Content Guard

This adapter appears to do what it says—redact outbound messages with a local Content Guard scanner—but it relies on a separate Python package that the registry metadata does not declare.

This looks internally coherent for an outbound content-redaction plugin. Before installing, verify that the separate Python package `content-guard` is the one you intend to trust, because this adapter sends every outbound message to that local scanner process. Also note that the default `failOpen: true` means messages will still be delivered unredacted if the scanner fails; set `failOpen: false` if blocking on scanner failure is important.
