GitHub just turned its agent strategy into an actual product surface. At Microsoft Build, the company unveiled the GitHub Copilot app, a dedicated desktop experience built specifically for running, steering, and shipping work produced by multiple coding agents in parallel. Along with it came a generally available Copilot SDK, sandboxed execution environments, a voice-enabled CLI, and a meaningfully upgraded code review system.

The pitch is straightforward: while the agentic shift has made development faster, it has also led to disjointed workflows, more context switching, and too much time spent reviewing agent-generated code. Most IDEs assume a single human driver. Once you have three or four agents fanning out across a repo, that model breaks down.

A control center for parallel agents

The new app gives you a single My Work view where you can see work in motion across connected repositories: active sessions, issues, pull requests, and background automations. It is in technical preview for existing Copilot Pro, Pro+, Business, and Enterprise customers, with a new Copilot Max tier aimed at people running heavy agent workloads.

The interesting architectural choice is isolation. Every session runs in its own git worktree, a real, isolated copy of your branch. This helps parallel agent sessions work without stepping on each other. Worktrees are managed automatically, so you do not end up with a stack of half-finished branches to clean up after the agents finish.

On the shipping side, GitHub introduced Agent Merge, which monitors CI, tracks required reviewers, addresses failing checks, and waits for all conditions to be satisfied before merging. You decide how aggressive that autopilot gets, from simply fixing red CI to merging when conditions clear.
