In case you missed it on X and Reddit last week, there’s a story about a SaaS built entirely with AI assistance—zero hand-written code. Here's the story:
Short version:
Long version:
Just a reminder that you can screw the whole thing if you have no idea what you're doing 
The story has become a cautionary tale about the "invisible complexity gap"— the difference between software that works on the surface and software that's secure and robust in production. It’s a reminder that while AI tools can be incredibly powerful, understanding the underlying technology is still crucial.
Prime (and guests) are doing a 7 day live 'Vibe Coding a Game' stream using Cursor...
Very entertaining!
What am I watching!? 
I think they drank one too many red bulls. Kinda reminds me of Mythic Quest.
I started playing with Cursor this week on a project using Claude agent. I really like how it can modify the files and allows me to accept/reject and even run commands on remote machines (compose down/up, view files), but I feel like their implementation of Claude is somehow constrained.
At a certain point in large projects, it makes mistakes and doesn't fully understand an issue and tries to fix it with "patches" that start to Frankenstein the project. If I open Claude Desktop, and give it the same files from github, it does a much better job at resolving the issue I was trying to solve in Cursor. It doesn't make sense why Claude Desktop performs better than Cursor when supposedly they're using the same model.
Blame the coffee!
Although not everyone's cup of tea (the personalities are a bit strong) they do know their subject very well. Took me a while to actually enjoy Primes streams as a little over the top energy wise. But then my wife said I'm the same! Not sure if it is a compliment or a flaw, a bug or a feature?
We have totally abandoned Claude in absolute favor of Deepseek, Qwen, and Grok. Tried Cursor when it first came about but soon went back to VSC with Cline and then Roo (although still in favor of Cline). Trying to learn a bit more about Cursor by watching the stream. But then am really happy with Cline and VSC (with Open Router) so don't see me changing path any time soon.
Does Cline show the files it's editing with changes added/removed that you can accept/reject?
Yes absolutely Keith. You can also define your own instructions to insure this is even more persistent if you wish. ie instruct that 'only by typing accept in to the response will the change be made to the file'. We also, as a precaution, have an instruction to create a backup of the file we have made changes to and add a date stamp to it, and place it in to a directory named backups. You could even further and ask it to then create a .json file with all the backup files which contains their location, date, and description of the accepted change. Take this file to then create a page that tracks these changes. Thus you'll have a full history of all accepted changes... Have I gone too off on one or does this help? Just like Prime I'm on to my third pot of coffee already hahaha...
The above is also a nod to Teodors original post. Never let AI do all the things. Always track and understand them or be the guy who didn't and we'll read about it on X or Reddit in a month or two!
Just give it a security MCP.
MCP is one thing Anthropic deserve real praise for!
Have you tried Windsurf? I have a feeling they might deal with large codebases slightly better than Cursor
Edit: Just tried on a big project, probably not good enough
“A fool with a tool is still a fool.”
After four month of Cursor usage...
ello worl
and using Claude...
