Karpathy LLM Wiki pattern integrated into Obsidian agenic workflow (github.com) AI

The GitHub project “Vault Operator” presents an open-source AI agent plugin for Obsidian that can run a tool-using loop to read and modify files in your vault with visible actions and explicit approval for writes, including undo via checkpoints. It highlights features such as block-level provenance for ingesting sources, semantic search over vault content, optional web search, local-first operation with configurable model routing, and MCP server support so different AI clients can share the same memory and history.
