Single tool with basic registration but significant quality gaps. Description is present (47 chars, within 10-1024 range) but generic and lacks WHEN/WHY context. Input schema uses Zod but parameter description is null, violating the requirement that every parameter must have a non-empty description. Output schema is implicit (text content) but not formally documented. No error handling guidance, no validation constraints on text length/content, no idempotency declaration. Tool is read-only (low risk) but lacks the structured quality expected of production tools.

• Add non-empty description to 'text' parameter: 'The text to convert to ASCII art (1-200 characters, alphanumeric and spaces only)'
• Expand tool description to 100-150 chars: 'Create large ASCII art text using figlet fonts. Useful for generating decorative headers, banners, or text art. Input text should be 1-200 characters.'
• Add input validation: document max text length (e.g., 200 chars) and allowed character set in parameter description
• Document output schema explicitly: 'Returns a text/plain response containing the ASCII art as a single string'
• Add error handling: wrap figlet.textSync() in try-catch and return actionable errors like 'Text too long (max 200 chars)' or 'Invalid characters in input'
