SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill empowers users to extend BMAD's capabilities by creating custom AI agents, workflows, and document templates tailored to specific domains or project needs. It eliminates the limitations of predefined roles and enables true extensibility.

Core Features & Use Cases

  • Custom Agent Creation: Guides the creation of new domain-specific AI agents (e.g., QA Engineer, DevOps Engineer).
  • Custom Workflow Generation: Creates new workflow commands for specialized tasks (e.g., /deploy, /security-audit).
  • Template Customization: Generates custom document templates for various outputs.
  • Use Case: Need a "Security Engineer" agent with specific commands like /security-audit? Use this Skill to define its role, responsibilities, and commands, then generate the necessary files.

Quick Start

Create a new custom agent for a "QA Engineer" role. /create-agent

FAQPage Schema
How do I create custom AI agents for my team's specific workflows?

Custom agent creation automates scaffolding domain-specific AI agents with tailored roles and commands. Define the agent's responsibilities, specify custom workflow commands like `/deploy` or `/security-audit`, and the Skill generates SKILL.md, REFERENCE.md, and supporting scripts conforming to YAML frontmatter standards.

Can I automate the generation of agent documentation and templates?

Yes. The Skill automates creation of token-efficient documentation under 5k tokens, generates SKILL.md and REFERENCE.md files, and provisions script templates and resources. Validation occurs via scaffold-skill.sh and validate-skill.sh to ensure YAML frontmatter conformance.

What's the best way to extend workflow automation across QA, DevOps, and Security teams?

Build domain-specific agents and workflows tailored to each team's needs. The Skill scaffolds skill packages, provisions templates and resources, and enables progressive disclosure of capabilities—allowing QA, DevOps, and Security agents to operate independently with specialized commands.

Do I need to write agents from scratch, or can I use templates?

You don't need to start from scratch. The Skill generates custom document templates and scaffolds skill packages with pre-structured resources. It handles YAML frontmatter conformance and validation automatically, reducing manual setup work.

How do I validate that my custom agent meets documentation and structure requirements?

Validation occurs automatically via scaffold-skill.sh and validate-skill.sh scripts included in the generated agent package. These ensure YAML frontmatter conformance, token efficiency, and that documentation meets the required standards.
