Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipes/supervisor-pydantic/recipe.yaml) and found it was in an excellent condition.

I do have some suggestions for making it better though...

For recipes/supervisor-pydantic/recipe.yaml:

• ℹ️ The recipe is not parsable by parser conda-recipe-manager. The recipe can only be automatically migrated to the new v1 format if it is parseable by conda-recipe-manager.

@conda-forge/help-python all set! windows is failing but recipe is no arch, looks like an upstream issue that will be fixed.
