A build agent that won't let a syntactically broken edit through learned something worth stealing: catch small failures immediately, before they compound into a build nobody can debug. The equivalent for you is scaffolding — breaking a feature into steps small enough that each one is independently checkable before the next begins.
A big feature built in one pass hides its failures until the end, when they're expensive to find. The same feature built in three checkable increments surfaces a bad assumption after step one, not after all three.
Run the seed: take a feature-sized task and break it into 3 increments, each with its own one-line "how I'll know this step worked" check.
