WHY IT NEEDS A POLICY

Why pbir_auto_layout needs a policy

The tool creates or modifies report layout configuration reversibly. It rearranges visual positions but does not delete data, execute external code, trigger financial transactions, or perform irreversible deletions. This is a standard Write operation with minimal blast radius — worst case is a layout change that can be undone by re-running the tool with different parameters or manually adjusting visuals.

From the tool's definition Tool description states 'Auto-arrange all visuals on a page in a grid' — this modifies the layout of existing visuals within a Power BI report (PBIR file). The action is reversible through re-layout or manual repositioning.
