What is GitHub Copilot's Agentic OS?

It's the .github folder evolved into 4 layers—Passive Memory, Progressive Loading, Deterministic Controls, Plugins—for governed AI workflows.

How do I set up GitHub Copilot 4 layers?

Start with .github/copilot-instructions.md for Layer 1, add slash prompts for Layer 2, hooks in Actions for Layer 3, bundle as plugins for Layer 4.

Yes, but shines at scale—cuts context drudgery even for 5-person squads.
