You can now build your own version of Claude Code. Deep Agents is a MIT-licensed framework that recreates the core workflow behind top coding agents. It lets you inspect and modify the exact architecture that makes these agents work. - Planning and todo tools for managing tasks. - File system reading, editing, and shell commands. - Sub-agents for delegating complex, multi-step tasks. - 100% model-agnostic so you can plug in any LLM. 100% open source.
