Do I need external design software like Photoshop?

No, this skill allows you to programmatically generate and preview animations directly within your Claude Code environment using the included Python-based animation engine.

Can I combine different animation effects?

Yes, the animation primitives are fully composable. You can apply multiple effects, such as a bounce and a shake, to the same object simultaneously using the provided interpolation functions.

What formats does the creator support?

It outputs standardized .gif files that are pre-validated against Slack's specific requirements for both standard message attachments and custom emoji uploads.

How does it handle Slack's 64KB emoji limit?

The skill uses aggressive optimization strategies, including color quantization to 32-48 colors, frame count reduction (10-15 frames), and automatic duplicate frame removal to meet the strict limit.

Does the toolkit support text rendering?

Absolutely. It includes a typography helper that renders text with customizable outlines to ensure high readability even at small emoji resolutions (128x128).
