Better page extraction

Could the AI just infer it?

shortest("Generate an API key and use it to execute this cURL request: [placeholder], ensuring the moderation shows up as 'Flagged' in the Moderations table'")

Alternatively, we could have a way of extracting data from a specific shortest (I like the use of Zod you proposed!), something like:

const apiKey = await shortest("Generate an API key").extract( async ({ page }) => {
  schema: z.object({
    apiKey: z.string(),
  }),
});

shortest('Moderate record as bad by using cURL to hit API, ensuring the moderation shows up as 'Flagged' in the Moderations table'', {
  curlCommand: "...",
  apiKey: apiKey,
});

I'm not sure if the code is correct and I think the async page stuff is ugly, but copied from our README.
