WHAT IT DOES

What list_xlsx_sheets does on PromptX

AI agents call list_xlsx_sheets to retrieve information from PromptX without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why list_xlsx_sheets is rated Low

This tool queries and returns sheet names from an Excel file, which is a read-only operation with no side effects. It retrieves information about file structure without altering data, executing code, or triggering external operations. The blast radius of misuse is minimal—an agent could only discover sheet names, not access, modify, or delete data.

From the tool's definition Tool name 'list_xlsx_sheets' and description 'List all sheet names in an Excel file' indicate retrieval of metadata without modification or execution.
