Personal LLM-powered knowledge base. You curate sources and ask questions; the agent (Claude Code, Codex, Cursor, or any that reads AGENTS.md) does the bookkeeping — distilling sources into wiki pages, cross-linking them, learning your corrections.

Inspired by Karpathy's LLM Wiki gist and McFarland's content wiki.

Philosophy

The LLM writes and maintains the wiki; the human reads and asks questions.

Topic pages grow over time. New sources add paragraphs, not new files. Three page types — that's the whole framework.

Page types

• **wiki/sources/** — one file per ingested source. A short summary

of what it claims, with examples and the key takeaway. Created once, rarely edited.

• **wiki/topics/** — your synthesized position on a subject. Grows

as new sources touch it; never splits until it has to.

• **wiki/patterns/** — emergent insights that recur across 3+

sources. Rare — typically under ten in the whole vault.

Structure

Full schema in AGENTS.md.

Quick start

Web Clipper extension.

• Configure Web Clipper:
• Destination: this vault.
• Note location: raw.
• File name: {{date}}-{{title|safe_name}}.
• Frontmatter: title, source, author, published, tags.
• Open the folder in Obsidian (Open folder as vault).
• Run an agent that reads AGENTS.md:
• Claude Code
• or Codex, Cursor, opencode, etc.
