Rayucode

Rayucode brings the full power of the Rayu AI coding agent into Visual Studio Code.

Powered by the same engine, tool platform, and slash commands as the Rayu CLI, Rayucode runs as a dedicated assistant in your sidebar, allowing you to build, debug, and review code changes seamlessly inside your editor.

Features

• Multi-Provider AI: Use Claude (Anthropic), OpenAI, DeepSeek, Google Gemini, AWS Bedrock, or custom OpenAI-compatible models.
• Interactive Review Card: Review files changed by Rayu turn-by-turn with side-by-side git diffs, and keep or undo changes individually or in bulk.
• Slash Commands & Palettes: Type / to trigger the slash command palette (/help, /compact, /cost, /model, /clear, /review), and @ to mention workspace files.
• Permission Modes: Control execution safety by cycling modes in the composer (Ask, Auto-edit, Plan, Full Manage, Orchestrator).
• Context Usage: Live context window tracking in the panel header.
• MCP Server Integration: Manage and reconnect Model Context Protocol servers directly from the extension.
• Single Credential: Shares configuration and credentials with the Rayu CLI (~/.rayu/).

Getting Started

1. Install the Rayucode extension in VS Code.
2. Open the Rayucode icon in the Activity Bar.
3. Sign in to Rayu or connect with an API key (/connect in the terminal).
4. Start chatting and coding!

How it runs

Rayucode ships the same engine the terminal CLI runs, in one of two forms:

• Platform packages (rayucode-<version>-<platform>.vsix) carry a compiled executable at bin/rayucode-engine (.exe on Windows), plus a bundled rg. This is the recommended install: it starts instantly and needs no Node.js.
• The universal package (rayucode-<version>.vsix) runs engine.mjs with the Node.js that ships inside VS Code. Use it only when no build exists for your platform.

To install a platform package by hand, download the matching .vsix and run code --install-extension rayucode-<version>-<platform>.vsix (or use Extensions → … → Install from VSIX…).

Search uses the bundled rg (bin/rg), so it does not depend on your PATH.

Memory: each conversation runs as its own engine process with a limit based on this machine's RAM. If an engine reaches the limit it is stopped and replaced; the next message continues the same conversation instead of losing it. Change the limit with rayucode.engine.maxMemoryMB, or point at a different binary with rayucode.engine.path. Both are machine-scoped, so a workspace cannot redirect them.

Settings

The gear in the sidebar title bar (or Rayucode: Open Settings in the Command Palette) opens the Settings tab, with four sections:

• General — settings shared with the Rayu CLI carry that badge and are saved to the files the terminal reads, through the engine, so both see the same value. Two rows are Rayucode-only and live in Rayucode's own profile: permission mode (which the chat also remembers) and prompt suggestions (off means no extra model request after a turn).
• Account — your profile, plan, credits, usage limits, this month's feature usage and your devices. Signing out here clears the same caches as /logout in the terminal; it keeps a configured API key.
• Integrations — connect Telegram (the shared Rayu bot by QR, or your own bot token), turn on Studio Remote to drive this window from studio.rayucode.com/remote (or pair it with a QR), and install Rayu's GitHub Actions workflows in the current repository.
• About — which engine, ripgrep and memory limit this window is using.

The command is also in the Accounts menu, and a signed-in account shows a credits item in the status bar; click it to open Settings → Account.

Remote-SSH Limitation

Account sign-in via OAuth loopback requires an interactive local browser and is not currently supported in Remote-SSH sessions. For Remote-SSH workspaces, configure an API key via /connect in your remote terminal: Rayucode detects and loads shared credentials automatically.
