> What kind of tasks do you use it for

There are some bugs that just seem to elude Opus and GPT 5.5. An example is an Elixir/LiveView app that I wrote for personal use that basically gives me a full tmux in my browser from the system it's running on (very useful for VMs or when on-the-go on mobile and need to run a quick command or two). On mobile the scrolling is complex and janky and even Fable struggled to figure it out, even with me spoon feeding direction.

The bugs didn't get fixed. I tried, oh did I try. New bugs (worse than the one fix) introduced, other things breaking, etc. I just lived with the bugs or fixed them myself.
