Did the app break,
or did the tests go stale?

The controls

You name the control once

Twenty controls, each taking the name you'd use out loud. That name is what makes the report readable by someone who never opens the code — and it's the same name razo later matches against the diff. Write your tests with plain Playwright calls and you get a stack trace like any other run.

await new Input(page, 'email', 'Email').fill('ada@example.com');
await new Table(page, 'items', 'Cart items').expectRowCount(2);
await new Button(page, 'place-order', 'Place order').click();

razo writes the sentence

1. Type "ada@example.com" into field "Email"
2. Assert table "Cart items" has 2 rows
3. Click button "Place order"

and records it

{
  "action": "click",
  "controlType": "button",
  "name": "Place order",
  "selector": "[data-testid=\"place-order\"]",
  "status": "failed"
}

The payoff

Matched against the diff

Because the artifact records the control by name, razo can line up what the test touched with what the pull request changed. That intersection is the whole verdict — and it needs a named control to exist at all.

button "Place order"

- <button data-testid="place-order">+ <button data-testid="place-order" style="display:none">
