I've been running a personal wiki system for a while. When Karpathy posted his LLM Wiki pattern I realized I'd been building toward the same thing, so I adapted what I had into a git template. It adds a metadata standard (every file has a header so the AI can scan by summary without loading full documents), a lint pass for stale content, and some other scaffolding on top. Still just a folder of markdown files - no app, no account, you own everything. Happy to answer questions about any of the design decisions.
