 The [Repo Assist workflow](../workflows/repo-assist.md?plain=1) is a [GitHub Agentic Workflow](https://github.blog/ai-and-ml/automate-repository-tasks-with-github-agentic-workflows/) for a friendly repository assistant that runs regularly to support contributors and maintainers. It can also be triggered on-demand via `/repo-assist <instructions>` to perform specific tasks.

It maintains a monthly activity summary for maintainer visibility.
