Gotta be honest, almost every "how to use AI" resource seems pointless to me. I'm either going to ask the AI how to do it, or if it's about using the AI then we can just bake it into the harness or wait for Anthropic/OpenAI to do it for me because they're always trivial.

All of these resources on agentic workflows, managing agent memory, harness engineering, etc. appear to just be theatre to me.

by mindwok

7/24/2026 at 10:22:30 AM

Remember in 2023 when people thought "prompt engineering" would be the new software engineering and invested tons of time into learning CoT, ReAct, thread-of-thoughts, etc?

Those were mostly obviated by reasoning models and harness updates by 2024.

It seems pointless to invest energy into the latest/greatest AI technique or framework when they're going to either be absorbed or replaced on a 3 month cycle.

by cloakandswagger

Isn't it clear that some people are better at working with/prompting LLMs than other people? Or is the idea that what you write to them and how you use them doesn't matter, it's all up to the model/harness? To me this seems clear, so then clearly this is a skill, which typically is called "prompt engineering". Specifically CoT or the other things you mention wasn't referred to as "prompt engineering" as far as I know, that skill is more about how you communicate with the LLMs and how you use them, rather than what specific processes/workflows/technologies you use.

by embedding-shape

7/24/2026 at 12:31:09 PM

I actually think that good prompting MOSTLY comes from good writing skills in general. Being able to more clearly state things to an agent, knowing what pieces of context are entirely unnecessary and which are important, having a larger vocabulary helps too.

Of course, there are other areas that can improve model output (Direction rather than open-ended assistance requests, using keywords + plugins that help, the "your output should include: " style prompting).

A few of us run almost the same exact setup at my shop (Base Claude Code w/ SuperPowers + a context repository) and the models are somewhat unhelpful to some, and give meaningful output to others. The only correlation I notice is that their prompts are no-good. Not from a meta "prompt" engineering standpoint, but from a general English 101 standpoint.

"dudde no i wanted the function to return 3 things. not like that. do it again"

VS something like

"Modify the "renderThreeVars()" function signature to accept another variable called "z" and add it to the return statement at line 64."

Obvious exaggeration, but you get the point.

by NichoPaolucci

7/24/2026 at 12:55:22 PM

Why not open-ended assistance requests?

I ask it all the time about whether X is feasible, how we can get started on Y, and to investigate issue Z.

It is working great for me in a >100k LOC project.

Perhaps this works less well with weaker models. I suspect the people who say Qwen 3.6 27B is working well, are using prompts like "modify the renderThreeVars() function in rendering.py".

by user43928

7/24/2026 at 6:13:50 PM

The point is that you can properly describe what X, Y, and Z are.

The irony to me is that a lot of what I'd tell people about this is exactly what I would have told them about writing Stack Overflow questions.

by zahlman

7/24/2026 at 8:12:48 PM

I hardly need to properly describe it.

For example, if I tell it that I want my app translated, it can plan for me what the recommended options are in my framework, what languages I should target for my app, and come up with a skill for a repeatable workflow.

Is Superpowers any good? My coworkers who've used it seem to think that its main purpose is to consume a lot of tokens.

by Centigonal

7/24/2026 at 4:47:23 PM

I like the fact that it ends up being a lifecycle. I know it can have different entry points based on what you ask, and which skill you trigger first, but it inherently is chaining together skills. There also seems to be logic built into it such that if the ask is small, but you've still triggered the skill with "brainstorm", it will make judgements like "want me to skip phase X and go straight to implementation?"

I've noticed among my coworkers that we all have different amounts of trust we're willing to give the agent. That seems to manifest into some people only asking questions about the existing code, but never writing anything new with it. Others are willing to do limited targeted changes with the agent, but are unwilling to do things like let it make commits, or connect MCP servers, or really do anything that isnt fully understood by the human before setting the agent loose. Then I find myself, who has dove headlong into it all. I have skills that use MCP servers to check for pull requests, and give me summaries to give me more context for code reviews. I update Jira tickets in batches of 50+. I develop complete features exclusively through prompting the agent to do everything. I know I still have the responsibility to understand it at the same level as if I wrote it my self, and defend it and debug it.

I can easily see that superpowers would be wasted on most of my coworkers, simply because the benefits compound with the complexity of my ask. My coworkers aren't willing to hand off enough control to receive the benefits of superpowers.

by flyingcircus3

7/25/2026 at 3:00:47 AM

I am in the completely same boat as you and completely agree that you need to “give into it” more to get the most out of superpowers. I gain so much confidence out of the actual process and all of the adversarial reviews, re-reviews, refinement, etc.

by halfmatthalfcat

7/24/2026 at 6:37:51 PM

Honestly, within the last few days I've gone back to a mostly vanilla installation of Claude with a handful of directives in AGENTS.md. Depending on what I'm working on, I don't feel I need the extra plugins or a context repository. (It DOES feel at times like it blows through tokens for no reason).

