I know, right? The day I initially thought about posting this, there was another one called `yolo-box`. (That attempt--my very first post--got me instantly shadow-banned due to being on a VPN, which led to an unexpected conversation with @dang, which led to some improvements, which led to it being a week later.)
I think it's the convergence of two things. First, the agents themselves make it easier to get exactly what you want; and second, the OEM solutions to these things really, really aren't good enough. CC Cloud and Codex are sort of like this, except they're opaque and locked down, and they work for you or they don't.
It reminds me a fair bit of 3D printer modding, but with higher stakes.
