Schema suggestions — Run a review
Open Schema & relations from Manage workspace and choose ✦ Schema suggestions. The review reads your tables, your fields and a sample of the values in them, then proposes changes. It takes around half a minute and narrates what it is doing as it goes, because most of that time is spent measuring your data rather than waiting on the model.
It counts against your workspace's AI allowance, so it runs only when you ask for it — never on page load, and never on a schedule.
An empty result is a real answer. If the review finds nothing worth changing it says so, rather than inventing something to justify the trip.
