I am not sure whether I love the plan + code workflow, but when I do it, I do /clear and instruct "implement PLAN.md" or whatever. (Probably better to do /goal implement PLAN.md; I haven't tried it though.)

I put context size in my Claude Code status bar and ... it does get "tired" when it's at 50%-60% context. I figured this out when I'm like "now modify the testbed to run this and add a test to exercise blah blah blah" and it was just like "That would be a substantial infra lift." In my head I say "I am paying a substantial amount for you to do this!" but just type /compact and re-prompt and my "substantial infra lift" is done without complaint.

I guess everyone needs a nap after a long day of conversing and writing code. So like us!

/compact is prone to error and I wouldn't recommend it in the middle of work. But when you are switching to a related but not completely new task, it helps. ("Now write the integration tests." vs. "on foo.go line 476 that you just wrote, I think there is a deadlock with bar.go line 123 that you just added". It doesn't really need the context to write the tests, it can get that by reading the code. But for iterating on lines of code it just produced, /compact is going to throw away whatever "thought process" led to that code and it's usually not a great thing to do.)

I think the comment you're replying to is talking about cost and speed, and Opus 4.8 xhigh is pretty expensive and pretty slow. I work around the slowness by having multiple auto mode sessions going in parallel (review this, investigate that, plan this, etc.; and yes, I use a VM that can't touch prod for auto-mode work), and work around the cost by my employer pays for it and everyone else I work with uses more AI than I do :)

I really really like Fable for software engineering cases; add an alert and write a runbook, go pull metrics for this incident, write me a TUI that does blank, etc. It is astoundingly good and I am very picky. It costs A LOT of money though. I am not sure how I get away with my Fable usage.

Sort by price ascending and pick the first result.

I think 100% of the books I've read in the last year have been recommendations from friends. This is kind of annoying as I'd like to be able to give them recommendations in return, but ... limited time.

I wish that I could doomscroll literature instead of short videos, but the economics apparently don't work out.

You're right. Fable 5 did not enjoy this question, but no doubt future models will.

Yeah. I would personally refuse to add Helm to a system but the complicating factors are 1) customers ask for it by name (why I relented at my last job where we made self-hosted k8s software) 2) people we hire know how to use it. So while I find it unpleasant from a computer science purity standpoint, it is pretty popular and gets the job done. I have to save my energy for things that matter and improve the experiences of the customers, not design the 900th way to deploy stuff to Kubernetes. So ... I am happy to let Claude double-check my {{ brace }} nesting or whatever. If something is Objectively Terrible but tooling smooths over it, I can let it live without a fight.

I like the prompt injection attempt on the footer:

This reminds me of Slashdot commenters back in the day that tried to include words like "bomb" in their signatures in the hopes of flagging some government system. I am glad that people haven't gotten tired of this sort of tomfoolery and have adapted it for a modern world :)

I don't really agree with this. I was VERY skeptical about AI, but then I started using frontier models everyday, and my feelings have changed dramatically. I use AI to refine designs. I use AI for "where are all the codepaths where we return an HTTP 499 error". I use AI to write code (in "manually accept edits" mode, and I am picky about every single diff) and the results are really good. Most of the time, exactly what I typed in. Doing stuff like "add this config and plumb it through the helm chart" is amazing. Editing Go templates that generate YAML is absolutely miserable, it is my least favorite task. Claude gets it right without fuss every time.

I have not stopped engineering software, but I type in less code. I still understand every line in our codebase and why it's there, but I spend a lot less time dealing with the mechanics. LLMs are super impressive for the software engineering work I do. I don't have a fleet of agents making 20 major changes to the codebase every day. I do about as much work with AI as I did before I used AI. But I think the quality has gone way up, and I am a stickler for pretty perfect code. Claude keeps me honest and reduces the cost of exploring alternate approaches, writing hairy tests, doing refactors, keeping docs up to date, keeping production stable and understandable, etc.

