Every boundary you draw removes a signal your tooling was relying on. That is a structure problem, not a search problem.

RAG retrieves. Agents act. I built both separately, connected them explicitly, and ran the same nine tasks through all three systems.

I tested TypeSafe AI’s Jev on 3,080 classification tasks to see how its accuracy, latency, calibration, and confidence compare with LLMs — and whether it works as a practical decision layer for AI systems.

Multi-agent coding systems don't necessarily fail because agents can't communicate. They can fail because important commitments made in conversation have nowhere to live afterward.
