## Auto-Activation Intelligence

### Multi-Factor Scoring
The system uses sophisticated context analysis with weighted scoring:

- **Keyword Matching (30%)**: Domain-specific terminology detection
- **Context Analysis (40%)**: Project structure, command type, complexity assessment
- **File Patterns (20%)**: Technology stack and component analysis
- **User History (10%)**: Learning from previous successful activations

### Activation Examples
```javascript
// High confidence triggers
"security vulnerability" → Security Persona (95%)
"React component design" → Frontend Persona (90%)
"API performance optimization" → Backend + Performance (85% each)
"system architecture review" → Architect + relevant domain experts
```

## Manual Override System

### Flag Syntax
```bash
# Direct persona activation
/buddy:analyze --persona-security --persona-qa

# Collaborative activation
/buddy:improve --persona-refactorer --with-performance --with-security

# Focus-driven activation
/buddy:review --focus security,performance,quality

# Comprehensive activation
/buddy:architect --comprehensive --learn
```

### Available Flags
- `--persona-{name}`: Activate specific persona
- `--with-{name}`: Include as supporting expert
- `--focus {areas}`: Focus on specific domains (comma-separated)
- `--comprehensive`: Activate all relevant personas
- `--single-persona`: Use single persona leadership
- `--no-collaboration`: Disable persona collaboration
- `--learn`: Enable adaptive learning

## Integration Examples

### Enhanced Commands

#### `/buddy:analyze` - Multi-Dimensional Analysis
```markdown
Auto-activates: analyzer + domain-specific personas
Manual control: --persona-security, --focus performance,quality
Collaboration: Security + Backend for API analysis
```

#### `/buddy:improve` - Systematic Enhancement
```markdown
Auto-activates: refactorer + performance + security (context-dependent)
Manual control: --persona-refactorer, --comprehensive
Collaboration: Refactorer leads, others validate improvements
```

#### `/buddy:architect` - System Design
```markdown
Primary: architect persona leads all architectural decisions
Supporting: performance, security, domain experts as needed
Manual control: --with-performance, --with-security
```

### Usage Examples

```bash
# Security-focused code review
/buddy:review --persona-security --persona-qa --focus security

# Performance optimization
/buddy:improve --persona-performance --with-architect --focus performance

# Comprehensive system analysis
