent LLM confusion about valid formats.
