What dimensions are supported for Slack GIFs?

The skill is optimized for Slack's standard requirements: 128x128 pixels for emojis and 480x480 pixels for message-embedded GIFs.

How does the skill handle animation motion?

It provides a variety of easing functions (like bounce, ease-out, and elastic) to create smooth, professional-grade motion instead of basic linear movements.

Does this skill guarantee the GIF will upload to Slack?

Yes, it includes built-in validation tools that check dimensions, duration (recommended under 3 seconds), and file size to ensure the output is Slack-ready.

How can I reduce the file size for large animations?

The skill offers multiple optimization strategies, including reducing the color palette (e.g., to 48 colors), lowering the FPS, and removing duplicate frames during the save process.

Can I use my own images as a starting point?

Absolutely. The skill can use the PIL library to load user-uploaded images, allowing you to animate them directly or use them as a reference for styling.
