HolyCrab CLI quick start
Choose one installation method: copy a prompt into Codex or Claude Code, or run the command yourself. Then configure your API Key and return to your Agent.
Before you start
- A Windows, macOS, or Linux computer on which you can install Python 3.10 or newer.
- A HolyCrab account and Codex on the same computer. Claude Code is supported in the same way.
One-click install
Open Install HolyCrab CLI, select One-click install, and click Copy prompt. Paste it into Codex or Claude Code on the computer where you want to install the CLI.
- The Agent checks the operating system, dependencies and existing installation, runs the matching installer if needed, and checks the CLI and Agent integration. Follow any dependency, permission or restart instructions it reports.
- When prompted for API Key setup, run
holycrab setupin your own terminal. Paste the API Key only into its protected input, never into Agent chat.
