Single tool 'greet' has a critical naming issue and severely underdeveloped descriptions. Tool name 'greet' lacks an action verb prefix (should be 'send_greeting' or similar per pattern:tool). Tool description is only 40 characters, below the 10 - 1024 character baseline and provides no context for WHEN or WHY to use it. Input parameter 'name' has a description ('The name of the person to greet') that is adequate (47 chars), but the tool-level description is inadequate. No output schema is documented. No error handling guidance. The implementation is functional but falls far short of production-grade tool definition standards.
The name of the person to greet
Tool name 'greet' does not start with an action verb. Should be 'send_greeting', 'create_greeting', or similar to signal intent to LLMs.
Tool description is only 40 characters ('The name of the person to greet'). Baseline is 10 - 1024 chars; descriptions under 50 chars lack context for LLM selection. Should explain WHAT the tool does, WHEN to use it, and what it returns.
No output schema documented. LLMs cannot plan downstream calls or extract fields without knowing the response structure. Document the return type (e.g., 'Returns {content: [{type: string, text: string}]}')
No error handling guidance. If the tool fails (e.g., invalid input), there is no recovery hint for the LLM. Add error classification and actionable recovery steps.

Input schema is minimal. Parameter 'name' has minLength=1 but no maxLength, pattern, or format constraints. Add bounds and validation rules to prevent LLM hallucination of oversized or invalid names.
