Anthropic hired this engineer at $250K-$750K a year because he knows how to build harnesses for multi-agent systems
In a 15-minute workshop, he shows exactly how to build one from scratch
AI → Agents → Harness → Loops → Graphs
step 1 → start with the Claude Agent SDK - the harness handles loops, context, and sandboxing
step 2 → separate the brain from the hands - reasoning in one place, tools in a sandbox, 60% faster to first token
step 3 → run it server-side and log every step - close your laptop and it keeps running, crashes resume from the log
step 4 → make failure cheap - retry dead sandboxes and replay lost context instead of starting over
step 5 → turn yesterday's logs into new memory and skills - the harness wakes up smarter
Anthropic calls this "dreaming"
Most people spend weeks building this by hand

Just realized they are all chilling without a phone in their hands, actually talking to eachother, gossiping, laughing. Just to watch this is kinda relaxing
INSTEAD OF WATCHING NETFLIX TONIGHT. Spend 2 hour with this. Claude AI FULL COURSE that teaches you how to BUILD and AUTOMATE anything. The people who watch this tonight will wake up tomorrow with a new skill. Watch it and bookmark it now.
A man spends 50 years teaching at MIT.
He knows his time is running out.
So he records one last lecture — everything he knows, distilled into a single hour.
He died 5 months later.
This is that lecture.
The most important hour you'll watch this week.
Bookmark it for later!
