Automate repository tasks with GitHub Agentic Workflows

GitHub Agentic Workflows, currently in technical preview, offer a new approach to repository automation by integrating AI coding agents into GitHub Actions. These workflows are authored in plain Markdown, allowing developers to specify desired outcomes which are then executed by coding agents such as Copilot CLI, Claude Code, or OpenAI Codex. Unlike traditional YAML workflows, Agentic Workflows introduce new possibilities for continuous automation tasks like issue triage, documentation alignment, code simplification, and test improvement, all within a framework that emphasizes safety and control through sandboxing, permissions, and reviewable outputs. The initiative is a collaborative effort by GitHub, Microsoft Research, and Azure Core Upstream, aiming to augment existing CI/CD practices without replacing them, while providing a scalable, secure, and imaginative approach to repository management and software development.
