class Overcommit::Hook::CommitMsg::GerritChangeId

Ensures a Gerrit Change-Id line is included in the commit message.

It may seem odd to do this here instead of in a prepare-commit-msg hook, but the reality is that if you want to ensure the Change-Id is included then you need to do it in a commit-msg hook. This is because the user could still edit the message after a prepare-commit-msg hook was run.
