The server defines a single tool 'get_second_opinion' with a clear action verb and reasonable description. The input schema is present and includes proper JSON Schema structure with types and descriptions for all parameters. However, there are significant gaps in parameter descriptions (some are minimal), no output schema documentation, and missing structured error guidance. The tool follows basic composition principles but lacks the depth expected of production-grade implementations.

• Document the return schema explicitly. Example: 'Returns an object with { analysis: string (detailed AI-generated insights), markdown_path?: string (file path where response was saved) }'.
• Expand parameter descriptions to explain constraints and dependencies. Example for 'code': 'Relevant code snippet (max 5000 chars). Include only the section with the issue, not entire file contents.'
• Add error recovery guidance. Instead of 'Gemini API error: ...', return structured errors like: '{ error: "API_ERROR", message: "Gemini API call failed: rate limit exceeded. Retry in 30 seconds or try with fewer parameters.", retryable: true }'.
• Implement graceful degradation: if Perplexity or Stack Overflow fails, return the response with only Gemini analysis and a note about missing enrichment rather than failing entirely.
• Add timeout configuration for external API calls (recommend 15-30 seconds per service) and return a timeout error with retry guidance if exceeded.
• Document the filePath sandboxing approach. Add a description: 'Path to file with issue (relative or absolute). Must be within project directory. Automatic traversal protections prevent reading files outside project scope.'
• Add validation that GEMINI_API_KEY and PERPLEXITY_API_KEY are non-empty at startup and provide a clear error message if missing (this is already done but the error message could be more actionable).
