build_parametric_prompt · Kiln MCP: Risk & Policy

WHAT IT DOES

What build_parametric_prompt does on Kiln

AI agents call build_parametric_prompt as a supporting operation in Kiln workflows.

WHY IT NEEDS A POLICY

Why build_parametric_prompt needs a policy

With no description available, classification relies solely on the tool name. 'build_parametric_prompt' implies assembling or generating a prompt (likely text), which is a low-risk read/write operation at most. Given the 3D printing context, it may construct a prompt for AI-assisted design, but no destructive, financial, or execute-level risk is apparent. Confidence is low due to the empty description.

From the tool's definition Tool description is empty and uninformative; name 'build_parametric_prompt' suggests constructing a prompt string parametrically, which is a read/prepare operation with no clear side effects.
