Autonomous Skill

It sets up a dual agent pattern where an initializer breaks your request into a checklist in `.autonomous/<task-name>/task_list.md`, then executor sessions work through items one by one, auto-continuing every 3 seconds until done or you hit Ctrl+C. The `run-session.sh` wrapper handles everything: starting new tasks, continuing existing ones, even resuming the actual Codex session with `--resume-last` to preserve conversation context. Honestly most useful for tedious multi-file refactors or scaffolding work where you want to kick it off before lunch and come back to progress. Just know it uses whatever model is in your active Codex profile, and you'll want to add `.autonomous/` to gitignore.
