Does it support smooth animations like bouncing or fading?

Yes, it includes a dedicated easing module (core.easing) that supports linear, ease-in/out, bounce, elastic, and back-out motion profiles for professional-looking movement.

What are the recommended dimensions for Slack emojis?

The skill follows Slack's best practices, recommending 128x128 pixels for emojis and 480x480 pixels for message-embedded GIFs.

Can I use existing images or do I have to draw everything from scratch?

You can do both. The skill supports loading user-uploaded images via PIL for direct animation or using them as visual inspiration for programmatically drawn graphics.

How does this skill handle Slack's strict file size limits?

The skill includes built-in optimization strategies such as reducing the color palette to 48-128 colors, lowering FPS, and removing duplicate frames to ensure GIFs fit within Slack's constraints.
