opencode Chat for VS Code

A native VS Code chat panel for the opencode AI coding agent — like GitHub Copilot Chat, but for opencode.

Features

• Sidebar chat panel with streaming responses
• Auto-detects a running opencode server and reconnects when it comes back
• Injects the active file, current selection, and git branch into every prompt
• Keyboard shortcut to send the current selection (Cmd+Shift+O / Ctrl+Shift+O)
• New-session button to start fresh without restarting the server
• Automatic light/dark theming using VS Code CSS variables

Prerequisites

1. Install opencode

   npm i -g opencode-ai@latest

2. Start the opencode server in the project you want to chat about:

   opencode serve

   By default it listens on http://localhost:4096.

Installation

From the VS Code Marketplace

(Coming soon)

From a VSIX

1. Download the latest opencode-chat-*.vsix from Releases.
2. In VS Code, run Extensions: Install from VSIX… and pick the file.

Usage

1. Open a folder (workspace) in VS Code.
2. Open the Explorer sidebar — you'll see a new opencode view.
3. Start typing. Enter sends, Shift+Enter inserts a newline.
4. Select code and press Cmd+Shift+O (Ctrl+Shift+O on Linux/Windows) to send the selection to chat.
5. Click + in the panel header to start a new session.

The status-bar indicator turns green when the extension is connected to a running server.
