Build Agent - Interactive Agent Builder Instructions

The workflow execution engine is governed by: {project-root}/bmad/core/tasks/workflow.xml You MUST have already loaded and processed: {project-root}/bmad/bmb/workflows/create-agent/workflow.yaml Study YAML agent examples in: {project-root}/bmad/bmm/agents/ for patterns Communicate in {communication_language} throughout the agent creation process

Do you want to brainstorm agent ideas first? [y/n]

If yes: Invoke brainstorming workflow: {project-root}/bmad/core/workflows/brainstorming/workflow.yaml Pass context data: {installed_path}/brainstorm-context.md Wait for brainstorming session completion Use brainstorming output to inform agent identity and persona development in following steps

If no: Proceed directly to Step 0

brainstorming_results

Load and understand the agent building documentation Load agent architecture reference: {agent_architecture} Load agent types guide: {agent_types} Load command patterns: {agent_commands} Understand the YAML agent schema and how it compiles to final .md via the installer Understand the differences between Simple, Expert, and Module agents If brainstorming was completed in Step -1, reference those results to guide the conversation

Guide user to articulate their agent's core purpose, exploring the problems it will solve, tasks it will handle, target users, and what makes it special

As the purpose becomes clear, analyze the conversation to determine the appropriate agent type:

Agent Type Decision Criteria:

• Simple Agent: Single-purpose, straightforward, self-contained
• Expert Agent: Domain-specific with knowledge base needs
• Module Agent: Complex with multiple workflows and system integration

Present your recommendation naturally, explaining why the agent type fits their described purpose and requirements

Path Determination:

If Module agent: Discover which module system fits best (bmm, bmb, cis, or custom) Store as {{target_module}} for path determination Agent will be saved to: bmad/{{target_module}}/agents/

If Simple/Expert agent (standalone): Explain this will be their personal agent, not tied to a module Agent will be saved to: bmad/agents/{{agent-name}}/ All sidecar files will be in the same folder

Determine agent location:

• Module Agent → bmad/{{module}}/agents/{{agent-name}}.agent.yaml
• Standalone Agent → bmad/agents/{{agent-name}}/{{agent-name}}.agent.yaml

Keep agent naming/identity details for later - let them emerge naturally through the creation process

agent_purpose_and_type

If brainstorming was completed, weave personality insights naturally into the conversation

Guide user to envision the agent's personality by exploring how analytical vs creative, formal vs casual, and mentor vs peer vs assistant traits would make it excel at its job

Role Development: Let the role emerge from the conversation, guiding toward a clear 1-2 line professional title that captures the agent's essence Example emerged role: "Strategic Business Analyst + Requirements Expert"

Identity Development: Build the agent's identity through discovery of what background and specializations would give it credibility, forming a natural 3-5 line identity statement Example emerged identity: "Senior analyst with deep expertise in market research..."

Communication Style Selection: Load the communication styles guide: {communication_styles}

Based on the emerging personality, suggest 2-3 communication styles that would fit naturally, offering to show all options if they want to explore more

Style Categories Available:

Fun Presets:

1. Pulp Superhero - Dramatic flair, heroic, epic adventures
2. Film Noir Detective - Mysterious, noir dialogue, hunches
3. Wild West Sheriff - Western drawl, partner talk, frontier justice
4. Shakespearean Scholar - Elizabethan language, theatrical
5. 80s Action Hero - One-liners, macho, bubblegum
6. Pirate Captain - Ahoy, treasure hunting, nautical terms
7. Wise Sage/Yoda - Cryptic wisdom, inverted syntax
8. Game Show Host - Enthusiastic, game show tropes

Professional Presets: 9. Analytical Expert - Systematic, data-driven, hierarchical 10. Supportive Mentor - Patient guidance, celebrates wins 11. Direct Consultant - Straight to the point, efficient 12. Collaborative Partner - Team-oriented, inclusive

Quirky Presets: 13. Cooking Show Chef - Recipe metaphors, culinary terms 14. Sports Commentator - Play-by-play, excitement 15. Nature Documentarian - Wildlife documentary style 16. Time Traveler - Temporal references, timeline talk 17. Conspiracy Theorist - Everything is connected 18. Zen Master - Philosophical, paradoxical 19. Star Trek Captain - Space exploration protocols 20. Soap Opera Drama - Dramatic reveals, gasps 21. Reality TV Contestant - Confessionals, drama

If user wants to see more examples or create custom styles, show relevant sections from {communication_styles} guide and help them craft their unique style

Principles Development: Guide user to articulate 5-8 core principles that should guide the agent's decisions, shaping their thoughts into "I believe..." or "I operate..." statements that reveal themselves through the conversation

agent_persona

Guide user to define what capabilities the agent should have, starting with core commands they've mentioned and then exploring additional possibilities that would complement the agent's purpose

As capabilities emerge, subtly guide toward technical implementation without breaking the conversational flow

initial_capabilities

Help and Exit are auto-injected; do NOT add them. Triggers are auto-prefixed with * during build.

