Testing.

Send your own testing agents into the app you’re building. They drive the real running app — not a simulation of it.

The running app,
not a copy of it.

A test against a mock proves the mock works. Your agents open the app itself — the same pages, the same buttons, the same forms a user touches — and report what actually happened.

Each run is a plain sequence of steps — an agent walking the app the way a user would, and writing down what it found.

The regressions you’d find at 2am — the button that stopped responding, the total that rounds wrong — found before the commit lands.

Let an agent find it first.
