Migration Guide: claude-flow to CleverClaude

This guide helps you migrate from the original TypeScript claude-flow project to the new Python CleverClaude implementation.

📋 Migration Overview

CleverClaude is a complete Python rewrite of claude-flow that preserves all functionality while introducing modern Python patterns, improved architecture, and enhanced features.

Configuration	JSON/JS config	YAML + Environment
Testing	Jest/Mocha	Behave + pytest
Package Management	npm/yarn	uv/pip
Database	Various	PostgreSQL + SQLAlchemy
Caching	Various	Redis
Type System	TypeScript	Python type hints + Pydantic

🚀 Quick Migration Path

1. Environment Setup

# Install CleverClaude
uv pip install cleverclaude

# Or development installation
git clone https://github.com/your-org/cleverclaude.git
cd cleverclaude
uv pip install -e .[dev]

2. Configuration Migration

claude-flow config.json:

{
  "app": {
    "name": "MyApp",
    "port": 8000
  },
  "agents": {
    "maxAgents": 100,
    "defaultTimeout": 300
  },
  "swarm": {
    "defaultTopology": "mesh",
    "maxSwarmSize": 50
  }
}

CleverClaude config.yaml:

app:
  name: "MyApp"
  version: "2.0.0"
  environment: "production"

api:
  host: "127.0.0.1"
  port: 8000

agents:
  max_agents: 100
  default_timeout: 300

swarm:
  default_topology: "mesh"
  max_swarm_size: 50

3. Code Migration Examples

Agent Creation

claude-flow (TypeScript):

import { AgentManager, AgentType } from 'claude-flow';

const manager = new AgentManager(config);
await manager.initialize();

const agentId = await manager.createAgent({
  type: AgentType.RESEARCHER,
  name: "Research Agent",
  capabilities: ["research", "analysis"]
});

CleverClaude (Python):

from cleverclaude import AgentManager, AgentType, settings

manager = AgentManager(settings.agents, session, redis)
await manager.initialize()

agent_id = await manager.create_agent(
    agent_type=AgentType.RESEARCHER,
    name="Research Agent",
    capabilities={"research", "analysis"}
)

Swarm Coordination

claude-flow (TypeScript):

import { SwarmCoordinator, SwarmTopology } from 'claude-flow';

const coordinator = new SwarmCoordinator(config);
const swarmId = await coordinator.createSwarm({
  name: "Analysis Swarm",
  topology: SwarmTopology.HIERARCHICAL
});

await coordinator.addAgent(swarmId, agentId, "worker");

CleverClaude (Python):

from cleverclaude import SwarmCoordinator, SwarmTopology

coordinator = SwarmCoordinator(settings.swarm, session, agent_manager, redis)
swarm_id = await coordinator.create_swarm(
    name="Analysis Swarm",
    topology=SwarmTopology.HIERARCHICAL
)

await coordinator.add_agent(swarm_id, agent_id, role="worker")

MCP Tool Usage

claude-flow (TypeScript):

import { MCPClient } from 'claude-flow/mcp';

const client = new MCPClient();
const result = await client.executeTool('swarm_init', {
  topology: 'mesh',
  maxAgents: 10
});

CleverClaude (Python):

from cleverclaude.mcp import MCPClient

client = MCPClient(settings)
await client.initialize()

result = await client.execute_tool('swarm_init', {
    'topology': 'mesh',
    'maxAgents': 10
})

📚 API Migration

REST API Endpoints

Most REST endpoints remain the same, but with improved response formats:

Endpoint	claude-flow	CleverClaude	Changes
POST /agents	✅	✅	Enhanced error handling
GET /agents/{id}	✅	✅	Additional metadata
POST /swarms	✅	✅	More topology options
POST /swarms/{id}/tasks	✅	✅	Better progress tracking
GET /health	✅	✅	Comprehensive health info
GET /metrics	✅	✅	Prometheus format

WebSocket Events

WebSocket event names and formats remain compatible:

# CleverClaude WebSocket events (compatible with claude-flow)
{
  "type": "agent_created",
  "data": {
    "agentId": "agent_123",
    "type": "researcher",
    "status": "active"
  }
}

{
  "type": "task_completed", 
  "data": {
    "taskId": "task_456",
    "agentId": "agent_123",
    "result": { ... },
    "duration": 1250
  }
}

CLAUDE_FLOW_PORT=8000
CLAUDE_FLOW_DB_URL=postgresql://...
CLAUDE_FLOW_REDIS_URL=redis://...
CLAUDE_FLOW_LOG_LEVEL=info

CleverClaude:

CLEVERCLAUDE_API_PORT=8000

🧪 Testing Migration

Test Framework Changes

claude-flow (Jest):

describe('Agent Manager', () => {
  test('should create agent', async () => {
    const manager = new AgentManager(config);
    const agentId = await manager.createAgent({
      type: 'researcher',
      name: 'Test Agent'
    });
    expect(agentId).toBeDefined();
  });
});

CleverClaude (pytest):

@pytest.mark.async_test
class TestAgentManager:
    async def test_create_agent(self, agent_manager):
        agent_id = await agent_manager.create_agent(
            agent_type=AgentType.RESEARCHER,
            name="Test Agent"
        )
        assert agent_id is not None

CleverClaude (BDD with Behave):

Feature: Agent Management
  Scenario: Create a researcher agent
    Given I have an agent manager
    When I create a researcher agent named "Test Agent"
    Then the agent should be created successfully
    And the agent should be in "active" status

📦 Deployment Migration

  claude-flow:
    build: .
    ports:
      - "8000:8000"
    environment:
      - NODE_ENV=production

    build: .
    ports:
      - "8000:8000"
    environment:
      - CLEVERCLAUDE_ENVIRONMENT=production
    depends_on:
      - redis
      - postgres

  redis:
    image: redis:7-alpine
    
  postgres:
    image: postgres:15
    environment:
      POSTGRES_DB: cleverclaude

🔄 Data Migration

Database Schema Migration

CleverClaude provides migration scripts to convert your existing data:

# Export data from claude-flow
claude-flow export --format json --output claude-flow-data.json

# Import to CleverClaude
cleverclaude import --source claude-flow-data.json --format claude-flow

Manual Data Migration

For custom data structures, use the migration API:

from cleverclaude.migration import ClaudeFlowMigrator

migrator = ClaudeFlowMigrator()

# Migrate agents
await migrator.migrate_agents('path/to/agents.json')

# Migrate swarms  
await migrator.migrate_swarms('path/to/swarms.json')

# Migrate tasks and results
await migrator.migrate_task_history('path/to/tasks.json')

🚨 Breaking Changes

1. Method Naming Convention

claude-flow	CleverClaude	Reason
createAgent()	create_agent()	Python snake_case
addAgent()	add_agent()	Python snake_case
getMetrics()	get_metrics()	Python snake_case

2. Configuration Structure

• Nested configuration now uses YAML hierarchy
• Environment variables use CLEVERCLAUDE_ prefix
• Database URLs require async driver specification

3. Error Handling

# CleverClaude uses structured exceptions
try:
    agent_id = await manager.create_agent(...)
except AgentCreationError as e:
    logger.error(f"Agent creation failed: {e.message}", extra=e.context)
except ResourceLimitError as e:
    logger.warning(f"Resource limit reached: {e.limit_type}")

4. Async/Await Required

All API methods are now async and require await:

# All operations are async
await manager.create_agent(...)
await coordinator.add_agent(...)
await client.execute_tool(...)
