AI Survival Guide:
Building Your Second Brain

Execution is commoditized — models have converged, and code is cheap. What remains scarce is your context: the judgment, patterns, and decisions only you have. This talk showed how a markdown Second Brain becomes the harness that makes AI work for you specifically — and why that is the one asset a WARN notice can't revoke.

실행은 흔해졌습니다. 남는 moat는 나만의 컨텍스트 — LLM 시대엔 그것이 나를 위해 AI를 작동시키는 harness가 됩니다.

Tonight's links

00 · Measure first
AKM Index — score your system
Before AI sorts you, measure yourself: install the akm-eval skill and your agent scores your knowledge system against 5 pillars × 25 evidence-based criteria (0–100, fully local, submission optional). Live public board included. 내 시스템 점수 측정 · 공개 보드.
01 · Starter kit
CMDS LLM Wiki template
Karpathy's LLM Wiki pattern as an Obsidian starter kit — schema files, slash commands, dual Claude Code/Codex harness. 볼트가 아직 없다면 오늘 밤의 시작점.
02 · System files
system.cmdspace.work
The open spec behind the 10,000-note vault you saw on stage — CLAUDE.md, AGENTS.md, rules, and a downloadable ZIP. 오늘 본 CLAUDE.md 체계 공개본.
03 · Newsletter (Korean)
더배러 The Better
The serialized version of tonight's argument — knowledge management × generative AI, in Korean. 이 이야기의 연재판.

05 · App I ship
CmdMD — macOS markdown editor
A native Swift/SwiftUI markdown editor I built — review-first, made for reading agent-written notes, with vault routing, templates, and quick capture. 직접 만들어 배포 중인 macOS 마크다운 에디터.
06 · Multi-agent
9Yohan — agent constellation
Nine division agents orchestrated on top of the same vault you saw tonight — how one knowledge system runs a team of agents. 볼트 위에서 도는 9-에이전트 오케스트레이션.
07 · Starter kit #2
CMDS vault template
The 9-category CMDS framework behind the 10,000-note vault, packaged as an Obsidian starter vault. CMDS 프레임워크 스타터킷.
08 · Monthly meetup
월간옵시디언 — Monthly Obsidian
The Korean-language monthly online meetup I run on Obsidian × AI — join from any timezone. 매달 여는 온라인 밋업 — 미국에서도 참여 가능.

Tonight: measure first, then one step

STEP 0Already running a vault + agent? Measure it first: grab akm-eval from akm.cmdspace.work — your agent runs the assessment locally (10–60 min) and hands you a scorecard. 이미 볼트가 있다면 측정부터.
STEP 1Make one folder of markdown files — file over app. Move tonight's notes into it.
STEP 2Write one CLAUDE.md at the root: who you are, what lives where, what the agent may touch. That single schema file is the fork in the road.
STEP 3Point Claude Code (or any agent) at the folder and ask it something only your notes can answer. Compare with vanilla chat — that difference is your harness.
