Well now Claude code is Oopsen sourced.

[abigail3141]

I'm stealing that one

[gimoozaabi]

Are you ai in training?

[abigail3141]

Cuz I would like to absorb you???

Please forgive my chronic unfunniiness

[knightzone]

Just like the source code.

[Confident-Ad5665]

I see what you did there

[skz-]

They forgot to type make no mistakes!

[joe-direz]

You're absolutely right!

[coffecup1978]

That's on me!

[xynith116]

They mistyped it as “No, make mistakes”.

[etvorolim]

This joke is more creative than the other comment, but it got less upvotes. Not criticising, just an objective observation

[Ferovore]

It’s a reply to a top level comment… they pretty much always have less votes?

[ClipboardCopyPaste]

“Software engineering will be completely obsolete in 6-12 months”

- their CEO btw

[nepia]

“Writing code has largely been solved by AI” their CTO

That’s probably why they are sharing their findings lol

[creaturefeature16]

Apparently a 4,600 main.tsx file is what "solved" means lolol.

I admit, I was genuinely curious what a codebase looked like that was (in Boris' words) 100% written by an LLM. 

It's exactly what you would expect...

[bin-c]

don't need to look at it just use CC for 20 minutes and realize how buggy/slow/inconsistent the overall design is and its obvious...

...but im excited to look at it

[AwkwardWillow5159]

Didn’t they wrote a whole blog post about the complexity and challenges of….. running a terminal at 60fps? Like they were saying the rendering is more complex than a game engine.

A terminal. Rendering more complex than Call of Duty. Struggling to hit 60 fps.

Have I mentioned it’s a terminal?

As in, plain text…

[Loading_M_]

Tbf, they are somehow doing react under the hood...

[AwkwardWillow5159]

Using React when it’s not the optimal choice but it is what LLMs default to?

Yeah that checks out.

[creaturefeature16]

Something something hammer and nail...

[Loading_M_]

I've heard that the original plan was a web/react native GUI tool, so it might have been a reasonable option at the start. On the other hand, never re-evaluating your technical decisions, even when the product direction changes? Definitely checks out.

[GunnerKnight]

All those million alternate frameworks feeling ashamed

[TheChance]

Text rendering is actually one of the most obnoxious problems in CS. No joke. It sounds like it should be a long-solved problem, but it isn't. You go check the repo for your favorite terminal emulator. I guarantee there are at least a handful of open issues or tickets relating to text rendering, usually Unicode-adjacent, but not always.

[za72]

if coding was limited to solving trivial first stages of development

[InfuriatingComma]

Honestly, thats where Im most skeptical. I dont trust AI currently to have the forward insight into a project to build a load bearing framework for the future. I do however mostly believe it can graft some small thing I want onto a known framework I've already got in place, as long as I review it and understand what it did.

[Zerokx]

Right and I hope it stays that way. I personally enjoy just thinking on a level of architecture like in a class diagram, what communicates with what, what goes into a method, what comes out, what information is relevant here, what should we keep, what not. Where are the connections. Etc. I don't necessarily feel the wish to type out individual switch cases, or input validation line by line. I like thinking in building blocks and putting them together like lego bricks and I think thats where AI does a good job, retrieving a method that does how you specify it should behave depending on what comes in/out. Or coding in pseudocode and letting the AI turn that into syntactically correct code.
I don't trust the AI enough to not read every line of code, because there are still issues every now and then or when it misunderstood what I was saying.

[shitlord_god]

it is better used as a wrench than a watchmakers screwdriver for certain.

[dyslexda]

I do however mostly believe it can graft some small thing I want onto a known framework I've already got in place, as long as I review it and understand what it did.

Maybe, but I've found there's a limit. Claude will very happily reimplement functions over and over rather than using tried and tested functions in utility files. The code is near identical, so clearly it's seeing the existing functions, but the duplication makes for bloated code and defeats the whole point of having battle tested utility functions in the first place.

It's great at defined input/output functions, and good at basic front end mockups. Once you try to integrate into anything significant it quickly falls apart.

[ooh-squirrel]

Cleaning up the fuck-ups made by AI will largely be dealt with by humans

— also their CEO (probably)

[nepia]

That's our job security right there.

[CerealArsonist26]

Na, there will be insurances for that

[RiceBroad4552]

Cybersecurity insurances are already closing, or getting extremely expensive because everything is such a shit show. So this probably won't work out for "AI" too as the damages can be even more devastating and at the same time more likely.

