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!
