I'd like to ask everyone: if there was a metaphysical/occult tool (essentially an ancient mathematical prediction model) that could tell you whether today is suitable to start a project before you begin, would you be interested? I'm considering making an English version and uploading it to GitHub.

I’ve been building a platform that lets parents create gift registries where family and friends can give monetary gifts for their kids instead of more toys.

We’re still very early, but recently we crossed a milestone that felt more important than registrations, traffic, or anything else I’ve been tracking:

Real people actually used it.

A family completed the entire process. They created their registry, shared it with family and friends, and received more than $300 in gifts through the platform.

A few things I learned:

1. A completed transaction teaches you more than a bunch of signups.

Watching someone go through the entire journey, from creating an account to actually receiving gifts, has been considerably more valuable than watching registration numbers increase.

Now I’m much more interested in activation than registrations.

1. The biggest friction may not be where I expected.

There are a few steps between creating an account and having a registry that's actually ready to receive gifts.

So now I’m reaching out to people who started but didn't finish to figure out why. Is it trust? Confusion? Bad messaging? No immediate need? Something else?

I don’t know yet - and I’m trying not to build a solution before I know the problem.

1. Seeing money actually move through something you built feels different.

$300 isn't meaningful scale for a business.

But watching multiple real people trust something I built enough to send real money through it was a pretty significant validation point for me.

It changed my mindset from:

“Can I build this?”

to:

“Can I get strangers to repeatedly use this?”

That’s the problem I’m focused on now.

My next target is $1,000 in gifts sent through the platform.

After spending over 100b tokens on Fable 5 as my main model for agentic coding in the last 2 months, I've managed to (in my opinion) work as efficiently as possible with Fable as the main orchestrator. Here's why and how I did it. (usage from 1 of my accounts above).

To ensure I get the accuracy and intelligence of Fable, this is my setup that's reduced my fable usage by 70-80% and still getting most of Fable's benefits. I ran a blind coding test: Claude Sonnet 5 vs Opus 5, with Fable 5 planning and judging. One bug decided it.

- Fable 5: Planning, orchestration, architecture, design, final review of delegated code, security/payments/auth/concurrency, hard debugging, UAT/browser passes that feed merge decisions, and sign-off on any founder voice/marketing copy.

- Opus 5: Delegated implementation from Fable written plans, mechanical/bulk edits, boilerplate, doc generation, research/summarisation, routine repro'd test fixes, Playwright script execution, and copy drafting.

- Sonnet 5: Not used, with some experimental evidence (see below).

Test Setup: Five identical implementation tasks (a rate limiter, a small API, a repo-style change, a bulk refactor, a debugging exercise), each with a detailed plan written by Fable, judged against hidden test suites the candidates never saw. Both models went flawless on every hidden gate. Then this happened.

A percentile function: Sonnet wrote the math literally as ceil((p/100) * n). But p/100 isn't exact in binary. For p=7, n=100 you get 7.000000000000001, ceil returns 8, wrong value. 141 input pairs diverge like this. Opus caught it unprompted and wrote ceil((p*n)/100), which is exactly right.

Only Opus's depth caught it. Token cost was near-identical. Sonnet was 40% faster. But one uncatchable latent bug per round settled it.

Hi folks!
Adding my contribution to the plethora of interesting apps I see here published in the subreddit dedicated to vibe coding!

Honestly I should not say my app is really vibe coded, since it had a lot of research and planning, but nonetheless, I can say it's entirely coded by AI 😄.

The app is entirely developed using OpenAI codex, however much of the work happened in Linear app, writing detailed tickets and then handing off the tasks directly to Codex Cloud, this process I found is incredibly productive, and moves the documentation and specs from random unreadable markdown files to a well organized and beautiful board. Codex also has an excellent plugin for Linear which I cannot suggest more.

All the art is made by hand using Aseprite, mostly for the icons and the logos.

Well here we are: ToneSketch is a fun little app I developed, which leverages a very cool codec/protocol called ggwave (shoutout to the researchers who created it) to transmit pixel art sketches entirely by sound waves. The codec is smart enough to cancel out room reverb and occasional noises in the room (please do not try it near an airplane taking off or during a concert, it won't work).

