GitHub Agentic Workflows is now in public preview, and the most interesting part is not that agents can write workflow logic from Markdown.
The interesting part is where GitHub chose to put them.
Agentic Workflows are defined in natural language Markdown, then compiled into standard GitHub Actions YAML. They run through existing runner groups, organization policies, sandboxes, firewalls, output validation, and threat detection. A day later, GitHub also removed the need for a personal access token, letting these workflows use the built-in GITHUB_TOKEN, bill AI credits to the organization, and cap token usage per workflow run.
That sounds like a set of product details.
It is also a pretty clear architectural statement: the future of agent automation looks less like chat and more like CI/CD with a reasoning step inside it.
