This multi-server repository exhibits severe definition quality gaps across all 8 tools. Most tools lack descriptions entirely (add, summarize) or have minimal ones. Input schemas are present but parameter descriptions are sparse or missing. Tool naming is inconsistent: 'add' appears twice with identical signatures, violating the single-responsibility principle. The 'edit_document' tool lacks output schema documentation. No error handling guidance, no pagination support for list_roots/read_dir, and no security considerations for file operations. The repository appears to be educational material rather than production-grade tooling.

• Remove the duplicate 'add' tool. If both notifications and sampling servers need arithmetic, consolidate into one server or rename one (e.g., 'add_numbers' vs 'add_with_notification').
• Add descriptions to 'add' and 'summarize' tools. E.g., 'add': 'Add two integers and return their sum. Use for arithmetic operations.' (50-100 chars).
• Document output schemas for all tools. E.g., read_doc_contents returns {"content": string, "doc_id": string}; list_roots returns {"roots": [{"path": string, "readable": boolean}]}.
• Add parameter descriptions with format/constraint hints. E.g., 'path' in read_dir: 'Absolute or relative path to directory. Must be within one of the client's configured root directories.'
• Add error handling guidance to file operation tools. E.g., edit_document: 'If old_str not found, returns error with suggestion to call read_doc_contents first to verify exact text.'
