## 🔄 AGENT SYSTEM EVOLUTION

### Streamlined Architecture (Post-0.9.0)
The agent system has been **simplified** to leverage Claude Code's native Task Tool:

#### Agent Package Status
```python
# claude_pm/agents/__init__.py
"""
This package was previously used for agent implementations but has been
streamlined to use Claude Code's native Task Tool functionality instead.
"""
__all__ = []  # Agent system removed
```

#### Task Tool Integration
- **Native Delegation:** All agent work delegated via Claude Code Task Tool
- **Subprocess Creation:** Direct subprocess agent creation without complex hierarchy
- **Profile Loading:** Agent profiles loaded via `task_tool_profile_integration.py`
- **Registry Integration:** Agent discovery through `AgentRegistry` service

#### Agent Types (Framework Knowledge)
Core agent types for Task Tool delegation:
1. **Documentation Agent** (Documenter)
2. **Ticketing Agent** (Ticketer)  
3. **Version Control Agent** (Versioner)
4. **QA Agent** (QA)
5. **Research Agent** (Researcher)
6. **Ops Agent** (Ops)
7. **Security Agent** (Security)
8. **Engineer Agent** (Engineer)
9. **Data Engineer Agent** (Data Engineer)

### ISS-0118: Agent Registry Implementation
- **Two-Tier Hierarchy:** User agents + System agents (Project tier removed)
- **Directory Precedence:** Current → Parent → User → System
- **Specialized Discovery:** Beyond base agent types
- **Performance Optimization:** <100ms discovery, <50ms loading, <200ms initialization

## 📚 BUSINESS LOGIC DEEP DIVE

### Package Distribution Strategy
The framework uses **NPM as the distribution mechanism** for a Python application:
- **Advantages:** Global installation, dependency management, versioning
- **Challenges:** Mixed JavaScript/Python environment management
- **Solution:** Minimal JavaScript with Python delegation

### Two-Tier Agent Architecture
Simplified from three-tier to two-tier for performance:
- **User Agents:** Filesystem-based, directory precedence rules
- **System Agents:** Code-based, always available as fallback
- **Removed:** Project tier (complexity without benefit)

### Template System Evolution
Framework template management evolved through multiple iterations:
- **CMPM-101:** Deployment detection system
- **CMPM-102:** Versioned template management  
- **CMPM-103:** Dependency management
- **CMPM-104:** Parent directory management (current)

### Memory System Considerations
Memory system disabled due to installation complexity:
- **Technical Debt:** Mem0AI integration caused import failures
- **User Impact:** Installation failures on fresh systems
- **Future Work:** Simplified memory system without external dependencies

## 🎯 DEVELOPMENT PATTERNS

### Service Implementation Pattern
```python
from ..core.base_service import BaseService

class NewService(BaseService):
    """Service description and purpose."""
    
    async def _initialize(self):
        """Service initialization logic."""
        pass
    
    async def _cleanup(self):
        """Service cleanup logic."""
        pass
```

### CLI Command Pattern
```python
@click.group()

def subcommand(flag):
    """Subcommand implementation."""
    pass

def register_new_commands(cli_group):
    """Register commands with main CLI."""
    cli_group.add_command(new_command_group)
```

### Agent Integration Pattern
```python
# Task Tool delegation template
def delegate_to_agent(agent_type, task_description, context):
    """
    **{agent_type} Agent**: {task_description}
    
    TEMPORAL CONTEXT: Today is {current_date}
    
    **Task**: {specific_requirements}
    **Context**: {filtered_context}
    **Authority**: {permissions_scope}
    **Expected Results**: {deliverables}
    """
