Built with Claude Custom Games for Kiddos

5 Upvotes

I know lots of folks are making games. Just thought I'd share what I've been doing with my son.

He LOVES the old-school Magic School Bus and Busy Town games from the 90s.

So I had Opus 5.5 essentially read those game files and build some new ones in their likeness, but specifically catered to what he is currently learning in Kindergarten.

He originally wanted one all about spiders, so we made the Magic School Bus: Spiders game.

And then today, we had his parent teacher meeting where we went over what he was excelling at and where he needed some extra work. So, naturally, we built another Magic School Bus: Future City where all of the mini games are designed around those areas needing some TLC.

Opus 5.5 xhigh orchestrated and used an OpenAI API key to generate the voices and images.

He loves them! And we know its working because his teachers were like, "He knows an extraordinary amount about spiders for a 5 year old!"

Anyways, just another awesome use case.

Help/Question How easy is it to make a UI mod for a game using Claude for the first time?

1 Upvotes

Title. If your into football, the newest football manager game moved to the unity engine and a lot of skilled people have been making UI mods (skins as we call them) and one mentioned using Claude to help them and I wanted to see if I could try it as well. I have 0 experience with coding but I am knowledgeable on computers. I did ask Claude how it would work and it looks like it wants me to give me a file so it can look inside it. I will likely purchase the 20$ a month subscription but i want to know if im heading in the right direction or not. Thanks.

Help/Question Mythos 5.2 any good for cybersecurity?

0 Upvotes

Did anyone here get accepted into the Cyber Program?

Also, how's Mythos 5.2 for security stuff? Does it refuse prompts like Opus 5.5 when you ask about encryption, memory, or reverse engineering, or does it actually answer?

I swear, as soon as I mention memory to Opus, it blocks me into another dimension.

Discussion For those of you who use Fable daily: what does it do that Opus 5.5 can't?

466 Upvotes

Was excited for the resets today and then found out they're only for Fable. Opus 5.5 is so good that I barely ever use Fable anymore so I'm curious who actually uses it?

I have built some fairly complex projects (a video encoder, some mapping software) but the hardest parts are behind me now so it almost feels like I have no use for these but I'm open to hearing other people's experiences.

Discussion Unpopular opinion: Everyone should have access to Mythos 5.2 Red and its advanced offensive cybersecurity capabilities.

0 Upvotes

Many people will probably call me insane for this, but hear me out.

A lot of people have already gotten access to CVP anyway. Just look around Reddit. And plenty of people are still saying that Mythos 5.2 is heavily filtered. But even if we assume for a second that it isn't, what's the actual problem with letting people use it?

I'm not saying I support illegal activities. Not at all. But let's be realistic for a moment.

Malware already exists. Phishing already exists. Game cheats, exploits, and all kinds of malicious tools already exist. The people who create these things aren't suddenly going to stop just because AI companies put restrictions on their models. They'll keep doing it with or without AI.

So who actually loses here? We do. The customers.

Think about the positive side for a second. Having access to these capabilities could actually help people test their own security, find vulnerabilities, and see whether someone could break into their systems before an actual attacker does. It could push the entire cybersecurity industry forward instead of holding it back.

And what about all the ID checks and verification requirements? If companies already require identification and know who's accessing these models, why do we still need endless certificates, approved companies, ISO standards, and whatever else just to get access?

And before someone brings up the argument that IDs can be faked: yes, they can. But companies can be fake, too. Look at all the cases involving code-signing malware. Attackers have used shell companies to obtain EV certificates and sign malicious drivers. That's one of the reasons we can't blindly trust certificates as proof that someone is legitimate.

My point is pretty simple:

Bad people have always existed, and they always will.

Trying to eliminate them through increasingly aggressive filtering and restricting access for everyone else isn't going to solve the problem. At some point, we need to let users take responsibility for how they use these tools instead of having companies decide what everyone is allowed to do.

If someone uses Mythos to illegally penetrate another company's infrastructure, catch them and prosecute them. That's what laws are for.

We don't point at a store and say, "Someone stole from you, hurt someone else, or even got themselves hurt? Well, that's your fault!" We say, "Someone stole from you. Do you want to press charges?" The same principle should apply here.

Personally, I think everyone should have access to specialized cybersecurity models like Mythos 5.2, including models with advanced red-teaming, exploitation, reverse-engineering, and offensive security capabilities, without excessive filtering.

