This is actually very interesting I think, as Anthropic pushes against The Bitter Lesson a bit! The model is a great reasoner, but we still need a concrete way to manage tasks - like we needed for tool calling. Claude Code has an opinionated loop, something like ReAct/CoT etc with prompting tricks for tasks/skills/etc, but here they add a Hierarchical Controller/Worker thing leveraging the Claude SDK. Mixing agency with actual control using program logic - not just alignment using prompts screaming in all caps and emoji.

We are going to break out of the coding agent’s loop in this way - it’s sorta curving back around to Workflows, after leaving them behind for agency, but right now we need to orchestrate this with deterministic code written mostly by humans - like the git repo anthropic shared. This won’t last long.
