### DanSUGC Posting API Reference

If you get stuck with any posting operation, consult these resources:

- **API docs (LLM-friendly):** https://dansugc.com/llms.txt
- **Interactive docs:** https://dansugc.com/docs

## Critical Rules

1. **MAX 15 SECONDS per reel** — non-negotiable for virality
2. **ALL text MUST use TikTok Sans font** — no exceptions
3. **ALL text MUST be in the Green Zone** — never in platform UI areas
4. **ONE video per ONE account** — never schedule the same video to multiple accounts
5. **Always run Preflight (Step 0) first** — verify all tools before work
6. **Always use Gemini 3.1 Flash Lite for video intelligence** — model: `gemini-3.1-flash-lite-preview`
7. **Never expose API keys in output** — redact in logs, never print full keys
8. **Purchase videos from DanSUGC before downloading** — users must purchase clips via the MCP tool before getting download URLs
9. **NEVER construct dansugc.com URLs for downloading** — the only valid download URLs are the storage URLs returned by `mcp__dansugc__purchase_videos`. Do NOT fabricate URLs like `/api/broll/download`, `/api/v1/broll/download`, or any other dansugc.com download path. These are internal browser routes that require session cookies and will fail with API keys.

---

## Step 0: Preflight Check (MANDATORY)

Run this EVERY time before doing any work. Check all tools, fonts, and MCP connections.

### 0a. FFmpeg & FFprobe

```bash
if command -v ffmpeg &>/dev/null; then
  echo "ffmpeg: OK ($(ffmpeg -version 2>&1 | head -1))"
else
  echo "ffmpeg: MISSING — installing..."
  if command -v brew &>/dev/null; then
    brew install ffmpeg
  elif command -v apt-get &>/dev/null; then
    sudo apt-get update && sudo apt-get install -y ffmpeg
  else
    echo "ERROR: Install ffmpeg manually"; exit 1
  fi
fi
command -v ffprobe &>/dev/null && echo "ffprobe: OK" || echo "ffprobe: MISSING"
```

### 0b. TikTok Sans Font

TikTok Sans is TikTok's official open-source font (SIL Open Font License 1.1). Required for all text overlays.

```bash
if [ -f "$HOME/Library/Fonts/TikTokSansDisplayBold.ttf" ] || [ -f "/usr/share/fonts/TikTokSansDisplayBold.ttf" ] || [ -f "$HOME/.local/share/fonts/TikTokSansDisplayBold.ttf" ]; then
  echo "TikTok Sans: OK"
else
  echo "TikTok Sans: MISSING — installing..."
  if [[ "$(uname)" == "Darwin" ]]; then
    FONT_DIR="$HOME/Library/Fonts"
  else
    FONT_DIR="$HOME/.local/share/fonts"
  fi
  mkdir -p "$FONT_DIR"
  cd /tmp
  curl -L -o tiktoksans.zip "https://www.cufonfonts.com/download/font/tiktok-sans"
  unzip -o tiktoksans.zip -d tiktoksans_extracted
  cp tiktoksans_extracted/TikTokSans*.ttf "$FONT_DIR/"
  rm -rf tiktoksans_extracted tiktoksans.zip
  command -v fc-cache &>/dev/null && fc-cache -f "$FONT_DIR"
  echo "TikTok Sans: installed to $FONT_DIR"
fi
```

### 0c. MCP Connections

Verify required MCP servers are connected. If missing, load `references/tools-setup.md` for setup instructions.

```
Required MCP Servers:
  dansugc — search_videos, purchase_videos, create_post, analytics (all-in-one)
```

### 0d. Gemini API Key

```bash
if [ -n "$GEMINI_API_KEY" ]; then
  echo "Gemini API: OK (key set)"
else
  echo "Gemini API: MISSING — set GEMINI_API_KEY environment variable"
  echo "Get your key at: https://aistudio.google.com/apikey"
fi
```

### 0e. Preflight Summary

```bash
echo "=== REELCLAW PREFLIGHT ==="
echo "ffmpeg:      $(command -v ffmpeg &>/dev/null && echo 'OK' || echo 'MISSING')"
echo "ffprobe:     $(command -v ffprobe &>/dev/null && echo 'OK' || echo 'MISSING')"
FONT_OK="MISSING"
for dir in "$HOME/Library/Fonts" "$HOME/.local/share/fonts" "/usr/share/fonts"; do
  [ -f "$dir/TikTokSansDisplayBold.ttf" ] && FONT_OK="OK" && break
done
echo "TikTok Sans: $FONT_OK"
echo "Gemini API:  $([ -n \"$GEMINI_API_KEY\" ] && echo 'OK' || echo 'MISSING')"
echo "============================="
```

