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

// 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

// 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

# 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

# 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"
