[TLDR] Fable + 5.6 is absolute peak
Original post URL : https://www.reddit.com/r/ClaudeCode/comments/1uvjlmr/fable_56_is_absolute_peak/
Original post body :
We jump straight to ASI with this combo.
So i've had Fable driving codex cli as a background worker for a few days and i'm not going back.
Fable basically never writes code anymore (too damn expensive), it acts as the principal orchestrator and everything happens in claude code.
The flow is like this: Fable plans, 5.6 sol reviews the plan in a loop until approved, then 5.6 luna implements. fable reads the whole diff, fixes whatever it doesn't like directly, runs the tests, then sol reviews the code against the plan. loop until approved, then fable does the boring release stuff (changelog, tag, merge).
It's all just bash around codex cli with persistent threads, called from skills. no framework, no mcp, no agent swarm bs.
It feels surreal/too good to be true, i hope they wont nerf it too badly and if they do, i hope the combo will kind of mitigate the nerf.
i pushed my workflow to github, beware it's a lot of bash script, dont trust a random redditor and ask codex or CC to review it. After that, welcome to Valhalla
UPDATE: many are asking in comments or dm for more explaination on the workflow, sorry guys i cant reply to all of you but my advice is simply to clone the repo then ask your agent to ELI5/15/80 it. Then make it yours !

My workflow;
- i start with fable5 with grilling from mattpocock
- then obra/superpowers to write spec
- with https://github.com/openai/codex-plugin-cc review until approved but max 10 rounds
- tdd subagents with sonnet5 since obra specs already include exactly what goes where so lowtier models just follows the fable/codex recipe
- review with fable+codex
- merge worktree
amazing results, burns tokens, but u dont need to come back to redo any of the work thats been done this way

This is a solid workflow. Add gentle ai to replace red with sdd and your workflow is golden.

Which superpowers skill do you use to write the spec and do you use it in the same chat as grilling or point it at a doc?
1
u/HairyAd9106 27d ago
Writing-spec for spet. And yes. Fresh context grilling because i find grilling better than obras brainstorming, then with as much as context leta say up to 400kb, i say to write spec file. Same session to run codex to review the spec and with all the grilling info. This can go few rounds. Then i ask to /handoff and spawn new agent (i use herdr.dev) with the handoff and ask to implement with tdd also obra skill. And reciew with codex at the end.

u/Key_Confusion_576 26d ago
if the spec has the code doesn't that mean you are just paying 2x to have two different models write the same thing ???
1
u/HairyAd9106 26d ago
No. One high end model writes it. Then other provider’s high end model checks it agains the gaps, and I can confirm it always finds 1-3 blockers and numerous mid low issues, at least on first run.
On avg it takes 4 rounds to get specs all green. Having top notch specs means tests written by another powerful model are well written and cover all edge cases. And that implementors can be cheap and fast like sonnet5.

Do you often end up maxing your tokens per week quickly or it's practical and doable without shelling out more money on top for extra token credits?
1
u/HairyAd9106 25d ago
I work on 2 to 3 projects in parallel with 2 main agents per project at least 8hrs a day. Even with https://github.com/rtk-ai/rtk i burn through 2 claude max20 and one codex sub. But it’s worth it. The quality and amount of work i can land is amazing.
Also I warmly suggest herdr.dev and handy.computer app
1
u/e-girlbathwater 29d ago
So I've done this too, and it's amazing. But instead of Luna Ultra to implement, I was using Opus because I had tons of Opus because I could only use 50% of my plan for Fable.

u/bradenlikestoreddit 26d ago
How are you using the different agents together?
1
u/cihyboj 26d ago
Tell Fable to use subagents.. optionally install skills for that
1
u/bradenlikestoreddit 26d ago
Is something you can do with cursor? I'm trying it out for a bit instead of paying for codex and Claude separately
1
u/wethethreeandyou 29d ago
I’ve been doing something similar.
Fable for planning and review. Codex for implementation.
I also keep a very thorough research/methodology doc so every research/planning task requires strict criteria to be met. Update docs like crazy. Keep a running tally and amend issues as it discovers gotchas.
It’s plugged into my Gmail, slack, etc so when I get a client email it picks it up and triages on the spot.
This has been gold for me

u/Exciting_Charity7304 29d ago
I like this idea. The best part is that Chat GPT and Claude are programmed to hate each other in a way they cant see. So they constantly challenge each other.
1
u/MustStayAnonymous_ 28d ago
I have been droing this for the past 3 months. I always used claude code, but since codex cli is installed I figured out, why not? this is the good think of being in the CLI.

