Okay those "hidden features" are amazing, especially the cross-session referencing. I hope we can look forward to that in the future

Also I definitely want a Claude Code spirit animal

jwilliams•1h ago

It's live! If you're on the latest cc you can use /buddy now.

Nevermark•50m ago

Ok! First prompt, obviously:

“Complete thyself.”

And I want an octopus. Who orchestrates octopuses.

jen729w•46m ago

It's a ridiculous folly. I've already lost a well-constructed question because I accidentally tabbed into my pointless 'buddy'.

(Yes, I know I can turn it off. I have.)

jruohonen•1h ago

Thanks, I'll use this for teaching next week (on what not to do). BashTool.ts :D But, in general, I guess it just shows yet again that the emperor has no clothes.

cool Archaeologization Collection Output

mdavid626•1h ago

How the hell is it 500k lines?

twsted•1h ago

It is vibe coded.

jatins•1h ago

There's this weird thing about AI generated content where it has the perfect presentation but conveys very little.

For example the whole animation on this website, what does it say beyond that you make a request to backend and get a response that may have some tool call?

siva7•1h ago

Really Weird but then it's so easy spot AI text by this pattern

Also it's just randomly incorrect in places. For instance, it lists "fox" as one of the "Buddy" species, but that's not in the code.

autocracy101•32m ago

That's been corrected, I did another fact checking pass!

autocracy101•34m ago

That's fair. The site isn't meant to be a deep technical dive, it's more of a visual high-level guide of what I've curated while exploring the codebase while assisted by AI, 500k loc codebase is just too much to sift through in a short amount of time.

Nice site. I might suggest moving SendMessage to the Hidden Features as they don't appear to have implemented a ReadMessage or ListMessages tools.

stingraycharles•50m ago

I guess they really do eat their own dogfood and vibe code their way through it without care for technical debt? In a way, it’s a good challenge, but it’s fairly painful to watch the current state of the project (which is about a year old now, so it should be in prime shape).

Boris Cherny, the creator of Claude Code said he uses CC to build CC.

I expect dozens more "research articles" that

- find nothing - still manage to fill entire lages - somehow have a similar structure - are boring as fuck

At least this one is 3/4, the previous one had BINGO.

jen729w•48m ago

Is it just me or do I not find the Claude Code application that fascinating?

I use it all day and love it. Don't get me wrong. But it's a terminal-based app that talks to an LLM and calls local functions. Ooookay…

j45•43m ago

Clever architecture often can still beat clever programming.

parasti•35m ago

I feel the same way. Given it's AI-written, looking at the code isn't even worth it to me. I would rather read a blog post about how they develop it day to day.

vivzkestrel•45m ago

would be nice if the transformers code for one of these frontier LLM models got leaked, HN will have a field day with a reveal like that

loveparade•38m ago

I doubt there is anything special about the transformer code the frontier labs use. The only thing proprietary in it are probably the infrastructure-specific optimizations for very large scale distributed training and some GPU kernel tricks. The real moat is the training data, especially the RLHF/finetuning data and verifiable reward environments, and the GPU clusters of course.

The open source models are quite close, and they'd probably be just as good with the equivalent amount of compute/data the frontier labs have access to.

Feel free to add this to Awesome Claude code. https://github.com/rosaboyle/awesome-cc-oss

lastdong•37m ago

I hope /Buddy is ported across to OpenCode.

m132•27m ago

I mean, I get it: vibe-coded software deserves vibe-coded coverage. But I would at least appreciate it if the main part of it, the animation, went at a speed that at least makes it possible to follow along and didn't glitch out with elements randomly disappearing in Firefox...

How is this on the front page?

sibtain1997•27m ago

Kairos and auto-dream are more interesting than anything in the agent loop section. Memory consolidation between sessions is the actual unsolved problem. The rest is just plumbing tbh

rhofield•13m ago

Really nice visualisation of this, makes understanding the flow at a high levle pretty clear. Also the tool system and command catalog, particularly the gated ones are super interesting.
