Viraloop

Analyze any website and generate a 6-slide carousel for TikTok/Instagram with visual coherence. Posts directly to your feed (no drafts) with auto trending music. Both APIs (Gemini + upload-post.com) have free plans — no credit card needed to start.

Philosophy: Daily Automated Loop

The key to growth is consistency + learning. This skill is designed to run every day, fully autonomous. The agent executes the entire pipeline without asking for confirmation — from research to publishing — and only notifies you at the end with the published TikTok and Instagram URLs.

1. Post 1 carousel per day - Consistency beats virality
2. Track everything - Every post generates data
3. Learn from data - What hooks work? What times? What visuals?
4. Iterate and improve - Each carousel is better than the last

Day 1: Post → Analyze → Learn
Day 2: Post (improved) → Analyze → Learn  
Day 3: Post (better) → Analyze → Learn
...
Day 30: You have 30 data points and a refined strategy

The skill maintains a learnings.json that accumulates insights across all posts:

• Best performing hooks
• Optimal posting times
• Visual styles that work
• CTAs that convert

This is not a one-shot tool. It's a growth engine.

Before You Start: Account Warmup

If your TikTok or Instagram accounts are brand new, don't post carousels on day one. Both platforms throttle reach on fresh accounts that jump straight into publishing content.

TikTok (7-14 days warmup)

• Spend 30-60 minutes per day using TikTok normally: scroll, like (about 1 in 10 videos), follow accounts in your niche
• Wait until your For You page is dominated by content in your niche — that means the algorithm has profiled your account
• Only then start posting. Your first posts will reach the right audience instead of getting buried

Instagram (5-7 days warmup)

• Browse Reels and the Explore page daily, engage with content in your niche
• Follow relevant accounts, like and comment genuinely
• Post 2-3 stories before your first carousel to signal the account is active

Why this matters

Platforms flag accounts that go from zero activity to automated posting. A warmed-up account gets 5-10x more initial reach than a cold one. This step is boring but it's the difference between 500 views and 50,000 views on your first carousel.

If your accounts are already active and established, skip this and go straight to Quick Start.

Quick Start

The agent should run the full pipeline automatically. Do not ask for confirmation between steps.

# 0. FIRST: Check analytics from previous posts + learn
#    (Skip this only on the very first run when there are no posts yet)
UPLOADPOST_TOKEN="your-token" bash {baseDir}/scripts/check-analytics.sh 7
node {baseDir}/scripts/learn-from-analytics.js

# 1. Full business research
node {baseDir}/scripts/analyze-web.js https://your-website.com

# 2. Read learnings.json and use best hooks/times/styles for this carousel
#    → Pick a hook style from bestHooks (or try a variation)
#    → Use recommended posting time
#    → Apply any insights from recommendations

# 3. Generate slides with visual coherence
GEMINI_API_KEY="your-key" bash {baseDir}/scripts/generate-slides.sh

# 4. Review slides with vision → auto-fix any broken ones
#    Agent uses its image-to-text model to verify each slide
#    If any slide has issues (cut text, bad quality, wrong spelling):
#      → Regenerate ONLY that slide automatically
#      → Re-verify until all 6 slides pass

# 5. Publish to TikTok + Instagram
UPLOADPOST_TOKEN="your-token" bash {baseDir}/scripts/publish-carousel.sh

The agent only notifies the user at the very end, with the published TikTok and Instagram post URLs. Everything else runs autonomously.

How Learnings Improve Each Carousel

The learnings.json file grows smarter with every post. Before generating slides, the agent reads it and applies:

• Best hooks: Use hook styles that got the most views. Try variations of winners.
• Best times: Schedule publishing at the time that historically gets most reach.
• Best days: Prefer days that perform better.
• Low performers: Avoid hook styles that consistently underperform.
• Engagement tips: If engagement is low, use more provocative hooks or different visual styles.

This means carousel #30 will have dramatically better prompts than carousel #1.

Agent Execution Schedule: The agent shouldn't just run at a random time. It should read learnings.json, look at the bestTimes array, and automatically adjust its own cron/automation schedule so that tomorrow's execution happens right at the optimal publishing time.

First runs (no data yet): The first few times there won't be analytics data — that's fine. The agent uses the default hooks from analyze-web.js and the generic recommendations. After 5-10 posts, learnings.json will have enough data to start making meaningful recommendations. The more you post, the smarter it gets.

Image Model

Uses gemini-3.1-flash-image-preview to generate slides.

• Local script: {baseDir}/scripts/generate_image.py
• Supports image-to-image for visual coherence between slides

Step 1: Full Research (analyze-web.js)

Performs COMPLETE business investigation:

1. Brand Analysis

• Brand name (from domain or title)
• Logo (URL or SVG)
• CSS colors (background, primary, links, headings)
• Typography (body font, heading font)
• Favicon

2. Content Analysis

• Headline and tagline
• All headings (page structure)
• Features/benefits (title + description)
• Pricing/plans
• Testimonials
• Stats/metrics
• CTAs
• Meta tags (title, description, og:image)

3. Internal Pages

• Navigates pricing, features, about, testimonials
• Extracts additional content from each page

4. Competitor Detection

• Searches for known competitor mentions in content
• List of 20+ known SaaS competitors (Buffer, Hootsuite, Later, etc.)
• Detects "vs", "alternative", "compare" sections
• No external searches required - all from the website itself

