Question

In action.yml, an input 'region' is marked 'required: true' and also has 'default: us-east-1'. What should authors understand?

Accepted Answer

Providing both is contradictory practice; required inputs should not rely on defaults as a substitute for clear contracts—callers must still pass required inputs when no default applies as designed — Design clear input contracts: required means callers must supply the input; defaults suit optional inputs. Do not treat defaults as a loophole for confusing required flags.
