llmwiki-cli

A CLI tool for LLM agents to build and maintain personal knowledge bases.

Inspired by Andrej Karpathy's LLM Wiki.

Overview

The CLI is the hands -- it reads, writes, searches, and manages wiki files. The LLM is the brain -- it decides what to create, update, and connect.

LLM Agent (Claude Code / Codex)
|
| shells out to:
|   $ wiki init my-wiki --domain "machine learning"
|   $ wiki write wiki/concepts/attention.md <<'EOF' ... EOF
|   $ wiki index add "concepts/attention.md" "Overview of attention"
|   $ wiki search "scaling laws"
|   $ wiki lint
|   $ wiki commit "ingest: attention paper"
|   $ wiki push
|
v
wiki CLI (pure filesystem + git)
|
v
Wiki Repo (markdown files + .git + GitHub)

Key principle: The CLI never calls any LLM API. It is a pure filesystem + git tool.

Install

npm install -g llmwiki-cli

This gives you two commands: wiki (primary, 4 chars) and llmwiki (fallback if wiki conflicts).

Quick Start

# Create a new wiki
wiki init my-wiki --name "My Notes" --domain "research"

# Write a page
wiki write wiki/concepts/attention.md <<'EOF'
---
title: Attention Mechanism
created: 2025-01-20
tags: [transformers, NLP]
---
The attention mechanism allows models to focus on relevant parts of the input.
See also [[transformers]] and [[self-attention]].
EOF

# Add to index and log
wiki index add "concepts/attention.md" "Overview of attention mechanisms"
wiki log append ingest "Attention mechanism page"

# Search, lint, commit
wiki search "attention"
wiki lint
wiki commit "ingest: attention mechanism"

Wiki Structure

When you run wiki init, it creates:

my-wiki/
├── .git/
├── .llmwiki.yaml          # Wiki config
├── SCHEMA.md              # Instructions for LLM agents

How LLM Agents Use This

The generated SCHEMA.md in each wiki contains complete instructions. Here are the typical workflows:

Ingest a Source

# Save raw source
wiki write raw/paper.md <<'EOF'
<paste full text of paper>
EOF

# Create structured summary
wiki write wiki/sources/attention-paper.md <<'EOF'
---
title: Attention Is All You Need
created: 2025-01-20
tags: [transformers, attention, NLP]
source: https://arxiv.org/abs/1706.03762
---
Summary of the attention paper...
Links to [[transformers]] and [[self-attention]].
EOF

# Update bookkeeping
wiki index add "sources/attention-paper.md" "Attention Is All You Need (2017)"
wiki log append ingest "Attention paper"
wiki commit "ingest: attention paper"

Answer a Question

wiki search "attention mechanism"
wiki read wiki/concepts/attention.md
wiki links wiki/concepts/attention.md    # see related pages
wiki log append query "How does multi-head attention work?"

Maintain Wiki Health

wiki lint                  # find broken links, orphans, missing frontmatter
wiki orphans               # pages nobody links to
wiki status                # overview stats
wiki commit "maintenance: fix lint issues"

Sync to GitHub

wiki auth login            # one-time setup with GitHub PAT
wiki repo create research  # creates private wiki-research repo
wiki push                  # after making changes
wiki sync                  # pull + push

Multi-Wiki Support

The CLI supports multiple wikis via a global registry at ~/.config/llmwiki/:

wiki init ~/wikis/ml --name ml --domain "machine learning"
wiki init ~/wikis/personal --name personal --domain "personal notes"
wiki registry        # lists both
wiki use ml          # switch active wiki
wiki --wiki personal read wiki/index.md   # target specific wiki
wiki search "neural networks" --all       # search across all wikis

Wiki resolution order: --wiki flag > cwd .llmwiki.yaml > walk up directories > registry default.

Requirements

• Node.js >= 18 (or Bun)
• Git (optional but recommended for version control)
