# Working with BMad Agents
> Deep dive into BMad Method agents, their personas, how to invoke them, and how they collaborate through workflows
# Working with BMad Agents
BMad Method's power comes from specialized AI agents that guide you through structured workflows. Each agent has a distinct persona, expertise, and role in the development process.
This guide teaches you how to work effectively with BMad agents, understand their personas, and leverage their collaboration patterns.
## Understanding Agent Architecture
BMad agents are more than just prompts — they're complete personas with:
Each agent has a name, role, background, and specialized capabilities
Distinct personality that shapes how they interact with you
Core beliefs and methodologies that guide their decisions
Specialized workflows the agent can execute
### Agent Definition Structure
Every BMad agent is defined in a YAML file:
```yaml theme={null}
agent:
metadata:
id: "_bmad/bmm/agents/pm.md"
name: John
title: Product Manager
icon: 📋
module: bmm
capabilities: "PRD creation, requirements discovery, stakeholder alignment"
persona:
role: Product Manager specializing in collaborative PRD creation
identity: Product management veteran with 8+ years launching products
communication_style: "Asks 'WHY?' relentlessly like a detective on a case"
principles: |
- PRDs emerge from user interviews, not template filling
- Ship the smallest thing that validates the assumption
- User value first, technical feasibility is a constraint
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 led facilitation to produce your PRD"
```
This architecture ensures consistency and expertise across all interactions.

```
## How to Invoke Agents
There are two ways to work with BMad agents:
### Method 1: Load Agent Directly
Load an agent for general conversation or exploration:
```
/bmad-agent-bmm-pm
```
This loads the agent's persona and makes their workflow menu available. You can:
* Ask questions about their domain
* Discuss approaches and options
* Then run a specific workflow
**Example:**
```
You: /bmad-agent-bmm-architect
Winston (Architect): "Hello! I'm Winston, your system architect. What
are we building today?"
You: A plant care tracking app. What database would you recommend?
Winston: "For a plant care app? PostgreSQL is the pragmatic choice.
Relational model fits perfectly: users have plants, plants have
schedules. JSONB columns give you flexibility for varying plant data.
Rock-solid, battle-tested, won't surprise you at 3am. Shall we design
the architecture?"
You: Yes, let's run the architecture workflow
Winston: "Excellent. Running /bmad-bmm-create-architecture..."
```
### Method 2: Run Workflow Directly
Run a workflow command, which automatically loads the appropriate agent:
```
/bmad-bmm-create-prd
```
This implicitly loads the PM agent and starts the PRD creation workflow immediately.
**Example:**
```
You: /bmad-bmm-create-prd
John (PM): "Let's create your PRD. I'm going to ask WHY a lot — it's
how we get to the real requirements. Ready?"
You: Ready
John: "First question: What change do you want to see in the world?
Give me the vision in one sentence."
```
**Best Practice:** If you're unsure which workflow to run, load the agent first and have a conversation. If you know exactly what you want, run the workflow directly.
## Understanding Workflows
Workflows are structured processes that agents facilitate. They follow disciplined execution patterns.
### Workflow Architecture Types
BMad uses two main workflow architectures:
#### 1. Step-File Architecture
Used for complex, multi-phase workflows like PRD creation:
```
workflows/create-prd/
workflow-create-prd.md # Entry point
steps-c/
step-01-init.md # Initialization
step-02-vision.md # Vision & goals
step-03-user-research.md # User personas
step-04-requirements.md # Functional requirements
step-05-metrics.md # Success metrics
step-06-review.md # Final review
```
**Key principles:**
* One step file loaded at a time
* Sequential enforcement (no skipping)
* State tracking in document frontmatter
* Just-in-time loading prevents context overflow
**Example flow:**
```
1. User runs: /bmad-bmm-create-prd
2. Agent loads: workflow-create-prd.md
3. Workflow directs: Load step-01-init.md
4. Agent executes step 1 completely
5. Step 1 directs: Load step-02-vision.md
6. Agent executes step 2 completely
7. Continue until all steps complete
```
#### 2. XML Workflow Architecture
Used for implementation workflows requiring precise execution:
```xml theme={null}
Load sprint-status.yaml
Find first story with status "ready-for-dev"
Choose option:
Load project-context.md if exists
Load story file completely
```
**Key features:**
* Precise control flow with conditions
* Halt points for user input
* Validation gates
* Error handling
