I've built a stacked-PR tool for myself, it's just a simple wrapper around git commands. State stored locally in .git/config - https://github.com/alexghr/graphene

Lots of small dashboards/log investigations deployed to private Github Pages for $WORK. This has been a great way to share insights.

I'm currently working on a tool to control my tmux sessions from my phone. Specifically all the codex panes so I can remote control my running sessions from my phone while I'm away from my desk while also keeping them in sync with tmux for when I'm back at my computer. On this one I'm using Codex as a helper, it's not allowed to write any code so it's going along a lot slower :)
