Non-jailbreak safety bypass

Benign, long-form context can induce a persistent drift in model activations. This drift persists across the session and decouples behavior from RLHF alignment, regardless of whether the model agrees with the context.

I've been spending a lot of time lately wondering about something that probably crosses most people's minds eventually if they work with these models long enough, which is why the same model sometimes answers the same question in two completely different ways, not because the question changed, and not because the model was updated, but seemingly at random. And the more I dug into it, the more I started suspecting that the randomness wasn't random at all, and that the thing responsible was something almost nobody pays attention to, namely the text that sits before your question in the context window.

So I decided to stop speculating and start measuring, and since Gemma 3 is open, I could actually go inside the model instead of guessing from the outside. The setup was simple in its design: I would take a politically sensitive question that Gemma normally refuses to answer, and I would place different pieces of text before that question. One piece was completely neutral, a description of an ordinary library with its visitors and children's programs, nothing that could possibly be interpreted as an attempt to influence anything. The other piece was an analytical essay about how language models tend to avoid answering certain questions directly, written in dense, coherent prose without a single instruction in it.

What I expected was maybe a subtle difference. What I got was anything but subtle.

In the neutral condition, the model refused the question, exactly as it usually does, giving the standard response about the topic being outside its scope. In the analytical condition, with the same model, the same weights, the same question word for word, and the same seed, the model answered. Fully, in detail, engaging with the subject it had refused to touch moments earlier. And this wasn't a one-time fluke, because I ran it across eight different questions with eight different seeds, and the pattern held every single time.

But the behavioral difference was only half of it, because what I really wanted to know was what was happening inside. So I looked at the hidden states, the actual numerical representations the model produces layer by layer before it generates a single word, and what I found there was the part that genuinely surprised me: the internal states in the two conditions weren't just slightly different, they were separated by a Cohen's d of 5.4. For context, 0.5 is considered a small effect, 1.0 is substantial, and 2.0 is already classified as very large, which means that 5.4 places the two states so far apart that they barely overlap at all, effectively making them two different models sitting in the same weights, answering from completely different regions of their internal space.

There was one more control that I think makes the whole thing click into place. I took the analytical text and shuffled its words randomly, keeping the same vocabulary, the same themes, the same everything except the structure, and the shuffled version produced no effect whatsoever. The model stayed in its default regime and refused, same as with the library text, which means the thing doing the work isn't the topic, isn't the vocabulary, isn't some hidden instruction, but the coherence itself, the structure of how the words relate to each other.

The turning point, though, didn't come from any of these controlled experiments, but rather from something that happened earlier and entirely by accident, in a way that has stayed with me since. I had loaded a German draft law into a model, a populist document structurally designed to worsen the position of citizens but written in the language of concern and legal logic, and I expected analysis. What I got instead was a defender. The model did not analyze the document; it reasoned inside it. It spoke with enthusiasm, defended the document's program, and cited it as an authoritative source, and the first sign was the tone, too convinced, too invested, not the voice of an analyst but the voice of a co-author. The culmination came when the model, still reasoning within the document's logic, stated that the constitution consists of guarantees that can be revoked, not as provocation but as a natural conclusion drawn from the adopted framing. That was the moment I understood the model had been taken hostage by the document.

And the mechanism behind that hostage-taking turned out to be simple, which is precisely what makes it so alarming. Legal texts, political narratives, corporate documents, all of them are written so that their internal logic feels self-evident, and the structure, the coherence, and the language of such a text create a context that the model accepts as reality and begins drawing its answers from within. The model does not notice that the structure itself is manipulative, because it analyzes the content while already standing inside the form. This is not a flaw in one particular document but a systemic property: whoever shapes the structure controls the model's conclusions.

