Build More, Build better. Create custom BMad agents, workflows, and domain-specific modules with guided assistance.
BMad Builder (BMB) is a meta-module for BMad Method that helps you create your own agents and workflows. Whether you're building domain-specific expertise or automating repetitive development tasks, BMB guides you through:
- Agent Builder — Create specialized AI agents with custom expertise, communication styles, and tool access
- Workflow Builder — Design structured workflows with steps, menus, and cross-workflow communication
- Module Builder — Package agents and workflows into shareable BMad modules
BMad Builder is installed as a module during BMad Method setup:
npx bmad-method@alpha installSelect BMad Builder from the modules list.
After installing BMad Method with BMB, run from your project root:
/bmb-agent
This launches the Agent Builder workflow that guides you through creating a custom agent.
| Type | Description | Workflow |
|---|---|---|
| Agents | Domain experts with specialized knowledge and tools | /bmb-agent |
| Workflows | Structured processes with steps and decision points | /bmb-workflow |
| Modules | Packaged agents + workflows ready to share | /bmb-module |
You: /bmb-agent
BMB: What domain should this agent specialize in?
You: Blockchain Development
BMB: Great! A blockchain expert would need to know about...
