(If you're landing here directly: HQ is a personal productivity system built on markdown files, Claude Code, and a git repo. No apps, no databases, no infrastructure. The previous post covers why.) After ten weeks of daily production use, I can tell you exactly what made it work. Fifteen patterns. Most of them are the opposite of what I expected. 1.
