Code Changes Verified

1. YouTube Content Display Fix

File: scripts/run-brief.js

Before:

// Default handler - only showed preview field
if (item.url) {
  html += `<a href="${item.url}">${item.title}</a>`;
}
if (item.preview) html += `<div class="meta">${item.preview}</div>`;

After:

// Dedicated YouTube handler
} else if (section.type === 'youtube') {
  html += `<strong>${item.title}</strong>`;
  if (item.aiSummary) {
    html += `<div style="...">📝 Summary: ${item.aiSummary}</div>`;
  } else if (item.description) {
    html += `<div class="meta">${item.description}</div>`;
  }
  if (item.url) {
    html += `<div class="meta">→ <a href="${item.url}">Watch video</a></div>`;
  }
}

Status: ✅ VERIFIED

---

2. AI Summarization Integration

File: scripts/run-brief.js

Added:

const { summarizeSections } = require('../lib/summarizer');

// ... later in runBrief()
let enhancedSections = sections;
if (brief.aiSummary?.enabled !== false) {
  console.log('\n🤖 Running AI summarization...');
  try {
    enhancedSections = await summarizeSections(sections, {
      style: brief.aiSummary?.style || 'concise',
      maxItemsPerSource: brief.aiSummary?.maxItemsPerSource || 5,
      prioritize: brief.aiSummary?.prioritize || 'relevance',
      userContext: brief.aiSummary?.userContext
    });
  } catch (err) {
    console.warn('⚠️ AI summarization failed:', err.message);
    enhancedSections = sections; // Fallback
  }
}

Status: ✅ VERIFIED

---

3. Enhanced Email Template

File: scripts/run-brief.js

Added for all content types:

// AI Summary (highlighted)
if (item.aiSummary) {
  html += `<div style="margin-top: 8px; padding: 10px; background: #f0f8ff; border-left: 3px solid #007bff; border-radius: 4px;">`;
  html += `<strong style="color: #007bff;">📝 Summary:</strong> ${item.aiSummary}`;
  html += `</div>`;
}

Status: ✅ VERIFIED
