A process is phases, steps, sub-agents and tools

Phases & steps

The unit of work is a step

A process is an ordered set of phases, and each phase holds steps. A step names the sub-agent that performs it, the tools that sub-agent may call, and whether a person signs off before the run continues. Because the structure is explicit, you can change one step without re-testing the whole process.

Flow diagram

One definition, drawn start to end

The same definition, drawn start to end. Operations teams read the diagram; the runtime reads the definition. There is no second model of the process to keep in sync.

Sub-agents & tools

Each sub-agent carries its own model and tools

A cheap model handles classification, a stronger one handles the judgement calls, and neither can reach a tool it was not granted.
