What kind of animation effects can I generate?

The skill supports a wide range of effects including shaking, pulsing, bouncing, rotating, fading, sliding, zooming, and particle-based explosions.

Does this skill support Slack's specific emoji size limits?

Yes, it includes pre-configured settings for 128x128 dimensions and specific color palette optimization to ensure GIFs stay under Slack's file size limits.

How does it optimize GIFs for file size?

It implements several strategies including reducing color depth to 48-128 colors, lowering the FPS, and removing duplicate frames during the save process.

Can I use my own images to create GIFs with this skill?

Absolutely. You can upload existing images to use as direct frames, split them into components, or use them as a reference for colors and style.

设计工具

Generates and optimizes custom animated GIFs specifically tailored for Slack emojis and message requirements.

关于

The Slack GIF Creator skill provides a comprehensive toolkit for building high-quality, lightweight animations within the Claude Code environment. It combines domain-specific knowledge of Slack's technical constraints—such as 128x128 dimensions and specific color indexing—with advanced utilities for easing, frame composition, and file size optimization. Developers can create complex animations from scratch using PIL primitives or manipulate uploaded images to produce professional-grade reactions, status icons, and expressive visuals that meet Slack's strict performance standards.

主要功能

Seamless integration with PIL for custom graphic drawing and image manipulation
Advanced animation primitives for shakes, pulses, spins, and explosions
Automated GIF optimization via color reduction and duplicate frame removal
Built-in Slack requirement validation for dimensions and file size
2 GitHub stars
Sophisticated easing functions including bounce, elastic, and ease-out

使用场景

Generating expressive message reactions that exceed the quality of standard emoji sets
Creating animated status indicators and progress bars for team updates
Designing custom branded Slack emojis from vector shapes or text
