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

The toolkit uses aggressive optimization strategies, including limiting color palettes to 32-48 colors, reducing frame counts, and using duplicate frame removal to ensure emojis stay under the strict 64KB threshold.

Does it support text rendering for small emojis?

Yes, the skill includes a specialized typography helper that adds outlines to text, ensuring it remains readable even at the 128x128 resolution required for Slack emojis.

What kind of motion effects are included?

The toolkit includes a wide range of primitives such as shake, bounce, spin, pulse, fade, zoom, explode, wiggle, slide, flip, morph, and kaleidoscope effects.

Can I combine multiple animation effects?

Yes, all animation primitives are composable. You can layer effects like 'bounce' and 'shake' or 'spin' and 'fade' on a single object to create complex custom motions.

Generates Slack-optimized animated GIFs and emojis with built-in size validation and composable motion primitives.

关于

This skill provides a comprehensive toolkit for building high-quality animated GIFs tailored specifically for Slack's unique technical constraints. It streamlines the creation of both large message-based GIFs and ultra-lightweight custom emojis, which are notoriously difficult to keep under the 64KB limit. By offering a library of composable motion primitives—such as shakes, bounces, and kaleidoscope effects—alongside automated validators for file size and dimensions, it ensures that your creative assets are both visually engaging and guaranteed to upload successfully to Slack.
