Hi, I've used your original GitHubActions module from https://github.com/ebekker/pwsh-github-action-base some time ago to make my own pwsh-script Action: https://github.com/Amadevus/pwsh-script

I've fixed up some things in the https://github.com/Amadevus/pwsh-script/blob/master/lib/GitHubActionsCore/GitHubActionsCore.psm1 main module file, for example escaping (% should be escaped, for example). I've also added CmdletBinding, and made Set-ActionOutput accept any object which if not a string, will be converted to json. Possibly other changes I don't remember off the top of my head.

I've also written an extensive test suite in Pester - haven't looked at yours, but maybe you can use some from mine.

I can answer any questions or help if you want.

Within an Action, you can get the "Context" via actions/toolkit:
https://github.com/actions/toolkit/blob/master/packages/github/src/context.ts

All it does is grabs env vars and wrap them into an easy to use object...

I wrote something like this here:
https://github.com/TylerLeonhardt/first-interaction-pwsh/blob/355abaae448493cb3e66ad2bbf4535bfd0b037a9/github.psm1#L18-L32

Having support for this in pwsh-github-action-tools would be great!

That is, the ability to use the cache and tool-cache from PowerShell...

I have been playing with some actions in PoshCode/Actions and ended up writing about half of it in node js because I want to cache the install of modules...
