As an aside, people say AI will eliminate coding jobs, but then who will configure these hooks? Or think about adding such a feature?

These kinds of tooling and related work will still be there unless AI evolves to the point that it even thinks of this and announces this to all other AI entities and they also implement it properly etc.

To misuse a woodworking metaphor, I think we’re experiencing a shift from hand tools to power tools.

You still need someone who understands the basics to get the good results out of the tools, but they’re not chiseling fine furniture by hand anymore, they’re throwing heaps of wood through the tablesaw instead. More productive, but more likely to lose a finger if you’re not careful.

And we may get an ugly transitory period where a lot of programs go from being clearly hand made with some degree of care and some fine details that show the developer's craftsmanship, to awful prefab and brutalist software that feels inhuman, mass-produced, and nothing is really fit for the job but still shipped because it kind of works well enough.

People go to museums to admire old hand-carved furniture and travel to cities to admire the architecture of centuries past made with hand-chiseled blocks. While power tools do let people make things of equal quality faster, they're instead generally used to make things of worse quality much, much faster and the field has gone from being a craft to simply being an assembly line job. As bad as software is today, we're likely to hit even deeper lows and people will miss the days where Electron apps are good compared to what's yet to come.

There's already been one step in this direction with the Cambrian extinction of 90s/early 2000s software. People still talk about how soulful Winamp/old Windows Media Player/ZSNES/etc were.

I think it's going to go the opposite way: we'll get a lot more custom made software, that fits exactly what a small customer needs. The code might be utter crap, the design might not be award winning, but it will be custom made to a degree that you can't customize your average Savas.

I think the kind of people, who in the past constructed extremely useful (if brittle) solutions with Excel, will be creating all sorts of AI bespoke and very useful tools.

It won't bother them at all what the code looks like under the hood. Not that the code will look worse that what an "average" developer produces. Claude and ChatGPT both write better code than most of the existing code I usually look at.

Better than poorly formatted code, making basic mistakes like SQL query string concatenation, from someone who didn't bother to write any tests. You just have to treat it like code you got from someone else. It would be hard for AI to produce more magical errors that are harder to debug than what humans write. LLMs are one of the best debugging tools out there too.

I kinda feel differently - it's more like how nowadays you have access to high-quality power tools at cheap prices, and tons of tutorials on Youtube that teach you how to do woodworking, and even if you can't afford the masterwork furniture made by craftsmen, you don't have to buy the shitty mass produced stuff - sure yours won't be as good, but it will be made to your spec.

Moving on into a concrete software example, thanks to AI productivity, we replaced a lot of expensive and crappy subscription SaaS software with our homegrown stuff. Our stuff is probably 100x simpler (everyone knows the pain of making box software for a diverse set of customer needs, everything needs to be configurable, which leads to crazy convoluted code, and a lot of it). It's also much better and cheaper to run, to say nothing of the money we save by not paying the exorbitant subscription fee.

I suspect the biggest losers of the AI revolution will be the SaaS companies whose value proposition was: Yes you can use open source for this, but the extra cost of an engineer who maintains this is more than we charge.

As for bespoke software, 'slop' software using Electron, or Unity in video games exists because people believe in the convenience of using these huge lumbering monoliths that come with a ton of baggage, while they were taught the creed that coding to the metal is too hard.

LLMs can help with that, and show people that they can do bespoke from scratch (and more importantly teach people how to do that). Claude/o3/whatever can probably help you build a game in WebGL you thought you needed a game engine for.

Hence the transitory period.

We went through decades of absolutely hideous slop, and now people are yearning for the past and learning how to make things that are aesthetically appealing, like the things that used to be common.

I think we're looking at at least a decade of absolute garbage coming up because it's cheap to make, and people like things that are cheap in the short term. Then people will look back at when software was "good", and use new tools to make things that were as good as they were before.

And not limited to AI and power tools, it happened with art as well. Great art was made with oil paints, watercolors, and brushes. Then digital painting and Photoshop came around and we had a long period of absolute messes on DeviantArt and a lot of knowledge of good color usage and blending was basically lost, but art was produced much faster. Now digital artists are learning traditional methods and combining it with modern technology to make digital art that can be produced faster than traditional art, but with quality that's just as good.

2005 digital paintings have a distinct, and even in the hands of great artists, very sloppy and amateurish feel. Meanwhile 2020s digital artists easily rival the greats of decades and centuries past.

