Agents that run what they write.

Agents write, run, read the failure, try again. You watch the loop.

1. Watch the loop

   The plan, the diff, the test. Every step lands as it happens.

2. 

   Frontend in the loop

   The browser pane is the agent's too, so it sees what you see.

3. 

   Backend in the loop

   Routes, logs and a terminal the agent can read and rerun.
