What it is
This skill helps you create polished, animated GIFs that work perfectly in Slack. Whether you need a custom emoji, a reaction GIF, or a fun animation for your team chat, it handles the sizing, optimization, and visual polish. You describe what you want, and the AI creates it — no design software or animation experience needed.
What it does
- Creates animated GIFs sized correctly for Slack (128x128 for emoji, 480x480 for messages)
- Generates smooth animations like bounces, spins, pulses, fades, and particle bursts
- Optimizes file size and color palettes so GIFs upload and display properly
- Validates GIFs against Slack's requirements and ensures they'll work
- Builds custom graphics from scratch or animates images you provide
Use it when
- You need a custom emoji for your team's Slack workspace
- You want a fun reaction GIF that's perfectly sized for Slack messages
- You're creating branded or inside-joke animations for your company chat
- You have an idea for an animation but no design tools or skills to make it
