Ask HN: Is anyone experimenting with different ways of using LLMs for coding?

26•yehiaabdelm•1h ago
I'm a bit annoyed by the feeling that we're kind of stuck when it comes to using LLMs for programming.

I use Claude Code and Codex, but I haven't been able to enter flow state like I can when I hand write code.

This is kind of ironic to me since AI should be a bicycle for the mind, but right now it feels like a bicycle that just brakes abruptly every couple minutes. I stop, wait, review, prompt again.

Is there anyone exploring something fundamentally different than the prompt response loop we have today?

I actually think the idea of a tab model is directionally better than prompt response.

Would love to hear about any startups, personal experiments, etc.

I think the value right now is to focus less on external orchestration if at all. trust the (current best) model to do it better than anything you bolt on to the harness. focus your energy on providing clearer specs. I think the optimal spec is a disambiguated (through liberal use of the AskUserQuestion tool) 1 intent, 2, input/output contracts 3 constraints and 4 preconditions. focus on that and get out of the models way. I think of it like this, imagine a person who was not as smart as you was trying to tell you how to do a task. would you want more verbosity and step by step instructions or would you want them to just cut to the chase (ie, what are you trying to do, what are the obstacles, I'll let you know if I have questions).

also let the model verify itself. don't give it an objective that is vague, give it clear exit criterias for goals and let it loop until it gets there so much of the orchestration scaffolding seems like massive technical debt

oddly, I do the opposite of a lot of conventional advice when it comes to models. I use no memory, I think there is something similar to context rot when everything is stored. I like creating markdown files as memory that the model can grep if needed. I also havent found a real use for hooks yet, I have tried but they always seem to get in the way. skills on the other hand are very undervalued. they are so much more powerful than many realize. I used to think agents were where the power was. I think its actually skills. agents are really for context preservation. skills are what increase capabilities

I'm not even talking about quantity of items in memory, I mean dilution of intent. I really love a model with a clean slate and only the items it needs. I fear the memory guides the model in areas that might not be what I want with the current prompt

progressive disclosure is a big one. you can make context available but it is only loaded when needed. like lazy loading for prompt engineering. skills are to be used to instruct the model how to do something specific that is not in its training data. like how to access my proprietary system, how to interface with a custom program. you can embed templates in skills, you can embed code that executes in skills and only the output is loaded into context. skills expand capabilities, agents constrain context

(constraining context is a very good thing btw, don't mean to infer that agents are somehow inferior to skills)

It feels like everyone and their grandma is building an agent orchestrator at the moment, but I'm not hearing a lot of success stories. The fact that Anthropic and OpenAI haven't laid off all their software engineers already is probably a sign that orchestration breaks down somewhere. I suspect it's just a more elaborate way of burning tokens. I'm still interested in experimenting though.

I’m writing a JSX templating language — to manage context, branching, etc automatically. You hand it a spec/existing work and it automatically applies a recipe.

So far that’s been much nicer for anything large or complex, because I was spending all my time on context piping.

I keep a TODO file where I just write my ideas in free text, and every once in a while I tell claude "I updated the TODO file".

This is basically like queueing up prompt.

I wish Claude Code had a thing like that builtin. Like a "user ideas scratchpad".

I'm currently rolling out Matt Pocock's Sandcastle project so that I can have those brakes removed. What will be left is just the grilling(/wayfinding).

My current flow heavily relies on Matt Pocock's Skills and Sandcastle project. I find them highly valuable in practice: grilling(/wayfind) into a spec and extract issues. Those live in Linear projects. I'm pointing my Sandcastle set-up at such Linear projects (or loose issues), which results in an MR.

Currently at the point of self-improving the prompts and Sandcastle set-up with a retrospective pass of the logs.