Feels more like photography. Everyone will “soon” have a tool that lets you take pretty great photos - surpassing professional of thirty years ago.

If you want professional work done you’ll still hire someone but that person will also use a lot of professional grade computer tooling with it.

But there definitely won’t be as many jobs as before - especially on the low skill end.

Yea man, people say combine harvesters will eliminate agriculture jobs, but then who will operate these combine harvesters? Obviously every single manual farm laborer will just switch to being an operator of those.

Barring population growth, there is essentially fixed demand for agriculture. For software we don’t know what the market will look like once everything about making it gets automated. Either we will churn out the same amount of software with fewer people, or the same amount of people will churn out larger amounts of software. Or maybe there will be even more people working on creating enormous amounts of software. I’d say the likely answer is somewhere between the first and second option, but time will tell.

If software becomes cheaper to make it’s not like every IT company in the world is running a cartel where they agree to just cut costs and leave the output the same. Someone will come and smash the competition with more or better features and the ones who didn’t invest into development will face pressure to acquire more talent again.

There really isn’t a diminishing return on executing great ideas. Almost all software projects have an essentially endless backlog of items that could be done. So I think it will be between 2. and 3. with people who really understand how software is built being even more in demand than ever since they act as multipliers in making sure the increased output is evolvable and maintainable.

.claude/settings.local.json fragment:

  "hooks": {
    "PostToolUse": [
      {
        "matcher": "Edit|MultiEdit|Write",
        "hooks": [
          {

            "command": "jq -r '.tool_input.file_path' | xargs bin/save-hook.sh"
          }
        ]
      }
    ]
  }
I jumped at this HN post, because Claude Code Opus 4 has this stupid habit of never terminating files with a return.

To test a new hook one needs to restart claude. Better to run the actual processing through a script one can continually edit in one session. This script uses formatters on C files and shell scripts, and just fixes missing returns on other files.

As usual claude and other AI is poor at breaking problems into small steps, and makes up ways to do things. The above hook receives a json file, which I first saved to disk, then extracted the file path and saved that to disk, then instead called save-hook.sh on that path. Now we're home after a couple of edits to save-hook.sh

This was all ten minutes. I wasted far more time letting it flail attempting bigger steps at once.

Find it a bit odd they didn't model this as an MCP server itself, and making hooks just mcp tools with pre-agreed names.

Wouldn't it be nice to have the agent autodiscover the hooks and abstracting their implementation details away under the mcp server, which you could even reuse by other agents?

Yes, I abandoned Cursor recently and went back to Claude Code. Two main reasons: 1. The “plan mode” for Claude makes it execute complex tasks much more reliably. It automatically keeps track of todos and completes them. With Cursor I’m constantly fighting with it. 2. I can now use my IDE of choice (JetBrains) rather than a poor fork of VS Code. 3. Daily usage limits now included in the monthly $20/month Claude Pro plan seems to be enough for my daily needs. No extra costs.

I used GitHub copilot in my vscode setup. Claude Code is its agent mode on steroids: highly configurable, seems to have much larger context window, can write "memories", has hooks now. Highly recommend trying it out.

The time it saved me in first few hours of use easily made the monthly fee worthwhile. I did hit a limit near the four-hour mark (resets every five hours for us Pro subscribers), but just went and reviewed the ~1700 lines it added in that time and cleaned up the config files (updated todos etc)

This closes a big feature gap. One thing that may not be obvious is that because of the way Claude Code generates commits, regular Git hooks won’t work. (At least, in most configurations.)

We’ve been using CLAUDE.md instructions to tell Claude to auto-format code with the Qlty CLI (https://github.com/qltysh/qlty) but Claude a bit hit and miss in following them. The determinism here is a win.

It looks like the events that can be hooked are somewhat limited to start, and I wonder if they will make it easy to hook Git commit and Git push.

This doesn’t come without consideration. You can see I mention this in the original feature request.

Yes - it’s fine to think of it as handholding (or handcoding). These model providers cannot be responsible for ultimate alignment with their users. Today, they can at best enable integration so a user, or business, can express and ensure their own alignment at runtime.

The nature of these systems already requires human symbiosis. This is nothing more than a new integration point. Will empower agents beyond today’s capabilities, increase adoption.

