Does this skill handle Slack's file size limits automatically?

Yes, it includes optimization strategies such as reducing color palettes to 48-128 colors and removing duplicate frames to ensure GIFs meet Slack's constraints.

Does it support complex animations like easing and bouncing?

Yes, the skill includes a dedicated easing module providing linear, ease-in, ease-out, bounce, and elastic motion functions for fluid animations.

What are the recommended dimensions for Slack emojis?

For emoji GIFs, the skill defaults to 128x128 pixels as recommended by Slack, while message GIFs are scaled to 480x480 pixels.

Can I use my own images to create GIFs?

Absolutely. You can upload an image and the skill can use it either as a direct asset for animation or as a visual reference for colors and style.
