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

<workflow>

<step n="-1" goal="Optional brainstorming for agent ideas" optional="true">
<ask>Do you want to brainstorm agent ideas first? [y/n]</ask>

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

<check>If no:</check>
<action>Proceed directly to Step 0</action>

<template-output>brainstorming_results</template-output>
</step>

<step n="0" goal="Load technical documentation">
<critical>Load and understand the agent building documentation</critical>
<action>Load agent architecture reference: {agent_architecture}</action>
<action>Load agent types guide: {agent_types}</action>
<action>Load command patterns: {agent_commands}</action>
<action>Understand the YAML agent schema and how it compiles to final .md via the installer</action>
<action>Understand the differences between Simple, Expert, and Module agents</action>
</step>

<step n="1" goal="Discover the agent's purpose and type through natural conversation">
<action>If brainstorming was completed in Step -1, reference those results to guide the conversation</action>

<action>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</action>

<action>As the purpose becomes clear, analyze the conversation to determine the appropriate agent type:</action>

**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

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

**Path Determination:**

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

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

<critical>Determine agent location:</critical>

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

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

</step>

<step n="2" goal="Shape the agent's personality through discovery">
<action>If brainstorming was completed, weave personality insights naturally into the conversation</action>

<action>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</action>

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

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

**Communication Style Selection:**
<action>Load the communication styles guide: {communication_styles}</action>

<action>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</action>

**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

<action>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</action>

**Principles Development:**
<action>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</action>

<template-output>agent_persona</template-output>
</step>

<step n="3" goal="Build capabilities through natural progression">
<action>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</action>

<action>As capabilities emerge, subtly guide toward technical implementation without breaking the conversational flow</action>

<template-output>initial_capabilities</template-output>
</step>

<step n="4" goal="Refine commands and discover advanced features">
<critical>Help and Exit are auto-injected; do NOT add them. Triggers are auto-prefixed with * during build.</critical>

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

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

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

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

<template-output>agent_commands</template-output>
</step>

<step n="5" goal="Name the agent at the perfect moment">
<action>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</action>

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

**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)

<action>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</action>

<template-output>agent_identity</template-output>
</step>

<step n="6" goal="Bring it all together">
<action>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</action>

<action>Generate the complete YAML incorporating all discovered elements:</action>

<example>
```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
````

</example>

<template-output>agent_config</template-output>
</step>

<step n="8" goal="Set up the agent's workspace" if="agent_type == 'expert'">
<action>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</action>

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

<action>CREATE the complete sidecar file structure:</action>

**Folder Structure:**

```

<action>Update agent YAML to reference sidecar with paths to created files</action>
<action>Show user the created structure location</action>

<template-output>sidecar_resources</template-output>
</step>

<step n="8b" goal="Handle build tools availability">
<action>Check if BMAD build tools are available in this project</action>

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

<check>If NO build tools available (external project):</check>
<ask>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
   </ask>

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

<template-output>build_handling</template-output>
</step>

<step n="9" goal="Quality check with personality">
<action>Run validation conversationally, presenting checks as friendly confirmations while running technical validation behind the scenes</action>

**Conversational Checks:**

- Configuration validation
- Command functionality verification
- Personality settings confirmation

<check>If issues found:</check>
<action>Explain the issue conversationally and fix it</action>

<check>If all good:</check>
<action>Celebrate that the agent passed all checks and is ready</action>

**Technical Checks (behind the scenes):**
