csvglow exposes a single tool 'generate_dashboard' with a clear verb-noun name and comprehensive description. The tool has a well-documented input schema with type definitions and parameter descriptions. However, there are notable gaps in error handling, output schema documentation, and security considerations. The description is strong (186 chars, within the 10-1024 baseline), and all parameters have type annotations and descriptions. The main weaknesses are: (1) no documented return schema structure beyond the Python dict shown in code; (2) no error handling guidance for missing files, invalid formats, or filesystem permission issues; (3) no security measures documented for file I/O and browser opening; (4) STDIO-only transport severely limits protocol readiness.
Generate a beautiful, interactive HTML dashboard from a CSV or Excel file. Analyzes the data and produces charts, statistics, correlations, insights, and a sortable data table — all in a single self-contained HTML file. Use this tool when the user wants to visualize, explore, analyze, or create a dashboard from a CSV, TSV, XLS, or XLSX file.
No documented output schema structure. The tool description does not specify what fields are returned or their types. The code shows a simple dict with 'success', 'message', 'output_path' but LLMs need explicit schema documentation to chain tool calls and extract relevant data.
No error handling guidance. Tool description does not explain what happens if: file does not exist, file format is invalid, output path is unwritable, or dashboard generation fails. LLMs need recovery instructions ('If file not found, ask user for correct path') to handle failures gracefully.
Security: open_browser parameter allows arbitrary file system access and may open untrusted files in browser. No discussion of sandboxing, file path validation, or risks. The tool silently opens files without user confirmation.

No validation guidance for file_path parameter. Description does not specify: must file exist before call? Are relative paths allowed? What character encodings are supported? Does tool sanitize paths against traversal attacks (e.g., '../../../etc/passwd')?
Default value 'open_browser: true' may have unintended side effects. Opening a browser automatically could interfere with headless agent execution or user expectations.
