An AI coding assistant that can check its own work
An AI coding assistant suggests code while you work. They are genuinely good at it now, and the speed is no longer the interesting part.
Writing is solved, checking is not
A model will produce a function faster than you can type it and it will usually be reasonable. What it cannot do is tell you whether the reasonable-looking version is correct, because nothing in the loop ever ran it against anything that would object.
The wrong answers that survive review
A crash is cheap. It shows up instantly and gets fixed. The costly output is code that runs, returns a plausible number, and is quietly wrong, because it passes a read-through and only fails once someone depends on it. Reviewing your way out of that is slow and unreliable, which is why a source of truth beats a second opinion.
What a live source changes
Point generated code at a real market and correctness stops being a matter of judgement. A price that disagrees with the exchange is visibly wrong. A rate computed with the wrong divisor produces an absurd figure rather than a believable one. The mistake announces itself in seconds instead of surviving into something someone trusts.
What this does not claim
It does not make an assistant better at writing code, and it does not remove the need to read what it produced. It removes one narrow failure: the confident wrong answer that nothing in the process was able to contradict. That is a smaller claim than most tools here make and it is the one worth making.
