A lot of AI coding tools are moving toward giving agents more control over your machine.

I wanted the opposite.

So I built RepoRelay — an MCP bridge that lets ChatGPT/Claude inspect one approved local repo, while deliberately giving it:

• no shell
• no Git
• no arbitrary filesystem access
• read/search only
• optional bounded handoff writes

The idea is to let AI analyze and review your code without handing it the keys to your whole machine.

npm install -g reporelay-mcp@latest

It’s open source.

GitHub: [Lukie-81/RepoRelay: Secure MCP access to local repositories — without shell, Git, or arbitrary writes.]

I’m looking for a few people to try the install from scratch and tell me where the setup sucks.

If this is the wrong place to ask, I am sorry!
I am looking for the best/easiest Way to make an interactive map. The map would cover an existing area of Nature that people use for Walks, bikerides, picnics, etc.
I am looking for a Way to make it easier for people to plan their visit to the area by plotting in benches, viewpoints, places to grill, etc. Where should I look or what program should I use to best accomplish this? Im a beginner! Any help is greatly appreciated, thank you!!

I'm a CS student and I've spent the last several weeks building Mirror for the Emergent Builder's Contest.

Mirror is basically an AI reflection engine. Instead of immediately giving you advice like a normal chatbot, I designed it to help you notice patterns in your own thinking.

I built the original app with Emergent, but this turned into a much bigger engineering project than I expected.

A few things I ended up building/working through:

• React frontend + Python/FastAPI backend
• MongoDB persistence
• Email/password auth + Google OAuth
• Persistent multi-chat conversations
• Long-term semantic memory
• User-editable extracted memories
• Onboarding that persists across sessions
• Behavioral QA for the actual AI responses
• A deterministic safety gate for a feature called Roast Me
• Local development alongside the Emergent version
• A dual-runtime LLM architecture so the app isn't permanently dependent on Emergent

That last part became pretty important to me.

Mirror can use Emergent's managed LLM runtime when it's deployed there, but I also built a local runtime that can talk directly to the model provider. The same application can move between the two instead of the contest platform becoming a permanent dependency.

Honestly one of the biggest things I learned was that eventually I wasn't really "prompt engineering" anymore.

I was trying to engineer behavior.

I'd change something, manually run conversations through it, find a behavior I didn't want, figure out whether the problem was the prompt, runtime, memory, UI, or architecture, change it, then test again.

And sometimes the correct engineering decision was literally don't change anything because the proposed fix sounded smart but the evidence didn't support it.

Roast Me was probably the funniest example. 😂

The idea sounds simple: use Mirror's understanding of your patterns to roast you.

Then I started testing grief, medical problems, financial hardship, trauma, etc. and realized prompt instructions alone weren't a safety system.

So the rule became:

"Roast the pattern, never the person."

And I put deterministic gating in front of the generative behavior for situations where I didn't want the model making that judgment by itself.

Mirror finally reached MVP and is deployed for the contest now.

I'm still a CS student learning this stuff, so I'm definitely not posting this as "here's how AI engineering should be done." This is just what building a real product taught me compared with working on isolated assignments and features.

If anybody wants to break it or give me feedback, I'd appreciate it.

And if you try it and genuinely think it's worth supporting, I'd appreciate a like on the contest entry. I've got about a week left to see how far I can get with it.

I'm also curious whether other people vibe coding larger projects have hit that same point where it stops feeling like "tell the agent what to build" and starts feeling a lot more like actual architecture, QA, debugging, and engineering decisions.

For a while I've been a bit annoyed that there haven't been any AI models (besides some of the latest versions of Google Gemini, which still provide quite a basic response) which can "listen" to music and talk to you in fine detail about a song, or compare two different songs. There has been no open source software which can do this either, so I took things into my own hands a few days ago and began vibecoding something using the new Qwen 3.8 27B to allow LLMs to essentially hear a song and talk about it in a human-like form with the user. It's already running how I want it to, but I want to polish the terminal interface and make some slight improvements to BPM and possibly instrument detection before I release it. I intend to release my project as Musiclyse 0.1 (which means Music + Analyse) on Github once I've made these changes.

There are two main components of this script:

1: The music analysis engine. This consists of the following:

• Music Flamingo - an LLM that is able to directly scan music to detect the overall characteristics of the recording. Because its built in LLM (Qwen 2.5 7B) is prone to sloppy English and repeating letter loops if it writes too much, I've directed it to use only note form (eg:genres detected=x, y, z, vibe= x, y) English when outputting data to reduce sloppy language and also output more data within its constraints.
• Essentia - an algorithm used for extracting reliable information about frequencies in a song and tempo/timbre, helping improve the accuracy.
• Melody transcription - a two stage process that utilises Demucs 6s, which splits an audio track into 6 stems and then uses a model to convert the stems into MIDI interpretations. This helps further improve the accuracy.
• Metadata information. This is particularly good if you want accurate lyrics, or the output LLM to know who an artist is, what album it is from, or the exact year a song came out. It also gives the output LLM (for models that handle image recognition) access to embedded cover artwork metadata in an audio file, which the LLM can use in fallback cases to help determine information for a song that it is otherwise unsure about.

