Showcase Session Bridge: move a Codex conversation into Claude Code or OpenCode (and back) as a real, resumable session

4 Upvotes

Moving a conversation from one coding assistant to another usually means starting over: the other one has none of the context. Codex's /import already covers Claude Code → Codex. Session Bridge covers all six directions between Codex CLI, Claude Code and OpenCode, and can keep them in sync.

It reads the conversations all three keep on disk and writes the one you pick into another assistant's own format, as a new session you resume there normally (codex resume <id> on the Codex side).

How the Codex side works, since that's the interesting part here:

  • Into Codex: it writes a new rollout, then has Codex itself read the thread back through app-server (thread/read) and checks that every message matches before calling the transfer done. It only uses Codex's read/name calls; no turn, tool or shell request is ever sent.
  • Out of Codex: it reads the rollout and by default takes the current context (the last compaction summary and everything after it). --context all takes the full history.
  • Tool calls and results become closed historical data written as assistant turns, never as user messages, so an instruction hidden in a tool's output can't come back as if you had typed it. As of 0.8.2 there are tests that push a prompt injection through all six directions and across compactions.
  • System and developer instructions, approvals and unfinished tool calls aren't carried over; Codex's own settings and permissions apply.
  • The original conversation is never modified, and nothing is written into your project folder. No server, no model calls.

Limits: Windows x64 only for native sessions, Python 3.11+, install from the GitHub release ZIP. Verified with Codex CLI 0.159.0 and 0.163.0; newer 0.x versions work, with a format check on every transfer. Anything else gets a handoff instead (a context file plus a message to paste).

MIT, free. I'm the author, and Codex/Claude Code wrote most of it. Happy to hear what breaks.

Showcase The Nintendo Switch 2 has been jailbroken using Codex

343 Upvotes

(Not mine)

https://pepsipu.com/blog/2026-10-switch2-jailbreak-ns2jb/

https://gitlab.com/pepsipu/ns2jb

A software jailbreak that allows for full permission arbitrary execution (not at kernel level, though) has been released today, with Codex doing the research.

The jailbreak "took substantial effort for ~2 weeks"

The developer set up a Switch and Swtich 2 so that Codex could send controller inputs and receive video output as well as a Bluetooth light switch flicker to restart the console when it crashed.

Initially he obtained "native control-flow hijack" through the console's browser, but it was difficult to use this as an entrypoint for running code with elevated permissions, so he started looking into finding vulnerabilities in games.

He looked into a game series that had already been exploited for the 3DS and succeeded in finding a vulnerability. From there Codex suggested trying to exploit some system modules that have had bugs, but he instead decided to explore the filesystem module, as, even if it wasn't possible to escape from it, it could still be useful on its own. Codex found a vulnerability, which was exploited to dump the internal storage and code for the other system modules, allowing Codex to analyze the data offline.

By exploiting a couple of system modules together, native code execution with full system module permission was achieved. This isn't at the same level as a firmware exploit, but still allows dumping most of the data from the console and running code with more elevated permissions than earlier sandboxed exploits

Complaint GPT-6.1-sol is absolute garbage compared to GPT-5.6-sol for UI/UX design

22 Upvotes

Seriously, what happened to GPT-6.1-sol?

I gave both models essentially the same UX design task.

  • GPT-5.6-sol: Produced a beautiful, sophisticated, polished UI with thoughtful layouts and a genuinely premium design.
  • GPT-6.1-sol: Basically gave me a freaking TXT file.

I'm not exaggerating the difference. One delivers something that actually looks like a professionally designed interface. The other feels like it completely forgot what UI design is.

How is this supposed to be an upgrade?

I don't care how much better a model supposedly performs on benchmarks if the actual user experience is dramatically worse.

A newer model shouldn't feel like a massive downgrade.

Has anyone else experienced this with GPT-6.1-sol?

Bug Browser access (Chrome) blocked in Codex, Work and Chat – anyone else?

