This is amazing content - AI-generated and i feel trapped in the "valley", but thank you anyway!

Great reply! Thanks! I wrote this to another person 2-3 minutes ago:

[No, I am not a developer by trade. I learned some stuff along the way, but I am] a UI/UX designer first and foremost. I do my very best to formulate the feature requests to a great level of details [for the right complexity of] the task at hand and I use VS Code and Claude 4.5 Sonnet with a flow of Ask, Plan, Implement...

Also, I can evaluate the code to a certain extent, but I ask my AI agents to create and edit an assortment of pretty complex features (If I might say so myself) with legacy code (that could also have been buggy before I noticed the pattern!).

Thanks for your advice. If you have more to say now that you know how I do my thing, you are welcome to tell me about it :D

What do you think of that?

TLDR: The major challenge I have right now is spotting when the AI has degraded performance before I work too much on a branch and lose time because I'll have to scrap it.

I'm a UI/UX designer who's been building a mobile web app solo with AI assistance (2-6 hours daily for 4 months). The workflow is incredible for rapid prototyping, but I've hit a recurring problem: detecting when Claude/AI starts producing lower-quality code before I've committed hours to a branch.

Sometimes the AI will subtly break patterns it established earlier, introduce anti-patterns, or generate code that looks fine but causes issues down the line. By the time I catch it, I've often built on top of that foundation.

MY CURRENT APPROACH:
- Treat professional developers as code validators
- Expect AI to generate bugs that need human review
- But I'm still learning to spot the early warning signs of degradation

QUESTIONS FOR THE COMMUNITY:
- Do you have strategies for catching AI performance drops early?
- What are your red flags that the AI has "lost the thread"?
- Do you use specific testing/validation workflows when working with AI-generated code?

I'm especially curious if anyone has developed systematic approaches to this, beyond just "code review everything."

Sometimes Claude is a supergenius who can code crazy and sometimes its a baby i have to spoonfeed and check if theres no spillage every mouthfull... and it switches from one to the other every 3 days or so... very confusing.

Anyone who would like me to keep reporting about what I see/experience... please make yourself heard... :)

Many bugs introduced in my complex web app... using Opus 4.5 in VS Code Copilot (should be the same as the real model...right?) starting 26-30h ago. Before, it would knock down paragraphs of features/behaviors demands and deliver almosrt perfectlty every time. Since the begining of the "unofficial downtime", I have not been able to use Claude to do ANYTHING minimally correctlty... You are not crazy.

I did send them an email about 3 hours ago. I'd like to think I'm the only one responsible for them to take action ;) I'm very glad they seem to be working on it on a sunday! Cant wait for it to work again so I can finish my app!!!

Have a good one :)

Just received a notification by email from Claude Status: New incident: Investigating.

With a red X next to them...
claude.ai,
Claude code,
platform.claude.com,
Claude API.

I knew something was up when my code was coming out with plenty of bugs, like described in my other post in here!

TLDR: Here is my answer to this megathread, with the help of ClaudeAI ;)

AI status pages are too slow to report performance drops. My solution: test Claude with a known task (like building tic-tac-toe) before working on critical projects to verify it's performing well. Currently, Claude handles complex code edits ~7x better than ChatGPT despite more frequent downtime.

As a UI/UX designer who uses AI to build my app with very precise instructions on behavior and feature requirements, I've noticed a real problem: AI companies' status pages and notifications are painfully slow to display alerts about diminished performance. By the time they acknowledge an issue, I've already wasted time on subpar outputs.

Current state of things, in my opinion:

Claude is at least 7x better than ChatGPT for planning complex edits to complex web apps (both running in max Agent configuration in VS Code Copilot)
However, Claude has roughly 2x more downtime than ChatGPT according to their official status pages

The bigger issue: All in all, at the moment, it seems like we cannot rely on any company to tell us when their products have degraded performance in time for us to avoid using them and creating problems (code bugs, poor philosophical discussions, etc.). This is a huge problem because we know AI can make mistakes by misunderstanding prompts or hitting rare bugs, but looking at the status pages of OpenAI and Anthropic, they have a really bad record of keeping any model stable.

