Video Frames

Extract frames or short clips from videos using ffmpeg.

Security Scan

The skill does what it claims: an instruction-only helper that calls ffmpeg to extract frames; its files and instructions are coherent and proportional to that purpose.

Purpose & Capability

Name/description match the included script and instructions. The only dependency required is ffmpeg, which is appropriate for extracting frames; no unrelated binaries, env vars, or config paths are requested.

Instruction Scope

SKILL.md tells the agent to run the included scripts/frame.sh with a video path, optional time/index, and an output path. The script only checks the provided input file, creates the output directory, runs ffmpeg to write a single frame, and echoes the output path—there are no network calls, no reading of unrelated files or env vars, and no external endpoints referenced.

Install Mechanism

The registry lists no install spec (instruction-only), so nothing is written to disk beyond the included script when the skill is installed. SKILL.md metadata has a harmless suggestion to install ffmpeg via brew (ffmpeg is a well-known project); there are no downloads from untrusted URLs or extract steps.

Credentials

No environment variables, credentials, or config paths are required. The script does not read or depend on any secrets—requested privileges are minimal and proportional to the task.

Persistence & Privilege

Skill is not always-on and does not request elevated or persistent privileges. It does not modify other skills or system-wide agent settings; autonomous invocation is allowed (platform default) but not combined with other concerning flags.

Assessment

This skill is small and coherent: it runs the included frame.sh which calls your local ffmpeg to extract a frame. Before installing, ensure you have a trusted ffmpeg binary (install via your package manager if needed). The script only reads the video file you provide and writes the output you specify; it does not exfiltrate data or access other files. As with any tool that processes untrusted media, consider potential bugs in ffmpeg itself—avoid running it on untrusted files in high-security environments.

Video Frames (ffmpeg)

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.