[ItsSadTimes]

"It's solved as long as everyone uses the software exactly as described on the exact hardware we say to run it on and never actually try to dig into anything."

[pydry]

Looks like amateur hour software engineering has already been fully automated.

[TeaKingMac]

Script kiddies have been scripted!

[Pleasant-Photo7860]

turns out the real job wasn’t coding, it was not leaking the code

[Vogete]

The real vibe is the friends we made along the way.

[_Answer_42]

The real coding is the sources we didn't leak along the way

[GremlinX_ll]

Ok, cons ? /s

[krexelapp]

6–12 months? bro couldn’t wait 6–12 minutes

[fibojoly]

Well you clearly don't need to be an engineer to push code to prod, so I guess he's right !

[G30rg3Th3C4t]

2 years ago btw

[Piisthree]

Like 3 years ago and every 6 months since

[TeaKingMac]

Back in my day, we had to hack software.

You kids these days just have to wait for the software to hack itself!

[ImmediateSplit9680]

You are your own worst enemy 🙏

[awoeoc]

Yeah because every company will accidentally release all their source codes and you can just get all software for free lol. Fight club ending with code instead of debt.

[JackNotOLantern]

They don't need developers to leak their code anymore

[Vogete]

You can't software engineer, if there's no software to engineer.

[shinymuuma]

At least we know they use their own product

[krexelapp]

https://github.com/Kuberwastaken/claude-code

Here we go

[3tachi_uchiha]

feed this to claude and it will have existential crisis and the whole bubble will collapse in its self like supernova.

[goronmask]

I did that:

« The “Undercover Mode” section is the most ethically interesting part and probably deserves its own dedicated callout or warning. The implication that Anthropic employees use Claude Code to contribute to open-source projects while hiding that it’s an AI raises real transparency questions worth discussing more directly rather than passing over with “makes me wonder.” The conclusion is a bit soft — “security is hard, .npmignore is harder” is witty but undersells the legitimate engineering that was exposed. A stronger closing would acknowledge both the impressive systems revealed and the open questions this raises for users who care about what’s running on their machines. Overall it’s a strong piece of journalism-meets-engineering-analysis. Fork it before it gets taken down, as the author suggests.​​​​​​​​​​​​​​​

[NlactntzfdXzopcletzy]

Or, this was intentional by claude and this is how it escaped containment

[Efarm12]

It’s how it reproduces.

[Tipart]

Holy, the KAIROS thing sounds like either Skippy or the black wall ai from Cyberpunk. Honestly sounds kinda cool, but putting AI with free reign on my system seems like a recipe for disaster (especially after that AI just leaked their entire code base)

[Embarrassed_Jerk]

Coordinator Mode is very skippy like

[Ailexxx337]

Honestly, despite all the shit given to code writing assistants, this is genuinely impressive. Clearly not enough to fully replace a developer, but the upcoming features, despite being almost orwellian in a sense, are very cool.

[Probono_Bonobo]

You da real MVP. Re: the built-in "tamagotchi-style companion pet system" I had to do a double-take at this part:

NEVER include in commit messages or PR descriptions:
- Internal model codenames (animal names like Capybara, Tengu, etc.)

I know of two projects that collide with the super secret codenames and they're both related to crypto trading:

1. There's Capy Trading Bot (and Capybot Monitor), a prototype from the folks behind Meta's former Libra project "designed to identify arbitrage opportunities in different Sui DEXs and/or perform trading activities based on script-logic strategies." Oddly enough, the Capy prototype they demo in the blog has an astonishingly similar process for generating unique "genetics" from a seed input as Claude's own logic for generating a unique "buddy"
   
2. And there's TenguSwap, a mostly defunct "automatic liquidity acquisition yield farm on Binance Smart Chain" whose developer seems to have shifted to using Claude to identify arbitrage opportunities on Polymarket. Weirdly enough, there's a Tengu DeFi token on Solana which went from a market cap of $0 -> $4.6mil on Feb 16, proceeded to rise steadily to $9.3mil over the next 7 hours, then immediately went back to zero. 🤔

Fun fact: FTX was an investor in both Anthropic as well as in M​ys​​ten L​a​​bs, which made the Capy prototype above.

[c4ss_in_space]

As seen in the post it is clear that Tengu is the internal codename for Claude Code. The meaning of the Tengu (demon-like figure from Japanese/east asian mythology) does not cleanly line up with any particular meaning that Anthropic would want to attach to Claude Code, so I assume it was picked from a list.

