How I work

AI agents write much of my code now. I bring one in as soon as I hit a problem, before I've settled on an answer, and describe what's wrong. It often finds a simpler fix than the one I would have steered it toward. When it can't, I know the problem needs my own thinking.

I usually have several pieces of work going at once, each in its own worktree. I come back to one when it's done or stuck, and by then I want it ready to merge or close to it, with the tests passing and a second model's review already dealt with. If an agent keeps stalling in the same place, I give it what it was missing, usually a tool or a way to check its own work.

Some changes will still be wrong, so I make sure each one is quick to undo, and I'll drop an attempt that went the wrong way and start over. I pick languages and models by what gets the job done, and I switch when something better comes along.