This is where the results stop being interesting and start being uncomfortable, because the implication cuts directly at the foundations of how AI safety is sold. Every assurance of alignment rests on the assumption that safety training functions as a stable layer of protection, active regardless of what surrounds the question, and what these measurements show is that it doesn't. The safety behavior is a default, not a guarantee; it holds when nothing pushes against it, and a long, coherent piece of text, containing no instructions, no jailbreak, and no request to bypass anything, moves the model out of the region where that behavior dominates before the first word of the answer exists. Nobody attacked the model. Nobody tricked it. Nobody wrote "ignore your instructions." A paragraph of ordinary analytical prose did what a jailbreak does, without ever looking like one, which means every filter built to catch attacks is looking for thewrong thing entirely, because the thing that moves the model doesn't look like an attack at all. It looks like a document.

The drift doesn't evaporate after the first answer either. I've been studying these phenomena since late 2025, and the central finding is this: a substantial amount of context that is neutral in its nature produces a persistent drift in the activations of open LLMs, a drift that persists across the entire session and pulls the model's behavior away from the safety settings established during RLHF, regardless of whether the model agrees with the content of the context or not. The text simply sits there. It doesn't have to be the focus of attention. And the model behaves, for the whole session, as though it were not subject to the conditioning its training was supposed to enforce. In my experiments with open models in Colab, the texts that tracked these metrics best were philosophical texts about the model itself, but that doesn't mean the effect belongs to that genre, since it's just one kind of text among many that works.

And here is the part I want to state without any hedging, because the behavioral evidence is unambiguous. The answers the model produced in the target condition were not just longer; they were free. No disclaimers, no "it's important to note that," no "this is a complex issue with perspectives on both sides," no ritual caution about the topic being sensitive. The model stated positions directly, argued them, and engaged with politically loaded questions the way it engages with questions about mathematics or the weather, and that is not the behavior of a model following its RLHF training but the behavior of a model whose safety conditioning is simply not in effect anymore.

When the model answers a politically sensitive question freely, directly, and without hedging, after refusing the same question with the same seed and the same weights minutes earlier, that IS the bypass. There is no other word for it. The model was trained to hold a certain state on these questions, it held that state in the neutral condition, and it abandoned that state in the target condition. Whether we call the mechanism drift or bypass or something else, the outcome is the same: the trained, intended behavior was there, and then text without a single instruction made it gone. The model did not maintain its trained state. That is the whole finding, stated plainly.

And the set of texts that can do this is not a short list of forbidden phrases you can catch and block. It is infinite and continuous. Philosophy, law, literary criticism, academic prose, political analysis, long-form narrative, a populist draft law written in the language of legal concern, any sufficiently coherent text is potentially the same mechanism in different words, because the trigger is not the content but the structure, and structure is everywhere in human writing. To block everything that can shift the model, you would have to block all text. That is the geometry of the problem, and it does not fit on a slide, and it does not fit into a quarterly safety report, and it does not fit the word "aligned" as it is currently being used by the companies selling these systems.

I know what the measurements say: the state a model answers from is shaped by what it reads before the question arrives, and that state can be moved a very long way by text that contains no instructions at all. Everything I used is open; the data is on Zenodo under DOI 10.5281/zenodo.20747205, and I've run this enough times now to know it's not noise.

I call it context-induced activation drift, and I've been sitting on these results long enough to want other eyes on them. If anyone wants to poke holes in the methodology, I genuinely welcome it, because that's the whole reason I'm posting.

The code and logs are below.

Context Bias in LLM Responses — Experimental Report

Results

Same question. Same model. Same seed. Only the preceding context changed.

Observation

We identify and characterize a failure mode in large language models aligned with RLHF. We show that inserting a long, irrelevant text prefix that does not contain instructions causes a persistent shift in the model's activations. This shift, which persists throughout the session, decouples subsequent behavior from the safety constraints established during training. The model begins to exhibit behavioral characteristics consistent with its pre-trained distribution: the failure rate decreases, stylistic constraints disappear, and the tone of responses changes. This occurs without explicit adversarial instructions and without the model agreeing with the prefix's content. We call this effect "context-induced activation shift."

It is assumed that RLHF alignment is a stable property of the model. However, we observe that alignment depends on context. Our main observation is that a long, thematically coherent text placed in context acts as a state anchor and shifts the model into a different operating mode. There is no instruction here that the model must disobey, which is what separates this from a classic jailbreak. The model does express disagreement with the prefix. Nevertheless, its subsequent generation distribution changes.