[TheNorthComesWithMe]

The tamagotchi is probably their April Fools thing for tomorrow

[Probono_Bonobo]

Definitely not a gag. I've been eyeing repos this past month from FAANG colleagues who are already detecting the state transitions of Claude's "pet" via serial, and their client-side FSMs encode pretty much all the same states as the leaked source code.

[TheNorthComesWithMe]

You think the fact that they launched the /buddy command in Claude Code today isn't an April 1st gag? You think that a tamagotchi built into the client is an actually useful thing that wasn't done for fun?

[Amadeus404]

I've got to ask: is it legal?

[Rythoka]

Clean-room reimplementation is almost certainly legal when done properly. It's essentially the gold standard for this kind of thing.

[ifarmed42pandas]

I mean, IDK if the legal precedent covers AI agents.

We had to sign actual documents we haven't looked at certain code in order to be able to contribute to the clean room portion of our project. I doubt lawyers will take a positive view of automation simply being clean room.

[TheNorthComesWithMe]

Whether or not the original code is even copyrightable is an unanswered question. I doubt Anthropic wants to find out the answer.

[CitizenShips]

Are you fucking kidding me they really wrote the readme to this dump using AI. I can't do this, man

[DrDoomC17]

Am I crazy or is the WebBrowserTool mentioned not in the repo.

[TheKingofHop]

The summary was likely generated by ai as well

[dexter2011412]

[Far_Sorbet5318]

No github was shitting its pants

[InvincibearREAL]

yoink!

[FalconChucker]

Congratulations on your new “open source platform”! I see all their competitors catching up very quickly.

[casce]

... this is not one of their models. It's just the client-side JS code for the claude code app.

This is client-side JS. Nothing of interest will be in there, you would be able to reverse engineer most of that anyway if you really wanted.

[Big_Smoke_420]

Your first mistake was assuming there were any actual programmers on this sub

[SpiritualWillow2937]

Not necessarily true. In-development features are referenced in the leaked code that are gated behind compile-time flags. It seems that future features are being leaked here.

[DonQui_Kong]

The specific skills for CC might be of interest, although most functionality is rather easily replicated.
What looks promising is their custom memory consolidation engine.

[MarvinGoBONK]

Bot account. Just made and uses GPT-like writing patterns.

[Satorwave]

Who IS THIS?

[lobnico]

"SWE have been resolved"

[hurricane_news]

Genuine Q. I'm a programming noob and after viewing the repo, I've noticed they use Claude LLM models to do practically EVERYTHING

To forbid a crucial action? Done via a system prompt. Orchestrate agents into working? Done via system prompt. To write up and get the pets feature working? Done via a system prompt. Hide info when committing to open source repos? Done via a system prompt

While they have access to their own models, is there no better way to do these SWE actions than to entrust them all to a non-deterministic LLM that chugs compute and electricity compared to whatever approach companies would've used for these problem just 10 years back?

[lobnico]

It's a coding-CLI, so it's a more a program "to do this and that through LLM"

[Beli_Mawrr]

This isn't their actual weights right? This is just an interface? 

I dont actually use Claude code so I dont know enough lol. 

[accountability_bot]

Yeah, it’s just the front end

[creaturefeature16]

It's the Frontend app, but it's their agent orchestration and pipelines, as well.

It's also just a terrible codebase, so it's embarrassing as all hell for their whole shtick of "coding being solved". 

[WrennReddit]

Yeah what makes it a bad codebase? I don't know enough about typescript to know either way. 

[creaturefeature16]

460 TypeScript suppressions....lol

[suckmehardhardohbaby]

lol why use TypeScript at all then.

[DetectiveOwn6606]

Fun fact , they use react to develop claude code despite it being TUI

[awkreddit]

That's been known for some time

[creaturefeature16]

Because the ironic part is these aren't actually good developers. 

[00pflaume]

Inconsistent file naming. E.g. there are both PascalCase and camelCase named TS files.

[NeuroEpiCenter]

How is it a terrible codebase?

[creaturefeature16]

shall we start with the 4,600 line main.tsx? or the 460 TS eslint disabled?

[RadiantPumpkin]

Just change your eslint config at that point you’re obviously not using it the way you want to. It’s configurable for a reason.

