Do I need any external design software to use this?

No, this skill uses programmatic Python libraries to generate frames from scratch, meaning you can create complex animations entirely through code and Claude.

Can I combine different animation effects?

Yes, the animation primitives are designed to be composable. You can layer multiple motions, such as applying a 'shake' effect on top of a 'bounce' trajectory for more dynamic visuals.

Does it support text overlays?

Yes, it includes typography utilities specifically designed for small GIFs, providing high-contrast outlines to ensure text remains readable at emoji scales.

How does this skill handle Slack's 64KB emoji limit?

The toolkit includes a specialized emoji mode that uses aggressive color quantization (32-48 colors) and frame-count reduction to ensure animations stay under the strict 64KB threshold.

Design Tools

Generates and optimizes animated GIFs and custom emojis specifically tailored for Slack's file size and dimension constraints.

This skill provides a comprehensive toolkit for developers to programmatically create, animate, and validate GIFs for Slack. It features a suite of animation primitives—including shake, bounce, and kaleidoscope effects—alongside strict validators that ensure assets meet Slack’s specific requirements for both message attachments and the challenging 64KB emoji limit. Whether you are building custom reaction emojis or automated status updates, this toolkit handles the complexities of color quantization and frame optimization to produce high-quality, lightweight visual assets directly through Claude.
