GitHub Copilot Coding Agent

AI Coding Agentsubscription

GitHub's async, issue-to-PR coding agent -- successor to the 2024 Copilot Workspace technical preview (sunset May 2025). Part of Agent HQ, GitHub's multi-agent "mission control" (public preview since Feb 2026) that lets a single issue be assigned to Copilot's agent alongside third-party agents (Claude, Codex, Gemini, Grok) for side-by-side comparison. Recent additions: local sandboxing for agent file/network/credential access, multi-root workspace sessions, and Agent Merge for auto-resolving review feedback and conflicts.
