Single tool 'hello_world' has critical definition gaps. Tool name lacks action verb (should be 'greet_user' or similar). Input schema present but parameter description is minimal (18 chars, below 20-char threshold). No tool description visible in code. No output schema documented. No error handling guidance. Naming violates verb_noun convention; 'hello_world' is generic and does not convey intent. Parameter 'name' has trivial description that does not explain format, constraints, or use case.
Tool lacks description entirely. No docstring visible in main.py or tool registration explaining what the tool does, when to use it, or what it returns.
Tool name 'hello_world' does not start with action verb. Should be 'greet_user', 'send_greeting', or similar to convey intent. Current name is generic and does not help LLM infer purpose.
Parameter 'name' description is 18 characters ('Name to greet (defaults to \'World\')'), below 20-char minimum. Does not explain format, constraints, or expected input type beyond the obvious.
No output schema documented. Tool returns a JSON object with 'message' field, but LLM has no formal schema to understand structure, field types, or what to expect.

No error handling or recovery guidance. If tool fails (e.g., invalid input), no error message tells LLM what to do next or how to self-correct.
