What mio_image_compress does on MiOffice — AI-Powered Workspace Studio
AI agents invoke mio_image_compress to trigger actions in MiOffice — AI-Powered Workspace Studio. 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 mio_image_compress is rated High
The tool processes/transforms an image file (compression), which constitutes executing an operation that modifies data in a pipeline. It is not a pure read, nor does it irreversibly delete data or move money. 'Runs in the browser' confirms it triggers an external computational operation. Severity is low since the operation is non-destructive (original is not deleted) and files never leave the device.
From the tool's definition Compress Image — Reduce image file size while maintaining quality. Runs in the browser.
