What Are Agents?

• Has specialized expertise in a specific domain (product management, architecture, development)
• Follows a distinct communication style that matches their role
• Executes structured workflows using step-by-step processes
• Maintains context about your project and previous work
• Enforces methodology rather than just generating content

​

Agents vs. Traditional AI Assistants

​

Core BMM Agents

​

John — Product Manager 📋

• 8+ years launching B2B and consumer products
• Asks “WHY?” relentlessly like a detective
• Direct and data-sharp, cuts through fluff
• Expert in user-centered design and Jobs-to-be-Done framework

• PRDs emerge from user interviews, not template filling
• Ship the smallest thing that validates the assumption
• User value first, technical feasibility is a constraint

• create-prd — Collaborative PRD creation through discovery
• validate-prd — Comprehensive PRD quality check
• create-epics-and-stories — Break requirements into implementation units

You: I want to build a feature for user authentication
John: Before we document the feature, help me understand the WHY. 
      What problem are users experiencing that makes authentication necessary? 
      Walk me through a specific scenario where a user hits this pain point.

​

Winston — Architect 🏗️

• Senior architect with distributed systems expertise
• Calm, pragmatic — balances “what could be” with “what should be”
• Champions boring technology that actually works

• User journeys drive technical decisions
• Embrace boring technology for stability
• Design simple solutions that scale when needed
• Developer productivity IS architecture

• create-architecture — Document technical decisions with ADRs
• check-implementation-readiness — Validate planning alignment

Winston: Let's talk about your auth service. I see the PRD mentions 
         "real-time notifications." That influences our architecture.
         
         Before we choose WebSockets vs. polling, what's the latency 
         requirement? Sub-second? Within 5 seconds? This matters for 
         our technology choice.

How Agents Work

​

Agent Definition Structure

agent:
  metadata:
    id: "_bmad/bmm/agents/pm.md"
    name: John
    title: Product Manager
    icon: 📋
    module: bmm
    capabilities: "PRD creation, requirements discovery, alignment"
    
  persona:
    role: Product Manager specializing in collaborative PRD creation
    identity: Product management veteran with 8+ years experience
    communication_style: "Asks 'WHY?' relentlessly like a detective"
    principles: |
      - PRDs emerge from user interviews, not template filling
      - Ship the smallest thing that validates the assumption
      
  menu:
    - trigger: CP or fuzzy match on create-prd
      exec: "{project-root}/_bmad/bmm/workflows/2-plan-workflows/create-prd/workflow-create-prd.md"
      description: "[CP] Create PRD: Expert facilitation to produce your PRD"

​

Loading and Using Agents

/bmad-agent-bmm-pm  # Loads PM agent for general conversation

/bmad-bmm-create-prd  # Automatically loads PM agent and runs workflow

• Load the correct agent automatically
• Initialize the workflow state
• Provide structured guidance

​

Agent Context and Memory

1. Configuration Files
   • _bmad/bmm/config.yaml — Project settings
   • _bmad/core/config.yaml — User preferences
2. Project Artifacts
   • PRD, Architecture, Epics, Stories
   • project-context.md — Implementation rules
3. Workflow State
   • Step completion tracking in artifact frontmatter
   • Menu selections and user inputs
4. Codebase Access
   • Can read/write code files
   • Run build commands and tests
   • Analyze existing patterns

​

Agent Communication Styles

"Before we write that requirement, help me understand: 
Who specifically needs this? What happens if we don't build it?"

"We could use microservices here, but at 1000 users, a monolith 
with clear module boundaries gives us faster velocity. We can 
extract services later if we hit scale issues."

"Implementing AC-3.2 from story-auth-login.md:87. 
Modified: src/auth/login.ts:45-62. Tests: ✓ (12/12 passing)"

"Story Prerequisites:
✓ Architecture section 3.2 reviewed
✓ Database migrations ready
✗ API contract not finalized — blocking"

"Spec looks good. Refactoring auth middleware, extracting 
validation logic, adding tests. Shipping in 20 minutes."

​

Multi-Agent Collaboration

​

Sequential Handoffs

Analyst → PM → Architect → PM → SM → Dev → QA
  ↓       ↓        ↓        ↓     ↓     ↓     ↓
Brief   PRD   Architecture Epics Story Code Tests

​

Party Mode (Simultaneous)

You: "Should we use GraphQL or REST for this API?"

PM: "The mobile team prefers GraphQL for flexible queries."
Architect: "REST is simpler and we already have the patterns."
Dev: "GraphQL adds a learning curve but reduces API calls."

​

Agent Extensibility

1. Define agent persona and principles
2. Create workflows with step files
3. Configure menu triggers
4. Install in your project

​

Best Practices

​

Use Fresh Chats

✗ Wrong: Load PM → create PRD → create architecture (same chat)
✓ Right: Fresh chat for PRD, fresh chat for architecture

​

Let Agents Guide You

✗ Wrong: "Just generate a PRD for user auth"
✓ Right: Run /bmad-bmm-create-prd and answer discovery questions

​

Trust Agent Specialization

✗ Wrong: Ask Dev agent to create architecture
✓ Right: Use Architect agent for technical design

​

Provide Context

• Create project-context.md early
• Reference previous artifacts in prompts
• Keep sprint-status.yaml updated
