Genuinely not trying to be pedantic but deterministic workflows are not what agents do. Indeed they're not capable of them.

You want workflows where the human gates are properly placed, not a "software factory" that you never place eyes on.

That’s sort of, in my opinion, the power of agents that can assist in developing software. The parts that are deterministic are best baked into existing programming paradigms. In some cases it’s good to take the nondeterministic parts we tried to bake into programming languages (often using generic probabilistic means) to outsourcing back to agents. Sometimes even then if the nondeterministic part is well understood and probabilistic methods work (lots of modeling lands here) then leave that in programming paradigms as well.
