Pointing an AI at an API takes an afternoon. Knowing what it must never do takes a career.
Knowing the API is the easy part
These are the rules that separate a demo from something you let near production. None of them is advice the agent hands you — it is how it behaves, every time, on every account.
Saved is not publishedA container version that exists is not a version that is live. Blurring those two is how a Friday deploy becomes a Monday incident.
purchase is already a key eventMarking it again looks like progress and changes nothing. The finding worth having is which properties never sent begin_checkout at all.
Budgets spend the moment they landAdvertising changes are not configuration — they are money. New campaigns start paused, and anything that moves spend waits for your word.
Every API has a ceilingBulk work that ignores quotas dies at the tenth account and leaves the other thirty half-done. Long jobs are paced to finish, and say where they stopped.
A query is an invoiceScanning a year of event data to answer one question is a lesson you only pay for once. Reads are scoped before they are run.
Archived, removed, deletedThree words, three very different futures. Which one you are about to trigger is said out loud before it happens, not discovered afterwards.
It executes, not just advisesAnything the official Google APIs can do, done for you in your accounts — not explained to you in a list of steps.
Built for fleetsOne message can audit or update dozens of properties and containers. You approve, it applies, and every change is logged.
Your accounts stay yoursRuns on your own Google Cloud project — your quotas, your logs, your bill. Read-only until you decide otherwise, revocable in one click.
