Operate Obsidian vaults as self-rewriting knowledge bases with AI-powered research and automatic reconciliation.

description: >
Operate any Obsidian vault as a living, self-rewriting second brain (an evolution
of Karpathy's LLM Wiki pattern: sources rewrite existing pages, contradictions
reconcile automatically, scheduled agents maintain the vault while you sleep).
Use this skill whenever
the user asks Claude to read, write, update, search, or manage their Obsidian
vault - including saving notes from conversation, creating daily entries, updating
kanban boards, logging dev work, managing people notes, capturing decisions,
tracking deals, or maintaining any vault structure. Also triggers when the user
wants to bootstrap a new vault from scratch, run a vault health check, or drop
a _CLAUDE.md into their vault so all Claude surfaces share the same operating rules.
Includes a research toolkit (7 commands: /x-read, /x-pulse, /research, /research-deep,
/notebooklm, /youtube, /podcast) for AI-powered research via Grok, Perplexity, NotebookLM,
YouTube, and podcast feeds - findings save
to the vault automatically following the AI-first vault rule. Use proactively whenever
the conversation produces information worth preserving (decisions, people met, projects
started, tasks completed, lessons learned, research findings).
