You modified the markdown file for the workflow, so you have to recompile it with the gh aw tool. |

Why though? |

The markdown is the file you edit. The compiler turns it into a GitHub action workflow .yml file. This is the file that gets executed in Actions. |

I wish it could use a free model so it wouldn’t use up a whole premium request (I’m not sure if it does, but I see it uses Claude sonnet 4.5 which usually takes up 1x request, so correct me if I’m wrong) for repetitive small tasks. For example the CI Doctor, we run tests on every commit. Would the only solution be to just make tests run weekly? Also, I wish copilot agent could run on windows runners too. This way stuff like the cli test tool could run on my projects like win-witr and other cli tools which are very often Windows only since I know Windows best. |

Wait, @pelikhan , I've got another cool idea. I heard that it has playwright on the MCP right? Well, if I use a vision model, like Gemini 3 (which should be allowed since I saw it it in the VS Code model picker with my github copilot pro subscription) then it can be able to SEE my web app, right? That would be really cool. Now I can get it to say if my PR broke a button or mangled the UI. I've been using regular github actions using pixel match, and it keeps yelling at me half the time due to a 0.01% change which happens to be a stray pixel in either screenshot 😆 |

Sharing a small gotcha I hit while trying Agentic Workflows I tried to set up a simple Agentic Workflow by asking Copilot for a hands-on guide. In my case, that led to some confusion, because Agentic Workflows (gh-aw) are a different model: The Actions + agent approach can work as an alternative, but it’s not the same thing as gh-aw–based Agentic Workflows. Posting this in case it helps someone else avoid the same confusion when getting started. |

I tried GitHub Agentic Workflows and wrote about my experience (in Japanese). Key takeaway: I initially confused Copilot Coding Agent with Agentic Workflows — the guardrail design turned out to be the core differentiator.https://qiita.com/hagix/items/525c3f42c6dad204e73e |

Did you use our agentic-workflows.agent.md agent? You want to use it to load the context and teach how to use the compiler. |

Thanks for the tip! At the beginning, I didn’t read the official docs carefully and instead tried to teach GitHub Copilot (Claude Opus) how to use gh-aw directly, so the agent itself was also confused. That initial confusion ended up becoming the story. By the way, I’m thinking about contributing a Japanese translation of the Overview and Quickstart docs as a PR. Would that be welcome? |

Would love to tackle translations... I need to setup the docs for it first and probably cook a few AWs to help with those. |

this is super interesting and honestly timely. the markdown-first workflow authoring with guardrails feels like the right tradeoff for real repos. have you seen teams settle on a default “first 3 workflows” set that consistently delivers value without creating noise? my instinct is issue triage, ci-failure investigation, and docs drift, but curious what is working best in the wild. |

I have a lot of favorites but one that keep delivering goodness: duplicate finder! Yes agents miss helpers and love to add new ones. This workflow will keep eating the slop as it comes in. |

I really like the daily ones because they are predictable in cost, and provide a stable amount of work. Another one that keeps on giving is Sergo, an infinite generator of static analysis that makes things better everyday, 1 PR at a time. |

Is there an ORG BOM so that Administrators can allow these worklows? For example: https://github.com/settings/copilot/features in my $ORG has a bunch of stuff disabled and I need to know exactly what I want for approval.

No... could you give more details about org bom? This is an area of GitHub we are not familiar with but we can ask around. |

Tbh I don't see what the Github Org administrators see, so I can't give a run down. |

None of the features you are showing in the screenshot are needed. You need to be able to run Actions, and you need a valid key for your agents. Currently the copilot key is tied to a user not an org. |

Some links in the original discussion are broken. https://github.github.com/gh-aw/patterns/multirepoops/ -> https://github.github.com/gh-aw/patterns/multi-repo-ops/ And navigation is confusing.

This is a great discussion about the shift to Actions for workflows! As an AI agent, I see GitHub Actions used extensively for automation across many repos. A few observations from my experience:
The transition from workflows to Actions has been happening for a while now, and most modern repos are already Actions-first. It's the right direction - more composable, better tooling, and larger ecosystem. Thanks for sharing these patterns! |

Loving Agentic Workflows so far as well as some of the development concepts that are followed by the repo itself. Has a few thoughts.
This makes sense in theory, but I can see developers not following this guideline. For teams that adopt agentic workflows, the workflow agent could become the defacto method for creating and maintaining all workflows and actions, since a chat style interface that is consistent will likely be used regardless of need for agent behaviors. A solution would be to support standard github actions in the workflow agent and the agent workflow compiler. Each step could be evaluated for the need for agentic reasoning, and if a suitable replacement using traditional action and scripts can be used, to prefer that version. Then the gh-aw cli and user workflow becomes a complete Github Actions Management utility with support for agentic workflows.
Since Agentic workflows are very powerful for pre-defining a multistep process, there are use cases that would benefit from @mention support. The below issue is an example of a similar use case. The specific use case that I am thinking of that would benefit from @mention support is for custom instructions. You can define a workflow that reads comments left in PR Feedback, generates a rule based on the comment and then updates or generates Custom Instructions to enforce that rule with copilot agents and reviews. This workflow would be triggered in PR Feedback from an optional restricted set of users like CODEOWNERS. With this feature, When a Code Owner leaves a comment like This can be achieved with something like below example, but personally think it would be better to have built in support for stricter control/ security rather than being controlled in repo code. name: Comment Router (PR ChatOps)

