I have some significant experience in context engineering, but I'm most familiar with Codex as a coding harness right now. Sam Altman said "you don't need to write prompts anymore". This has widely been panned as something someone selling AI would say. If you care about the output and how much time/money it costs to produce it.. Just giving Codex an abstract tasks with zero extra guidance isn't going to produce the best results..

Codex Astra can do a great-(ish) job as a project coordinator dispatching tasks to a pool of 6.1 Sol sub agents. You can even give it an explicit goal and ownership over ensuring the work is carried out efficiently.

However the OOTB harness(and prompt) configuration may not do this for you. You'll have to provide guidance over how you want it to operate through your prompt, a skill, or etc.

And I'll say even though it's really good at this.. Having even more layers than 2 can help; a single agent given too many responsibilities will start to become fixated on a number of them while neglected others. You can check in occasionally to "nudge" it or you might need to split out responsibilities more..

I will say it's crazy Codex doesn't have more built-in task and sub agent management features. I almost wish that it had some stock orchestration patterns that worked OOTB, and then you could opt-in to a leaner setup where you provide more of the instruction.
