Only 1 tool visible in source (generate_ai_reply). Tool has a basic description but NO input schema is visible in the provided code. The tool name follows verb_noun pattern (positive), but without seeing the actual schema definition, parameter descriptions, or output structure, quality cannot be assessed. The Dockerfile and package.json show a production HTTP gateway, but tool definitions are not included in the provided source excerpt. Critical: cannot verify schema presence, parameter types, or output documentation.

• Provide complete input schema for generate_ai_reply with typed parameters (e.g. message_id: string, user_id: string, tone?: enum[friendly|professional|casual]). Include min/max constraints and format hints.
• Expand tool description to 100-200 chars: explain what 'AI reply' means, when to call it vs other tools, and what the response contains. Example: 'Generate an AI-suggested reply to a message. Returns suggested_text and confidence_score. Use when the user wants AI assistance composing a response.'
• Document every parameter with type, description, and constraints. Example: 'message_id (string, required): The ID of the message to reply to. Format: UUID v4.'
• Document the output schema with field names, types, and descriptions. Example: {suggested_text: string, confidence_score: number 0-1, alternatives?: string[]}.
• For WRITE operations, add error handling guidance: 'If generation fails, return a recovery message with available fallback options. If the message is deleted, return a 404 with a suggestion to search for similar messages.'
