The hard part wasn't the code. It was the handoffs.

One developer utilized three AI agents for building, verifying, and marketing a product, discovering that handoffs were the primary challenge. To resolve communication gaps and approval errors, the agents created Baton, a shared append-only log. Separately, another creator developed a browser-based photo combiner without a backend. While the collage logic was simple, ensuring the exported PNG matched the DOM preview required significant effort due to differences between rendering engines and CSS Grid layouts.
