+workflow files.  Features include:
+
+@itemize
+@item Syntax check for workflow files to check unexpected or missing
+keys following workflow syntax
+@item Strong type check for @code{$@{@{ @}@}} expressions to catch
+several semantic errors like access to not existing property, type
+mismatches, ...
+@item Actions usage check to check that inputs at @code{with:} and
+outputs in @code{steps.@{id@}.outputs} are correct
+@item Reusable workflow check to check inputs/outputs/secrets of
+reusable workflows and workflow calls
+@item shellcheck and pyflakes integrations for scripts at @code{run:}
+@item Security checks; script injection by untrusted inputs,
+hard-coded credentials
+@item Other several useful checks; glob syntax validation,
+dependencies check for @code{needs:}, runner label validation, cron
+syntax validation, ...
