Built on LangGraph, it uses a multi-agent architecture with three specialized agents: a Manager, Planner, and Programmer with a built-in Reviewer sub-agent. Key features include human-in-the-loop plan review, 'double texting' support for mid-task feedback, isolated Daytona sandboxes for safe code execution, and automatic PR creation. The system runs asynchronously in the cloud, enabling parallel task execution. It was refined using LangSmith for observability and context engineering. The project is fully open source and designed to be extended with custom tools and prompts. ## Full article daily.dev links to this article rather than hosting it.
