Not pinned. Installing fetches whatever the repository holds at the time you run the command.

No human has reviewed this code. The checks below are a static scan of the files at one commit — nobody has run this skill or judged whether it works. A skill runs with whatever access you give your agent, so read the source before you install it.

Automated safety checks

scanned

This skill failed 2 of 6 checks. A failure is not proof of bad intent; it means something in the code needs a human to look at it before you run it.

  • No undeclared network calls: failed

    Contacts 1 host that is neither well-known infrastructure nor declared in the skill's frontmatter: astral.sh.

    Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.

About this skill

What it does

This skill provides access to a command-line tool for manipulating videos. It allows users to perform actions like trimming, resizing, and converting video files directly from within an AI agent workflow. The tool streamlines common video editing tasks, automating processes that would otherwise require manual intervention.

When to use it

  • Creating short clips: Automatically generate highlight reels or promotional snippets from longer videos.
  • Resizing videos for social media: Quickly adapt videos to fit specific platform requirements (e.g., Instagram Reels, TikTok).
  • Converting video formats: Change a video's format for compatibility with different devices or software.
  • Automating video processing pipelines: Integrate video editing steps into larger automated workflows.

Key capabilities

  • Video trimming
  • Video resizing
  • Video format conversion
  • Command-line interface

Example prompts

  • "Trim the video 'my_video.mp4' to the first 30 seconds."
  • "Resize 'presentation.mov' to a resolution of 1280x720 and save it as 'presentation_resized.mp4'."
  • "Convert 'footage.avi' to an MP4 format."

Tips & gotchas

The skill requires the underlying video-tool CLI to be installed on the system where the AI agent is running. Ensure that the necessary dependencies are met before attempting to use this skill.
