Llm Wiki

LLM Wiki — Karpathy Knowledge Base Pattern

Experimental skill — iterating. Authored by Lewis Liu (lylewis@outlook.com) · Inspired by Karpathy's llm-wiki Gist

Core idea

Instead of RAG (re-retrieving raw docs on every query), the LLM compiles raw sources into a persistent, cross-linked wiki. Every ingest, query, lint, and audit pass makes the wiki richer. Knowledge compounds — and the human stays in the loop via a structured feedback channel instead of ad-hoc corrections that get lost.

• You own: sourcing raw material, asking good questions, steering direction, filing feedback on anything the AI got wrong.
• LLM owns: all writing, cross-referencing, filing, bookkeeping, and acting on your feedback.

The wiki is a living artifact with five operations — compile, ingest, query, lint, audit. Every session starts by reading CLAUDE.md and wiki/index.md.

CLAUDE.md is the schema file — the single most important configuration. It tells the LLM the wiki's scope, naming conventions, current article list, open questions, and research gaps. Read references/schema-guide.md for what to put in it. Read it at the start of every session.

Core principles

Four rules govern everything below. If a future instruction contradicts one, flag it to the user before acting.

1. Divide and conquer

A single concept page should never try to cover a complex topic end-to-end. Target: 400–1200 words per page. When a topic would blow past that:

• Create a subfolder: wiki/concepts/<topic>/
• Put a short index page at wiki/concepts/<topic>/index.md — definition, list of sub-pages, one-line summaries
• Put each aspect in its own file: wiki/concepts/<topic>/<aspect>.md
• In wiki/index.md, show the hierarchy via indented bullets

Example layout (from a real wiki):

Copy code
wiki/tech/claude-code/
├── index.md                         (overview + links to sub-pages)
├── Claude_Code_Architecture.md
├── Claude_Code_Agent_Framework.md
├── Claude_Code_Bridge_System.md
├── Claude_Code_Query_Engine.md
├── Claude_Code_Skills_Plugins.md
├── Claude_Code_State_Management.md
└── Claude_Code_Tool_System.md

One fat file covering all seven aspects would be unreadable and unlinkable. Seven focused files + an index page give you navigation, selective reading, clean backlinks, and small audit targets.

2. Mermaid for diagrams, KaTeX for formulas

• Any flow, sequence, hierarchy, or state diagram must be written in mermaid — never ASCII art. ASCII boxes rot fast and are impossible to annotate.

  Copy code
  ```mermaid
  flowchart LR
      A[raw/article.md] --> B[summary]
      B --> C[concept page]
      C --> D[index.md]
  ```
  

• Any formula must be written in KaTeX: inline $f(x) = \sum_i w_i x_i$ or block $$...$$.

Both render in the web viewer (server-side KaTeX, client-side mermaid) and in Obsidian with default settings.

3. Raw file policy

Small text-based sources (md, txt, small pdfs, small images) → copy into raw/<subfolder>/.

Large binaries (videos, model weights, installers, datasets, large PDFs >10 MB) → do not copy. Instead:

• Create a pointer file at raw/refs/<slug>.md with:

  yamlCopy code
  ---
  kind: ref
  external_path: /Volumes/external/models/llama-3-70b/
  size: ~140 GB
  ---
  

  followed by a short description of what it is and why it matters to this wiki.
• Wiki pages cite [[raw/refs/<slug>]] exactly like any other source.

This keeps the wiki repo git-friendly and portable.

4. Audit is the human feedback surface

The wiki is AI-written; it will be wrong sometimes. The raw sources are human-written; they will contradict each other. The audit/ directory is how humans correct both without losing the corrections in chat history.

• Humans file feedback via the Obsidian plugin or the web viewer. Each feedback is one file in audit/ with YAML frontmatter (anchor, target, severity) and a markdown body.
• The AI must periodically run the audit op — never silently ignore audit/*.md files.
• When feedback is applied, the file moves to audit/resolved/ with a # Resolution section appended and a log entry recorded in log/YYYYMMDD.md.

See references/audit-guide.md for the full file format and processing workflow.

The five operations

Every action on the wiki is one of these five. Each appends an entry to the current day's log file (log/YYYYMMDD.md).

1. compile

(Re)structure wiki content from existing raw/ material — including splitting oversized pages, merging near-duplicates, and rebuilding index.md.

When to run: after a big ingest batch, when an existing page has outgrown 1200 words, when index.md no longer reflects reality, or when the user says "clean up the wiki".

Steps:

1. Read CLAUDE.md, wiki/index.md, and every file in the target subtree.
2. For each page over ~1200 words: plan a split into concepts/<topic>/ with an index + sub-pages. Confirm the plan with the user before writing.
3. For each pair of near-duplicate pages: propose a merge. Confirm, then rewrite.
4. Regenerate wiki/index.md so every page is listed exactly once.
5. Log: ## [HH:MM] compile | <what you did — files touched, splits, merges>

2. ingest

Add a new source. One source typically touches 5–15 wiki pages.

Steps:

1. Save source to the right subfolder:
   • web article → raw/articles/<slug>.md
   • paper → raw/papers/<slug>.md (extracted text for big PDFs)
   • note → raw/notes/<slug>.md
   • large binary → raw/refs/<slug>.md pointer file (see raw file policy)
2. Read the source in full.
3. Create wiki/summaries/<slug>.md (200–400 words — key takeaways, not a rewrite; see references/article-guide.md).
4. Create or update relevant concept pages in wiki/concepts/. Respect divide-and-conquer: if a concept page would exceed 1200 words, split instead of cramming.
5. Create or update entity pages in wiki/entities/ for any new people / tools / papers / organizations referenced.
6. Update wiki/index.md so the new pages appear under the right category.
7. Log: ## [HH:MM] ingest | <slug> — <one-line description> (touched N pages)

3. query

Answer a question grounded in the wiki, not general knowledge.

