What animation effects are available?

It provides a wide range of building blocks including shake, bounce, spin, pulse, fade, zoom, explode, wiggle, slide, flip, and morphing effects.

Are the animation primitives composable?

Absolutely. You can layer multiple effects, such as applying a bounce motion and a shake effect simultaneously to the same object for high-impact animations.

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

The toolkit includes an 'optimize_for_emoji' mode that applies aggressive color quantization (32-48 colors) and limits frame counts to ensure files meet the strict 64KB requirement.

Does it validate dimensions automatically?

Yes, it includes built-in validators to check both file size and pixel dimensions against Slack's recommended standards for messages and emojis.

Can I render text on my GIFs?

Yes, the skill includes specialized typography helpers that add outlines to text, making it readable even at the small 128x128 dimensions required for Slack emojis.

Acerca de

The Slack GIF Creator skill provides a comprehensive toolkit for developers using Claude to programmatically generate animated assets tailored for Slack workspaces. It features specialized validators to ensure GIFs meet Slack’s specific message (~2MB) and emoji (64KB) constraints, which are notoriously difficult to hit manually. With a rich library of composable animation primitives—including shaking, bouncing, morphing, and kaleidoscope effects—it enables the rapid creation of high-quality, lightweight animations from simple descriptions, ensuring your custom reactions and announcements look professional and upload without errors.