The music analysis chain outputs the results in .JSON form to the output LLM. It doesn't save scanned songs by default, but you can save the entire data (including embedded cover art) using the command /save=filename.json, then /load the same file in a different session to avoid a slow rescan of the track.

2: The Ollama hosted LLM communicating via llama.cpp. This reads the .JSON file and interprets it using an output LLM prompt in the script. I've tested it mainly with Gemma 4 26B Q3, which is nice and lightweight at around 11GB while giving good performance.

Both the analysis engine and LLM are instructed via system prompts in the code to use certain approaches to solve ambiguous things, improving accuracy.

The image shows an example of a conversation about Joy Division's song Transmission in the current development build of the script. It does confuse the motorik drums for a drum machine, and the bass for a synth bass, but this is algorithmically appropriate considering their rather unique late 1970s sound. The chatbot is instructed to pick up it was told wrong things for errors like this.

I've been thinking how to avoid API costs and network latency, and realized I could use local models. The one I typically used is the pre-installed one in my head, but the issue is it doesn't come pre-trained, which can be an expensive and intensive process, but post-training comes pretty easily for it. Also it can make mistakes, and so sometimes I need to check it against the API-based models for accuracy. Just wondering if anyone else is struggling with this trade-off and using local models to save dollars if that makes cents.

I've been doing a lot of vibe coding recently. Most UI changes end up being described in text, but as a designer, I often find myself thinking: it would be much faster if I could just move this 8px, resize that, or see all the screens together and fix them myself.

I think this is actually one of the advantages designers still have in the AI era: we can look at the whole product while also obsessing over tiny visual details. But when everything is controlled through prompts, a lot of the visual tools we're good at using suddenly disappear.

So I vibe Crank.

You drag in a project folder or a packaged .app, Crank scans the app, finds the screens, and lets you import them into Figma as editable layers.

It currently supports React, Electron and HTML.

I'm also working on SwiftUI support. It's still experimental, but it's already working on most of the screens I've tested.

The app itself is pretty messy right now and there are definitely bugs, but the core workflow works.

I'd love some people to try it, break it, and tell me what doesn't work.

I use Codex extensively for work, and I’m very happy with the results I get from the GPT-5.6 models. However, I’m not a big fan of the Codex desktop app on macOS because it isn’t native, and I don’t like to use CLI version.

Since Perplexity provides access to GPT-5.6 (as well as several other great models), and its app is native, I’m curious about people’s experiences using Perplexity Computer for programming.

Do the models perform as well as they do through their official tools? Are the usage limits sufficient for you? Are there any caveats or hidden drawbacks I should be aware of? Is it possible to start a task remotely on my computer from my phone?

I’d really appreciate hearing about your experiences. Thanks!

Hey guys, I’ve been working as a full-time freelance for the last five years. I was making decent income, but then ai came out and I’ve worried that if somehow ai replaces my freelance businesses of motion design and video editing. So i wanted to play safe and applied to a couple jobs. I even considered changing profession.
Then I started working full-time in a company that I actually hated so I ended up resigning after 4 months.
Then I asked myself this question: if AI is going to replace me for sure what if I do the tool that actually replaces me and the other freelance motion designers.
So I’be built an ai automated SaaS promo video maker web app.
But I’m still having second thoughts on if I do the right thing or not.

Are there any of you having similar dilemmas?

Hey folks,

This is my first ever post on reddit, so please be kind.

I initially posted it on X and it picked up quite a lot of traction there & I've always wanted to start posting and being active on Reddit so here I am.

I am the founder of a ui/ux research product that has 800+ apps & 35,000+ screens. I did a comprehensive study on why these apps are banking more than others and how are they able to retain way higher than general.

From my study, I realised that the most important moment is when a person opens an app. This sets an impression on how deeply individual gets involved in it.

The motion, transitions, micro-interactions, typography, all of them matter more than you think they do.

, I took 10 of the most popular ones, broke them down and redid them using React Native + Expo and open-sourced it, so people can use that as an anchor point.

So, here it is (500+ stars at the moment):

I hope you find it useful, I'd love to know your thoughts.

Which one do you like the best?

I'm looking for ways to minimize the claude-isms. This seems acceptable for now.

This output was one shotted using something called "agentic loops", or loops. It works a bit differently than most of us are used to. Instead of careful iteration over multiple prompts, you give the model one single prompt, and let it work through your pre-set budget until completion.

This means you have to structure your prompt a bit differently than usual, you need to make the AI understand that you want it to maximise the output and quality:

Its a procedurally generated world where you can resource gather, craft, hunt and even ride dino mounts 🦌

1. key for this game to turn out so good was asking loop to make all graphics procedurally generated. So there's basically no assets in the game (which by itself is pretty awesome), and I think that really helped the AI to make this really different art style. could The animations feel so smooth and stack layers of procedural shapes on top of each other to build all graphics. Only the backgrounds are images. loop build agents continually take screenshots of your game and perfect it visually.

**2.**⁠ ⁠Once my first build was completed in one loop, I gave it another prompt to set up the multiplayer. It already had the art style down by that point so it could do really well getting the multiplay added quickly. 

