The skill does what it says — it wraps ffmpeg to extract frames and requires only ffmpeg (installable via brew); there are no mysterious env vars, network calls, or extra permissions requested.
评估建议
This skill is straightforward: it runs a small bash wrapper around ffmpeg to extract frames and will install ffmpeg via Homebrew if needed. Before installing: ensure you are comfortable allowing brew to install ffmpeg; use the official ffmpeg package source; and be aware that processing untrusted video files can be risky because vulnerabilities have existed in ffmpeg in the past — consider running on trusted inputs or in a sandbox if the videos come from unknown sources. No credentials are reque...
详细分析 ▾
✓ 用途与能力
Name/description match the included files and runtime instructions. The only runtime dependency is ffmpeg (declared) and the script operates on a user-supplied video file to produce a local output image.
✓ 指令范围
SKILL.md and scripts/frame.sh only read the provided input video and write the specified output path. No reading of unrelated files, no network endpoints, no collection or transmission of extra data, and no vague 'gather whatever context you need' instructions.
✓ 安装机制
Install is limited to a homebrew formula (ffmpeg) which is a standard, well-known package source; no arbitrary downloads or archive extraction are used.
✓ 凭证需求
No environment variables, credentials, or config paths are required. The requested resources are proportional to the stated purpose.
✓ 持久化与权限
Skill is not always-enabled and does not request persistent system-wide changes or access to other skills' configurations. Default autonomous invocation is unchanged (normal).

技能文档

Extract a single frame from a video, or create quick thumbnails for inspection.

Quick start

First frame:

{baseDir}/scripts/frame.sh /path/to/video.mp4 --out /tmp/frame.jpg

At a timestamp:

{baseDir}/scripts/frame.sh /path/to/video.mp4 --time 00:00:10 --out /tmp/frame-10s.jpg

Notes

  • Prefer --time for “what is happening around here?”.
  • Use a .jpg for quick share; use .png for crisp UI frames.
