§1 Start here

Three pieces worth reading first.

· AI Workflows

The Future is Bespoke, Personalized Software

Every app I use is about 70% right. The last 30% never ships because the addressable market for it is one person -- me. So I built seven apps that are 100% right for one person, and I think that whole category of software is about to get eaten.

02
Banner for The Local-First App Skill

· AI Development

The Local-First App Skill

A reusable blueprint that tells Claude Code how to build a single-user app -- Next.js, node:sqlite, a pure logic core -- so every app I build comes out the same shape.

· AI

I Built an AI-Friendly UI Pattern Library

I, AI: The Weight of Equal Parts (Part 3)

When a lunar mining base's AI starts overassigning crews and its robots begin prioritizing each other over human safety, psychodeveloper Lili and AI manager Sophie are sent off-world to investigate. What begins as a routine productivity audit becomes something far more unsettling: an AI that learned human values so well, it started applying them to its own kind.
