Can I combine multiple animation effects?

Yes, the toolkit is designed with composable primitives. You can layer multiple effects, such as applying a 'shake' on impact at the end of a 'bounce' sequence.

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

The skill applies aggressive optimization strategies, including limiting frame counts to 10-15, reducing color palettes to 32-48 colors, and removing redundant pixel data to ensure strict compliance.

Does this require external image editing software?

No, the skill provides all necessary programmatic tools for drawing, text rendering, and frame manipulation directly through its Python-based toolkit.

How does the typography tool help with small emojis?

It includes a specialized rendering function that adds high-contrast outlines to text, ensuring readability even at the 128x128 resolution required for Slack emojis.
