On 28 October 2026 GitHub published its VS Code release notes for Universe. The headline is the Agent Host: AI coding sessions are now separate from any single editor window, so an agent keeps working after a developer closes a project.
What GitHub says is available
- Cloud sessions across clients. A session started in VS Code runs on GitHub’s infrastructure and can be continued in VS Code, the GitHub Copilot app, GitHub Mobile, github.com or Copilot CLI. Sessions begun from Slack or Microsoft Teams messages can be continued too.
- Mobile control. Developers can check on, direct or start tasks on their own machine from GitHub Mobile.
- Remote machines. Agents can run on a remote machine over SSH, though that machine must stay running.
- Preview and experimental features. Side-by-side model comparison with a “Judge” model is in preview. Computer use, where Copilot operates desktop apps with per-app approval, is experimental. Connectors to services such as Slack and Notion are in preview, and administrators can restrict plugins and marketplaces by policy.
GitHub does not label every item generally available, so treat anything not marked as preview or experimental as available now but check it before relying on it.
What it means
The picture of a developer typing alongside an AI assistant is giving way to something closer to delegation: set a task, walk away, review the result. That can shorten delivery, but it moves the risk from writing code to reviewing it. Work that happens unattended needs clear limits on what the agent may touch.
So what
Ask your development partner who reviews agent-produced changes, what the agent is allowed to access, and whether unattended sessions are covered by your security policy. Our AI-assisted development service builds that review step in from day one. To talk it through, start a project.
