Single tool 'send_message' has a basic schema and description but lacks depth. Description is only 43 characters, below the 50-200 char baseline for LLM-optimized descriptions. Parameter 'message' has a type and description, meeting minimum requirements, but no constraints (length, format, examples of valid input). No output schema documented, LLMs cannot predict what fields to expect. No error handling guidance. Tool is write-capable (WRITE risk) but no confirmation or dry-run pattern. Overall structure is present but falls short of production quality.

• Expand description to 80-150 chars: 'Sends a message to the server console for debugging or logging. Use this to trace agent execution flow. Returns confirmation of receipt.'
• Add output schema to tool definition: document that response is {content: [{type: 'text', text: string}]}
• Add constraints to message parameter: maxLength (e.g. 1000), minLength (e.g. 1), and description: 'Plain text message (1-1000 chars). No special formatting required.'
• Add error handling: validate message is non-empty string; return actionable error if validation fails, e.g. 'Message cannot be empty. Provide a non-empty string.'
• Document idempotency: clarify whether repeated calls with the same message produce duplicate console logs or are deduplicated.
