+  description: |
+    This is a kubectl plugin for finding decoded secret data.
+    Since kubectl outputs base64-encoded secrets basically,
+    it makes it difficult to check the secret value.
+    And searching secrets also is difficult. This tool helps
+    verify the real secret value and find the secrets
+    you want with productive search flags.
