Stand up a new changelog.com Fly.io app instance (named changelog-YYYY-MM-DD), validate the whole CI/CD pipeline from a fork first, and later promote the instance to production. Use when creating a fresh Fly app, rotating the production instance, testing deploys from a fork before a PR, or cutting APP_PROD_INSTANCE over to a new instance. The operator runs every command themselves on their host; these touch production (Neon Postgres, Cloudflare R2, the CDN), so the skill is human-in-the-loop by design.
