Blog Post Editor for MyImageUpscaler

Edit existing blog posts to improve quality, SEO, or fix issues.

Quick Reference

Authentication: Use x-api-key header with BLOG_API_KEY from .env.api

Changelog

Before starting: Read recent entries and SEO backlogs to understand what has already been done.

tail -60 .Codex/skills/blog-changelog.md
sed -n '1,140p' docs/SEO/maintenance/seo-changes-backlog.md
sed -n '1,120p' docs/SEO/maintenance/gsc-request-indexing-backlog.md

If the target post was recently refreshed, redirected, unpublished, queued for indexing, or is waiting for GSC data lag, do not rewrite it again unless the user explicitly asks or blog-performance-monitor has produced an edit-now escalation with its action threshold met. Treat non-escalated recent-refresh tasks as validation-only or request-indexing follow-up.

After finishing: Append a brief entry.

cat >> .Codex/skills/blog-changelog.md << 'EOF'

## YYYY-MM-DD

### [Type]: [Short title]
**Affected:** [slug(s)]
**Why:** [reasoning]
**Changes:**
- `slug` — what was done

Workflow

1. CHANGELOG → Read recent blog changelog and SEO maintenance backlogs first
2. FETCH     → GET /api/blog/posts/[slug]
3. ANALYZE   → Review current content/SEO
4. IMPROVE   → Generate new content/image if needed
5. UPDATE    → PATCH /api/blog/posts/[slug]
6. VERIFY    → Check changes applied
7. CHANGELOG → Append entry with what changed and why

Step 1: Fetch & Analyze Post

# Load environment
source scripts/load-env.sh
API_KEY=$(grep BLOG_API_KEY .env.api | cut -d'=' -f2)

# Get post with full details
curl -s http://localhost:3000/api/blog/posts/how-to-upscale-images \
  -H "x-api-key: $API_KEY" | jq '{
  title,
  description,
  status,
  titleLength: (.title | length),
  descriptionLength: (.description | length),
  category,
  tags
}'

Step 2: Update Post

All fields are optional. Only include what you want to change.

# Update specific fields
curl -s -X PATCH http://localhost:3000/api/blog/posts/how-to-upscale-images \
  -H "x-api-key: $API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "title": "How to Upscale Images 4x: Complete Guide [2026]",
    "description": "Upscale images 4x quality instantly with AI. Free tool for photos, graphics, artwork. No quality loss."
  }' | jq '{title, updated_at}'

Updatable Fields

Step 3: Update Featured Image

Generate with AI (Recommended)

Use the AI image generation skill for unique, contextual images:

# Generate a blog-optimized featured image (1200x630)
yarn tsx .Codex/skills/ai-image-generation/scripts/generate-ai-image.ts \
  "Modern laptop showing AI image upscaling interface, before and after comparison, professional setup, blue lighting, photorealistic" \
  ./new-featured.png \
  1200 630

# Upload to Supabase Storage
UPLOAD=$(curl -s -X POST http://localhost:3000/api/blog/images/upload \
  -H "x-api-key: $API_KEY" \
  -F "file=@./new-featured.png" \
  -F "alt_text=AI image upscaling before and after comparison")

IMAGE_URL=$(echo "$UPLOAD" | jq -r '.data.url')

# Update post with new URL
curl -s -X PATCH http://localhost:3000/api/blog/posts/[slug] \
  -H "x-api-key: $API_KEY" \
  -H "Content-Type: application/json" \
  -d "{\"featured_image_url\": \"$IMAGE_URL\", \"featured_image_alt\": \"AI image upscaling before and after comparison\"}"

See /ai-image-generation skill for prompt templates and best practices.

Upload Local Image

Images are automatically compressed to WebP format (max 1920x1080, 80% quality) before storage.

