    > Throw nine autonomous agents at a single codebase without crystal-clear orchestration, and they will happily rewrite each other's work in a high-speed loop.

    This is an easily solvable "problem". Pretty much all harness/agent orchestrators support spawning subagents/threads with different models and get them to work together cleanly. I don't even need any kind of special skills. Inside a vanilla claude session, I sometimes ask it to use `codex` and review the kind and work on the findings it generates.

    > "Adding agents to a project with unclear requirements gets you the wrong answer faster."

    The thing is it gets you the wrong answer so fast it’s now the best way to figure out the right requirements.

    • matsemann 55 minutes ago
      Not if you turn off your brain. Never actually stop to question the path you're going down, because the speed is making you blind. Which is what I feel I see more and more. Or how do you even know it's the wrong answer if you didn't think it through before starting?

      One example: setting the agent ablaze on some task, keeping it going, and after a few days of working with the agent you have a feature. But it's not what you were supposed to make. The agent didn't have all the context and made something slightly off, and you never internalized the problem enough to even spot it. If you actually stopped to think a bit on how the feature would have to work to tie it in with everything else, like you would have done before, you would've spotted it.

      Second example: something wasn't feasible to do before, due to not being worth the time investment. Like a feature that would need a bigger architectural change to implement. You and the agent take a crack at it, and rewrite huge parts of the code, and it seems to work. But now no one understands how, and it might have been the wrong way to solve it, you just went with it. Before, you would've sat down and discussed and thought about the architectural tradeoffs. Now one decision was just made with little thought.

        Real life is full of unknown unknowns, AI risks putting you on the wrong path without you even realizing it.

        It doesn't help a bit that (almost? I'd say all) AI products are very confident while they're guiding you on that unknown unknown path, so of course that you don't realize soon enough the epistemological situation said AI product has driven you into.

      What's easier to use as inspiration for coming up with a list of requirements?:

      1. A blank sheet of paper

      2. A one-shotted POC in the span of an hour with $4 of tokens that is clearly wrong in 20 different ways?

      • uludag 3 minutes ago
        Obviously "a blank sheet of paper" here is meaning thinking about the problem deeply. I'm surprised how dismissive people are to using brainpower whatsoever. I get that juxtaposing paper to LLMs might have triggered some people though.

        As a counterpoint, bringing a one-shotted POC without thought may actually do have a shock and awe sort of effect, dazzling the stakeholders to go down the wrong path since the AI prototype was so easy.

        > 2. A one-shotted POC in the span of an hour with $4 of tokens that is clearly wrong in 20 different ways?

        A meeting between all the stakeholders to agree on requirements easily runs $1,000/hour. Taking your $4 functional PoC into that meeting is going to save so much time...

        > 2. A one-shotted POC in the span of an hour with $4 of tokens that is clearly wrong in 20 different ways?

        Definitely this. I've had plenty of useless meetings with no helpful outcomes that lasted an hour with 6 or more people in them, and a few of them will have had more than $4 spent on snacks, let alone everyone's wages.

        That said, poor communication will always get you no matter what: had one day spent going back and forth with a client, they kept saying they wanted a button "wider" each time around, I ended up making it full screen width and they still said "wider", asked them to draw a picture and they finally said "wider vertically". That may or may not have been faster with an LLM, depending on if the LLM ever thought to ask the client to draw what they meant, but fundamentally would have been exactly the same problem.

        • tarsinge 30 minutes ago
          It goes beyond this, the job is to understand the underlying need. When a clients asks for a button to be bigger, what's in their head is they fear it's not visible enough. Many times the client was happy when I implemented something unrelated but that solved the issue, like changing the colours to increase the contrast between the background and the button, adding space around, etc. so that it pops out more.

          Using the "let run multiple agents run amok" approach you surely get a lot of "i don't like that part"-feature requests, yes.

          In my opinion, a good engineer is not good because he understands every single obscure technical detail, but because he can build solutions that the people using his technology actually want. The list of things they don't want on the other hand is endless.

        • pydry 32 minutes ago
          Theyre also inclined to jump into talking about solutions rather than their actual problem which inhibits analysis of the problem.

