The gist describes an agent that builds a structured personal wiki in markdown, integrating new sources by updating relevant pages and noting contradictions. His personal wiki runs ~100 articles and 400K words. The pattern works across Claude, ChatGPT, and Codex. Copy the gist and the agent bootstraps it. I've been doing something similar with my knowledge graph system, and the maintenance overhead is real, but the retrieval quality beats naive RAG by a wide margin.
