Single tool 'analyze_file_impact' has adequate naming and schema but lacks depth in descriptions and error handling. The tool is correctly named with a verb prefix (analyze_), has a documented input schema with proper types, but parameter descriptions are minimal. Output structure is generic (status/data/message pattern) without detailed field documentation. No error classification or recovery guidance. No tool annotations. STDIO transport caps protocol readiness at 50, which cascades into overall assessment.

• Expand parameter descriptions with format/constraint details: 'project_path: Absolute or relative path to project root (e.g., /home/user/myproject or ./). Must contain source files and git history.' 'target_file: Relative path from project_path to file to analyze (e.g., src/main.rs). Supported languages: Python, Rust, TypeScript, Go, Java, Kotlin, Swift, C#, C, C++'
• Document output schema explicitly: 'Returns dict with fields: status (string, one of "success" or "error"), data (list of objects with file (string) and symbols (list of strings) when status="success"; null when status="error"), message (string, empty on success, error details on failure)'
• Add error classification and recovery guidance: Replace generic exception handling with categorized errors like 'Invalid project_path: path does not exist. Verify path is correct and contains supported source files.' and 'Cache miss: graph creation failed. This may take 30+ seconds for large projects. Retry with same project_path to use cached result.'
• Add tool annotations via fastmcp: Use @app.tool(meta={...}) or similar to declare readOnlyHint=True since this tool does not modify state
• Document supported file types and language parsers in tool description: 'Analyzes code relationships in Python, Rust, TypeScript, Go, Java, Kotlin, Swift, C#, C, and C++ files using tree-sitter-based dependency graph'
• Consider adding optional limit parameter to cap result size: 'limit (integer, optional, default=100): Maximum number of related files to return. Set to -1 for unbounded results (may be slow on large projects)' with corresponding schema update
