How does it optimize GIFs for Slack emojis?

It implements specific color palette reduction (down to 48 colors), frame rate adjustments, and dimension scaling to 128x128 to meet Slack's strict file size limits for emojis.

Does this skill support pre-made emoji fonts?

No, to ensure cross-platform reliability, the skill focuses on drawing shapes and graphics from scratch using PIL primitives rather than relying on system-dependent emoji fonts.

What types of animation effects are available?

It supports a wide range of motion concepts including pulsing, bouncing, rotating, fading, sliding, and particle bursts, all powered by mathematical easing functions.

Can I use my own images with this skill?

Yes, the skill can load user-uploaded images using PIL to use them directly as frames, split them into components, or use them as a stylistic reference for new animations.

What are the recommended dimensions for Slack GIFs?

The skill follows Slack best practices by defaulting to 128x128 for emoji-style GIFs and 480x480 for larger message-style GIFs.

Design Tools

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

About

This skill empowers Claude to create polished, professional animated GIFs by providing a robust framework for frame generation, easing animations, and Slack-specific optimization. It includes specialized utilities for handling color palettes, file size constraints, and smooth motion curves, making it ideal for developers and teams looking to automate the creation of custom reactions, status icons, or informational animations directly within their Slack workspace. By utilizing PIL (Pillow) and advanced easing functions, it bridges the gap between basic graphic scripts and production-ready assets.
