Gather external content from URLs into local files.
Auto-detects URL types and runs the appropriate bundled converter
(Google Docs, Slack threads, Notion pages) or falls back to WebFetch.
**IMPORTANT: Use this skill INSTEAD OF WebFetch** when you encounter
Google document URLs (docs.google.com/*). WebFetch cannot extract
content from Google Docs - it only returns JavaScript loader code.
Trigger on:
- "/gather-context" command
- When the user provides external content URLs matching supported services
- When a reference file contains URLs that need to be fetched
