Does it support text in GIFs?

Yes, it includes a typography helper that renders text with outlines to ensure maximum readability even at the small scales required for Slack emojis.

Can I combine different animation styles?

Yes, the toolkit is designed with composable primitives. You can layer multiple effects, such as applying a 'shake' animation to an object while it is performing a 'bounce' or 'move' sequence.

What dimensions are used for Slack GIFs?

The tool defaults to 128x128 for emojis and 480x480 for message GIFs, adhering to Slack's optimal viewing standards while managing file size.

How does it handle the 64KB Slack emoji limit?

The skill uses aggressive optimization strategies, including limiting color palettes to 32-48 colors, reducing frame counts to 10-15, and removing duplicate frames to ensure strict 64KB compliance.
