Claude just became a craacked video game designer.
With the launch of Unreal Engine's MCP server last week, you can now build entire video games just by talking to Claude.
I spent the past few days building with it, and I'm telling you, this is going to forever change how video games get made and who gets to make them.
In this video I show you exactly how to set up the Unreal Engine MCP yourself and run through three demos: building a full playable city, cloning a real city from Google Earth, and creating custom buildings in Blender.
Here's the agent harness I mention too: https://t.co/mos9EwnZ2h
Intro
What I built in a few hours
Setting up the Unreal MCP server
Fixing the port 8000 connection issue
The agent harness that avoids the pitfalls
Demo 1: Building a city with City Sample
Demo 2: Cloning a real city from Google Earth with Cesium
Demo 3: Custom buildings with Blender headless
Outro
an OpenAI engineer just showed how he gets agents to do his whole job: code, debug and more, using loops
29 minutes from the engineer who coined "harness engineering"
he writes the rules, agents write the code, a reviewer agent loops until it's right
the winners won't have the smartest model, they'll have the best loop around it
watch it, then read the full guide on loops below
I genuinely don't understand why everyone isn't using this yet
Andrej Karpathy, a co-founder of OpenAI, posted a simple idea that hit 16 million views: stop using AI to write code, use it to build a second brain.
You point Claude Code at a folder, drop in any source, an article, a transcript, a PDF, and Claude reads it, links it, and files it into a living wiki of everything you know. It compounds like interest, the more you feed it, the smarter it gets.
Here's the whole thing:
> Install Obsidian, create a vault, open it in Claude Code
> Paste Karpathy's wiki idea file and tell Claude to build it
> Claude makes three folders: raw for sources, wiki for its pages, a CLAUDE.md that runs it
> Drop any source into raw and say "ingest this"
> Ask questions across everything, forever
Five minutes to set up, and you never start from a blank chat again.

No code. No files. Just pure AI vibes generating everything in real time.

autonomous robot driving through the field at night. no chemicals. no pesticides. just UV light killing pathogens and pests while everyone sleeps. this is @tricrobotics.
this is what chemical-free pest control looks like at scale.