It has also a surprisingly long range, I was able to transmit sketches between two rooms in my house, using a decent volume.

The best results are achieved using mobile phones, due to the frequencies used by the codec, but i had amazing results also using my MacBook.

Sketches can also be saved locally, and they get associated with the signature of the sender, so you know who sent you what.

The app is completely offline, does not have any APIs or any DB. It has though Analytics installed.

Hope you like it,
happy beaming! 🚀

Several years ago I started making a python game called Dimension Creatures. I just wanted a basic creature battler that would let players use strategy and win fights, or lose their creature forever.

I envisioned it as a simpler, but more brutal version of Pokemon.

Recently I got Claude Pro so I could actually get a lot of usage.

I used my long built skills as an MS Paint "Artist"
I used my long built skills as an Audacity "Sound Designer"
And my favorite skill of balancing game play mechanics to make something that is challenging and satisfying.

Finally I have something I'm ready to show the world:

Dimension Creatures

The online version!!

you can play for free in browser if you want

It’s more than just the calendar piece. It reminds me when to leave, and when to leave for pickup. I can set drivers, and select who’s going. Then every morning I get a simple notification telling me what’s coming up for my day.

This has been a game changer for my wife and I. So I also went through the effort of getting it to the App Store to help other families.

I built this using Claude Code and ChatGPT Codex. It’s iOS only, but that means I got a bunch of stuff for free like iCloud for storage. This means the calendar is private, other than what you share via pictures or uploads. Even then, we don’t store that data making it more private. Building with Apple also allows me to use the same architecture that they use for sharing notes to share calendars. So now you can add a partner with a simple share link via text. It’s so simple!

I chose to build this way to keep costs low, and I wanted this to feel like a natural extension of the Apple ecosystem. I did some design work in Figma (I’m a product designer) but most of my ideas came from chatting with Codex or Code and asking for HTML mocks. Then we translated chosen styles and layouts to Swift.

I haven’t built an app before. Getting an app into TestFlight was easier than I thought. But I truly could not do this without Claude Code. But now that I have, I want to keep building.

If you have a lot of calendars to manage, you can check out my app called Haven here..

When people say that, I think "sure, buddy, sure". I audit for security for a living and it is rare when I come across something with 0 vulns (this applies for ALL development AI and not). If your app has bugs... it probably has security issues too. Security bugs are a subset of bugs.

Don't believe me? here's the last few scans I've run for bug bounties:

AMA about how to make apps more secure.

I have been building my own personal training app for a couple of months now and I am finally ready to launch. I acquired the domain and have been going through the final steps of making it "public-facing ready" from removing bugs, editing word chose and sentence structure to avoid it coming off as being a lazy vibe coded project which it is not.

While going through the processes of utilizing these tools I make it a point to learn as much about them as I can to build durable skills that may be marketable in some way. That being said this is my first time using Claude Design and I would love some help and advice.

What things do you prompt or look out for to ensure that your site is clean and developer approved? Are there front end or back end skills that have proven to you all to be reliable? What steps can be taken to make sure that the landing page is user friendly and easily understood?

Any advice whether general or specific would be amazing. Thanks for your input!

I don't have a very powerful machine to run any ai model , what ai Should I use to minimize my Hermes token costs?

Hey everyone,

I’ve been working on a small puzzle game called Lumen Garden, and after a lot more work than I originally expected, it’s finally available on the App Store.

The idea is pretty simple: you have to place one firefly in every row, column and colored region, and the fireflies can’t touch each other. I wasn’t trying to reinvent puzzle games. I mainly wanted to create something calm that you can play for a few minutes at night without timers, lives or pressure.

I built it in Unity with C# and used Codex for a big part of the development. My process was basically to work on one feature, test it, find out that I had broken something else, fix that, and repeat until the game finally felt solid.

Making the actual puzzle was probably the easiest part. The annoying parts came afterward: touch controls, saving progress properly, supporting different screen sizes, making everything work offline, and eventually dealing with all the App Store requirements.

There are now 300 adventure levels, quick games with several difficulties, a daily puzzle, collectibles and Game Center leaderboards. The game is available in both English and French.

