Commit signing is a git feature, so git itself can be used to check your last commits are signed:

git log --show-signature

This will look the same as git log if the commit is unsigned, and show the result of gpg —verify otherwise. Red background if unverified (eg. you don't have the public key) and green otherwise. This should zake it easy to spot whether you signed the last commits or not
