Anthropic's Claude Code's full source code leaked.

Anthropic's Claude Code's full source code leaked. Claude is seen by many to be the best coding LLM on the market with Anthropic proudly stating that Claude Code itself is mostly written by the LLM.
Now this sounds good as long as nobody can see the code which is quite the trash fire. Detecting "code sentiment" via regular expressions, variable and functions names containing prompt parts trying to influence the bot, a completely intransparent mess of a control flow that makes actual maintenance and debugging functionally impossible and the prompts ... of the prompts. All the begging and pleading to the chatbot not to do this or not to do that or please to do this.
It is fascinating but it is as far away from actual engineering as drunkenly pissing your name in the snow. Dunno what you call the people prompting software at Anthropic but "engineer" is not it.
Now it is fun to look at the currently hyped product striped bare and showing its pathetic quality but that is the future of software if we let those companies continue to undermine every good practice software engineering has tried establishing.
The software we have to use will be bad, insecure, unmaintainable, expensive with nobody having the skills or resources to build something better. As I wrote a few months ago: LLM based software production is equivalent to saying that fast fashion should be the only way to produce clothing. A tragic degeneration of the quality of the artefacts we rely on build for maximum profit on the backs of people in countries from the global majority.

I love this so very much I could cry. -

@tante great timing only a couple of months before the plannend IPO of Anthropic.

@tante I often wonder how much of (especially proprietary) software already suffered from these issues before the whole LLM situation came about.
This Reddit thread is a good example. A dev posts some visible problems with the leaked code — some problems more serious than others, but just about everything in there counts as dubious “code smell”, sketchy team/organization culture, or both, at a minimum.
The general response? Blowing it off. Stating that the person posting this doesn’t know what real software development is like. Reinforced by an AI-generated summary at the top of the thread, emphasizing the sentiment just described, and generally belittling the concerns raised here.
(TL;DR summary of my own experience with enterprise software development, going back almost 30 years: the quality of what’s in the Claude Code leak is, at the absolute best, definitely on the “very dysfunctional” side of “typical”. I’ve seen lots of dubious code, outdated code, tech debt time bombs as code, and just plain crap code; I have *not* routinely seen codebases for major applications that look quite like this.)

@tante I know devs that are saying if AI makes them 10-20% more productive it is worth it. And there’s a rejection of the ethical implications of the technology. I’m thankful I’m on the tail end of my career.

@tante but it's the AI Overlord god code it's not meant to be understood by meat sacks ...

@tante might well be the event that will make the bubble-popping begin. especially because its so far away from the values that anthropic tries so hard to project.

@tante Ever since the Industrial Revolution, capitalism has been thriving on producing bad quality for cheap, and then selling that cheap disposable shit to everyone so they have to throw it out and replace it when it breaks. Before the Industrial Revolution, people didn't have many pieces of clothing, but their clothes lasted for decades. Then mechanical looms produced so much cloth for so cheap that weavers lost their livelihoods, even though their artisanal cloth was far superior. All of a sudden, many people could afford to buy a lot of new clothes, but then they had to keep buying them because the fabric didn't last as long as it used to.
Making things cheap, shoddy, disposable, has always been the general direction of industrial mass production. If it's cheap enough, who cares if it breaks after a while, just buy a new one.
First it was textiles. Then it was all kinds of consumer goods. After WW2, everything became increasingly disposable. Nowadays even entire washing machines are often made out of plastic so that they break after a decade. Automated factories don't care if their products are of worse quality than the things that came before, they just dump their cheap shit onto the marketplace until the competition crumbles.

@angiebaby @tante my understanding was the the code was leaked and then quickly reimplemented in another language using Claude Code in order to thwart takedown requests.

@tante I wouldn't claim that I expected something else, but I sure hoped for it. So, at least the harness is known now to be iteratively developed to adress the symptoms. Looks like LLMs are too complex even for the "real" experts, compared to an eternal GenAI beginner like me. They just have more optimism about how much control they have.

@tante I am currently significantly refactoring a medium sized C++ code base from the 00s. I have mostly only used LLMs to suggest sed substitutions to me. I will probably rely more on traditional AST-based refactoring e.g. clang-tidy initially, though I have an item to turnup Opencode.ai. I do not trust Cursor, Codex, GitHub Copilot or Claude Code.