I've been playing with Claude Code the past few days. It is very energetic and maybe will help me get over the hump on some long-standing difficult problems, but it loses focus quickly. Despite explicit directions in CLAUDE.md to build with "make -j8" and run unit tests with "make -j8 check", I see it sometimes running make without -j or calling the test executable directly. I would like to limit it to doing certain essential aspects of workflow with the commands I specify, just as a developer would normally do. Are "Hooks" the right answer?

The AI definitely gets confused when there is a lot of stuff happening. It helps if you try to make the commands as easy as possible. Like, change 'make' so that '-j8' is default, or add scripts like make-check.sh that does 'make -j check', or add an MCP server that has commands for the most common actions (tell the AI to write an MCP server for you).

Hooks would probably help, I think you could add a hook to auto-reject the bot when it calls the wrong thing.

Claude Code has basically grown to dominate my initial coding workflow.

I was using the API and passed $50 easily, so I upgraded to the $100 a month plan and have already reached $100 in usage.

I've been working on a large project, with 3 different repos (frontend, backend, legacy backend) and I just have all 3 of them in one directory now with claude code.

Wrote some quick instructions about how it was setup, its worked very well. If I am feeling brave I can have multiple claude codes running in different terminals, each working on one piece, but Opus tends to do better working across all 3 repos with all of the required context.

Still have to audit every change, commit often, but it works great 90% of the time.

It is all file based, so yes you can if you do what OP said: `git clone repo-one && git clone repo-two` and tell claude that repo-one directory is for example frontend, repo-two is backend (or better name the directories after what they are)

Just started using Claude (very late to the game), and I am truly blown away. Instead of struggling for hours trying to get the right syntax for a Powershell script or to convert Python to Go, I simply ask Claude to make it happen. This helps me focus on content creation instead of the mind-bending experience of syntax across various languages. While some might call it laziness, I call it freedom as it helps me get my stuff done quicker.

I have been using it for other stuff (real estate, grilling recipes, troubleshooting electrical issues with my truck), and it seems to have a very large knowledge base. At this point, my goal is to get good at asking the right kinds of questions to get the best/most accurate answers.

I'm pretty sure that the $100 / $200 plans are a net profit for Anthropic. Most users (including myself) don't come close to the usage limit.

I've been trying to max out the $100 plan and I have a problem where I run out of stuff to ask it to do. Even when I try to have multiple side projects at once, Claude just gets stuff done, and then sits idle.

It can still be a lot more expensive and be cheaper than a human, it might mean less chance taking and spending the money to try set it up and see if it works though. More existing setups, less new setups.

I have been using Claude to iterate through some complex Powershell code to convert Azure VMs from Intel to AMD SKUs, and I simply can't believe how good it is. I am definitely NOT an Azure or Powershell expert by any means, but the power and ease of idea iteration is truly a game changer (I have been in IT since about '91). Yes, Claude makes some mistakes - typically with certain command arguments, but I am able to lean on my experience to work through those issues.

What would have taken me a week to get up-to-speed with Powershell and all the Azure powershell commands/syntax has now taken me about 4hrs.

This nicely describes where we're at with LLM's as I see it: they are 'fancy' enough to be able to write code yet at the same time they can't be trusted to do stuff which can be solved with a simple hook.

I feel that currently improvement mostly comes from slapping what to me feels like workarounds on top of something that very well may be a local maximum.

Humans are fancy enough to be able to write code yet at the same time they can’t be trusted to do stuff which can be solved with a simple hook, like a simple formatter or linter. That’s why we still run those on CI. This is a meaningless statement.

We cant deny the LLM has utility. You cant eat the stone but the LLM can implement design patterns for example.

I think this insistance on near autonomous agents is setting the bar too high, which wouldnt be an issue if these companies werent then insisting that the bar is set just right.

These things understand language perfectly, theyve solved NLP because thats what they model extremely well. But agentic stuff is modelled by reinforcement learning and until thats in the foundation model itself (at the token prediction level) these things have no real understanding of state spaces being a recursive function of action spaces and such stuff. And they cant autonomously code or drive or manage a fund until they do

Given the Anthropic legal terms forbid competing with them, what are we actually allowed to do with this? Seems confusing what is allowed.

No machine learning work? That would compete.

No writing stuff I would train AI on. Except I own the stuff it writes, but I can’t use it.

Can we build websites with it? What websites don’t compete with Anthropic?

Terminal games? No, Claude code is a terminal game, if you make a terminal game it competes with Claude?

Can their “trust and safety team” humans read everyone’s stuff just to check if we’re competing with LLMs (funny joke) and steal business ideas and use them at Anthropic?

