Muse Code for VS Code (Unofficial)

A native VS Code chat UI for Muse Code, Meta's agentic terminal coding agent.

Unofficial community project. This extension is not made, endorsed, or supported by Meta. "Muse" and "Muse Code" are Meta's names for their product; they are used here only to describe what the extension connects to.

Inspired by the Claude Code VS Code extension. The layout, commands, keybindings, settings and workflow of this extension deliberately mirror Anthropic's Claude Code for VS Code so that anyone who knows that extension feels at home. This project is not affiliated with Anthropic or Meta.

• Works alongside you: Muse explores your codebase, reads and writes code, and runs terminal commands with your approval.
• Integrated with the editor: Muse knows about your current file and text selection, and you can review its file changes as a diff right in the editor.
• Durable sessions: resume any past conversation for the workspace, including ones started from the muse terminal TUI.
• Agentic features supported: approvals with policy amendments, user-input questions, subagents, todo lists, context compaction, model and reasoning-effort selection, and user shell commands.

Requirements

• VS Code 1.98.0 or higher.
• The muse CLI, version 1.0.3 or later. Run muse login once before using the extension. The extension looks for muse on PATH, in common install locations (~/.local/bin, /opt/homebrew/bin, ...), and via your login shell, so it works even when VS Code is launched from the Dock. Set museCode.executablePath only if it still cannot be found.

Getting started

1. Open a folder.
2. Click the Muse icon in the editor title bar, or press Cmd+Escape (Ctrl+Escape on Windows/Linux).
3. Type a message and press Enter.

Use @ to mention files, / for commands, and ! to run a shell command yourself.
