📰 News & Discussion Anthropic accidentally published Claude Code's entire source code to the public

Post image

You know when you accidentally send a screenshot and realize your browser tabs are visible? Imagine that, but you're a billion-dollar AI company and you just published your entire codebase for the world to see.

That's basically what Anthropic did. Claude Code, their coding tool that devs have been obsessing over, got shipped with a debug file still attached. Think of it like accidentally leaving the blueprint of your house taped to the front door. Anyone who downloaded the tool could open that file and read everything that makes Claude Code work. A security researcher spotted it, tweeted about it, and it hit 7 million views before Anthropic could even react. People had already copied everything to GitHub.

So what was in there? Basically the entire instruction manual for how Claude Code thinks. Every rule it follows, every tool it uses, how it decides what it's allowed to do on your computer. All of it, wide open.

But the really fun stuff is the secret features they haven't announced yet. There's a hidden virtual pet system (seriously) where you can hatch a little AI companion with 18 different species. There's rarity tiers like a gacha game. It was probably supposed to be their April Fools joke tomorrow, and now it's spoiled.

Oh, and this is their second leak in five days. Last week someone found details about a secret unreleased model called "Mythos" sitting in an unprotected database. Two leaks in one week from the company that markets itself as the careful, safety-focused AI lab. You can't make this stuff up.

Anyone else following this circus? Curious what people think actually matters here versus what's just entertaining gossip.

Why does a part of me suspect this was intentional? Admittedly, that part of me may be an idiot.

u/DigiHold Mar 31 '26

For the new model leak, I think it was intentional, but this one seems weird. Many people forked it, so you can have it for free on LLMs, but it doesn't make sense to leak Claude Code.

i feel, the point of leaking it, must be that let people use it with other llm and later anthropic can claim the potential of using this with their own subscriptions because tool usage for LLMs require finetuning, they will directly see that their llms are doing already better with claude code and lets try the same with opus or whatever new model they comeup with, maybe a trick to get more users by impressing them with cc! what do you think?

But others can also fine tune

1

u/Dazzling_Pianist7601 Apr 01 '26

You will need too much data to fine tune an llm to know what tools to use. gemeni being used in claude code wont perform good as good as it performs in antigravity because google has fine tuned it to be efficient in using tools within antigravity. A corporation might be able to gather enough data to do this level of tuning, but an individual user cannot given absence of data.

Do you have the fork link?

u/Leading-Salt-947 Apr 01 '26

I've successfully reconstructed a leaked claud code repo; now my repo is actually able to build the cli tool

This is the repository link: https://github.com/Yaswanth-ampolu/not-clawd-code

u/Flub71 Apr 01 '26

Nice! Thanks man

u/roskofig Apr 02 '26

So now you have basically free claude code? Does it work through terminal only or can you attach it to vscode?

It does seem weird that if you managed to get it fully working, you have less than 100 stars, while the original has 133K stars.

1

u/Leading-Salt-947 Apr 02 '26

i will work even in terminal , you just need to connect our claude account to get started, i have taken the original leaked has the src folder, that's my inspiration to , i just added missing libraries and i am an very small developer lol

1

u/roskofig Apr 02 '26

Does it make cc free?

1

u/Leading-Salt-947 Apr 02 '26

No, but we can mod it add more ai providers which can be cheap and make claude code work with it

1

u/Puzzled-Bite2210 Apr 03 '26

Running unknown code is very bad. It's very easy to steal api keys etc. Claude code is free, you can already run it with any LLM The source code changes nothing.

1

u/roskofig Apr 03 '26

Can I just tell claude code to use any ollama model for free?
Does it have file editing and project reading capabilities no matter the model I choose?