**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 | `shocked surprised reaction` |
| **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:

```
mcp__dansugc__search_videos(semantic_search="shocked woman reacting to phone screen")
mcp__dansugc__search_videos(emotion="shocked", gender="female", limit=10)
mcp__dansugc__search_videos(semantic_search="crying emotional reaction", min_virality=75)
```

### Purchase & Download Workflow

1. **Search** for matching clips
2. **Review** results — check duration, emotion, virality score
3. **Check balance** with `mcp__dansugc__get_balance`
4. **Purchase** selected clips with `mcp__dansugc__purchase_videos`
5. **Download** using the **storage URLs** returned in the purchase response's `download_url` field

```bash
# The download_url from purchase_videos is a STORAGE URL (e.g., https://storage.example.com/full/xyz.mp4)
# It is NOT a dansugc.com URL. Never construct download URLs yourself.
curl -L -o hook-clip.mp4 "DOWNLOAD_URL_FROM_PURCHASE_RESPONSE"
```

**IMPORTANT:** If `purchase_videos` does not return a `download_url`, ask the user to check their DanSUGC dashboard. Do NOT attempt to guess or construct a download URL.

### 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

```bash
ffmpeg -y -hide_banner -loglevel error \
  -i "DEMO.mp4" \
  -vf "fps=1/5,scale=540:-1" \
  "keyframes/frame_%03d.jpg"
```

### 2b. Gemini Video Analysis

```bash
# Direct video upload to Gemini (preferred)
FILE_URI=$(curl -s -X POST \
  "https://generativelanguage.googleapis.com/upload/v1beta/files?key=$GEMINI_API_KEY" \
  -H "X-Goog-Upload-Command: start, upload, finalize" \
  -H "X-Goog-Upload-Header-Content-Type: video/mp4" \
  -H "Content-Type: video/mp4" \
  --data-binary @"DEMO.mp4" | python3 -c "import sys,json; print(json.load(sys.stdin)['file']['uri'])")

curl -s "https://generativelanguage.googleapis.com/v1beta/models/gemini-3.1-flash-lite-preview:generateContent?key=$GEMINI_API_KEY" \
  -H "Content-Type: application/json" \
  -d "{
    \"contents\": [{
      \"parts\": [
        {\"text\": \"Analyze this app demo. Identify the best 7-9 second clips and 20-30 second segments for speed-up. Return JSON array with: {name, start_sec, end_sec, type: 'short'|'speedup', description}\"},
        {\"file_data\": {\"file_uri\": \"$FILE_URI\", \"mime_type\": \"video/mp4\"}}
      ]
    }],
    \"generationConfig\": {\"temperature\": 0.2, \"response_mime_type\": \"application/json\"}
  }"
```

### 2c. Auto-Cut Clips

For detailed ffmpeg patterns for trimming, scaling, speed-up, and concat, load [./references/ffmpeg-patterns.md](./references/ffmpeg-patterns.md).

**Short clips (natural speed, 7-9s):**
```bash
VF="scale=1080:1920:force_original_aspect_ratio=decrease,pad=1080:1920:(ow-iw)/2:(oh-ih)/2:color=black,fps=30"

ffmpeg -y -hide_banner -loglevel error \
  -i "DEMO.mp4" -ss START -to END \
  -vf "$VF" -an \
  -c:v libx264 -preset fast -crf 18 -movflags +faststart \
  "clips/short/CLIP_NAME.mp4"
```

**Speed-up clips (20-30s source -> 7-9s output) — MUST use two-pass:**
```bash
# Pass 1: Trim segment
ffmpeg -y -hide_banner -loglevel error \
  -i "DEMO.mp4" -ss START -to END \
  -c copy "/tmp/segment.mp4"

# Pass 2: Speed up + scale (e.g., 30s -> 8.5s = setpts=0.283*PTS)
ffmpeg -y -hide_banner -loglevel error \
  -i "/tmp/segment.mp4" \
  -vf "setpts=0.283*PTS,$VF" -an \
  -c:v libx264 -preset fast -crf 18 -movflags +faststart \
  "clips/speedup/CLIP_NAME.mp4"
```

### 2d. Build Clip Library

```
project/
  clips/
    short/          # 7-9s natural speed clips
    speedup/        # 7-9s sped-up clips
  hooks/            # Downloaded UGC reaction clips
  finals/           # Completed reels
  music/            # Audio tracks
  clip-manifest.md  # Index of all clips with descriptions
```

---

## Step 3: Assemble Reels

Combine hooks + demos + text + music into 15-second reels.

