Can I combine multiple animation effects?

Yes, the animation primitives are fully composable. You can layer multiple effects, such as applying a 'shake' on impact at the end of a 'bounce' sequence.

Do I need external design software like Photoshop?

No, this skill provides programmatic tools to generate frames, render text with outlines, and apply visual effects directly using Python-based helper utilities.

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

It uses aggressive color quantization (limiting to 32-48 colors), reduces frame counts to 10-15, and utilizes a dedicated emoji optimization mode in the GIF builder to ensure compliance.

What are the recommended dimensions for Slack GIFs?

For standard message GIFs, the skill defaults to 480x480 pixels. For custom emojis, it optimizes for 128x128 pixels to ensure clarity at small scales.
