GitHub Launches Agentic Workflows — "Continuous AI" Enters the CI/CD Pipeline

GitHub released a technical preview of Agentic Workflows, the most significant developer infrastructure shift since Copilot launched. AI agents (Copilot, Claude Code, or OpenAI Codex) now run as first-class participants inside GitHub Actions. Workflows are defined in natural-language markdown, compiled to Actions YAML via the gh aw CLI. The security architecture is defense-in-depth: read-only repo access by default, sandboxed execution, network isolation, SHA-pinned dependencies, and a SafeOutputs subsystem that gates all write operations through deterministic filters. PRs never auto-merge. What to do: Install gh extension install github/gh-aw and start with Issue Triage — the lowest-risk entry point. This is the beginning of agents as a native CI/CD primitive.
