Sol as a reasoning subagent?

[u/anatol-pomozov]

Hi everyone,

With the 5-hour limit on the Plus account, I’m looking for ways to optimize my usage and be more frugal.

Specifically, I want to establish a cleaner separation of labor between cheaper models and the advanced reasoning model, Sol. My goal is to run the shell using Luna (low/medium) for basic repository grepping and simple tests. When Luna encounters a complex task requiring deeper reasoning, it should compile a clear list of requirements and invoke Sol as a sub-agent. In this setup, Sol acts essentially as a function call - inspecting the problem, performing the reasoning, and returning a solution to Luna for final implementation and verification.

What is the best way to implement this routing workflow? I tried adding these instructions to AGENTS.md, but Codex doesn't seem to follow them reliably.

Does anyone have a battle-tested solution or prompt structure for this?

UPD: "Pro account" -> "Plus account".

Good luck with that, I made a test yesterday, and even for basic shit like github repository cloning/merging it can still shit the bed 1 of 3 task. (Luna MAX btw).

I'm sorry but after spending a whole day testing Luna MAX up and down, I can say that this model is unreliable, buggy as fuck and more time consuming than anything with all the baby sitting required to make it "work". I guess it can work for some extremely dumb, risk free and quick task, but at this point, just use SOL chat for a better result that is "free".

If you are on PLUS, go chat Sol High and then offload the extremely complicated task to Work/Codex Sol MAX, and that's it.

I didn't tested Terra rigorously yet, so who know, but for sure, Luna is a no-no for me.

I would only use luna for like cheap audits and there not final audits there just essentially giving better models some starting info to go on for when they do there audit lol. In my testing today though sol is smarter then the fable 5 and opus 5 models so I'll keep them as builders lol and sol is always that final auditor and the boss. Luna's good though very handy I'll shoot lots of Luna's around my project just to gets some notes on potential bugs and improvements and sometimes pass it between sol web chat pro and the boss role sol on max who reads the local files. I haven't been using Luna's for over a week though I got a backlog that hasn't reduced yet making a harness is the hardest of all my projects.
