This server has critical definition quality gaps. Tool descriptions are minimal (6-40 chars, well below the 194-char baseline). Parameters lack descriptions in most tools. Input schemas are present but sparse. Two tools are duplicated (fetch_documentation, get_weather) with inconsistent naming/descriptions. No error handling guidance, no output schemas documented, no tool annotations. The math tools (add, multiply) have adequate schemas but trivial descriptions. The RAG/fetch tools lack parameter validation hints and output structure documentation.

• Remove duplicate tools. Keep one fetch_documentation and one get_weather with consistent English descriptions and parameter names.
• Expand all descriptions to 50-200 chars. Example: 'add' → 'Add two integers and return their sum. Use for arithmetic calculations in multi-step math problems.'
• Add parameter descriptions for all tools. Example: fetch_url url param → 'HTTP(S) URL to fetch. Must be accessible and return text/html or text/plain content.'
• Document output schemas. Example: fetch_url returns 'string (plain text with HTML tags stripped)'. fetch_documentation returns 'string (markdown-formatted documentation)'.
• Add error handling guidance to fetch_* tools. Example: 'If URL is unreachable, returns error message with timeout hint. If domain not allowed, returns permission error with allowed domains list.'