Feels like the dirty secret of AI services is, every possible use case violates the terms, and we just have to accept we’re using something their legal team told us not to use? How is that logically consistent? Any safety concerns? This doesn’t seem like a law Asimov would appreciate.

It would be cool if the set of allowed use cases wasn’t empty. That might make Anthropic seem more intelligent

The TOS says (https://www.anthropic.com/legal/consumer-terms):

You may not access or use, or help another person to access or use, our Services in the following ways:

2. To develop any products or services that compete with our Services, including to develop or train any artificial intelligence or machine learning algorithms or models or resell the Services.

Let's say you've used Anthropic's model to generate open source software and then some 3rd party trains their model on that. Have you now helped another person to use their service in a way that violates the terms?

I suppose that's pretty far-fetched, though, unless you have some interaction with the party doing the training. Sometimes you might, though: perhaps some company provides services to train a model on exactly your code base, and then provide similar service as Anthropic does for your code base, thus being in direct competition of Antropic as well.

I have a side project Android app. To test Claude Code, I loaded it up in the repo and asked it to add a subscription billing capability to the app. Not rocket science, but it probably would have taken me a day or two to figure out the mechanics of Google Play subscription billing and implement it in code.

Claude Code did it in 30 seconds and it works flawlessly.

I am so confused how people are not seeing this as a valuable tool. Like, are you asking it to solve P versus NP or something?

If you need to do something that's been done a million times, but you don't have experience with it, LLMs are an excellent way to get running quickly.

Its definitely not there yet. You have to babysit it alot. Its not autonomous.

The utility i find is that it helps _me_ do the real engineering work, the planning and solution architechting, and then can bang out code once it has rock solid instructions (in natural language but honestly one level above psuedocode) and then i have to review it with absolutely zero faith in its ability to do things. Then it can work well.

But its not where these guys are claiming it is

Interesting how long ago did you do this? How long did you spend on it?

I was skeptical about Claude code and then I spent a week really learning how to use it. Within the week I had built a backend with FastAPI that supported user creation, password reset, email confirmation, a front end, and support for ouath into a few systems.

It definitely took me some time to learn how to make it work, but I’m astounded at how much work I got done and for so little typing.

How do you know the code is solid? If your bar is “if it runs, then it is good”, then alright, otherwise you (or someone else) need to review that code. So, Yeah llms are nice but i don’t think we can just go and deploy whatever they throw at us.

Do you allow interns to push to prod? Because I don't. The LLM is treated no differently. It's an extraordinarily fast, extraordinarily well read intern. You can ask it to do anything, it might succeed, anything it produces should be reviewed fully. I already interact with interns and open source project contributors in a similar fashion, so the LLM plugs right in.

"I wanted something that I think it was not done before"

But you do know, that this is what LLMs ain't good at.

So your conclusion is somewhat off, because there are plenty of programming work of things that were done before and require just tweaking.

I mean, I am also not hooked yet and just occasionally use chatGPT/claude for concrete stuff, but I do find it useful and I do see, where it can get really useful for me (once it really knows my codebase and the libaries used and does not jump between incompatible API versions)

Yes that is a very accurate assessment, I use Claude almost all the time for other tasks, but when it was a moment to really put it to the test I was not able to produce anything at least usable.

My request involved a local web application that acted as a server for other clients in the same network using Rust.

I wanted to use websockets, it never worked and I was never able to nudge it in any meaningful direction, it started to make circular edits on the codebase and it just never worked.

So many people yearn for LLM's to be like the Star Trek ship computer, which when asked a question unconditionally provides a response relevant and correct, needing no verification.

A better analogy is LLM's are closer to the "universal translator" with an occasional interaction similar to[0]:

  Black Knight: None shall pass.
  King Arthur: What?
  Black Knight: None shall pass!
  King Arthur: I have no quarrel with you good Sir Knight, But I must cross this bridge.
  Black Knight: Then you shall die.
  King Arthur: I command you, as King of the Britons, to stand aside!
  Black Knight: I move for no man.
  King Arthur: So be it!
  [they fight until Arthur cuts off the Black Knight's left arm]
  King Arthur: Now, stand aside, worthy adversary.
  Black Knight: 'Tis but a scratch.
  King Arthur: A scratch? Your arm's off!
  Black Knight: No, it isn't.
  King Arthur: Well, what's that then?
  Black Knight: I've had worse.
