How does it handle Slack's file size limits?

The skill includes optimization strategies like reducing the color palette (typically to 48 or 128 colors), lowering the FPS, and removing duplicate frames.

What are the recommended dimensions for Slack GIFs?

For custom emojis, 128x128 pixels is recommended. For GIFs intended for messages, 480x480 pixels is the standard target.

Can I use emoji fonts in the GIF creation?

The skill recommends against using emoji fonts as they are unreliable across platforms; it focuses on drawing custom vector-like shapes and text instead.

Can I create smooth animations like fades or bounces?

Yes, the skill includes specialized easing functions (ease_in, ease_out, bounce_out, etc.) and alpha blending utilities for professional-looking motion.

Does this skill require pre-made image assets?

No, it is designed to draw graphics from scratch using PIL primitives, though it can also manipulate images that you upload to the workspace.
