This is a weekly newsletter about running an Obsidian vault as an AI-powered second brain. It uses Claude Code as the agent, a knowledge graph for cross-references, and a small library of skills that compile, lint, and regenerate notes on demand. Everything runs locally on a real vault.
What you get
A single email each week. The subject line is the issue title. The body sits between 600 and 1200 words. No ads, no upsells in the middle of the issue, no AI-generated SEO mush.
The shape of every issue is fixed:
- What I built or fixed this week. A specific change to a specific skill, hook, or script. Diffs when they fit.
- What broke. The errors that cost real time, the dead ends I walked into, the tools that segfaulted.
- One thing worth borrowing. A pattern, a script, a snippet you can paste into your own setup.
If I changed a file, the file is named. If a tool crashed, the version is named. If a number is in the issue, it came from a real run.
What you don't get
No course pitches in the P.S.
I'm not running a course because I have a day job and I don't run cohorts. The only paid product is Starter ($99 on Gumroad): a zip of the same vault, the same skills, the same hooks. Download it, drop it into Obsidian, open it in Claude Code, hit a slash command, read your own notes back compiled.
Who's running this
An engineering practice lead at a Top-1% Microsoft Azure partner. Side project, evenings only. The vault has been my real second brain since late 2025.
Reply to this email if you want to share what you're building. I read most replies. I don't always answer fast.
Issue 01 ships next week. It's the LLM Wiki story.
