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".
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 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) …

How to install
mdr add frankxai/agentic-creator-os/slack-gif-creator@sha256:e5ce81d3dc40e778The line at the top of this page pins the label git:20260124.0bc6f23, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
