Use Claude Code to manage a markdown second brain
Keep a git-backed markdown vault organized by asking Claude Code to answer questions, find notes, add files, and reshape folders.
- What they did
- A commenter set up a personal second brain as a repository of markdown files for projects, ideas, and writing. They then use Claude Code inside that folder every day to query the content, pull up documents, write new notes, and tidy the structure. Git keeps the repo in sync, and the same files are opened and edited in Obsidian.
- How it went
- They say the workflow has become a daily habit and that they really like it. The thread doesn’t give any usage stats or describe strict limits.
- Tips
- This works best when your notes live in plain markdown and are already organized in a git-synced folder. If you want the agent to move or delete anything, have it show the plan first and wait for your approval.
Try it yourself with Claude Code
You are working in my markdown knowledge base at [folder path], which is synced with git and also opened in Obsidian. Use the files as my personal second brain: answer questions from the notes, locate specific documents, draft new markdown notes, and suggest better ways to organize the folders. Before you move, delete, rename, or submit anything, show me the exact plan and wait for my approval. After I approve, make the changes and prepare a git commit message for me to review.
