Karpathy's LLM Wiki

Build and maintain a persistent, compounding knowledge base as interlinked markdown files.

Based on [Andrej Karpathy's LLM Wiki pattern](https://gist.github.com/karpathy/442a6bf555914893e9891c11519de94f).

Unlike traditional RAG (which rediscovers knowledge from scratch per query), the wiki

compiles knowledge once and keeps it current. Cross-references are already there.

Contradictions have already been flagged. Synthesis reflects everything ingested.

Division of labor: The human curates sources and directs analysis. The agent

summarizes, cross-references, files, and maintains consistency.

When This Skill Activates

Use this skill when the user:

• Asks to create, build, or start a wiki or knowledge base
• Asks to ingest, add, or process a source into their wiki
• Asks a question and an existing wiki is present at the configured path
• Asks to lint, audit, or health-check their wiki
• References their wiki, knowledge base, or "notes" in a research context

Wiki Location

Location: Set via WIKI_PATH environment variable (e.g. in ${HERMES_HOME:-~/.hermes}/.env).

If unset, defaults to ~/wiki.

WIKI="${WIKI_PATH:-$HOME/wiki}"

The wiki is just a directory of markdown files — open it in Obsidian, VS Code, or

any editor. No database, no special tooling required.

Architecture: Three Layers

wiki/
├── SCHEMA.md           # Conventions, structure rules, domain config
├── index.md            # Sectioned content catalog with one-line summaries
├── log.md              # Chronological action log (append-only, rotated yearly)
├── raw/                # Layer 1: Immutable source material
│   ├── articles/       # Web articles, clippings
│   ├── papers/         # PDFs, arxiv papers
│   ├── transcripts/    # Meeting notes, interviews
│   └── assets/         # Images, diagrams referenced by sources
├── entities/           # Layer 2: Entity pages (people, orgs, products, models)
├── concepts/           # Layer 2: Concept/topic pages
├── comparisons/        # Layer 2: Side-by-side analyses
└── queries/            # Layer 2: Filed query results worth keeping

Layer 1 — Raw Sources: Immutable. The agent reads but never modifies these.

Layer 2 — The Wiki: Agent-owned markdown files. Created, updated, and

cross-referenced by the agent.

Layer 3 — The Schema: SCHEMA.md defines structure, conventions, and tag taxonomy.

Resuming an Existing Wiki (CRITICAL — do this every session)

When the user has an existing wiki, always orient yourself before doing anything:

① Read SCHEMA.md — understand the domain, conventions, and tag taxonomy.

② Read index.md — learn what pages exist and their summaries.

③ Scan recent log.md — read the last 20-30 entries to understand recent activity.

WIKI="${WIKI_PATH:-$HOME/wiki}"
# Orientation reads at session start
read_file "$WIKI/SCHEMA.md"
read_file "$WIKI/index.md"
read_file "$WIKI/log.md" offset=<last 30 lines>

Only after orientation should you ingest, query, or lint. This prevents:

• Creating duplicate pages for entities that already exist
• Missing cross-references to existing content
• Contradicting the schema's conventions
• Repeating work already logged

For large wikis (100+ pages), also run a quick search_files for the topic

at hand before creating anything new.

Initializing a New Wiki

When the user asks to create or start a wiki:

1. Determine the wiki path (from $WIKI_PATH env var, or ask the user; default ~/wiki)

2. Create the directory structure above

3. Ask the user what domain the wiki covers — be specific

4. Write SCHEMA.md customized to the domain (see template below)

5. Write initial index.md with sectioned header

6. Write initial log.md with creation entry

7. Confirm the wiki is ready and suggest first sources to ingest

SCHEMA.md Template

Adapt to the user's domain. The schema constrains agent behavior and ensures consistency:

# Wiki Schema

## Domain
[What this wiki covers — e.g., "AI/ML research", "personal health", "startup intelligence"]

## Conventions
- File names: lowercase, hyphens, no spaces (e.g., `transformer-architecture.md`)
- Every wiki page starts with YAML frontmatter (see below)
- Use `[[wikilinks]]` to link between pages (minimum 2 outbound links per page)
- When updating a page, always bump the `updated` date
- Every new page must be added to `index.md` under the correct section
- Every action must be appended to `log.md`
- **Provenance markers:** On pages that synthesize 3+ sources, append `^[raw/articles/source-file.md]`
  at the end of paragraphs whose claims come from a specific source. This lets a reader trace each
  claim back without re-reading the whole raw file. Optional on single-source pages where the
  `sources:` frontmatter is enough.

