Karpathy described the LLM-compiled-wiki pattern. Matt Wolfe extended it with Journal + CRM and built it on stream. We use Claude Code (not Codex) and wire the same vault you set up in Step 5. Same Obsidian frontend; same agents.md control file; ~30 min to working.
Attribution. The canonical spec is Andrej Karpathy's LLM Wiki gist — read it first; everything else here is implementation. The Wiki + Journal + CRM extension and the step-by-step build is from Matt Wolfe's video. We adapt the build to Claude Code and the same vault you set up in Step 5.
Articles, YouTube transcripts, podcast notes, tweets — anything you find on the web. Compiled by an LLM into entity / concept / tools / themes pages with backlinks. Auto-linked, zettelkasten-style.
Lives at corpus/ (company SOPs) + personal-brain/wiki/ (web saves). Already part of the framework's Step 5.
Write 'journal' to start a chat with Claude Code. Replies are grounded in your wiki, past journal entries, AND your CRM — not generic LLM advice. Files saved as journal/<date>-<slug>.md.
Optional Step 5 sub-action. The journal/ folder + agents.md rules generate themselves the first time you ask.
One Markdown file per person under CRM/. Tell Claude Code who you met + where + when + any notes. Later: 'where did I meet Matthew Berman?' returns the answer instantly.
Optional Step 5 sub-action. Same vault, same pattern, separate folder.
Assumes you have Obsidian + Claude Code installed (covered in Step 4 + Step 5). Same vault you already set up.
Either path works. The Personal Brain folders (raw/, wiki/, journal/, CRM/) coexist alongside your company SOPs in corpus/ — they don't conflict.
Claude Code runs against the current directory. Once it's pointed at the vault, every command operates on those files.
cd ~/BeBrain/<your-vault> claude
One prompt. Claude builds raw/, raw/processed/, wiki/, agents.md, index.md, log.md following Karpathy's spec.
Build out the wiki architecture in this Obsidian vault following Karpathy's
LLM wiki pattern:
- raw/ — inbox folder (Web Clipper drops files here)
- raw/processed/ — files that have already been ingested
- wiki/ — AI-compiled .md pages (entities, concepts, tools, themes), with [[backlinks]]
- agents.md — operations spec:
INGEST: read files from raw/, write/update wiki + index + log,
then move source to raw/processed/. For YouTube clips,
extract the channel name and add it to the source's frontmatter.
QUERY: search the vault index first; ground every answer in pages
you find there; if a relevant wiki page is missing, draft one
and add it to the index.
- index.md — table of contents for every wiki page
- log.md — append-only row per agent actionOne-click capture of any article or YouTube transcript → drops it into your vault's raw/ folder. Configure it to point at your vault, set the destination folder to raw/, tag with web-clip.
Clip 3-5 things you've recently watched / read. Then ask Claude to compile.
Process any new files in raw/ following agents.md. Move processed files to raw/processed/.
Open Obsidian to watch wiki pages appear, the index update, and log entries pile up.
Extends agents.md with two more rules: chats starting with journal get saved as dated entries; details about people get filed into CRM/<name>.md.
Update agents.md with two new operations: JOURNAL: when a chat starts with the word "journal", save the entire conversation as journal/<YYYY-MM-DD>-<slug>.md. Reply must be grounded in (a) wiki pages, (b) past journal entries in journal/, (c) CRM records. Append to journal/index.md with date + 1-line summary. CRM: when I say "add to CRM" followed by a person's details, create or update CRM/<person-name>.md with their summary. Maintain CRM/index.md with name + 1-line bio, alphabetical order.
Same LaunchAgent we use for the Obsidian Git auto-sync. One-line script that runs Claude Code in non-interactive mode against the vault. Anything new in raw/ gets compiled without you touching the terminal.
#!/usr/bin/env bash cd "$HOME/BeBrain/<your-vault>" || exit 1 claude --no-tty "Process any new files in raw/. Update wiki, index, log per agents.md. After processing, commit and push to origin/main with message: \"vault: AI sync $(date '+%F %T')\""
Matt builds this in Codex. Everywhere he says "Codex", you can substitute Claude Code with the same prompt — same files, same architecture, same outcome.