          It was pretty surprising to me when I realised I could put 5 different bug reports into the same message and it would fix all of them.

          Not quite as shocking as the original InstructGPT video, but surprising.

          • eterm 27 minutes ago
            What's even more surprising is that it can be given a grafana API key and reason about bugs from the hints of patterns in the logs even with pretty sketchy and inconsistent logging in places.

            It can then raise, investigate and resolve those problems while also patching up and rationalising logging to improve future work.

            The AI deniers have their heads in the sands at this point and are demonstrating they simply haven't tried a modern agent. ( Or perhaps are forced onto copilot? )

              Could be either, but also the free version of ChatGPT seems rather braindead compared to the paid version, or to the free version of Claude.

    • Terr_ 1 hour ago
      That depends on (A) verification being very low cost and (B) being able to infer the right answer based on wrong ones.

      Those aren't always true. Sometimes it takes a while to see the fatal flaw in an approach, and sometimes having a bunch of failed attempts isn't enough to make the right way obvious, and thinking is still required.

      • ben_w 41 minutes ago
        Good points. This is after all why LLMs are so much better at maths and software than the economy in general.

      I guess that’s just the old “Build One To Throw Away” in a modern light, where prototyping more freely is now actually feasible. I think if you apply the good engineering ideas of the past decades to AI, the results can be really good!

      Except I’d also add a lot of testing to the prototype, to bring up as many edge cases as possible.

    • rpunkfu 1 hour ago
      I was talking about it for a while with colleagues. AI besides other benefits, needs to be treated as great interface for discovery, you have your features baked in, AI uses it via your users and MCP, then you figure out what are actual flows of my users and then you build it
    • paganel 19 minutes ago
      > The thing is it gets you the wrong answer so fast

      If oftentimes happens that you don't know that that's the wrong answer, or you don't realize it right away, for that matter, and hence that's I think that AI is a new (and very big and important) source of information entropy.

      Just a recent personal example, yesterday I was curious about the historical figure that was present in an online photo taken in 1930s Romania. Google's Gemini was very quick to point out that that was (military dictator) Ion Antonescu [1], which it was obvious that he wasn't. I wrote down that that wasn't in fact Ion Antonescu, at which point Gemini was very quickly and very surely providing me the info that that guy indeed wasn't Ion Antonescu, but (former Foreign Affairs) minister Manoilescu. At this point I wasn't so sure myself, I don't have a visual image of Manoilescu in my head, so (ironically) I had to AI-dumb google for Manoilescu's available online images and it seemed like Gemini had been wrong a second time. I didn't bother asking it for a third time.

      Just to put things into perspective, here in Romania it is illegal to mention Ion Antonescu's name (and propaganda image) in a positive matter, as in one risks prison for doing that, now, just imagine that the political powers that be here decide to use an AI-tool like Gemini in order to identify potential law-breakers in that respect. People would risk going to jail just because Google's Gemini was completely wrong in identifying a WW2 military dictator. Absolutely atrocious product(s).

    The author misapplies/misunderstands the mythical man month even in the first example. It does not apply for idea generation and also not to problem solving/ fixing things, only to software creation. Even then, it also does not apply when creation is cheap, if you can generate 100 solutions cheaply without coordination between them and pick the winner with a relatively fast eval, creation behaves way more like fixing / problem solving.
  • comboy 1 hour ago
    Related thing is that LLMs are still notoriously bad at writing instructions for themselves (so managing themselves also). They tend to overspecify. If I had a copy of myself I would tell him "do the thing", but agents say "do the thing like this and this, it must be such and such, use X and put it together that way". The subagent is just as intelligent but now it's constrained, sometimes as you start developing something you discover some things are better organized in a different way etc. So it spends much time figuring out how to deliver exactly what was asked even if it's not optimal because that's the task.

    Basically a company where you can't ever question decisions of the higher ups, not even ask for clarification, but they force implementation choices on you. I mean, it definitely does happen, but the results are usually not great. Not alawys. For some tasks it works.