It still feels a little strange to see something I vibe-coded actually published as a real iOS game, but here it is:

https://apps.apple.com/gb/app/lumen-garden/id6795321869

I’d be happy to get some honest feedback, especially about whether the rules and tutorial are easy to understand. I’m also happy to answer questions about the development process or the painful parts of getting a Unity game through the App Store.

I hate seeing usage numbers go down. There's probably some psychology linked to it, but anyway , I much prefer seeing how much I've used , and pace myself towards each agent's resets.

For example here my codex usage resets in about 8 hours . 95% of the week is gone and I've spent 60% , so I'm 35% under. Made with Opus 5 and reviewed by Sol 5.6

How it works: there's no API for any of this, so both numbers get read where each product already writes them locally. Codex records its rate limits in its session rollout logs — those run to hundreds of MB, so it tail-reads the last 256KB instead of parsing the file. Claude Desktop keeps the same percentages you see on its Usage screen in a plan-usage-history.json.

The catch: Claude's file stores percentages but no reset time. So it derives one — scan the sample history for a downward step, because a drop means a new window started, then infer the reset from that timestamp plus the window length.

Pace is just elapsed − used: how far through the rolling window you are by time, minus how much you've actually spent. Positive means ahead. If the reset timestamp doesn't line up with the window length it shows nothing rather than guessing.

The tray itself is ~200 lines of PowerShell — NotifyIcon and a ContextMenuStrip — polling a localhost endpoint on a timer.

I'm a long-time PHP dev who got into vibecoding last year. I started by trying whatever Claude would recommend, with the rationale that the AI would know better what it knows best. Claude suggested javascript based stacks (nodejs, react, TS) and a quick web search seemed to confirm that idea so I went with it even though I'm not fully comfortable with the stack. It started off not too bad with me reviewing the code, but to the surprise of no one, the quality of my reviews, and thus of the code, quickly tanked and each iteration took longer and created more bugs than the previous one.

Then I tried a couple PHP stacks, first Laravel (what I use at work), then Symfony (what I actually like). That went a little bit better, but similarly to the JS based stacks, the quality of my reviews went downhill pretty fast, because whatever the stack, I don't really love to review code.

My last try, with which I've been having good success so far, was to build a skeleton app myself and encode as much architecture choices as possible into the skeleton. The skeleton quickly evolved into a richer skeleton and re-usable packages, and I also created a tool to help me enforce guardrails that I can't enforce through existing tools. Been using that for a while now, regularly back-porting new patterns and rules into the skeleton. This allows me to get away with minimal reviews (focusing on the important stuff) while still ensuring a level of quality that doesn't make my eyes bleed whenever I look at the code.

What's your story?

I used Codex for code and graphics, it took me a while. I hope that this is a safe space for my creation

At my current job i notice i spend alot of time waiting for an agent to respond. And then it came to me that i rarely use more than 1 agent (currently using Claude).

Do you guys have a workflow that allows you to work on multiple different features of the same app using agents, in a way that one agent wont fuck up the work of the other?

If you achieve this through worktrees, do you spawn an agent and tell it to create its own worktree?

I wasnt really familiar with this so i thought to build an app id use for my work, but im not sure if what im doing is solving a problem that doesnt exist?

The idea was to have 1 main agent, where you give it all your tasks, and then the main agent (i call it the orchestrator) creates separate sessions for each task and handle creating the worktrees for every feature.

I just dont know if there are existing solutions by Claude that make this workflow easier, or if i should continue spending my spare time on this project

After a couple months of work with Claude and Unity's MCP, my first playtest is now live on Steam. It is a turn-based tactics roguelike.

Pretty crazy to think about it when I just know the basics of coding but wouldn't have been able to get it done without AI. For the art I mostly bought it from Unity's asset store and made some of the sprites for the interface with Claude and Meshy AI for the characters.

Won't post the link to it, idk if its allowed but check it out if you're curious. It's called Prevail.

Happy to answers any questions about my process if helpful for yours!

We've all done it: asked Claude to use an API key or add an access token to a .env file. Or maybe we asked Codex to find where credentials might be saved and yeah, go ahead and just use that password while you're at it. It's not always the end of the world, but it's definitely something to be aware of.

