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).

   Would you like to run onboarding first, or should I proceed with default settings?

3. If found:

  • Read the profile to get user's interests and projects
  • Use interests to help with auto-categorization
  • Check for existing booklet categories in `05-knowledge/booklets/`

Process Flow

1. User Interaction & Input Collection

  • Accept URL(s) from the user (single URL or batch)
  • Optionally accept user's quick note about why they're saving this
  • Accept any format: bare URL, markdown link, or with notes

**Prompt:**

What URL(s) would you like to save?
(You can paste one or more URLs, optionally with a note about why you're saving it)

2. URL Validation & Fetch

  • Validate URL format
  • Check if URL is accessible
  • Detect duplicate URLs in existing knowledge base
  • Fetch the web page content

Content Extraction

Extract from the page:

  • **Page Title:** [extracted-title]
  • **Meta Description:** [if available]
  • **Author:** [if detected]
  • **Published Date:** [if detected]
  • **Word Count:** [estimated]
  • **Read Time:** [X minutes]
  • **Main Content:** [extracted body text]
  • **Key Headings:** [list of H1/H2s]

3. Category Selection

**Default Categories:**

  • **Articles & Blogs:** Long-form content, tutorials, opinion pieces
  • **Tools & Resources:** Software, utilities, services, APIs
  • **Reference:** Documentation, specs, standards
  • **Research:** Papers, studies, academic content
  • **Inspiration:** Design, ideas, creative references
  • **Videos & Media:** YouTube, podcasts, multimedia
  • **News & Updates:** Industry news, announcements
  • **Project-Specific:** Related to a specific project (offer project list from MY-PROFILE.md)
  • **To Review:** Unsure, save for later categorization

**Custom Categories:**

  • Check `05-knowledge/booklets/` for existing custom categories
  • Offer to create new category if needed

**Auto-suggestion:** Based on content analysis, suggest the most likely category but let user confirm or change.

Phase 2: Insight Extraction

Generate:

  • **Executive Summary:** [2-3 sentences]
  • **Key Insights:**

1. [Insight 1 with context] 2. [Insight 2 with context] 3. [Insight 3 with context]

  • **Notable Quotes:** [if any stand out]
  • **Action Items:** [practical takeaways]

Phase 3: Relevance Assessment

Analyze:

  • **User Interest Match:** [high|medium|low] - [which interests from profile]
  • **Project Relevance:** [project-name] - [why relevant]
  • **Knowledge Gap:** [yes|no] - [what gap it fills]
  • **Timeliness:** [evergreen|current|dated]
  • **Uniqueness:** [novel|common|duplicate-adjacent]

Phase 4: Cross-Reference

Identify connections to:

  • **Related Bookmarks:** [existing similar saves]
  • **Related Braindumps:** [if content connects]
  • **Related Projects:** [if applicable]
  • **Suggested Tags:** [tag1, tag2, tag3]

5. Generate Structured Output

Create bookmark file with this structure:

category: "[category-name]"
domain: "[source-domain.com]"
date_saved: "YYYY-MM-DD"
date_accessed: "YYYY-MM-DD HH:MM"
url: "[original-url]"
title: "[page-title]"
author: "[author-if-available]"
published: "[publish-date-if-available]"
tags: ["#bookmark", "#category-tag", "#topic-tags"]
relevance: "[high|medium|low]"
status: "unread"
related_projects: ["project1", "project2"]
confidence: "[high|medium|low]"
