iart motion skills: pick the pack, brief the motion, check the export

iart open-sourced 54 animation skills in 17 installable packs that teach your coding agent to make motion graphics, data charts and short videos. You install one pack into the agent you already use, describe the motion you want in concrete terms, and the skill tells the agent to render the video and inspect its own frames. What you need: a coding agent such as Claude Code, Cursor or Codex, Node.js for the installer, and the renderer your pack uses. The skills are free under MIT; any paid generation service stays paid.
