When I used to play Screeps[1], a MMO strategy game where you programmed to control your units and buildings, a group of us setup a player that was managed in this exact way called Quorum[2].

If anyone wants to run their own project in this way I open sourced the code to do so under the GitConsensus[3] project. There's a Github App (which may not still work, but if there's interest I'll restart it) and a "run it yourself" python library and CLI you can run from Github Actions[4].
