Can I animate my own uploaded images?

Absolutely. The skill can load user-uploaded images using PIL to either animate them directly or use them as reference inspiration for new graphics.

How does the skill handle Slack's file size limits?

It provides optimization strategies such as reducing color palettes (typically to 48-128 colors), lowering FPS, and removing duplicate frames.

Does this skill require external design software?

No, all graphics are generated programmatically using the Pillow (PIL) library, allowing for fully automated GIF creation within the Claude environment.

Does it support custom easing and motion effects?

Yes, it includes a dedicated easing module supporting linear, ease-in, ease-out, bounce-out, and elastic motion for professional-grade animations.

What dimensions does this skill use for Slack GIFs?

The skill defaults to 128x128 for Slack emojis and 480x480 for message GIFs to ensure optimal display and performance.

Design Tools

Generates high-quality animated GIFs optimized for Slack emojis and messages using Python-based drawing and animation utilities.

About

The Slack GIF Creator skill equips Claude with the specialized knowledge and programmatic tools needed to build custom animations that adhere to Slack's strict technical requirements. It handles complex tasks like frame-rate optimization, palette reduction for file size management, and precise dimension scaling for both emojis and message attachments. By leveraging PIL primitives and advanced easing functions, the skill allows users to create professional-looking animations—ranging from simple pulsing icons to complex particle bursts—directly through code, ensuring every GIF is 'Slack-ready' upon export.