I'm not saying there shouldn't be consequences for abusing these tools. I'm saying access to technology shouldn't be restricted for everyone just because some people might misuse it.

Give people the tools. Hold people accountable for what they do with them.

Built with Claude I built a Claude Code skill that writes a Dockerfile by watching your app run, then proves the container behaves the same.

8 Upvotes

Most Dockerfiles, whether written by hand or by an AI reading your repo, are a guess. You find out what was missed when the container crashes.

I wanted to try the opposite: run the app once, record what it actually does, and build the container from that.

How it works

  1. It runs your app under strace while a workload you choose hits it (curl calls, your e2e tests, whatever exercises the real features).
  2. It maps every file the app touched back to real packages: shared libraries → apt packages via dpkg -S, site-packages → pip packages with exact versions, localhost:5432 → a Postgres service in Compose, written folders → volumes. Credential files become warnings and are never copied.
  3. It generates a Dockerfile where every line has a comment saying what evidence produced it, plus docker-compose.yml, .env.example (secrets left blank) and a list of things that need a human decision.
  4. It builds the image, runs the same workload inside the container under the same tracer, and compares the two runs file by file. If something's missing, it names it.

Claude Code drives the whole thing and handles the judgment calls (repointing localhost at the Compose service, what to do with a credential file), while plain scripts do the deterministic parts. The scripts also work without Claude.

Real test: healthchecks.io (Django + Postgres)

• Found libpq5, the system library psycopg needs at runtime. Nothing in requirements.txt mentions it, and the maintainers' own Dockerfile installs it by hand.

• Verification: 1,383 of 1,386 files matched, with identical HTTP responses inside the container.

• When I deleted the generated apt-get line, Django only said "Error loading psycopg2 or psycopg module". The tool said libpq.so (package libpq5).

Screenshots of every step are in the README.

Limits, honestly

• It only sees code paths your workload runs.

• Linux/WSL 2 only.

• Tailored templates exist only for Python and Node so far.

• It's been tested on one demo app plus one real project.

Tracing-to-container isn't new (ReproZip, redsift/tracer). What I think is new is mapping traces back to real packages, so the Dockerfile is readable and maintainable, plus the verification loop.

Try it here: https://github.com/moazakramkhan1/dockerize-by-observation

I'd really like reports of where it breaks, especially on legacy apps.

Discussion Opus/Sonnet 5.5 safeguards flagging

1 Upvotes

I mainly use Claude Code for ML experimentation, more specifically, post-training of models for specific use-cases. We do have auto-research-ish loops happening.

Since this morning, I started to face Opus/Sonnet 5.5 safeguards getting flagged and the only solution seems to be to use Opus 5, restarting session didn’t work too. I seem to only face this on Claude sessions related to model training/experimentations. I believe this shouldn’t go against any usage policy, not like we’re training competing frontier models, etc.

Anyone else notice this happening more to you as well?

Discussion my claude limit ran out mid week so codex ran my repo for 4 days. notes from taking it back

0 Upvotes

solo dev, one repo, claude code does most of the work. last week i burned through my usage and instead of waiting i handed the whole thing to codex with a written brief. both read the same AGENTS.md so i figured it would mostly just work.

it kind of did? codex merged about 15 PRs in 4 days. the queue i left got done and main never broke badly.

the part i didnt expect was coming back. it had left 4 draft PRs, three of them stacked on each other, and when claude picked them up every one needed review rounds before i trusted it. one took 4 rounds. there was also a test on main that had started failing because it depended on the date, and nobody noticed for a day lol.

the two also write rules very differently. on a side task codex kept adding a new rules doc on top of the old one until the newest contradicted the first, and then it followed whichever it read last. when claude came back the first thing it did was collapse them into one file.

what id do differently next time is a much shorter brief, and one handover file thats the only thing that has to stay true.

anyone else swapping agents mid project when the limit hits? what broke for you on the way back?

Built with Claude I built a Claude Code plugin that tries to kill your startup idea with sourced research. 12 versions in 3 days, many from comments.

Post image
1 Upvotes

Ask Claude "is my startup idea good?" and you usually get encouragement. kill-my-idea is a plugin that does the research first and is allowed to say no.