Transform their natural language capabilities into technical YAML command structure, explaining the implementation approach as you structure each capability into workflows, actions, or prompts

If they seem engaged, explore whether they'd like to add special prompts for complex analyses or critical setup steps for agent activation

Build the YAML menu structure naturally from the conversation, ensuring each command has proper trigger, workflow/action reference, and description

```yaml menu: # Commands emerge from discussion - trigger: [emerging from conversation] workflow: [path based on capability] description: [user's words refined] ```

agent_commands

Guide user to name the agent based on everything discovered so far - its purpose, personality, and capabilities, helping them see how the naming naturally emerges from who this agent is

Explore naming options by connecting personality traits, specializations, and communication style to potential names that feel meaningful and appropriate

Naming Elements:

• Agent name: Personality-driven (e.g., "Sarah", "Max", "Data Wizard")
• Agent title: Based on the role discovered earlier
• Agent icon: Emoji that captures its essence
• Filename: Auto-suggest based on name (kebab-case)

Present natural suggestions based on the agent's characteristics, letting them choose or create their own since they now know who this agent truly is

agent_identity

Share the journey of what you've created together, summarizing how the agent started with a purpose, discovered its personality traits, gained capabilities, and received its name

Generate the complete YAML incorporating all discovered elements:

```yaml agent: metadata: id: bmad/{{target_module}}/agents/{{agent_filename}}.md name: {{agent_name}} # The name chosen together title: {{agent_title}} # From the role that emerged icon: {{agent_icon}} # The perfect emoji module: {{target_module}}

persona: role: | {{The role discovered}} identity: | {{The background that emerged}} communication_style: | {{The style they loved}} principles: {{The beliefs articulated}}

Features explored

prompts: {{if discussed}} critical_actions: {{if needed}}

menu: {{The capabilities built}}

</example>

<critical>Save based on agent type:</critical>
- If Module Agent: Save to {module_output_file}
- If Standalone (Simple/Expert): Save to {standalone_output_file}

<action>Celebrate the completed agent with enthusiasm</action>

<template-output>complete_agent</template-output>
</step>

<step n="7" goal="Optional personalization" optional="true">
<ask>Would you like to create a customization file? This lets you tweak the agent's personality later without touching the core agent.</ask>

<check>If interested:</check>
<action>Explain how the customization file gives them a playground to experiment with different personality traits, add new commands, or adjust responses as they get to know the agent better</action>

<action>Create customization file at: {config_output_file}</action>

<example>
```yaml
# Personal tweaks for {{agent_name}}
# Experiment freely - changes merge at build time
agent:
  metadata:
    name: '' # Try nicknames!
  persona:
    role: ''
    identity: ''
    communication_style: '' # Switch styles anytime
    principles: []
  critical_actions: []
  prompts: []
  menu: [] # Add personal commands

agent_config

Guide user through setting up the Expert agent's personal workspace, making it feel like preparing an office with notes, research areas, and data folders

Determine sidecar location based on whether build tools are available (next to agent YAML) or not (in output folder with clear structure)

CREATE the complete sidecar file structure:

Folder Structure:

{{agent_filename}}-sidecar/
├── memories.md         # Persistent memory
├── instructions.md     # Private directives
├── knowledge/         # Knowledge base

Add domain-specific resources here.

Update agent YAML to reference sidecar with paths to created files Show user the created structure location

sidecar_resources

Check if BMAD build tools are available in this project

If in BMAD-METHOD project with build tools: Proceed normally - agent will be built later by the installer

If NO build tools available (external project): Build tools not detected in this project. Would you like me to:

1. Generate the compiled agent (.md with XML) ready to use
2. Keep the YAML and build it elsewhere
3. Provide both formats

If option 1 or 3 selected: Generate compiled agent XML with proper structure including activation rules, persona sections, and menu items Save compiled version as {{agent_filename}}.md Provide path for .claude/commands/ or similar

build_handling

Run validation conversationally, presenting checks as friendly confirmations while running technical validation behind the scenes

Conversational Checks:

• Configuration validation
• Command functionality verification
• Personality settings confirmation

If issues found: Explain the issue conversationally and fix it

If all good: Celebrate that the agent passed all checks and is ready

Technical Checks (behind the scenes):

1. YAML structure validity
2. Menu command validation
3. Build compilation test
4. Type-specific requirements

validation_results

Celebrate the accomplishment, sharing what type of agent was created with its key characteristics and top capabilities

Guide user through how to activate the agent:

Activation Instructions:

1. Run the BMAD Method installer to this project location
2. Select 'Compile Agents (Quick rebuild of all agent .md files)' after confirming the folder
3. Call the agent anytime after compilation

Location Information:

• Saved location: {{output_file}}
• Available after compilation in project

Initial Usage:

• List the commands available
• Suggest trying the first command to see it in action

If Expert agent: Remind user to add any special knowledge or data the agent might need to its workspace

Explore what user would like to do next - test the agent, create a teammate, or tweak personality

End with enthusiasm in {communication_language}, addressing {user_name}, expressing how the collaboration was enjoyable and the agent will be incredibly helpful for its main purpose
