text2video tasks-get (round-robin)

python3 {baseDir}/scripts/happyhorse-magic.py text2video-get --task-id "\x3CTASK_ID_FROM_VIDEO_GEN>"

Image to Video Generation (happyhorse-1.0-i2v)

Generate video from a first-frame image. Output aspect ratio automatically follows the input image.

First-frame to Video

python3 {baseDir}/scripts/happyhorse-magic.py image2video-gen --first-frame "https://example.com/landscape.jpg" --resolution "1080P" --duration 10
python3 {baseDir}/scripts/happyhorse-magic.py image2video-gen --prompt "花朵缓缓绽放" --first-frame "https://example.com/flower.png" --duration 8 --no-watermark

Options

  • --prompt: Text prompt for video generation (optional but recommended)
  • --first-frame: First frame image URL (required). Format: JPEG/JPG/PNG/WEBP, min 300px per side, max 10MB.

  • --duration: Video duration in seconds, 3-15 (default: 5)
  • --no-watermark: Disable "Happy Horse" watermark (default: enabled)
  • --seed: Random seed for reproducibility [0, 2147483647]

Note: There is no --ratio parameter. The output video aspect ratio automatically follows the input first-frame image.

image2video tasks-get (round-robin)

python3 {baseDir}/scripts/happyhorse-magic.py image2video-get --task-id "\x3CTASK_ID_FROM_VIDEO_GEN>"

Reference to Video Generation (happyhorse-1.0-r2v)

Generate video from reference images as character/object sources. Use "character1", "character2", etc. in the prompt to reference images by their array order.

Multi-character Reference

python3 {baseDir}/scripts/happyhorse-magic.py reference2video-gen --prompt "身着红色旗袍的女性character1，镜头以侧面中景勾勒旗袍修身剪裁" --reference-images "https://example.com/girl.jpg" --resolution "720P" --ratio "16:9" --duration 5
python3 {baseDir}/scripts/happyhorse-magic.py reference2video-gen --prompt "身着红色旗袍的女性character1，轻抬玉手展开折扇character2时流苏耳坠character3随头部转动轻盈摆动" --reference-images "https://example.com/girl.jpg" "https://example.com/fan.jpg" "https://example.com/earrings.jpg" --resolution "720P" --ratio "16:9" --duration 5

Options

  • --prompt: Text prompt with character references (required, max 5000 non-Chinese chars). Use "character1/character2/..." to reference images in array order.
  • --reference-images: Reference image URLs (required, 1-9 images). The 1st image = character1, 2nd = character2, etc.
  • --resolution: Video resolution - 720P or 1080P (default: 1080P)
  • --ratio: Aspect ratio - 16:9, 9:16, 1:1, 4:3, 3:4 (default: 16:9)
  • --duration: Video duration in seconds, 3-15 (default: 5)
  • --no-watermark: Disable "Happy Horse" watermark (default: enabled)
  • --seed: Random seed for reproducibility [0, 2147483647]

Note: Reference images should have short side >= 400px. Avoid low-resolution, blurry, or heavily compressed images.

reference2video tasks-get (round-robin)

python3 {baseDir}/scripts/happyhorse-magic.py reference2video-get --task-id "\x3CTASK_ID_FROM_VIDEO_GEN>"

Video Editing (happyhorse-1.0-video-edit)

Edit existing videos with text instructions and optional reference images. Supports style transfer, local replacement, and other editing tasks.

Options

  • --prompt: Editing instruction (required, max 5000 non-Chinese chars)
  • --video: Input video URL to edit (required, mp4/mov, 3-60s input, output max 15s)
  • --reference-images: Reference image URLs for editing (optional, 0-5 images)
  • --resolution: Output resolution - 720P or 1080P (default: 1080P)

安全使用建议
This skill appears to do what it claims: it calls DashScope (HappyHorse) APIs and requires a DASHSCOPE_API_KEY. Before installing: 1) Only provide a DashScope API key you trust and that has limited scope; avoid using high-privilege or long-lived keys. 2) Be careful with local-file arguments: the included script will base64-embed and send local files to the external service, so do not point it at sensitive files (SSH keys, credentials, private documents). 3) Ensure the runtime environment has python3 and a safe requests installation (the script assumes the requests package). 4) If you enable autonomous agent invocation, consider limiting autonomy or auditing requests and outputs — autonomous agents could be instructed to upload arbitrary local files. 5) If you need higher assurance, validate the API endpoints and behavior by running the script in an isolated environment (container/VM) and inspect network traffic or server-side logs.
功能分析
Type: OpenClaw Skill Name: happyhorse-video-gen-edit Version: 1.0.0 The skill provides a legitimate interface for Alibaba's DashScope HappyHorse video generation and editing models. The primary script, scripts/happyhorse-magic.py, implements standard API interactions with https://dashscope.aliyuncs.com, including support for local file uploads via base64 encoding and task status polling. No evidence of malicious intent, data exfiltration to unauthorized domains, or prompt injection was found.

能力评估
✓ Purpose & Capability
Name/description, referenced endpoints (dashscope.aliyuncs.com), and required environment variable (DASHSCOPE_API_KEY) align with the HappyHorse / DashScope AIGC video service; python3 requirement is expected for the provided script.
ℹ Instruction Scope
Runtime instructions tell the agent to run the included Python script which performs HTTP requests to dashscope.aliyuncs.com. The script will accept URLs or local file paths and will base64-embed local files (data: URIs) into the request body — this is necessary to upload local media but means arbitrary local files can be read and transmitted if the user or agent supplies those paths. The SKILL.md does not attempt to read unrelated system config or credentials.
✓ Install Mechanism
There is no install spec (instruction-only with an included script). Nothing is downloaded from unknown URLs and no installers run; the only runtime dependency is python3 (the script also uses the requests library, which is not installed by the skill).
✓ Credentials
Only one environment variable is required: DASHSCOPE_API_KEY (declared as primaryEnv) which is appropriate for authenticating to the DashScope API. No unrelated credentials or config paths are requested.
✓ Persistence & Privilege
The skill is not forced-always-enabled and does not request elevated or cross-skill config changes. Note: autonomous invocation is allowed by default (platform default) — combined with the ability to upload local files, this increases the practical blast radius if the agent is granted broad autonomy.
