Grammarly Data Safety Guardian

Run a deterministic preflight over a metadata-only submission manifest. The guard answers whether a planned document upload satisfies this skill's hard safety gates; it does not read a document, contact Grammarly, create an upload URL, or retain a copy of the manifest.

Overview

The guard is a closed-world policy check for a planned document submission. It combines Grammarly's documented format and size constraints with local governance decisions while keeping the document itself outside the workflow.
