If you mostly use Claude as a chat-and-code helper, the easiest mistake is treating Claude Code like "Claude, but stronger." That sounds harmless until you expect a better chat box and run into a different boundary. Core verdict: "Workflow不是多Agent，是把计划写进代码" [C002].
You clicked the news to see whether the model got better. The more useful question is who owns the plan now. If you only read the launch like a raw capability upgrade, you think you bought a stronger version. The hidden cost is worse: you keep using Claude Code and Claude for the same job, and long tasks stay messy.
Dynamic Workflows in Claude Code is the proof point. Anthropic's docs describe the workflow as a JavaScript file Claude writes, where the script decides the next step and stores mid-run results. The May 28, 2026 launch post says that script can drive dozens to hundreds of parallel subagents. That is process logic, not just more chat [C001].
That split matters because chat is great when you want one clean answer. Longer jobs get fragile when the whole plan lives inside the conversation. A file gives the plan a home: you can read it, edit it, save it, and rerun it instead of reconstructing the whole flow from memory.
My practical takeaway is simple. Prompt the workflow you want, then keep the script if the job is worth repeating. Claude Code is better for helping you see the problem; Claude is better for closing out the downstream work. The line worth sharing is not "the model got stronger." It is "the plan stopped living only in chat."
Boundary: no local runtime test here. This is scoped to Anthropic's docs and its May 28, 2026 launch post on Dynamic Workflows in Claude Code. If someone around you is still comparing Claude Code and Claude like they are the same tool with different scores, share this framing.
