What does feature-dev do?

feature-dev is a Claude Code plugin that adds the /feature-dev command and three agents: code-explorer, code-architect and code-reviewer. The command runs seven phases. It first clarifies the request, then sends two or three explorer agents to map similar features, architecture and key files. Next it lists open questions and waits for your answers. Architect agents then propose approaches, such as minimal change or cleaner structure, with trade-offs and a recommendation, and you pick one. Claude writes code only after your approval. Three reviewer agents then check simplicity, bugs and project conventions, and a last phase summarizes what was built and why.