### 3a. The 15-Second Formula

```
Hook clip:    ~5 seconds  (UGC reaction — attention grabber)
Demo clip:    ~10 seconds (app demo — the product showcase)
Total:         15 seconds MAX
```

### 3b. Prepare Hook Clip

**Landscape source (center crop):**
```bash
ffmpeg -y -hide_banner -loglevel error \
  -i "hook.mp4" -ss 1 -to 6 \
  -vf "scale=1080:1920:force_original_aspect_ratio=increase,crop=1080:1920,setsar=1,fps=30" \
  -an -c:v libx264 -preset fast -crf 18 -movflags +faststart \
  "hook-trimmed.mp4"
```

**Vertical source (scale + pad):**
```bash
ffmpeg -y -hide_banner -loglevel error \
  -i "hook.mp4" -ss 1 -to 6 \
  -vf "scale=1080:1920:force_original_aspect_ratio=decrease,pad=1080:1920:(ow-iw)/2:(oh-ih)/2:color=black,setsar=1,fps=30" \
  -an -c:v libx264 -preset fast -crf 18 -movflags +faststart \
  "hook-trimmed.mp4"
```

### 3c. Concatenate Hook + Demo

```bash
cat > /tmp/concat.txt << EOF
file 'hook-trimmed.mp4'
file 'demo-trimmed.mp4'
EOF

ffmpeg -y -hide_banner -loglevel error \
  -f concat -safe 0 -i /tmp/concat.txt \
  -c:v libx264 -preset fast -crf 18 -movflags +faststart \
  "reel-notext.mp4"
```

### 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](./references/green-zone.md).

**For text WITH apostrophes** — use `textfile=` to avoid escaping issues:
```bash
printf "When nothing's wrong" > /tmp/hook_line1.txt

ffmpeg -y -hide_banner -loglevel error -i "reel-notext.mp4" \
  -vf "drawtext=textfile=/tmp/hook_line1.txt:\
    fontfile=$HOME/Library/Fonts/TikTokSansDisplayBold.ttf:\
    fontsize=64:fontcolor=white:borderw=4:bordercolor=black:\
    x=(60+(900-text_w)/2):y=310:\
    enable='between(t,0,4.5)'" \
  -c:v libx264 -preset fast -crf 18 -c:a copy -movflags +faststart \
  "reel-text.mp4"
```

**For text WITHOUT apostrophes** — use inline `text=`:
```bash
ffmpeg -y -hide_banner -loglevel error -i "reel-notext.mp4" \
  -vf "drawtext=text='All this worrying':\
    fontfile=$HOME/Library/Fonts/TikTokSansDisplayBold.ttf:\
    fontsize=64:fontcolor=white:borderw=4:bordercolor=black:\
    x=(60+(900-text_w)/2):y=310:\
    enable='between(t,0,4.5)'" \
  -c:v libx264 -preset fast -crf 18 -c:a copy -movflags +faststart \
  "reel-text.mp4"
```

**Escape colons in drawtext with `\\:`** (e.g., "10\\:00 AM").

### 3e. Add Music

```bash
ffmpeg -y -hide_banner -loglevel error \
  -i "reel-text.mp4" -i "track.mp3" \
  -map 0:v -map 1:a \
  -af "afade=t=in:st=0:d=0.5,afade=t=out:st=14:d=1,volume=0.8" \
  -c:v copy -c:a aac -b:a 128k \
  -shortest -movflags +faststart \
  "reel-final.mp4"
```

### 3f. Validate Duration (MANDATORY)

```bash
ffprobe -v quiet -print_format json -show_entries format=duration "reel-final.mp4" | \
  python3 -c "import sys,json; d=float(json.load(sys.stdin)['format']['duration']); \
  print(f'Duration: {d:.1f}s — {\"OK\" if d <= 15.0 else \"TOO LONG — must re-edit\"}')"
```

**If over 15.0s:** trim the demo clip or speed it up. NEVER deliver over 15 seconds.

---

## Step 4: Virality Score (Gemini Video Analysis)

Score reels before publishing using Gemini's video understanding. Upload the video to the Gemini File API, get a 0-100 virality score across 7 criteria. **Only publish reels scoring 70+.**

For full scoring scripts (single + batch), prompt template, and improvement guide, load [./references/virality-scoring.md](./references/virality-scoring.md).