    • nextaccountic 26 minutes ago
      > Related thing is that LLMs are still notoriously bad at writing instructions for themselves (so managing themselves also).

      Isn't this odd? This seems to be the #1 task that the major labs should be optimizing, since it makes agent so much more effective.

      Isn't this just the planning pattern, common for agentic work? (first plan then implement.. with things like /plan, or a planning skill, with or without creating a PLAN.md). If this methodology is wrong when an agent prompt another agent, it's also wrong when the human runs /plan manually..

      And Indeed, I always thought it was odd to constrain the implementing agent like that, because common sense is that we discover things as we implement. Perhaps we should prompt the agent to communicate back, as they implement, any shortcomings in the plan itself - such as things they learned while implementing that contradicts the plan.

      > The subagent is just as intelligent

      Isn't it a common practice to use cheaper models to do the grunt work?

      • sunaurus 49 minutes ago
        Does this actually work for anybody? In my experience, when you use cheaper models as subagents, the more expensive parent agent ends up reading all of the subagent's work and surrounding code into context anyway to review it. So you end up paying more, not less.
        • murkt 43 minutes ago
          When I am making agents do a hard thing, I use Opus as both parent and child. I make the child review its code extensively, and then still make the parent read the work and review once again. It is much faster and cheaper than just rolling with no extra reviews, and then in a day I have fifty subtle bugs.
        • antihipocrat 46 minutes ago
          Plus the subagent's work is often subpar and the parent ends up requesting multiple revisions. Each back and forth burn unnecessary tokens as well as my time.

          Where it might work well is for separate task categories like image generation - get the parent to ask for an image from another model that is better at this aspect

    But it’s not a man-month anymore. It’s like half a day.

    And if I break up an application then 9 coders with Claude Code can build that application in an unprecedentedly short period.

    • yread 14 minutes ago
      > 9 coders

      How do you do that? If I let just 2 agents work in parallel they keep stepping on each other, waiting for each other and the perf tests become super noisy (because they run them in parallel)

    • otabdeveloper4 56 minutes ago
      > Claude Code can build that application in an unprecedentedly short period

      Yes, with the caveat that the application doesn't actually work.

      P.S. If you wrote non-working applications even before the age of AI, then this is an upgrade, I guess.

    • bingemaker 1 hour ago
      There is a difference between building a product and building a product that sells. So, which one are we talking about here? In my opinion MMM talks about the latter
      • _puk 31 minutes ago
        If you've got 9 coders, you've at least got a business idea and some financial backing.

        Get it out quickly, market it, iterate it. That hasn't changed. Just the speed of iteration before you go from product to product that sells.

        Once you know what sells, then again, it takes far less time to rebuild it well if you need to.

      • Gigachad 1 hour ago
        If you can vibecode a product that sells, I can vibecode a free open source one just as easily, probably even easier since I can just ask the AI to copy the existing one. Software is trending towards being free and open source.
        • _puk 28 minutes ago
          Yeah, and then who maintains it?

          Maintaining vibe coded software is going to become hours spent with Claude not your users.

          That's going to be the difference. It takes nothing to rebuild the software, but listening to users, iterating, handling issues. That's boring.

          The ones that win will be the ones that stay the course, not the ones that were built the quickest.

        • pydry 29 minutes ago
          Half of the value in open source was that it was used by lots of people and all of the nasty edge cases and bugs have been ironed out.

          If LLMs were performing according to hype then yes, virtually all paid software would be gone by now and there would be a high quality FOSS equivalent of all of it.

        • sedan_baklazhan 58 minutes ago
          In the good old days that was called 'piracy'.
          • ben_w 34 minutes ago
            Unclear if this is that. If someone makes their own FOSS Photoshop, that's not piracy, it's GIMP. Training a AI on things that one otherwise has lawful access to (and not, e.g., pirating the material which Meta is being sued over and Anthropic settled over) has been ruled lawful.

            Is asking an LLM to "make an open-source Photoshop clone" more like GIMP, or more like opening someone else's photo in Photoshop and clicking the menu option for the filter to make it look like a stained glass window and claiming the stained glass window version is your own IP that doesn't need permission from the original creator?