Ive built a couple things in the past few months that have leaned heavily on LLM as my programmer. Mainly Claude code, but occasionally codex also. Its a different way to produce. I spend more time doing something like plain text feature mapping. simple .md files, good flow and creativity. Then once i'm happy with it, i pass it off to the dev team- claude to code up and integrate. I feel like im flowing in the part of the process I always was. But the buzz of getting something working is gone. More like slow satisfaction of getting something useful at the end.
kybernetikos•51m ago
One of the things I've been talking about with my senior developers is how the bottleneck has shifted even more dramatically to human code understanding vs code generation. AI is still not suitable for generating production grade code without a human checking it (yet), but it can produce a huge amount of code for humans to check. We've been experimenting with ai finding better ways of communicating what is in a change at different abstraction levels etc by always generating diagrams showing what it did etc, with the concept being that anything that can speed up human understanding of changes addresses the core bottleneck of the whole process.

I have a custom harness that runs in a macOS VM. It has e-mail and its own accounts. I assign it tasks in Linear, it does them and spins up PRs for me to review. This works pretty well, generally. I have to spend time writing stories and doing code review, but I don’t have to follow its (their — I have 3 of them) every move.

Not being able to enter flow state is a very interesting observation. I've felt it too to the extent that I went down a whole new rabbit hole of what it means to be in flow state. Let me know if anybody here wants to know more, happy to post some links.

To answer your question - I discuss the approach with Claude Code (e.g., should I implement my own ACT model in JAX or PyTorch, Python or Rust or Julia, etc.). Then write the initial part of the code myself. Opening up a blank vscode is a simple joy of life I refuse to give up :-) I'll ask Claude for advice if I get stuck, it will helpfully offer to write that code for me, I obstinately decline. Eventually, I'll get bored of some minutiae or other, at which point I'll ask Claude to complete just that part of it.

thinkingemote•37m ago
I'd be interested in the rabbit hole of flow state. Also with regards to the dopamine rewards of solving a bug as motivation.

Sometimes using a LLM can assist these and sometimes it can feel like cheating myself out of a good thing and I'm not entirely sure where the borders are. It could also be related to a sense of ownership or pride in ones work and seeing the value in doing quality work.

Ok here are the flow related links. This was about 1.5 years ago when I was trying to figure out burnout and it turned out flow (or lack thereof) was closely related.

If you like videos, I saw an interesting video yesterday about systems thinking, software as ecosystem particularly with AI. More of an overview but gives an insight into seeing where we might be able to experiment with different ways Its more focused on teams and companies than individual developers but I think it could be applied to the single dev.

chilmers•44m ago
I don't think you would expect to get into a flow state if you were intermittently directing another (human) programmer to do work, and you shouldn't expect to with LLM-driven coding either. Perhaps you are best finding out ways to extend the length of time where the LLM can work without prompting, then use that downtime to focus on other tasks that will help you to guide it better the next time you need to prompt it.
sixothree•16m ago
I feel the opposite. Creating a DTO or wiring up a CQRS command takes me out of the flow. And while I enjoy a good refactoring, it would be nice if I could just have it refactor code in the background while I'm still working in the same file.
fabioz•43m ago
I'm in the same boat and I'm not a fan on the current way of working of agents, but I think tooling is what needs to catch up.

So, I actually decided to try to tackle it myself and worked some months (full time) on it.

https://beolis.com is the result of that, it's a local cli in a kanban board style with a remote server to keep the team on track (I've been using it myself for some time and actually started to ask some friends to use it just yesterday -- feedback very welcome, I still wanted to do some additional things before asking more people to use it, but oh well, I'm a fan of building in public anyways and it's probably better to have feedback sooner rather than later).

The main point there is that you work mostly in the ticket description (your own spec) and the plan (the spec as the agent sees it, generated with a custom workflow) and then having another custom workflow to implement it (you can choose how you want it -- https://beolis.com/blog/post/custom-coding-workflows has some info on what I'm using myself).

