Great to read your story is continue ( maybe sometime we can found the clue who is the killer ).
In this case I spend even a weeks ( or more ) for talking about a project, before ask to create a single line of code.
If I ower step the agents, for us also important that phase.

Hi Peter, That's sounds like a great approach in your projects! Cheers! 🙏🌹

This is so real. I have used AI in a language I did not know and everything looked correct until it broke in weird ways later 😅
Explaining first, then coding + using tests/race detector — that’s the part most people skip.

Hi Bhavin — yes, that "looked correct until it broke in weird ways" is exactly what has happened to me before too. The compiler says yes, the tests say yes, and then production says something completely different at 2am. Thanks for reading! ❤🙏🌹

curious what specific 'language' you mean here, is this about the internal prompt structure claude code uses to reason about tasks or something more like the way it interprets file context and tool calls differently than regular claude?

what specific 'language' you mean here

Hi Lin Uncut!

The language referred to is the particular coding language that is output by the AI. In our narrative article, it's Go. We're not referring to the AI prompt structure or Claude Code vs. Claude, but simply the output language.

What happens when you're experienced with a language like Python or JavaScript, and Claude Code gives you Go or Rust, based on the requirement? That's the point of this article.

Hope this helps. Cheers! ✨🙏❤

The insight about not being able to calibrate confidence in unfamiliar languages is spot on. I've caught myself nodding along at AI-generated Rust code that compiled fine but had lifetime issues I couldn't sense because I didn't have the instincts yet.

Hi klement — your Rust example is perfect. Compiles fine, ships fine, but breaks later.

Appreciate you putting a concrete example on it. That's the kind of comment that makes the article better. Cheers! 🙏✨

This was a really eye‑opening read! I hadn’t realized how much groundwork goes into making LLMs like Claude actually usable behind the scenes. The idea of treating model interactions with a structured “code” or protocol really highlights how AI systems are evolving beyond simple prompting into true developer ecosystems. Great breakdown!

Great article, definitely gives a lot to think about 🙂

The only concern I’d have is relying on AI tools as a single source of truth when learning new things. As we all know AI can make mistakes. When someone is new to a topic, they might not recognize those mistakes and memorize incorrect concepts. For example, once when generating SQL q&a for interview prep, I didn’t specify the vendor, and the AI mixed concepts from PostgreSQL, MySQL, etc., without mentioning it. What if that happens to someone who learns SQL?

BTW, adding episode number as “Episode 7” is a really nice touch! It enhances the sense of continuity in the series and helps the reader feel where they are 🙂

Hi Marina — Your SQL experience is a great example of working with an AI. Vendor-blending is exactly the kind of subtle error that an AI can sometimes produce.

And glad the episode numbering helps! Thanks and cheers! ❤✨🙏

That was Brilliant, Aaron. Thanks
This was, what i have been questioning for so long
I was so distant to the idea of vibecoding (though i am not a fan of this terminology, it felt right now) when one does not know that specific language.
And this post not only justified my concerns but also provided some solid strategy to mitigate the risk.
I was thinking that one should know the language in which she is making LLM code for her... But was not sure how to make it fast and in the most reliable way. I would possible open the docs and go thru it + do some easy tutorials (ok frankly, i will probably do that still but next to the strategies here :) )

cheers
