Douyin Dedup

抖音视频下载、去水印、深度混剪去重、去除音频的全自动处理工具。当用户发送抖音链接（v.douyin.com 或 douyin.com 格式）并要求处理、去重、下载或类似意图时，自动触发此技能。

Security Scan

The skill's code and runtime instructions are consistent with its stated purpose (downloading and transforming Douyin videos); it requires local ffmpeg/yt-dlp/Python and writes output to ~/video-dedup, and it does not request credentials or contact unexpected remote endpoints.

Purpose & Capability

The skill name/description (Douyin download + dedup) matches the included script behavior: network download from Douyin/iesdouyin/aweme endpoints, use of yt-dlp fallback, and ffmpeg-based processing. Minor inconsistency: registry metadata lists no required binaries, but the SKILL.md and script clearly require ffmpeg, ffprobe, yt-dlp and Python3.

Instruction Scope

SKILL.md instructs the agent to run the included script from the skill's scripts directory. The script only reads the provided Douyin URL, fetches video content from Douyin-related hosts, runs ffmpeg/ffprobe/yt-dlp, and writes files under ~/video-dedup; it does not attempt to read other system files, environment secrets, or send data to third‑party endpoints beyond video hosts.

Install Mechanism

No install spec is present and the skill is instruction+script only. That is low-risk as nothing is downloaded during install. The script invokes system binaries (ffmpeg, yt-dlp), so those must be installed separately by the user.

Credentials

The skill requests no environment variables or credentials. Its network access is limited to fetching video pages and media URLs derived from the provided Douyin link; no secrets or unrelated service tokens are requested.

Persistence & Privilege

always:false and user-invocable:true (normal). The skill writes output to its own workspace/output directories in the user's home and does not modify other skills or system-wide agent settings.

Assessment

This skill appears to do what it says: it downloads Douyin videos (via Douyin/iesdouyin/aweme endpoints or yt-dlp), removes audio/watermark and runs ffmpeg transforms, then saves files under ~/video-dedup. Before installing or running: 1) Ensure you have trusted ffmpeg, ffprobe and yt-dlp binaries installed (the registry metadata did not declare these, but the script needs them). 2) Be aware it will download media from the internet and write files to your home directory — run in a sandbox/container if you want isolation. 3) This tool can be used to repurpose others' content (legal/terms-of-service risk); verify you have rights to process videos. 4) If you need higher assurance, review the full script (dedup.py) locally and run it manually once rather than granting broad automation. No credentials are requested and I found no hidden remote endpoints or exfiltration logic.
