How does the skill ensure GIFs are small enough for Slack?

The skill employs several optimization strategies including reducing the color palette (down to 48 colors), lowering the FPS (10-30 range), and removing duplicate frames during the save process.

What are the recommended dimensions for Slack emoji GIFs?

For optimal display as a Slack emoji, GIFs should be 128x128 pixels. For standard message attachments, 480x480 is recommended.

What types of animation effects are supported?

The skill supports a wide range of effects including shaking/vibration, pulsing/heartbeats, gravity-based bouncing, rotation, fading, sliding with overshoot, and particle explosions.

Can I use existing images as a base for animations?

Yes, you can upload existing images which the skill can then manipulate, split into frames, or use as visual reference for drawing new graphics.
