Baibai exhibits significant definition quality gaps. Tool names lack consistent verb-noun structure (e.g., 'check_format' vs 'validate_directory' for similar operations). Descriptions are present but generic and under-optimized for LLM selection, most are 20-80 chars, below the 50-200 char baseline for A-grade tools. Critical issue: input schemas are visible but parameter descriptions are minimal or absent. For example, 'check_format' accepts 'filepath' with only 'type:string' and a 6-word description. No output schemas are documented anywhere. Error handling is absent, no guidance on what happens on validation failure, file not found, or permission errors. Tool composition shows poor separation of concerns: 'validate_directory' and 'analyze_directory' both iterate over files but serve different purposes without clear distinction. No pagination, no result limits documented. Security: tools accept file paths as strings with no visible sanitization against path traversal. Overall, this server reads as a thin CLI wrapper without LLM-specific optimization.

• Add output schemas to every tool. Document return type, field names, types, and descriptions. Example: 'Returns {success: bool, errors: [{line: int, message: string}], total_issues: int}'.
• Expand parameter descriptions to 50-150 chars. Include format hints, constraints, and examples. E.g., 'filepath (string): Absolute or relative path to a Markdown file. Must exist and be readable. Example: ./docs/guide.md'.
• Implement input validation with actionable error messages. Return 'File not found: /path/to/file.md. Check the path and try again.' instead of a 500 error.
• Add result limits and pagination. Document: 'Returns up to 50 matches. Use offset/limit parameters for pagination.' Prevent context window exhaustion.
• Sanitize file paths against traversal attacks. Validate that resolved paths stay within an allowed root directory. Log suspicious attempts.
