Key Takeaways

  • Context files over repeated prompts: Instead of re-explaining projects each Claude Code session, create dedicated markdown files per project and reference them with a single command. Vin uses a slash context command that reads multiple files simultaneously — project descriptions, daily notes, and backlinked files — loading a complete personal context in seconds rather than minutes of re-explanation.
  • Obsidian CLI unlocks graph-aware AI: The Obsidian CLI passes not just file contents to Claude Code but also the relational graph between files — which notes link to which. This lets the agent detect cross-domain patterns across months of notes that a human cannot manually surface, such as recurring startup themes appearing across unrelated daily entries.
  • Custom slash commands automate daily operations: Vin builds commands like slash today (pulls calendar, iMessages, and a week of daily notes into a prioritized plan), slash close day (extracts action items and updates confidence ratings on hypotheses), and slash drift (compares stated intentions against actual behavior over 30 to 60 days of vault history).
  • Vault-generated idea reports replace manual brainstorming: Running a slash ideas command triggers Claude Code to scan the entire vault — orphaned notes, unresolved links, daily entries, project context files — and output a structured report covering tools to build, people to contact, essays to write, and systems to implement, all derived from the user's own existing writing.
  • Strict human-only writing rule preserves pattern integrity: Vin enforces a rule where Claude Code never writes directly into the Obsidian vault. If the agent populates files, pattern-detection commands conflate the agent's thinking with the user's own. Keeping all vault content human-authored ensures that when Claude Code surfaces patterns, those patterns reflect genuine personal thinking evolution.

What It Covers

Developer and creator Vin demonstrates how pairing Obsidian — a markdown-based note vault — with Claude Code creates a personalized AI thinking partner. By building custom slash commands that read interconnected files, users feed agents deep context about their life, projects, and patterns, enabling faster delegation and idea generation.

Notable Moment

Vin ran a slash trace command on his own Obsidian usage and the agent produced a 13-month chronological evolution of his relationship with the tool — pulling from dated daily notes — revealing a documented shift from skepticism about backlinks to building autonomous agent infrastructure, a history he could not have reconstructed manually.

Episode Transcript

This is Obsidian. And Obsidian is this little tool that people are using as their second brain. But what's really cool about it is they're pairing it with Claude Code, and they're getting crazy results out of it. It's literally a game changer. Now I've been slow to adopt Obsidian because to me, it's been a little daunting to look at. So I had my friend, Vin, and he clearly explains what Obsidian is, how to use it with cloud code, how to set up these commands that really drive the most out of Cloud and all the LLMs, and it's an incredible episode, like, a really game changing episode, because I think that people who understand how to use Obsidian and how to use Cloud Code together, they're going to be able to live happier, healthier, and wealthier lives. Why? Because it gives incredible ideas to you on tap. So I know that the people that stick around to the end of this episode, I think that for a lot of them, it's going to absolutely change how they use AI, and it's gonna be a super impactful way because you're gonna get better ideas at the right time, the right moment, and it's gonna make you happier, healthier, and wealthier. Enjoy the episode. I've got my dear friend, Vin, also known as Internet Vin, on the podcast. I literally begged him to come on. I I begged him. I begged this man to come on and to teach us a very specific thing. Vin, by the end of this podcast episode, what are people gonna learn? I want you to have an understanding of how you can use Cloud Code and Obsidian as a thinking partner. I want you to have an understanding of how you can stop, having to explain things to agents over and over again and just pass specific files in. And I want you to understand how you can use Obsidian Cloud Code to notice things about the way you think that you would not have noticed on your own without these tools. Alright. From your lips to God's ears. Let's get into it. Okay. So first is, like, what is Cloud Code? So Cloud Code is this, like, agent that you can use, in a command line interface. So it's just basically this tool you can use that you can control your computer and you can use it through natural language. Right? So I can say, make a file or make a file on my desktop that says, hello Greg in plain text. Right? And it's gonna go and do this. That's really cool. That's that's something that's that's new. That wasn't possible before. Before this, I had to go to the desktop, open some text editor, and then, like, create that file. Right? And now, this file is on my desktop. So I can say, open the file. There we go. Hello, Greg. That's crazy. Right? Now, what's interesting about this is …
