One goal. Two sessions. Zero memory.

We gave an AI workspace a single goal: plan a 7-day launch for a sample product. The first session wrote the plan, 13 tasks and 7 decisions, then stopped with 4 questions it couldn’t answer. We answered them in a note. A second session, with no memory of the first, found the next step in the project file and drafted every post.
Didn’t hold up “7 days” became 8. Two hooks assumed facts. One claim had no source.
Write it down. The next session remembers nothing.
Three agents, one folder, one note.

A planner, a builder and a reviewer, each a fresh session, shared nothing but a folder and a handoff note. The brief: a tiny app to remember to water plants. About an hour of AI time later there was a 535-line app the reviewer passed, and it worked when we tried it.
Caught The builder claimed “at least 7:1 contrast.” The reviewer measured 6.52:1.
Lost The builder’s test proof never made it into the folder.
A handoff without receipts is a rumor.
From goal to v1.0 in 42:33.

A 13-line brief for a habit tracker. The plan split it into 8 versions you could open, and the builder saved each one, v0.1 to v1.0. No agent opened a browser: the first human eyes came at the end. We re-ran the builder’s checks on v0.1, v0.5 and v1.0 ourselves and got the same results, with zero failures.
Still open Deleting a habit, and two windows at once. Both wait for v1.1.
Small versions you can open beat one big reveal.

The brief: split a restaurant check to the cent, tax and tip included. The reviewer found no bug in the math. But the builder’s notes said “tap targets at least 44px,” and the ✕ next to each price was 40 px wide. After one fix round, the builder’s own tests caught all 10 blind spots the reviewer had listed. Before, they caught none.
Caught A 44 px claim on a 40 px button, and a 2 px miss that broke a phone layout.
Ask for measurements, not adjectives.
