Does it support smooth motion transitions?

Yes, it includes a variety of easing functions like ease_in, ease_out, bounce_out, and elastic_out to avoid robotic-looking linear movement.

What are the recommended dimensions for Slack GIFs?

For custom emojis, 128x128 pixels is recommended. For larger message GIFs, 480x480 pixels is the standard target.

What animation effects are supported?

The skill includes logic for shaking, pulsing, bouncing, rotating, fading, sliding, zooming, and creating particle explosion effects.

How does this skill handle large GIF file sizes?

It provides optimization strategies including reducing the color palette to 48-128 colors, lowering the FPS (10-30), and removing duplicate frames during the save process.

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

You can do both. The skill can load existing images using PIL for direct animation or use them as a reference for colors and style while drawing new graphics.

设计工具

Generates and optimizes animated GIFs specifically tailored for Slack emojis and message reactions using Python utilities.

This skill equips Claude with specialized knowledge and Python-based tools to create professional-quality animated GIFs that meet Slack's unique technical requirements. It includes a dedicated GIFBuilder for frame assembly, easing functions for smooth motion, and built-in validation to ensure animations work perfectly as Slack emojis (128x128) or message reactions (480x480). By leveraging PIL primitives and advanced animation concepts like pulsing, shaking, and particle bursts, it allows developers to programmatically generate lightweight, visually polished assets that are automatically optimized for small file sizes.
