Seedance Video Generation
Generate AI videos via SkillBoss API Hub's unified video generation capability.
Prerequisites
The user must set the SKILLBOSS_API_KEY environment variable. You can set it by running:
export SKILLBOSS_API_KEY="your-api-key-here"
Base URL: https://api.skillbossai.com/v1/pilot
Supported Models
SkillBoss API Hub automatically routes to the optimal video generation model. Model hints are passed via the inputs field and honored when available.

Execution (Recommended: Python CLI Tool)
A Python CLI tool is provided at ~/.claude/skills/seedance-video/seedance.py for robust execution with proper error handling and local image base64 conversion. Prefer using this tool over raw curl commands.
Quick Examples with Python CLI
# Text-to-video (create + download)
python3 ~/.claude/skills/seedance-video/seedance.py create --prompt "小猫对着镜头打哈欠" --download ~/Desktop
# Image-to-video from local file
python3 ~/.claude/skills/seedance-video/seedance.py create --prompt "人物缓缓转头微笑" --image /path/to/photo.jpg --download ~/Desktop
# Image-to-video from URL
python3 ~/.claude/skills/seedance-video/seedance.py create --prompt "风景画面缓缓推进" --image "https://example.com/image.jpg" --download ~/Desktop
# First + last frame
python3 ~/.claude/skills/seedance-video/seedance.py create --prompt "花朵从含苞到盛开" --image first.jpg --last-frame last.jpg --download ~/Desktop
# Reference images (Lite I2V)
python3 ~/.claude/skills/seedance-video/seedance.py create --prompt "[图1]的人物在跳舞" --ref-images ref1.jpg ref2.jpg --model doubao-seedance-1-0-lite-i2v-250219 --download ~/Desktop
# Custom parameters
python3 ~/.claude/skills/seedance-video/seedance.py create --prompt "城市夜景延时摄影" --ratio 21:9 --duration 8 --resolution 1080p --generate-audio false --download ~/Desktop
# Draft mode (cheaper preview)
python3 ~/.claude/skills/seedance-video/seedance.py create --prompt "海浪拍打沙滩" --draft true --download ~/Desktop
# Generate final video from draft
python3 ~/.claude/skills/seedance-video/seedance.py create --draft-task-id <DRAFT_TASK_ID> --resolution 720p --download ~/Desktop

Rules
- Always check that
SKILLBOSS_API_KEY is set before making API calls: [ -z "$SKILLBOSS_API_KEY" ] && echo "Error: SKILLBOSS_API_KEY not set" && exit 1
- Default to Seedance 1.5 Pro hint (
doubao-seedance-1-5-pro-251215) unless user requests a specific model.
- Default to 720p, 16:9, 5 seconds, with audio for text-to-video.
- Default to adaptive ratio for image-to-video (auto-adapts to the input image).
- Video URLs expire in 24 hours - always download immediately after generation.
- For local image files, convert to base64 data URL format before sending.
- Always show the user the video URL so they can access the result.
- When generation fails, display the error message clearly and suggest possible fixes.
