Your Claude Code powered Linear agent. Cyrus monitors Linear issues assigned to it, creates isolated Git worktrees for each issue, runs Claude Code sessions to process them, and streams detailed agent activity updates back to Linear, along with rich interactions like dropdown selects and approvals.

Note: Cyrus requires you to bring your own Claude Code keys/billing.

Configure Cyrus through the dashboard at app.atcyrus.com.

# Install Cyrus
npm install -g cyrus-ai

# Authenticate with your token (provided during onboarding)
cyrus auth <your-token>

For Cyrus to create pull requests, configure Git and GitHub CLI. See Git & GitHub Setup.

Keep Cyrus running as a persistent process:

• tmux: tmux new -s cyrus then run cyrus (Ctrl+B, D to detach)
• pm2: pm2 start cyrus --name cyrus
• systemd: See Running as a Service

No installation required. Everything is managed through app.atcyrus.com.

Zero cost option. This requires hosting everything yourself, including your own Linear OAuth app.
