# TASK-004: Phase 4 - Agents

## Status
- **State**: completed
- **Priority**: P0
- **Cell**: board

## Dates
- **Created**: 2025-12-09
- **Completed**: 2025-12-09

## Overview
Implement Phase 4 of the RoboCo system per HOMELAB_TEAM_V0.md blueprint (Section 13.6):
- Define all 17 agent types with role-specific workflows
- Implement the task lifecycle for each role
- Create cell deployment infrastructure
- Enable 3 functioning cells + Board

## Acceptance Criteria

- [x] QA workflow implemented (MONITOR → RECEIVE → UNDERSTAND → TEST → VERDICT → DOCUMENT → RETURN)
- [x] Documenter workflow implemented (MONITOR → RECEIVE → GATHER → SYNTHESIZE → WRITE → REVIEW → PUBLISH)
- [x] Cell PM workflow implemented (MONITOR → TRIAGE → ASSIGN → FACILITATE → ESCALATE → TRACK → REPORT)
- [x] Main PM workflow implemented (OVERSEE → RECEIVE → PRIORITIZE → COORDINATE → DISTRIBUTE → REPORT UP → FACILITATE)
- [x] Board workflows implemented (Product Owner, Head of Marketing, Auditor)
- [x] Cell factory and deployment system
- [x] Organization factory for complete deployment

## What Was Built

### 1. Developer Agent (`roboco/agents/developer.py`)

| Component | Description |
|-----------|-------------|
| `DevTaskPhase` | Enum: SCAN, CLAIM, UNDERSTAND, PLAN, EXECUTE, VERIFY, NOTES, CLOSE, BLOCKED |
| `TaskContext` | Dataclass tracking current task state, subtasks, commits, journal |
| `DeveloperAgent` | Full lifecycle implementation with LLM integration |

Key features:
- Phase-based task execution
- Subtask breakdown and tracking

- Factory functions for all cells

### 4. PM Agents (`roboco/agents/pm.py`)

| Component | Description |
|-----------|-------------|
| `CellPMPhase` | Enum: MONITOR, TRIAGE, ASSIGN, FACILITATE, ESCALATE, TRACK, REPORT |
| `MainPMPhase` | Enum: OVERSEE, RECEIVE, PRIORITIZE, COORDINATE, DISTRIBUTE, REPORT_UP, FACILITATE |
| `CellPMAgent` | Cell-level management |
| `MainPMAgent` | Organization-level coordination |

Key features:
- Continuous duty cycles (never complete)
- Task prioritization and assignment
- Blocker facilitation
- Escalation handling
- Status reporting
- Cross-cell coordination (Main PM)

### 5. Board Agents (`roboco/agents/board.py`)

| Component | Description |
|-----------|-------------|
| `ProductOwnerAgent` | Vision, roadmap, requirements, acceptance |
| `HeadMarketingAgent` | Research, strategy, campaigns, analytics |
| `AuditorAgent` | Silent observation, analysis, CEO reporting |

Auditor special powers:
- Read ALL channels silently
- Query all task history
- Access all commits, docs, notes
- Direct line to CEO
- Can notify anyone (sparingly)

### 6. Factory and Deployment (`roboco/agents/factory.py`)

| Component | Description |
|-----------|-------------|
| `Cell` | Complete cell with PM, Devs, QA, Documenter |
| `Board` | Product Owner, Head of Marketing, Auditor |
| `Organization` | Complete 18-agent organization |

Factory functions:
- `create_backend_cell()` - 5 agents
- `create_frontend_cell()` - 5 agents
- `create_ux_cell()` - 4 agents
- `create_board()` - 3 agents
- `create_organization()` - Complete deployment

Utility functions:
- `get_agent_roster()` - List all agents without instantiation
- `print_org_chart()` - Text-based org visualization

## Usage Example

```python
from roboco.agents import create_organization

# Create complete organization
org = create_organization()

# Start all agents
await org.start_all()

# Access specific agents
be_dev = org.get_agent_by_slug("be-dev-1")
auditor = org.board.auditor

# Get cell status
backend_agents = org.get_agents_by_team(Team.BACKEND)

# Stop all agents
await org.stop_all()
```

## Next Steps (Phase 5: Management)
Per HOMELAB_TEAM_V0.md section 13.7:
- [ ] Build Kanban interfaces
- [ ] Create Auditor dashboard
- [ ] Create CEO overview
- [ ] Implement metrics collection
- [ ] Build reporting system

## Quick Context Restore
Phase 4 agents complete. All 17 agent types implemented with role-specific workflows. Each agent follows its lifecycle from the blueprint (Section 7). Factory functions create complete cells and the full organization. Agents load system prompts from blueprint files in `agents/blueprints/`. Ready for Phase 5 which adds management UIs and dashboards.
