FindUnderstandFix has well-structured tool definitions with clear naming (verb_noun pattern) and reasonable descriptions (avg ~120 chars). All 5 tools have input schemas with types and enums. However, several parameter descriptions are missing or trivial (e.g., 'difficulty' and 'type' in search_issues lack descriptions; 'limit' lacks description). Output schemas are not documented. Error handling returns basic error text but lacks recovery guidance or categorization. The server follows MCP SDK patterns correctly but lacks production-grade polish in parameter documentation and output structure.

• Add non-empty descriptions to all parameters. For 'difficulty' in search_issues: 'Filter by issue difficulty level. Defaults to any difficulty.' For 'type': 'Filter by issue type: bug reports or feature requests. Defaults to any type.' For 'limit': 'Maximum number of results to return (1-20, default 10).'
• Document output schemas for all tools. Example for search_issues: 'Returns array of issues with fields: url (string), title (string), difficulty (string), language (string), type (string), repo (string), stars (number).'
• Enhance error handling with recovery guidance. Instead of 'GitHub API error: 404', return 'Issue URL not found. Verify the URL is a valid GitHub issue (e.g., https://github.com/owner/repo/issues/123). Try search_issues() to find valid issues.'
• Add pagination support to search_issues: introduce 'offset' parameter (default 0) and return 'total_count' and 'has_more' fields so agents can iterate through large result sets.
• Add description to 'git_username' parameter: 'Your GitHub username for personalizing git commands in the guide (e.g., octocat). If omitted, generic commands are provided.'
