GitHub Agentic Workflows bring Markdown-defined agents to GitHub Actions for hands-off repo maintenance

GitHub Agentic Workflows (technical preview) let teams describe maintenance outcomes in Markdown and run them safely inside GitHub Actions with permission guardrails. They support multiple agent engines to automate triage and documentation upkeep across repositories.

GitHub Agentic Workflows, in technical preview, run Markdown-defined automation inside GitHub Actions and support Copilot CLI, Claude Code, and OpenAI Codex for repository maintenance.

  • Define the desired outcome in plain Markdown files, then execute the workflow through GitHub Actions.
  • Use built-in sandboxing and permission-based guardrails to control what automated steps can do.
  • Automate issue triage tasks such as summarizing, labeling, and routing new issues.
  • Keep documentation from drifting by automatically aligning README content with recent code changes.
  • Apply the approach at scale: Carvana uses it for multi-repository engineering tasks, while Home Assistant uses it to surface trending themes from thousands of open issues.
