+# @tm/workflow-engine
+
+Enhanced Task Master workflow execution engine with git worktree isolation and Claude Code process management.
+
+## Overview
+
+The Workflow Engine extends Task Master with advanced execution capabilities:
+
+- **Git Worktree Isolation**: Each task runs in its own isolated worktree
+- **Process Sandboxing**: Spawns dedicated Claude Code processes for task execution  
+- **Real-time Monitoring**: Track workflow progress and process output
+- **State Management**: Persistent workflow state across sessions
+- **Parallel Execution**: Run multiple tasks concurrently with resource limits
+
+## Architecture
+
+```
+TaskExecutionManager
+├── WorktreeManager      # Git worktree lifecycle
+├── ProcessSandbox       # Claude Code process management
+└── WorkflowStateManager # Persistent state tracking
+```
+
+## Quick Start
+
+```typescript
+import { TaskExecutionManager } from '@tm/workflow-engine';
+
+const manager = new TaskExecutionManager({
+  projectRoot: '/path/to/project',
+  worktreeBase: '/path/to/worktrees',
+  claudeExecutable: 'claude',
+  maxConcurrent: 3,
+  defaultTimeout: 60,
+  debug: true
+});
+
+await manager.initialize();
+
+// Start task execution
+const workflowId = await manager.startTaskExecution({
+  id: '1.2',
+  title: 'Implement authentication',
+  description: 'Add JWT-based auth system',
+  status: 'pending',
+  priority: 'high'
+});
+
+// Monitor workflow
+const workflow = manager.getWorkflowStatus(workflowId);
+console.log(`Status: ${workflow.status}`);
+
+// Stop when complete
+await manager.stopTaskExecution(workflowId);
+```
+
+## CLI Integration
+
+```bash
+# Start workflow
+tm workflow start 1.2
+
+# List active workflows  
+tm workflow list
+
+# Check status
+tm workflow status workflow-1.2-1234567890-abc123
+
+# Stop workflow
+tm workflow stop workflow-1.2-1234567890-abc123
+```
+
+## VS Code Extension
+
+The workflow engine integrates with the Task Master VS Code extension to provide:
+
+- **Workflow Tree View**: Visual workflow management
+- **Process Monitoring**: Real-time output streaming
+- **Worktree Navigation**: Quick access to isolated workspaces
+- **Status Indicators**: Visual workflow state tracking
+
+## Core Components
+
+### TaskExecutionManager
+
+Orchestrates complete workflow lifecycle:
+
+```typescript
+// Event-driven workflow management
+manager.on('workflow.started', (event) => {
+  console.log(`Started: ${event.workflowId}`);
+});
+
+manager.on('process.output', (event) => {
+  console.log(`[${event.data.stream}]: ${event.data.data}`);
+});
+```
+
+### WorktreeManager
+
+Manages git worktree operations:
+
+```typescript
+import { WorktreeManager } from '@tm/workflow-engine';
+
+const manager = new WorktreeManager({
+  worktreeBase: './worktrees',
+  projectRoot: process.cwd(),
+  autoCleanup: true
+});
+
+// Create isolated workspace
+const worktree = await manager.createWorktree('task-1.2');
+console.log(`Created: ${worktree.path}`);
+
+// List all worktrees
+const worktrees = await manager.listWorktrees();
+
+// Cleanup
+await manager.removeWorktree('task-1.2');
+```
+
+### ProcessSandbox  
+
+Spawns and manages Claude Code processes:
+
+```typescript
+import { ProcessSandbox } from '@tm/workflow-engine';
+
+const sandbox = new ProcessSandbox({
+  claudeExecutable: 'claude',
+  defaultTimeout: 30,
+  debug: true
+});
+
+// Start isolated process
+const process = await sandbox.startProcess(
+  'workflow-123',
+  'task-1.2', 
+  'Implement user authentication with JWT tokens',
+  { cwd: '/path/to/worktree' }
+);
+
+// Send input
+await sandbox.sendInput('workflow-123', 'npm test');
+
+// Monitor output
+sandbox.on('process.output', (event) => {
+  console.log(event.data.data);
+});
+```
+
+### WorkflowStateManager
+
+Persistent workflow state management:
+
+```typescript
+import { WorkflowStateManager } from '@tm/workflow-engine';
+
+const stateManager = new WorkflowStateManager({
+  projectRoot: process.cwd()
+});
+
+await stateManager.loadState();
+
+// Register workflow
+const workflowId = await stateManager.registerWorkflow({
+  taskId: '1.2',
+  taskTitle: 'Authentication',
+  // ... other context
+});
+
+// Update status
+await stateManager.updateWorkflowStatus(workflowId, 'running');
+
+// Query workflows
+const running = stateManager.listWorkflowsByStatus('running');
+```
+