As a result, at least for me, I do spend more time immersed in a flow state (although I'm in that state writing the specs and reviewing code -- although in some cases it's more work to write the spec in a way the agent can work when things get more complicated vs just diving into the code, so, going into "code" mode is something I still have to do, agents are definitely not perfect).

I guess I'm lacking in docs on how to effectively use it. I have plans to create a video next week and post it in the blog, so, if you're interested, keep track of it ;)

I am currently in the process of launching my AI teams platform that I've been working on since at least January. It's https://PersonaStack.ai. I'm doing it without VC money and all by myself. I've used over 110B tokens so far building it.

You get some amazing results with teams of AIs if you do it right. The key is to control behavior with what integrations and responsibilities each agent has. That way they naturally adapt, delegate, fact check each other, and generally act more autonomously.

This is already running the automated news site ainews.personastack.ai complete with social media posts 100% automated.

It also runs the issue triage, coding, reviews, and releases for the Kuberhealthy open source CNCF project, which is another thing of mine.

I don't think the next step is really smarter models. It's how we make the models more effective, and teams, when done right, net the best results I've seen.

Hoping to get noticed here soon, but it's extremely hard to do solo I'm finding.

dnikolovv•37m ago
Doesn't this go directly against what the author is asking about? You're much less likely to enter flow state if you have a team of AI agents which are supposed to be autonomous.
sigmoid10•34m ago
Maybe project managers will finally get to experience flow states?
fraXis•34m ago
Very impressive, especially since you did it solo. The website looks great and explains everything in detail.

Can you elaborate more about its development? How much do 110B tokens equate to in $$$? What LLM did you prefer most during development? Any suggestions for other solo developers trying to launch their LLM-built product?

Fixing that for you.

I haven't been able to enter flow state like I can when I write code.

You are the bottleneck.

Why should AI be limited to human time. Is a mountain? A galaxy?

philbo•31m ago
YES!

It's still very wip, I spent a couple of weekends on it so far, but I'm working on a harness that eschews autonomy and instead aims to work as a pair programming partner. Key to that are distinct "driver" and "navigator" modes, with the capacity to flip between them rapidly.

(not really usable yet, but after tomorrow's session I expect to be developing opair in opair, which is mildly exciting)

bob1029•31m ago
I've been working on inverting the control theory for the agent loop. Instead of the user initiating everything, the agent runs automatically in the background and calls the user for feedback as part of tool use. The end game for me is to get rid of the chat interface altogether and move back toward async email and other messaging channels. The chatbot UI as a means of driving the business always felt like a temporary stepping stone / clever demo.

I think there are 10-100x productivity gains lurking in here. It is very expensive for a human to reserialize their mental state into a prompt each time a task needs working on. An agent can do this ~instantly and with high frequency 24/7. The higher the rate of evaluation the less change has to be dealt with between any two iterations. So, the likelihood that a given iteration needs human help goes down as you increase the rate of evaluation per unit of wall clock time. Tighter and faster control loops tend to require less severe corrective measures than slow and sloppy ones.

This is the most plausible reason for so many tokens in the future. I can actually see a million tokens per second making sense. I have a pretty good idea how I'd approach this if I actually had access to this kind of infrastructure. 1Mtok/s is baby tier in terms of raw information theory. The politics of employing a system like this are far more terrifying to me than any technological aspects. Humans really like having control over things, even when that control is pure downside for the business.

I created a small PI extension that always watches relevant directories and answers me in place, without switching context, or using a chat interface. Still experimenting but I like it.

I'm building "workboxes" to work on my startup. It helps me develop features insanely fast. A workbox is a simple worktree-in-a-sandbox per feature. I have a simple front end where I can launch new workboxes: I input a prompt (a documented grilling session) and it creates a branch, a PR, and starts an opencode coding session on an e2b sandbox based on a custom template with the app's monorepo. Each workbox has a public https endpoint so I can manually test the web app after the coding session is complete. At any point I can either approve the PR, send a follow-up prompt, or connect to the opencode session for more control.

