Cursor rules for Elixir and Phoenix app development

We’ve been experimenting with vibe-coding using Cursor and Claude for a while now, and noticed some of its shortcomings. Sometimes we’ve had to make some instructions explicit, so we’ve codified these into Cursor rules that we can use in all our projects.

Now you can do the same:

# Inside your project root
git submodule add \
  https://github.com/optimumBA/cursor_rules \
  .cursor/rules

That’s it. Cursor will automatically use these rules.

When you need to update your git submodule(s), run:

git submodule foreach \
  git pull
