stopmotion-video: before/after cuts that land on the beat
The author scrolls his skill page for 65 seconds: each example plays twice, once as an agent made it without the skill and once with it, against a metronome. Logos snap in pose by pose, counters tick up, typed titles and page changes all land on the beat.

What it does

stopmotion-video writes down how a designer cut a 47-second launch film to a drum and bass track, so an agent can do the same to a new song instead of copying the old video. The frame rate stays low on purpose: each…
Use stopmotion-video: measure the tempo of song.wav, then cut a 20-second Remotion film of our three new features, one page per bar, clicks on the snares, and end on a beat.

Step by step
Open the GitHub repo, or the author's skill page to see the before/after examples played against a metronome.
Install it with npx skills add kosta4a/stopmotion-video (or clone the repo and copy skills/stopmotion-video into ~/.claude/skills).
Give your agent a song you have the rights to and a short brief, e.g. use stopmotion-video to cut a 30-second launch film for our new search feature to this track.
Check the cut with the contact sheets and metronome it makes, give notes as timestamps, then render.
Watch out for
It brings no music, samples or fonts: use a track you are allowed to publish. The repo was published today and has only a handful of stars, and the author does not take issues or pull requests, so fork it if you need changes. It is a set of rules plus helpers, so results still depend on your agent and your review rounds.

teardown: any machine as a 3D simulator you can take apart
A Claude Code skill that answers "how does this work?" by building the machine as one offline 3D page: it runs in the middle, panels read its live numbers, buttons open the part doing the work, and one click blows it apart. It can also record a short tour video of it.