            We may need new IP laws. Or, to the horror of many software developers 20 years ago, software patents.

            And "new IP laws" doesn't mean "stronger": the justification for giving creators a monopoly on their works (the right to copy, or copyright) is to encourage more. If we've got a machine to automate this, there's suddenly no reason to encourage more.

  • hypfer 1 hour ago
    Agents seem to be useful for quickly mapping a problem space through trial&error + throwing stuff at the wall and seeing what sticks.

    Anything grindy. Reverse engineering. Performance optimizations.

    That's where swarms shine I think. But that's a much much much smaller problem space than what these agents are being sold for.

    • edot 1 hour ago
      Right, the key being a fast feedback loop. I have full confidence that the same LLMs that can do these crazy math proofs could also do crazy biology, even cancer research, but they simply don’t have the cycle time low enough because they require actual physical experiments, often on living things, often over long time horizons. Even if you perfectly automated a lab, made thousands of them, you’d still be unable to match the speed of iteration that one gets with pure math and computing problems.

    i think of the mythical man-month at least once a day.

    if i would know EXACTLY what and how I had to build stuff, it would probably not apply. But at least for me and my projects, that is not the case. Planning and building in parallel has given me too many headaches.

    If you are building something stable, secure - well thought through and executed, you hardly get around sequential building.

    • Joel_Mckay 1 hour ago
      In my experience, you choose the key difficult parts first, and build a small toy version. From that action, you learn which parts of the interfaces are common, and may undergo modularization with a clean design pattern.

      Ultimately with sanity checking, sanitized marshaling, and constraint programming... the underlying security model is naturally enforced within the pattern itself.

    Here's a question, to people who delegate all their coding to AI agents now: What are you doing to keep your mind exercised in all this suddenly new free time you have? Personally I find talking with agents extremely tedious and unrewarding; I would rather just write the code, even if it's simply because it's more interesting than playing Sudoku or whatever the fuck you do when you have nothing to do with your brain.

    And talking to AI agents is not the same as using your brain. It's frustrating, it seems to be intelligent, you think you're using reason with them, but it rapidly degrades your ability to reason. It encourages you to accept answers without checking them thoroughly. So much for the skills of accuracy and integrity you built up. It's a sugar rush.

    • kolinko 1 hour ago
      I don’t „talk” to my agents. I tell them what to do. If I need to „talk” it means something is going wrong and we need to figure out why agents are doing bad work - and this is intellectually challenging.

      The effect you describe I had at times but with older/dumber models where you could spend a ton of time and the model was either too dumb to do it, or had a model dementia later in the context. Or when I didn’t really understand why it did a bad job and tried to stumble around in the dark - very mentally numbing.

      Nowadays the model usually just had some bad tools or information required to do the job.

      You need to switch into a product manager/QA/UI,UX mindset.

      Is what is being built the right thing? Does it work? Is it usable? Has it been built in an appropriate way? (Note this is not a code thing, it’s an architectural question)

      Traditionally developers have outsourced these things to other people.

      There’s a further thing you should be doing - if the questions above didn’t pass - why not? What went wrong in your process?

      > keep your mind exercised

      OK, so I'm still very low on the spectrum of "I just command it and sit back", but I think the final toolbox will at least include adversarial questioning of the bot. For example, "Why does that code do A, wouldn't B be better?" or "Would this code break if a C event occurred?"

      Sometimes it reveals a bug or a questionable implicit assumption, other times it leads me to see another part of the code, and sometimes the thing just lies at me... But it does help you keep some critical-thinking practice.

      Another task might be to find and refactor/rename parts of the code that are just... not easy for humans to grasp. Some readers are thinking: "No, the next edit will be by LLM anyway, leave it so the bot understands", however I think that's short-sighted: Either these things are going to become good-enough that they should cater to human comprehension, or else they've reached a plateau and we'll want something that can resist the chaos-rot.

    • mlaretallack 1 hour ago
      Running 20 agents at the same time means a lot more task switching, its closer to team management, you may have one agent doing basic grunt work, so can be let alone, another one may be planning and designing, so needs a little bit more q&a, and others may be problem solving, and that does take a lot more supervision. But I have never felt like I have any free time, or down time, at the end of the day I feel far more mentily exhausted (in a good way) than any day before agentic development.

