List worksheets within an application
AI agents call list_worksheets to retrieve information from HAP MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and lists existing worksheets, which is a read-only query operation. It does not create, modify, delete, execute code, or commit financial transactions. The blast radius is minimal as it only exposes information about worksheet structure.