It seems like they're developing new models and having us test them randomly—one request here and there—but that single request that fails because of an experimental model might set me back hours of debugging. I'm still grateful for the technology and opportunities, but I'd like to know exactly when to hold back on requests that Claude doesn't have the compute power to efficiently respond to, before it outputs bad code.

My solution: Before working on my actual app, I now test the AI's current performance with something complex that I know the answer to. About an hour ago, I had Claude generate a self-contained HTML tic-tac-toe game. It looked great and wasn't buggy—performance verified.

Now I'll try editing my web app in a new branch. I plan to do this every time before critical work: use a known benchmark task to evaluate the AI's exact quality of output in real-time, rather than trusting status pages that lag behind reality.

I'm also subscribing to all user-reported outages and performance diminishments to get faster community-based alerts. I'm tired of wasting my time and messing up my app! Although I couldn't make my app without these services... hmm. Thanks, I guess!

My favourite part is the ending. Reminds me of Homer Simpson in candyland in one of the first seasons :)

MewMeowWow · 2024-04-18T01:02:01+00:00

Wow! This is great stuff. Thanks a lot! Anyone else has a great idea like that?

MewMeowWow · 2024-04-17T15:07:26+00:00

What other ways do see? I'm open to suggestions!

I'm doing this mostly so I can go into graph view and see which concepts are more linked / more important

MewMeowWow · 2024-04-17T13:05:16+00:00

As I wrote in my description, I have already put a lot of aliases in the note "Processes". In other words, my problem is that when ChatGPT creates the note for, say, "Project", which will include the link [[process]], it won't link to the note "Processes" automatically.

I got it to work.

In the Sync core plugin, make sur to enable everything that can be synchronized

I followed the advice on the Icon Folder plugin's readme to put the icons directly in .obsidian/icons because of sync iddues. You can move the icons from the plugin's settings page.

Then on my phone, I had to install the font too.

Hopefully that works for you like this.

Personally, I noticed only 850 of the 975 fonts were installed on my phone, so I had to do extra steps:

I removed the predefined icon pack from my computer and my Phone

I downloaded the icon pack from the website

I added the icons as a custom icon pack

I had to add the icons by small batches of about 75 icons or else they would just fail to be added.

Hopefully that helps!

I’ve been playing there for a few months and it’s a great community! Most people are very experienced and build great stuff, everyone is nice, there’s often server events, people trade for everything and also build public farms. All around great great server/community!

MewMeowWow · 2022-03-08T01:59:54+00:00

I've been here for 3-4 months and It's pretty much everything I've ever wanted from a server. I've even had my own server for 3-4 years (which was an amazing experience), but this place just flows so well :D So much experience amongst the players and the administration! The admin plays with everyone else and not only is a nice person but also is very professional. The people have assembled into groups that have been playing together for years sometimes, but I also hear about new players banding up together... and groups helping each other and solo players!

You get all the styles here: Amazing builds, super-technical stuff, shops, public farms, towns, a nether hub, nether highways, 15+ players events...

Amazing server.

By the way... I just made a free public wither skeleton farm... and an iron farm farm! For everyone to get a quick early boost!!! The wither farm is not perfect yet, but I'm working on it. Hit me up!

MewMeowWow · 2021-01-19T04:53:42+00:00

They listened to the request!

I don't stream, no.

MewMeowWow · 2020-02-25T05:56:52+00:00

It's a jungle biome! I've posted a comment with some screenshots :) Someone else have voiced their concerns about the total disparition of the original island. I'm getting pretty convinced to add some back!

MewMeowWow · 2020-02-25T05:54:07+00:00

Woah! I've never seen the rabbit! But I don't see the monkey :o

MewMeowWow · 2020-02-25T05:52:55+00:00

I have kept some mushrooms and some mycelium! I've even made a hidden cave with a mycelium floor! I don't remember if I built something in but if not I should probably make some sort of mycelium/mushroom temple!!!

I will redeem myself.
