What estimate_support_material does on Kiln
AI agents call estimate_support_material 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.
Why estimate_support_material is rated Low
Based on the name, this tool appears to query/calculate support material parameters (a read-like operation with no side effects). However, confidence is moderate due to the empty description. The sibling tools show a mix of read (ams_status, analyze_*) and write operations (add_*). Without explicit documentation, 'estimate' suggests computation or retrieval rather than modification or execution of printer commands.
From the tool's definition Tool name 'estimate_support_material' and context of 3D printer control suggest it calculates or retrieves support material requirements for a print design. No description provided to confirm.
