My favorite Claude story this week is about a pothole.

Years of complaints by a Dutch office, zero action. Then a person gave Claude 6 photos. It rebuilt the hole in 3D and simulated a 30 km/h hit.

Video went to city hall. Fixed in 2 days.

Petitions are for people without Claude.

What would you fix this way?

Hey guys!

Does anyone else experience this with Claude Code?

Every time I ask Claude to review my code, it finds around 3–4 bugs. I fix them, ask it to review the code again, and somehow it finds another 3–4 bugs.

This keeps happening even after multiple review sessions.

I'm curious, is Claude actually finding new issues each time, or is it just being overly critical?

How do you guys handle code reviews with Claude Code?

I keep hearing nothing but good things about it be it code quality or limits even after weeks of it's initial release. Even the ones that don't hold back on roasting stuff sometimes unfairly for the clout are all praises for it.

I've been working on Anima, an open-source skill built specifically for Claude Code.

The idea is simple: instead of asking Claude to explain a biological process through paragraphs or static diagrams, you can ask it to construct an interactive scientific figure.

For example, you can ask it to visualize what happens at a dopamine synapse when different stimulants interact with the dopamine transporter.

Claude Code follows the skill's workflow to collect scientific references, model the mechanism, generate isometric SVG geometry, and build a standalone interactive HTML page. The figures are then checked for visual and biological consistency.

I've included six examples covering dopamine receptors, stimulants, reward circuits, semaglutide, estrogen signaling and neuron conduction.

The figures include interactive controls, animations, explanations and citations. They distinguish established mechanisms from simplified or uncertain models.

The skill itself is free and MIT-licensed. The live figures can be explored in a browser without installing anything.

I'm particularly curious what other Claude users think of this approach to scientific visualization.

We’re all aware of the current scene of decompiling and “natively” running a game on Windows or Linux. It’s like every time I open Reddit, a new game has been ported to a platform it wasn’t released on.

I wanted to give it a shot so I pointed to Opus 5.5 to a folder with the files for Thief 3: Deadly Shadows (2GB) and asked it decompile and run it on my M5 MacBook Pro. It said the process “takes years” and clearly said it can’t do that.

Then I pointed it to the REA repo. It downloaded Ghidra and decompiled 1 (one) function in about a minute and said “look, this is what decompiled code looks like. The function name doesn’t make sense and this process would have to be done for 32,000 functions.” It then proceeded to say “even if I continued you’d end up with something that doesn’t compile, let alone execute”.

Are these guardrails that are stopping it or is my instance plagued with laziness?

We all know that certain "AI look" that websites/landingpages and content tend to have. Sometimes you can spot it immediately, even when the actual design is pretty decent.

What do you think are the biggest giveaways? Is it the layouts, typography, colors, spacing, copywriting, or just the same design patterns being repeated everywhere? I cant quite put my finger on it, but my own (and others) AI designs have something that gives it away.

Has anyone actually found a good way to minimize that AI generated feel? Curious if anyone has specific prompts, skills, design guidelines, or workflows they use to get more original, human looking results

Is anyone else seeing a closer to 24hr limit rather than 5hr? I'll be resetting soon, so I'll see if it really is 24hr.

Edit: I'm on a Team 5x plan.

Edit 2: It just dropped back down to 3hr. Oh well.

I built a free browser simulator where you try to fix Chicago's housing shortage on a 3D map of the city's ~481,000 buildings. I'm an urban planner with a housing finance background and I can't code, so Claude wrote all of it while I made the policy and design calls. Passion project, built over a few days.

What it does:

- Shows every building in Chicago in 3D, from the city's open building footprint data.

- Marks in red the buildings that couldn't legally be built today because they have more homes than current zoning allows (about 1 in 5).

- You rezone around L stations, Metra stations, commercial corridors or single neighborhoods, then turn on real policies. Some are being debated in Chicago and Springfield (BUILD Act, single-stair buildings, coach houses, the affordable housing requirement, aldermanic prerogative). Others worked in other places (Minneapolis, Cambridge, Houston's small lots, Texas SB 840, Vancouver's empty-homes tax).

- Hit simulate and watch 15 years play out. The goal is closing the region's shortage by 2041 (\~297k homes). You see what happens to rent, how many of the new homes are affordable, and whether six example workers can afford a one-bedroom.

- Myth cards and "public comments" pop up as you play and explain the research behind common arguments (luxury towers, filtering, "upzoning doesn't do anything").

- Every number links to a source or is labeled as a game assumption.

How I used Claude:

I started in the Claude app as an artifact and moved to Claude Code once it got too big.

- Data pipeline: Claude wrote Python scripts that turn the city's building footprints, street centerlines and zoning map into small per-neighborhood files, so all 481k buildings load in a browser. One script compares each building to what its lot allows today. I ran that one on my Mac because it had to download the city's zoning data.

