I Broke My Multi-Agent Pipeline on Purpose. All 3 Failures Were Silent.

78% of enterprises have at least one AI agent pilot running. Only 14% have successfully scaled one to production. I used to think the gap was about model quality — smarter models, better prompts, more capable agents. After today's experiment, I think the gap is about something much more mundane: what happens between agents. I deliberately broke the handoffs in my 4-agent Content Factory three different ways.
