This is actually really cool. I just tried it out using an AI studio API key and was pretty impressed. One issue I noticed was that the output was a little too much "for dummies". Spending paragraphs to explain what an API is through restaurant analogies is a little unnecessary. And then followed up with more paragraphs on what GraphQL is. Every chapter seems to suffer from this. The generated documentation seems more suited for a slightly technical PM moreso than a software engineer. This can probably be mitigated by refining the prompt.

The prompt would also maybe be better if it encouraged variety in diagrams. For somethings, a flow chart would fit better than a sequence diagram (e.g., a durable state machine workflow written using AWS Step Functions).

Answers like this are sort of what makes me wonder what most engineers are smoking when they think AI isn’t valuable.

I don’t think the outright dismissal of AI is smart. (And, OP, I don’t mean to imply that you are doing that. I mean this generally.)

I also suspect people who level these criticisms have never really used a frontier LLM.

Feeding in a whole codebase that I’m familiar with, and hearing the LLM give good answers about its purpose and implementation from a completely cold read is very impressive.

Even if the LLM never writes a line of code - this is still valuable, because helping humans understand software faster means you can help humans write software faster.

    Many devs still think their job is to write code not build products their business needs. I use LLMs extensively and it’s helped me work better faster.

      LLMs excel at some things and work very poorly at others. People working on different problems have had different experiences, sometimes opposite ends of the spectrum.

        I think the people who claim 10x-100x productivity improvements are working on tasks where LLMs work really well. There is a lot of development work out there that is relatively simple CRUD and LLMs are very good at it. On the complete opposite end we have designing new algorithms/data structures or extending them in a novel way. Or implementing drivers for new hardware from incomplete specs. LLMs do not do well on these tasks or even slow down developers 10x.

        So, I think the claims of improvement in productivity and regression in productivity can be true at the same time (and it's not just that people who don't find using LLMs productive are just prompting them wrong).

        I think most can be gained by learning in which areas LLMs can give large productivity boosts and where it's better to avoid using them. Of course, this is a continuous process, given that LLMs are still getting better.

        Personally, I am quite happy with LLMs. They cannot replace me, but they can do a chunk of the boring/repetitive work (e.g. boilerplate), so as a result I can focus on the interesting problems. As long as we don't have human-like performance (and I don't feel like we are close yet), LLMs make programming more interesting.

        They are also a great learning aid. E.g., this morning I wanted to make a 3D model for something I needed, but I don't know OpenSCAD. I iteratively made the design with Claude. At some point the problem becomes too difficult for Claude, but with the code generated at that point, I have learned enough about OpenSCAD that I can fix the more difficult parts of the project. The project would have taken me a few hours (to learn the language, etc.), but now I was done in 30 minutes and learned some OpenSCAD in a pleasant way.

    Cold read ability for this particular tool is still an open question. As others have mentioned, a lot of the example tutorials are for very popular codebases that are probably well-represented in the language model's training data. I'm personally going to test it on my private, undocumented repos.

    IMHO, Ai text additions are generally not valuable and I assume, until proven wrong, that Ai text provides little to no value.

    I have seen so many startups fold after they made some ai product that on the surface level appeared impressive but provided no substantial value.

    Now, I will be impressed by the ai that can remove code without affecting the product.

      Current AIs can already do this decently. With the usual caveats about possible mistakes/oversight.

    I'll just wait for a winner to shake out and learn that one. I've gotten tired of trying AIs only to get slop.

    Summarization is one thing LLM's can do well, yes. (That's not what this current hype cycle is selling though.)

    > Answers like this are sort of what makes me wonder what most engineers are smoking when they think AI isn’t valuable.

    Honestly, I wonder if I'm living in some parallel universe, because my experience is that "most engineers" are far from that position. The reactions I'm seeing are either "AI is the future" or "I have serious objections to and/or problems with AI".

    If you're calling the latter group "the outright dismissal of AI", I would disagree. If I had to call it the outright dismissal of anything, it would be of AI hype.

    > I also suspect people who level these criticisms have never really used a frontier LLM.

    It's possible. At my workplace, we did a trial of an LLM-based bot that would generate summaries for our GitHub PRs. I have no idea whether it's a "frontier" LLM or not, but I came out of that trial equally impressed, disappointed, and terrified.

    Impressed, because its summaries got so many details right. I could immediately see the use for a tool like that: even when the PR author provides a summary of the PR, it's often hard to figure out where to start looking at the PR and in which order to go through changes. The bulleted list of changes from the bot's summary was incredibly useful, especially because it was almost always correct.

