What it is

Seed data is pretend content: sample customers, orders, and messages that fill an empty app so you can see how it looks and behaves. It's how you review a dashboard before anyone has used it.

Good seed data is realistic: plausible names, believable amounts, a mix of statuses, some edge cases (a very long name, an empty field). "Test 1, Test 2" hides layout problems.

It's also useful to have a version with no data at all, to check the empty states.

How to ask for it

Vague

“I can't tell what it looks like because it's empty.”

Precise

“Add seed data: 12 realistic clients with a mix of active, paused, and churned statuses, 40 invoices across the last six months, one client with a very long company name, and a separate empty scenario.”

Why it works

The weak prompt states the problem; "seed data" names the fix and the prompt sets quantity, realism, and edge cases.
