Can I combine different animation effects?

Yes, the animation primitives are designed to be composable. You can layer effects like a bounce motion with a shake impact or a fade-in with a spin rotation.

Can I use my own custom emojis as the base for animations?

Absolutely. The toolkit allows you to specify emoji characters or custom object data as the source for any of the animation primitives provided.

How does this skill handle Slack's strict 64KB limit for emojis?

The skill includes an 'optimize_for_emoji' mode that applies aggressive color quantization (reducing palettes to 32-48 colors) and limits frame counts to ensure the final output fits within the 64KB threshold.

Does this skill require external image editing software?

No, the toolkit programmatically renders frames, text, and effects using Python-based builders, allowing you to generate complete GIFs entirely through code.

Generates and optimizes animated GIFs and custom emojis specifically tailored for Slack's file size and dimension constraints.

Slack GIF Creator is a specialized toolkit designed to streamline the creation of animated assets for Slack environments. It bridges the gap between creative vision and technical limitations by providing composable animation primitives—such as shakes, bounces, and morphs—alongside strict validators that ensure your creations meet Slack's 64KB limit for emojis or 2MB limit for message GIFs. With built-in support for color quantization, frame optimization, and specialized text rendering, this skill enables users to programmatically build high-quality, lightweight animations that work perfectly in any Slack workspace.