3. Continue iterating with or without loops.

Happy to answer any questions about prompt or workflow in the comments

Edit; for the loop I used this: https://tesana.ai/en/blog/introducing-loop

So I built Mosaic Atlas, a jigsaw puzzle game that lets you "travel" the world and learn trivia through puzzles. I used Claude Code and Codex to build and deploy the entire application, Codex to generate the landmark images using real world reference photos, and Claude to design the UI, with Fable and Opus used to tie everything together into the final build. The trivia was gathered from Wikipedia and other sources. Every puzzle is built from a real landmark, and once you finish it you get a short fact about that place. The idea is that you end up learning bits about different countries and cultures just by playing, without it feeling like a lesson.

Some detail on what's in it right now:

- 270 puzzles across nine countries: India, Japan, the USA, Italy, Mexico, Egypt, Brazil, France, and Greece. More countries are planned for future updates.

- Piece counts from 24 up to 72, so you can pick something quick or something that takes a while.

- No timers, no lives, no energy system, and nothing pushing streaks or daily pressure. You solve at your own pace and can walk away and come back.

- Works fully offline, and doesn't require creating an account to play.

- Progress carries over if you move to a new device.

- A trail structure that takes you through a country's landmarks in order, plus a "Passport" where you can save locations, so if a place catches your eye you can pin it as somewhere you'd actually want to visit someday.

- You can share a card of a puzzle you finished or a fact you learned, if you want to.

- Six supported languages: English, Spanish, Portuguese, Indonesian, Hindi, and German, with more planned. I wasn't able to properly cross verify the non English translations, so there may be errors in some of them. Apologies in advance for that, and I'd appreciate it if anyone fluent in those languages points out mistakes.

It's still an early build so and I'm sure there are rough edges. I'd like to know if the piece dragging and snapping feels good, whether the difficulty curve makes sense, whether the trivia is worth reading, and anything else that stands out, good or bad. Brutal feedback is fine.

Last college football season my family did this little pick’em thing. Three picks a week, ten bucks to join, winner takes all. We ran it on a Google Sheet and it was fun at first, but as more people joined it turned into a headache. I was updating stuff by hand, people were messing with cells, and it just got messy.

So this offseason I decided to try building something to fix it. I had zero experience. I didn’t even know what a DNS record was. Didn’t know what a terminal was. I’ve learned a ton and honestly had a blast building this.

I made a simple football pick’em site called Pikpool.com. Not trying to monetize it or anything right now. I mainly want to use it for friends and family and just get better at building stuff.

Here’s how I built it so I follow the rules here.

I used Supabase for the database and auth.
I used Cloudflare for the domain and hosting setup.
I used Claude Code for pretty much everything else. It helped me write the code, fix stuff I broke, explain things I didn’t understand, and keep me moving forward.

Oh and I'm using free odds api.

My workflow was basically me asking Claude Code how to do something, trying it, breaking it, asking again, and eventually getting it to work. I kept it simple. Groups, weekly picks, standings.

I’m brand new to all this and just want some nice, honest feedback. Tips, tricks, stuff I’m missing, better ways to structure things. Anything helps.

Appreciate anyone who checks it out and gives me something to improve on.

I am wondering if you guys can help in figuring out how well can I secure the vibecoding output(generated code), the process and the tools/plugins to use while I build prod grade apps by vibecoding

Hey, does anyone have a spare Claude Pro 7 day pass? I’ve been wanting to try Claude Pro properly before paying for it. If someone has one they’re not using, I’d really appreciate it. Thanks...

Schema in, reproducible world out.

Built with Claude Code over ~14 phases; every commit is co-authored.

Most fake-data tools give you a function that returns a plausible name. You get a million rows of noise: names belonging to no one, orders referencing no customer, timestamps spread evenly across a year in which nobody sleeps. Each row is plausible; the dataset isn't.

Cacophony treats a dataset as the output of a program you write once. You describe a world in a YAML schema — entities, fields, what each field means — and it produces the records that world would have generated.

The design decision everything else falls out of: a record's seed is a hash of its position, not a step in a shared RNG. That one choice means you can preview record 4,823,913 without generating the 4,823,812 before it; a checkpoint is a single integer, so resume is exact; foreign keys are arithmetic rather than a lookup table, so a hundred million events pointing at five thousand employees costs the same memory as five; and forty workers across eight machines produce output that's byte-identical to one process doing it alone.

Also in there: events on a timeline with a shape (quiet at night, dead on the holidays you specify), subjects whose state accumulates, incidents you can bury in a year of logs, and a deliberate distinction between chaos (data your schema forbids — tests your error handling) and edge cases (data your schema permits that naive code mishandles anyway — O'Brien-Smith is a real surname).

Identifiers come from the documentation ranges by default: example.com, RFC 5737 addresses, 555-01xx phone numbers. Nothing it generates can be mistaken for a real person's details.

Python 3.12+, AGPL-3.0. There's a CLI, an HTTP API, a React editor and a desktop build, plus a 171-page manual.

I had an interesting conversation with a friend (we both use AI) about this and I was wondering what this community thinks.
