Instagram Poster

What This Does

Posts carousels and Reels directly to Instagram via the Graph API. Uploads media to Vercel Blob for public URLs, creates containers, and publishes - eliminating manual upload steps.

Supports:

• Carousels - 2-10 images, swipeable posts
• Reels - Short-form video (5-90 seconds)

Prerequisites

Before first use, ensure these are configured:

1. Environment variables (in ~/.zshrc):

   • BLOB_READ_WRITE_TOKEN - Vercel Blob storage token

2. Config file (~/.config/instagram-poster.yaml):

   • Contains Instagram access token and user ID
   • Created by running auth_setup.py (one-time OAuth)

Instructions - Carousels

Step 1: Locate Carousel Images

Find the most recent carousel folder in ~/Downloads/:

ls -td ~/Downloads/carousel* | head -1

Or use the specific folder if provided by the user.

Verify the images:

• Should contain 2-10 PNG images
• Named like CarouselName01.png, CarouselName02.png, etc.

Step 2: Get User Approval (REQUIRED)

Before posting, ALWAYS show this confirmation:

Ready to post carousel to Instagram:
- X images from ~/Downloads/carouselYYMMDD/
- Caption preview: [first 100 chars of caption...]

Post now? (y/n)

DO NOT proceed without explicit user approval.

Step 3: Execute Posting

Run the post_carousel.py script:

Option A: Direct caption

python3 /Users/eddale/Documents/GitHub/powerhouse-lab/skills/instagram-poster/tools/post_carousel.py \
  --folder <carousel_folder_path> \
  --caption "<caption_text>"

Option B: Using a template

python3 /Users/eddale/Documents/GitHub/powerhouse-lab/skills/instagram-poster/tools/post_carousel.py \
  --folder <carousel_folder_path> \
  --template carousel \
  --title "Your Headline Here" \
  --topic "business"

Caption options (in priority order):

1. If --template flag provided, render caption from template
2. If user provides --caption, use it directly
3. If carousel folder contains caption.txt, read it
4. Otherwise, ask user for caption

Step 4: Report Results

On success, display:

• Instagram post URL
• Number of images posted
• "Carousel is now live!"

On failure:

• Show error message
• Suggest checking token expiry if auth-related

Caption Templates

Use templates for consistent, high-performing captions. Templates live in resources/caption-templates.yaml.

Available Templates

Template Variables

If {cta} is not provided, the template's default CTA is used.

Using Templates

List available templates:

python3 .../post_carousel.py --list-templates

Post with template:

python3 .../post_carousel.py \
  --folder ~/Downloads/carousel260120 \
  --template educational \
  --title "The One Skill That Changes Everything" \
  --topic "business"

With custom CTA:

python3 .../post_carousel.py \
  --folder ~/Downloads/carousel260120 \
  --template promotional \
  --title "Build Your First SaaS" \
  --topic "saas" \
  --cta "Link in bio - doors close Friday"

When to Use Templates vs Direct Caption

• Use template: Consistent brand voice, quick posting, following best practices
• Use direct caption: One-off special posts, very specific messaging, A/B testing

Caption Guidelines (Manual)

When writing captions manually (without templates), keep them concise. The carousel slides do the heavy lifting.

Pattern:

[Hook - what's the one thing?]

[1-2 sentences expanding]

Save this for later.

Instructions - Reels

Step 1: Locate Video File

Find the Reel video file. Typically in a reels-builder output folder:

ls -td ~/Downloads/reels-builder-* | head -1

The video should be final.mp4 in that folder.

Video requirements:

• Duration: 5-90 seconds
• Format: MP4 or MOV
• Aspect ratio: 9:16 (portrait)
• Max size: 300MB

Step 2: Get User Approval (REQUIRED)

Before posting, ALWAYS show this confirmation:

Ready to post Reel to Instagram:
- Video: ~/Downloads/reels-builder-xxx/final.mp4 (X.X MB)
- Caption preview: [first 100 chars of caption...]

Post now? (y/n)

DO NOT proceed without explicit user approval.

Step 3: Execute Posting

Run the post_reel.py script:

python3 /Users/eddale/Documents/GitHub/powerhouse-lab/skills/instagram-poster/tools/post_reel.py \
  --video <video_file_path> \
  --caption "<caption_text>"

Caption options:

• If user provides caption, use it
• If reel folder contains caption.txt, read it
• Otherwise, ask user for caption

Step 4: Report Results

On success, display:

• Instagram Reel URL
• "Reel is now live!"

On failure:

• Show error message
• Video processing takes longer than images - if timeout, suggest checking Instagram directly

Caption Guidelines (Reels)

Reels captions can be longer since the video is the hook.

Pattern:

[Hook question or statement]

[Context about what they're watching]

[CTA - follow for more, link in bio, etc.]
