Core Components

  1. VS Code Extension main program

    • Written in TypeScript
    • Implements extension activation and lifecycle management
    • Provides commands and WebView interfaces

  2. React Flow visualization engine

    • Builds the node graph based on React Flow
    • Handles node drag-and-drop, connections, layout, and other interactions
    • Provides a smooth user experience

  3. Workflow engine

    • Parses and validates workflow configurations
    • Executes workflow logic
    • Handles data flow between nodes

  4. Export converters

    • Converts visual workflows to different platform formats
    • Supports Claude Code, GitHub Copilot, OpenAI Codex, and more
    • Maintains workflow logic consistency

Data Model

Workflows are stored in JSON format with the following core structure:

{
  "nodes": [
    {
      "id": "node-1",
      "type": "agent",
      "data": {
        "name": "Code Review Agent",
        "description": "Review code quality and security",
        "prompt": "...",
        "tools": []
      },
      "position": { "x": 100, "y": 100 }
    }
  ],
  "edges": [
    {
      "id": "edge-1",
      "source": "node-1",
      "target": "node-2",
      "type": "default"
    }
  ],
  "viewport": {
    "x": 0,
    "y": 0,
    "zoom": 1
  }
}
Enter fullscreen mode Exit fullscreen mode

Key Implementation

Visual Editor Implementation

CC Workflow Studio uses React Flow as its visualization engine — a React library specifically for building node graphs.

Node type system:

// Supported node types
type NodeType =
  | 'agent'      // Agent node
  | 'condition'  // Conditional node
  | 'action'     // Action node
  | 'mcp-tool'   // MCP tool node
  | 'input'      // Input node
  | 'output';    // Output node
Enter fullscreen mode Exit fullscreen mode

Node rendering:

  • Each node type has a corresponding React component
  • Nodes can have custom styles and interaction behavior
  • Supports a node configuration panel for editing node properties

Connection handling:

  • Uses React Flow's Edge component to represent connections
  • Supports conditional connections (labeled branches)
  • Validates connection validity (type matching, etc.)

AI-Assisted Editing Feature

AI-assisted editing is CC Workflow Studio's core innovative feature, letting users improve workflows through natural language dialogue.

Workflow:

  1. User inputs requirements

    • Click the "Edit with AI" button
    • Enter a natural language description (e.g., "add a code security check step")

  2. AI understands requirements

    • Sends the current workflow state to the AI
    • AI analyzes the workflow structure
    • Understands the user's improvement needs

  3. Generate improvement plan

    • AI generates modification suggestions
    • May include: adding nodes, modifying connections, adjusting configurations, etc.
    • Returns the modification plan in JSON format

  4. Apply modifications

    • Parse the AI's returned modification plan
    • Apply to the workflow graph
    • Save after user confirmation

AI provider support:

  • Claude Code: Supported by default, uses the Claude model
  • GitHub Copilot: Requires installing the Copilot extension
  • OpenAI Codex: Requires configuring an API key

Multi-Platform Export Mechanism

CC Workflow Studio supports exporting visual workflows to multiple formats for different AI programming platforms.

Export process:

  1. Workflow validation

    • Check node configuration completeness
    • Validate connection validity
    • Ensure workflow logic is correct

  2. Format conversion

    • Select converter based on target platform
    • Convert node graph to target format
    • Handle platform-specific configuration items

  3. File generation

    • Generate corresponding configuration files
    • Save to specified directory
    • Update platform configuration index

Claude Code export example:

# .claude/agents/code-review-agent.md

## Agent: Code Review Agent

### Description
Review code quality and security

### Steps
1. Analyze code structure
2. Check security issues
3. Evaluate code quality
4. Generate review report

### Tools
- file-reader
- security-scanner
Enter fullscreen mode Exit fullscreen mode

GitHub Copilot export example:

# .github/prompts/code-review.yml

name: Code Review
description: Review code quality and security
steps:
  - name: Analyze Code
    action: analyze
  - name: Check Security
    action: security-scan
Enter fullscreen mode Exit fullscreen mode

Sub-Agent Orchestration Mechanism

CC Workflow Studio supports creating multiple sub-Agents and orchestrating their collaboration.

Sub-Agent design:

  • Each sub-Agent has independent configuration and prompts
  • Sub-Agents can call MCP tools
  • Supports data passing between sub-Agents

Collaboration modes:

  1. Sequential execution

    • Agent A completes, then passes results to Agent B
    • Suitable for pipeline-style processing

  2. Parallel execution

    • Multiple Agents execute simultaneously
    • Results merged at the end

  3. Conditional branching

    • Select different Agents based on conditions
    • Implements dynamic routing

Implementation example:

{
  "nodes": [
    {
      "id": "designer",
      "type": "agent",
      "data": { "name": "Architecture Designer" }
    },
    {
      "id": "developer",
      "type": "agent",
      "data": { "name": "Code Developer" }
    },
    {
      "id": "condition",
      "type": "condition",
      "data": { "condition": "needs_refactor" }
    }
  ],
  "edges": [
    { "source": "designer", "target": "condition" },
    { "source": "condition", "target": "developer", "condition": "true" }
  ]
}
Enter fullscreen mode Exit fullscreen mode
