    Anyone created an agent skill for splitting PRs for good review culture?

    GPT 5.2 xhigh feels like a much more careful architecter and debugger, when it comes to complex systems But most people here think Opus 4.5 is the best model in that category There are 2 reasons AFAIS: - xhigh reasoning consumes significantly more tokens. You need to pay for ChatGPT Pro (200 usd) to be able to use it as a daily driver - It takes like 5x longer to finish a task, and most people lack the patience to wait for it. (But then it's more correct/doesn't need fixing) Opus 4.5 is good too, I think better in e.g. frontend design. But if you think it beats GPT 5.2 in every category, you are either too poor/stingy or have ADHD

    Just 5 months ago, I was swearing at Claude 4 Sonnet like a Balkan uncle Models one-shotted the right thing only 20-30% of the time but did really stupid things the rest, and had to be handheld tightly Today they are much, much better. My psychology is a lot more at ease, and instead of swearing, I want to kiss them on the forehead most of the time Now I trust agents so much that I queue up 5-10 tasks before going to sleep. They work the whole night while I sleep and I wake up to resolved issues GPT 5.2 xhigh and Claude 4.5 Opus are already goated (GPT more so), can't wait for them to get even faster

    Codex does not have support for subagents. I tried to use Claude Code to launch 8 Codex instances in parallel on separate tasks, but Opus 4.5 had difficulty following instructions So created a CLI tool to scan pending TODOs from a markdown file, and let me launch as many harnesses as I want (osolmaz/spawn on github) I currently use this for relatively read-only tasks like planning and finding root causes of bugs, because it's launching all the agents on the same repo and they might conflict Ideas: - Use @mitsuhiko's gh-issue-sync and run parallel agents directly on github issues - Create any new clones or worktrees for each task. I currently don't do this because I don't dare duplicate rust target dir 10x on my measly macbook air - Support modes other than tmux, e.g. launching a terminal like Ghostty - TUI for easy selection of issues/TODOs Other ideas are welcome!
