Single tool 'greet' with minimal definition. Tool name lacks action verb clarity (should be 'greet_user'). Description is present but extremely brief (18 chars, below 20-char threshold). Input schema exists with basic structure but parameter 'name' lacks description. No output schema documented. No error handling guidance. Tool appears trivial (greeting only) and does not reflect production-grade agent patterns. Naming, description, and schema all fall below baseline standards for A+ tools.

• Rename 'greet' to 'greet_user' to follow verb_noun convention and signal action intent to LLM.
• Expand tool description to 50 - 150 chars: 'Greet a user by name and return a personalized greeting message. Use this to acknowledge users at the start of a conversation.'
• Add description to 'name' parameter: 'The user's display name, email, or username to greet (e.g., john, [email protected]).'
• Document output schema: {greeting_text: string, user_id?: string, timestamp: ISO8601}. Specify what fields are always present vs optional.
• Add error handling: 'If user not found, return error with available user names. If name is empty, return error: "name is required."'
