Douyin Reverse Engineer

从抖音视频反推AI绘画提示词和分镜脚本。当用户提到反推提示词、视频反推、抖音分析、分镜反推、游戏改写、视频转提示词时触发。

Security Scan

The skill generally matches its stated purpose (download a Douyin video and produce AI prompts via Volcengine ARK) but contains several implementation inconsistencies and it will upload user videos to a third party (Volcengine) using your ARK_API_KEY — review before installing or running.

Purpose & Capability

The name/description (reverse-engineer Douyin videos into AI prompts/storyboards) aligns with the code: it downloads videos and calls a video-analyzer that uses Volcengine ARK. Required environment variable ARK_API_KEY is appropriate for that. However, the code references a 'douyin-downloader' skill (skills/douyin-downloader/...) while the SKILL.md and _meta.json list dependencies only as doubao-video-analyzer and video-downloader — that mismatch (and minor path variations like 'script' vs 'scripts') is an incoherence that may cause runtime failures or indicate sloppy packaging.

Instruction Scope

The runtime instructions and code explicitly upload the user's video to Volcengine (parse_video.py does client.files.create and submits frames to an Ark model). That means user video content will be transmitted to a third-party service (Volcengine) under the provided ARK_API_KEY. The SKILL.md does call out ARK_API_KEY, but the code-level description and docstrings confirm the upload behavior — this is expected for the skill's function but carries privacy/third‑party exposure risk. Also the code invokes other local skill scripts (douyin-downloader, video-downloader, doubao-video-analyzer); SKILL.md instructs installing two of these but not the douyin-specific downloader the code imports.

Install Mechanism

There is no remote download/install spec in the package itself (no arbitrary URL downloads or extract operations). The skill is delivered as code plus SKILL.md and relies on other skills installed via 'npx clawhub install ...' (which is an expected, lower-risk install path).

Credentials

Only ARK_API_KEY is declared as a required env var and is the primary credential — that is consistent with a skill that calls Volcengine ARK. The SKILL.md also expects system tools (python, ffmpeg, yt-dlp) provided by other skills; those are plausible. Still, the ARK API key is sensitive because it authorizes uploading and processing of content — ensure you trust the endpoint and rotate/revoke the key if needed.

Persistence & Privilege

The skill is not 'always: true' and is user-invocable. It does not request persistent privileges or claim to modify other skills' configs. It runs as a user-invoked script and does not appear to self-enable or persist settings beyond normal file outputs.

What to consider before installing

Before installing or running this skill: (1) Be aware it will upload videos to Volcengine (ARK) using your ARK_API_KEY — do not use sensitive/proprietary video unless you accept that exposure. (2) The package's manifest and README do not fully match the code: the script imports a 'douyin-downloader' skill that is not listed in _meta.json or the SKILL.md install instructions — you may need to install that separately or the script will fail. (3) Review the other skills (doubao-video-analyzer, video-downloader, and any douyin downloader) that this skill calls; they will run network I/O and may require additional tools (yt-dlp, ffmpeg). (4) Consider testing with a non-sensitive local video first and run in a sandboxed environment; keep the ARK_API_KEY scoped/rotated and revoke it if you don't trust the service or after testing. (5) If you need higher assurance, request the missing/unclear packaging details from the author or inspect the other referenced skill code (douyin-downloader, doubao-video-analyzer) before use.

从抖音视频URL出发，自动完成：下载视频 → 豆包AI分析 → 反推AI绘画提示词 + 分镜脚本 → 游戏风格改写。

前置依赖

使用前请先安装以下 skill：

npx clawhub install doubao-video-analyzer
npx clawhub install video-downloader

同时需要配置环境变量：

• ARK_API_KEY：火山引擎 ARK API Key（用于豆包视频分析）

系统依赖：

• Python 3.8+
• ffmpeg（video-downloader 需要）
• yt-dlp（video-downloader 需要）

用法

# 完整流程（需要 ARK_API_KEY 环境变量）
python skills/douyin-reverse-engineer/reverse_video.py "抖音URL"

# 分析本地视频
python skills/douyin-reverse-engineer/reverse_video.py --local ./video.mp4

# 仅下载（不分析）
python skills/douyin-reverse-engineer/reverse_video.py "抖音URL" --download-only

# 自定义输出目录
python skills/douyin-reverse-engineer/reverse_video.py "URL" --output ./out

# 跳过游戏向改写
python skills/douyin-reverse-engineer/reverse_video.py "URL" --no-rewrite

# 启用锈湖（Rusty Lake）风格改写（调用 Seed-2.0-lite 大模型逐场景改写）
python skills/douyin-reverse-engineer/reverse_video.py "URL" --rusty-lake

依赖

• doubao-video-analyzer skill（volcenginesdkarkruntime + ARK_API_KEY）
• video-downloader skill（yt-dlp + ffmpeg）

注意：首次使用请先运行 npx clawhub install doubao-video-analyzer 和 npx clawhub install video-downloader 安装依赖 skill。
