technically it looks fine overall.

left some minor comments

+
+    @Parameter(name = ApiConstants.TYPE, type = CommandType.STRING, required = true, description = "Record type (A, CNAME)")


@sudo87
It looks like more record types are supported, right ?
if so, can you update the description ?

weizhouapache · 2026-04-08T09:56:08Z

+        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
+    </properties>


are these properties needed ? @sudo87

other tables too

what about projects and domains ?

+    @Encrypt
+    @Column(name = "api_key")
+    private String apiKey;


the API parameter is credentials, but database column name is api_key

what if there are multiple secrets ? for example both credentials and apikey (just an example) ?
can they be stored in the same column with a separator ?
