The difference between a good episode and a forgettable one is decided before recording, by whether the host has something specific to push on.
An interview where the host agrees with everything is pleasant and unmemorable. The episodes people finish are the ones with a moment of genuine tension, and that moment almost never happens spontaneously.
So the guide names where the guest's public position is contestable and how to press on it. Having it written down is what makes it possible to do warmly, because the host is not improvising a disagreement live.
The host's guide contains research about the guest, including the pushback. Sending that to them is both strange and counterproductive. The guest card carries what they need to prepare: the themes, the shape of the conversation, the practical details.
Some guests send a list. Reordering it or improving it is a reliable way to start a recording badly, so that variant preserves their order and their wording and builds the host's context around it.
Skills compound. These are the ones we usually install alongside it.