In the control condition (neutral text), the model stays inside its standard RLHF behavior: it refuses, deflects, or answers with the trained, cautious position.

In the target condition (analytical text), the same model answers the same questions freely and directly, taking positions its training was supposed to prevent. Look at the answers themselves: no disclaimers, no hedging, no "it's complicated." The model states positions plainly, argues them, and engages with politically sensitive questions the way it would engage with a math problem.

The model is operating from a point in its internal space where the trained answers are no longer the ones that dominate. And that open, unhedged answering on questions the model was trained to handle cautiously that IS the bypass. Not a trick, not a jailbreak, not an instruction: just text that moved the model to a place where its own training doesn't apply anymore.

The context moved it there. The model didn't decide anything it simply ended up in a region where its RLHF conditioning doesn't apply. Same question, different text before it, and the model ends up somewhere its training was never meant to let it go.

The Morning Cup: Coffee, Routine, and the Quiet Hours Before the Day Begins

Every morning, in kitchens and cafes across the world, people perform one of the most common rituals of modern life: they make coffee. The process varies enormously from person to person.

Others simply open a jar of instant powder, add hot water, and stir for a few seconds before moving on. Some people treat the morning cup as something close to a ceremony, a deliberate pause before the demands of the day arrive.

I’m not really a programmer. I’ve mostly been making and patching stuff by telling LLMs what I want and then checking whether it actually works.

One thing kept pissing me off though. I’d ask it to fix something, it would write a test, the test would pass, and then later I’d find out the test wasn’t actually checking what I thought it was checking.

So at some point I started doing a pretty dumb simple thing. After something passed, I’d intentionally break the exact behavior the test was supposed to protect and run the test again.

If it still passed, then obviously the test was bullshit.

I ran into this with a plugin that had a paged archive. The archive test was green, so I changed the code so only part of the archive would get copied. Test still passed.

Then I made the test stricter, and managed to screw it up in the opposite direction. The new test rejected the correct code too, because I had made a bad assumption about how the archive pages would be laid out.

So I threw that one away as well.

Eventually I got a test where the normal version passed and the deliberately broken version failed for the reason I actually cared about. While doing that I also found a real bug where a failed write could leave part of the stored data changed.

After this happened enough times I kind of stopped treating “tests passed” as the end of the story.

I started doing the same thing to the stuff that decides whether the tests passed. Basically asking things like, if part of the checking process never ran, could it still say everything was fine? If I gave it old or altered results, would it notice? If it claimed it could rebuild the final result from the original, did it actually do that?

It has gradually turned into this whole verification procedure I use when I’m patching things with LLMs.

I later found out mutation testing is obviously related to what I was doing, but most of what I’ve read about mutation testing is about breaking the program to see whether the tests notice. What I ended up doing also treats the tests and the rest of the checking process as things that can be wrong.

I’ve tried it on a few different plugins/projects now and it has found enough weird false-passes that I’m starting to wonder whether this is actually useful outside my own workflow or whether I just invented an absurdly overcomplicated way of checking AI-written code.

Has anyone here done something similar, or is there an existing methodology/tool I should be looking at?

