Evaluating performance and efficiency of the GitHub Copilot agentic harness across models and tasks

GitHub Copilot's agentic harness is a single cross-experience SDK component that orchestrates tools, context, and workflow across CLI, app, and code review. The team claims it delivers task-resolution parity with model-vendor harnesses while cutting token usage across several configurations, backed by public and internal benchmarks and real-world metrics. We debate technical validity, practical stakes for teams, and whether the harness should get most of the credit.