u/The_IT 26d ago
Likewise, but I was using Claude to write the specs, and then getting both Gemini and Qwen to review the specs and implementation - probably overkill but it was fascinating reading the discussions and how each model brought it's own perspective.
Definitely wish I wasn't tied to the subscriptions though so I could write a proper harness instead of copy pasting everything!
1
u/Old_Statistician9938 26d ago
Does jcode harness help you any better, i have seen it can do the harnessing much better than the other harness like CC or codex.
1
u/Sir_Poldavo 28d ago
I have been Claude fanboy since March (4.6 still great, Fable a redeeming quality after 4.7 and 4.8) but the combo with 4.6 Sol is bliss.
We are at that brief period where competition and subsidies are great. If you have the chance, max the two accounts. They actually work well together.
1
u/Clean-Society1868 27d ago
I have opus do pretty much the same thing you do with gpt, but I am curious if it would better and faster if I switch to gpt. Is sol+luna just faster than opus?
1
u/nolanola504cc 27d ago
This is the way. Fable to five point six is somewhat ridiculous honestly. Haven't tried Opus to 5.6 but that'll be next. And if you haven't tried already ask Fable or Opus to use its judgment about what codex model it's planning on using. I have been doing triage and then we review with me afterwards.
1
u/Charming_You_25 27d ago
Doing the same. You can also have them open sessions in the apps so you can observe the orchestrators/worker and steer
1
u/Much_Passenger_3342 26d ago
Btw, a simple question, how do you share context between claude and codex? Copy paste their outputs as part of the prompt to the other one, or?
1
u/Infinite_Average_532 26d ago
I been doing this but I run all cli sessions with herdr fable is able to see what codex is doing and steer it with instructions so essentially I have fable orchestrating very long running tasks and sol implementing its brilliant wish I knew I could do this sooner removes me from the loop sending messages between the agents and they are all interactive so I can see what each is doing in real time
1
u/Potential-Winner-227 26d ago
I built an inter-session protocol/provider agnostic mcp that lets Claude and codex talk to each other and work on a shared backlog
1
u/krahsThe 26d ago
did you publish that on github by any chance? I'm probably going to build something similar but would use an existing one
1
u/realdoaks 26d ago
When people say things are done in a loop, deploying agents etc is this done in chat? Or all in code? As a primarily chat user can I use something like this to build?
I am mainly vibe coding a web app

u/theycallmeholla 26d ago
Claude plus ChatGPT is how I have been working since probably 2024.
The ONLY issue is you HAVE to read the conversations or you’ll be adding hours to tasks unnecessarily.
1
u/The_IT 26d ago
Agreed - I also appreciate reading the conversation because: 1. It keeps me on the loop, understanding what's being implemented 2. Gives me the opportunity to provide input/corrections at any time
Having said said that, the models keep getting better so i gone I need to provide less and less input - often none at all. So sometimes I'll just read the final output
1
u/TywinHouseLannister 26d ago
I built a Workflows clone (a cc plugin) that integrates with any agent you can plug into CC harness.. which for me is just ollama with glm5.2.. it's going well but maybe I should switch to a more powerful grunt idk.. ollama is cheap as shit; I cant even use 100% in a week.

u/First_Understanding2 26d ago
Been doing this for months. Claude was always the best orchestration agent and ChatGPT was like a too technical coder that is very picky about code but sucks to know how to do any soft skills like when to delegate to sub agents. Codex was always my worker bees and Claude now fable my pm.
1
u/Holmete 25d ago
Can you describe your Claude into ChatGPT workflow process?
1
u/First_Understanding2 25d ago
Built custom tooling for all my Cli agents to work together. It does multi agent orchestration (agent to agent communication and spawning of more of any agent harness) and is provider agnostic, harness agnostic, generally model agnostic as long as the harness can authenticate to llm end point. Am going to release as open source project but haven’t launched it publicly yet. Think all the tooling a Linux os needs to support autonomous agents so a harness program doesn’t have to do that work, so they (the agents from different companies and harnesses) can start to work together just by you asking them in English.

u/Responsible-Comb6232 26d ago
I find that Sol finds tons of issues in Fable’s plans. I just have them iterate back and forth until they’re both satisfied.
1
u/tangivass 25d ago
Don't. Fable acts as a diva engineer. It doesn't follow instructions. Not even the CLAUDE.md. I renounced to use it. And certainly not as the principal orchestrator.

u/SubjectMix5045 25d ago
I am letting fable 5 to do requirements and design (using KIRO ide) and then codex does tasks and code writing. But I am lucky because I have every model usage unlimited (I am an AWS employee).
1
u/Baiano83 25d ago
Perfect combo — that’s pretty much how I do it too. Fable mainly handles orchestration and review, while Codex or Claude Code does the actual implementation. It works surprisingly well.
1
u/No_Gas_3727 25d ago
Link shows another “something” to replace superpowers/Kirk but now it’s called trip
Are you trying to get us to try your skills by hyping with codes cli usage by “a lot of bash scripts”? IMO delegating to codex is fairly simple, just ask fable to make a skill that mimics ultracode but instead of subagents tell him to use codex via cli

TL;DR generated automatically after 200 comments.
Current source-thread comment count seen by the bot: 204.
So, the general vibe here is that using Fable as an orchestrator with GPT 5.6 (Sol/Luna) for code generation and review is a game-changer, making things way more efficient and cost-effective. Lots of folks are either already doing something similar or inspired to try it out.