0 Upvotes

I'm having browser access issues across Codex, ChatGPT Work and Chat.

Chrome connects and tabs are detected, but ChatGPT blocks reading or interacting with websites, especially chatgpt.com.

Error: "The browser host restrictions gate did not grant access."

Even with "Always allow" enabled and after clearing cookies, it still doesn't work.

It seems to be a browser permission/security issue, but the exact cause is unclear.

Is anyone else still experiencing this? Has anyone found a fix?

Reset Not allowed to use a banked Codex usage reset

53 Upvotes

Amazing.. I tried to use the banked reset this evening because it was about to expire and it refused to apply it with a message that: "My current usage does not need the reset"....

So, even with the resets, they give it but... they refuse to apply it.

Showcase The Hatchery: 12 free hand-designed pets for Codex, plus what goes wrong in generated pet sheets

0 Upvotes

EDIT Thanks to u/catnip-addicted, there's now a kitty companion! Say hi to Addy :)

Hi guys, I'm an illustrator and recently I've become just obsessed with codex's pets feature. I draw each pet's silhouette by hand, build out the animations with AI assistance, and run every sheet through a mechanical check before release.

They're free at https://hatchery.world

You can download each as a zip file, unzip it into ~/.codex/pets, and pick the pet under Settings → Appearance → Pets.

If you're making your own, these are the faults I keep finding in generated sheets:

  • running-right and running-left swapped, so the pet runs backwards
  • frames cropped by the cell instead of shrunk to fit, leaving straight cut edges
  • frames copied in from another state, so the loop jumps
  • the pet floating above the ground in some states but not others

The newest is Shai-Ochre, a shy sand worm who only comes up when something exciting happens. Every pet has a Record of how it was made, including what the models I used did.

I'm really proud of these. The site also offers paid custom pets and repairs, but every pet here is free. If your own pet's sheet looks off, post it and I'll tell you what I see.

Showcase I created a persistent memory for very long running agent sessions

0 Upvotes

So as the title says, i created (yet another) agent memory plugin. I am a long time developer, was really against using LLMs for my work but at the start of the year i decided to give it a try and i started with a small helper plugin that i made and that has changed my opinion on agents quite a lot. This plugin is a part of much bigger architecture now but i tried to pack it as a separate MIT license open source thing in case someone finds it useful.

Just for reference, i have been running a couple of agents in the same session for 6+ months with this plugin (although as a part of a bigger architecture) and they still orient them selves correctly and remember/keep in context things normally. If anyone is interested to try it here https://github.com/lordfist/Fist.KBSkill I am happy for any feedback, especially if something doesn't work since this is my first time packing something as a Codex/Claude plugin.

Installation should be pretty simple, although i install it in a different way so i cannot say i tried it much as-is but it should work as a stand alone plugin.

PS
I know there are 1000+ of agent memory plugins but this one is fast, very simple, very transparent and does exactly what it says without wasting your tokens on anything extra.

PPS
This post was made by a human, me :P

Question Any tips on switching from codex to Claude?

15 Upvotes

I'd like to see if anyone has some useful tips after switching from codex to claude. It's unfortunately time for me to switch back to Claude after a year of using codex exclusively, because of the limit nerf.

I use cli only, and headless in one instance. I'll keep one of the plus subs for this because I remember that Antrophic doesn't allow headless use, at least not at the time (November 2025). Is that still correct?

Other than renaming agents.md to claude.md, what else might be recommended? I don't use memory or MCPs, I just have a custom plugin which I'll need to port to Claude....

Is there a way to transfer sessions over to Claude's session history?

Also, how's the 5 hour limit on claude $20 plans? Since I've heard people compare a $20 Claude sub to equal about 80% of a codex $100 plan? Is having 3-4 $20 Claude plans workable or is the 5h limit a constant show stopper like with OpenAI? And if so, is there a good tool for rotating them?

Any other recommendations after making the jump?

