I’ve been using coding agents more lately, and I’ve felt the need to document some of the gems they’ve produced. We’ll start on the sarcastic end of that spectrum. Behold:

+let payload = _.extend({}, form, {
+  name: form.name
+});

 let res = await fetch("/api/foo", {
-  body: JSON.stringify({foo: form}),
+  body: JSON.stringify({foo: payload}),
   method: "POST",
 });

It should be made clear that in the broader program, there is no chance that form will be a non-object. This diff resulted from a seemingly simply and straight-forward prompt of “add a name field to the UI and be sure it’s passed up when the form contents are POSTed to the server.”