### Quick Score (Single Reel)

```bash
# Upload to Gemini
FILE_URI=$(curl -s -X POST \
  "https://generativelanguage.googleapis.com/upload/v1beta/files?key=$GEMINI_API_KEY" \
  -H "X-Goog-Upload-Command: start, upload, finalize" \
  -H "X-Goog-Upload-Header-Content-Type: video/mp4" \
  -H "Content-Type: video/mp4" \
  --data-binary @"reel-final.mp4" | python3 -c "import sys,json; print(json.load(sys.stdin)['file']['uri'])")

sleep 4  # Wait for processing

# Score — returns JSON with overall_score + 7 sub-scores + improvement tips
curl -s "https://generativelanguage.googleapis.com/v1beta/models/gemini-3.1-flash-lite-preview:generateContent?key=$GEMINI_API_KEY" \
  -H "Content-Type: application/json" \
  -d "{...}"  # See references/virality-scoring.md for full prompt
```

### Score Criteria

| Criterion | What It Measures |
|-----------|-----------------|
| **hook_strength** | Opening 1-3 seconds — does it stop the scroll? |
| **emotional_impact** | Does it trigger relatability, shock, humor, empathy? |
| **pacing_flow** | Tight cuts, no dead time, snappy feel? |
| **text_readability** | Clear text, good positioning, high contrast? |
| **scroll_stop_power** | Would someone stop mid-scroll on the first frame? |
| **completion_likelihood** | Will viewers watch to the end? |
| **shareability** | Would someone send this to a friend? |

### Score Thresholds

| Score | Action |
|-------|--------|
| **85+** | Publish immediately — prioritize for best account |
| **70-84** | Publish — minor tweaks optional |
| **55-69** | Rework hook or pacing before publishing |
| **<55** | Re-edit significantly or discard |

### Batch Score

For scoring entire directories, use the Python batch scorer in [./references/virality-scoring.md](./references/virality-scoring.md). It handles uploads, rate limits, and outputs a ranked scorecard.

---

## Step 5: Publish via DanSUGC Posting

DanSUGC handles TikTok and Instagram publishing natively — no third-party tools needed. Requires a **DanSUGC Posting subscription** (separate from B-Roll credits — check your dashboard).

### 5a. Check Subscription

```
mcp__dansugc__check_posting_subscription()
```

If not subscribed, direct the user to [dansugc.com/dashboard](https://dansugc.com/dashboard) to activate a Posting plan.

### 5b. List Connected Accounts

```
mcp__dansugc__list_posting_accounts()
```

Returns connected TikTok and Instagram accounts with their IDs, usernames, follower counts. Note the `id` for each account — needed when creating posts.

### 5c. Upload Video (Get Public URL)

Videos need a public URL. Use tmpfiles.org for temporary hosting:

```bash
url=$(curl -s -F "file=@reel-final.mp4" https://tmpfiles.org/api/v1/upload | \
  python3 -c "import sys,json; u=json.load(sys.stdin)['data']['url']; \
  print(u.replace('tmpfiles.org/', 'tmpfiles.org/dl/'))")
echo "Public URL: $url"
```

### 5d. Schedule or Publish Post

```
mcp__dansugc__create_post(
  content="Hook text...\n\nCaption body...\n\n#hashtag1 #hashtag2 #fyp",
  media_urls=["PUBLIC_VIDEO_URL"],
  account_ids=["ACCOUNT_ID"],
  scheduled_for="2026-03-25T18:00:00Z",
  timezone="America/New_York"
)
```

Set `publish_now=true` to post immediately instead of scheduling.

**Distribution rules:**
- ONE unique video per account — never post the same video to multiple accounts
- Stagger posting times by 5 minutes between accounts

### 5e. Caption Formula

```
[Hook text — the emotional line from the video]

[1-2 sentences connecting the emotion to your product/solution]

#hashtag1 #hashtag2 #hashtag3 #hashtag4 #hashtag5 #fyp
```

### 5f. Verify Post Status

```
mcp__dansugc__list_posts()
```

Status values: `draft`, `scheduled`, `published`, `failed`.