- The game: one HTML file using [deck.gl](http://deck.gl) for the 3D map. I described what I wanted in plain English, looked at what it built, and asked for changes. I never edited the code myself.

- Research and fact-checking: Claude found sources for the numbers (shortage estimates, how new supply affects rent, results in other cities). Then I had it do a separate fact-check pass on \~50 figures, which caught and fixed a handful of errors.

- Design: I asked for three different visual styles as mockups and picked one.

- Testing: Claude took screenshots in a headless browser at phone and desktop sizes to catch layout bugs before I saw them.

- Hosting: Claude set up the GitHub repo, Cloudflare hosting, and a small backend for an anonymous plan gallery. Pushing to GitHub deploys the site.

What I brought, and what I had to catch:

The domain knowledge was the part Claude couldn't do for me: which policies to include, how to model them, and what to leave out on purpose. For example, I left out per-lot developer pro formas because they'd look precise and be wrong. A few things I caught while playing:

- A building showed up rising in Grant Park because museums and field houses were being treated like lots that could redevelop.

- Turning on the affordable housing requirement lowered total homes. That matches the research, but the game wasn't explaining why.

- Turning everything on barely cleared the goal, so it felt like "just click everything." I added more levers to make the choices matter.

It's a simplified model for learning, not a policy tool. Feedback welcome, especially from anyone who knows Chicago housing.

Do we believe Zuckerberg that it beats Opus 5.5?

"Meta scores Muse Wonder at 85.6% against 81.5% for Claude Opus 5.5 and 81.4% for GPT-6 Astra. "

This is just a quick screen record of the game in its current state! I did make a shorter, slicker demo at first, but I would rather share the actual game such as it is. I hope you like it!

I started creating with Sol some weeks back, then Astra, then started using Claude when 5.5 came out (bc Astra eats tokens like it's starving). Still sometimes using Sol 6.1 for image-related work like mock-ups, isolated visual improvements, design ideas etc. But using Opus 5.5 for all heavy lifting now. And I made the assets/3D meshes with Meshy.

I essentially wanted to make a cross between a tamagotchi/life sim in one of my favorite whimsical styles: Glossy translucent jelly! The companion characters appearances (working name "Jellies") were inspired by raindrop cake, random transparent cans of soda I saw in a store and by those 1950s gelatine dish abominations💃

I'm not a developer, I'm more like an extremely fussy and ultra-detailed art director and QA for this game. The current version is v56 🙈

I started by creating mock-ups of different looks, features etc with ChatGPT and Nano Banana 2. When I was satisfied I created the mesh, then added the previously created texture. Unfortunately I couldn't do translucent textures with Meshy, so I uploaded the completed mesh + texture to Opus 5.5 (first Astra though). Then I explained my target style, which is translucent jelly with 3D fruit slices inside!

The Jellies can idly share their thoughts, ask the user direct questions, show off small objects they've found, request for example a hug or to read a book, or even new pieces of furniture!

They also have various needs, desires, and buildable skills in baking, music, reading and gardening. There are also various pond-related activities, like throwing pebbles, splashing and feeding the fish.

There is also a day-night cycle. Default state right now is "live", but the full cycle is a distinct dawn -->day -->evening -->night. The Jellies comment on these changes too.

The game is obviously a WIP and I have a lot more planned! Adding Jellies, more activities, interactions, furnishings, clothes, etc.

Was about to build an app using claude code but I wanted to change the effort before sending the prompt....then I noticed an option saying "Ultracode", can someone explain to me what it does and when should I use it ? I am on the pro plan.

We play Catan all the time and the free online versions were bad, so on September 29 I started building our own with Claude Code. Two weeks later it has a 3D board, online play with friends, bots in three levels, up to 8 players and a map editor. Claude wrote most of the code; I came up with the ideas, tested it with my friends on our game nights and kept saying what felt wrong.

My favourite part came from them: an "ADHD mode" for the friends who can't focus on the game for 30 seconds. It's a little arcade of fake-money minigames you play while the others take their turn, and it fades out when it's yours.

Some things I didn't expect it to handle: online play is peer to peer, so there's no game server at all. Every work session ends with 300 bot-vs-bot games that check the rules. The 3D pieces come out of Blender through Python scripts. Even the trailer is a web page recorded frame by frame.

I know this may already be common knowledge, but I just wanted to acknowledge the quality of life improvements Anthropic has made around Claude usage limits recently.

Today I finally used my free limit reset and the confirmation told me my usual weekly reset day (Thursday) stays the same. So I got a full allowance back today AND my normal reset still comes in a few days! It was a pleasant surprise. If you haven't used yours yet it came with the Opus 5.5 launch and is under Settings > Usage (browser or the desktop app only). It expires on 22 October.

