Background Delegation

What It Is

Background Delegation hands off tasks to a cloud-based Copilot coding agent on GitHub. Your terminal is immediately freed. The agent works on a branch in GitHub, and you review the result there — as a branch diff or as a PR when you ask Copilot to create one.

This is distinct from async PowerShell (for local long-running processes like builds/servers), which still uses mode: "async" in the powershell tool.

When to Use

• Large refactors or multi-file migrations you don't want to block on
• Full test suite additions or comprehensive documentation generation
• Complex tasks where you want research or an implementation plan before any code is written
• Any task that benefits from running in a fresh, isolated context on GitHub
• Handing off work while you continue unrelated local development
