WHAT IT DOES

What get_material_info does on Kiln

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

RISK

Why get_material_info is rated Low

The 'get_' prefix strongly indicates a query or retrieval operation without side effects. Given the 3D printer management context (OctoPrint, Moonraker, Bambu, etc.), this tool retrieves material properties or status information. The confidence is slightly reduced (0.85 rather than higher) due to the empty description, but the naming convention is sufficiently clear.

From the tool's definition Tool name 'get_material_info' with 'get' prefix indicates a retrieval operation. No description provided to suggest modifications or side effects.
