X Feed Summarizer

X/Twitter Feed Summarizer

Fast extraction and summarization of X feed content using agent-browser CDP connected to your existing logged-in Chrome session via CDP on port 9222.

IMPORTANT: Always use --cdp 9222 to connect to your logged-in Chrome. Never use --auto-connect or a fresh browser — you won't be logged in.

Prerequisites

Requires chrome-browser skill to be running first. Verify:

curl -s --max-time 3 http://localhost:9222/json/version

Quick Workflow

Step 1: Navigate

agent-browser --cdp 9222 open https://x.com/home
agent-browser --cdp 9222 wait 5000

Do NOT use --load networkidle — X never reaches networkidle. Use fixed wait 5000.

Step 2: Click Following tab

agent-browser --cdp 9222 snapshot -i
# Find "Following" tab ref from snapshot, e.g. e12
agent-browser --cdp 9222 click e12
agent-browser --cdp 9222 wait 3000

Step 3: Extract posts with links (gets ~12 posts)

agent-browser --cdp 9222 eval --stdin <<'EVALEOF'
JSON.stringify(
  Array.from(document.querySelectorAll('article[data-testid="tweet"]')).slice(0, 12).map((a, i) => {
    const userEl = a.querySelector('[data-testid="User-Name"]');
    const textEl = a.querySelector('[data-testid="tweetText"]');
    const timeEl = a.querySelector('time');
    const linkEl = timeEl ? timeEl.closest('a') : null;
    const links = Array.from(a.querySelectorAll('a[href]'))
      .map(l => ({ text: l.innerText.trim().slice(0, 50), href: l.href }))
      .filter(l => l.text && l.href.includes('x.com'));
    return {
      i,
      user: userEl ? userEl.innerText.replace(/\n/g, ' ') : 'Unknown',
      text: textEl ? textEl.innerText.slice(0, 400) : '',
      time: timeEl ? timeEl.getAttribute('datetime') : '',
      link: linkEl ? 'https://x.com' + linkEl.getAttribute('href') : '',
      links
    };
  }).filter(p => p.text),
  null, 2
)
EVALEOF

Step 4: Scroll and extract more (repeat 1-2x for 20+ posts)

agent-browser --cdp 9222 scroll down 2000
agent-browser --cdp 9222 wait 1500
# repeat eval from Step 3 — adjust .slice(0, 20) to get more

Speed Optimizations

1. Use scroll down 2000 for fast scrolling
2. Batch extractions — grab 12-20 posts per eval call
3. Skip screenshots — pure text + links extraction is faster
4. Use 1500ms wait after scrolling — enough for tweet loading
5. Use JS eval with data-testid — more reliable than snapshot text parsing

Summary Format

Output the summary as readable text:

## X Feed Summary

### Main Themes
- Theme 1: description

### Key Highlights
1. **[Post text snippet](https://x.com/user/status/123)** - @user: summary
2. ...

### Viral Content
- High engagement post: [link](url)

### Notable Accounts
- [@handle](https://x.com/handle): active on topics

Keep it conversational, scannable, with all links as Markdown text.

X DOM Selectors Reference

• Tweet article: article[data-testid="tweet"]
• Tweet text: [data-testid="tweetText"]
• User name block: [data-testid="User-Name"]
• Timestamp (with href to tweet): time inside an <a> tag