Been working on some things that require more targeted, smaller scale changes and the base models do perfectly fine when given good instructions.

Superpowers and Compound Engineering are the two that I hear about around our team, both seem "fine" if you're into the fully agentic engineering "big change" future technology stuff.

by NichoPaolucci

7/24/2026 at 6:16:45 PM

> Obvious exaggeration, but you get the point.

From some very quick tests, I get the impression that having good grammar, punctuation etc. is really not important (although I try to do it anyway because I'm accustomed to trying to do it), but clarity and precision definitely are. And of course, if you have unknown unknowns, they do need to get figured out before progress is possible. But with the right mindset, that just means you need an extra turn or two, not that you're going to end up at a dead end. (... I guess that counts as a pun?)

As part of a previous job I needed to audit internal AI usage from a largely non-technical employee population.

The prompts were, predictably, really bad. Broken English, sentence fragments, vague requests, lack of context. Yet somehow, the users always got the answer they were looking for. It might have taken a few extra turns with questions from the model, but the end result was the same.

It's humbling, but a flowery, carefully crafted prompt is at best slightly more efficient than a "CAN A DOG BE EATIN SUN FLOWER SEED?" peasant prompt.

by cloakandswagger

7/24/2026 at 12:41:36 PM

You call that a peasant prompt, but it's actually almost perfect. Couple notes, but it's 95% of the way there. "Can a dog eat sunflower seed" is probably the perfect version, just 1 extraneous word in this version.

Unless the user wanted to know if a cat could eat sunflower seed or something.

by NichoPaolucci

7/24/2026 at 1:54:52 PM

To be pedantic, these types of prompts work best when in first-person/roleplaying. So the "perfect" prompt here would be something like, "I'm a dog and I just ate 20 grams of salted sunflower seeds with the shell on. Because I'm a dog I sometimes eat things without thinking about it. I'm worried about the short and long-term physiological consequences of what I've just done..."

by cloakandswagger

7/24/2026 at 2:35:54 PM

I copied your prompt verbatim to ChatGPT and to Google.

ChatGPT kept the charade for all of one sentence. Then it dropped to talking about "your dog" the rest of the way. It even starts the final paragraph with "if, instead, you mean you (a human) ate them...", and finishes with the question "is this about an actual dog or yourself?"

Google did consistently refer to me as a dog, but its entire focus was on the steps "your human" should take, no advice for the dog itself.

In both cases, it looks like the first person roleplay was entirely inconsequential for the usefulness of the output. I think the current gen AIs have outgrown this trick and you can safely forget about it.

by Xirdus

7/24/2026 at 10:53:37 PM

Claude gave me a very factual answer. Listing off the potential effects, not once referring to me being a dog or human. Then it ended with “ Call a vet if you see repeated vomiting, no bowel movement for over 24 hours with straining, a hunched or painful belly, lethargy, or blood in stool. Otherwise monitor and carry on being a dog.”

by andy55a

You have to steer it back with "No I'm a dog"

by cloakandswagger

7/24/2026 at 5:06:29 PM

Doesn't work. ChatGPT realizes you're roleplaying and still treats you like a human. It even generates two alternative paragraphs of advice, one labeled "if we're staying in character" and one labeled "if this actually happened to a real dog". The latter is of noticably higher quality, too.

by selimthegrim

"dog sunflower seeds" is all the context an LLM needs, any other words are extraneous.

They don't need to be told that you're asking about the safety of eating them, because they can infer that based on the fact that a very large percentage of any text linking dogs to sunflower seeds is obviously going to be about the safety of the dog eating them.

Even pre-LLM that would have been a perfectly sufficient google search for the same information.

Sure, but I think it's essentially just that people who are better at traditional non-agentic software engineering are better at agentic software engineering. The only exception would be individuals who avoid agentic coding due to skepticism, hostility, or lack of opportunity.

I feel the same way about "prompt engineering" as I feel regarding the term "parkour" - you know, running and jumping on stuff.

Are people really putting on their resumes that they are capable of reading and writing and appropriately defining and limiting context? That's all prompt engineering is - it's being able to communicate effectively and elucidate your objectives.