5. Storytelling

• Detects business type (SaaS, ecommerce, app)
• Detects niche (social-media-tools, developer-tools, etc.)
• Generates hooks based on customer pain points
• Defines pain points from features
• Creates transformation narrative (before → after)

6. Visual Context

• Brand colors in CSS format
• Color description for prompts
• Typography for slides
• Image themes based on niche
• Style guide for coherence

Output: /tmp/carousel/analysis.json

Step 2: Generate Slides (generate-slides.sh)

Generates 6 slides with visual coherence using image-to-image:

Visual Coherence

• Slide 1 generates the base style (colors, typography, mood)
• Slides 2-6 use image-to-image with slide 1 as reference
• Maintains same color palette, fonts, and aesthetic

Prompts per Slide

Each slide has:

• Text: The main message
• Scene: Detailed visual description for background
• Style: Based on brand analysis

Output:

• /tmp/carousel/slide-{1-6}.jpg
• /tmp/carousel/caption.txt

Step 3: Review with Vision (Autonomous)

After generating, the agent MUST review each slide using its vision/image-to-text model. This step is fully automatic — do not ask the user to review.

For each slide, verify:

• ✓ Text is fully legible and correct
• ✓ No words cut off at edges
• ✓ Product name spelled correctly
• ✓ Visual coherence between all slides
• ✓ No text in bottom 20% (TikTok controls area)
• ✓ Acceptable image quality (not blurry or distorted)

If any slide fails: Regenerate ONLY that specific slide automatically. Use the same input image that was used when originally generating it:

• Slide 1: no input image (it establishes the style)
• Slides 2-6: always use slide-1.jpg as --input-image (the original reference)

Re-verify after regenerating. Repeat until all 6 slides pass. Do not ask the user — fix it automatically.

Image Format

• Resolution: 768x1376 (9:16 vertical ratio)
• Format: JPG (TikTok does NOT accept PNG)
• Text: Large, bold, with shadow for readability
• Background: Scene relevant to the business, not just solid colors

Step 4: Publish to TikTok + Instagram (publish-carousel.sh)

Publishes the carousel directly to the TikTok and Instagram feed using Upload-Post API.

UPLOADPOST_TOKEN="your-token" bash {baseDir}/scripts/publish-carousel.sh

Endpoint: POST /api/upload_photos

• Docs: https://docs.upload-post.com/api/upload-photo

Parameters sent:

• platform[]=tiktok + platform[]=instagram
• auto_add_music=true - Adds music on TikTok automatically
• tiktok_title - Short title (max 90 chars) + hashtags
• title - Full caption for Instagram
• privacy_level=PUBLIC_TO_EVERYONE
• media_type=IMAGE - Photo carousel on Instagram
• async_upload=true - Process in background
• photos[] - The 6 slides JPG

⚠️ IMPORTANT Instagram: After publishing, user must go to Instagram and add viral music manually:

1. Open Instagram → Profile → The post
2. Edit → Add music
3. Search for trending/viral song

Output: Saves request_id in post-info.json for tracking.

Step 5: Analyze Performance (check-analytics.sh)

Gets TikTok and Instagram analytics to see what works.

UPLOADPOST_TOKEN="your-token" bash {baseDir}/scripts/check-analytics.sh 7

Endpoints used:

1. Profile analytics:

   GET /api/analytics/{user}?platforms=tiktok
   

   → Followers, likes, comments, shares, impressions

2. Total impressions:

   GET /api/uploadposts/total-impressions/{user}?platform=tiktok&breakdown=true
   

   → Total views per day

3. Per-post analytics:

   GET /api/uploadposts/post-analytics/{request_id}
   

   → Views, likes, comments for the specific carousel (TikTok + Instagram)

Docs: https://docs.upload-post.com/api/get-analytics

Step 6: Learn and Improve (learn-from-analytics.js)

Analyzes data and saves learnings for future carousels. This must run at the START of every daily loop, not just at the end.

node {baseDir}/scripts/learn-from-analytics.js

Generates/updates:

• learnings.json - Accumulated knowledge base
• Best hooks (those generating most views)
• Optimal posting times and days
• Engagement rate tracking
• Recommendations for the next carousel

The agent must read learnings.json before generating each new carousel and use the insights to pick better hooks, avoid underperforming styles, and schedule at optimal times.

Daily Loop (Complete Flow)

This is the exact sequence the agent runs every day, fully autonomous:

# STEP 0: Learn from previous posts (skip on first run)
UPLOADPOST_TOKEN="..." UPLOADPOST_USER="myuser" bash {baseDir}/scripts/check-analytics.sh 7
node {baseDir}/scripts/learn-from-analytics.js
# → Agent reads learnings.json and picks the best hook style
# → CRITICAL: Agent checks bestTimes and schedules ITS OWN NEXT EXECUTION for that exact hour tomorrow

# STEP 1: Research business
node {baseDir}/scripts/analyze-web.js https://my-product.com

# STEP 2: Generate slides (using insights from learnings)
GEMINI_API_KEY="..." bash {baseDir}/scripts/generate-slides.sh

# STEP 3: Review with vision → auto-fix broken slides
# Agent checks each slide, regenerates any that fail

# STEP 4: Publish
UPLOADPOST_TOKEN="..." UPLOADPOST_USER="myuser" bash {baseDir}/scripts/publish-carousel.sh

# → Notify user ONLY here, with TikTok + Instagram URLs
