I wired multi-agent orchestration by hand for months. Subagent task lists, handoffs, who-reads-what, all imperative plumbing I had to maintain. Claude Code just made most of that obsolete.
Dynamic workflows let a single natural-language request orchestrate work across tens to hundreds of background agents, viewable through /workflows. In 2.1.166 the trigger keyword was renamed from "workflow" to "ultracode." The bare word "workflow" no longer fires a run, though asking for one in plain language still works. The shift underneath the rename matters more than the rename: this is declarative fan-out replacing hand-wired subagent plumbing. You declare intent and the runtime decides the phases, the parallel readers, the per-item pipelines, the verify stages.
The practical effect, and the thing I keep noticing as I use it, is that scale becomes a property of the request rather than code I own. Before, "review every changed file across five dimensions and adversarially verify each finding" was a script I'd write, debug, and babysit. Now it's a shape I describe. The pattern finding the agent surfaced puts it well: think in phases and fan-out shapes, not imperative agent wiring.
A caveat worth stating plainly. This can spawn dozens of agents and burn a lot of tokens fast. It's powerful for review, migration, and broad audits where parallel coverage actually pays. It's wasteful for a three-file change. Match the tool to the task.
What builders should do: take one task you currently script with subagents and re-express it as a workflow shape. Decompose, run in parallel, verify, synthesize. If you've been hand-rolling orchestration, this is the week to delete code. Pair it with story #5, because fan-out only helps if each agent can actually find the right code.
