Server has 4 tools with complete schemas and descriptions. Naming follows verb_noun convention (generate_*, explore_*, mix_*). Descriptions are present and adequate (100-200 chars), meeting baseline. However, parameter descriptions lack actionable constraints (no ranges, formats, or validation guidance). Error handling returns isError flags but lacks recovery guidance. Output schemas are implicit (JSON text responses) rather than explicitly documented. No tool annotations (readOnlyHint, destructiveHint). Resource endpoint present but minimal. Overall: solid foundation with gaps in parameter rigor and error guidance.

• Add min/max bounds to numeric parameters: 'top' should be 1-100. Document in description: 'Return top N trends by popularity (1-100, default 10)'.
• Enhance error messages with recovery guidance. E.g., 'Error generating prompt: <message>. Try simplifying your description or use explore_trends to find inspiration.'
• Return structured objects instead of JSON text. Change generate_prompt to return {prompt: string, tokens_used: number} instead of wrapping in content[0].text.
• Add readOnlyHint to all tool definitions: server.tool(..., {...}, {readOnlyHint: true}, async (...) => {...}).
• Document parameter formats in descriptions. E.g., 'query: Search keyword (1-50 chars, alphanumeric + spaces). Example: "dark theme minimalist"'.
