Key Insights

**Insight 1: Markdown is the native interface for AI Agents**

Manus ($2B acquisition), OpenClaw (355K+ stars), and Claude Code all chose Markdown files -- not vector databases -- for AI memory. Obsidian vault = a bunch of Markdown files.

**Insight 2: LLMs should be "compilers", not "retrievers"**

Karpathy's core argument: instead of building RAG to retrieve your notes, let the LLM directly maintain your knowledge base. Validated at 400K+ characters scale.

**Insight 3: CLAUDE.md + index.md does 80% of the work**

No complex MCP setup needed. One CLAUDE.md + one index.md per folder is enough for Claude Code to efficiently navigate your entire knowledge base.