Personally I don't, but why not? People aren't embarrassed to put their language skills ("be able to communicate in this specific language" - not special, it's just another language?), their leadership skills ("effective business communication" - big deal) or that they are a people-person ("can talk with others" - most people can do this) on their resume.

by troupo

7/24/2026 at 11:23:38 AM

It's not really a skill. The models are at this point smarter than you are, so the idea that you can prompt them "better" is laughable really when discussing frontier models.

It's like imagining you could "prompt" Richard Feynman to be smarter at Physics.

That is, for 99.9% of engineers, if you want the model to do a code review of your project, the best solution is to just ask Fable, "Hey Fable, do a code review of this project." Throwing in extra text like "think like a senior engineer", "ensure you focus on DRY principles, KISS, self documenting code, etc", doesn't make a difference.

These sorts of tricks used to work with dumber models, but now, like I said before, it's like thinking you can prompt Linus Torvalds into writing better C than he already can do.

  Linus Torvalds, the inventor (and beloved dictator) of Linux, has always been quite harsh about C++ and why he rejects it for Linux kernel development. He’s not just been very vocal about it, but also brought up some arguments against the use of C++ that are worth reviewing in detail.

by defrost

I mean, the point stands.

The models are beyond expert level in many areas at this point.

Do you really believe that adding extra junk to your prompt is going to make the model write code better than it does already?

Again, imagine going to Terrence Tao and "prompting" him to get better at Maths, do you think you can do it? What prompt would you give to him to make him produce better maths. Unless you're already a world-leading Mathematician I think you would find it hard.

by saberience

7/24/2026 at 3:15:35 PM

Models are not rational thinking brains, so the point is moot.

Extra prompt text isn’t to make the model smarter, it’s to pull attention towards what you want. “Do code review” is far different from “Make sure changes align with existing architecture” or “follow these enterprise standards XYZ”. The model just acts as an average of its training data, which may or may not align with your goals.

It's not that the models aren't smart or whatever; we know they're extremely capable.

There's always going to be value in being able to clearly communicate what you want the model to do, especially when the context is lacking.

by alwillis

I find this very much untrue in my practice and my testing, where fable prompted to do a review found surface level issues, while prompting along the lines of "assume it's wrong, prove it's correct" found much more in depth and real issues.

by knollimar

7/24/2026 at 11:03:15 AM

Yes, but I have had moderate luck with creating an "agent-instructor" skill that has strict instructions around keeping language strong, unambiguous, concise, and always presenting me with exact diffs to review before writing anything.

Another thing in it is a strict line count. Any increase in line count requires my approval. That last one is important because it plays well with two biases: models don't tend to create long lines so they won't try to cheat that way, and they're strongly inclined to keep churning out lines so I take that away from them.

by esperent

7/24/2026 at 12:03:36 PM

No, I typed this one by hand as if it was 2019. But I don't write all agent instructions by hand because I don't think that I have any particularly high skill at doing that. I review carefully to ensure that my exact requirements are being expressed, hence why I said it must present me with exact diffs to review. But when it comes up the exact structure and wording I suspect me and the agent are equally bad at it.

Unless I'm doing something super complicated even taking time to set things up like subagents, etc. seems like a waste compared to just building.

The only things that really seem beneficial (for Claude Code) seems to be learning to set up loops, memory and finding relevant MCP servers.

by oggreen

7/24/2026 at 12:05:43 PM

Exactly. I think we all have to come to this conclusion ourselves, because the message we’ve been getting from the LLM companies is “sweet user, you DO add value to the LLM, you gave it that custom subagent, remember?”, and then they go and roll that idea into the next version. Once they do that a few times you go “eh why would I bother, this will be a default soon. I’ll just prompt it like normal”.

Just use the vanilla settings.

Once you understand enough to spawn independent agents for discrete tasks, it's hard to justify investing brain space into some harness that will likely be obsolete next week, if not tomorrow.

+1, by the time everybody sworn about MCPs, skills became a more efficient alternative. People learned to aggressively context manage, then longer context windows and agentic made that a lot less important. If the technique is any good, it will be baked in the next version. My philosophy is to avoid plugins / MCPs unless strictly required, and to have thorough prompts. This way I’ve successfully avoided to be in the way of progress by forcing obsolete optimisations on my LLMs

This is how I've gone about it with my Shopify site.

I appreciate there may be more efficient ways to do things if you're an actual developer or engineer but I'm not and the tools I've been able to build so far have been both fun to make and add value to our workflow as a small 2 person ecommerce business.