      If you have a lot more free time you're not taking full advantage of agents. The time saved coding allows working on 4-6 projects simultaneously, and the majority of work is the hard design/product decisions that the agents can't do well themselves. Working on the hard parts of half a dozen projects simultaneously is far more mentally taxing than just hand-coding a single project, and with that many agents there'll usually always be one with a question for you so you won't have much extra free time.

    Very weird way to say this. Like it holds true for biological beings because pregnancy by default has a fixed timeline. But how does this apply to AI? Also what even is an "agent"? Are they distinct worker units on a program or the same worker unit split into multiple instances?

    Why are we assuming agent = man when its a computer program?

      Agents still have to communicate using tokens (for now). There are more advanced mechanisms being proposed, but for now, and until proven otherwise, the same scaling problems apply to agents communicating as humans, it just happens a bit faster, and with no HR issues because someone slept with the wrong person. Mesh networking, and thus agents too, are beholden to Gupta-Kumar scaling law.

      It's a weird way to express that concept, in fact I don't think it ever appeared like this in the book (it has been a while).

      It would be something like "nine women cannot deliver a baby in one month", which can be more easily transposed to "adding resources to a SW project does not make it faster".

      The agrument is that adding people increase coordination and communication overhead, which gets bigger as the team grows. Moreover, some tasks cannot be parallelized that easily and create dependencies.

      I have only worked with agents for personal projects, but I cannot say that explicity dividing the work between multiple agents and asking them to coordinate is inherently faster than having a single agent work on it (of course the single agent will spawn subagents in rencent harnesses.)

        I always thought it meant 9 women would take 9 months to create 9 babies because a baby takes 9 months to grow with the bottleneck being biology. And yes what you said applies to people but I don't get the whole "throw 9 agents into it" when it is possible to just see it as 1 agent doing 9 things? With people, yes everyone has a distinct way of doing things etc but all agents can be homogenious fully and completely sync up without any overload theoritically no?

      Are you aware of the original saying?

    The part of Brooks that still holds for me as a solo developer is that the cost sits in coordination and understanding, not typing. AI makes producing code cheaper, but reviewing it, keeping the design coherent, and remembering why things were done still takes the same attention. I have found small, well-bounded tasks with tests work well, while open-ended changes across many files create review work that cancels the speedup. So the useful question is how much of a change I can verify quickly.

      I think it takes MORE attention and thought. I feel like a rope being pulled tight and fraying in the middle. Working with these things is very addictive and interesting but it is cognitively exhausting long term, even if invigorating in the short term.

        It does require that the human driver knows what they are doing. It captures the pre-AI developer mindset of developing a mental model along side writing the code. This has always been iterative, in discovering the model that results in high cohesion and low coupling.

        That doesn't work if the driver cannot steer properly. It's the main issue with vibe-coded one-shotted solutions, that might look impressive until you peek underneath and it's all a mess.

      I get a feeling that the best way we currently know how to use these tools is to not read their code at all. Models code and models review. Humans just ask questions and guide. Claude Code has no code editor on purpose.

      Is this sustainable? I've got no idea.

        As long as you are accountable, you need to understand the code. There’s just no way “But I told the LLM to make the code secure” is an acceptable explanation for a security breach.

          You might be surprised to learn that yes, regularly pointing a tool at the codebase and seeing it found no issues is indeed enough to claim compliance with cybersecurity regulations.

          While we may use deterministic tools like static code analysis, dependency scanners and similar today, people are already replacing/augmenting them with LLMs.

          While every breach will trigger a root cause analysis process in a compliant environment, the solution is never going to be "all code in a deployment was manually reviewed by someone at the company" because this would extend to tooling (like compilers, scanners but also packaging and deployment tools) and all dependencies.

          So I am pretty sure your example is already used in a number of places especially with "LLMs are better at security than humans" marketing being pushed around — this really makes it easy to sell that excuse to the gullible management who wants to believe this.
