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

# COG: Agentic Second Brain - Universal Agent Commands

This document defines the available commands/skills for AI agents interacting with COG (Cognition + Obsidian + Git) - a self-evolving agentic second brain system.

**Compatible with:** OpenAI agents, Claude (via this file), and any AI that reads markdown.

> **Note:** Claude Code users should use `.claude/skills/` and Kiro users should use `.kiro/powers/` for native support. This file serves as universal documentation for all other agents.

## Available Commands

### /onboarding

**Description:** Personalize COG for your workflow - creates profile, interests, and watchlist files with a smart, conversational setup.

**Triggers:**
- `/onboarding`
- "onboarding"
- "setup COG"
- "setup my profile"
- "get started"

**Purpose:** Welcome new users and collect essential information to personalize their COG experience through natural conversation - not sequential form-filling. Creates profile documents stored as markdown files within the vault.

**How it works:**
1. Asks ONE open-ended question: "Tell me about yourself - name, role, and what you're interested in"

How to install

The exact contents, by fingerprint

mdr add huytieu/cog-second-brain/AGENTS.md@sha256:23b7848485f777bb

The line at the top of this page pins the label git:20261023.65f43f1, 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.