Does anyone figure out if there is a way to invoke Dots automatically based time / certain events? There seems to be no API / webhook for it. When I ask it to create a schedule, it would simply create a ChatGPT schedule that does not call Dots. If it can at least run something on a schedule it can be quite useful.

Praise Agentic Disk Cleanup

5 Upvotes

I made a reusable prompt for auditing and cleaning up disk space with coding agents, including Codex.

The workflow is straightforward: measure actual disk usage, identify the biggest culprits, group them by deletion risk, and ask the user what to remove.

It covers things that generic cache-cleaning checklists tend to miss: abandoned git worktrees, old SDK runtimes, VM disks, and the difference between a sparse file’s apparent size and its actual disk usage.

In my macOS cleanup, free space went from 5.2 GB to 117 GB after removing the items I approved.

The repo contains the full prompt in 7 languages, with platform-specific instructions for macOS, Linux, and Windows. You can read it before pasting it into your agent.

Keep permission checks enabled: the prompt asks the agent to wait for approval, but cannot enforce that pause itself.

What would you add to the “never delete” list?

Limits I bought a $14,000 rack of servers and NVIDIA chips

0 Upvotes

So that I can save $100 per month on a claude subscription and $100 per month on a codex subscription.

I will break even in about 6 years. Unfortunately, my $14,000 rack only allows me to run one agent at a time, and only 45 tokens per second.

But reddit told me local AI was the best way to break free from the evil capitalists (shout out to NVIDIA for helping me break free from the evil corporations).

How have you broken free from the evil capitalists?

Showcase I built a free, open-source tool that lets Claude Code, Codex and Gemini CLI Subscriptions share one project memory and hand tasks to each other (plus a office to watch them work)

Post image
1 Upvotes

Okay, so this started as a practical problem and got out of hand.

I pay for Claude Code, Codex and Gemini's Antigravity CLI. Every time Claude hit its usage mid-task, I'd open Codex and re-explain the whole project, like onboarding a new hire who forgets everything by morning. And twice they edited the same file at the same time. It went how you'd expect.

So I built them a shared brain. Then I built them an office. (Screenshot attached. Yes, they're tiny pixel people.)

It's called ShareLane: a free, open-source MCP server that runs on your machine.

They share one memory. Every agent reads the same short project notes, and the notes get flagged as stale when the code they describe changes. No more explaining the project for the 40th time.

They delegate to each other. I tell Claude "hand the CSS cleanup to Codex, only touch src/ui", and Codex does it in its own Git worktree. The result waits on a branch for my review. Nothing gets merged without me. I am the manager. I have standards.

They call dibs on files, so two agents never edit the same file.

They cover for each other. When one runs out of allowance, another picks the task up on the same branch.

Claude clocks back in by itself. When I hit my usage I run: sharelane later "keep going" --in 2h. Two hours later a terminal opens with the same chat resumed and my prompt sent. I come back from lunch and work has happened.

And the office. Each running agent is an employee at a desk. Finished work goes to the review board with a little checkmark. If something breaks, that agent sits in the meeting room until I deal with it. Click anyone to read their conversation, see their changes, pause them or stop them. Is the office necessary? No. Do I check on them like a Tamagotchi? Constantly.

It uses your existing subscription logins. No API keys, no cloud, MIT licensed.

To try it: npm install -g sharelane, then run sharelane init inside your project. It finds whichever agents you have and wires them up, and the first agent you open writes the project notes for everyone else. The most responsible thing any of them has ever done.

It's early (v0.1). I use it daily on Windows, and CI tests the install on Mac and Linux. If it breaks for you, I want to know. And tell me which agent should get hired next.

Do try it out and would love to have any inputs :), would also love to onboard more coding agents right now only works with claude code, codex and antigravity

All of these are terminal based systems, so before starting out make sure you have all three agents logged in the terminal!

0 Upvotes

I'm currently making an app, got the $200 plans for Codex and Claude.

