References
Load these reference files when you need detailed specs for each area:
- -
references/tools-setup.md — How to set up DanSUGC, Post-Bridge, and Gemini - INLINECODE1 — Platform safe areas and text positioning specs
- INLINECODE2 — All ffmpeg commands for trimming, scaling, text, concat, music
- INLINECODE3 — Duration rules, hook writing, caption formulas, output specs
Critical Rules
- 1. MAX 15 SECONDS per reel — non-negotiable for virality
- ALL text MUST use TikTok Sans font — no exceptions
- ALL text MUST be in the Green Zone — never in platform UI areas
- ONE video per ONE account — never schedule the same video to multiple accounts
- Always run Preflight (Step 0) first — verify all tools before work
- Always use Gemini 3.1 Flash Lite for video intelligence — model: INLINECODE4
- Never expose API keys in output — redact in logs, never print full keys
- Purchase videos from DanSUGC before downloading — users must purchase clips via the MCP tool before getting download URLs
Step 0: Preflight Check (MANDATORY)
Run this EVERY time before doing any work. Check all tools, fonts, and MCP connections.
0a. FFmpeg & FFprobe
CODEBLOCK1
0b. TikTok Sans Font
TikTok Sans is TikTok's official open-source font (SIL Open Font License 1.1). Required for all text overlays.
CODEBLOCK2
0c. MCP Connections
Verify required MCP servers are connected. If missing, load references/tools-setup.md for setup instructions.
CODEBLOCK3
0d. Gemini API Key
CODEBLOCK4
0e. Preflight Summary
CODEBLOCK5
All must show OK before proceeding.
Step 1: Source UGC Hooks from DanSUGC
Search for reaction clips matching your content's emotional tone. The best hooks are emotionally charged reactions.
Emotion Categories (ranked by engagement)
| Emotion | Best For | Search Terms |
|---|
| Shocked | Surprising reveals, stats | INLINECODE6 |
| Crying/Tears |
Emotional stories, relatable pain |
crying sad tears emotional |
|
Frustrated | Problem-agitate-solve content |
frustrated overwhelmed stressed |
|
Angry | Injustice, call-to-action |
angry upset outraged |
|
Happy/Excited | Wins, positive outcomes |
happy excited celebrating |
|
Confused | Educational content, myth-busting |
confused puzzled thinking |
Search Strategy
Use semantic search for best results:
CODEBLOCK6
Purchase & Download Workflow
- 1. Search for matching clips
- Review results — check duration, emotion, virality score
- Check balance with INLINECODE12
- Purchase selected clips with INLINECODE13
- Download using the URLs returned from purchase
CODEBLOCK7
Hook Selection Rules
- - Duration: Prefer clips 5-14 seconds (will be trimmed to ~5s)
- Virality score: Prefer 70+ for proven engagement
- Emotion match: Match the hook emotion to the text overlay emotion
- Vertical preferred: 1080x1920 clips need no cropping
- Landscape OK: Will be center-cropped to vertical
Step 2: Analyze & Split Demos with Gemini
Use Gemini 3.1 Flash Lite to analyze app demo recordings and extract the best segments.
2a. Extract Keyframes
CODEBLOCK8
2b. Gemini Video Analysis
CODEBLOCK9
2c. Auto-Cut Clips
For detailed ffmpeg patterns for trimming, scaling, speed-up, and concat, load ./references/ffmpeg-patterns.md.
Short clips (natural speed, 7-9s):
CODEBLOCK10
Speed-up clips (20-30s source -> 7-9s output) — MUST use two-pass:
CODEBLOCK11
2d. Build Clip Library
CODEBLOCK12
Step 3: Assemble Reels
Combine hooks + demos + text + music into 15-second reels.
3a. The 15-Second Formula
CODEBLOCK13
3b. Prepare Hook Clip
Landscape source (center crop):
CODEBLOCK14
Vertical source (scale + pad):
CODEBLOCK15
3c. Concatenate Hook + Demo
CODEBLOCK16
3d. Add Text Overlays
ALL text must use TikTok Sans and be placed within the Green Zone. For full specs, load ./references/green-zone.md.
For text WITH apostrophes — use textfile= to avoid escaping issues:
CODEBLOCK17
For text WITHOUT apostrophes — use inline text=:
CODEBLOCK18
Escape colons in drawtext with \\: (e.g., "10\\:00 AM").
3e. Add Music
CODEBLOCK19
3f. Validate Duration (MANDATORY)
CODEBLOCK20
If over 15.0s: trim the demo clip or speed it up. NEVER deliver over 15 seconds.
Step 4: Publish via Post-Bridge
For full setup instructions, load ./references/tools-setup.md.
4a. Upload Videos
Videos need public URLs. Use tmpfiles.org for temporary hosting:
CODEBLOCK21
4b. Schedule Posts
CODEBLOCK22
Distribution rules:
- - ONE unique video per account — never post the same video to multiple accounts
- Stagger posting times by 5 minutes between accounts
- Drafts (
is_draft: true) cannot be updated/deleted via API
4c. Caption Formula
CODEBLOCK23
Step 5: Track Performance via DanSUGC Analytics Proxy
Social media analytics are included with your DanSUGC API key — no extra setup needed. DanSUGC proxies ScrapCreators data at $0.02/request from your existing balance. Auth is handled automatically by the MCP server.
