Cyrus Setup Prerequisites

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.

Install

$ npx -y skills add ceedaragents/cyrus --skill cyrus-setup-prerequisites --agent claude-code

Installs into .claude/skills of the current project.

Files

CRITICAL: Never use Read, Edit, or Write tools on ~/.cyrus/.env or any file inside ~/.cyrus/. Use only Bash commands (grep, printf >>, etc.) to interact with env files — secrets must never be read into the conversation context.

Setup Prerequisites

Checks system prerequisites and installs cyrus-ai.

Step 1: Detect Package Manager

If the user hasn't already specified their preferred package manager, ask:

Which package manager do you prefer? npm, pnpm, bun, or yarn?

Store the answer for use in this and subsequent skills.

Step 2: Check System Dependencies

Run the following checks and report results:

# Node.js >= 18
node --version

# jq (required for Claude Code parsing)
jq --version

# GitHub CLI (required for GitHub integration)
gh --version

For each missing dependency, provide the install command:
