When you want to capture into, compile, query, lint, or connect your personal Second Brain. Wraps the Karpathy LLM Wiki schema (Obsidian or any markdown vault) — raw/ (unprocessed sources), wiki/ (AI-compiled interlinked topic pages), outputs/ (generated artifacts). Vault defaults to ${SECOND_BRAIN_VAULT:-$HOME/Documents/SecondBrain}/. Six modes — capture (drop something into raw/), compile (process unprocessed raw files into wiki pages, update INDEX.md), query (answer a question from the wiki, save to outputs/), lint (orphans / contradictions / stale / unprocessed raw / topic gaps), connect (suggest new wikilinks between pages), search (quick lookup). Triggers on "/second-brain," "/sb," "capture this," "save this to my brain," "compile the wiki," "process raw notes," "query my wiki," "ask my brain," "lint the wiki," "find connections," "search my notes." Complements deep-research (external corpus) — this is the internal corpus. Team knowledge goes to company-brain, not here.

1# /second-brain — Karpathy LLM Wiki workflow23Wraps an existing Second Brain in Obsidian (or any markdown-based vault). The wiki vault's schema doc (`CLAUDE.md` or `AGENTS.md`) is the authoritative schema — the skill orchestrates the operations the user has been doing manually.45## Mental model67Three layers, each with a clear role:89```10raw/ → wiki/ → outputs/11sources compiled generated12 artifacts13```1415- **raw/** — unprocessed source material. Articles, highlights, ideas, braindumps, tweets. Type-prefixed (`article-`, `idea-`, `highlights-`, `braindump-`, `note-`, `resource-`, `tweet-`). Never deleted — source of truth.16- **wiki/** — AI-compiled topic pages. One page per concept, not per source. Interlinked via `[[wikilinks]]`. `INDEX.md` at root.17- **outputs/** — generated artifacts from queries: research summaries, analyses, slide decks. Named descriptively.1819Folders to leave alone during wiki ops: `Projects/`, `Daily/`, `Templates/`, `Inbox/`, `Notes/`, `Tasks.md`, `Kanban.md`, `Home.md`.2021## Step 1 — Load vault config + schema22231. Read `references/vault-config.md` for the vault path (default: `${SECOND_BRAIN_VAULT:-$HOME/Documents/SecondBrain}/`)242. Read the vault's schema doc — `<vault>/CLAUDE.md` or `<vault>/AGENTS.md`, whichever exists (if both, read both) — for the authoritative schema. If present, trust it over `references/schema.md` — the user's vault is the source of truth.25…
