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:

Look for 00-inbox/MY-PROFILE.md in the vault

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?

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
