BMAD Agent Builder

About

The Builder skill is a specialized meta-utility for Claude Code designed to extend and customize the BMAD (Best Model Architecture Design) ecosystem. It empowers users to generate domain-specific agents—such as QA Engineers or Security Specialists—design structured command workflows, and create reusable document templates. By following token-optimized patterns and strict architectural conventions, Builder ensures that new capabilities remain modular, functional, and seamlessly integrated into existing BMAD projects without increasing unnecessary token overhead.
