Does it support text in GIFs?

Absolutely. It includes typography helpers specifically designed for small dimensions, featuring text outlines and high-contrast scaling to ensure words remain readable at emoji sizes.

How does this skill handle Slack's 64KB emoji limit?

The skill uses aggressive optimization strategies including limiting color palettes (32-48 colors), reducing frame counts (10-15 frames), and automatic color quantization to ensure emojis stay under the strict 64KB threshold.

Can I combine multiple animation effects?

Yes, the animation primitives are composable. You can apply multiple movements like 'bounce' and 'shake' to the same object or sequence them to create complex animations.

What kind of objects can I animate?

You can animate standard emojis, geometric shapes (circles, rectangles), or custom images. The toolkit provides wrappers for various object types to apply motion consistently.
