The [plugin skeleton workflow](https://github.com/discourse/discourse-plugin-skeleton/blob/main/.github/workflows/discourse-plugin.yml) uses the following, which I _think_ will test against the default branch, so `main`. The reusable workflow has an optional `core_ref` input and as far as I can tell, without it the `discourse/discourse` repository’s default branch will get checked out.

```plaintext
jobs:
  ci:
    uses: discourse/.github/.github/workflows/discourse-plugin.yml@v1

```

I can’t say whether that actually limits it to testing against `main` or not but if it does, you could add a matrix strategy to run once for each ref you want to test against.

```plaintext
jobs:
  ci:
    strategy:
      matrix:
        target: [tests-passed, stable]
    uses: discourse/.github/.github/workflows/discourse-plugin.yml@v1
    with:
      core_ref: ${{ matrix.target }}

```
