AI Second Brain Skills Your folder becomes your app. No database. No embeddings. Just markdown — and an AI that knows where to look. Two Claude Code skills that turn any folder into a compounding, AI-maintained knowledge base. Based on Andrej Karpathy's LLM wiki pattern, with a research loop inspired by his autoresearch project. TL;DR Then in Claude Code: Drop a source into once a week That's the whole loop. Why this exists Most people's AI workflow: paste context into a chat, get an answer, start a new chat, paste everything again. Knowledge evaporates between sessions. Nothing compounds. The wiki pattern is different. The LLM reads every source once, extracts the knowledge, and writes it into an interlinked set of markdown files — a persistent wiki that sits between you and your raw sources. When you ask a question, it reads the wiki (not the sources). When you add a source, it integrates, flags contradictions, and strengthens the synthesis. Knowledge is

Grades come from a rule-based scan built on the SlowMist agent-security taxonomy, covering 11 red-flag categories including credential harvesting, data exfiltration, and curl | sh installers. It is a first-layer scan, not a manual audit — we say so rather than overstate it.
The scale of the problem is documented independently: Liu et al. (2026), in a study of 31,132 agent skills, report that 26.1% contain security vulnerabilities. Our own full-catalog census is published as a citable open dataset.
