LLM-Kasten: a structured, persistent MD wiki CLI for agents

https://github.com/jordan-gibbs/llm-kasten

I got really tired of bloated knowledge bases with folders of unstructured MD files, so, inspired by the "Zettelkasten" and Karpathy's recent tweet, I created an open-source agent-forward CLI tool.

The goal here is to create expansive repositories of information that are fully linked, tagged, and quality assured. This way, when you tell an agent to "find this info" you can actually be certain it'll go to the right place. Docs are auto-injected into your agents/claude.md files so you can plug and play.

I was able to do a massive deep research session (7+ hours) where Claude Code with web search indexed all major LLM architecture advancements in 2025/2026, and auto-organized into a beautiful wiki spanning over 1 million words and 600 notes.

I'd love to hear if this is useful for anyone.
