What it does
Karpathy LLM Wiki is an agent skill from LearnPrompt/andrej-karpathy-skills. Build and maintain an LLM-powered personal knowledge base or wiki. Use this skill when the user wants to organize research notes, build a second brain, set up an Obsidian vault with LLM compilation, ingest papers or articles automatically, or mentions "personal knowledge base", "LLM wiki", "second brain", "knowledge management", "ingest papers", "obsidian + LLM". Based on Karpathy Gist and 59k-like post.
Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Knowledge Management, covering LLM wikis and Second brain. It works with Obsidian. The repository describes itself as: Karpathy-inspired Agent Skills collection. The licence is MIT.
When your agent uses it
- The user wants to organize research notes
- Build a second brain
- Set up an Obsidian vault with LLM compilation
- Articles automatically
Example prompts
- “personal knowledge base”
- “LLM wiki”
- “second brain”
- “/karpathy-llm-wiki”
Workflow steps
5 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 9e46dec. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
x.comgist.github.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Karpathy LLM Wiki loads about 1.4k tokens when it runs. Until then it costs about 106 tokens; SKILL.md has 189 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Skill 2: LLM Wiki / Personal Knowledge Base（LLM知识库）

Core Principle
You explore. The LLM maintains.
You read the world, capture raw signals. The LLM compiles, cross-links, deduplicates, lint-checks, and surfaces contradictions. Your Obsidian vault is the output, not the input.

1. Ingest Prompt
You are a knowledge compiler. Given this raw source:
[PASTE RAW CONTENT]
Source URL/title: [SOURCE]
Date: [DATE]
Extract and output:
1. Key entities (people, concepts, tools, papers) — one per line with a 2-sentence description
2. Key claims with confidence level (high/medium/speculative)
3. Connections to existing topics: [LIST YOUR KNOWN TOPICS]
4. Contradictions with anything you know: [WHAT YOU ALREADY BELIEVE]
5. Suggested entity page updates (format: ENTITY_NAME | UPDATE_TEXT)2. Compile Wiki Entry Prompt
You are maintaining a personal knowledge wiki. Update the entity page for [ENTITY_NAME].
Existing page content:
[CURRENT_PAGE_CONTENT]
New information to integrate:
[NEW_INFO]
Rules:
- Preserve all existing information; only add or correct
- Flag contradictions with: ⚠️ CONFLICT: [old claim] vs [new claim]
- Keep the page under 500 words
- End with: "Last updated: [DATE] | Sources: [LINKS]"3. Weekly Ingest Prompt (run every week)
Process this week's reading list:
[PASTE 5-10 ITEMS: title + URL + 1-sentence summary]
For each item:
1. Extract top 3 entities to update
2. List 2-3 key claims worth adding to wiki
3. Note any contradictions with existing knowledge
4. Suggest connections to other entities in my wiki
Output as structured markdown, one section per item.4. Lint / Contradiction Check Prompt
Review these wiki entries for consistency:
[PASTE 3-5 RELATED ENTITY PAGES]
Find and report:
1. Factual contradictions between pages
2. Duplicate information that should be merged
3. Outdated claims that should be flagged
4. Missing cross-links between related entities
Format: ISSUE | PAGE | LINE | SUGGESTED FIX5. Query Prompt
Search my personal knowledge wiki to answer this question:
Question: [QUESTION]
Wiki context:
[PASTE RELEVANT PAGES]
Answer with:
1. Direct answer (2-3 sentences)
2. Supporting evidence from wiki (with page citations)
3. Gaps: what I don't know yet
4. Suggested reading to fill gapsMemory / Context Hygiene (Anti-Pollution Rules)
Karpathy noted LLM memory "trying too hard" — a question from 2 months ago poisons every future conversation. Prevent this:
- Never rely on LLM built-in memory for knowledge — use your wiki instead
- Start fresh sessions for new topics; don't let old context bleed in
- Explicit resets: If continuing a long session, open with "Ignore all prior context about X"
- Version your wiki: Commit wiki changes with git so you can diff what changed
