Sitemap Verification Skill

Purpose

Validate the dynamic sitemap generation for the PM Philosophy Map, ensuring all 303 episodes and static pages are properly indexed with correct URLs and metadata.

When to Use This Skill

• User asks to "verify sitemap"
• User wants to "check sitemap URLs"
• User requests to "validate sitemap.xml"
• User asks to "audit sitemap generation"
• Before production deployments or after adding new episodes

Context

• Sitemap file: app/sitemap.ts
• Dynamic generation: Next.js MetadataRoute.Sitemap
• Expected entries: 306 total (3 static pages + 303 episodes)
• Domain: https://lenny.productbuilder.net

What to Check

1. Sitemap Configuration

File: app/sitemap.ts

Validate:

• ✅ Uses correct baseUrl (process.env.NEXT_PUBLIC_BASE_URL || 'https://lenny.productbuilder.net')
• ✅ No localhost fallback
• ✅ Imports allEpisodes correctly
• ✅ Generates MetadataRoute.Sitemap type

2. Static Pages

Expected entries:

[
  { url: '/', priority: 1, changeFrequency: 'weekly' },
  { url: '/quiz', priority: 0.9, changeFrequency: 'weekly' },
  { url: '/explore', priority: 0.8, changeFrequency: 'daily' }
]

Validate:

• ✅ All static pages included
• ✅ Correct priority values (1.0 for home is highest)
• ✅ Appropriate changeFrequency
• ✅ lastModified dates present

3. Episode Pages

Expected: 303 episode URLs

Validate:

• ✅ All episodes from allEpisodes.ts included
• ✅ URL format: {baseUrl}/episodes/{slug}
• ✅ No duplicate slugs
• ✅ Valid slugs (no spaces, special chars)
• ✅ lastModified uses episode.publishDate or fallback to new Date()
• ✅ Appropriate priority (0.6 for episodes)
• ✅ changeFrequency set to 'monthly'

4. URL Validation

Check for issues:

• ❌ localhost URLs (http://localhost:3000)
• ❌ Malformed URLs (missing protocol, trailing slashes inconsistency)
• ❌ 404s (episodes that don't have pages)
• ❌ Redirects (old slugs, renamed episodes)
• ❌ Duplicate URLs

5. XML Output

After build, validate:

• ✅ Valid XML structure
• ✅ Proper <urlset> namespace
• ✅ All <url> entries have <loc>, <lastmod>, <changefreq>, <priority>
• ✅ Dates in ISO 8601 format (YYYY-MM-DD)
• ✅ Proper escaping of special characters

Verification Process

Step 1: Read Sitemap Source

# Read the sitemap generator
Read app/sitemap.ts
# Check for localhost references
Grep "localhost" in app/sitemap.ts

Step 2: Validate Episode Count

# Count episodes in allEpisodes
Read lib/allEpisodes.ts
# Verify count matches 303 episodes

Step 3: Build and Generate Sitemap

# Build the app to generate sitemap
npm run build
# Access sitemap (dev or production)
curl http://localhost:3000/sitemap.xml
# Or check .next/server/app/sitemap.xml

Step 4: Validate XML Structure

# Check XML is valid
xmllint --noout sitemap.xml 2>&1 || echo "Valid XML"
# Count URL entries
grep -c "<loc>" sitemap.xml
# Should be 306 (3 static + 303 episodes)

Step 5: Check for Issues

# Find localhost URLs
grep "localhost" sitemap.xml
# Find duplicate URLs
grep "<loc>" sitemap.xml | sort | uniq -d
# Check for malformed URLs
grep -E "<loc>.*[^/]</loc>" sitemap.xml

Quick Commands

Generate and view sitemap:

npm run build && curl http://localhost:3000/sitemap.xml | head -50

Count sitemap entries:

grep -c "<url>" sitemap.xml
# Expected: 306

Find localhost references:

grep -i "localhost" app/sitemap.ts

Validate all episode pages exist:

# Check if all episodes have transcript files
ls episodes/*/transcript.md | wc -l
# Should be 303

Sample Output Format

Healthy Sitemap Entry:

<url>
  <loc>https://lenny.productbuilder.net/episodes/brian-chesky</loc>
  <lastmod>2024-01-15T00:00:00.000Z</lastmod>
  <changefreq>monthly</changefreq>
  <priority>0.6</priority>
</url>

Issue - Localhost URL:

<url>
  <loc>http://localhost:3000/episodes/brian-chesky</loc> <!-- ❌ BAD -->
  ...
</url>
