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

It employs aggressive optimization strategies including color quantization (limiting to 32-48 colors), frame reduction (10-15 frames), and real-time size validation to ensure the file fits.

Can I combine multiple animation effects?

Yes, the toolkit uses composable primitives, allowing you to layer effects like bounce and shake using interpolation and easing functions for complex motion.

What is the benefit of using this over a standard GIF editor?

It automates the tedious 'trial and error' process of meeting Slack's specific size constraints while providing programmatic, reproducible control over animations directly via AI commands.

What types of objects can I animate?

You can animate standard emojis, custom text with outlines, geometric shapes, or uploaded image frames using the provided helper utilities.

Does it support transparent backgrounds?

Yes, the GIF builder and validators are designed to support and maintain transparency, which is essential for Slack reaction emojis.
