20,000 notes and ~400 skills: a 98-minute guide to Obsidian automation as an AI OS

dSebastien · x · 2026-08-19

Sébastien Dubois published "The Complete Guide to Obsidian Automation — From Templates to an AI Operating System," a 98-minute read covering his entire automation system built on a vault of 20,000+ notes and 400 skills, with the mental model of the vault as an operating system.

The guide is layered:

Core idea: an Obsidian vault is just plain-text Markdown files, so scripts, Git, cron jobs, and AI agents can all read and reason over it — making it a viable base layer for a personal AI "operating system." Because data stays local and under your control, none of this is possible with tools that lock notes in someone else's database.
