This server exhibits several definition quality issues that substantially limit production readiness. While tool naming follows the verb_noun pattern (analyze_*, compare_*) and descriptions are present, there are critical gaps in schema definition, parameter documentation, and error handling. All five tools accept only string parameters with minimal constraint documentation. Output schemas are entirely undocumented, the server returns unstructured string concatenations rather than typed, structured objects. Parameter descriptions are minimal (single phrases like 'Path to the zip file...') and lack format constraints, expected ranges, or error cases. Error handling is absent; there are no recovery guides or actionable error messages visible in the code. The tools perform complex multi-step analysis (error extraction, categorization, report generation, comparison) but expose no indication of success/failure status, validation results, or partial completion handling. This is typical of a research or prototype tool not yet hardened for agent integration.

• Split 'analyze_cls_errors_and_save_report' into 'analyze_cls_errors' (read-only) + 'save_analysis_report' (write). Same for trajectory. This lets agents analyze without forcing file saves.
• Define input schemas with proper JSON Schema: validate zipPath is a non-empty string, optionally add a regex pattern for file paths, add minLength/maxLength constraints.
• Document return types explicitly. E.g., 'Returns a JSON object with fields: {total_errors: int, by_type: {string: int}, report_path: string|null, skipped_inner_zip: int, skipped_cls_log: int}'.
• Replace unstructured string concatenation output with proper typed objects. Return {'total_errors': 123, 'by_type': {'ValueError': 45, ...}, 'report_path': '...'} instead of 'Total errors: 123\nError type count: {...}'.
• Add parameter descriptions with format constraints: 'zipPath (required): Absolute or relative path to a .zip file containing MSBench execution logs. Must be readable and valid ZIP format. Max 500 MB.'
• Implement error handling: catch FileNotFoundError, ZipFile errors, and malformed log entries; return {'success': false, 'error': 'Invalid zip file: <reason>', 'recovery': 'Verify the file exists and is a valid zip archive.'} for LLM recovery guidance.
• Add a 'limit' parameter to analysis tools (default 100, range 1 - 10000) to cap results and support pagination. Return 'total_count' and 'result_count' so agents know if results were truncated.
• Document side effects clearly. For tools that save reports, explicitly state the output file path pattern and whether existing files are overwritten.
