Research note compiled 2026-06-16. Purpose: evaluate whether GitHub Copilot CLI can replace Claude Code for 24/7 autonomous / agentic engineering on a second machine. Every claim below was checked against official GitHub docs, the GitHub changelog, or the
github/copilot-clirepo. Claims I could not verify are explicitly flagged.
Copilot CLI has genuinely closed most of the gap with Claude Code on agentic workflows, and in one area (cloud delegation) it does something Claude Code's local /loop cannot: it offloads work to GitHub's servers so your laptop can sleep. The mental model is:
- Local autonomous loop →
--autopilot(+--max-autopilot-continues) and--yolo - Local scheduling →