---

## Step 6: 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.

```
# Get TikTok video stats
mcp__dansugc__scrapecreators_raw(path="v1/tiktok/video", params={url: "VIDEO_URL"})

# Search TikTok videos by keyword
mcp__dansugc__tiktok_search_videos(query="KEYWORD")

# Get TikTok profile videos (sorted by popular)
mcp__dansugc__tiktok_user_videos(handle="USERNAME", sort_by="popular")

# Search Instagram reels
mcp__dansugc__instagram_search_reels(query="KEYWORD")
```

**Error codes:**
- `402` — Insufficient DanSUGC balance (top up credits)
- `403` — API key not linked to a user account
- `502` — 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
2. Same text style + same demo angle
3. Same music + spread across accounts
4. Search for more clips: `mcp__dansugc__search_videos(emotion="shocked", min_virality=70)`

---

## Step 7: 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:

```
# Search TikTok for niche keywords
mcp__dansugc__tiktok_search_videos(query="NICHE_KEYWORD")

# Search Instagram reels for same niche
mcp__dansugc__instagram_search_reels(query="NICHE_KEYWORD")
```

**Run multiple keyword variations** to cast a wider net. For example, for "beef liver supplements":
- `beef liver supplement`
- `beef liver capsules`
- `organ supplements`
- `liver king` (known creators in the niche)
- `desiccated liver`

### 6b. Find Top Creators in the Niche

Identify creators who are crushing it, then pull their most popular videos:

```
# Search for creators in the niche
mcp__dansugc__tiktok_search_users(query="NICHE_KEYWORD")

# Get their top-performing videos
mcp__dansugc__tiktok_user_videos(handle="CREATOR_USERNAME", sort_by="popular")

# Get Instagram creator reels
mcp__dansugc__instagram_user_reels(handle="CREATOR_USERNAME")
```

### 6c. Analyze & Present Format Ideas

From the search results, extract and present **4-5 distinct format ideas**. For each format:

```markdown
### Format [N]: [Format Name]

**Description:** What the format looks like and how it works
**Example:** [Link or description of a top-performing video using this format]
**Stats:** [Views, likes, engagement rate from the search results]
**Why it works:** [Brief psychology — why this format resonates]
**How to replicate with ReelClaw:**
  - Hook type: [emotion — shocked, crying, etc.]
  - Text hook style: [e.g., "When..." question, bold statement, statistic]
  - Demo content: [what to show in the demo portion]
  - Music vibe: [energetic, moody, trending sound]
```

### 6d. Format Research Strategy

**Search in this order for best results:**

1. **Broad niche search** — `keyword search` for the main niche term
2. **Specific product search** — `keyword search` for the exact product/brand
3. **Creator discovery** — `user search` to find niche influencers
4. **Creator deep-dive** — `profile videos sorted by popular` for top 2-3 creators
5. **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 8: 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

```
# Search TikTok for niche content — hooks live in video descriptions/captions
mcp__dansugc__tiktok_search_videos(query="NICHE_KEYWORD")

# Search with emotional angle keywords
mcp__dansugc__tiktok_search_videos(query="NICHE relatable")

# Instagram reels for different hook styles
mcp__dansugc__instagram_search_reels(query="NICHE_KEYWORD")
```

### 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" |

### 7c. Present Hook Ideas

For each hook, provide:

```markdown
### Hook [N]: "[The hook text]"

**Category:** [Hook type from table above]
**Inspired by:** [Video from search results with stats]
**Emotion:** [What UGC reaction to pair with — shocked, curious, crying, etc.]
**Text overlay format:**
  Line 1: [first line of text]
  Line 2: [second line, if needed]
**Matching caption:**
  [Full caption including hashtags]
```

### 7d. Hook Research Strategy

**To find hooks that match a specific format:**
1. Search for the format keyword (e.g., "supplement review TikTok")
2. Look at the top 10-20 results
3. Extract the first line of each caption — this is usually the hook
4. 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
2. Search for the product category + emotional keywords
3. 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: `claude mcp add --transport http -s user dansugc https://dansugc.com/api/mcp -H "Authorization: Bearer YOUR_KEY"`
- Restart Claude Code after adding

**Apostrophes breaking text overlays:**
- Use `textfile=/tmp/mytext.txt` instead of inline `text='...'`
- Write text to file first: `printf "don't stop" > /tmp/mytext.txt`

**Speed-up clips output wrong duration:**
- Always use two-pass: trim first with `-c copy`, then speed up with `setpts`
- Never combine `-ss`/`-to` with `setpts` in a single pass

**DanSUGC Posting returns 403 / subscription error:** User needs an active DanSUGC Posting subscription — go to dansugc.com/dashboard to subscribe.

**Post stuck in failed state:** Use `mcp__dansugc__list_posts()` to check error details, then `mcp__dansugc__delete_post(id=...)` and recreate.

**Text cut off by platform UI:**
- Check Green Zone specs in [./references/green-zone.md](./references/green-zone.md)
- Y must be between 210 and 1480, X between 60 and 960 (universal)
