Second Brain OS：含 Jev 工程轨道的开源第二大脑仓库
作者把 800 万浏览的第二大脑系统打包成 MIT 仓库：18 个 agent 技能、72 条斜杠命令、6 个子代理，并单列 Jev engineering 与 loop engineering 学习轨道。
this is free f*cking gold for anyone building a second brain his second brain article pulled 8 million views, so he packed the whole system into one repo the repo, the guide, the tools, the learning path, all free • the guide > 10 sections, 65 pages, from the core idea to troubleshooting > 5 tracks on top, 44 pages, 15 of them build guides with working code • the machine (.claude/) > 18 agent skills, one per workflow > 72 slash commands - /ingest-pdf, /ingest-youtube, /ingest-voice, /backfill > 6 subagents - curator, linker, researcher, reviewer, ingestor, graph-analyst > 4 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/ stays untouched once it lands, wiki/ is what the agent keeps up > log.md - one line per run, so every change is traceable • 87 vetted resources > 28 tools, 26 Obsidian plugins, 15 repos, 12 skills, plus papers and articles five tracks to choose from: > 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 the Jev engineering and loop engineering tracks alone are worth the clone a consultant bills four figures to build you a research system like this. here it's a public repo under MIT ↳ https://github.com/undefined-ui/second-brain-os