+## Configuration
+
+### Environment Variables
+
+- `TASKMASTER_WORKFLOW_DEBUG`: Enable debug logging
+- `TASKMASTER_CLAUDE_PATH`: Custom Claude Code executable path
+- `TASKMASTER_WORKTREE_BASE`: Base directory for worktrees
+- `TASKMASTER_MAX_CONCURRENT`: Maximum concurrent workflows
+
+### Config Object
+
+```typescript
+interface TaskExecutionManagerConfig {
+  projectRoot: string;           // Project root directory
+  worktreeBase: string;         // Worktree base path  
+  claudeExecutable: string;     // Claude executable
+  maxConcurrent: number;        // Concurrent limit
+  defaultTimeout: number;       // Timeout (minutes)
+  debug: boolean;              // Debug logging
+}
+```
+
+## Workflow States
+
+| State | Description |
+|-------|-------------|
+| `pending` | Created but not started |
+| `initializing` | Setting up worktree/process |
+| `running` | Active execution |
+| `paused` | Temporarily stopped |
+| `completed` | Successfully finished |
+| `failed` | Error occurred |
+| `cancelled` | User cancelled |
+| `timeout` | Exceeded time limit |
+
+## Events
+
+The workflow engine emits events for real-time monitoring:
+
+```typescript
+// Workflow lifecycle
+manager.on('workflow.started', (event) => {});
+manager.on('workflow.completed', (event) => {});
+manager.on('workflow.failed', (event) => {});
+
+// Process events  
+manager.on('process.started', (event) => {});
+manager.on('process.output', (event) => {});
+manager.on('process.stopped', (event) => {});
+
+// Worktree events
+manager.on('worktree.created', (event) => {});
+manager.on('worktree.deleted', (event) => {});
+```
+
+## Error Handling
+
+The workflow engine provides specialized error types:
+
+```typescript
+import { 
+  WorkflowError,
+  WorktreeError, 
+  ProcessError,
+  MaxConcurrentWorkflowsError 
+} from '@tm/workflow-engine';
+
+try {
+  await manager.startTaskExecution(task);
+} catch (error) {
+  if (error instanceof MaxConcurrentWorkflowsError) {
+    console.log('Too many concurrent workflows');
+  } else if (error instanceof WorktreeError) {
+    console.log('Worktree operation failed');
+  }
+}
+```
+
+## Development
+
+```bash
+# Install dependencies
+npm install
+
+# Build package
+npm run build
+
+# Run tests
+npm test
+
+# Development mode
+npm run dev
+```
+
+## Integration Examples
+
+### With Task Master Core
+
+```typescript
+import { createTaskMasterCore } from '@tm/core';
+import { TaskExecutionManager } from '@tm/workflow-engine';
+
+const core = await createTaskMasterCore({ projectPath: '.' });
+const workflows = new TaskExecutionManager({ /*...*/ });
+
+// Get task from core
+const tasks = await core.getTaskList({});
+const task = tasks.tasks.find(t => t.id === '1.2');
+
+// Execute with workflow engine
+if (task) {
+  const workflowId = await workflows.startTaskExecution(task);
+}
+```
+
+### With VS Code Extension
+
+```typescript
+import { WorkflowProvider } from './workflow-provider';
+
+// Register tree view
+const provider = new WorkflowProvider(context);
+vscode.window.createTreeView('taskmaster.workflows', {
+  treeDataProvider: provider
+});
+
+// Register commands
+vscode.commands.registerCommand('taskmaster.workflow.start', 
+  async (taskId) => {
+    await provider.startWorkflow(taskId);
+  }
+);
+```
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Worktree Creation Fails**
+   ```bash
+   # Check git version (requires 2.5+)
+   git --version
+   
+   # Verify project is git repository
+   git status
+   ```
+
+2. **Claude Code Not Found**
+   ```bash
+   # Check Claude installation
+   which claude
+   
+   # Set custom path
+   export TASKMASTER_CLAUDE_PATH=/path/to/claude
+   ```
+
+3. **Permission Errors**
+   ```bash
+   # Check worktree directory permissions
+   chmod -R 755 ./worktrees
+   ```
+
+### Debug Mode
+
+Enable debug logging for troubleshooting:
+
+```typescript
+const manager = new TaskExecutionManager({
+  // ... other config
+  debug: true
+});
+```
+
+Or via environment:
+
+```bash
+export TASKMASTER_WORKFLOW_DEBUG=true
+tm workflow start 1.2
+```
+
+## Roadmap
+
+- [ ] Process resource monitoring (CPU, memory)
+- [ ] Workflow templates and presets
+- [ ] Integration with CI/CD pipelines
+- [ ] Workflow scheduling and queueing
+- [ ] Multi-machine workflow distribution
+- [ ] Advanced debugging and profiling tools
