Claude Code is Anthropic’s coding agent, built around Claude models and a more integrated command-line workflow. The biggest practical difference is control: Deep Agents gives you more choices to configure; […]

Overlap independent work: prefetching can reduce visible startup delays. Separate responsibilities: orchestration and deferred work provide reusable design lessons. When you type claude into your terminal, there is a highly sophisticated Claude Code […]