    Disappointed, because it would often get the most important thing wrong. For the very first PR that I made, it got the whole list of changes right, but the explanation of what the PR did was the opposite of the truth. I made a change to make certain behavior disabled by default and added an option to enable it for testing purposes, and the bot claimed that the behavior was impossible before this change and the PR made it possible if you used this option.

    Terrified, because I can see how alluring it is for people to think that they can replace critical thinking with AI. Maybe it's my borderline burnout speaking, but I can easily imagine the future where the pressure from above to be more "efficient" and to reduce costs brings us to the point where we start trusting faulty AI and the small mistakes start accumulating to the point where great damage is done to millions of people.

    > Even if the LLM never writes a line of code - this is still valuable, because helping humans understand software faster means you can help humans write software faster.

    I have my doubts about this. Yes, if we get an AI that is reliable and doesn't make these mistakes, it can help us understand software faster, as long as we're willing to make the effort to actually understand it, rather than delegating to the AI's understanding.

    What I mean by that is that there are different levels of understanding. How deep do you dive before you decide it's "deep enough" and trust what the AI said? This is even more important if you start also using the AI to write the code and not just read it. Now you have even less motivation to understand the code, because you don't have to learn something that you will use to write your own code.

    I'll keep learning how to use LLMs, because it's necessary, but I'm very worried about what we seem to want from them. I can't think of any previous technological advance that aimed to replace human critical thinking and creativity. Why are we even pursuing efficiency if it isn't to give us more time and freedom to be creative?

      The value is that it got the details correct as you admit. That alone is worth the price of admission. Even if I need to rewrite or edit parts it has saved me time, and has raised the quality of PRs being submitted across the board. The key point with these tools is *Accountability*. As an engineer you are still accountable for your work. Using any tool doesn't take that away. If the PR tool gets it wrong, and you still submit it, that on the engineer. If you have a culture of accountability, then there is nothing to be terrified of. Any by the way the most recent tools are really, really good at PRs and commit messages.

        Are you accountable for CPU bugs in new machines added to your Kubernetes fleet? The trusting-trust problem only works if there is someone to trust.

    Well companies lock "frontier LLMs" behind paywalls, and I don't want to pay for something that still might not be of any use to me

      Gemini 2.5 Pro Experimental (a frontier model) has 5 RPM and 25 RPD.

      Gemini 2.5 Flash Preview 04-17 another powerful model has 10 and 500.

      OpenAI also allows you to use their API for free if you agree to share the tokens.

It sounds like the tool (as it's currently set up) may not actually be that effective at writing tutorial-style content in particular. Tutorials [1] are usually heavily action-oriented and take you from a specific start point to a specific end point to help you get hands-on experience in some skill. Some technical writers argue that there should be no theory whatsoever in tutorials. However, it's probably easy to tweak the prompts to get more action-oriented content with less conceptual explanation (and exclamation marks).

>> This can probably be mitigated by refining the prompt

Sometimes it explains things like I am a child and sometimes it doesn't explain things well enough. I think fixing this just by a simple prompt change won't work - it may fix it in one part and make things worse in the other part. This is a problem which I have with LLM: you can fine-tune the prompt for a specific case but I find it difficult to write a universally-working prompt. The problem seems to be LLM "does not understand my intents", like it can't deduce what I need and "proactively" help. It follows requirements from the prompt but the prompt has to (and can't) handle all situations. I am getting tired of LLM.

exactly it is. I'd rather impressive but at the same time the audience is always going to be engineers, so perhaps it can be curated to still be technical to a degree? I can't imagine a scenario where I have to explain to the VP my ETL pipeline

    From flow.py

    Ensure the tone is welcoming and easy for a newcomer to understand{tone_note}.

    - Output only the Markdown content for this chapter.

    Now, directly provide a super beginner-friendly Markdown output (DON'T need ```markdown``` tags)

    So just a change here might do the trick if you’re interested.

    But I wonder how Gemini would manage different levels. From my take (mostly edtech and not in English) it’s really hard to tone the answer properly and not just have a black and white (5 year old vs expert talk) answer. Anyone has advice on that?

      This has given me decent success:

      "Write simple, rigorous statements, starting from first principles, and making sure to take things to their logical conclusion. Write in straightforward prose, no bullet points and summaries. Avoid truisms and overly high-level statements. (Optionally) Assume that the reader {now put your original prompt whatever you had e.g 5 yo}"

      Sometimes I write a few more lines with the same meaning as above, and sometimes less, they all work more or less OK. Randomly I get better results sometimes with small tweaks but nothing to make a pattern out of -- a useless endeavour anyway since these models change in minute ways every release, and in neural nets the blast radius of a small change is huge.
