            description="Retrieve last commit hash.",
        ),
    )

I'm not sure if I'm doing it the way it should be, but is this the right way to get the commit hash? I need to add a

input_digest

and

working_directory

as well, I guess? Am I supposed to create a Snapshot with

.git

? 🤔

Hmm, we should probably make the git state available as a product you can request, since this is likely a common need. And since copying the

.git

directory into a sandbox every time is likely to be inefficient.

I hope this is enough: https://github.com/pantsbuild/pants/issues/13724

For read only purposes, would it make sense to support symlinks in the sandbox? Of course, it would be difficult to guarantee that it's not written to..
