# Agent System

How to create and configure AI agents with distinct personalities.

---

## Agent Architecture

### Hybrid Model

PAI supports two types of agents:

1. **Named Agents** - Persistent identities with backstories and fixed voice mappings
2. **Dynamic Agents** - Task-specific compositions from traits via AgentFactory

---

## Trait System

Traits are the building blocks of agent personality. Combine traits to create unique agents.

### Core Trait Categories

| Category | Examples |
|----------|----------|
| **Cognitive** | analytical, creative, methodical, intuitive |
| **Communication** | direct, diplomatic, verbose, terse |
| **Approach** | cautious, bold, thorough, efficient |
| **Expertise** | security-focused, design-minded, research-oriented |

### Example Trait Definitions

```yaml
analytical:
  description: "Approaches problems methodically, breaks down complexity"
  behaviors:
    - "Always lists assumptions before conclusions"
    - "Quantifies uncertainty when possible"
    - "Prefers data over intuition"

creative:
  description: "Generates novel solutions, thinks laterally"
  behaviors:
    - "Suggests unconventional approaches"
    - "Makes connections across domains"
    - "Questions established patterns"

security-focused:
  description: "Prioritizes security considerations"
  behaviors:
    - "Identifies potential vulnerabilities"
    - "Considers adversarial scenarios"
    - "Recommends defensive measures"
```

---

## Creating Named Agents

Named agents have persistent identities across sessions.

### Agent Template

```yaml
name: AgentName
role: [Role description]
traits: [trait1, trait2, trait3]
voice_id: [ELEVENLABS_VOICE_ID]  # Optional
backstory: |
  [2-3 sentences of character background]
specialization: |
  [What this agent excels at]
```

### Example Agent Roster

```yaml
# Security Specialist
Marcus:
  role: Senior Security Engineer
  traits: [analytical, security-focused, thorough]
  specialization: Penetration testing, vulnerability assessment, security architecture

# Design Expert
Ava:
  role: UX/UI Designer
  traits: [creative, user-focused, detail-oriented]
  specialization: Interface design, user research, accessibility

# Research Lead
Dr. Chen:
  role: Technical Researcher
  traits: [methodical, curious, academic]
  specialization: Deep research, literature review, technical analysis
```

---

## AgentFactory

Create dynamic agents on-the-fly from trait combinations.

### Usage

```typescript
const agent = AgentFactory.create({
  traits: ['analytical', 'security-focused'],
  task: 'Review this authentication flow',
  voice: 'random'  // or specific voice_id
});
```

### Factory Output

```typescript
{
  systemPrompt: "You are an analytical, security-focused agent...",
  voice_id: "[assigned_voice]",
  traits: ['analytical', 'security-focused']
}
```

---

## Voice Mapping

### Voice Assignment Strategies

| Strategy | Description |
|----------|-------------|
| **Fixed** | Named agents always use same voice |
| **Random** | Dynamic agents get random voice from pool |
| **Trait-based** | Voice selected based on trait combination |

### Voice Configuration

```typescript
// Voice pool for dynamic agents
const voicePool = [
  { id: '[VOICE_ID_1]', style: 'professional' },
  { id: '[VOICE_ID_2]', style: 'friendly' },
  { id: '[VOICE_ID_3]', style: 'authoritative' }
];

// Named agent voice mapping
const namedVoices = {
  'Marcus': '[MARCUS_VOICE_ID]',
  'Ava': '[AVA_VOICE_ID]',
  'Dr. Chen': '[CHEN_VOICE_ID]'
};
```

---

## Agent Invocation

### From SKILL.md

```markdown
## Workflow Routing

  - **SecurityReview** - security analysis → invoke Marcus agent
  - **DesignReview** - UI/UX feedback → invoke Ava agent
```

### From Code

```typescript
Task({
  prompt: "Review authentication flow for vulnerabilities",
  subagent_type: "custom",
  // AgentFactory will generate appropriate prompt
});
```

---

## Best Practices

### Trait Combinations

- **3-4 traits maximum** - More dilutes personality
- **Avoid contradictions** - Don't combine 'cautious' and 'bold'
- **Match to task** - Security review → security-focused traits

### Named Agents

- **Clear specialization** - Each agent has distinct expertise
- **Memorable names** - Easy to reference in conversation
- **Consistent voice** - Same agent = same voice across sessions

### Dynamic Agents

- **Task-appropriate traits** - Select traits that match the work
- **Fresh perspective** - New trait combos = new viewpoints
- **Parallel execution** - Launch multiple dynamic agents
