Slack GIF & Emoji Creator

About

Slack GIF Creator is a specialized toolkit designed to streamline the creation of animated assets for Slack workspace communication. It addresses the platform's challenging technical requirements—most notably the strict 64KB limit for custom emojis—by providing built-in validators and aggressive optimization algorithms. The skill features a rich library of composable animation primitives such as shakes, bounces, and morphs, allowing users to transform simple descriptions into complex animations. Whether you are creating a 480x480 message GIF or a perfectly compressed 128x128 reaction emoji, this tool ensures your creations are upload-ready without the need for external design software.
