Adoption and Impact of Command-Line AI Coding Agents: A Study of Microsoft's Early 2026 Rollout of Claude Code and GitHub Copilot CLI
Summary
arXiv paper examines the adoption and organizational impact of command-line AI coding agents (Claude Code and GitHub Copilot CLI) during Microsoft's early-2026 rollout. It finds that first-use spread is social-network-driven, retention correlates with coding activity, and adopters executed about 24% more merged pull requests, with effects persisting over four months. The work discusses rollout cost considerations and the limitations of using PRs as a proxy for output.
