Cursor's @ Commit is amazing, I use it all the time but I've not seen much talk about it.

It adds the current diff to the context. Here's a nice example:

ooh cool. feels a bit like? https://github.com/dagger/dagger/issues/8520

#

i guess the way i'd suggest solving this is by just adding more fields to the git api? and then we can just pass that object in with WithGit

#

not sure what those fields should be. maybe we should have GitRef.parent: GitRef to be able to traverse history.
we could also have GitRef.Diff: String to get the text diff of the given ref

#

i think that gives us the ability to do some more complex git stuffs

working on some of this now, since it's a pretty easy addition, and i'm in the area

#

will open something we can bikeshed around

There's also the relationship to the module system, eg. "run the tests on the current commit with and without staged changes"

😄 lol great minds

#

i'm thinking we add a GitRepo.Working that gives you the potentially dirty state of the git repo

#

i can add contextual git as well i think 🤔 will need to think through how, but can hack something together separately

#

i wanna get something for this soonish, since i want to write a code review agent for kubecon

for this i think contextual git is the call. i'm thinking we add a magic pragma, something like // +defaultGit will fill the arg with the current git state for that module

#

dunno, maybe there's something else we can do, but this feels "kinda right", and also very very easy to bolt in
