Browser Bookmarks

Analyze and clean up browser bookmark exports.

Capabilities

• Duplicate Detection: Find duplicate URLs across folders
• Dead Link Check: HTTP HEAD requests to detect broken links
• Organization: Categorize and suggest folder restructuring
• Export Parsing: Chrome/Firefox HTML and JSON bookmark formats

Instructions

1. Parse bookmarks: Extract URLs, titles, folders from HTML/JSON export

   # Extract URLs from Chrome HTML export
   grep -oP 'HREF="\K[^"]+' bookmarks.html | sort > urls.txt
   wc -l urls.txt  # total bookmarks
   

2. Find duplicates:

   sort urls.txt | uniq -d  # duplicate URLs
   sort urls.txt | uniq -c | sort -rn | head -20  # most duplicated
   

3. Check dead links (batch with rate limiting):

   while read url; do
     code=$(curl -s -o /dev/null -w "%{http_code}" -m 5 -L "$url" 2>/dev/null)
     [ "$code" != "200" ] && echo "$code $url"
     sleep 0.5  # rate limit
   done < urls.txt
   

4. Report format:

   📚 Bookmark Analysis — <filename>
   Total: 342 | Duplicates: 18 | Dead: 7
   
   ## Duplicates
   | URL | Count | Folders |
   |-----|-------|---------|
   
   ## Dead Links (non-200)
   | URL | Status | Title |
   |-----|--------|-------|
   

Edge Cases

• Large exports (>5000 bookmarks): Sample dead link checks; full duplicate scan is fine
• Paywalled sites: May return 403 — flag as "possibly paywalled" not "dead"
• Redirects: Follow redirects (curl -L); flag permanent redirects (301) for URL updates

Security

• Bookmark files may contain private/internal URLs — don't share results publicly
• Rate-limit external requests to avoid IP blocks

Requirements

• Exported bookmarks file (Chrome: chrome://bookmarks → Export, Firefox: Library → Export)
• curl, grep, sort (standard Unix tools)
• No API keys needed
