My LLM wiki started to rot, so I gave it one rule

TL;DR
A Markdown wiki maintained by an agent beats RAG for one person’s work knowledge. It still rots, because agents append by default and the same fact ends up in three versions. The fix is to classify every fact as a state (replace it in place, with a date) or an event (append only), and to enforce that with a hook and an audit, not with a polite instruction.

For two months I have kept a knowledge base about my work that I almost never write myself. Claude Code reads my mail, meeting transcripts, calendar and shared documents every morning, then updates a folder of Markdown pages: one page per client, project, idea and person, plus a task list and a one-page dashboard. I read it in Obsidian and ask it questions.
