I think we want that exactly one of the two checkboxes is ticked.
I could not find documentation for this but this does not seem to be possible with "type: checkbox" but would require to use "type: dropdown".
Alternatively we could use a GitHub action to enforce this requirement.

Okay, I've checked both options in the issue template UI, it looks like this:

Dropdown

Checkbox

After looking at the issue template UI, I'm not sure a dropdown is the best choice here.

Or maybe shortening the AI acknowledgment section description could be another option if we want to use the dropdown menu.

Other feedback is welcome.

I feel that using a dropdown works well here. It allows us to require a selection and ensures that exactly one option is chosen, which isn’t something we can reliably enforce with checkboxes.

we can keep short labels for the dropdown and put a detailed explanation in the field description.

- type: dropdown
  attributes:
    label: AI acknowledgment
    description: >
      Select an option. If AI was used, ensure you reviewed all AI-generated content.
    options:
      - No AI
      - AI used
  validations:
    required: true

+1 to use dropdown here.

Okay great! Just to double-check:

• For the issue templates: use a "No AI" / "AI used" dropdown menu.

• For the PR template: use the existing checkbox style I suggested.

Is that the direction we want to go?

I should've been more clear: the requirement that only one option is selected can be solved with a dropdown but personally I think checkboxes with a Github Action checking that one option is selected would be better as a dropdown with only two options feels weird.

Could @eslint/eslint-tsc chime in to provide clear direction on how we should proceed?

There are several opinions but no definitive consensus, so I'm unsure which direction to take.

Let's use the checkboxes.

My reason: Dropdowns always have a default value selected so it can be easy to overlook and skip. The checkboxes are a lot more obvious.
