Single tool 'greet' has a clear verb-noun name and basic description. Input schema is properly typed with jsonschema tag. No error handling guidance, no parameter constraints, and no indication of idempotency or side effects. Lacks composition context (when to use this tool vs alternatives). Meets bare minimum for a toy example but falls short of production quality.

• Expand description to 50-200 chars. Example: 'Greet a person by name and return a friendly greeting. Use this to generate personalized welcome messages. Returns a text greeting.'
• Document the output schema explicitly. Specify that the tool returns a TextContent with a 'text' field containing the greeting string.
• Add constraints to the 'name' parameter. Example: 'name (string, 1-100 chars): The person's name or display name to greet. Accepts first name, full name, or username.'
• Add error handling guidance. Example: 'If name is empty or exceeds 100 chars, the tool returns an error. Retry with a valid name between 1-100 characters.'
• Consider whether this tool is idempotent and document it. If calling greet('Alice') twice always returns the same greeting, state 'Idempotent: safe to retry.'
