Both tools lack input schemas entirely (empty {} objects), have minimal descriptions (under 20 chars), and provide no parameter documentation. Tool names 'hello1' and 'hello2' are generic and non-descriptive, violating verb_noun naming conventions. No output schema documentation. No error handling guidance. This is a minimal proof-of-concept, not production-ready.

• Rename tools to follow verb_noun convention: 'greet_user' or 'send_greeting' instead of 'hello1'/'hello2'. Include the action in the name so LLMs understand intent without reading the description.
• Expand descriptions to 50-150 characters. Example: 'Send a friendly greeting message to the user. Returns a personalized greeting string.' This explains WHAT, WHEN, and WHAT it returns.
• Add explicit input schemas with typed parameters. Even if a tool takes no parameters, declare 'input: {type: object, properties: {}, required: []}' to signal that the tool is intentionally parameter-free.
• Document the output schema. Declare that both tools return a string response: 'output: {type: object, properties: {message: {type: string}}, required: [message]}'.
• Add error handling. Define what happens if the greeting service is unavailable, and return actionable error messages like 'Greeting service unavailable. Retry in 30 seconds.' instead of silent failures.
