WHAT IT DOES

What create_document does on CoWork OS

It is a straightforward Write operation that generates formatted files (.docx or .pdf) as requested by the user. There is no execution of arbitrary code, deletion of data, or financial impact. The severity is low because document creation is a common, easily-reversible operation with minimal blast radius.

RECOMMENDED RULE

The rule that runs create_document safely

PolicyLayer is an MCP gateway: it sits between your AI agents and CoWork OS, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For create_document, this is the rule to start with:

create_document Rate-limited

create_document stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
