> Why is that good advice? If that thing is eventually supposed to do the most tricky coding tasks, and already a year ago could have won a medal at the informatics olympics, then why wouldn't it eventually be able to tell if I'm using 2 or 4 spaces and format my code accordingly? Either it's going to change the world, then this is a trivial task, or it's all vaporware, then what are we even discussing..

This is the exact reason for the advice: The LLM already is able to follow coding conventions by just looking at the surrounding code which was already included in the context. So by adding your coding conventions to the claude.md, you are just using more context for no gain.

And another reason to not use an agent for linting/formatting(i.e. prompting to "format this code for me") is that dedicated linters/formatters are faster and only take maybe a single cent of electricity to run whereas using an LLM to do that job will cost multiple dollars if not more.

It's not that an agent doesn't know if you're using 2 or 4 spaces in your code; it comes down to:

- there are many ways to ensure your code is formatted correctly; that's what .editorconfig [1] is for.

- in a halfway serious project, incorrectly formatted code shouldn't reach the LLM in the first place

- tokens are relatively cheap but they're not free on a paid plan; why spend tokens on something linters and formatters can do deterministically and for free?

If you wanted Claude Code to handle linting automatically, you're better off taking that out of CLAUDE.md and creating a Skill [2].

> What? Why would that be a reasonable assumption/prediction for even near-term agent capabilities? Providing it with some kind of local memory to dump its learned-so-far state of the world shouldn't be too hard. Isn't it supposed to already be treated like a junior dev? All junior devs I'm working with remember what I told them 2 weeks ago. Surely a coding agent can eventually support that too.

It wasn't mentioned in the article, but Claude Code, for example, does save each chat session by default. You can come back to a project and type `claude --resume` and you'll get a list of past Claude Code sessions that you can pick up from where you left off.

That’s why they’re junior

The stateless nature of Claude code is what annoys me so much. Like it has to spend so much time doing repetitious bootstraps. And how much it “picks up and propagates” random shit it finds in some document it wrote. It will echo back something it wrote that “stood out” and I’ll forget where it got that and ask “find where you found that info so we can remove it.” And it will do so but somehow mysteriously pick it up again and it will be because of some git commit message or something. It’s like a tune stuck in its head or something only it’s sticky for LLMs not humans.

And that describes the issues I had with “automatic memories” features things like ChatGPT had. Turns out it is an awful judge of things to remember. Like it would make memories like “cruffle is trying to make pepper soup with chicken stock”! Which it would then parrot back to me at some point 4 months later and I’d be like “WTF I figured it out”. The “# remember this” is much more powerful because know how sticky this stuff gets and id rather have it over index on my own forceful memories than random shit it decided.

I dunno. All I’m saying is you are right. The future is in having these things do a better job of remembering. And I don’t know if LLMs are the right tool for that. Keyword search isn’t either though. And vector search might not be either—I think it suffers from the same kinds of “catchy tune attack” an LLM might.

Somebody will figure it out somehow.
