On your own, the work moves at the speed you can sit with it. One job at a time, and you read every change before you trust it. A crew moves several jobs at once, and not one of them comes back until a check has proved it. More gets finished in a week, and each finished thing arrives with the check that proves it.
Fleet runs on your own Claude plan, so a whole crew working all day costs the same flat price. A metered agent is a taxi meter. Your plan is a monthly pass. A crew draws on that plan faster than one worker does, and when you hit its limit they wait and pick back up when it resets.
This app is built by its own crew, and on August 18 that crew shipped a fix for a check that could not fail. The check reported success whatever the tests said, and it had marked two workers done while one of them hid thirteen real test failures. A check that reports success without running the tests now counts as a failure, because Fleet reads the real test results itself. You’ve got a list of things you want built. Fleet is the crew that finishes them, and proves each one before it says done.
