The server exposes a single tool 'add' with minimal definition quality. While the tool has a name and basic description, it lacks production-grade documentation. The description is extremely brief (21 characters), parameters have minimal context, and there is no error handling guidance or output schema documentation. The tool does not follow agentic patterns for clarity, parameter specificity, or error recovery.

• Rename 'add' to 'add_numbers' to follow verb_noun convention and improve clarity when multiple tools are available.
• Expand tool description to 100-150 characters: 'Adds two numbers together and returns the result as an integer or float. Supports positive, negative, and decimal values. Use this for arithmetic operations in calculations or data transformations.'
• Document parameter constraints: 'a' and 'b' should specify type (integer or float), valid range (e.g. -1e308 to 1e308), and handling of special values (NaN, Infinity).
• Add explicit output schema: specify that the response is a single numeric result (integer or float) and document the format (e.g. 'Returned as a JSON number or string representation').
• Include error handling in description: 'Returns an error if inputs are non-numeric or exceed numeric limits. Provide valid numbers and retry.'
• Consider whether this tool serves a real agent use case. A single arithmetic operation is unlikely to be useful in production agentic workflows. Add complementary tools (multiply, subtract, divide) or remove if demo-only.