I basically do not agree with this article at all. Frontier models are like switching from dabbrev-mode to IntelliSense, something I was very resistant to at the time. "It's important that I know the APIs that I use everyday." Not really. Having your IDE remember whether it's HasPrefix(string, substring) or HasPrefix(substring, string) frees up my brain for something more important and I couldn't live without it. AI is the same way. It's a tool that makes me better at my work. Yes, it's expensive. That's the only downside I see. I am lucky that I can use as much Fable 5 as I want at work... I always feel bad when I share something that it did that was cool with someone who can't afford it. But costs will come down. I think this AI think is here to stay in the software engineering space. I don't think it removes the need for qualified software engineers at the controls. At least today.

I worked on GFiber in the mid 2010s. We were having a debate about IPv6 support, which many people wanted to not do. I wrote a far-too-long essay on why it was important (at the time) and Vint picked it up to yell at the leadership team to get it prioritized. It was truly an "only at Google" experience to have someone who essentially invented the Internet reading your posts and acting on them.

(I guess a decade later, was IPv6 important? Still not sure about that one. But it seemed important at the time.)

Yup, a nice tool.

I think we can learn from history about where this is headed. I remember when each developer needed a $600 compiler to write C++. Eventually that industry was replaced by free compilers. Kind of a similar thing going on with frontier models; I really like Fable 5, but if I didn't have any money I'd use GLM 5.2 or something. Since my employer does have money to spend on it, I enjoy the productivity boost (just like Intel's C++ compiler produced faster code than gcc for a while), but you can see the direction things are going. Eventually the moat around Anthropic and OpenAI collapses, and AI coding assistance is something built into every text editor.

There is still probably a lot of upside on betting that some lab produces a model that is light years ahead of what we have today. But I feel less "I'd better start planning for a new career" than I did a year ago.

I am not sure that it has to be so zero sum. The AI truth is probably somewhere in the middle; it probably doesn't replace software engineers and it probably won't be deleted as completely useless. My current feeling is that it's a powerful tool I'm happy to pay to use; it doesn't replace me, but it makes it easier to do higher quality work. It feels a lot like IntelliSense, or faster compilers, or getting a 32" monitor. That probably doesn't sustain the bubble, but it's something that people are going to be poking at and making money off of for a long time.

I agree that people are investing as though the world is going to run itself while the ultra-wealthy run off in yachts to compare sizes. If it wasn't AI, it would just be tulips or something. That's just how people are. But maybe they'll be right, who knows.

I came here to post this as my experience. AI is magical when I apply it to something I know nothing about. It far exceeds my expectations every single time. I know nothing, but here is a report with animated graphics explaining exactly what I asked it to explain!

In fields where I'm an expert... it makes a lot of silly mistakes that are annoying and I feel like they would just cascade if I didn't correct them early. (I still think it's a net win, but... I watch it and it watches me, and we both do better work. I'd even apply the "magical" adjective when it does stuff I hate but know how to do, like edit Helm charts. What would normally be 20 minutes of me griping about YAML indentation is just a correct diff in seconds. I'll take it!)

So with that in mind, I tend to distrust output that I can't verify. If a doctor was recommending surgery and I thought the plan was too aggressive, I'd get a second opinion. I don't expect Claude Code to have much medical diagnostic ability, as that is really not what the model is trained for, and I know how it performs on work that it's trained and fine-tuned for. That is not to say the output is wrong and that it can't have diagnostic value, just that I personally wouldn't feel safe trusting it. Wrap up the same model with fine-tuning in the domain and a harness that reminds Claude to do a lot of sanity checks, perhaps with a human in the loop to guide it back onto the rails when it gets hyperfixated on something that doesn't matter? That could very much be a useful AI product.

That's true, local models are good. The Tandy 1000 was really only good for a little bit QBASIC. Still fun!

The other is that computing in general feels more accessible? While some models are free, you still can't easily make your own model. But I see the argument where you can't really just build your own computer anymore (no one person knows how to make a modern CPU, and you can't do it at home). You are always beholden to society, nothing truly starts in your basement at home. And it didn't in the nostalgia era that I remember either.

The 10th amendment to the Constitution reads "The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people."

I agree with this. Computing as a field is the way it is because there is a low barrier to entry. My dad gave me a Tandy 1000 and some programming books, and now I have a very lucrative career. I never took any classes. I never had to beg anyone for permission. I could just get started making things with the minimal investment of a cheap personal computer. (And eventually, an Internet connection. Working with other people is fun!)

