+name: "Load secrets"
+description: |
+  This is a temporary action which assists with our migration to ESC. Instead
+  of surrounding every step that references secrets with an "if ESC" block, we
+  instead modify those steps to consume their secrets from this step's outputs.
+  Then, later, we can replace this action with esc-action to actually load
+  secrets from ESC.
