LLM output is just very predictable. If you spend 200$ on that /goal you will get some output. It may or may not work perfectly, but there will be a repo with some progress. If you specced the goal well and it is feasible, a decent model will most likely get you decent progress.

Also who would take on any of these projects for a meager 200$? Most of that stuff is borderline interesting, clearly not interesting enough for the people proposing the things to start working on them themselves.