## Frontmatter
  

---

title: Page Title

created: YYYY-MM-DD

updated: YYYY-MM-DD

type: entity | concept | comparison | query | summary

tags: [from taxonomy below]

sources: [raw/articles/source-name.md]

# Optional quality signals:

confidence: high | medium | low # how well-supported the claims are

contested: true # set when the page has unresolved contradictions

contradictions: [other-page-slug] # pages this one conflicts with

---

`confidence` and `contested` are optional but recommended for opinion-heavy or fast-moving
topics. Lint surfaces `contested: true` and `confidence: low` pages for review so weak claims
don't silently harden into accepted wiki fact.

### raw/ Frontmatter

Raw sources ALSO get a small frontmatter block so re-ingests can detect drift:

---

source_url: https://example.com/article # original URL, if applicable

ingested: YYYY-MM-DD

sha256: <hex digest of the raw content below the frontmatter>

---

The `sha256:` lets a future re-ingest of the same URL skip processing when content is unchanged,
and flag drift when it has changed. Compute over the body only (everything after the closing
`---`), not the frontmatter itself.

## Tag Taxonomy
[Define 10-20 top-level tags for the domain. Add new tags here BEFORE using them.]

Example for AI/ML:
- Models: model, architecture, benchmark, training
- People/Orgs: person, company, lab, open-source
- Techniques: optimization, fine-tuning, inference, alignment, data
- Meta: comparison, timeline, controversy, prediction

Rule: every tag on a page must appear in this taxonomy. If a new tag is needed,
add it here first, then use it. This prevents tag sprawl.

## Page Thresholds
- **Create a page** when an entity/concept appears in 2+ sources OR is central to one source
- **Add to existing page** when a source mentions something already covered
- **DON'T create a page** for passing mentions, minor details, or things outside the domain
- **Split a page** when it exceeds ~200 lines — break into sub-topics with cross-links
- **Archive a page** when its content is fully superseded — move to `_archive/`, remove from index

## Entity Pages
One page per notable entity. Include:
- Overview / what it is
- Key facts and dates
- Relationships to other entities ([[wikilinks]])
- Source references

## Concept Pages
One page per concept or topic. Include:
- Definition / explanation
- Current state of knowledge
- Open questions or debates
- Related concepts ([[wikilinks]])

## Comparison Pages
Side-by-side analyses. Include:
- What is being compared and why
- Dimensions of comparison (table format preferred)
- Verdict or synthesis
- Sources

## Update Policy
When new information conflicts with existing content:
1. Check the dates — newer sources generally supersede older ones
2. If genuinely contradictory, note both positions with dates and sources
3. Mark the contradiction in frontmatter: `contradictions: [page-name]`
4. Flag for user review in the lint report

index.md Template

The index is sectioned by type. Each entry is one line: wikilink + summary.

# Wiki Index

> Content catalog. Every wiki page listed under its type with a one-line summary.
> Read this first to find relevant pages for any query.
> Last updated: YYYY-MM-DD | Total pages: N

## Entities
<!-- Alphabetical within section -->

## Concepts

## Comparisons

## Queries

Scaling rule: When any section exceeds 50 entries, split it into sub-sections

by first letter or sub-domain. When the index exceeds 200 entries total, create

a _meta/topic-map.md that groups pages by theme for faster navigation.

log.md Template

# Wiki Log

> Chronological record of all wiki actions. Append-only.
> Format: `## [YYYY-MM-DD] action | subject`
> Actions: ingest, update, query, lint, create, archive, delete
> When this file exceeds 500 entries, rotate: rename to log-YYYY.md, start fresh.

## [YYYY-MM-DD] create | Wiki initialized
- Domain: [domain]
- Structure created with SCHEMA.md, index.md, log.md