In a world where everyone is a Claude controller (something I honestly enjoy!), that goes away. I use hundreds of dollars of tokens a month. Suddenly, the kid in her basement with an unloved computer can't get in on the ground floor. You have to be rich to even get started. That worries me deeply. It's a big change for our field, and I don't think it's a good one.

How does Red Hat prevent Chinese companies from producing a Linux distribution for free? They don't. And yet they still exist.

I agree with you. I used to work for an ISP that sold kind-of overpriced 1Gbps connections and always wondered why customers bought it. Probably helping things was that we took them out to "events", floor seats at basketball, etc. The company just has a fixed expense, but the people making the decision get free stuff that makes them feel important, and it was kind of a way of transferring the company's money (by not buying the $29/month Internet connection) to themselves. I never felt good about it, but if you say that out loud, everyone will look at you like you're crazy.

AWS did this for us at the time but the 3 people in the company that used AWS services never got to go to these things. So I doubly don't get it.

Sure, but why do I care? Let them run the legacy links. Just don't make my phone ring.

I agree with this experience. LLMs are great and save me a lot of time, but they need frequent nudges to avoid going down a completely wrong path. I just don't feel like the management dream of "every engineer has 3 agents working for them full time" is quite a reality yet. I'm not saying it won't get there, or that I feel secure being a software engineer until I'm of retirement age, but I also think it's important to understand the limitation of the tools. You do need to know your codebase. You do need to iterate on small chunks of it at a time. You do need to carefully understand every line of code you're putting into production. LLMs are amazing at generating a lot of proposals, but you need to carefully consider each one.

Most surprising to me about the article was the desire for OP's company to use AI for design docs. I feel like AI-generated design docs are some of the worst -- basically treating English as a programming language. They aren't enjoyable to read, and they often miss the forest for the trees. A human written sketch explaining why we're here and what we're working towards is still meaningful and important. If you want code-level details of every decision and algorithm, we have code for that.

I have mixed feelings on whether these documents are useful LLM inputs. I did a project where I carefully paired with Claude Code on producing a specification that another model would actually implement. I'm not sure it saved me any time, and it was very un-fun. (I kind of blame Opus 4.7 xhigh for this. It ain't speedy.) I feel like I can nitpick code to get exactly what I want, but defining exactly what I want an auto-mode LLM to go and do, in English, is much more difficult. I don't think the PLAN.md I generated would have been useful for a human trying to understand the system (too verbose), and Claude Code still made its usual mistakes that I have reminded it a billion times not to make (t.Context() in tests, not context.Background()!), so I'm just not sure it was worth it. I would say I probably wouldn't do it again in the near future. A rough sketch to get humans on board and to get the high level details worked out, written by hand, and then pairing with the LLM on actually typing in the code seems the most productive to me. But I do try to go outside my comfort zone once in a while to test the edges of these tools. They are very impressive and are worth a lot of the hype. (I know I will never write a YAML file again. I hate it more than anything, and Claude is amazing at it. But I worry I wouldn't feel the same way if I hadn't already had 8 years of k8s experience.)

There is something appealing about "it's just a file" (it really isn't; it has locks and a WAL), but I agree with you.

I think people are afraid to read the documentation for postgres. You can start it up in milliseconds. Fast enough and light enough to run one copy for every test case in your test suite, or whatever you're using it for. (mkdir /tmp/whatever; initdb -D /tmp/whatever --no-instructions -A reject -c listen_addresses= --auth-local=trust --no-sync -c fsync=off -c unix_socket_directories=/tmp/whatever -U postgres --no-locale; postgres -D /tmp/whatever) Now you have a test database that behaves exactly like production because it's exactly like production. (OK, turning fsync off makes it a lot faster than production, so be careful.)

I think they were intending to evoke the image of RAID rather than literally referring to a redundant array of inexpensive disks. You host your code on Github, Gitlab, and at home, then you survive a Github outage. It's a redundant array. Not sure it's inexpensive, though.

I don't think you can ever trust one service with critical data. Some Claude instance deletes your prod database, you have to restore from an offsite backup because it also deleted your local backups. Even at small startups we did pg_dump to AWS from GCP because ... who knows what is going to happen to GCP, and we want to continue to be in business if that happens.

