In my use case I use it to make PRs for ArtCraft, the Adobe Suite clone that is viral right now. This tool got me into the top 10 contributors within 5 days. I have 361 total pull requests, 234 of them got merged. I think that statistic speaks for the quality this thing can achieve. Right now on low usage settings it's round about 51 pulls a day fast, and it does not use up as much usage as you think it would, mainly because the tasks get split between Haiku models on default settings and not everything is running on one big Opus session. Also they get optimal prompts and clear instructions every step, which further reduces token usage. It can also bughunt: about 60% of pulls are code problems the tool found by itself.
If you are a GitHub contributor to any project or want to solve issues on your own repository, this is the tool for you.
