The server defines 1 tool (add) with complete naming, clear description, and a valid input schema with typed parameters. The tool follows verb-noun convention (add) and has explicit integer parameters with descriptions. However, the tool set is trivial (basic arithmetic) and does not demonstrate patterns like pagination, error handling guidance, composition, or idempotent operation verification. The single tool is well-formed but insufficient to assess production-grade patterns. Output schema is implicit (returns int) and not formally documented. Resource support (greeting://{name}) is present but not evaluated as a tool. No evidence of error handling patterns, confirmation workflows, or multi-step composition. The implementation is correct but minimal.

• Add a third tool that chains with 'add' (e.g., multiply, divide) to demonstrate tool composition and ID forwarding patterns.
• Document the return schema formally: 'Returns an integer (sum of a + b)'. Explicit return types enable LLM planning.
• Add error handling: validate that inputs are not absurdly large (e.g., >10^15) and return actionable errors like 'Invalid input: a must be between -10^15 and 10^15'.
• If the 'add' tool is meant as a template, replace it with a domain-specific tool (e.g., create_task, send_message) to demonstrate realistic patterns.
• Add rate-limit or timeout documentation if the server will be deployed at scale.
