The Core Laws
Correct at the first wobble
A wrong path costs more every minute it survives. Interrupt now; it is cheaper than untangling later.
Errors don't wait politely to be noticed. The machine builds fast, and everything it builds after a wrong turn stands on the wrong turn. The correction that costs one word at the first wobble costs a teardown ten minutes later, because by then the wrongness has load-bearing dependents, and the machine will keep reinforcing it with perfect confidence until told otherwise.
So interrupt. Mid-sentence, mid-generation, mid-flow: the instant you see the wrong file, the wrong assumption, the wrong tone, say so, flatly, now. You are not being rude to a machine; you are saving the work. Cushioning the correction with three sentences of politeness costs more than the correction and delivers it later.
How to practice it
Interrupt in motion.
Don't wait for it to finish being wrong. Stopping a generation costs nothing; unwinding its consequences costs the session.
One flat line.
Wrong file, stop. No, the other account. Uncushioned beats polite by ten minutes, and the machine takes no offense.
Don't ride the wrong path.
Letting it run to see where it goes is how one wrong assumption becomes an architecture. You already know where it goes.
Reset when tangled.
If the same correction fails three times, stop correcting. The window is polluted; restart with a better brief instead of a fourth try.
