This handles the boring but necessary setup work before you can actually use Cyrus: checking for Node.js 18+, jq, and GitHub CLI, then installing the cyrus-ai package globally. It'll detect your OS and offer the right install commands if anything's missing. There's also an optional check for agent-browser, which automates app setup for Linear, GitHub, and Slack integrations, though you can skip it and do manual setup instead. One nice touch is it respects your package manager preference (npm, pnpm, bun, or yarn) and remembers it for later. The skill is also careful about the ~/.cyrus/.env file, never reading secrets into context, which is the right call for credential handling.
