Anything longer than a few seconds, or video with audio — this is a chat-format tool
What it is
An official skill that produces short animated GIFs at chat-appropriate sizes and frame budgets. It is a small tool with a clear scope: generate frames, assemble, check dimensions and weight. The constraint that matters is file size — a GIF that takes three seconds to load is worse than no GIF.
Install
Clone the repository, then copy the skill folder into your agent's skills directory — ~/.claude/skills/ for Claude Code. Skills are plain files: no build step, no daemon.

Read the SKILL.md before you install. A good skill states when it applies, what it must not do, and how to verify the result. A skill that only lists adjectives will change the agent's tone without improving its output — skip those.
