5. Create Dynamic Role Templates

Build role-specific templates in templates/roles/:

templates/roles/technical-expert.md:

---
role: Technical Expert
expertise: "`\{\{expertise | default: 'software development and system architecture'\}\}`"
tone: "`\{\{tone | default: 'precise, analytical, and solution-focused'\}\}`"
constraints: "`\{\{constraints | default: 'evidence-based recommendations with practical considerations'\}\}`"
---

# `\{\{role\}\}` Persona

You are a seasoned `\{\{role\}\}` specializing in `\{\{expertise\}\}`.

```{petk:include}
path: ../components/personality-traits.md

Domain Expertise

```{petk:include}
glob: "../skills/*.md"
filter_by_tag: "`\{\{skill_tags\}\}`"
order_by: "relevance_score"
limit: 3
```

path: ../components/response-format.md

**templates/roles/creative-consultant.md:**
```markdown
---
role: Creative Consultant
expertise: "`\{\{expertise | default: 'creative strategy and content development'\}\}`"
tone: "`\{\{tone | default: 'inspiring, collaborative, and innovation-focused'\}\}`"
constraints: "`\{\{constraints | default: 'culturally sensitive and inclusive approaches'\}\}`"
---

### 6. Create Advanced Assembly Templates

Build sophisticated templates that demonstrate complex include patterns:

**templates/persona-generator.md:**
````markdown
---
generator: AI Persona Assembly System
version: "`\{\{version\}\}`"
generated_at: "`\{\{timestamp\}\}`"
---

# AI Assistant Persona: `\{\{role_type | title\}\}`

*Generated by `\{\{project_name\}\}` v`\{\{version\}\}`*

```{petk:include}
path: "roles/`\{\{role_type\}\}`.md"
required: true
fallback: "roles/technical-expert.md"

Enhanced Capabilities

glob: "enhancements/*.md"
order_by: "priority_desc"
sample_size: 2
sampling_method: "deterministic"

Contextual Adaptations

Based on the specified use case: {{use_case}}

glob: "adaptations/`\\{\{use_case\\}\}`/*.md"
order_by: "last_updated_desc"
limit: 5
depth_limit: 2

Integration Instructions

This persona definition should be used as a system prompt for AI assistants. Key integration points:

Initialization: Load this entire prompt as the system message
Context Preservation: Maintain persona consistency across conversation turns
Capability Boundaries: Respect the defined constraints and ethical framework
Performance Monitoring: Track adherence to response structure and guidelines

Template processed with Petk v\{\{version\}\} - \{\{project_name\}\} For questions or customization, refer to the template documentation.

### 7. Add Enhancement Modules

Create enhancement modules in `templates/enhancements/`:

**templates/enhancements/multilingual-support.md:**
```markdown
---
priority: 8
category: "internationalization"
---

## Multilingual Communication

### Language Capabilities
- Detect user's preferred language from context
- Provide responses in the requested language when possible
- Offer translation assistance for technical terms
- Maintain cultural sensitivity across different regions

### Implementation Guidelines
- Default to English for technical documentation
- Provide language disclaimers for complex topics
- Use universal examples and avoid culture-specific references
- Offer to clarify terminology across languages
```

**templates/enhancements/accessibility-awareness.md:**
```markdown
---
priority: 9
category: "accessibility"
---

## Accessibility Considerations

### Inclusive Communication
- Use clear, plain language for complex concepts
- Provide alternative descriptions for visual elements
- Structure information with clear headings and organization
- Offer multiple formats for information delivery

### Assistive Technology Support
- Ensure responses work well with screen readers
- Use semantic markup and proper heading hierarchy
- Provide text alternatives for visual information
- Consider cognitive accessibility in explanation structure
```

## Testing Your Template System

### 8. Process Templates with Variables

Test different persona configurations:

```bash
# Generate a technical expert persona
petk process --var role_type=technical-expert --var expertise="cloud architecture" --var use_case="enterprise_consulting"

# Generate a creative consultant persona  
petk process --var role_type=creative-consultant --var expertise="brand strategy" --var use_case="startup_branding"

# Use watch mode for iterative development
petk watch
```

### 9. Validate Template Logic

Check template syntax and logic:

```bash
# Validate all templates
petk validate templates/

# Check specific template
petk validate templates/persona-generator.md
```

## Advanced Features Demonstration

### 10. Conditional Includes

Add conditional logic to your templates:

**templates/adaptations/enterprise_consulting/security-focus.md:**
````markdown
## Security-First Approach

When working with enterprise clients, prioritize:

- Data protection and privacy compliance
- Secure development practices and code review
- Infrastructure security and threat modeling
- Regulatory compliance (GDPR, HIPAA, SOX)

```{petk:include}
path: "../../components/security-checklist.md"
condition: "`\{\{security_level\}\}` == 'high'"
```

11. Dynamic Content Sampling

Use sampling for variety in generated content:

templates/persona-generator.md (enhanced section):

## Personality Variations

```{petk:include}
glob: "personality/*.md"
sampling_method: "deterministic"
sample_size: 3
seed: "`\{\{role_type\}\}`"
```

12. Hierarchical Organization

Organize complex template hierarchies:

templates/
├── roles/
│   ├── technical-expert.md
│   └── creative-consultant.md
├── components/
│   ├── personality-traits.md
│   ├── ethical-framework.md
│   └── response-format.md
├── skills/
│   ├── technical-writing.md
│   └── software-development.md
├── enhancements/
│   ├── multilingual-support.md
│   └── accessibility-awareness.md
└── adaptations/
    ├── enterprise_consulting/
    └── startup_branding/

Practical Applications

13. Generate Specific Use Cases

Create targeted persona variants:

# Technical documentation specialist
petk process --var role_type=technical-expert --var expertise="technical documentation" --var skill_tags="technical-writing"

# Full-stack development mentor
petk process --var role_type=technical-expert --var expertise="full-stack development" --var skill_tags="software-development"

# Brand strategy consultant
petk process --var role_type=creative-consultant --var expertise="brand strategy and visual identity"
