Claude Code and Obsidian turn 400 dead notes into a 2-second second brain
FinanceYF5 · x · 2026-07-22
A practical thread on turning a pile of dead notes into a usable second brain with Claude Code and Obsidian.
- The author says a vault with 400 notes can become a system that answers questions in about 2 seconds.
- The workflow is fully Markdown-based and stored on your own disk, so the data stays under your control.
- Part 1: clone the repo, run a setup script, open the folder as an Obsidian vault, then let /wiki scaffold the structure.
- Part 2: install it as a Claude Code plugin instead of cloning.
- Part 3: daily commands include ingesting sources into linked pages, asking the knowledge base questions, saving conversations into permanent notes, running autonomous research, and cleaning the wiki.
- Part 4: use MCP so Claude can read/write vault notes directly instead of copy-pasting.
- Part 5: point multiple Claude Code projects at the same vault so all work shares one knowledge base.
- Part 6: layer on Obsidian’s official agent skills so Claude writes proper wikilinks, callouts, and database views.
