Overview

Arco is an open-source plugin that shows your GitHub and Linear issues inside a Codex chat so you can read and change them there. It saves switching to a browser tab when you want an agent to work from an issue. You read issue cards inline, open details in a side panel, pick passages to add as context for your next prompt, and update Markdown, labels and Linear states and priorities. The ready-made build is for Apple silicon Macs, and it connects through the gh CLI and a Linear OAuth app you set up. It can change issues in your GitHub and Linear accounts.
