WHY IT NEEDS A POLICY

Why results_export_image needs a policy

This tool exports simulation results as image files, which is a write operation that creates new data artifacts. It does not delete data (Destructive), execute arbitrary code (Execute), trigger financial transactions (Financial), or permanently alter simulation state.

From the tool's definition Tool name 'results_export_image' indicates writing/exporting image output from simulation results. The empty description limits confidence, but 'export' suggests creating and potentially saving a file artifact.
