Are there pre-built templates for common Slack reactions?

Yes, the skill includes 'excited wiggle', 'heartbeat pulse', 'explosion zoom', and 'jello wobble' templates frequently used in Slack culture.

How does this skill handle Slack's strict emoji size limits?

The skill includes a specialized 'emoji mode' that applies aggressive color quantization, limits frame counts to 10-15, and reduces the color palette to 32-48 colors to stay under the 64KB limit.

What kind of visual objects can I animate?

You can animate standard emojis, custom shapes, and text. The typography helper specifically adds outlines to text to ensure it remains readable at Slack's smaller display sizes.

Does this skill provide real-time validation?

It provides programmatic validators that check file size, dimensions, and FPS against Slack's specific requirements before you finalize the GIF.

Can I combine different animation effects?

Yes, the toolkit uses composable primitives, allowing you to layer multiple effects like 'shake', 'bounce', and 'fade' onto a single object for complex animations.
