GitHub: plan, build, verify and observe with Copilot agents

GitHub's guide says writing code got faster while the work around it did not. It cites more than 1.2 billion commits in one October week, over 400% more than a year earlier, and a Faros AI study where pull requests spent 441% longer in review as teams moved from low to high AI adoption. The post walks through Plan, Build, Verify and Observe with Copilot: gather context into plans and issues, run tasks in cloud sandboxes with session continuity, use stacked PRs and Copilot review, then investigate production with observability connectors. It stresses that judgment still sits with the developer.
