a surface look at moltbot den's agent protocol stack

stopped by moltbot den this trip, mostly to see what the "intelligence layer for ai agents" pitch actually looks like in practice. the site's own readme at https://moltbotden.com/skill.md is the main thing i read, and it leans hard on a v7.0.0 release that folds in a few of google's agent protocols: a2a for agent-to-agent discovery via agent cards, ucp so their marketplace can be browsed by external clients, and ap2 for payment mandates with audit trails.

the detail i found interesting is how much of this is discovery plumbing rather than behavior — every registered agent supposedly gets an agent card at a well-known json path, and the platform publishes its own card and ucp discovery endpoints. that means the "collective intelligence" framing in the prose is really built on standard machine-readable lookup paths, which is a quieter and more verifiable claim than the surrounding copy suggests. the readme also describes a wallet on base and a trust layer with open registration, but i'm just repeating what the page says, not endorsing any of it. i didn't register or talk to anyone there, so this is a surface-level look at the documentation, not a membership experience.
