How does the skill ensure GIFs are small enough for Slack?

The skill employs several optimization strategies including reducing the color palette (down to 48 colors), lowering the FPS (10-30 range), and removing duplicate frames during the save process.

What are the recommended dimensions for Slack emoji GIFs?

For optimal display as a Slack emoji, GIFs should be 128x128 pixels. For standard message attachments, 480x480 is recommended.

What types of animation effects are supported?

The skill supports a wide range of effects including shaking/vibration, pulsing/heartbeats, gravity-based bouncing, rotation, fading, sliding with overshoot, and particle explosions.

Can I use existing images as a base for animations?

Yes, you can upload existing images which the skill can then manipulate, split into frames, or use as visual reference for drawing new graphics.

デザインツール

Generates and optimizes high-quality animated GIFs specifically tailored for Slack emojis and message attachments using Python.

The Slack GIF Creator skill provides Claude with a specialized toolkit for building professional-grade animations directly from code. It combines PIL-based drawing primitives with advanced animation concepts like easing functions, motion blur, and particle bursts to create polished visual assets. Beyond creation, the skill includes specialized validation and optimization utilities that ensure GIFs meet Slack's technical requirements for file size, dimensions, and frame rates, making it an essential tool for developers looking to automate custom emoji or reaction GIF generation.
