# GitHub Agentic Workflows

17 Hacker News commenters recommended GitHub Agentic Workflows and 25 criticized it, November 2025 to November 2026. It was recommended in 6 of 13 months.

**Verdict:** People like the idea of markdown-defined agents handling event-driven chores like triage, docs sync and CI fixes. Critics warn about security, especially running on public repos, and the overhead of AI in workflows.

## Why people recommend it

- Compelling markdown-defined agent concept (3 comments): "Similar idea (rooted on "agents as markdown") but on the outer loop is taking shape at GitHub with GitHub Agentic Workflows." ([source](https://news.ycombinator.com/item?id=47392741)) "mostly because I believe it is a great idea, and I am experimenting on it myself" ([source](https://news.ycombinator.com/item?id=46937052)) "We find that there's something very compelling about the shape of this" ([source](https://news.ycombinator.com/item?id=46937635))
- Delegates routine chores to agents (2 comments): "it looks solid for the event-driven automation shape (triage, docs sync, CI fix)" ([source](https://news.ycombinator.com/item?id=47727351)) "The value is "delegate chores that cannot be handled by a heuristic"." ([source](https://news.ycombinator.com/item?id=46938024))
- Saves time on reviews and research (2 comments): "create a simple but effective usage for my day 2 day reviews" ([source](https://news.ycombinator.com/item?id=47093650)) "this feature alone has saved me days of work/research" ([source](https://news.ycombinator.com/item?id=46133517))
- Solid security controls out of the box (2 comments): "This is a solid step forward on execution safety for agentic workflows." ([source](https://news.ycombinator.com/item?id=46936740)) "come with many additional security controls out of the box" ([source](https://news.ycombinator.com/item?id=47768583))

## What people warn about

- Security model and public repo risks (5 comments): "they still have some work to do, either on the security model" ([source](https://news.ycombinator.com/item?id=48834492)) "It seems like the proper fix is for GitHub not to allow their agentic workflow to execute in a public repo context" ([source](https://news.ycombinator.com/item?id=48829768)) "I'm certainly not going to trust them with access to information and then allow anyone to send them prompts." ([source](https://news.ycombinator.com/item?id=48828380))
- Hallucinated or incorrect fixes (3 comments): "The copilot agent then implemented that by adding a replace statement, which is not how you are supposed to do this." ([source](https://news.ycombinator.com/item?id=46944008)) "hallucinations that then churn through I don't know how many tokens trying to "fix it"" ([source](https://news.ycombinator.com/item?id=46936462)) "I feel like this solution hallucinated the concept of Workflow Lock File" ([source](https://news.ycombinator.com/item?id=46935095))
- Billing errors despite paying (3 comments): "I paid or tried to for the extra billing, I followed all the instructions and still got the same error." ([source](https://news.ycombinator.com/item?id=46940682)) "we pay them for the actions and everything and still ran into this issue" ([source](https://news.ycombinator.com/item?id=46936934)) "even when I tried to pay, it was still failing under the same error" ([source](https://news.ycombinator.com/item?id=46940712))
- Overhead and unnecessary AI use (3 comments): "always running your action from a Markdown file seems extremely wasteful in terms of resources" ([source](https://news.ycombinator.com/item?id=46191722)) "That is literally just creating overhead for me and it sounds like an excuse to shoehorn AI in to a workflow more than anything else." ([source](https://news.ycombinator.com/item?id=46938067)) "I find this confusing: I can see the value in having an LLM assist you in developing a CI/CD workflow" ([source](https://news.ycombinator.com/item?id=46935569))
