I respect your decision but AGPLv3 is very restrictive. Anyway it is up to you.

"The most common misconception about open-source projects is if a Github project has no license then it’s okay to use. If a repository has no license, then all rights are reserved and it is not open-source or free. You cannot modify or redistribute this code without explicit permission from the copyright holder."

I don't see any LICENSE file in the repo. So, if you want more people to engage with your code, please add a LICENSE file to your repo.
