Agent skills you can check before you install

From the author

Ten animated UI mockups for product, launch and dev-tool videos, rebuilt as HTML instead of screen recordings: phone message thread, team chat channel, coding-agent terminal session, terminal command run, desktop terminal window, desktop notification banner, code editor walkthrough, 3D code slab, exploded UI panels and an amber CRT console. Presets give typing speed (12-20 characters per second with seeded gaps), reading holds from character count, entrance easing and scale, camera lead before each action, text size as a share of frame height, and theme colors from MIT theme sources, from Charm VHS, Screen Studio, Emil Kowalski, Apple HIG and Netflix timing rules. Use when someone wants a fake text or Slack conversation, a terminal or Claude Code demo, a code walkthrough or an exploded UI shot in a video. NOT for recording a real screen or for real people's messages presented as genuine.
