Software is built differently now. So is learning it.

AI writes more of the code. The people who understand the system matter more than ever.

orders.ts · proposed by the agent

// Fix: customers can order sold-out items
async function placeOrder(cart) {
  const stock = await getStock(cart.sku)
-  if (stock > 0) await db.save(cart)+  if (stock < cart.qty) throw new SoldOut()+  await db.orders.insert(cart)+  await db.stock.decrement(cart.sku)  return { ok: true }
}

The job is judgment.

Learn what’s real.

You work on real software for a real business, with real constraints, the way teams do.

The email goes out, but sometimes the order never saves.

You’re close. Let’s look at it another way.

What should the customer wait for, and what can happen later?

Your pace. Prove it, then move on.

Progress follows what you can show you can do, not the calendar.

You’ll build AI agents.

Agents are software. We teach you to build them properly. Read how we think about it →

Give your software hands.

You expose your app’s actions as tools. The agent uses them.

tools.ts

export const tools = [{
  name: "getOrder",
  input: z.object({ id: z.string() }),
  run: ({ id }) => db.orders.find(id)
}, {
  name: "issueRefund",
  input: z.object({
    id: z.string(), amount: z.number()
  }),
  run: refund
}]
