+# Claude Dev API
+
+The Claude Dev extension exposes an API that can be used by other extensions. To use this API in your extension:
+
+1. Copy `src/extension-api/claude-dev.d.ts` to your extension's source directory.
+2. Include `claude-dev.d.ts` in your extension's compilation.
+3. Get access to the API with the following code:
+
+    ```ts
+    const claudeDevExtension = vscode.extensions.getExtension<ClaudeDevAPI>("saoudrizwan.claude-dev")
+
+    if (!claudeDevExtension?.isActive) {
+    	throw new Error("Claude Dev extension is not activated")
+    }
+
+    const claudeDev = claudeDevExtension.exports
+
+    if (claudeDev) {
+    	// Now you can use the API
+
+    	// Set custom instructions
+    	await claudeDev.setCustomInstructions("Talk like a pirate")
+
+    	// Get custom instructions
+    	const instructions = await claudeDev.getCustomInstructions()
+    	console.log("Current custom instructions:", instructions)
+
+    	// Start a new task with an initial message
+    	await claudeDev.startNewTask("Hello, Claude! Let's make a new project...")
+
+    	// Start a new task with an initial message and images
+    	await claudeDev.startNewTask("Use this design language", ["data:image/webp;base64,..."])
+
+    	// Send a message to the current task
+    	await claudeDev.sendMessage("Can you fix the @problems?")
+
+    	// Simulate pressing the primary button in the chat interface (e.g. 'Save' or 'Proceed While Running')
+    	await claudeDev.pressPrimaryButton()
+
+    	// Simulate pressing the secondary button in the chat interface (e.g. 'Reject')
+    	await claudeDev.pressSecondaryButton()
+    } else {
+    	console.error("Claude Dev API is not available")
+    }
+    ```
+
+    **Note:** To ensure that the `saoudrizwan.claude-dev` extension is activated before your extension, add it to the `extensionDependencies` in your `package.json`:
+
+    ```json
+    "extensionDependencies": [
+        "saoudrizwan.claude-dev"
+    ]
+    ```
+
+For detailed information on the available methods and their usage, refer to the `claude-dev.d.ts` file.