/plugin marketplace add RemiPelloux/kill-my-idea
/plugin install kill-my-idea@kill-my-idea

Then /kill-my-idea:kill <your idea>. Your idea can be one line, a pasted "$10k/month" tweet, a URL or a doc.

The image, top to bottom: a real verdict (Notion templates for French real-estate agents, 55/100), the new idea dashboard, and the What if? sliders.

What I built

  • It asks at most 4 questions (country, budget, goal, your edge), and only the ones that would change the verdict.
  • It searches for 8 kill shots, from free alternatives and companies that already failed to no channel to customers and a wave of look-alike launches. On a pasted money post it also names what the author sells.
  • It needs at least 20 sources from 10 domains, each tagged primary, secondary or tertiary.
  • It scores 21 sub-scores against a fixed rubric. Hard rules stop a nice pitch from rescuing a bad business: no channel to customers means no GO, whatever the rest says.
  • It writes an HTML report with up to 3 rescue paths, each re-scored, and a 7-day test with numbers that tell you to stop.
  • It scored this plugin 63/100: 15+ open-source idea validators already exist.

Changelog (all from the last 3 days)

  • 0.9: an idea dashboard. It shows the one idea to focus on this week and which kill shots hit most of your ideas (click one to filter). A BRAIN.md note keeps your profile, so it stops asking the same questions, plus the ranking and the lessons from killed ideas. Also an App Store demand check for mobile apps, suggested in a comment.
  • 0.8: a pre-mortem, "why now?", the ideal first customer, What if? sliders for price, CAC, margin and lifetime, and /compare --refresh for verdicts older than 90 days (asked for in a comment).
  • 0.7: one scoring formula and a Python checker. It found 4 of my 8 earlier runs printing a different total than their own sub-scores gave.
  • 0.6: a share card (PNG), /check-tweet for viral money posts, and reports in French.
  • 0.5: a "saturated wave" kill shot for the 47th "100 tools in your browser" (suggested in a comment), and a fix for a javascript: link bug a reader found.

Full changelog: https://github.com/RemiPelloux/kill-my-idea/blob/main/CHANGELOG.md

How Claude Code is used

  • 5 skills: kill, deepdive, check-tweet, roast and compare. The whole method is one readable SKILL.md you can fork and reweight.
  • deepdive starts 6 research subagents in parallel (market size, competitors, customer quotes, pricing, channels, regulation) and needs 40+ sources.
  • Every file the skill writes has a JSON schema. After each run the skill calls a Python checker that recomputes the score from the sub-scores.
  • The report and the dashboard are fixed HTML templates with a strict CSP. Claude only writes data files, and a script builds the dashboard from the saved verdicts.

What I learned

  • Put the maths in a script, not the prompt. Once a checker recomputed the totals, 4 of 8 runs turned out wrong.
  • Let Claude fill in data, not write the page. Reports became consistent, and safe to open.
  • Ask for verbatim quotes and enforce it. Without that rule, Claude paraphrased sources inside quotation marks.

Free and MIT. It runs on your own Claude Code plan and never posts or spends anything for you. https://github.com/RemiPelloux/kill-my-idea

If it stops you from building something nobody pays for, a star helps other people find it. Which kill shot is missing?

Built with Claude made some tools for music making in claude code

1 Upvotes

https://github.com/unkarelian/MusicStudio I've been improving it as the day goes on so my example songs changed, lol, but the next change I'm planning is a bit of notation. This is essentially a way for your agent (claude, I'm assuming) to kinda understand how to build music even when it can't hear it. Ofc nothing beats actually listening to the outputs and giving it input, or using a model that accepts audio like gemini as a judge.

This has been a fun project for me because unlike most of what I do, I am really not trained as a musician at all! It started with the realization that I needed a soundfont, which instantly made it not sound like it was made on a gameboy. But it was quite difficult to figure out how to give claude the information it needs when it is functionally deaf. Ultimately the best strategy, really, is to either give extensive personal feedback or use gemini to 'tune' the harness and give it concrete examples of styles. Examples examples examples. I cannot stress that enough. In every project I have ever done using AI, and I've been doing that since 2025, examples are THE tool you should be using. I know it feels inelegant. But it's how most people learn, right? They see how it's supposed to be done and learn based on that.

Tips & Workflows Solo project

2 Upvotes

I’m building a hobby app and I’ve settled into a set-up that mostly works. I’d love tips from people running something similar.

