oas.yml

# Run quality control on the (generated) Open API specification.
#
# The OAS must:
# * not be outdated w/r to the code from which it is generated
# * not have any linting errors
# * be valid input to generate a Postman collection
# * be valid input to generate SDKs in commonly used languages/frameworks
#
# When dealing with multiple versions, you can adapt this workflow to run a matrix and
# pass arguments down that way, and/or use a parent workflow to call this workflow for
# each matrix item. See https://docs.github.com/en/actions/sharing-automations/reusing-workflows