Steps:

1. Read wiki/index.md. Scan for relevant pages by category.
2. Read the identified pages in full; follow one level of wikilinks.
3. If the wiki doesn't have enough material, say so and suggest what to ingest next instead of making something up.
4. Synthesize the answer, citing pages inline with [[Page Name]].
5. Save to outputs/queries/<YYYY-MM-DD>-<question-slug>.md.
6. If the answer is durable (a comparison, analysis, or new synthesis) → promote a cleaned-up version to wiki/concepts/, add to index.md.
7. Log: ## [HH:MM] query | <question-slug> (and a separate ## [HH:MM] promote | ... line if promoted).

4. lint

Health check. Run:

bashCopy code
python3 scripts/lint_wiki.py <wiki-root>

The script reports:

• Dead wikilinks — [[Target]] where Target.md doesn't exist
• Orphan pages — pages with no inbound wikilinks
• Missing index entries — pages not listed in wiki/index.md
• Frequently-linked missing pages — [[X]] referenced 3+ times but no page
• log/ shape — stray files or wrong filenames in log/
• audit/ shape — malformed YAML frontmatter in audit/*.md
• Audit target resolution — every open audit's target file must exist

For each issue, propose a fix, confirm with the user, then apply. Log: ## [HH:MM] lint | <N> issues found, <M> fixed.

5. audit

Process human feedback from audit/.

Steps:

1. Run python3 scripts/audit_review.py <wiki-root> --open to get a grouped list.
2. For each open audit, read the file. Use the anchor_before / anchor_text / anchor_after window to locate the exact range in the target file (line numbers may have drifted).
3. Decide the action:
   • Accept: apply the correction to the target file.
   • Partially accept: apply what makes sense, note the rest in the resolution.
   • Reject: explain why in the resolution — the feedback may be based on a misreading of scope or a contradictory source.
   • Defer: add to CLAUDE.md "Open research questions" and leave the audit in place with a comment.
4. For applied audits, append a # Resolution section to the audit file:

   markdownCopy code
   # Resolution
   
   2026-04-10 · accepted.
   Fixed the file count (was "~1,900", corrected to "~1,800" per commit abc123).
   Updated: tech/Claude_Code.md lines 47–48.
   

5. Move the file from audit/ to audit/resolved/. Filename unchanged.
6. Log per resolved audit:

   Copy code
   ## [HH:MM] audit | resolved 20260409-143022-a1b2 — <one-line what>
   

7. Never delete audit files. Rejected ones still go to resolved/ with the rejection rationale in their resolution section — that's valuable history.

See references/audit-guide.md for the full audit file format.

Tooling

The Obsidian plugin and the web viewer both write audit files in the same format with the same anchor algorithm, so feedback filed from either place can be resolved by either place.

Starting a new wiki

bashCopy code
python3 scripts/scaffold.py <wiki-root> "<Topic Title>"

Creates the full tree (including log/<today>.md, audit/, audit/resolved/), a blank CLAUDE.md based on the new template, and a blank wiki/index.md with the recommended category layout.

After scaffolding:

1. Fill in CLAUDE.md — define scope, naming conventions, initial research questions.
2. Start ingesting sources.
3. Ask questions to build up outputs/queries/; promote durable answers.
4. Run lint periodically.
5. Run audit whenever new feedback accumulates.

wiki/index.md format

The LLM rebuilds index.md on every compile and touches it on every ingest. Format:

markdownCopy code
# Index — <Topic>

> One-sentence scope of the wiki.

## 🔖 Navigation
- [[#Concepts]] · [[#Entities]] · [[#Summaries]] · [[#Open Questions]]

## Concepts
### <Category A>
- [[concepts/Foo]] — one-line summary
- [[concepts/Bar/index|Bar]] — (folder-split) one-line summary
    - [[concepts/Bar/aspect-1]] — ...
    - [[concepts/Bar/aspect-2]] — ...

### <Category B>
- ...

## Entities
- [[entities/Andrej Karpathy]] — AI researcher, author of the llm-wiki pattern

## Summaries (chronological)
- 2026-04-09 — [[summaries/llm-wiki-gist]] — Karpathy's original Gist

## Open Questions
- Q1: ...

Rules:

• Every wiki page must appear exactly once in index.md. lint enforces this.
• Folder-split concepts show hierarchy via indented bullets.
• index.md + CLAUDE.md together are what the AI reads at session start.

log/ format

See references/log-guide.md for full details. Minimum:

• One file per day: log/YYYYMMDD.md
• H1 = the date; H2 per entry with ## [HH:MM] <op> | <one-line description>
• Ops: compile, ingest, query, lint, audit, promote, split, scaffold

Quick grep across history: grep -rh "^## \[" log/ | tail -20.

Use cases

• Research deep-dive — reading papers/articles on a topic over weeks; the wiki evolves with your understanding, and the audit trail keeps AI mistakes from silently accumulating
• Personal wiki — journal entries, notes, ideas compiled into a personal encyclopedia; comment on anything you disagree with later, the AI corrects it
• Team knowledge base — fed by Slack threads, meeting notes, docs; team members file corrections through the web viewer
• Reading companion — filing each book chapter as you go; builds a rich companion wiki by the end
