create-opc-wiki

Build your own personal LLM wiki in 30 seconds. Multi-agent native, MCP-ready, SEO/GEO-optimized publish target.

Inspired by Andrej Karpathy's "LLM Wiki" gist. This package is one concrete instantiation of that idea — opinionated about agent rules, directory ontology, frontmatter schema, privacy, and the publish pipeline. The idea is Andrej's; the implementation is this project's. Full credit and quoted lineage in INSPIRATION.md.

# Interactive
npx create-opc-wiki my-wiki

# Zero-prompt (any agent, any IM, any CI)
npx -y create-opc-wiki@latest ~/wiki --yes --agents=claude,codex,cursor,openclaw,hermes

That's it. Open the generated folder in Obsidian, fire up your AI agent, and start building your second brain.

Quickstart

npx create-opc-wiki my-wiki         # interactive prompts
cd my-wiki
# Open in Obsidian: File → Open Vault → this folder
# Or fire up Claude Code / Codex / Cursor and try /wiki-ingest <url>

What it scaffolds

A local-first knowledge base with three layers (per the Karpathy LLM Wiki pattern):

• raw/ — immutable source archive (articles, papers, chats, notes)
• wiki/<domain>/ — agent-compiled markdown, your synthesized knowledge
• agent-rules/main.md — single source of truth for agent behavior, synced to nine agent file formats

Plus:

• ✨ Multi-agent native — one rules file, synced to CLAUDE.md, AGENTS.md, .cursor/rules/main.mdc, .cursorrules, .github/copilot-instructions.md, .trae/rules.md, .openclaw/rules.md, .hermes/agent.md
• 🔌 MCP server built-in — three tools (wiki_query, wiki_list, wiki_read) with privacy enforcement at the boundary
• 📥 5 source recipes — arXiv papers, X threads, YouTube transcripts, RSS articles, podcast transcripts
• 🌐 SEO + GEO publish target — npm run wiki:publish produces an Astro Starlight site with sitemap.xml, llms.txt, robots.txt, RSS feed, OpenGraph + JSON-LD
• 🔒 Privacy-first frontmatter — public / private / secret levels; secret never leaves the box, private never publishes
• 🩺 Epistemic hygiene — confidence: high|medium|speculative with decay reminders for stale speculative claims
• 📚 Three reusable skills — /wiki-ingest, /wiki-query, /wiki-lint

Install in any AI agent (paste-in recipes)

The scaffolder is fully non-interactive when given --yes. Any agent that can run a shell command can install the wiki for you in one line. Per-agent recipes in docs/INSTALL-FOR-AGENTS.md.

Agent	One-liner (paste to the agent)
OpenClaw (IM)	npx -y create-opc-wiki@latest ~/wiki --yes --agents=openclaw,claude
Hermes-agent (IM)	npx -y create-opc-wiki@latest ~/wiki --yes --agents=hermes,codex
Claude Code	npx -y create-opc-wiki@latest ~/wiki --yes --agents=claude
Codex CLI / OpenCode / Pi	npx -y create-opc-wiki@latest ~/wiki --yes --agents=codex
Cursor	npx -y create-opc-wiki@latest ~/wiki --yes --agents=cursor
VSCode + Copilot	npx -y create-opc-wiki@latest ~/wiki --yes --agents=vscode
Trae IDE	npx -y create-opc-wiki@latest ~/wiki --yes --agents=trae

Or grab them all: --agents=claude,codex,cursor,vscode,trae,openclaw,hermes.

How it differs from RAG / NotebookLM / file uploads

Most LLM-on-files setups (NotebookLM, ChatGPT file uploads, raw RAG) re-derive answers from raw documents at every query. There is no accumulation. Quoting the original gist:

Instead of just retrieving from raw documents at query time, the LLM incrementally builds and maintains a persistent wiki — a structured, interlinked collection of markdown files that sits between you and the raw sources. The wiki keeps getting richer with every source you add and every question you ask.

This package operationalizes exactly that, with concrete choices for ontology, agent rules, MCP, and publishing.

CLI flags

Flag	Purpose
--name <s>	project dir name (or first positional)
--domains <csv>	knowledge domains (default: tech,finance,reading,growth,insights)
--agents <csv>	agent rule targets (default: claude,codex,cursor)
--mcp / --no-mcp	include MCP server (default yes)
--site / --no-site	include Astro static site target (default yes)
--recipes / --no-recipes	include source ingest recipes (default yes)
--git / --no-git	git init + first commit (default yes)
-y, --yes	accept all defaults, no prompts
--json	emit machine-readable result on stdout

FAQ

Q: Why a wiki instead of just RAG? A wiki compiles and reuses synthesis. RAG re-derives it on every query. See INSPIRATION.md for Karpathy's framing.

Q: Does my data leave the machine? No. The wiki is a local Obsidian vault. The MCP server runs locally over stdio. The static site only publishes pages with privacy: public in frontmatter.

Q: Which agent should I use? Any of the nine supported. Use --agents=claude,codex,cursor,openclaw,hermes to target several at once and edit agent-rules/main.md once for all of them.

Q: How is "GEO" different from "SEO"? SEO targets web search (Google, Bing). GEO = Generative Engine Optimization — making your content discoverable to LLM crawlers (ChatGPT, Claude, Perplexity). The published site emits both: sitemap.xml for SEO, llms.txt + structured prose for GEO.

Q: Will this stay stable across upgrades? Yes — see STABILITY.md. CLI flags, generated file paths, frontmatter schema, and MCP tool signatures are covered by semver. Template prose is not.

Q: Can I use this without npm/Node? Today, no. The scaffolder runs once via npx; after that the generated wiki is plain markdown and works without Node. The optional MCP server and Astro site need Node 20+.

On the road to OPC

OPC = One Person Company. Thesis: with AI, a single person can run what used to take a team. A maintained second brain is infrastructure for that. This tool is one of the building blocks.
