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

It employs aggressive optimization strategies such as reducing color palettes to 32-48 colors, limiting frame counts to 10-15, and using specialized 'emoji mode' save functions.

Can I combine multiple animation effects?

Yes, the animation primitives are designed to be composable. You can layer effects like 'bounce' and 'shake' within a single frame generation loop to create complex motions.

Does it support custom text in the GIFs?

Yes, it includes a typography module with helpers to add outlines and specific scaling to ensure text remains readable at small emoji resolutions.

Are there built-in templates for common animations?

The toolkit includes several pre-built templates for common motions like loading spinners, heartbeats, explosions, and sliding transitions.

设计工具

Generates optimized animated GIFs and custom emojis for Slack using programmable animation primitives and size-constraint validators.

The Slack GIF Creator is a specialized toolkit designed to help developers and AI agents build Slack-compatible animations programmatically. It addresses the technical challenges of Slack’s strict file size limits—specifically the 64KB constraint for emojis—by providing automated validators, aggressive color optimization, and frame-management utilities. With a library of composable animation primitives like shakes, bounces, and morphs, users can transform simple descriptions into production-ready visual assets that meet exact dimension and FPS requirements.