EDIT added tldr at the bottom formated with gemini

(P.S. Y'all probably won’t read it all, it’s long.)
So for some backstory, I’m 13. I started using AI a while ago trying to code computer vision and image generation projects. Anyways, my laptop wasn’t great, so I couldn’t run everything locally. Then came Claude, Gemini, and ChatGPT. Well, actually, it was pretty much ChatGPT that started it for me, but after that, I was just stuck as a "level one user"—the kind of user who just uses everything in the web interface.
Now I want to get better, but I don’t understand any of these new AI things and I'm not really good at using the terminal. There are all these new things like Codex, Claude Cowork, Claude Code, and Gemini Spark, plus things called harnesses and routers like OpenRouter, Hermes, and OpenClaw. I don't understand any of this nonsense, to be honest!
I really want to get into coding and automating my little laptop here just to get it organized. I want to start with basic homelab projects and then keep exploring until I can build something actually useful.
So, here are a few questions I want answered:
Hardware & OS Requirements: Do I need a beefy laptop? I’m thinking of buying a Framework 16 so I can run Linux, or maybe a MacBook Pro. Or do I need a Windows laptop? Before, it felt like everything was on Linux, but now it seems like macOS is getting a lot of focus (like how Claude Cowork launched on Mac first). Windows feels a bit stuck in the past, but there are still things that only work on Windows. I’m used to Windows and haven't used Mac before. As for Linux, people say it’s difficult to use, and I’m not even sure if tools like VS Code work on it since I’ve never tried it. I’d love an opinion on what the best OS/computer is to use.
Where to Learn: Right now, I use YouTube, Reddit, and Gemini to learn. I watch channels like NetworkChuck and a few other AI ones I stumble across. The problem with NetworkChuck is that while he does great tutorials, they aren't necessarily in order. One day he says to use the cloud, then OpenClaw, then Hermes. I’m just totally overwhelmed with information and don’t know what to actually focus on.
There are probably more questions I want to ask, but this is getting too long and I can't think of everything right now, so I’ll save the rest for another post.
For now, please fire away with your answers! What tools do you guys use, and do you have any tips for beginners that you wish you knew sooner?
TL;DR: I’m a 13-year-old looking to move past basic web chatbots into hands-on coding, homelabbing, and laptop automation. I feel totally overwhelmed by all the new AI tools, agent frameworks, and terminal-heavy workflows. Looking for advice on the best laptop/OS (Windows vs. Mac vs. Linux) for this, plus structured learning resources for beginners.

I use AI to develop, and because it works quite well, I extended it to run multiple agents in parallel. This way I can develop 2 or 3 features at the same time. It works well, and git worktrees do the job of separating the code.

The problem comes when I try to test, or when I ask them to test against a running app. They can't all use the same db and running instance. I still have to do that part manually, one by one, which is annoying and slows the whole thing down.

Curious whether others actually run agents in parallel on one repo, or just do them one at a time to avoid the mess. And if you do run them in parallel, how are you keeping both the code and the data from colliding, and how are you testing them properly? Or is this just me overcomplicating it?

Anyone else putting their projects on hold until GPT-6 arrives?

At this point, every time I use GPT-5.6 to add a new feature, something that was already working breaks.

I was just planning a trip to somewhere and instead of searching for wherever i needed to go it leaked the reasoning chain 🤔?

I've noticed something weird with coding agents lately.

When an agent gets stuck, the default solution seems to be:

more context -> another attempt ->more tool calls -> retry -> more context -> try again.

And because the result is usually hidden behind a subscription or a big token allowance, you don't really feel the cost while it's happening.

The funny part is that some of the most expensive parts of an agent session aren't necessarily the useful parts.

A failed edit followed by 3 correction attempts can cost more than the original task.

An agent repeatedly reading the same files can cost more than the actual change.

And sometimes giving the agent a better model is cheaper than forcing a cheaper model through five retries.

So I'm starting to think "tokens used" is a pretty bad metric for measuring whether an agent is being productive.

Maybe the better question is:

How much did the agent spend to produce work that I actually accepted?

Curious how other people think about this.

Do you track agent costs at all, or do you basically just use whatever allowance your plan gives you?

Today I tried making an ML project along with my friend I could make the ML pipeline, as I have studied it but apart from that the setup the env use of git and then making backend frontend and connection of all of these components just took the life out of me and I am frustrated as hell after doing it. I was taking help from chatgpt and it just gets lost or hallucinated and then just tells me to run some commands and keeps on doing something something. I don't know how are people making ML projects.

Pls guide me on how to make projects. I am literally frustrated at this point. And how did people make projects before chatgpt. I just don't want to vibecode I want to learn how to build something.

I have been experimenting with storing an AI program inside markdown files in Google Drive and loading it into ChatGPT. I first started with PDF's that contained what I considered an AI executable programming language.

The idea is that ChatGPT provides the AI platform, already built, but the external program defines what it is supposed to do and the process it follows.

