  "how": {
    "incantation": "For a JavaScript or TypeScript project using a static scheduled job, define a `type: \"job\"` service with `trigger: \"schedule\"` in `vercel.json` and point it to a file that exports a default function. Deploy it with Vercel; dynamic schedules and local `vc dev` support were not included in this change.",
    "examples": [
      "{\n  \"services\": {\n    \"cleanup\": {\n      \"type\": \"job\",\n      \"trigger\": \"schedule\",\n      \"entrypoint\": \"jobs/cleanup.js\",\n      \"schedule\": \"* * * * *\"\n    }\n  }\n}"
    ],
    "gotchas": [
      "Version: 53.3.0",
      "services.<name>.type (required): Set to `\"job\"` for a scheduled job.",
      "services.<name>.trigger (required): Set to `\"schedule\"` to trigger the job on a schedule.",
      "services.<name>.entrypoint (required): Path to the job file; it must export a default function, invoked once per tick.",
      "services.<name>.schedule (required): Static cron expression for the job schedule.",
      "Prerequisite: Use Vercel CLI 53.3.0 or later for the feature introduced in this release.",
      "Prerequisite: The entrypoint file must export a default function.",
      "Prerequisite: Cron invocations can be secured by setting the project environment variable `CRON_SECRET`; Vercel sends it in the Authorization header. The change's dispatcher verifies it when set.",
      "Docs conflict: The release commit says dynamic schedules and `vc dev` support are future work; they are not available for this feature in the change. https://github.com/vercel/vercel/commit/b4ada64"
