Are the GIF dimensions automatically adjusted?

The skill includes dimension validators that check against Slack's optimal sizes (128x128 for emojis and 480x480 for messages) to prevent unwanted scaling or cropping after upload.

Does it support text in GIFs?

Yes, it includes a typography helper that renders text with outlines to ensure readability even on small, low-resolution emoji GIFs where standard text might become blurry.

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

The skill uses specialized validators and aggressive optimization strategies, such as limiting frame counts and color palettes (typically 32-48 colors), to ensure animations remain within Slack's strict upload limits.

Can I combine different animation effects?

Yes, the toolkit is designed with composable primitives. You can layer multiple effects, such as applying a 'shake' on top of a 'bounce' movement, to create complex and unique custom animations.
