Slack-optimized GIFs must stay under specific size limits and dimensions. This Skill validates GIFs against Slack's constraints—64KB for emoji (128x128) and larger limits for message GIFs—and enforces frame rate and color budgets to ensure your animation uploads without compression or rejection.

Yes. This Skill provides reusable animation building blocks—shake, bounce, spin, and others—that you compose into frames. These primitives handle the easing and timing, letting you focus on describing what animation you need rather than coding frame sequences manually.

Slack emoji GIFs must be 128x128 pixels, under 64KB, and use a limited color palette. This Skill enforces those constraints by validating dimensions, file size, frame count, and color count before you export, so your emoji works in Slack conversations without errors.

Describe what you want—for example, 'rocket emoji doing a spin'—and this Skill maps that to animation primitives, applies Slack validators for size and dimensions, optimizes the color palette, and produces a ready-to-upload GIF in one step.

This Skill enforces Slack's functional requirements: limited color counts per frame to stay under size budgets, standard frame rates (typically 10 FPS for smooth playback), and duration constraints. The validators catch violations during composition so you don't upload oversized files.