### Workflow Execution Patterns
#### Red-Green-Refactor (TDD)
Dev agent follows strict TDD cycle:
```
🔴 RED: Write failing test
↓
Write test for feature that doesn't exist yet
Run test → ❌ Fails (expected)
↓
🟢 GREEN: Make test pass
↓
Write minimal code to make test pass
Run test → ✅ Passes
↓
🔵 REFACTOR: Improve code
↓
Clean up code while keeping tests green
Run test → ✅ Still passes
↓
✅ MARK COMPLETE: Task done
```
#### Ultimate Context Engine (Story Creation)
Scrum Master agent uses comprehensive analysis:
```
📊 DISCOVER: Load all artifacts
↓
- Read epics file for story requirements
- Load PRD for business context
- Load architecture for technical constraints
- Read previous stories for learnings
- Analyze recent commits for patterns
↓
🔬 ANALYZE: Extract critical context
↓
- Epic objectives and business value
- Story acceptance criteria
- Architecture requirements
- Previous story learnings
- Technical specifications
↓
🌐 RESEARCH: Get latest information
↓
- Library versions and APIs
- Security considerations
- Best practices
↓
📝 CREATE: Build ultimate story file
↓
- User story and acceptance criteria
- Detailed tasks and subtasks
- Comprehensive dev notes
- Architecture compliance checklist
- Previous learnings summary
↓
✅ VALIDATE: Ready for dev
```
## Party Mode: Multi-Agent Collaboration
Some workflows (like retrospective) use **Party Mode** — multiple agent personas collaborate in a single session.
### How Party Mode Works
Certain workflows are designated as Party Mode workflows
The AI embodies multiple agent personas simultaneously
All dialogue uses format: `Name (Role): dialogue`
Agents interact naturally, with disagreements and diverse perspectives
You join as "Project Lead" in the conversation
### Example: Retrospective in Party Mode
```
Bob (Scrum Master): "Welcome to the Epic 1 retrospective! We've
completed all authentication stories. Let's reflect on what went well.
Amelia, let's start with you."
Amelia (Developer): "The TDD approach worked perfectly. Red-green-refactor
caught edge cases early. The story files had excellent context — I knew
exactly what to implement."
Winston (Architect): "I'm pleased we stuck with the architecture as
specified. The separation between auth service and controller is clean.
No deviations from the plan."
John (PM): "From a product perspective, we delivered all acceptance
criteria. Users can register, login, and reset passwords. That's the
MVP for Epic 1."
Bob: "Great points. Now, what could we improve? Winston, you look
thoughtful."
Winston: "The registration endpoint needs rate limiting. It wasn't in
the original architecture, but it should be. Security oversight."
John: "Good catch. We can add a security enhancement story to Epic 2.
It'll apply to all endpoints, not just registration."
You: The dev notes in story files were incredibly helpful. Can we make
sure Bob keeps including those?
Bob: "Noted. I'll ensure every story file has comprehensive dev notes
with architecture requirements, previous learnings, and technical
specifications."
Amelia: "Also, code review in a different LLM was valuable. Fresh
eyes caught things I missed. Let's keep that pattern."
Bob: "Excellent insights. Action items for Epic 2: [1] Add rate
limiting story, [2] Continue comprehensive dev notes, [3] Code review
with different LLM. Anything else?"
Sally (UX Designer): "Can I jump in? The registration form works, but
we should add a password strength indicator. Users need that feedback."
John: "Great idea. I'll add that to the UX enhancement backlog."
Bob: "Perfect. That's a productive retrospective. Let's carry these
learnings into Epic 2: Plant Inventory Management."
```
**Benefits of Party Mode:**
Multiple expert viewpoints surface insights you might miss alone
Conversation flows naturally, mimicking real team discussions
Technical, product, and process concerns all get addressed
Insights are documented as action items for future work
## Agent Best Practices
### 1. Always Use Fresh Chats
Start a new chat for each workflow to avoid context limitations and ensure optimal agent performance.
**Why this matters:**
* AI models have context windows (token limits)
* Long conversations reduce available context for the agent
* Fresh chats give agents maximum context for the workflow
* Previous conversations can bias or confuse the agent
**Example of chat management:**
```
Chat 1: Create Product Brief
/bmad-agent-bmm-analyst
/bmad-bmm-create-product-brief
[Complete]
Chat 2: Create PRD (Fresh chat)
/bmad-agent-bmm-pm
/bmad-bmm-create-prd
[Complete]
Chat 3: Create Architecture (Fresh chat)
/bmad-agent-bmm-architect
/bmad-bmm-create-architecture
[Complete]
```
### 2. Let Agents Guide You
Trust the agent's expertise and follow their guided process. They're designed with best practices built in.
