Two tools with minimal definitions. Both have descriptions (10-20 chars, below baseline 194 chars) and basic parameter schemas, but lack depth. 'hello' and 'add' are generic utility tools with trivial functionality. Descriptions are too short to guide LLM selection. Parameters have types but lack detailed constraints or usage guidance. No output schema documentation. No error handling guidance. No composition or chaining support. This is a demo/example server, not production-grade.

• Expand tool descriptions to 50-200 chars. Example: 'hello' → 'Greet a user by name to verify the MCP connection is working. Returns a confirmation message. Use this as a health check before calling other tools.'
• Document output schemas. Specify that 'hello' returns a string and 'add' returns a number. Include example outputs.
• Add parameter constraints. For 'add', specify that 'a' and 'b' are numeric (float/int), optionally with min/max ranges.
• Add error handling guidance. E.g., 'If the name parameter is empty, the tool defaults to "world". If numeric inputs are invalid, the tool returns an error message.'
• Consider renaming tools for clarity if this server grows. 'hello' → 'verify_connection', 'add' → 'calculate_sum' would better signal intent in a multi-tool environment.
