+      description: |
+        Add support for the REQUEST_DIAGNOSTICS action.
+        When this action is recieved the agent will collect a diagnostics bundle and
+        upload it to fleet-server using the file upload APIs.
+        The handler has a configurable rate limit in order to prevent DoS attacks.
+        The uploader may retry failures with a configurable exponential backoff.