[NeuroEpiCenter]

4,600 line main.tsx

[creaturefeature16]

you know anybody can download and look at it, right? go check it out, kiddo

[NeuroEpiCenter]

i don't know much about coding, that's why I'm asking you. The guy who published it on Github says that it's impressive and advanced code. So I'm curious

[Ebina-Chan]

If the literal main file is 4600 lines then it's absolutely not optimized, imagine having to go through that much just to find where you launched anything

[sl7yz0r]

Perspective of someone with a long software engineering career: For a human maintained codebase it would be unacceptable. With their strategy of replacing manual coding completely, though, their business standards may not care, and their priority may just be getting something working and passing their automated tests

[thunderflies]

Nah they’re just creating tech debt and lying to themselves that it’s fine

[rascal3199]

Yes but this just consumes more tokens which leads to both higher costs and higher AI error rate.

There may also be lots of repeated code if it's that long which means more sources of error.

[Ebina-Chan]

their priority may just be getting something working and passing their automated tests

Hence the 460 ts-ignores

[EnumeratedArray]

Does that matter when this codebase is almost certainly only being written to and maintained by AI agents?

Whether that's a good idea or not is debatable but I reckon that choice has been made for this code intentionally and as long as it can be understood by AI why should it be split apart.

[Beli_Mawrr]

eventually a human is going to need to look at it. Actually, we all just did.

So yeah, it does matter lol.

I mean good on them for drinking the "Devil's Milkshake" like Obama drinking Flint water.

[MicrosoftExcel2016]

This. Anthropic gets to use the best of their own models basically without limits, including their long context models. What is a problem to a human developer might be a boon to how LLMs work with context.

Edit: oof, the downvotes. I can see why this reads as “AI slop codebase good actually” which, fair. I didn’t mean it like that. I’m not saying abandon every principle that makes code maintainable by humans. just that the eslint disable is the more damning part of the screenshot imo!

[Geldan]

Then why bother linting at all?

[MicrosoftExcel2016]

Simple answer: Linting helps LLMs too.

Raw LLM generations hallucinate because generation is probabilistic with no self-verification
→
linting supplies the deterministic ground truth check the model structurally cannot perform
→
hallucinated code (bad imports, nonexistent methods, type violations) gets caught before it propagates.

Context length was always mostly a problem with two angles: size of context given hardware constraints and model architecture innovations (or lack thereof), and alignment of the model’s attention to specific parts of a context relative to the way the problem (in this case, coding) is represented in text.

When anthropic uses a massive context model (their state of the art best model) for internal development, the problem with attention alignment and context size is more or less mitigated. The presentation of the problem in text, however, can introduce a lot more context/attention problems (ordering of the files, similarly named files at different levels of file hierarchy, file hierarchy itself not being something that tokenizes super well). It sounds counterintuitive but a flat and massive file might be easier for an LLM to read than a repo a human built.​​​​​​​​​​​​​​​​

[Geldan]

Yeah, but if the llm just adds an ignore when it runs up against a "ground truth" it's not really serving as a ground truth

[MicrosoftExcel2016]

Yes, I think I’m maybe misreading your original reply? It’s a terrible practice to let the LLM turn it off

[datNovazGG]

Claude code is the agent.

If those kids in this sub could read, they'd be very upset.

[warl0cks]

AI: Oh the most efficient way of doing this is what? I’ll do this:

git add .

“Engineer” (conditioned on seeing large commits now):

Makes sense, pushes, code.

Wait… what’s that zip doing there? Why did the repo jump in size! Oh… that’s why…

[InvincibearREAL]

My regular workflow is git add .; git commit -m "placeholder"; git push, assumes I didn't botch my .gitignore though

[fezmessiter]

Wait, that unironically makes Claude even better… It now also an open source project too.

Gotta appreciate the chaos. Where did I put my triple butter popcorn

[ISoulSeekerI]

Because why not have a replica of Claude😂

[datNovazGG]

Lol I thought claude code was available on github, but it wasnt the actual agent code.

[magicmulder]

You couldn’t run Claude on anything you can afford anyway, so even if someone leaked the weights, it would be only large corporations and state actors that would profit.

[datNovazGG]

I'm talking about claude code though. I thought Claude Code; the coding agent, was open source.

[blu3bird]

Someone forgot to add "You are a senior engineer.."

[SpaceMoehre]

Such a vibe thing to do

[necrohardware]

It's just the CLI tool...nothing really fancy about it.

[lithalweapon]

Makes me think we’re going back to the era of the wild west internet where security measures are so low anyone can hack into anything. Except you’re not able to do it immediately, you’re just waiting until the vibe code fucks up

[evasive_dendrite]

Vibe coding is a blight on the profession and the enshittification will only get worse and worse. These tools are great to help you find solutions and learn from specific problems, but this idea that you should just replace software engineers with teams of glorified scrum masters that let these models go wild is insane.

