WHY IT NEEDS A POLICY

Why editor_save_all needs a policy

This tool creates or modifies data reversibly by saving scene files. While it does not delete data or execute arbitrary code, it commits changes to the filesystem and could overwrite existing scene files. If an AI agent were manipulated into calling this during unintended edits, it could persist unwanted modifications to project files.

From the tool's definition Tool name 'editor_save_all' and description 'Save all open scenes' indicate persistent modification of scene files on disk.
