The Glasgow schoolboy further shot to prominence after coming off the bench for the final nine minutes of the victory over their Tynecastle counterparts at Cappielow in the SPFL Development League.
And Chris McCart, the club’s Head of Youth, promised to take care of the prospect’s career progress.
He said: “We were all delighted to see Karamoko make his debut for the development squad against Hearts in what proved to be an entertaining game.
“The fact that he was playing against other players seven years his senior gives an indication of the quality this young boy possesses and it was also fitting that he came on for Jack Aitchison, the club’s youngest-ever player and goalscorer.
“What we need to remember, though, is that Karamoko is just 13 years old. He was given a chance to play on merit, as was Kieran, but it is very important that we continue their development at a measured pace.
“Karamoko is still a young boy and has a lot of growing to do, both physically and mentally. The coaches at our under-13 and 14 levels have been fantastic in nurturing his potential but it is crucial that we do not push him too far, too soon.
“He has a lot of hard work ahead of him to make it to the top and we won’t rush that, but we also know Karamoko, and the other talented young players we have here, is at the perfect place to continue his progress and we look forward to seeing what the future holds for this young player.”
