What I learned building with agents.

Building for ten people is different

Sunday Hype has maybe ten users. My kids are some of them. Building something useful for a small, specific audience turns out to be one of the more satisfying things I do.

RAG is not the same thing as knowledge

I built two RAG systems this year. One does document search. One extracts structured knowledge from documents. They're completely different products, and I conflated them for too long.

The build I didn't want to have to make

My nephew Brian died in an avalanche on February 22nd. I built the memorial site in a day, for the funeral on March 6th. Some things I'll remember about building it.

The first build I actually used

I built a chatbot that talks like my dad. It taught me more about persona prompting than anything I've read about it.
