Dynamic workflows — when the harness writes itself

A dynamic workflow is a harness an agent composes on the fly for the task in front of
it, rather than the single fixed harness it normally runs in. Students learn the core
mechanic: from a natural-language request the agent writes an orchestration script,
and a separate runtime executes that script in the background, spinning up tens to
hundreds of parallel subagents whose intermediate results live in script variables
rather than the main context window — so the conversation stays responsive and the
plan stays on track no matter how large the task. The motivating example is a
multi-hundred-thousand-line language port completed in days with the test suite kept
green. This is the harness fundamentals of EB-2 and the orchestrator pattern of EB-7,
now generated automatically and run at scale.