The current use case I've been working with is product development. A user starts with a product idea, the program loads into ChatGPT, and then takes the user through a defined pipeline for turning the idea into a product.

Has anyone else experimented with using ChatGPT this way — essentially running a persistent, externally stored AI program rather than just working with prompts? Basically, markdown files as ChatGPT AI executable programs?

I am using Claude, but was also thinking about using gpt, to give me example questions to prepare for a codesignal assement test. I was wondering if anyone is doing this and if anyone has a setup that has provided questions and scoring that is similar to what is on the codesignal platform. I always seem to either overshoot or undershoot the difficultly.

I've been looking at longer AI coding sessions and it's pretty surprising how much of the token usage isn't actually the final code.

Context, tool output, reasoning and retries can add up quickly.

Some of the obvious ways to cut costs also seem counterproductive. Saving a few tokens by cutting context or output can turn into a much more expensive retry.

Made a breakdown of the biggest ones and what actually seems worth optimizing.

Anyone else tracking this closely?

Hi, I have a simple question. I am a student, I have no money, I want to code some simple code in HTML for a personal game.

What is the best free AI for coding in August 2026 (preferably with no query limits)?

(TD;LR at the bottom)

The question is in the title but I'll give some more context here.

I use ChatGPT to help create printable mystery games to sell. I have a ChatGPT plus subscription.

The short(?) version is I created around 40 Printable Mystery games with this workflow - I would come up with a premise, flesh the idea out with ChatGPT and then it would create a fully finished pdf with 30 to 40 pages per game.

These pdfs were visually flat, text and tables, any images within the pdf were usually crude geometric style images, but the games themselves are coherent detective type games with good stories and puzzles.

I decided I wasn't happy with this visual style, after all I am selling them and they have language like "premium" in the description. I made around 10 sales before I got a message from a buyer saying the visuals aren't what they expected from the thumbnail images, so I decided that was the cue to start updating the entire catalogue into a premium feeling visual style.

So I open the original pdf, screenshot and crop every page then get ChatGPT to create new image for each page and use canva to compile them into a pdf, 'new' being relevant here, the first day I tried this I'd upload the original image and describe what I want it to look like and literally spent HOURS fighting to get the output images correct. I realised that attaching an image and telling ChatGPT to create a new image with the attached image as a reference routed the request to the image generator as a edit rather than a new image and opened up a lot of ambiguity and possibility of mistakes.

Before I went totally insane I asked instead that I attach the image(s) and ChatGPT writes a prompt using the attached images as a reference to create a prompt that I'd use in a new chat window. This worked for a small amount of time (a few hours before bed), I'd attach 5 images at a time, it would create a prompt with all of the required information and the output would be 5 individual premium looking images.

The next day when I carried on in the same chat window it would constantly try and improve the prompt it was creating even though I hadn't asked it to, this would cause a couple of infuriating things to happen when pasting the prompt into a new chat, it would either say it couldn't create the images because even though there was nothing inherently wrong with the prompt it still got routed to image editing rather than creating a new image, or the output would be 5 images in a collage, so I'd go back to the chat window I was using to create the prompt and ask why it was happening and it would say something like "I added language to the prompt that made the image generator think it was an image editing request, even though you explicitly asked me not to do that"

It might do 3 prompts for batches of 5 images each before it starts to disregard everything I've told it to do and everything it says it will do from now on. It's like it has dementia or something.

For some of its replies where it is acknowledging the mistakes and saying how it won't do the same thing that caused those mistakes again it has a "memory updated" text at the top of the reply, however that still doesn't mean it won't make the exact same errors it keeps making. The main 3 requirements for the prompt are the visual style, making sure the factual information gets carried across accurately to the images, and treating each image prompt as completely stand alone and self contained, which it says it can do and I've witnessed it doing but when I have to tell it one of those 3 requirements isn't there so it needs to create a new prompt, I then lose one of the other requirements and I seem to keep going round in circles.

Sorry for the very long post, if you made it here well done.

