Are the GIFs compatible with other platforms?

While specifically optimized for Slack's dimensions and file constraints, the generated GIFs are standard files that will work on Discord, Microsoft Teams, or any web-based platform.

What kind of graphics can I animate?

You can animate standard emojis, custom shapes, text with readability outlines, and even complex particle systems or mirror effects using the provided helper utilities.

Can I combine multiple animation effects?

Yes, the animation primitives are designed to be composable. You can apply multiple transformations, such as a bounce and a shake, to the same object within your frame generation logic.

How does this skill handle Slack's 64KB emoji limit?

The skill includes specialized validators and an 'emoji mode' that applies aggressive optimization techniques, such as reducing the color palette to 32-48 colors and limiting frame counts to stay under the strict limit.

Does this require external image editing software?

No, this skill is designed to be entirely programmatic, utilizing Python-based tools like the PIL library to create, optimize, and save GIFs directly within your Claude Code environment.
