Single tool 'greet' with minimalist implementation. While the tool IS explicitly registered with a schema, the definition quality is poor: description is only 6 characters ('say hi'), lacks context about when/why to use it, parameters have descriptions in the schema but they are minimal. The tool does not follow verb_noun naming (should be 'greet_person' or similar), and there is no documentation of output schema or error handling. The prompt feature is present but disconnected from the tool. Overall, this is a demo/toy server not suitable for production use.

• Expand tool description from 'say hi' to 50 - 150 characters explaining the purpose: e.g., 'Greet a user by name from the current hostname and address. Returns a personalized greeting message.'
• Rename tool from 'greet' to 'greet_user' or 'send_greeting' to match verb_noun convention and clarify the action.
• Add explicit output schema to the tool definition documenting that it returns a greeting_text field (string).
• Add parameter description for 'name' in the tool definition to clarify that it accepts a user's name (string, required). Current schema only shows the JSON schema, not a human-readable description.
• Add error handling: document what happens if hostname lookup fails, if the server address is invalid, or if the name parameter is empty.
• Document the 'greet' prompt better: clarify that it is a code review prompt template and explain when/why an LLM should use it versus calling the tool directly.
• Consider adding a 'dry_run' parameter to show what the greeting would be without side effects, or document that this tool is read-only and idempotent.
