What are the recommended dimensions for Slack emojis?

For Slack emoji GIFs, 128x128 pixels is the recommended standard to ensure clarity and platform compatibility.

How does this skill help with GIF file size limits?

The skill includes optimization strategies such as reducing the color palette to 48-128 colors, lowering the frame rate (FPS), and removing duplicate frames to keep files under Slack's upload limits.

Does this skill require external libraries?

Yes, it relies on the Pillow, imageio, and numpy Python packages to handle image manipulation and GIF encoding.

What kind of animation effects are available?

The skill supports a wide range of effects including shaking/vibrating, pulsing, bouncing, spinning, fading, and complex particle bursts using built-in easing functions.

Can I turn my own photos into Slack GIFs using this tool?

Yes, the skill can load user-uploaded images via PIL (Pillow) to apply animations, split them into frames, or use them as a reference for programmatic drawing.

コラボレーションツール

Generates and optimizes high-quality animated GIFs and custom emojis specifically tailored for Slack environments.

概要

The Slack GIF Creator is a specialized toolkit that allows Claude to programmatically design, animate, and optimize GIFs. It handles platform-specific constraints such as 128x128 dimensions for emojis and 480x480 for messages, while providing sophisticated utilities for fluid motion. With built-in easing functions, drawing primitives, and validation tools, it enables the creation of professional-grade animations—like pulsing hearts, shaking alerts, or particle bursts—from scratch or user-uploaded images while ensuring file sizes remain within Slack's limits.
