WHAT IT DOES

What vfx_auto_framing does on vidMagik-mcp

AI agents invoke vfx_auto_framing to trigger actions in vidMagik-mcp. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why vfx_auto_framing needs a policy

This tool performs automated analysis (face/subject detection) and video transformation (cropping and centering). It executes a multi-step process combining computer vision with video editing operations. It modifies video output but is not purely a simple write — it runs detection algorithms and triggers frame transformation logic.
