How do I setup an environment for openhands resolver?

[zachmayer]

What problem or use case are you trying to solve?
I'm trying to use openhands with R. Claude can program in R just fine, but it burns a boatload of tokens trying to install the R packages needed for my repo. I already know how to do this, so I want to setup an R environment manually and install all the needed packages before running openhands.

However, the openhands resolver seems to be a reusable workflow, so I can't add steps before it to setup the environment it runs in.

Describe the UX of the solution you'd like
Some way to run some steps before the openhands resolver, in order to configure the environment for maximum success.

Do you have thoughts on the technical implementation?
no, github actions confuses the hell out of me

Describe alternatives you've considered
yelling at my laptop

Additional context
I tried adding some steps but got reusable workflows should be referenced at the top-level `jobs.*.uses' key, not within steps

Hmmm @malhotra5 is there a way to achieve this with the current functionality?

@zachmayer makes a good point! We can't support package installations directly from the Github workflow, as it needs to exist in the runtime container.

We have the following solution for this, but requires some work from the user:

1. Setup a custom sandbox, which will contain the appropriate packages.
2. Pass sandbox_base_container_image="custom-image" parameter through the Github workflow, which will load in the custom sandbox.
