+# IPC (Inter-Process Communication)
+
+This package provides IPC functionality for Roo Code, allowing external applications to communicate with the extension through a socket-based interface.
+
+## Available Commands
+
+The IPC interface supports the following task commands:
+
+### StartNewTask
+
+Starts a new task with optional configuration and initial message.
+
+**Parameters:**
+
+- `configuration`: RooCode settings object
+- `text`: Initial task message (string)
+- `images`: Array of image data URIs (optional)
+- `newTab`: Whether to open in a new tab (boolean, optional)
+
+### CancelTask
+
+Cancels a running task.
+
+**Parameters:**
+
+- `data`: Task ID to cancel (string)
+
+### CloseTask
+
+Closes a task and performs cleanup.
+
+**Parameters:**
+
+- `data`: Task ID to close (string)
+
+### ResumeTask
+
+Resumes a task from history.
+
+**Parameters:**
+
+- `data`: Task ID to resume (string)
+
+**Error Handling:**
+
+- If the task ID is not found in history, the command will fail gracefully without crashing the IPC server
+- Errors are logged for debugging purposes but do not propagate to the client
+
+## Usage Example
+
+```typescript
+import { IpcClient } from "@roo-code/ipc"
+
+const client = new IpcClient("/path/to/socket")
+
+// Resume a task
+client.sendCommand({
+	commandName: "ResumeTask",
+	data: "task-123",
+})
+
+// Start a new task
+client.sendCommand({
+	commandName: "StartNewTask",
+	data: {
+		configuration: {
+			/* RooCode settings */
+		},
+		text: "Hello, world!",
+		images: [],
+		newTab: false,
+	},
+})
+```
+
+## Events
+
+The IPC interface also emits task events that clients can listen to:
+
+- `TaskStarted`: When a task begins
+- `TaskCompleted`: When a task finishes
+- `TaskAborted`: When a task is cancelled
+- `Message`: When a task sends a message
+
+## Socket Path
+
+The socket path is typically located in the system's temporary directory and follows the pattern:
+
+- Unix/Linux/macOS: `/tmp/roo-code-{id}.sock`
+- Windows: `\\.\pipe\roo-code-{id}`
