用 Claude 子代理搭 Obsidian 第二大脑的开源仓库
一份免费 MIT 仓库，含 65 页指南、18 个 agent 技能、72 条斜杠命令和 6 个子代理，把 Karpathy 式 llm-wiki 知识库整套搬进 Obsidian。
ok this is the f*cking masterclass for building a Karpathy-style second brain in Obsidian, Zettelkasten included a second brain article pulled 8 million views, and the guy behind it packed the whole system into one free repo repo, guide, tools and learning path, all in one place • the guide > 10 sections and 65 pages, from first concept to troubleshooting > 5 extra tracks, 44 pages, 15 of them build guides with working code • the Zettelkasten part > raw/ is the inbox: sources land there and are never edited again > wiki/ holds the permanent notes the agent writes and links > the linker subagent does what Luhmann did by hand across 90,000 cards: ties every new note to the old ones • the machine (.claude/) > 18 agent skills, one per workflow > 72 slash commands, including /ingest-pdf, /ingest-youtube, /ingest-voice, /backfill > 6 subagents: curator, linker, researcher, reviewer, ingestor, graph-analyst > 4 of them are read-only, so nothing rewrites your vault behind your back • the scripts (plain Python, zero dependencies) > graph export, link checker, vault stats, chat converter, site builder • the starter vault > its own CLAUDE.md with page contracts and linking rules > raw/, wiki/ and log.md follow Karpathy's llm-wiki pattern > log.md writes one line per run, so every change stays auditable • 87 vetted resources > 28 tools, 26 Obsidian plugins, 15 repos, 12 skills, plus papers and articles five tracks once the basics click: > knowledge graphs > Jev engineering > agent harnesses > loop engineering > eval engineering new to this? start with the second brain guide. already deep in it? jump straight to the tracks consultants charge four figures to build a research system like this. here it sits in a public repo under MIT ↳ https://github.com/undefined-ui/second-brain-os
