According to Satya Nadella on X, GitHub Copilot CLI now includes a multi-model reflection loop that acts as a reviewer to catch issues early before they compound. According to Microsoft’s GitHub Copilot documentation, reflection workflows use multiple models to iteratively critique and refine outputs, improving code suggestions and remediation steps in terminals. As reported by GitHub, this enables earlier defect detection, security linting, and command validation within developer workflows, reducing rework and speeding incident response in CI and DevOps pipelines.