I don't feel safe with any one single point of failure. "Your credit card bounced", "you thought it was dev", "you got hacked", etc. are all the same problem to me and no cloud provider solves those merely by setting up an account.

Kind of a random aside, but I never realized how obnoxious LEDs were until I got a studio apartment and started sleeping in the same room as my homelab / workstation / networking hardware. Electrical tape saved me, but wow. You sure can produce a lot of light with a milliwatt of electricity :)

(And yes, my workstation has a clear case and LED RAM. Yes, I'm an idiot. Whenever Windows applies an update late at night, I wake up if it turns back on. I don't know what I was thinking when I built that thing, but never again.)

Unfortunately, there is pressure to treat this stuff in good faith. Maybe the PR author really did write all this. Maybe they really did spend 6 hours writing this document.

So, I approach it in good faith, but I do get upset when people say "I'll ask claude". You need to be the intermediary, I can also prompt claude and read back the result. If you are going to hire an employee to do work on your behalf, you are responsible for their performance at the end of the day. And that's what an AI assistant is. The buck stops with you. But I don't think people understand that and that they don't understand they aren't adding value. At some point, you have to use your brain to decide if the AI is making sense, that's not really my job as the code/doc reviewer. I want to have a conversation with you, not your tooling, basically.

I am not sure who would find your comment funny. It's just misogyny, bro.

Doctors have always been into "more patients", though. To some extent, if you're a doctor, the upper bound on your pay is how much you charge * how many patients you see. This is why you occasionally get seen well after your appointment time; people are double booked because some % reliability doesn't show up, but sometimes everyone DOES show up to their appointment and now it's your problem.

So if AI scribes mean "less double booking" then that's kind of a win/win. Less patient time is wasted. Doctors can make more money by seeing more people on a given day. Seems fair.

jj is great and while it was an adjustment at first, I've never looked back. I feel like when you're working with other people, things never get reviewed and merged as quickly as you'd like. With jj, it's pretty low-cost to have a bunch of PRs open at once, and you can do something like `jj new <pr1> <pr2> <pr3>` to build stuff that requires all 3. This lets me do things like... not do a big refactoring in the same PR as adding a feature. I can have them both self-contained, but still start on the next step before they're all merged. It's easy to add changes on top, switching between the individual PRs as comments come up, etc.

I always liked doing things like this. At Google where we used a custom fork of Perforce, I told myself "NEVER DO STACKED CLs HAVE YOU NOT LEARNED YOUR LESSON YET?" If one CL depended on another... don't do it. With git... I told myself the same thing, as I sat in endless interactive rebases and merge conflict commits ("git rebase abort" might have been my most-used command). With jj, it's not a problem. There are merge conflicts. You can resolve them with the peace of mind as a separate commit to track your resolution. `jj new -d 'resolve merge conflict` -A @` to add a new commit after the conflicted one. Hack on your resolution until you're happy. jj squash --into @-. Merge conflict resolved.

It is truly a beautiful model. Really a big mental health saver. It just makes it so easy to work with other people.

Yeah, sorry. Claude Code in my case.

I do use the browser version on occasion. I have no strong feelings one way or the other there. I like it better than Google search in many cases, but probably just search more often.

I have read the HN articles and seen the grumbling from coworkers, but I haven't felt it myself. I am not really a one-shotter, though. I kind of think about how I would refactor / write something myself and walk Claude through that, and nitpick it at each step... and the recent changes haven't really bothered me there. Likely due to being new at it.

Sometimes Claude can be a little weird. I was asking it about some settings in Grafana. It gave me an answer that didn't work. I told it that. "Yeah, I didn't really check, I just guessed." Then I said, "please check" and it said "you should read the discussion forums and issue tracker". I said "YOU should read the discussion forms and issue tracker". It consumed 35k tokens and then told me the thing I wanted was a checkbox. It was! I am not sure this saved me time, Claude. I am not experienced enough to say that this is a deal breaker. While this is burned into my mind as an amusing anecdote, it doesn't ruin the service for me.

My coworkers have noticed a degradation and feel vindicated by some of the posts here that I link. A lot of them are using Cursor more now. I have not tried it yet because I kind of like the Claude flow and /effort max + "are you sure?" yield good results. For now. I'm always happy to switch if something is clearly better.
