Step-by-Step Instructions

Install the Claude for VS Code Extension

Open VS Code and navigate to the Extensions view by clicking the Extensions icon in the Activity Bar or pressing Ctrl+Shift+X. Search for Claude for VS Code by Anthropic in the marketplace. Click Install on the official extension.

Make sure to install the official extension by Anthropic to ensure security and proper functionality.

Get Your Claude API Key

Visit console.anthropic.com and log into your Claude account. Navigate to API Keys in the left sidebar. Click Create Key and give it a descriptive name like VS Code Integration. Copy the generated API key immediately as it won't be shown again.

Store your API key securely and never share it publicly or commit it to version control.

Configure the Extension Settings

In VS Code, open Settings by pressing Ctrl+, or going to File > Preferences > Settings. Search for Claude in the settings search bar. Find the Claude: API Key setting and paste your API key. Set your preferred model version in the Claude: Model dropdown.

Consider using Claude-3.5-Sonnet for the best balance of performance and cost for coding tasks.

Activate Claude in Your Workspace

Open a code file or create a new one in VS Code. Look for the Claude icon in the Activity Bar on the left side. Click it to open the Claude panel. You should see a welcome message confirming the connection. Test the setup by typing a simple coding question in the chat interface.

Configure Code Context Settings

In the Claude panel, click the Settings gear icon. Enable Auto-include open files to automatically provide context from your current files. Set the Max context files to your preferred number (recommended: 5-10). Toggle Include file tree if you want Claude to understand your project structure.

Enabling more context helps Claude provide better suggestions but may increase API usage costs.

Set Up Keyboard Shortcuts

Go to File > Preferences > Keyboard Shortcuts or press Ctrl+K Ctrl+S. Search for Claude to see available commands. Set shortcuts for frequently used actions like Claude: Ask about selection and Claude: Explain code. Common shortcuts include Ctrl+Shift+C for quick chat.

Customize shortcuts based on your workflow - having quick access to Claude's features will improve your productivity.

Test Integration Features

Select some code in your editor and right-click to see Claude options in the context menu. Try Ask Claude or Explain this code. Test the inline suggestions by typing comments like // TODO: create a function to validate email and see if Claude offers to generate code.

Experiment with different types of requests to understand Claude's capabilities within your coding workflow.

Common Issues & Troubleshooting

Extension shows 'API key invalid' error

Double-check your API key in VS Code settings. Ensure you copied the complete key from the Anthropic console and that your account has API access enabled. Try generating a new API key if the issue persists.

Claude responses are slow or timing out

Check your internet connection and reduce the number of context files being included. Go to Claude settings and lower the Max context files setting. Consider switching to a faster model like Claude-3-Haiku for quicker responses.

Claude panel not appearing in Activity Bar

Restart VS Code after installing the extension. If still missing, go to View > Open View and search for Claude. You can also check if the extension is properly installed and enabled in the Extensions panel.

Context menu options not showing

Ensure the Claude extension is activated by opening the Claude panel at least once. Check that you have code selected before right-clicking. If options still don't appear, try reloading the VS Code window with Ctrl+Shift+P then Developer: Reload Window.
