slack-gif-creator
Toolkit for creating animated GIFs optimized for Slack, with validators for size constraints and composable animation primitives. This skill applies when users request animated GIFs or emoji animations for Slack from descriptions like "make me a GIF for Slack of X doing Y".
Why this skill is useful
Adds executable scripts for GIF creation and validation tailored specifically for Slack's requirements, which the AI wouldn't generate on its own.

What this skill does
Slack GIF Creator - Flexible Toolkit A toolkit for creating animated GIFs optimized for Slack. Provides validators for Slack's constraints, composable animation primitives, and optional helper utilities. Apply these tools however needed to achieve the creative vision. Slack's Requirements Slack has specific requirements for GIFs based on their use: Message GIFs: Max size: ~2MB Optimal dimensions: 480x480 Typical FPS: 15-20 Color limit: 128-256 Duration: 2-5s Emoji GIFs: Max size: 64KB (strict limit) Optimal dimensions: 128x128 Typical FPS: 10-12 Color limit: 32-48 Duration: 1-2s Emoji GIFs are challenging - the 64KB limit is strict. Strategies that help: Limit to 10-15 frames total Use 32-48 colors maximum Keep designs simple Avoid gradients Validate file size frequently Toolkit Structure This skill provides three types of tools: 1. Validators - Check if a GIF meets Slack's requirements 2. Animation Primitives - Composable building blocks for motion (shake, bounce, move, kaleidoscope) 3. Helper Utilities - Optional functions for common needs (text, colors, effects) Complete creative freedom is available in how these tools are applied. Core Validators To ensure a GIF meets Slack's constraints, use these validators: File size validator: Dimension validator: Complete validation: Animation Primitives These are composable building blocks for motion. Apply these to any object in any combination: Shake Bounce Spin / Rotate Pulse / Heartbeat Fade Zoom Explode / Shatter Wiggle / Jiggle Slide Flip Morph / Transform Move Effect Kaleidoscope Effect To compose primitives freely, follow these patterns: Helper Utilities These are optional helpers for common needs. Use, modify, or replace these with custom implementations as needed. GIF Builder (Assembly & Optimization) Key features: Automatic color quantization Duplicate frame removal Size warnings for Slack limits Emoji mode (aggressive optimization) Text Rendering For small GIFs like emojis, text readability is challenging. …
