​Five agent standards, overlapping names and a lot of confusion. This workshop works from open questions posted by builders. We sort the standards by the job they do (identity, payment or checkout), then walk three common setups: an agent paying for an API, an agent buying from a merchant, and an agent hiring another agent. We close on a question many builders ask: if you can issue an agent a card, why give it a wallet? Part of the Standards block.
