LLM Wiki

Pattern originally described by Andrej Karpathy: LLM Wiki

The LLM Wiki is a structured knowledge base that lives alongside — but is separate from — the conversation memory system. It uses Obsidian-style markdown (wikilinks, callouts, frontmatter) and is organized according to a schema.md the agent reads before every operation.

How it works

• The vault root is /mnt/notebook (sandbox) or ${MOUNT_NOTEBOOK} (host).
• Three agent-maintained navigation files live at the vault root:
  • schema.md — vault conventions, folder layout, and page types. The agent reads this first on every operation.
  • index.md — catalog of synthesized pages, updated on every ingest or query filing.
  • log.md — append-only chronological record of all agent operations.
• The agent reads and writes vault pages directly via ReadFileTool/WriteFileTool/EditFileTool.
• WikiManager bootstraps these three files on first init (from skills/notebook/schema_example.md), then stays out of the way.

Distinction from conversation memory

	Conversation Memory	LLM Wiki
Content	Episodic facts extracted from chats	Synthesized knowledge pages
Structure	Daily logs + MEMORY.md + LanceDB	Obsidian vault (schema-defined folders)
Written by	Automatic extraction	Agent directly via file tools
Searched via	LanceDB hybrid search	GlobTool + GrepTool + wikilinks
Lifetime	Accumulates across conversations	Persistent; updated by agent on ingest

Operational skills

The notebook skill (under skills/notebook/) provides the agent with procedures for working with the vault:

• ingest.md — procedure for ingesting new content into the vault
• lint.md — procedure for auditing and cleaning vault pages
