kumi adds an engineering team to Claude Code, with one coordinator, yui, as your single point of contact. Describe the work in one sentence or a full spec. yui asks about anything left open, states the plan, waits for your go-ahead, and hands each step to the right specialist. Every stack (Go, Angular, iOS, Python, React) has a builder, a debugger and a read-only reviewer. Decisions and progress are saved in the project.
