WHY IT NEEDS A POLICY

Why animate_to_youtube needs a policy

The tool performs a multi-step pipeline (rig humanoid model → animate → render → upload to YouTube) that results in new content being posted to an external platform. This is a Write operation because it creates new data (video uploads) on YouTube, which is reversible via manual deletion. It is not Destructive (no deletion) or Execute (not arbitrary code execution—the operations are specific and bounded).

From the tool's definition Tool directly uploads generated/animated content to YouTube (indicated by 'to_youtube' naming and description stating 'uploading them directly to YouTube'). This creates new content on a user's YouTube channel without deletion or reversal of prior state.
