What kind of animation effects are supported?

It includes a wide variety of composable primitives such as shake, bounce, spin, pulse, zoom, explode, wiggle, slide, flip, morph, and even complex kaleidoscope effects.

Can I add readable text to tiny emojis?

Yes, the toolkit includes a typography module specifically designed to render text with high-contrast outlines, ensuring words remain legible even at 128x128 resolution.

How does it handle Slack's strict 64KB emoji limit?

The skill employs aggressive optimization strategies including limiting palettes to 32-48 colors, reducing frame counts to 10-15 frames, and using a specialized GIFBuilder that warns you immediately if limits are exceeded.

Does this skill work for standard message GIFs too?

Absolutely. While it excels at the difficult task of emoji optimization, it also includes presets and validators for standard 480x480 Slack message GIFs with a 2MB limit.

Collaboration Tools

Generates and optimizes animated GIFs and custom emojis specifically tailored for Slack's unique file size and dimension constraints.

The Slack GIF Creator is a specialized toolkit designed to streamline the production of Slack-compatible animations directly within your workflow. It provides a suite of composable animation primitives—such as shakes, bounces, and morphs—alongside strict validation tools to ensure exports meet Slack's rigorous 64KB limit for emojis and 2MB limit for message GIFs. Whether you are building an 'excited wiggle' emoji or a complex 'explosion zoom' reaction, this skill handles the technical overhead of quantization, frame optimization, and color management so you can focus on the creative vision.
