WHAT IT DOES

What browser_save_pdf does on CoWork OS

AI agents use browser_save_pdf to create or update resources in CoWork OS, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your CoWork OS environment.

RISK

Why browser_save_pdf is rated Medium

The tool creates (writes) a file artifact without permanently destroying data or executing arbitrary code. The action is reversible—saved PDFs can be deleted or overwritten. It does not move money, execute scripts, or irreversibly delete data. Low severity because saving a PDF has minimal blast radius; the worst case is unwanted local file creation, which is easily remediated.

From the tool's definition Tool description states 'Save the current page as a PDF' — this creates a new file (PDF) on the local system.