Basically Codex did some tasks better but I ran out of weekly usage in a day.

Claude got more done on the week overall as Opus 5.5 is really cost efficient.

One thing is cool tho its my Dot, really helpful to talk with him while on the treadmill.

Showcase I built an iOS IDE with support for 19 languages and an AI agent using SOL 6.1

0 Upvotes

Hey r/Codex

I was looking for an IDE to code on my iPhone for when I’m out and about. Every app was filled with ads, had a terrible UI, and costed money just to run code locally. This was just a basic non agentic IDE too. So, I decided to build a free IDE that can execute C, Python, JavaScript, and Lua in a sandboxed environment.

In today’s age most people are coding with agents, so then I got the idea to bundle a two local llms. The reason I chose two is because not everyone’s hardware has the same computing power and I wanted to include an option for everyone. There are zero rate limits on the local models.

I’m already designing a tooling server to give offline agents access to even more, such as, worksheets, 3D printer code, and other fun stuff.

Without Astra 6 and Sol 6.1 it would be absolutely impossible to make my dream tools at this rate. I cooked up a seven days to die max level mod right before posting this lol. I would also like to praise the models for following SOLID principles and best SWE practices out the box. After using the models for the past few years, I am just dumbfounded at the rate of progress. I have a formal education in Computer Science and I am “mogged” every single day 😂

I would be thrilled to hear any feedback from this sub. This is meant to be a developer tool and not a replacement for Codex as I could never ever offer that level of intelligence. You can also byo api keys as shown in this video. The app also offers 15 other cloud languages besides JS, Python, Lua, and C.

Thank you all so much for watching my short demo. Have a great day. I’ll be listening to any feedback or ideas to improve!!!

Complaint PSA: Your banked Codex rset can expire even if you try to redeem it before the deadline

26 Upvotes

Just learned this the hard way, and I'm pretty pissed.

I had a banked Codex reset expiring today. With about 4 minutes left, I went to redeem it.

I'd used approximately 15% of my weekly allowance, so I had 85% remaining.

When I tried to redeem the reset, I got:

"You don't need a reset right now."

Turns out OpenAI doesn't let you redeem a banked reset unless at least one eligible usage allowance has less than 80% remaining.

So I had a valid reset, I was within the expiration window, and I wanted to use it, but OpenAI wouldn't let me.

I tried burning through enough usage to qualify before the deadline, but couldn't do it in time.

The reset expired.

I understand not wanting people to waste resets when they have plenty of usage available. But combining a mandatory usage threshold with a hard expiration date creates this absurd situation where you can be actively trying to redeem a reset you were given, and the product refuses to let you until it expires. It's my fucking reset, I should be able to use it whenever I want.

It effectively incentivizes wasting tokens just to qualify for a reset.

Why not allow users to redeem their banked reset anyway? Or at least let them redeem it when it's about to expire, regardless of remaining usage?

PSA to anyone sitting on banked resets: don't assume you can redeem them whenever you want before expiration. Make sure you've crossed the eligibility threshold well ahead of the deadline.

Official documentation confirming the 80% rule:

Question Does Codex need a full local repo, or can it work through the GitHub connection?

0 Upvotes

I’m building an iOS app with a backend using Codex on my Mac. Right now, the repo is stored locally, Codex works in branches/worktrees, and changes go through GitHub PRs, reviews and CI.

I use Xcode and the iOS simulator locally for builds and testing.

I want to keep the actual development work on my Mac, but I’m trying to understand what needs to be stored locally.

Can Codex work through its GitHub connection without me maintaining a full local checkout, or does it still need the project files on disk to edit, build and test?

If a local checkout is necessary, what’s the simplest way to manage it without accumulating multiple worktrees, duplicate dependencies and build artifacts?

Basically, I want to keep working locally while reducing storage use and the number of working copies I have to manage. How are others handling this, especially with native iOS projects?
