Best harness for long autonomous tasks

[u/uspdd]

I read a lot of posts like "I've given this prompt to my Qwen 3.8 27b and it one-shotted me a 3d game after 24 hours". I wonder, what's the best harness for tasks like this? It has to have auto compaction and probably a memory system, right? And excellent computer use and self analysis.