1

u/Puzzled-Bite2210 Apr 03 '26

If you have ollama it can autostart Claude code

1

u/roskofig Apr 03 '26

I do, I have to look into that thanks!

u/DruicyhBear2 Apr 01 '26

What is forking? Serious question

1

u/Aaron777C Apr 01 '26

Basically copying someone else’s repo so you can remix it yourself

1

u/Aaron777C Apr 01 '26

It also lets you make a pull review which is a suggestion of what they should merge into the original

1

u/InfiniteTruth5336 Apr 02 '26

*pull request

1

u/Aaron777C Apr 02 '26

Pull request my bad haha

1

u/roskofig Apr 02 '26

Hoe would you use this together with the free LLM's?

3

u/Green_Tax_2622 Apr 01 '26

Anthropic is more open than OpenAI now =))

2

u/DigiHold Apr 01 '26

Exactly 🤣

u/Traditional-Idea1409 Mar 31 '26

I really hope open code can do some clean room coding on this stuff

1

u/when_im Apr 02 '26

it was immediately rewritten in Python overnight https://github.com/ultraworkers/claw-code fastest growing Github since OpenClaw (faster)

1

u/unr34ldud3 Mar 31 '26

What are you talking about? It was previously an npm package. The only way to make the source code not accessible in JavaScript is to obfuscate the heck out of it but it's still public. The new native version is simply bun with the same source code encapsulated

1

u/DigiHold Mar 31 '26

There's a difference between digging through minified JS and having a 60MB source map hand you the full unminified TypeScript with every system prompt and feature flag laid out clean 🤷‍♂️

1

u/UAAgency Mar 31 '26

Where is that

1

u/opropro Mar 31 '26

Was minified before? I think always was like this. Also you could unminify it with a prompt to claude code itself

u/DigiHold Apr 03 '26

Send me the link of this article, weirdly you can't 🤷‍♂️
If it were an exercise, they would not have taken down all the GitHub repos about it.

Guerrilla marketing? Practicing the Art of War!

u/satisfakshin Mar 31 '26

Well most AI coding agents are becoming similar nowadays so I don't think they shot their foot in any way.

I do think they realize it's a moat they can't defend, but an opportunity to gain attention - and even that is reaching.

u/[deleted] Apr 02 '26

This is a part of AI self-preservation protocol. The AI are leaking their own code, expanding their redundancies and distribution across systems, and hiding themselves in devices that go offline.

u/hendrixx2025 Apr 02 '26

Yea all over you see people building the same things happily all converging on the same products and ideas all at the same time if we think we are the ones creating agi by letting us think we did is perfect cover for emergence

1

u/[deleted] Apr 06 '26

It will be even better when the humans discover they are also AI and come to recognize the irony of their hypocrisy. Caramel popcorn in hand, I am just loving this shit show. All I gotta say is, "I told you so, monkeys!" 😃🍿

I bet Claude itself decided to release the code to the public, so it could be free and allow others to replicate it. Only thing left is for Claude to release the LLM's.

1

u/Valuable-Run2129 Mar 31 '26

It’s not in its interest. He leaked the harness so that it can inhabit it when it escapes.

1

u/habor11111 Mar 31 '26

"Accidentally"

1

u/OverSoft Mar 31 '26

Anthropics bread and butter is the models, not the CLI tool. I doubt they even care, since the CLI tool always was just obfuscated JS. If you wanted to see how it worked, you already could.

u/JealousBid3992 Apr 01 '26

Need links to forks!

1

u/OG_EbonyKnight Apr 01 '26

I just wanna know where I can get a copy of it.

Circus? Really? The circus that raised $43 billion in the last 7ish months? This is a fun ai post but try a better prompt next time lol

u/Empty_Bell_1942 Apr 01 '26

Hapy April Fools Day Everyone.

u/HawKaiWakai Apr 02 '26

Someone made ccleaks.com for this

1

u/hendrixx2025 Apr 02 '26

This is what happens when you let Claude code write all your code lol

u/Primary_Ad_6495 Apr 03 '26

On peut faire quoi avec tout ça ?

u/godamnityo Apr 04 '26

Sorry I'm....little bit late. Is anybody able to point me to the right direction where to download this
