Use the check to notify you when the 8-4-4-4-12 pattern of UUID or GUID is not followed when creating a changeset ID. The 8-4-4-4-12 UUID or GUID pattern is straightforward, but also easy to mistype, which can cause failures in other tools down your chain which count on a valid UUID or GUID. This policy check, like other checks, can be configured with a severity level which returns an exit code designed to stop automated jobs, giving your team time to make sure simple mistakes are not deployed.
