medium confidence
The skill is internally coherent for generating videos via the Doubao/Volcengine API and contains only expected network and file operations, but has a small coding bug and a few minor documentation inconsistencies you should be aware of before use.
评估建议
This skill appears to do what it says (generate videos via Volcengine/Doubao) and contains only the expected network and file operations, but check a few things before installing or running it: - Fix the BASE_URL bug: open scripts/generate_video.py and change the BASE_URL line from os.environ.get("VIDEO_GEN_API_KEY", ...) to os.environ.get("VIDEO_GEN_BASE_URL", "https://ark.cn-beijing.volces.com/api/v3"). Without that edit the intended VIDEO_GEN_BASE_URL env var will be ignored. - Provide only ...

用途与能力
Name/description match the included script and documentation: the skill calls a Doubao/Volcengine video-generation API and implements text/image/audio→video flows. Required capabilities (API key, optional base URL) are consistent with that purpose.
指令范围
SKILL.md instructs the agent to run scripts/generate_video.py and optionally upload a generated video to Feishu. The Feishu upload is presented as an example and would require separate Feishu app credentials (app_id/app_secret) which are not declared as required env vars; the script itself only performs video generation and download. The script will read any local file paths you pass (first-frame/reference-image) and upload them to the remote generation API as provided — be cautious about supplying sensitive local files.
安装机制
No install spec — instruction-only with included Python script. This is low-risk; nothing in the skill downloads or installs code at runtime beyond normal Python execution. The script depends on httpx but installation steps are left to the environment.
凭证需求
The docs declare VIDEO_GEN_API_KEY and VIDEO_GEN_BASE_URL, but the script contains a bug: BASE_URL is read using os.environ.get("VIDEO_GEN_API_KEY", default) instead of os.environ.get("VIDEO_GEN_BASE_URL", default). This is a coding mistake (not a secret-exfiltration pattern) but means the declared base-URL env var is ignored unless you modify the script. Aside from that, only the service API key is required; no unrelated credentials are requested by the code. The Feishu example requires app_id/app_secret, but those are not listed as required env vars — they're optional examples.
持久化与权限
The skill does not request persistent or elevated platform privileges (always: false, no special config paths, does not modify other skills). It performs network calls to the declared API endpoint and saves downloaded video files to disk, which is expected for its purpose.
安全有层次,运行前请审查代码。

技能文档

通过火山引擎 Doubao Seedance API 生成视频。

环境变量

脚本通过以下环境变量获取 API 配置:

  • VIDEO_GEN_API_KEY — 火山引擎 API Key
  • VIDEO_GEN_BASE_URL — API 基础地址(默认:https://ark.cn-beijing.volces.com/api/v3)

支持的生成模式

模式说明参数
text_to_video文生视频prompt
image_to_video图+文生视频(URL)prompt + --first-frame URL
image_to_video_base64图生视频(Base64)prompt + --first-frame 路径/base64

可用模型

  • doubao-seedance-1.5 — 完整版(默认)
  • seedance-lite — 轻量版

使用方法

文生视频

export VIDEO_GEN_API_KEY="your-api-key"

python3 scripts/generate_video.py "一只可爱的小猫在草地上奔跑,阳光明媚,慢动作" \ --mode text_to_video \ --output cat_running.mp4

图生视频

python3 scripts/generate_video.py "让图片中的人物转头微笑" \
  --mode image_to_video \
  --first-frame "https://example.com/image.jpg" \
  --output person_smile.mp4

图生视频(Base64)

python3 scripts/generate_video.py "让图片动起来" \
  --mode image_to_video_base64 \
  --first-frame ./input_image.png \
  --output animated.mp4

有声视频(首帧)

python3 scripts/generate_video.py "人物开口说话,声音洪亮" \
  --mode audio_video_first_frame \
  --first-frame ./portrait.jpg \
  --audio \
  --output talking.mp4

有声视频(首尾帧)

python3 scripts/generate_video.py "人物从左转头到右" \
  --mode audio_video_first_last_frame \
  --first-frame ./left.jpg \
  --last-frame ./right.jpg \
  --audio \
  --output turn_head.mp4

Seedance-Lite 参考图

python3 scripts/generate_video.py "参考图片风格生成视频" \
  --mode seedance_lite_reference \
  --reference-image ./style_ref.jpg \
  --output styled_video.mp4

工作流程

  • 理解需求:分析用户的视频需求,确定生成模式
  • 选择模式:文生视频、图生视频、有声视频等
  • 优化提示词:将用户描述扩展为详细的视频描述
  • 执行脚本:调用 scripts/generate_video.py 生成视频
  • 等待完成:视频生成通常需要几分钟
  • 上传视频:上传到飞书获取 file_key
  • 发送视频:使用 message 工具发送视频

飞书视频上传

import requests

# 获取 token(使用飞书 app_id 和 app_secret) resp = requests.post( "https://open.feishu.cn/open-apis/auth/v3/tenant_access_token/internal", json={"app_id": "YOUR_APP_ID", "app_secret": "YOUR_APP_SECRET"} ) token = resp.json()["tenant_access_token"]

# 上传视频 with open("video.mp4", "rb") as f: resp = requests.post( "https://open.feishu.cn/open-apis/im/v1/files", headers={"Authorization": f"Bearer {token}"}, files={"file": ("video.mp4", f, "video/mp4")}, data={"file_type": "mp4"} ) file_key = resp.json()["data"]["file_key"]

# 发送视频 # 使用 message 工具: {"file_key": ""}

提示词技巧

  • 描述动作:清晰描述主体运动、镜头运动
  • 时间感:快/慢动作、延时、瞬间
  • 氛围感:光线、天气、情绪
  • 镜头语言:推/拉/摇/移、特写/远景