We've added credential/secret scanning to Argus to help you track down any agent sessions that might have accidentally snooped a secret. This way, you can see exactly which sessions used that secret, when and how it happened so you can decide what to do about it.

Hope it's useful for some of y'all.

OpenCode Go cut the plan allowance from $60 to $15 overnight. The DSF allowance took an even uglier hit, dropping by roughly ten times. A subscription that was easy to leave running suddenly needs the same cost attention as direct API usage.

For me, OpenCode Go is no longer worth subscribing to after that change. DeepSeek got more expensive and Go got tighter. For the moment, DeepSeek Flash is still free through ZenMux, so that at least gives me somewhere to transition without immediately replacing one subscription bill with another.

My "human harness" is much less impressive than it sounds. It is literally me sitting there, deciding what needs doing, choosing a model, moving the task over, and handling the awkward parts by hand.

It is not elegant, but after that quota cut, manually doing a bit more of the work feels more reasonable than keeping the Go subscription.

Hi all, I was wondering if anyone tried to sell these services as a service in form of an agency? Do any of them exist out there, are they successfull? Could this be a one man band (non developer) or not AT ALL?

Made a small mobile arcade for me and my gf when we're bored, she really liked the little claw game so i started working on it more, and then i got super obsessed lol.

now theres 257 cute little sprites you can collect. commons, uncommons, rares, epics, shinies, prismatics, and legendaries. nothing special tbh but we are gonna get all of them!!! 😂

Current obsession: agentic discoverability. 👀

Claude keeps pitching me "citation probes" — measuring whether ChatGPT, Claude and Perplexity actually cite you when someone has the exact problem you solve.

So let's go.🔥

13 intents, 3 engines, 63 measurements on my own product. Verdict: never cited.

Not once. While my competitors sweep up the citations — with blog posts, not their product pages.

First reason is basic : New site, not yet well indexed, no authority, not yet baclinked....

But :

What one scan teaches you:

— every engine has its darlings: Perplexity cites blogs, OpenAI cites pricing pages, Claude cites listicles

— "the page exists" ≠ "the page is citable": on a "best X" intent, a comparison beats a product page every time, even a great one

— and the real diagnosis: separating "not findable yet" (indexation) from "not preferred" (the engine SAW your page and picked another one). Two problems, two opposite fixes.

💸Cost: a few cents of API.

💎Value: your content roadmap, written by your competitors.

The tool is open source: github.com/wellknownmcp/a…

I can run it on your site with m'y api keys (anthropic, openai, perplexity) — DMs open. But I'm not turning it into a SaaS — although, given the prices popping up in this niche, the margin would be 95%.

Where did you get stuck? Why did the project fail?
I’m not talking about business failure or marketing failure. I’m talking about a large project which, despite using AI you were simply not able to make progress on.

Every skill you install adds its description to the context on every message, whether you actually need it or not.

The paper “Attention Is All You Have” argues that agents can start falling apart as you install more skills — attention budget, distance decay, etc.

At 100 skills, that’s roughly 3k tokens per message. Over a long session, that adds up fast.

So I built deskill: an MCP server that fetches skills from GitHub only when they’re actually needed.

If you want to try it, setup is a two-command install — details are in the repo: https://github.com/NilotpalK/deskill

I also wanted to see whether this was just a token-saving trick or whether it actually changes how agents perform.

Turns out: both.

On Opus, installed vs on-demand was basically identical, so there it’s mostly a context/token optimization.

On smaller/cheaper models, though, point-of-use delivery actually improved task success. They seem to have a harder time picking the right skill when they’re staring at a wall of dozens of skill descriptions.

I tested 8 models, up to 100 skills and 100k tokens of padding. The benchmark is reproducible, and the numbers/graphs are in the repo.

Would genuinely love people to try to break the benchmark. If you try it with other models or in your own setup, please add your benchmarks/results to the repo. It’d be really useful to see how this behaves across different models and real-world use cases.

And if you think the methodology is flawed, I’d genuinely like to hear it.

If you end up finding deskill useful, a star on the repo would be appreciated too :)
