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

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

Can I combine multiple animation effects like bounce and shake?

Yes, the toolkit is designed with composable primitives. You can apply multiple transformations—such as a bounce combined with a shake on impact—to any object within a single GIF.

Does it support text rendering for small emojis?

Yes, it includes specialized typography helpers that add outlines and use specific scaling to ensure text remains legible even at the 128x128 resolution used by Slack emojis.

Do I need external design software like Photoshop to use this?

No, this skill provides programmatic drawing, text rendering, and motion tools directly within the Claude Code environment, allowing for purely code-driven asset creation.
