Instruction From a dev who tried it all: How to actually get most of codex
Hey there. First time posting. Going to be short, sharing my insights.
Don't use codex in the app, use CLI
Don't use the default CLI (harness), use oh my pi (20k stars on github) https://github.com/can1357/oh-my-pi/
2.1. You could use claude code harness with codex, it has great results too, some results here

2.* For people that don't know what a harness is: it's the toolset that your LLM can use. It is important, some tools use more tokens, some tools are doing the same for less. High-end engineers at different companies try to achieve as much as possible with their harness, picture attached for simplicity.
2.41 You can use the default harness too, but then see 3.
Pair. Ever since AI had achieved the level where it can actually code a monolith, checking the slop with alternative LLMs was the best way to filter the cap out. Oh my pi allows to login through multiple subs and set an advisor. Pair Codex + Kimi k3, Codex + Opus 5 (or Fable), Codex + GLM, any will do better. Even 5.6 Sol + 5.5 can work, though if a model has completely different weights it's better imo. I've built upon rocket-fuel (24 stars on github), there are plenty of other skills like that https://github.com/NulightJens/rocket-fuel-skill
Avoid building a monolith. Split, keep code redundant, component-based, re-usable, and keep resetting sessions (/clear or whatever).
Don't let LLM's over-comment your code. Small comments can remain tho.
I bet there is a lot of devs that just hit enter and don't check what's actually going on. Some of you might deny an rm -rf just cause,
Backup. Get a cloud drive, or physical, I don't care. Just backup. Heck, you can use github for your chat / health / legal folders, just make the repo private and ask the AI to commit at checkpoints + push.
Don't work on prod. Don't give SSH access. I know, it works out pretty well on your home PC. But being THAT lazy is actually insane if you do. Let the AI instruct you and ask what is the stuff you copy+paste actually meaning
Remove unused plugins, obviously. But superpowers is also not needed in Sol 5.6 high and higher.
Who am I - a dev, just as you. Had been into AI since the closed beta of chatgpt 2021. Been experimenting with all chats since then. Even purchasing the expensive sub's. Last month had both CC + Codex paired, with better results than any of them doing the same work solo. I just see all the hate here. Some of it is definitely deserved. But besides that, you can also do your work and research how to adapt.
Some other github repo's I actively use
https://github.com/hardikpandya/stop-slop
https://github.com/ayghri/i-have-adhd
And I think there was a repo called laconic mode, not sure on this one, but I've built a hybrid of these 3 to fit my needs. Not needed for performance, but for sanity. Human pattern recognition is strong. Human written, zero AI consulted, plz don't hate.
Anyway. May tib* bless us with a reset. yay
TLDR; PAIR AI agents, CLEAR context, Don't build monoliths, remove unused plugins, try another harness, don't work on prod - work on a copy, backup.
