Obsidian PARA Wiki

A Claude Code skill for building and maintaining a personal LLM knowledge base inside a PARA-structured Obsidian vault, with Quartz-compatible wikilinks.

Inspired by Karpathy's LLM wiki concept: the LLM writes and maintains the wiki; the human reads and asks questions. Adapted from the upstream karpathy-llm-wiki skill to fit PARA conventions.

What it does

Three operations on a sandboxed knowledge base under Resources/llm-wiki/:

Ingest — Fetch a source (URL or a file in 0-inbox/), save it as immutable raw material, then compile it into wiki articles. Cascade updates related articles, refresh the index, append to the log, and write a line into today's daily note Logs section.
Query — Search the wiki and synthesize an answer from existing articles. Optionally archive the answer as a new wiki page.
Lint — Auto-fix index drift, broken wikilinks, Quartz shortest-form violations; report orphan raw files, factual contradictions, missing cross-references.

Why it's different from upstream

Aspect	Upstream `karpathy-llm-wiki`	This skill
Directory layout	`raw/` and `wiki/` at project root	Nested under `Resources/llm-wiki/` (PARA Resources)
Link format	Standard markdown `[text](../../raw/x.md)`	Obsidian wikilinks `[[shortest-name]]`
Publishing compat	—	Compatible with Quartz `shortest` link resolution
Capture workflow	Direct URL ingest only	Also supports ingesting from `0-inbox/<file>.md`
File moves	Direct filesystem writes	Uses Obsidian CLI `move` to preserve wikilink integrity
Daily note	—	Appends a log line to today's daily note `# Logs` section
Orphan raw detection	—	Heuristic lint check for never-referenced raw files

Requirements

An Obsidian vault organized with PARA top-level directories (0-inbox/, Projects/, Areas/, Resources/, Archives/)
A daily note template with a # Logs section (at 0-inbox/daily/YYYY-MM-DD.md) — optional, skipped when absent
Obsidian installed at /Applications/Obsidian.app/ with Settings → General → Advanced → Command line interface enabled
Obsidian app running in the background (so the CLI can talk to it)
A Quartz-published vault or another consumer that respects shortest wikilink resolution (optional — the skill still works on non-published vaults)

Trigger words

Chinese: 加入知識庫、匯入到 wiki、我對 X 知道什麼、查詢知識庫、檢查 wiki、整理知識庫、PARA wiki、obsidian wiki、個人知識庫

English: add to wiki, ingest to wiki, what do I know about, query my wiki, lint the wiki, check wiki quality, PARA knowledge base

Usage examples

Ingest from a URL

User: 把這篇論文加入知識庫 https://arxiv.org/abs/2310.06825
AI:   Fetches content, writes raw/llm/2026-04-12-mistral-7b.md,
      compiles wiki/llm/mistral-7b.md (or merges into existing article),
      updates index.md and log.md, appends to today's daily note.

Ingest from 0-inbox

User: 把 0-inbox/mistral-notes.md ingest 到 llm-wiki
AI:   Reads the inbox file, writes raw/llm/mistral-notes.md,
      compiles the wiki article, then moves 0-inbox/mistral-notes.md
      to Archives/inbox-processed/mistral-notes.md via Obsidian CLI.

Query

User: 我的 wiki 裡關於 LoRA 有什麼內容？
AI:   Reads wiki/index.md, opens relevant articles, synthesizes an
      answer with [[article|Title]] citations. Does not write files
      unless you ask for an archive.

Lint

User: 幫我 lint 整個 wiki
AI:   Auto-fixes index drift, broken wikilinks, and path-prefixed
      wikilinks that violate Quartz shortest form. Reports orphan
      raw files, factual contradictions, and missing cross-references.

Design notes

Sandbox via Resources/: Keeping everything under Resources/llm-wiki/ means this skill coexists with whatever else lives in the vault without interfering with PARA Projects/Areas flows.
Wikilinks over standard markdown links: Ensures Quartz can publish the vault without broken links, and keeps the content navigable in Obsidian without round-trip rewrites.
Obsidian CLI for moves: Any rename or move goes through Obsidian move, which updates every wikilink in the vault atomically. Direct mv would silently break links.
Daily note integration: Writing to # Logs preserves your normal daily-note workflow (capture, review, summarize) without creating parallel activity streams.
