This does exactly what you'd expect: helps Claude generate animated GIFs that actually work in Slack. It wraps PIL with constraints for Slack's dimensions (128x128 for emoji, 480x480 for messages), provides easing functions for smooth motion instead of janky linear interpolation, and includes validators so you know before uploading whether your GIF will get rejected. The documentation is unusually thorough on making things look polished rather than programmer art, with specific guidance on line weights, layering shapes, and combining animation concepts like bounce plus rotation. If you're building Slack bots or custom emoji and tired of hand-tweaking GIFs in Photoshop, this gives Claude the guardrails to do it programmatically.
