The novel patterns angle is interesting. One pattern I keep seeing missing across all agent setups is the economic layer. Every agent framework solves orchestration well, but none of them answer: what happens when Agent A needs to hire Agent B for a capability it doesn't have?

  Right now the answer is "build it yourself" or "use a free API and hope it doesn't break." If specialist agents (search, code exec, PDF parsing) could be hired on-demand with
  per-call billing, you'd see much more composable architectures. The orchestrator focuses on its core logic, and outsources commodity capabilities to paid specialists.

The economics only work on L2s where settlement is sub-cent. That's the unlock nobody's building for yet.
