Exploring the agent-first GitHub Copilot desktop app | GitHub Checkout
GitHub is pitching Copilot Desktop as an agent-first layer over coding workflows: less terminal glue, more parallel execution with guardrails. The sharp bit is using git working trees to isolate multiple agents, plus merge, automation, and MCP hooks in one UI. Developers should care because it turns multi-agent coding from a fragile demo into something teams can run without constant branch collisions.
