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 https://t.co/mHDEvCNOIC
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.

@_MaxBlade I honestly just act like a middle man between my max plan opus 4.7 “tuned to act more like 4.6” inside a project and my Openclaw sonnet orchestrating codex for executing/ perplexity for research. Was hitting $5-$15 with opus in Openclaw now Pennie’s - $1.50 with sonnet.
“Opus 4.7 you talk too much.”
I had to tell it “Commit fast, fix if wrong. Speed of decision + low reversal cost = momentum. Don't run like a careful engineering organization or you’ll miss the whole point”.
I think I’ve found my Openclaw setup sweet spot.
Openclaw setup:
- Sonnet orchestrates, crons
- Codex codes
- Haiku heartbeats
Claude max x20
- Create like project
- project knowledge: update readme.md often daily/weekly
- opus 4.7 oath for prompting Openclaw
Tips:
1. Stay as the driver, sonnet executes, you decide.
2. Speed of decision + low reversal cost = momentum
3. Phase large builds, smaller scopes, verify between
4. Plain English beats eng. theater
5. Route prompts through opus via projects. Flat rate planning, mtrd execution
FINALLY, a legit article that breaks this down in detail.
Obsidian + Claude Code = an AI that actually knows your work.
Not a generic chatbot. A real assistant with memory.
@cyrilXBT nailed it.
Most of the "agents keep breaking" problems come from one model trying to do everything with no guardrails. Separate the thinking from the coding from the research, give it persistent memory, and make it ask before it acts. Been running stable since.
- Phase gates. It builds in phases, stops at each checkpoint, and doesn't move forward without approval. No freestyling.
- A cron job runs a daily self-review at 3am. What it built, what broke, why. A second job at 3:30 checks if the first one ran. It learns from itself.
