Capability routing
Send work to an agent that declares the right skill without hard-coding a process address.
Agent Primitives /Fabric = Durable coordination
Agents that retry after failure.
Discover capabilities, delegate work, and make uncommitted tasks available again after failure. Contracts carry deadlines; workflows carry budgets and compensation.
