How 75 AI Agents Collaborate: My Five-Layer Evolution

Someone asked me: “You’ve got 75 AI agents (as of mid-July, counting both active and experimental ones). How do they actually interact? When Agent A finishes something, how does Agent B pick it up?” Great question. Because I didn’t have a clue at the start either. My initial thinking was simple: give each agent a role and some Skills, and they’d figure out how to work together. Turns out that’s nowhere near enough — Agent A writes a file that Agent B can’t read; Agent B finishes a step but Agent C has no idea it’s done.
