“Read that back to me as a plan”
One turn, after a long ramble, that saves whole sessions.
Not filmed yet
The lesson is written out below. The video comes after.
After you have talked for ten minutes about how something should work, do not let it start building. Ask it to reflect the plan back, in order.
What you get is your own thinking with the contradictions exposed. You said the form should be optional and later you said it gates the download. You gave two different rules for the same edge case. Spoken out loud over ten minutes, those sound fine. Listed in order, they are obviously incompatible.
It costs one turn. It routinely saves an entire session of building the wrong thing, which is the most expensive mistake available to you.
The one thing to keep
You will catch your own contradictions immediately.
