karpathy-wiki Skill

When to use

When working with an LLM wiki (Karpathy pattern) - ingesting sources, querying, linting, or building the knowledge graph.

What it does

Enforces the exact Karpathy LLM Wiki pattern from https://gist.github.com/karpathy/442a6bf555914893e9891c11519de94f

Pattern Requirements

Directory Structure (MUST FOLLOW EXACTLY)

llm_wiki/
├── raw/              # Immutable source documents (NEVER edit these)
├── wiki/             # LLM owns this layer entirely - single source of truth
│   ├── index.md      # Catalog of ALL pages with curated one-line summaries
│   ├── log.md        # Append-only chronological record (format: ## [YYYY-MM-DD] operation | title)
│   ├── overview.md  # Living synthesis across all sources
│   ├── sources/      # Source summary pages (kebab-case.md)
│   ├── entities/    # Entity pages (TitleCase.md - people, companies, projects)
│   ├── concepts/     # Concept pages (TitleCase.md - ideas, methods, theories)
│   └── syntheses/   # Saved query answers
└── (no root-level wiki files - ALL must be under wiki/)

Frontmatter (REQUIRED on every page)

---
title: "Page Title"
type: source | entity | concept | synthesis
tags: []
sources: []      # list of source slugs that inform this page
last_updated: YYYY-MM-DD
---

Page Naming

• Sources: kebab-case (e.g., json-display-bugs-analysis-report.md)
• Entities: TitleCase (e.g., PR278.md, OpenAI.md, SamAltman.md)
• Concepts: TitleCase (e.g., StructuredResponse.md, RAG.md)

Wikilinks

Use [[PageName]] for internal links - these become the knowledge graph edges.

Index Format

# Wiki Index

## Overview
- [Overview](overview.md) — one-line synthesis

## Sources
- [Source Title](sources/slug.md) — CURATED one-line summary (NOT raw email subject)

## Entities
- [Entity Name](entities/EntityName.md) — one-line description

## Concepts
- [Concept Name](concepts/ConceptName.md) — one-line description

## Syntheses
- [Analysis Title](syntheses/slug.md) — what question it answers

Log Format

## [YYYY-MM-DD] operation | title

Key claims: ...

Operations: ingest, query, lint, graph

Ingest Workflow

1. Read source document from raw/
2. Read wiki/index.md and wiki/overview.md for context
3. Write wiki/sources/<slug>.md with Source Page Format
4. Update wiki/index.md — add entry under correct section
5. Update wiki/overview.md — revise synthesis
6. Create/update entity pages for key people/companies/projects
7. Create/update concept pages for key ideas/methods
8. Flag any contradictions
9. Append to wiki/log.md

Source Page Format

---
title: "Source Title"
type: source
tags: []
date: YYYY-MM-DD
source_file: raw/...
sources: []
last_updated: YYYY-MM-DD
---

## Summary
2–4 sentence summary.

## Key Claims
- Claim 1
- Claim 2

## Key Quotes
> "Quote here" — context

## Connections
- [[EntityName]] — how they relate
- [[ConceptName]] — how it connects

## Contradictions
- Contradicts [[OtherPage]] on: ...

Query Workflow

1. Read wiki/index.md to find relevant pages
2. Read those pages
3. Synthesize answer with [[PageName]] citations
4. Offer to save as wiki/syntheses/<slug>.md

Lint Workflow

Check for:

• Orphans: pages with no inbound [[links]]
• Broken links: [[WikiLinks]] to non-existent pages
• Contradictions: conflicting claims across pages
• Stale summaries: pages not updated after newer sources
• Missing entities: entities mentioned 3+ times without own page
• Missing concepts: concepts discussed without own page
• Data gaps: questions wiki can't answer

Graph Workflow

1. Grep all [[wikilinks]] → deterministic EXTRACTED edges
2. Infer implicit relationships → INFERRED edges with confidence
3. Run Louvain community detection
4. Output graph/graph.json + graph/graph.html

Common Issues to Fix

Dual Structure Problem

If wiki exists in both root AND wiki/ subdirectory:

• Move all wiki content to wiki/ subdirectory only
• Delete root-level index.md, log.md, overview.md if duplicates exist
• Update ingest.py to write to wiki/ subdirectory

Index Quality Problem

If index contains raw email subjects instead of curated summaries:

• Re-ingest with instruction to create proper summaries
• Edit index entries to be content-oriented, not raw titles

Entity/Concept Gap

If few entity/concept pages created:

• Force extraction: prompt must explicitly create entity pages for EVERY person/company/project mentioned
• Force extraction: prompt must explicitly create concept pages for EVERY idea/method/theory
• Track entity/concept ratio - should be roughly 1:1 with sources or higher
