TailwindDesigner has well-structured tool definitions with complete schemas and descriptions for all 5 tools. All parameters are typed with enums and constraints (min/max). Descriptions are present and actionable (avg ~80 chars). However, output schemas are not documented, tools return text responses without structured field definitions, forcing LLMs to parse unstructured JSON. Error handling is basic (isError flag + text message) but lacks recovery guidance. Tool composition is sound (single responsibility), but the generate-tailwind-component tool returns a placeholder message rather than actual output, limiting practical utility. No tool annotations (readOnlyHint/destructiveHint) despite clear risk classifications.

• Document output schemas for all tools. Define return type as structured object with typed fields (e.g., search-designs returns {designs: [{id, title, url, source, tags}], total_count, has_more}). Include in tool description or separate schema block.
• Add recovery guidance to error messages. E.g., 'Design with ID xyz not found. Call get-trending-designs() or search-designs() to discover available designs.' Pattern: recovery-guide.
• Implement tool annotations in MCP server.tool() calls. Add readOnlyHint: true for search/get tools, destructiveHint: true for remove-design. Enables clients to enforce safety policies.
• Implement generate-tailwind-component fully. Analyze image metadata (colors, layout, tags) and generate actual Tailwind HTML+CSS code. Return structured {html, css, explanation} instead of placeholder text.
• Add pagination support. Return total_count and next_cursor in search-designs and get-trending-designs responses. Accept offset/cursor parameter to fetch additional pages. Prevents context window overflow.
