Cortex Code is a coding agent, not a chat with a different icon. You point it at a repository, describe the change, and it works through the task inside an isolated runtime — reading, editing, running your build and tests — while you watch a timeline of what it did and decide how much it may do on its own.

Quickstart

Sign in, connect GitHub, start a Cloud session, review the timeline.

Overview

What Code is, who can open it, and what it deliberately is not.

CLI

The same Code sessions from your terminal, scripts, and CI.

Core guides

Sessions

A session is a timeline of the work — files read, edits, commands, plans — with Stop always one click away.

Ask, Plan, Agent

Choose how much a turn may change. Ask reads, Plan proposes, Agent edits and runs.

Connect GitHub

Reach repositories through Connect GitHub. No pasted tokens; Reconnect when a grant lapses.

Cloud runtimes

One isolated guest per session on the same farm as Bot, prepared by the agent.

​
Desktop and terminal

Code on desktop

This PC and SSH hosts exist on the desktop app and the CLI. The browser stays Cloud-only.

Code in the terminal

How the CLI maps onto Code sessions, and where the full CLI documentation lives.

​
Advanced

  • Cortex Security — GitHub App pull-request review that stays failed when it fails.
  • How Code works — workspace tools execute inside the attached guest; modes withhold mutating tools.
  • Troubleshooting — gates, Reconnect, Cloud availability, and what a failed review means.