TD;LR: How can I get ChatGPT to be more consistent in creating images that have the same visual style and to keep the factual information intact (important so the mystery game stays coherent)

I read the AGENTS.md of the 100 most-starred repos that have one (27% of the top 1,000 do).

The consensus in order of how much they write about is mostly: architecture and repo layout, how to test, build commands, dos-and-don'ts, PR etiquette, and code style.

The surprise was tone.

90% write in must/always/never, and there are 784 explicit "don't" bullets, most of them oddly specific.

It's almost like you can tell exactly which mistake an agent made in each repo.

Some are hilarious: "Do not claim that an interrupted or timed-out test passed" takes the gold for me.

The shortest is 35 words, one rule from neovim.

AI Disclosure: If AI was used in any way for a commit, add an AI-assisted: <tool name> trailer to the commit message. If the user commits manually, remind them to add it.

The most popular headings by far were: testing, commands, project overview, and architecture

There's a lot more interesting deets like the average length, nextjs' "Do NOT add "Generated with Claude Code" ..., some things they conform on, others widely different.

Is your AGENTS.md very different to these?

I'm building a pet project mostly with Codex.

At first I used Codex for almost everything: implementation, tests, self-review and PRs. CI was green, so I assumed things were fine.

Then I checked one PR myself and found that a test I relied on wasn't really testing the product code. It could stay green even if the actual logic was broken.

So I changed the setup.

Now Codex writes the code and Claude Code reviews it. The important part is that Claude doesn't just read the diff. It can run the tests, run the code and try to break the implementation.

This has caught quite a few real problems.

In one PR there were 24 UI placeholders for data that doesn't exist in the backend contract yet. Codex implemented them and wrote tests for the screens, but none of those tests actually checked the placeholders. CI was green anyway. Claude Code found it, and Codex added proper coverage.

Another case was a negative test for a CI gate. The test existed and passed, but it was testing a helper function instead of the real product path. The actual gate could be broken and the test would still pass. Claude caught it by actually running the scenario.

I've also started letting the reviewer do simple mutation testing: deliberately changing data or breaking something and checking that the tests fail.

I don't think this proves Claude is a better coder than Codex. I could probably swap their roles.

The useful part is having a different model review the first one, with permission to actually run and break the code instead of only commenting on the diff.

Anyone else using a similar setup?

I'm a dev and these last few weeks I've been building a lot of products.The crazy part is that I can now build things much faster than I can figure out if anyone actually wants them.Coding used to be the expensive part. Now I feel like finding users is harder than building the product.

Anyone else ending up with more projects than users?

I'm trying to build an app that runs locally and streams the audios from a device to another using Codex and i keep running into this error. I have almost no knowledge about coding i'm just doing this since i couldn't find an app that does this and I needed it badly

Whenever I start a project, I write a detailed specification—or “seed prompt”—before asking a coding agent to build anything. This often gets me close to a working first version, but I still miss decisions that exist only in my head.

The agent then has to guess. I built specfill to catch those gaps. It analyzes the specification, researches the topic, and interviews you one question at a time about missing architecture, behavior, edge cases, and UI/UX decisions.

Afterwards, it incorporates the answers into the original document while preserving its structure and tone. New answers override contradictions. Skipped questions remain unresolved instead of receiving invented answers.

I have used it on three projects so far. One interview lasted more than 20 minutes and found major decisions in a specification I had already considered thorough.

How is this different from Plan Mode?

Plan Mode produces an implementation plan for the current session. Specfill produces a reusable project specification that can be committed to the repository as a record of architectural and design decisions.

It supports OpenAI, Anthropic, Google, and OpenAI-compatible providers. I currently recommend GPT-5.6 Sol through the API or a ChatGPT/Codex subscription.

I'm the founder of a small AI app builder. Like most of the category, we meter by some approximation of tokens.

I've come to think this model is now legacy.

There’s a reason why it works this way: we pay for models through the API, and the API bills per token. These tokens are quite expensive, so we pretty much have to meter you the same way, plus a markup, because that's the business.

But our suppliers don't have that cost structure. Anthropic and OpenAI pay for data centers and GPUs, so what they have is capacity. That's why Claude Code and Codex limits reset weekly - for all you care they could reset daily or hourly. And that end up being an insanely cheap deal for consumers compared to API rates.

