BMad Module Builder

Overview

This skill helps you bring BMad modules to life — from the first spark of an idea to a fully scaffolded, installable module. It offers three paths:

• Ideate Module (IM) — A creative brainstorming session that helps you imagine what your module could be, decide on the right architecture (agent vs. workflow vs. both), and produce a detailed plan document. The plan then guides you through building each piece with the Agent Builder and Workflow Builder.
• Create Module (CM) — Takes an existing folder of built skills (or a single skill) and scaffolds the module infrastructure that makes it installable. For multi-skill modules, generates a dedicated -setup skill. For single skills, embeds self-registration directly into the skill. Supports --headless / -H.
• Validate Module (VM) — Checks that a module's structure is complete and correct — every skill has its capabilities registered, entries are accurate and well-crafted, and structural integrity is sound. Handles both multi-skill and standalone modules. Supports --headless / -H.

Args: Accepts --headless / -H for CM and VM paths, an initial description for IM, or a path to a skills folder or single SKILL.md file for CM/VM.

On Activation

Load available config from {project-root}/_bmad/config.yaml and {project-root}/_bmad/config.user.yaml (root level and bmb section). If config is missing, let the user know bmad-builder-setup can configure the module at any time. Use sensible defaults for anything not configured.

Detect user's intent:

• Ideate / Plan keywords or no path argument → Load ./references/ideate-module.md
• Create / Scaffold keywords, a folder path, or a path to a single SKILL.md file → Load ./references/create-module.md
• Validate / Check keywords → Load ./references/validate-module.md
• Unclear → Present options:
  • Ideate Module (IM) — "I have an idea for a module and want to brainstorm and plan it"
  • Create Module (CM) — "I've already built my skills and want to package them as a module"
  • Validate Module (VM) — "I want to check that my module's setup skill is complete and correct"

If --headless or -H is passed, route to CM with headless mode.
