An AI agent like Claude Cowork does your task and it feels like magic. But every time it runs, it reasons the whole thing out again, and that costs tokens each time. For a recurring task you pay that thinking bill over and over. Building it once is far cheaper in the long run.
You hand a task to an AI agent like Claude Cowork, and it sorts it out. It reads along, thinks, decides and acts. It feels like magic. So you let it do that task again. And again. Every day.
What I saw
Every run, that agent starts from scratch. It reads everything again, weighs it, decides and acts. That thinking costs tokens, every single time. For a one-off, that’s nothing next to the time you’d spend yourself. But for a task that comes back every day, you pay that thinking bill over and over.
And that’s the sting: the cost grows with how often you run the task, not with how much it earns. The more the agent impresses you, the more you use it, the faster it adds up. For the boring, recurring work you pay the price of original thought every time, while the answer is the same every time.
What I do
For a task that comes back and that we understand, I build it once. The thinking I do with AI, because that’s where it’s strong: finding the pattern, catching the edge cases, writing a first version. But that result I then cast into code. A fixed chain that simply runs. No fresh thinking per run, near-zero cost per run, and it does exactly the same thing every time.
For invoices, declarations and syncs, that “exactly the same every time” is a feature, not a limit. You don’t want an agent there that rethinks it each run and occasionally makes a different call. You want predictable, and you want cheap.
I’m not throwing the AI out, quite the opposite. I use it where it shines: the new, the messy, the judgment calls, the one-offs. For the boring repeat, code wins, on price and on reliability.
A rule of thumb
Does a task come back, and do you understand it well? Build it once. Is it new, messy or rare? Let the AI think it through. The art is in knowing which of the two you’re looking at. And that’s exactly where I’m glad to help you look.
And for you?
Asking an AI the same thing every day? Then maybe that task just needs to be built once, so it runs on its own after that. Let me come and look. The first look is free, no strings.
