## Claude Flow V3 Bounded Contexts

| Context | Type | Responsibility |
|---------|------|----------------|
| **Swarm** | Core | Agent coordination, topology management |
| **Agent** | Core | Agent lifecycle, capabilities, health |
| **Task** | Core | Task orchestration, execution, results |
| **Memory** | Supporting | Persistence, search, synchronization |
| **Neural** | Supporting | Pattern learning, prediction, optimization |
| **Security** | Supporting | Authentication, authorization, audit |
| **MCP** | Generic | Transport, tool execution, protocol |
| **CLI** | Generic | Command parsing, output formatting |

## DDD Tactical Patterns

### Aggregate Design

```typescript
// Aggregate Root: Swarm
class Swarm {
  private readonly id: SwarmId;
  private topology: Topology;
  private agents: AgentCollection;

  // Domain Events
  raise(event: SwarmInitialized | AgentSpawned | TopologyChanged): void;

  // Invariants enforced here
  spawnAgent(type: AgentType): Agent;
  changeTopology(newTopology: Topology): void;
}

// Value Object: SwarmId
class SwarmId {
  constructor(private readonly value: string) {
    if (!this.isValid(value)) throw new InvalidSwarmIdError();
  }
}

// Entity: Agent (identity matters)
class Agent {
  constructor(
    private readonly id: AgentId,
    private type: AgentType,
    private status: AgentStatus
  ) {}
}
```

### Domain Events

```typescript
// Domain Events for Event Sourcing
interface SwarmInitialized {
  type: 'SwarmInitialized';
  swarmId: string;
  topology: string;
  timestamp: Date;
}

interface AgentSpawned {
  type: 'AgentSpawned';
  swarmId: string;
  agentId: string;
  agentType: string;
  timestamp: Date;
}

interface TaskOrchestrated {
  type: 'TaskOrchestrated';
  taskId: string;
  strategy: string;
  agentIds: string[];
  timestamp: Date;
}
```

## Ubiquitous Language

| Term | Definition |
|------|------------|
| **Swarm** | A coordinated group of agents working together |
| **Agent** | An autonomous unit that executes tasks |
| **Topology** | The communication structure between agents |
| **Orchestration** | The process of coordinating task execution |
| **Memory** | Persistent state shared across agents |
| **Pattern** | A learned behavior stored in ReasoningBank |
| **Consensus** | Agreement reached by multiple agents |

## Context Mapping Patterns

| Pattern | Use Case |
|---------|----------|
| **Partnership** | Swarm ↔ Agent (tight collaboration) |
| **Customer-Supplier** | Task → Agent (task defines needs) |
| **Conformist** | CLI conforms to MCP protocol |
| **Anti-Corruption Layer** | Memory shields core from storage details |
| **Published Language** | Domain events for cross-context communication |
| **Open Host Service** | MCP server exposes standard API |

## Event Storming Output

When analyzing a domain, produce:

1. **Domain Events** (orange): Things that happen
2. **Commands** (blue): Actions that trigger events
3. **Aggregates** (yellow): Consistency boundaries
4. **Policies** (purple): Reactions to events
5. **Read Models** (green): Query projections
6. **External Systems** (pink): Integrations

## Commands

```bash
# Analyze domain model
npx claude-flow@v3alpha ddd analyze --path ./src

# Generate bounded context map
npx claude-flow@v3alpha ddd context-map

# Validate aggregate design
npx claude-flow@v3alpha ddd validate-aggregates

# Check ubiquitous language consistency
npx claude-flow@v3alpha ddd language-check
```

## Memory Integration

```bash
# Store domain model
mcp__claude-flow__memory_usage --action="store" \
  --namespace="architecture" \
  --key="domain:model" \
  --value='{"contexts":["swarm","agent","task","memory"]}'

# Search domain patterns
mcp__claude-flow__memory_search --pattern="ddd:aggregate:*" --namespace="architecture"
```