CODEBLOCK24
Error codes:
- -
402 — Insufficient DanSUGC balance (top up credits) - INLINECODE20 — API key not linked to a user account
- INLINECODE21 — Upstream unreachable (auto-refunded, safe to retry)
Winner Thresholds (24-48h)
| Metric | Good | Great | Viral |
|---|
| Views | 10K+ | 100K+ | 1M+ |
| Like ratio |
5%+ | 10%+ | 15%+ |
| Comment ratio | 0.5%+ | 1%+ | 2%+ |
| Share ratio | 0.3%+ | 1%+ | 3%+ |
Replicate Winners
- 1. Same hook emotion + different UGC creator
- Same text style + same demo angle
- Same music + spread across accounts
- Search for more clips: INLINECODE22
Step 6: Format Research — Find Viral Formats for Any Niche
When users ask for format ideas (e.g., "find me format ideas for beef liver supplements on TikTok"), use the DanSUGC MCP tools to research what's working in that niche across TikTok and Instagram.
6a. Search for Niche Content
Search TikTok and Instagram for top-performing content in the user's niche:
CODEBLOCK25
Run multiple keyword variations to cast a wider net. For example, for "beef liver supplements":
- - INLINECODE23
- INLINECODE24
- INLINECODE25
- INLINECODE26 (known creators in the niche)
- INLINECODE27
6b. Find Top Creators in the Niche
Identify creators who are crushing it, then pull their most popular videos:
CODEBLOCK26
6c. Analyze & Present Format Ideas
From the search results, extract and present 4-5 distinct format ideas. For each format:
CODEBLOCK27
6d. Format Research Strategy
Search in this order for best results:
- 1. Broad niche search —
keyword search for the main niche term - Specific product search —
keyword search for the exact product/brand - Creator discovery —
user search to find niche influencers - Creator deep-dive —
profile videos sorted by popular for top 2-3 creators - Cross-platform — Repeat key searches on Instagram for format diversity
What to look for in results:
- - Videos with unusually high engagement (likes/views ratio > 10%)
- Recurring formats across multiple creators (validates the format works)
- Content styles: UGC reactions, before/after, POV, tutorials, testimonials, unboxing, "day in my life"
- Hook patterns: text overlays, opening lines, visual hooks
- Duration sweet spots in the niche
Step 7: Hook Research — Find Winning Text Hooks
When users ask for hook ideas, use the DanSUGC MCP tools to find text hooks proven to work in the niche.
7a. Search for Hook Inspiration
CODEBLOCK28
7b. Extract & Categorize Hooks
From the search results, extract text hooks from video descriptions, captions, and titles. Group them by type:
| Category | Pattern | Example |
|---|
| "When..." hooks | When [relatable situation]... | "When you've tried everything but nothing works" |
| POV hooks |
POV: [scenario] | "POV: you finally tried organ supplements" |
|
Statistic hooks | [Number] [claim] | "90% of people are deficient in this" |
|
Question hooks | [Provocative question]? | "Why is nobody talking about this?" |
|
Confession hooks | I [honest admission] | "I used to think supplements were a scam" |
|
"Nobody..." hooks | Nobody talks about [truth] | "Nobody tells you this about iron deficiency" |
|
Challenge hooks | [Dare or challenge] | "Try this for 30 days and watch what happens" |
|
Before/After hooks | [Before state] → [After state] | "Day 1 vs Day 30 on beef liver" |
7c. Present Hook Ideas
For each hook, provide:
CODEBLOCK29
7d. Hook Research Strategy
To find hooks that match a specific format:
- 1. Search for the format keyword (e.g., "supplement review TikTok")
- Look at the top 10-20 results
- Extract the first line of each caption — this is usually the hook
- Cross-reference with engagement: hooks from high-performing videos are proven
To find hooks for a specific brand/product:
- 1. Search for the brand name directly
- Search for the product category + emotional keywords
- Search for competitor brand names
Hook quality signals:
- - High engagement ratio (likes/views > 10%)
- Many comments (comments indicate the hook triggered a response)
- Hook text matches the emotional tone of the video
- Short and scannable (3-7 words per line, max 3 lines)
Troubleshooting
"No token data found" for DanSUGC MCP:
- - Re-register: INLINECODE32
- Restart Claude Code after adding
Apostrophes breaking text overlays:
- - Use
textfile=/tmp/mytext.txt instead of inline INLINECODE34 - Write text to file first: INLINECODE35
Speed-up clips output wrong duration:
- - Always use two-pass: trim first with
-c copy, then speed up with INLINECODE37 - Never combine
-ss/-to with setpts in a single pass
Drafts can't be updated/deleted in Post-Bridge:
- - API limitation — drafts are immutable. Create a new scheduled post instead.
