What it does

In the author's own words, from each skill's SKILL.md.

  • halfsize

    Compress a video to an exact target size (20 MB, 16 MB, 700k, ...) on the local machine with FFmpeg, then verify quality with VMAF/SSIM. Use when a user needs a video to fit a platform cap, asks to "make this smaller", or wants to know what a size cut costs in quality.

Review before you install

A skill is a set of instructions and scripts your agent will follow, and it can run code on your machine. Read the SKILL.md and any scripts first — this listing is not a security review.
