Routing front door for obsidian-second-brain — a self-rewriting Obsidian vault that evolves Karpathy's LLM-Wiki pattern. Every source REWRITES existing pages instead of appending: people updated, claims revised, contradictions reconciled, patterns synthesized automatically. 45 commands across 4 layers, background + 4 scheduled agents, 4 role presets, AI-first write validator. Cross-CLI: Claude Code, Codex CLI, Gemini CLI, OpenCode.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# obsidian-second-brain A routing-first front door for [**obsidian-second-brain**](https://github.com/akillness/obsidian-second-brain) — an evolution of [Karpathy's LLM-Wiki pattern](https://gist.github.com/karpathy/442a6bf555914893e9891c11519de94f) into **a vault that rewrites itself**. Where the LLM-Wiki appends new pages, this skill REWRITES existing ones: people get updated, claims revised, stale facts replaced, contradictions reconciled automatically, and cross-source patterns synthesized on their own — while you sleep. > **Keyword**: `obsidian second brain` · `self-rewriting vault` · `obsidian-save` · `obsidian-ingest` > > One codebase, four CLIs (Claude Code · Codex CLI · Gemini CLI · OpenCode), same brain. ## When to use this skill - The user wants an Obsidian vault that **maintains itself** instead of a static filing cabinet. - The user wants to **capture work into the vault**: save a conversation, ingest a URL / PDF / audio / screenshot, log a session, create daily notes, track tasks/people/decisions. - The user wants the vault to **reconcile contradictions** and **synthesize cross-source patterns** automatically. …

How to install
mdr add akillness/jeo-skills/obsidian-second-brain@sha256:ff9d3247bdb36163The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
