Jul 06, 2026 08:00 PM - 4 hours ago 193

My past portion connected Google’s Open Knowledge Format (OKF) was 1 of the astir celebrated I’ve ever published. Since then, I person been heads down moving connected my ain OKF structure. I’ve fundamentally built my ain individual brain, and today, I want to show you really it useful and why this modular is truthful incredibly important for the displacement toward an agentic web.

The beauty of OKF is that it follows a very simple, standardized structure. While galore group person pointed retired that markdown files are thing new, what Google has done is create a standard. This intends if I springiness an supplier my OKF files, it knows precisely really to publication them without needing civilization software. It is simply a cosmopolitan connection for AI agents.

Watch the video of maine showing my OKF brain:

Understanding The YAML Frontmatter, Index, And Markdown Files

Every OKF record starts pinch what is called YAML frontmatter. This is simply a mini artifact of metadata astatine the apical of your markdown record that tells an supplier precisely what it’s looking at. In my individual brain, I usage circumstantial types for everything. I person concepts, entities, playbooks, references, and systems.

Here is what my files building looks for illustration for my OKF brain:

And present is the markdown codification for 1 of the concepts successful my brain:

When an supplier views my OKF, it first views the scale file. This index.md record is fundamentally an scale of the different areas the supplier tin entree successful my brain. This way, alternatively of my supplier having to do RAG crossed everything successful my knowledge base, it tin attraction specifically connected the areas that are relevant.

The strategy I built besides useful to link related concepts. When it ingests a caller portion of content, whether it’s a blog station I’ve written, a Google announcement, aliases a portion of research, it finds what different concepts we person created that should beryllium connected. The consequence is simply a really cool chart of each of the knowledge we person successful the brain. This thought of agents extracting concepts and making connections comes from Andrej Karpathy’s LLM Wiki idea.

Visualizing Your Knowledge Graph

When you usage OKF correctly, you tin visualize your encephalon arsenic a connected graph. Every dot successful my strategy is simply a markdown file. You tin spot really my concepts for AI Overviews link to my references from Google’s archiving and my soul playbooks. It’s a living, breathing representation of everything I cognize astir SEO and AI.

I’m besides automating really I ingest information. I person a strategy that checks Google’s archiving daily. If they update something, for illustration the archiving connected AI Answers aliases Search Console features, my encephalon notifies maine and automatically updates the applicable reference files. I don’t person to trust connected my biologic hardware to retrieve each mini alteration anymore. My OKF encephalon has entree to acold much than I could ever support successful my caput astatine once.

I tin past query my brain, and it will constitute thing for maine that is synthesized from my notes and the different accusation I’ve chosen to shop successful my brain. If thing seems disconnected to me, past I tin simply inquire the supplier wrong my encephalon to correct it. Also, my supplier is ever looking for ways to amended and link the accusation that is successful the brain.

Building Playbooks To Save Days Of Work

One of the astir breathtaking things I’ve built successful my OKF encephalon is simply a group of playbooks. For example, I person a playbook for generating customer proposals. Usually, this is simply a tedious process that takes a batch of manual work. Now, my supplier (Antigravity) follows the steps laid retired successful my connection playbook to draught everything utilizing my circumstantial sound and logic.

I besides built a playbook for analyzing tract effect aft a Google update. I created a procedural checkpoint for my supplier to travel erstwhile analyzing these shifts. What utilized to return maine 2 days to analyse now takes a matter of hours, and the study produced is thing I’m incredibly happy with. This is the powerfulness of documenting your contented successful a measurement that agents tin really execute.

I really promote you to commencement experimenting pinch this. You don’t request to beryllium a coder to start. You tin show an supplier to thief you build your first OKF bundle based connected the archiving Google has provided. It’s making maine much productive, and I deliberation it’s the cardinal to staying applicable arsenic Search continues to evolve.

To build thing similar, springiness these links to your supplier (Claude Code / Cowork, ChatGPT Codex, aliases my favorite, Google’s Antigravity) and effort this prompt:

"I want to build an OKF strategy akin to Marie's. Read these links and past springiness maine immoderate ideas of what this would look like. Then, inquire maine questions 1 astatine a clip truthful that together, we tin determine what we want to build: https://cloud.google.com/blog/products/data-analytics/how-the-open-knowledge-format-can-improve-data-sharing/ https://github.com/GoogleCloudPlatform/knowledge-catalog/blob/main/okf/SPEC.md https://gist.github.com/karpathy/442a6bf555914893e9891c11519de94f https://www.mariehaynes.com/okf/ https://youtu.be/esYAIA6lU-s"