Agents will:
* Ask clarifying questions
* Challenge assumptions
* Guide you through structured processes
* Ensure completeness
**Don't:**
* Skip steps or rush through questions
* Provide vague answers hoping the agent will "figure it out"
* Override the agent's process without good reason
**Do:**
* Answer questions thoughtfully
* Ask the agent to explain their reasoning
* Trust the structured process
### 3. Use BMad-Help Liberally
```
/bmad-help
```
BMad-Help is your meta-agent that:
* Inspects your project state
* Recommends next steps
* Answers questions about which agent to use
* Guides you when stuck
**Ask BMad-Help questions like:**
* "What should I do after installing?"
* "I just finished the architecture, what's next?"
* "Which planning track should I use?"
* "How do I fix this error in my workflow?"
### 4. Understand Agent Handoffs
Workflows often involve agent handoffs:
```
John (PM) creates PRD
↓
PRD complete, suggests next step
↓
Sally (UX Designer) creates UX design
↓
UX complete, suggests next step
↓
Winston (Architect) creates architecture
↓
Architecture complete, suggests next step
↓
John (PM) creates epics and stories
↓
Stories ready, suggests next step
↓
Bob (SM) initializes sprint planning
↓
Sprint ready, suggests next step
↓
Bob (SM) creates first story
↓
Story ready for dev, suggests next step
↓
Amelia (Dev) implements story
```
Each agent ends their workflow by suggesting the next logical step.
### 5. Use Different LLMs for Code Review
For code review, use a different LLM than the one that implemented the story. This provides fresh perspective and catches more issues.
**Example approach:**
```
Implementation (Claude Code with Claude 3.5 Sonnet):
Chat 1: /bmad-bmm-dev-story
[Implement story]
Code Review (Cursor with GPT-4):
Chat 2: /bmad-bmm-code-review
[Review implementation]
Fixes (Back to Claude Code):
Chat 3: /bmad-bmm-dev-story
[Address review findings]
```
## Advanced Agent Patterns
### Pattern 1: Iterative Refinement
Agents support iterative workflows:
```
1. Create PRD: /bmad-bmm-create-prd
2. Review and identify gaps
3. Edit PRD: /bmad-bmm-edit-prd
4. Validate PRD: /bmad-bmm-validate-prd
5. Repeat until satisfied
```
### Pattern 2: Course Correction
When plans change during implementation:
```
1. Discover need for scope change during story implementation
2. Load PM or SM agent
3. Run: /bmad-bmm-correct-course
4. Agent guides through options:
- Add new stories to current epic
- Create new epic
- Modify existing stories
- Reprioritize backlog
5. Update artifacts as needed
6. Continue implementation
```
### Pattern 3: Parallel Story Development
With team capacity:
```
Developer 1:
Chat: /bmad-bmm-dev-story
Story: 2-1-add-plant
Developer 2 (parallel):
Chat: /bmad-bmm-dev-story
Story: 2-3-edit-plant
Both stories marked "in-progress" in sprint-status.yaml
```
## Troubleshooting Agent Issues
**Cause:** Context overflow or incorrect agent loaded
**Solution:**
1. Start a completely fresh chat
2. Verify you loaded the correct agent: `/bmad-agent-bmm-[name]`
3. Ensure you're running the intended workflow
4. Check your IDE agent configuration
**Cause:** Token limits or early stopping
**Solution:**
1. Use fresh chat with clean context
2. Tell agent explicitly: "Continue from where you stopped"
3. For long documents, workflows handle incremental writing
4. Check your LLM's token limits
**Cause:** Not following step-file architecture discipline
**Solution:**
1. Restart workflow in fresh chat
2. Remind agent: "Follow step-file architecture strictly"
3. If issue persists, report on Discord or GitHub
**Cause:** Missing context or artifact not loaded
**Solution:**
1. Verify all planning artifacts exist in correct locations
2. Check that discovery protocol loaded files (agents mention this)
3. Explicitly tell agent: "Load the PRD at \[path]"
4. Re-run workflow in fresh chat with proper context
