# 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 thes

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".
How do I install it?
Run `npx skills add composio-community/awesome-codex-skills --skill slack-gif-creator --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From composio-community/awesome-codex-skills, a repository with 15,591 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
