Build the Demo, Skip the Deck. Then Delete Half of What You Built.

Build the demo, skip the deck.

Then delete half of what you built.

A few weeks ago I left a comment on Jack Hanlon’s post asking whether AI changes the proposal mechanism itself. If build cost drops to hours, pivot cost drops to hours too. A lot of bad ideas survive only because they are expensive to kill.

I still think that is true.

I just missed the next step.

Then I sat down for a take-home with four hours on the clock and did exactly what I had been arguing for. I planned the best version. CopilotKit for the chat surface. User integrations. Wallet connect. Everything looked sensible on paper.

Then I handed the plan to my agent swarm.

The prototype came back fast.

It also exposed the problem fast.

I had over-scoped it.

That is what the demo is for. Not just persuasion. Calibration.

On paper, almost every feature can sound justified. Each one has a defense. Each one feels additive. A plan is very good at telling you what to include and very bad at telling you what to cut.

Once agents turn the plan into something runnable, the tradeoffs stop hiding. You can finally see what is core, what is optional, and what is just ambition wearing a logic costume.

Agents do not save you from over-ambition. They make it impossible to ignore.

So the loop is three steps.

One. Make the problem legible. Two. Let the agents build the first version. Three. Cut until the scope matches the actual job.

Step one is intent. Step two is execution. Step three is product judgment.

Build the demo, skip the deck, then delete half of what you built. Otherwise speed just finances scope creep.
