The server implements 7 tools with explicit registration and mostly complete schemas. However, there are significant quality gaps: (1) Parameter descriptions are missing or extremely sparse in the input schemas (e.g., 'focus' and 'exclude' in analyze_repo have minimal guidance on expected format or values). (2) Output schemas are completely undocumented, the tools return JSON text but the structure of that JSON is never specified. (3) Tool naming is somewhat generic ('analyze_repo', 'find_patterns') but acceptable. (4) Error handling is basic (try/catch with message wrapping) but lacks recovery guidance and categorization. (5) No tool annotations (readOnlyHint, destructiveHint, idempotentHint) despite all tools being READ_ONLY. (6) Descriptions are brief but mostly adequate (avg ~140 chars), though they lack specificity on dependency chains (e.g., 'expand_section requires analysisId from previous analyze_repo call' is mentioned but not tied to expected output format). The server demonstrates a functional baseline but falls short of production-grade quality due to missing parameter constraints, absent output documentation, and lack of error recovery guidance.

• Document the output schema for each tool. For analyze_repo, specify: { analysisId: string, sections: Array<{ sectionId: string, title: string, summary: string, canExpand: boolean }>, metadata: { language: string, fileCount: number, ... } }. Make this explicit in tool registration or a companion reference.
• Add enum constraints to 'depth' parameter: depth: z.enum(['surface', 'standard', 'deep']) instead of z.string(). Repeat for other constrained parameters (patternTypes should list valid options like ['singleton', 'factory', 'observer', 'adapter', ...]).
• Expand parameter descriptions: 'focus': 'Array of specific areas to analyze (e.g., ["authentication", "data-layer", "api-routes"]). If empty, analyzes entire codebase.' 'exclude': 'Glob patterns to exclude (e.g., ["node_modules/**", "dist/**", "*.test.ts"]). Standard glob syntax.'
• Implement tool annotations in the schema registration. Add readOnlyHint: true to all tools (all are read-only). Example: server.tool('analyze_repo', ..., { readOnlyHint: true }).
• Improve error responses with recovery guidance. Instead of returning { content: [...], isError: true }, return structured errors: { content: [{ type: 'text', text: 'Error analyzing repository: path not found. Try verify_path() first or provide a GitHub URL.' }], isError: true }.
• Add numeric bounds to tokenBudget: 'Maximum token budget (100 - 1000000, default: 100000). Higher values enable deeper analysis but increase latency and cost.'
• Document dependency chains explicitly: 'expand_section requires an analysisId returned by a prior analyze_repo call. Pass the same analysisId to access cached analysis without re-cloning.'