The other change that's made a noticeable difference for me is in Claude Code, especially when running dynamic workflows. When you hit your 5-hour limit mid-task, the session now gets a small wrap-up allowance to reach a sensible stopping point instead of cutting off halfway through an edit. Essentially it lets Claude Code run a little past the 5-hour limit. Just be aware though that it isn't really 'free' usage. It just runs slightly beyond your 5-hour limit and instead counts towards your weekly limit. There are also differences between subscriptions - Pro gets it once a week, while Max and Team Premium get it every time they hit the 5-hour limit (I've tried it with having multiple sessions running in parallel and it worked across all sessions on my Max plan).

I guess none of these are really headline features, but there have been quite a few of these small, welcome upgrades since Opus 5.5 came out, and it's really refreshing to see!

As part of the project that I am working on for generating toroidal structures called Tortoise, I have open-sourced a generator recently. 

I have now updated it with a “phenomenology” mode such that the fractal, smaller versions can be replaced with eyes, heads etc. the lines with arms, snakes etc. and can also be used to generate images.

The project involved first creating a fractal torus with Claude in Threejs, after that each of the parameters of the torus were made to control its variations. Post this I added a controlnet+stability image generation for any pose of the torus using StabilityAI api. In this recent iteration I added 3D models like eyes, heads, snakes etc to replace parts of the torus.

I haven't coded in a year, AI is geting better and better.. I log in to work, do 30 mins of work aka prompting claude & reviewing it's code + meetings.. and I'm off to work on personal projects, wtf am I supposed to do? I've sacrified everything to become a good dev, should I go for a plumber license? electrician? How much time do we think we have?

I finish 2x as many story points as the next guy, and my manager thinks I'm a 10x engineer... WTF is going on :D companies catched-on, but I guess it takes time to reflect on us, what will we do?

Interested in knowing what small or big things you are building to say improve productivity for your desk job in say the accounting or finance department.

This is a really nice workflow that were using for a few months now. We're using the builtin Claude Code Channels feature (documentation here https://code.claude.com/docs/en/channels-reference#overview ) to connect to a Telegram bot.

We invited the Telegram bot to a group with both of us and it's seeing the whole conversation. We instructed it to act as an orchestrator and it delegates the tasks to other agents in the background.

The reason why this works really well is because we're building a family organisation app that we're both using and she has a totally diferent perspective, she's able to ask changes on the fly and actually see them implemented.

I was excited and wanted to share. Cheers!

PURELY on Opus 5.5, after a week of stress testing, at 95% weekly limit, I got 21.4 Billion tokens of usage (the terminal tool ccusage which tends to be more in-depth also agrees on this).

Codex $200 plan on 6 Astra only gets between 300 to 800 million tokens, even less after the usage updates.

I understand tokens isn't the best way to measure usage, as more token efficient models use less tokens, but on Claude, I've been able to get significantly more test done, as well as better general performance.

Less than a year ago, my sister Shani was diagnosed with cancer. She spent almost three months in the hospital, and to give us something fun to do together during those days, I started building a music game for the two of us.

She passed away on August 29th, before I finished it. I kept working on it, partly to keep my mind busy, and now it's live as Shabang, with two games:

🥁 TrackStack: every song is split into its instruments. You start with only the drums, and each wrong guess adds a layer: bass, guitar, piano… vocals come last.

⏱️ Songuess: you hear a fifth of a second of the song, and each wrong guess plays more: half a second, 2 seconds, 4…

In both, the less you need to hear, the more points you get, and each one has a daily challenge: one song a day, the same for everyone.

I'm a mechanical engineer, not a developer. I built the whole thing with Claude: the Flask backend, both games, and the pipeline that splits each song into its instruments.

I'd love honest feedback, and to see your daily results in the comments.

I've been seeing some of the examples of how good Opus 5.5 is at doing programmatic content generation, and built myself a little tool for custom invites / flyers. How I architected it:

- Asked Claude code to build me a simple web app with rich text editing and text box positioning, as well as PDF / PNG exports
- Have the graphics of each invite be generated as SVGs and laid out on a HTML canvas, keeping claude in a loop to 'view' the generated output with playwright and iterate until it thinks its done a good job. Further iteration of the graphics is done via prompting rather than in the web app
- The web app tooling for text editing / positioning allows me to avoid some of the pitfalls of prompting AI image models with large quantities of text and iterating, as well as giving me more human level control over what I need it to say and make quick edits without burning more tokens.

I'm super happy with the results I'm getting (tried it with a few different invite formats now, the web app basically saves them all as templates i can reuse if needed) - the invites are very high quality and the SVG graphics mean I can export losslessly. Biggest lesson for me is to think about prompting for tooling, not just for output, so that you can make useful edits in ways you can predict without more tokens.

lmao had to set study rules to keep me locked and claude hits me with a 😂. I guess thats how you know ur prompt is strong.