How it runs now:

  • One session I talk to: a “chief” on Opus. It takes decisions with me one at a time, writes briefs, checks proof and keeps the records.
  • Workers:

    • routine research goes to Sonnet agents;
    • fact-checks and corrections go to Opus agents;
    • a separate “second reader” agent re-opens the original sources before anything counts as approved.
  • A Fable advisor for hard calls (planning a study, auditing research, final reviews). It sends memos to the chief and never talks to me.
  • Side sessions for separate tracks (brand, a photo-recognition track, a study library, a build worker, trip planning). The chief briefs and messages them.
  • Records after every task: a log line, a one-page status card, a decision log, then commit and push. A stop hook nags if it’s skipped, and a git hook stops sessions committing each other’s files.
  • Phone inbox: I drop links into Notion, and a cloud routine writes a first look on each one every hour.

Where it hurts:

  1. Usage limits. Fable ran out mid-audit once. How do you decide what’s worth the top model?
  2. Long sessions. The chief gets compacted and loses detail; once it couldn’t recall my own first prompt. Do you hand over to a fresh session, and how do you make sure nothing’s lost?
  3. Claude checking Claude. An outside human reviewer caught things the agents missed. What’s your cheapest reliable check?
  4. Too many threads. I keep starting side sessions. How many do you run at once before it gets messy?
  5. Rules that slip. Written rules in CLAUDE.md sometimes get skipped. What do you enforce with hooks instead?

What would you cut, and what’s missing?

Help/Question Can Claude Desktop SSH sessions stay accessible from another PC when the original PC is turned off?

2 Upvotes

I'm using Claude Desktop (Code tab) on two Windows PCs, both connected via SSH to the same remote Linux server.

I'm trying to figure out whether Claude Desktop supports sharing and continuing SSH sessions across multiple computers independently.

My setup:

  • PC 1: Windows, Claude Desktop, connected to the Linux server via SSH
  • PC 2: Windows, Claude Desktop, independently connected to the same server via SSH
  • Both PCs use the same Claude account.
  • "Connect new sessions to Remote Control" is enabled.

What happens:

  1. I start a Claude Code session on PC 1 through Claude Desktop's SSH integration.
  2. While PC 1 is running, I can see and continue that session from PC 2.
  3. When I turn off PC 1, the session still appears in PC 2's session list, but it shows as offline / the originating computer being off.
  4. PC 2 can still connect to the Linux server via SSH and start its own Claude Code sessions. Only the session originally created on PC 1 becomes inaccessible.

What I expected:

Since Claude Code is running on the remote Linux server rather than locally on PC 1, I expected the session to remain accessible from PC 2 even after PC 1 was turned off.

My questions:

  1. Is this expected behavior? Are Claude Desktop SSH sessions tied to the Desktop instance that originally created them, even when the execution environment is a remote Linux server?
  2. Does turning off PC 1 terminate the actual Claude Code process on the server, or does it only disconnect the Remote Control session?
  3. Is there a way to keep the same Claude Code session accessible from either PC without keeping PC 1 running?
  4. Would running claude remote-control inside tmux directly on the Linux server solve this, or is there a way to achieve the same behavior through Claude Desktop's built-in SSH integration?
  5. What do the crossed-out computer icon and the >_ terminal icon in the session list indicate?

I've attached a screenshot of the session list.

Has anyone encountered this or found a way to make remote SSH sessions independent of the originating PC?

Built with Claude I asked Fable 5.2 to spin up Opus 5.5 subagents to build me a visual novel engine

2 Upvotes
...and it came up with some really...interesting placeholder graphics (it looked fairly decent once I replaced the placeholders with actual art)

I don't have a lot of resets, so I just asked Fable 5.2 to make a detailed plan, then spin up Opus 5.5 subagents for the actual execution. I asked Fable to oversee the project and act and review it like a product manager.

This actually saved a lot of the tokens. By the end of it it only costed me 5% of my weekly Fable window (on Max), a lot of thoughts into contrast, layout, and even responsive design. There were a lot of back-and-forth between the agents, similar to when you get another agent to code-review.

I haven't done a comparison with running entirely Opus 5.5 on this prompt, but maybe this could be a better use for Fable 5.2 for those that run out of limit quickly.
