Engines

Shelzo runs ten coding-agent CLIs. Each CLI keeps its own sign-in, configuration, and subscription; Shelzo does not proxy your engine tokens.

Install and sign in

1. Choose an engine below. These are the same installation instructions shown on Shelzo’s Welcome screen.
2. Run the command in a terminal. Commands beginning with npm need npm available there.
3. Open the installed CLI and follow its sign-in instructions.
4. Return to Settings › Engines and check again. Choose the engine when starting a chat or terminal.

Installation commands

Claude Code, Codex, Cursor Agent, Gemini CLI, Grok Build, OpenCode, Droid, and Copilot support terminal and structured chat. Kimi Code and Muse Code are terminal-only.

Claude Code

          npm i -g @anthropic-ai/claude-code
        

Codex

          npm i -g @openai/codex
        

Cursor Agent

          curl https://cursor.com/install -fsS | bash
        

Gemini CLI

          npm i -g @google/gemini-cli
        

Grok Build

See x.ai for the Grok Build CLI. Shelzo’s Welcome screen does not provide an installation command.

OpenCode

          curl -fsSL https://opencode.ai/install | bash
        

Droid

          curl -fsSL https://app.factory.ai/cli | sh
        

Copilot

          npm i -g @github/copilot
        

Kimi Code

          curl -fsSL https://code.kimi.com/kimi-code/install.sh | bash
        

Muse Code

          curl -fsSL https://dev.meta.ai/install.sh | bash
        

If it fails

First check that the CLI starts from a fresh terminal. Shelzo discovers local engines through your login shell’s PATH. Use Settings › Engines to check sign-in again; an unknown status does not confirm a successful login. Complete sign-in in the CLI, then restart the chat. For SSH workspaces, install and sign in on the remote host: local installations do not count.
