Devstral Vibe Sidebar Extension for VS Code

This VS Code extension integrates Devstral Vibe CLI directly into your VS Code sidebar, allowing you to interact with Vibe without leaving your editor. The fist version 0.0.1 was based on Claude Code Sidebar by Rudi Wahyudi and was also using node-pty an, xcode and xterm.js. Version 0.0.2 changed to use the default VSCode terminal which is a lot more lightweight and straightforward.

Features

• Sidebar Integration: Adds a Devstral Vibe icon to the VS Code activity bar
• VSCode Terminal: Opens a standard VSCode shell terminal (zsh/bash/etc.) to the right of your current editor and loads the Vibe CLI.
• Auto-start Vibe: Automatically runs the vibe command when the terminal opens
• Auto Cleanup: Automatically closes the Vibe session when VS Code exits or restarts
• Full Terminal Support: Full terminal capabilities with proper PTY support using node-pty

Prerequisites

Before installing this extension, make sure you have:

1. VS Code (v1.85.0 or higher) - Download here
2. Devstral Vibe CLI installed and accessible in your PATH
   • Install with: curl -LsSf https://mistral.ai/vibe/install.sh | bash
   • You can verify this by running vibe --version in your terminal
   • For more information, see Devstral Vibe documentation

Installation

Step 1: Clone or Download the Repository

git clone https://github.com/proudcommerce/devstral-vibe-sidebar
cd devstral-vibe-sidebar

Step 2: Install Dependencies

npm install

npm run rebuild

Step 3: Compile the Extension

npm run compile

This will compile the TypeScript code to JavaScript in the out directory.

Step 4: Install the Extension Locally

There are two ways to install the extension locally:

Option A: Using the Extension Development Host (Recommended for Testing)

1. Open the extension folder in VS Code:

   code .
   

2. Press F5 or go to Run > Start Debugging

3. This will open a new VS Code window with the extension loaded

4. In the new window, you should see the Devstral Vibe icon in the activity bar (sidebar)

Option B: Package and Install (Recommended for Regular Use)

1. Install the vsce tool if you haven't already:

   npm install -g @vscode/vsce
   

2. Package the extension:

   vsce package
   

   This creates a .vsix file (e.g., devstral-vibe-sidebar-0.0.2.vsix)

3. Install the packaged extension:

   • Open VS Code
   • Go to Extensions view (Ctrl+Shift+X or Cmd+Shift+X)
   • Click the ... menu at the top
   • Select Install from VSIX...
   • Choose the .vsix file you just created

4. Reload VS Code when prompted

Usage

Opening Devstral Vibe

1. Click the Devstral Vibe icon above your current editor window
2. A terminal will open in the sidebar (your default shell: zsh, bash, etc.)
3. The extension automatically runs vibe command for you
4. You can now interact with Devstral Vibe directly in the terminal

Keyboard Shortcut

• Windows/Linux: Ctrl+Alt+V
• macOS: Cmd+Alt+V

Interacting with Vibe

• Type directly in the terminal - it's a real terminal with full functionality
• Use all Vibe commands and features as you normally would
• Use slash commands for configuration adjustments
• The terminal supports all standard terminal operations (copy, paste, keyboard shortcuts, etc.)

Closing Devstral Vibe

The terminal and Vibe session will automatically close when:

• You close VS Code
• You reload VS Code window (Ctrl+R or Cmd+R)
• The extension is deactivated

You can also manually exit Vibe by typing exit or pressing Ctrl+D, then close the sidebar panel.

Troubleshooting

Extension doesn't appear in the sidebar

• Make sure the extension is installed correctly
• Try reloading VS Code (Ctrl+R or Cmd+R)
• Check the Output panel (View > Output) and select "Devstral Vibe Sidebar" for error messages

"vibe is not found" or similar error

• Ensure the vibe command is in your system PATH
• Try running vibe --version in your regular terminal
• If it doesn't work, reinstall Vibe CLI: curl -LsSf https://mistral.ai/vibe/install.sh | bash

Terminal shows errors or doesn't respond

• Check if Vibe CLI is working correctly outside VS Code
• Look at the VS Code Developer Console (Help > Toggle Developer Tools) for error messages
• Make sure you have the latest version of Vibe installed

Vibe process doesn't close properly

• The extension tries to clean up automatically, but if you notice lingering processes:
  • Check running processes: ps aux | grep vibe
  • Manually kill if needed: kill <process-id>