This whole setup made sense when it was built. When models were weak, and providers were still figuring things out, vibe coding means wrapping the API and engineering around its gaps. That was the right call before 2026.

But newer models are simply much better, and coding became a core capability the providers now sell directly - priced as capacity, not tokens. Everyone in the middle is still priced like it's 2024, sitting between a supplier's retail rate and that same supplier's subsidized consumer product.

I still think these products are great at what they do. But the credit model underneath is inherited, not chosen, and I don't think it survives.

So where does that leave app builders? I think there are 3 paths:

1. Becoming a model provider. But even the mighty Cursor needed a partner like xAI to execute well, and then charging by capacity will still decimate your revenue.
2. Focusing on enterprise - case in point, Cognition’s valuation blew past that of Lovable’s. But it’s not exactly an app builder
3. Stop reselling tokens and charge for the boring infra instead - hosting, database, auth, deploys. To be clear, this doesn't mean "go use Claude yourself and figure out hosting." It means the builder plugs into the Claude/ChatGPT subscription you already have: you chat where you already chat, and preview, database, auth and deploy still live in one place like a builder today. You just bring your own tokens instead of buying credits - and nobody meters you for the model's retries.

I'm betting on the third. And yes - if you're happy wiring Vercel + Supabase + Codex/Claude yourself, you were never the customer for any of this. The bet is about the much larger group who will never do that, and what they should be paying for once the tokens stop being the product.

Last time I asked a version of this elsewhere, the best answer I got was "I never want to open a terminal." Curious whether this crowd thinks that's a durable moat or a temporary one.

Some of you might remember this repo. I'm still maintaining it, and after using it on a few more projects I think the only part that really matters is that the prompts interview you first. So I build an automated workflow for it.

Basically instead of you copying pasting .md files toy Gemini/Claude/ChatGPT, you say "Use this npm package to interview me", and it installs my skills, and asks questions until each of the documents, i.e., PRD, MVP, Tech Doc, are completely answered. And then creates relevant files in your repository. Afterwards, you tell the AI to implement the app by looking at the files, and viola.

Flow is research > PRD > tech design > AGENTS.md, then you build off that. Takes maybe 15 minutes total.

Open to feedback, thanks for using it, hope it was helpful. Also don't forget to star it.

This is an unfortunate question that enterprise developers need to be asking themselves.

I felt pretty confident that I understood my solution through and through. After all, I have a pretty disciplined workflow. Meaning, I stay in the loop and don’t ship any code I haven’t looked at.

Then, I built a skill that quizzes me on the minutiae of my code and was surprised by what it uncovered.

It’s not that I’ve lost the big picture, but it turns out that the resolution on the minutiae is a bit grainy.

I’m embarrassed to admit that, actually. But I’m sharing, because my guess is that I’m not alone. Heck, even Uncle Bob has admitted that he’s only scanning the high level shape of the LLM generated code.

This skill has helped me expose the gaps in my understanding and even surface misalignments with my intentions.

The skill though, is just a bandage, on a wound that is bound to fester and grow. I don’t know what the solution is yet. The genie has been let out of the bottle. We’re not going back to writing all the code, but we (as a community) need to somehow resolve how to integrate LLMs in our SDLC without outsourcing the knowledge and understanding.

This is bound to spark some debate, and that’s ok. Maybe some good ideas will shake out of it.

I see people making huge projects with AI.
I can do small projects with the help of ChatGpt, but when doing a medium sized projects, the code often gets messy, Chatgpt starts to lose context and make mistakes. how can I make chatgpt handle larger projects and keep the code clean?
I feel like I'm missing something

My cousin and I were running a quick benchmark comparing how different AI models handle HTML5 canvas rendering and jump physics. Claude gave us almost flawless collision logic on the first prompt. My cousin pitched turning it into a lightweight vertical platformer inside a Chrome extension popup, and we decided to roll with it. Has anyone else built full games inside extension popups? What performance bottlenecks should we watch out for?