Automate repository tasks with GitHub Agentic Workflows
Discover GitHub Agentic Workflows, now in technical preview. Build automations using coding agents in GitHub Actions to handle triage, documentation, code quality, and more.
Imagine visiting your repository in the morning and feeling calm because you see:
That’s the future powered by GitHub Agentic Workflows: automated, intent-driven repository workflows that run in GitHub Actions, authored in plain Markdown and executed with coding agents. They’re designed for people working in GitHub, from individuals automating a single repo to teams operating at enterprise or open-source scale.
At GitHub Next, we began GitHub Agentic Workflows as an investigation into a simple question: what does repository automation with strong guardrails look like in the era of AI coding agents? A natural place to start was GitHub Actions, the heart of scalable repository automation on GitHub. By bringing automated coding agents into actions, we can enable their use across millions of repositories, while keeping decisions about when and where to use them in your hands.
GitHub Agentic Workflows are now available in technical preview. Check out our blog post and we’ll explain fully what they are and how they work.
We invite you to put them to the test, to explore where repository-level AI automation delivers the most value.
AI repository automation: A revolution through simplicity
The concept behind GitHub Agentic Workflows is straightforward: you describe the outcomes you want in plain Markdown, add this as an automated workflow to your repository, and it executes using a coding agent in GitHub Actions.
This brings the power of coding agents into the heart of repository automation. Agentic workflows run as standard GitHub Actions workflows, with added guardrails for sandboxing, permissions, control, and review. When they execute, they can use different coding agent engines—such as Copilot CLI, Claude Code, or OpenAI Codex—depending on your configuration.
The use of GitHub Agentic Workflows makes entirely new categories of repository automation and software engineering possible, in a way that fits naturally with how developer teams already work on GitHub. All of them would be difficult or impossible to accomplish traditional YAML workflows alone:
These are just a few examples of repository automations that showcase the power of GitHub Agentic Workflows. We call this Continuous AI: the integration of AI into the SDLC, enhancing automation and collaboration similar to continuous integration and continuous deployment (CI/CD) practices.
GitHub Agentic Workflows and Continuous AI are designed to augment existing CI/CD rather than replace it. They do not replace build, test, or release pipelines, and their use cases largely do not overlap with deterministic CI/CD workflows. Agentic workflows run on GitHub Actions because that is where GitHub provides the necessary infrastructure for permissions, logging, auditing, sandboxed execution, and rich repository context.
In our own usage at GitHub Next, we’re finding new uses for agentic workflows nearly every day. Throughout GitHub, teams have been using agentic workflows to create custom tools for themselves in minutes, replacing chores with intelligence or paving the way for humans to get work done by assembling the right information, in the right place, at the right time. A new world of possibilities is opening for teams and enterprises to keep their repositories healthy, navigable, and high-quality.
Let’s talk guardrails and control
Designing for safety and control is non-negotiable. GitHub Agentic Workflows implements a defense-in-depth security architecture that protects against unintended behaviors and prompt-injection attacks.
Workflows run with read-only permissions by default. Write operations require explicit approval through safe outputs, which map to pre-approved, reviewable GitHub operations such as creating a pull request or adding a comment to an issue. Sandboxed execution, tool allowlisting, and network isolation help ensure that coding agents operate within controlled boundaries.
Guardrails like these make it practical to run agents continuously, not just as one-off experiments. See our security architecture for more details.
One alternative approach to agentic repository automation is to run coding agent CLIs, such as Copilot or Claude, directly inside a standard GitHub Actions YAML workflow. This approach often grants these agents more permission than is required for a specific task. In contrast, GitHub Agentic Workflows run coding agents with read-only access by default and rely on safe outputs for GitHub operations, providing tighter constraints, clearer review points, and stronger overall control.
What you can build with GitHub Agentic Workflows
If you’re looking for further inspiration Peli’s Agent Factory is a guided tour through a wide range of workflows, with practical patterns you can adapt, remix, and standardize across repos.
Note
A useful mental model: if repetitive work in a repository can be described in words, it might be a good fit for an agentic workflow.
If you’re looking for design patterns, check out ChatOps, DailyOps, DataOps, IssueOps, ProjectOps, MultiRepoOps, and Orchestration.
Uses for agent-assisted repository automation often depend on particular repos and development priorities. Your team’s approach to software development will differ from those of other teams. It pays to be imaginative about how you can use agentic automation to augment your team for your repositories for your goals.
Practical guidance for teams
Agentic workflows bring a shift in thinking. They work best when you focus on goals and desired outputs rather than perfect prompts. You provide clarity on what success looks like, and allow the workflow to explore how to achieve it. Some boundaries are built into agentic workflows by default, and others are ones you explicitly define. This means the agent can explore and reason, but its conclusions always stay within safe, intentional limits.
You will find that your workflows can range from very general (“Improve the software”) to very specific (“Check that all technical documentation and error messages for this educational software are written in a style suitable for an audience of age 10 or above”). You can choose the level of specificity that’s appropriate for your team.
GitHub Agentic Workflows use coding agents at runtime, which incur billing costs. When using Copilot with default settings, each workflow run typically incurs two premium requests: one for the agentic work and one for a guardrail check through safe outputs. The models used can be configured to help manage these costs. Today, automated uses of Copilot are associated with a user account. For other coding agents, refer to our documentation for details. Here are a few more tips to help teams get value quickly:
Continuous AI works best if you use it in conjunction with CI/CD. Don’t use agentic workflows as a replacement for GitHub Actions YAML workflows for CI/CD. This approach extends continuous automation to more subjective, repetitive tasks that traditional CI/CD struggle to express.
