name: Upload to Hackage

Here's a simple example of how you might create a GitHub Actions workflow to upload a Haskell package to Hackage:

on: push: branches: - main

I'm assuming you're looking for a piece of code related to Hackage (not "hacoo") and GitHub. Hackage is a package repository for the Haskell programming language.
