Quick capture URLs with automatic content extraction, insights, and categorization into knowledge booklets.

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 URL Dump Skill

## Purpose
Transform raw URLs into structured, insightful knowledge entries through intelligent content extraction, categorization, and integration with the user's knowledge base. Quick capture with automatic insight generation.

## When to Invoke
- User shares a URL they want to save
- User says "save this link", "bookmark this", "url dump", or "save for later"
- User pastes a URL and wants to capture it
- User wants to organize web resources into their knowledge base

## Agent Mode Awareness

**Check `agent_mode` in `00-inbox/MY-PROFILE.md` frontmatter:**
- If `agent_mode: team` — delegate content extraction, analysis, and categorization to a sub-agent while handling user interaction directly. The sub-agent fetches URL content, generates insights, and returns structured results for filing.
- If `agent_mode: solo` (default) — handle everything directly in the conversation. No delegation.

## Pre-Flight Check

**Before executing, check for user profile:**

1. Look for `00-inbox/MY-PROFILE.md` in the vault
2. If NOT found:
   ```
   Welcome to COG! It looks like this is your first time.

   Before we start, let's quickly set up your profile (takes 2 minutes).

How to install

The exact contents, by fingerprint

mdr add huytieu/cog-second-brain/url-dump@sha256:de6f44da9b2bf0f4

The line at the top of this page pins the label git:20260622.5e9851c, 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.