I think my next step is to perform the grilling session inside the front end, currently I perform it in my terminal and then paste in the front end.

magicmadrid00•27m ago
Well, it always depends on your environment. In my case, nothing forces me to heavily use AI, so my workflow is kind of the old way, but with less hassle.

- Do your thinking alone. (AI part: search, understanding)

- Specing. (AI part: search, understanding, completing some text)

- Coding like the old days. (AI part: search, understanding, code examples)

- Okay, now I have a good idea of how my feature is going to work

- Look for fluff code and delegate it to AI to write/review it.

- Focus on the part of the code I want to have fun doing.

- Review.

- Repeat.

It’s slower than the approach of doing specs and letting AI do the rest, while focusing your role only on code review. However, I’m more in control of what I build, I can explain what I built better than everyone else, and I build up my knowledge. (also I have less problems, because less code haha)

Will I go for the full Agentic way ? Maybe but I will find a way to slow it down so I can be in control

danpalmer•27m ago
Something I'm thinking about and doing a bit of experimentation with is using LLMs to write specialist higher level code.

Rather than ask them to write web-apps in webby languages with open source frameworks etc, providing a very fixed, on-rails development process where everything is abstracted away. Accept that it'll be less powerful, but take the trade-off that it'll hopefully be faster and produce much more controllable software.

Concrete example, why do we let the LLM choose a database, schema, migration procedure, library, etc. We could decide to only support one database, enforce schema design (such as every table containing access control), enforce a migration process, enforce a library, even do schema design in a fixed config file rather than arbitrary DDL. Same for auth, deployments, even UI.

villaaston1•4m ago
This sounds a bit like Ruby on Rails including Hotwire? Even has the “on-rails development” in the name, schema design in a config, migrations, etc.

Though some frontend decisions are a bit more open

yehiaabdelm•24m ago
Just want to add:

I'm trying to do the same amount of work faster, not do work in parallel or agent orchestration. I'm not against letting the model go off and do things on it's own, that has its time and place.

But if I can do something in 15 minutes instead of 1 hour without the annoying prompt response loop, without the feeling that there could be blind spots, and while keeping all of the context (or at least most) in my head. That's a bigger win than spinning up 5 agents to do different things.

neepoPhantom•17m ago
The fundamental problem i keep seeing across all harnesses is the use of the exact same UX afforded by a git based backend. If we want to stay in flow, the LLMs edit backend would have to be based off something like crdts to handle simultaneous edits.
Incipient•13m ago
My current approach which I've been testing on two MVPs with what I would call 'moderate success' (but hey, actual success!)

3 tier, philosophy-spec-design. Increasing detail. Design files include db model explanations and pseudocode/function headers - that level of detail.

For each thing I need to change, I have a, prompt ready to go to ask the agent to follow about 5 steps and it outputs a 'reviewfile' with details of what it things about the thing I posited. I review its output. I have another prompt ready to then get an agent to generate a taskfile + update the design documentation. The taskfile explains in great detail what has changed and what needs to be implemented. I review the taskfile and got diffs of the design doc changes. Finally an agent implements the taskfile. I review all changed code and commit.

It gets there, but still definitely misses some stuff. It's very adequate for a MVP I'm finding.

Edit: this seems to only work with Opus. Sonnet can't do it (maybe I'm just lucky and Opus is seriously compensating for an awful approach and I'm just lucky?)

pjbeam•8m ago
I'm in the middle of it so don't have any conclusions for you, but I started mucking with building my own cli coding app and there are _tons_ of levers available that aren't apparent from claude code or codex.

Including altering the turn concept. I think it is still ultimately call and response but instead of everything is a quarter note you can get a little closer to a beat you like.

doganarif•4m ago
using tools like claude code and codex constantly boosts our dopamine, making hyperflow impossible. these days, most engineers work on multiple projects simultaneously to satisfy their dopamine receptors.
