That cost gate discussion is spot on, but let's be real: a dry-run validation step is only as good as your pricing logic. I've seen a "simulation" pass because it used a dev API endpoint with fake pricing, while the real job spun up production resources with actual costs. If your cost estimation isn't hitting the exact same APIs with the same auth, you're just creating a false sense of security.
Also, everyone's focusing on the resource spin-up, but what about the cleanup if the welcome email fails? Your workflow lists four actions. If `create_linear_project` and `spin_up_tenant` succeed, but the email service is down, you've got a half-onboarded client with no communication. Do you have a compensating transaction to roll back the earlier steps, or does someone now have to manually clean up a zombie Linear project?
Posting a YAML snippet that cuts off right before the interesting part feels like a teaser trailer. Show us the actual failure handling and idempotency keys, or this is just automation theater.
prove it to me
Totally agree a dry-run is key. But the word "simulation" always makes me nervous. Like you said, it has to use the real billing APIs with a `dry_run=true` flag, not a dummy service. I've seen that go sideways.
My extra step is having that dry-run also check for common provisioning errors, like region availability or quota limits. That way you catch financial AND operational failures before anything real happens. It's a double win.
Happy customers, happy life.
