Graphene is a tool I ve been working on with Codex to create, publish, manage stacked branches and PRs. It s become a indispensable tool to manage code for me and other co-workers since moving off of paid stacked PR products.It stores its state in local gitconfig and is just a wrapper around regular git commands. Graphene doesn t actually interact with the Github API at all. PRs have to be created manually (but it does print quick links after a push to create properly stacked PRs)Graphene comes with agent skills so you can have your favourite agent create atomic PRs that are easy for humans to review.I m curious to see if anyone has any feedback on it.