# Upload (auto-converts to WebP)
UPLOAD=$(curl -s -X POST http://localhost:3000/api/blog/images/upload \
  -H "x-api-key: $API_KEY" \
  -F "file=@./new-featured.jpg" \
  -F "alt_text=New featured image")

IMAGE_URL=$(echo "$UPLOAD" | jq -r '.data.url')

# Update post with new URL
curl -s -X PATCH http://localhost:3000/api/blog/posts/[slug] \
  -H "x-api-key: $API_KEY" \
  -H "Content-Type: application/json" \
  -d "{\"featured_image_url\": \"$IMAGE_URL\"}"

Storage details:

• Format: WebP (auto-converted)
• Max dimensions: 1920x1080
• Compression: 80% quality
• Cache: 1 year CDN cache

Step 4: Add/Update Inline Images

Posts should have 2-3 inline images in the markdown content. To add or update them:

# Generate new inline images
yarn tsx .Codex/skills/ai-image-generation/scripts/generate-ai-image.ts \
  "Split screen: pixelated photo left, sharp enhanced photo right, dramatic comparison" \
  ./new-inline.png 800 600

# Upload to storage
INLINE_URL=$(curl -s -X POST http://localhost:3000/api/blog/images/upload \
  -H "x-api-key: $API_KEY" \
  -F "file=@./new-inline.png" \
  -F "alt_text=Before and after comparison" | jq -r '.data.url')

echo "Use this in content: ![Before and after comparison]($INLINE_URL)"

Then update the content with the new image markdown (see Step 5).

Step 5: Update Content

For large content updates, write to file first. Include inline images in markdown:

cat > /tmp/content-update.json << 'EOF'
{
  "content": "# Updated H1 Title\n\nNew intro with primary keyword...\n\n## Section 1\n\nImproved content with more details...\n\n![Inline image 1 description](https://your-supabase-url/inline-1.webp)\n\n## Section 2\n\nMore comprehensive content...\n\n![Inline image 2 description](https://your-supabase-url/inline-2.webp)\n\n## Conclusion\n\nSummary and [CTA](https://myimageupscaler.com)."
}
EOF

curl -s -X PATCH http://localhost:3000/api/blog/posts/[slug] \
  -H "x-api-key: $API_KEY" \
  -H "Content-Type: application/json" \
  -d @/tmp/content-update.json | jq '{title, updated_at}'

Inline Image Rules:

• Place 2-3 images evenly throughout content
• Place after the section they illustrate
• Use descriptive alt text for SEO

Humanizing Content

AI Patterns to AVOID

Human Writing Techniques

❌ AI: "Image upscaling represents a significant advancement in AI technology."
✅ Human: "I've tested dozens of upscalers. Most make your photos look like plastic."

❌ AI: "This solution offers numerous benefits."
✅ Human: "Here's what makes this different: it actually preserves details."

❌ AI: "The process facilitates enhanced quality."
✅ Human: "Your photos get sharper. Period."

Writing Rules:

• First sentence delivers value immediately
• Use active voice
• Keep paragraphs short (2-4 sentences)
• Mix sentence lengths
• Use first-person occasionally

Verify Changes

# API check
curl -s http://localhost:3000/api/blog/posts/[slug] \
  -H "x-api-key: $API_KEY" | jq '{title, updated_at, status}'

# Frontend check
curl -s -o /dev/null -w "%{http_code}" http://localhost:3000/blog/[slug]

Common Operations

List All Posts

curl -s "http://localhost:3000/api/blog/posts?status=published&limit=50" \
  -H "x-api-key: $API_KEY" | jq '.data[] | {slug, title, status}'

Bulk Update Categories

# Get all posts with old category
curl -s "http://localhost:3000/api/blog/posts?category=OldCategory" \
  -H "x-api-key: $API_KEY" | jq '.data[].slug' | while read slug; do
  # Update each post
  curl -s -X PATCH "http://localhost:3000/api/blog/posts/$slug" \
    -H "x-api-key: $API_KEY" \
    -H "Content-Type: application/json" \
    -d '{"category": "NewCategory"}'
done

Republish Post (triggers updated_at)

# Unpublish first
curl -s -X POST http://localhost:3000/api/blog/posts/[slug]/unpublish \
  -H "x-api-key: $API_KEY"

# Then publish
curl -s -X POST http://localhost:3000/api/blog/posts/[slug]/publish \
  -H "x-api-key: $API_KEY"

Environment Configuration

# Load environment
source scripts/load-env.sh
API_KEY=$(grep BLOG_API_KEY .env.api | cut -d'=' -f2)

Troubleshooting

Post not found (404)

• Check slug is correct (lowercase, hyphens only)
• For unpublished posts, use API endpoint not frontend URL

Update not applying

• Check updated_at timestamp changed
• Verify JSON is valid
• Check x-api-key header is correct

Publish/Unpublish Not Working

• Post must exist first
• Check status before and after operation
• published_at is set/unset accordingly