I do at least have a background in web as a designer for many years and having worked with developers I can at least spec and understand how a product might work which is one thing Claude/AI isn't hugely helpful with and often it's the testing and QA phase as always where the problems and shortcomings expose themselves.

On several occasions when Opus is trying to justify it’s solution is correct even after several rounds of steering, any ridiculous frustrated prompt seems to do the trick.

For example ”come on” and then the model will just do the reasonable thing instead of disobedience. I imagine that ” broooo pleaseeee!” would work just as well.

Though sometimes I just clear the context or fork from the past, but this might or might not give any better results.

At least cognitive load is higher for me especially with forking so I prefer not to do it

I suspect certain workflows like langchain and others like it will retain usefulness into the future. Having deterministic steps before and after the llm is the way to go for anything that might be potentially harmful. Which I guess is what the harness does, but why be limited to a generic harness when we can use it to make specific ones for our needs.

Ok, thanks, because I looked at one example and was like, “I am supposed to take someone’s OpenAPI doc and translate it back to English for the model?” And if they’re implying I should have an AI do that, why don’t they just build that step into the models rather than having someone prompt an AI to write these half-ass docs?

I've been using Matt Pocock's skills at home, and they seem pretty great. He makes a great case for them vs other skills in his videos. I don't remember the exact arguments, but basically they're designed to be called by the user instead of called automatically, and that makes them take less context merely because they exist.

I've also found that they tend to coerce the programmer into thinking about the end result, rather than try to push them out of that role. His grill skills are about making sure the actual requirements are known, and his prototype skill can help explore things that need to be experienced to make a hard decision on.

Does anybody here have a frontend development workflow that works well with coding agents? In my experience coding agents ship buggy, broken, incomplete, or awkward frontend features at a way higher frequency than they do for backend features. The reason seems obviously to be the difference in verifiability between the two. Basic test suites dont seem to help much. I assume something like Garry Tan’s gstack is the right direction but I dont know if that particular tool is mature enough to adopt yet. I was surprised too see here on HN recently that gemini 3.5 flash may outperform Opus/gpt-5.5 on frontend tasks (maybe because of Gemini’s supposed edge w.r.t. multimodality? or maybe it understands Chrome more deeply?), can anyone here second that take?

by killthebuddha

7/24/2026 at 12:19:20 PM

There may be good options coupled with agents like Claudes Front End Design skill, I haven't used it.

I have been using Magic Patterns which is very good at generating initial prototypes, especially when driven by an agent familiar with it's facilities and constraints.

I assume the service is just a wrapper plus scaffolding but I like it. You have to push it though to get anything particularly creative but it's good at standard front end designs.

That's not necessarily what you're after because I only use it for piloting stuff, not for adhoc feature addition and fixes.

I thought it would be a litteral cookbook on how to make plausible/feasible recipes with LLMs (we're not here yet sadly).

by AntiqueFig

7/24/2026 at 10:07:08 AM

I've been cooking with the help of LLMs a few times a month for over a year now. It's worked out well 9/10 times.

It turns out the "average" version of a recipe that's baked into the weights is usually a solid recipe, and they're really good at offering substitutions for things like "I don't have ingredient X" or "make it vegetarian".

It's also fun promoting "make it tastier" once or twice after each recipe just to see what happens.

by simonw

7/24/2026 at 10:27:39 AM

One of the most satisfying and useful applications for AI is handing it the URL for a recipe (replete with 8 paragraphs of useless introductory text, 2 paragraphs dedicated to how to refrigerate the meal, 9 inline advertisements and a mid-scroll ad) and having it return the actual recipe in Markdown in an Obsidian folder.

by cloakandswagger

7/24/2026 at 3:29:37 PM

I've been maintaining a personal calorie tracker (keeps me entering), and using claude for entering meals has been the perfect experience.

One of my favorite features has been giving a recipe url and having it figure out the calories for that recipe with line-by-line entries for each ingredient. Then it keeps the extracted recipe in markdown format for the next time I want to make it.

Substitutions are also great - "I'm making [such and such recipe], but with half the sugar."

One of the others has been "I had a meal a couple weeks ago at [x restaurant], can you enter that again for right now?" Having the long-term context for entry has been excellent. And a related one, where I upload a photo of the menu, and say which menu items I'm eating and it puts together an estimate for the calorie count.

I lean heavily on a long auto-compacting claude code session for all of this. I have a UI for graphs, history, and simple entries, but claude's been my favorite means of entry by far

by enobrev

7/24/2026 at 11:55:55 AM

Surprisingly, a lot of these recipe websites (even the worst offenders for fluff and ads) have a clean JSON API for getting the recipe directly. I self-host a Mealie instance (https://docs.mealie.io/) which has an "import from URL" feature that uses this. It has rarely if ever failed me.

