WHAT IT DOES

What list_grasshopper_components does on Aos

AI agents call list_grasshopper_components to retrieve information from Aos 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_grasshopper_components is rated Low

The tool appears to retrieve or enumerate Grasshopper components available in Rhino, which is a Read operation with no side effects. While the empty description reduces confidence slightly, the 'list_' prefix is a strong indicator of a retrieval-only operation.

From the tool's definition Tool name 'list_grasshopper_components' indicates retrieval of component metadata or inventory; 'list' is a classic Read operation pattern.
