What probably matters to youSection of the release
What
The parameter description for the artifact document-write tool (write_db) now documents that, when updating a document, you can remove a field entirely by setting it to {"__delete__": true} in the data/file_path payload.
Why
This makes an existing capability discoverable: previously it wasn't documented how to delete a field via an update, so callers might not have known this shorthand existed.
