• Document output schemas for all tools. For get_status, define: {status: string, uptime_seconds: number, tools_available: number}. For echo, define: {echoed_message: string, prefix: string, char_count: number}.
• Expand tool descriptions to 50 - 150 characters explaining WHEN to call them, not just WHAT they do. Example: 'Echo back a message with optional prefix. Use to test communication, validate input parsing, or construct dynamic prompts.'
• Add explicit constraints to numeric parameters. For add_numbers, specify: 'a and b: numbers between -1,000,000 and 1,000,000, inclusive. Decimal places up to 2.'
• Convert process_list 'operation' to an enum schema rather than free-form string. Update parameter description: 'Operation to perform: "count" returns item count, "join" concatenates with commas, "reverse" reverses order.'
• Add dry-run parameter to create_data: 'dry_run: boolean (optional, default false). If true, simulate creation and return what would be created without persisting.'
• Document failure modes and recovery for all tools. Example for echo: 'Returns error if message exceeds 10,000 characters. If you receive a length error, truncate the message and retry.'
• Remove or rename example_with_error, it signals a tool designed to fail, which is misleading. If demonstrating error handling, rename to test_error_handling and clarify it is for testing only.
• Add parameter descriptions for all array types (tags, items). Example: 'tags: array of strings, optional. Each tag 1 - 50 alphanumeric characters. Max 20 tags.'