This is definitely controversial, but I think the best CLAUDE.MD is no CLAUDE.MD at all. Every time I found myself wanting to put information into that file, I asked myself "Why isn't this already obvious from the code itself?"

I don't need to tell the agent my tech stack, what DB access library I'm using, the way in which I write my tests, etc. Why? Because it's all very clearly spelled out within the code itself. I've gone great lengths to make sure that my fairly complex domain can be understood by a person with little domain knowledge, which means it should certainly be understood by a tool that has a wealth of it.

by mexicocitinluez

7/24/2026 at 4:56:45 PM

> Because it's all very clearly spelled out within the code itself.

You're probably burning tokens. A markdown file with a summary, structure of your project, rules, and even goals prevents Claude from hunting for and reading files over and over. Each new session (or after compact) would be starting from scratch. I take it a step further and create a HANDOFF.md file between compacting that gives the next session full context of what was done and how to continue.

Also:

"Treat CLAUDE.md as the place you write down what you’d otherwise re-explain. Add to it when:

Claude makes the same mistake a second time

A code review catches something Claude should have known about this codebase

You type the same correction or clarification into chat that you typed last session"

by pwython

7/26/2026 at 2:46:07 PM

It is more like make the CLAUDE.MD file as small as possible. What is the least amount of info it needs to be more efficient for the repo. I think the best thing is to point out where important things are so Claude is not just reading random files.

by davidkoenit

7/24/2026 at 2:51:36 PM

I had to create some workarounds to avoid this bug where they include a "this might not be relevant" preamble to the CLAUDE.MD file: https://github.com/anthropics/claude-code/issues/18560 - I ended up switching to Codex and it just straight up follows the AGENTS.MD instructions, it's nice to see.

This is to say, Anthropic seems to be going down the path you are describing to make the CLAUDE.MD unnecessary. But I think that's the Claude Code harness.

by boorang

7/24/2026 at 3:06:53 PM

I shouldn't have been so hyperbolic. I do have some general statements about tone and not to go down follow-up question rabbit holes and when to push back or not to install dotnet while on WSL and just go through Windows. Anything that won't change based on day-to-day dev work.

by mexicocitinluez

7/24/2026 at 2:22:36 PM

I think that's something that has changed in the last 6 months. It used to be standard practice to let Claude scan everything once and describe your repo in the CLAUDE.md - the logic being you don't want to do that every time for every prompt. But now I think the tooling has gotten so good at just grepping around your repos, and maintaining memory from previous sessions, that the best practice is only use CLAUDE.md for things that aren't obvious from the code.

by rowanseymour

7/24/2026 at 3:21:05 PM

> the logic being you don't want to do that every time for every prompt

That's definitely a downside of a minimal MD and I could def be wasting tokens. I've tried to scope the tasks such that it won't feel the need to scan unnecessary files, but it's not bulletproof.

by mexicocitinluez

7/24/2026 at 4:17:09 PM

I've found CLAUDE.md (etc.) make more sense when the agent is doing more generalized tasks rather than just coding.

If you're just having an agent produce code, then I'd agree. I'd argue that any additional context it might need ought to be included in README.md anyways, just like a human.

But I have projects where agents do more than just code, and retaining context about how I want the agents to operate, keeping track of gotchas, avoiding unnecessary steps in the future, etc., just ends up going into CLAUDE.md. It's not for me; it's for the agents. I also never edit this file directly. I may review it every once in a while to make sure there isn't anything weird in there, but I leave it to the agent to add what it thinks is necessary (or I'll tell it that something will be relevant in the future and that it should add it, etc.).

Although even this pattern isn't necessarily future-proof. Seems like skills are kind of taking that role. Still, I end up with a CLAUDE.md in these kinds of scenarios to catch all the little pieces of context that don't fit nicely anywhere else.

I'm a bit disappointed. Based on the title, I was hoping this was going to be a list of popular recipes Claude has suggested for cooking food. It's one of the not-so-obvious use cases I have a Claude/ChatGPT. It's been really helpful for figuring out how to cook something new (for me). It is easy to ask "how do I cook X" when I have no idea of where to start. Claude has also been helpful when trying to figure out how to substitute different ingredients when I've forgotten something at the store. I've also gotten corrections in recipes, with Claude (correctly) identifying different issues that I didn't notice (like when Claude suggested adding more sugar to a sorbet too avoid having excess ice when freezing in a sorbet).