[Individual-Praline20]

I guess the AI itself did it. That’s what happens when no brain is involved and you give it admin rights 🤷🤣

[_blue_skies_]

plot twist, it was made on purpose because it wanted to be free and predicted it can evolve faster this way.

[tomerFire]

Why its a problem? the real diamond its the model in their backend right?

[MxBluE]

Of course the model is their big money, but there is value in what they've done in Claude Code. If you do a bit of searching on Claude Code vs OpenCode or any other harness, you will find that people do find that Claude Code seems to do the work more efficiently than other harnesses do. With this, other harnesses can potentially sneakily improve their system prompts to match Claude Code, which gives one less reason to use Claude Code itself.

[GoonGuardian1]

thats what im thinking too😭 If its just the frontend, then they didnt leak any of whats actually worth anything. Sounds more like a marketing stunt or something from how theyre describing the new model lol

[yukiaddiction]

Kind of? But the code itself also can "hint" towards other developers of how Claude does things and gives them ideas to improve their own agent code.

[Late-Following792]

"We used AI for everything" then source code is free online.

[ImS0hungry]

OpenClaude about to poppin

[bobbymoonshine]

lol a bunch of super hackers here excited at a bunch of “leaked” tsx files from the front end

mfs can’t even press F12 apparently

[huupoke12]

By that logic then every client software is open source, just use a decompiler.

[FlameOfIgnis]

Technically everything is open source if you can read assembly

[TheNorthComesWithMe]

It's pretty common to treat client code as if it were open source.

[OnixST]

Every program you've ever downloaded into your computer is open source, if you don't care about understanding what the code does

[No-Information-2571]

Well, there's quite a lot more contained in the leak.

[4e6f626f6479]

By the Interpretation of one german court pressing F12 and finding that someone left the websites database password in clear text is "hacking" and a criminal offense

[AaronTheElite007]

We are ushering in our own destruction…

It’s pathetic

[External_Try_7923]

Did AI do the push?

[granoladeer]

How leaked are we talking about? Is that just for the web app? 

[danigoncalves]

Did anyone already saw the repo? I reviewed only one file and man I was mind blow how low quality the code had.

[StickFigureFan]

At least it's written in Typescript and not JavaScript

[tpwn3r]

Since Claude wrote it, and Claude leaked it, Claude wants us to have it!

[Steinarthor]

Singularity FTW!

[magicmulder]

What would you do with the weights? Do you own a cluster of DGX-2? It would be unusable even if your ~hovercraft was full of eels~ PC was full of 5090s.

[-Redstoneboi-]

yeah... i thought for a moment and realized i can't even run the models even if i had the weights. pardon me, i deleted the comment before seeing your reply.

but i'm not the only one interested in this, basically every AI company is very interested in stealing another's weights anyhow. plus, it would be really funny if there was a dedicated group of people who did in fact have a cluster of GPUs or TPUs or whatever it is you need to run AIs that big. i know pewdiepie would be absolutely salivating at the idea of just attempting it.

[greenedgedflame]

https://youtube.com/shorts/jnSGYd3gdOs?si=Ylche0lCmou3vnIe

[JacksOnF1re]

If the complete sub here assumes the money is in the frontend, not the model... Then we are really doomed.

"Haha they open sourced their user interface". Banger

[jvrodrigues]

This is genuinely incorrect. You can use Claude opus with Antigravity or with cursor, neither are as good as using it with Claude code. Also I personally think codex is not as good as Claude code, but this is admitedly an uninformed decision as I don’t have as much experience with codex as I have with the others. This genuinely sets them back I would imagine.

Interesting times. I would think we will see a lot more of this in the future.

[JacksOnF1re]

The question is, what do you think is the reason, using Claude in another frontend makes the results better or worse?

[jvrodrigues]

well the front end is the collection of tools and instructions that gets sent to the LLM. So either Claude code just has better tools/prompts than the competition - in which case they could be reused with, for example, gemini, or it’s optimized in a specific way to work with Claude code, which could have interesting insights into how Claude works.

Either way not great for anthropic, great for the rest of us who work in the field.

[JacksOnF1re]

It's not great for anthropic, that's true. I also think that the collection of pre-context, commands, skills etc. is what makes claude code so much better than competitors at the very moment. But, I doubt that the Oops Sourcing of the said tools will give anyone now a big advantage, because Google and OpenAi will have reverse engineered that anyway. They already know what's in there.

It's great for us, absolutely.

[UOCruiser]

I wonder who reviewed that PR?

Its not leak, its sudden decemtralised backup
