+# Audit Argument Checks
+
+
+This package causes Meteor to require that all arguments passed to methods and
+publish functions are [checked](#check). Any method that does not pass each
+one of its arguments to `check` will throw an error, which will be logged on the
+server and which will appear to the client as a
+`500 Internal server error`. This is a simple way to help ensure that your
+app has complete check coverage.
+
+Methods and publish functions that do not need to validate their arguments can
+simply run `check(arguments, [Match.Any])` to satisfy the
+`audit-argument-checks` coverage checker.
