# llm-wiki

This skill treats an Obsidian vault as a wiki: it ingests sources, updates entity and concept pages, keeps cross-references and a synthesis current.

## What it does

The agent becomes a steady wiki maintainer. You drop a paper, book or PDF into `raw/` and call `/wiki-ingest`; the agent reads it, talks the takeaways over with you, writes a summary page and revises the pages that source touches. Everything lands in `wiki/`, a folder the model owns and you read.

Three operations cover the loop. Ingest files a source. Query starts at `index.md`, follows links into the pages that matter and answers with citations, and a good answer can be filed back. Lint hunts contradictions, outdated claims, orphan pages and broken links.

The skill ships five slash commands (`/wiki-init`, `/wiki-ingest <path>`, `/wiki-query <question>`, `/wiki-lint`, `/wiki-log`), three sub-agents and eight scripts. Those scripts use the Python standard library alone, so there is nothing to pip install. `init_vault.py` builds the folder layout. Conventions sit in `CLAUDE.md` for Claude or in `AGENTS.md` for other agent CLIs; the repository carries both, yet the second one only does its job once you place it in the vault. A one-off question about a single document, with no Obsidian in the picture, is not the case for this skill.

## Requirements
- Works with: Obsidian

## Install

### Claude Code (native platform)

1. **Plugin marketplace**
In the agent chat (not a shell):
```text
/plugin marketplace add alirezarezvani/claude-skills
```
In the agent chat (not a shell):
```text
/plugin install llm-wiki@claude-code-skills
```
This installs the whole llm-wiki plugin with all its skills

2. **Skills CLI (Vercel)**
```bash
npx skills add alirezarezvani/claude-skills --skill llm-wiki -a claude-code
```

3. **Manually: put the files in place**
- File: `~/.claude/skills/llm-wiki/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/llm-wiki/

### Codex

**Manually: put the files in place**
- File: `.agents/skills/llm-wiki/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

**Manually: put the files in place**
- File: `.cursor/skills/llm-wiki/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install alirezarezvani/claude-skills llm-wiki
```

2. **Manually: put the files in place**
- File: `.github/skills/llm-wiki/SKILL.md`

### Gemini CLI

**Platform CLI**
```bash
gemini skills install https://github.com/alirezarezvani/claude-skills --path engineering/llm-wiki/skills/llm-wiki
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/llm-wiki/SKILL.md` — The legacy .windsurf/skills/ path still works

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/alirezarezvani/claude-skills/tree/HEAD/engineering/llm-wiki/skills/llm-wiki/SKILL.md

## When to use it
- keep every paper and book you read in one linked base
- catch sources that contradict each other on a regular check
- maintain person, org and concept pages with cross-references
- file a useful agent answer back into the wiki
- turn a wiki page into a slide deck with `export_marp.py`

## Example prompts
- Set up a vault on the topic of LLM interpretability
- Ingest `raw/anthropic-monosemanticity.pdf` into the wiki
- Check the wiki for how monosemanticity differs from mechanistic interpretability

# LLM Wiki — Second Brain for Claude Code + Obsidian

Inspired by Andrej Karpathy's LLM Wiki pattern ([gist](https://gist.github.com/karpathy/442a6bf555914893e9891c11519de94f)). This skill turns Claude Code (or any agent CLI) into a disciplined wiki maintainer that **incrementally builds and maintains** a persistent, interlinked Obsidian vault as you feed it sources. The knowledge compounds — cross-references, contradictions, and synthesis are already there when you query.

## Core principle

Most LLM+docs workflows are **RAG**: retrieve fragments at query time, synthesize from scratch, forget. The wiki is **compounding**: sources are read once, integrated into a persistent markdown knowledge base, and kept current. You curate and ask; the LLM reads, files, cross-references, and maintains.

> Obsidian is the IDE. The LLM is the programmer. The wiki is the codebase.

## When to use

- **Personal**: track goals, health, psychology, journaling, self-improvement
- **Research**: deep dives over weeks on a topic — papers, articles, reports, evolving thesis
- **Book companion**: file chapters as you read; build a fan-wiki-style companion for characters, themes, plot threads
- **Business/team**: internal wiki fed by Slack, meeting notes, calls — LLM does maintenance nobody else wants to do
- **Competitive analysis, due diligence, trip planning, course notes, hobby deep-dives**

**Do NOT use when:** you need one-shot Q&A over a fixed document (use RAG), you don't plan to add sources over time, or you don't want Obsidian in the loop.

## Architecture (three layers)

```

├── wiki/                   # Layer 2 — LLM-owned knowledge base
