Ten times faster at writing bugs

The agent writes applyDiscount in thirty seconds and it ships. Two weeks later a customer pays minus $12.40. AI shrank the time to write the bug, not the time to find it, and at ten features a day ten bugs wait two weeks each. Reviewing harder is a rubber stamp. Shrink the distance instead: CI, tests and types drag the bug from two weeks to zero seconds, and the agent reads the red test and fixes its own bug.

Brakes: a series on the checks that let an AI coding agent go fast without shipping bugs. Every best practice shortens the time between writing a bug and finding it. Brakes are why race cars go fast. All code is real TypeScript on Node 24, typechecked and tested before it went on screen.
