Brief

Obsidian's creator shipped an agent skills system (published 2026-06-05) that lets Claude-family models natively read, write, and reason inside vaults — creating .base and .canvas files, controlling the vault via obsidian-cli, and preserving plain Markdown. Key packages (obsidian-markdown, obsidian-bases, json-canvas, defuddle) are MIT-licensed, installable with 'npx skills add', and drew ~27,000 stars in days.

Source evidence

Most second brains are write-only. You save notes for years, then never find them again.

An agent that can actually work inside your vault changes that:

  1. Skills over plugins: Claude learns Obsidian syntax natively, wikilinks, embeds, callouts, properties.
  2. It writes .base files for you, real database views across your notes with zero manual setup.
  3. The agent can read, write, and reason inside the vault, not just answer questions about it.
  4. Files stay plain markdown on your disk, so there is no lock-in and nothing to migrate.
  5. 27,000 GitHub stars in days, the demand was already there.

A vault you can search is a library. A vault an agent can edit is a teammate.

THE CREATOR OF OBSIDIAN JUST TURNED YOUR NOTE VAULT INTO AN AI AGENT.

Not a plugin.

Not an integration.

A full agent skills system that teaches Claude Code, Codex, and OpenCode to READ, WRITE, and REASON inside your Obsidian vault like a power user.

27,000 GitHub stars in days.

Here is what shipped at launch:

obsidian-markdown — wikilinks, embeds, callouts, properties, the full Obsidian flavor Claude now understands natively.

obsidian-bases — Claude can create .base files with views, filters, formulas, and summaries.

json-canvas — Claude builds .canvas files with nodes, edges, groups, and connections.

obsidian-cli — Claude controls your vault, develops plugins and themes directly from the terminal.

defuddle — strips web pages into clean Markdown so you stop burning tokens on clutter.

Install the whole thing in one line:

npx skills add github.com/kepano/obsidian-s…

Then connect it to Claude Code, Codex, or OpenCode.

That is it.

Your second brain now has an agent inside it that understands how Obsidian actually works.

Not a generic AI that pastes text into files.

An agent that knows what a wikilink is. What a callout is. What a canvas is.

Built on the open Agent Skills spec. MIT license. Free forever.

The gap between people using Obsidian as a note app and people using it as an AI operating system just got wider.
