What types of animations can I build with this toolkit?

It includes a wide range of primitives like shake, bounce, spin, heartbeat pulse, explosion, zoom, slide, flip, and kaleidoscope effects that can be composed together.

Can I add readable text to my Slack emojis?

Yes, the toolkit includes specialized typography helpers that render text with customizable outlines, which is essential for readability at the small 128x128 emoji scale.

How does this skill handle the 64KB Slack emoji limit?

The skill applies aggressive optimization strategies such as limiting frame counts (10-15 frames), reducing color palettes to 32-48 colors, and providing a real-time size validator to ensure compliance.

Does this require external GIF optimization software?

No, the skill uses its own internal GIFBuilder and validators to handle quantization and duplicate frame removal directly within the workflow.

About

The Slack GIF Creator is a specialized toolkit designed to help developers and designers build Slack-compatible animations directly through Claude. It addresses the technical hurdles of Slack's platform, particularly the strict 64KB limit for custom emojis, by providing automated validators, intelligent color quantization, and a library of composable motion primitives. From simple 'party' effects to complex message-bound GIFs, this skill ensures your creative output meets Slack's 128x128 or 480x480 requirements without the need for external optimization tools.
