Commit Co-Author Footer

Run this check on every commit message, including one with an empty body, after formatting the subject and before committing.

Configured git user email:

!git config --get user.email

• If the email is exactly agent@nonhuman.work, leave the message unchanged.

• Otherwise, including when the email is missing, end the message with one blank line and this exact footer, unless it is already present:

  Co-Authored-By: Agent <agent@nonhuman.work>

This skill only manages the footer. It does not detect commit style or format the subject.
