slack-gif-creator

Slack-optimized GIFs are automatically validated and resized to fit Slack's constraints: up to 2MB for message GIFs and 64KB for emoji GIFs. This Skill enforces these limits during generation, ensuring your animations deploy without rejection or manual optimization.

A composable toolkit of animation primitives includes shake, bounce, spin, pulse, fade, zoom, explode, wiggle, slide, flip, morph, move, and kaleidoscope effects. Combine these to create dynamic animations from descriptive text prompts, then apply them to emoji or message GIFs.

Yes. Build custom emoji GIFs by describing what you want—for example, a bouncing celebration emoji—and the Skill generates a 64KB-compliant animation ready to upload as a Slack reaction. Color quantization and frame deduplication optimize quality within the strict emoji size constraint.

The Skill depends on Pillow for image manipulation, ImageIO and ImageIO-FFmpeg for frame handling, and NumPy for numerical operations. These dependencies power color management, frame composition, and the modular GIF builder pipeline that produces Slack-ready animations.

No. Describe what animation you want in plain language—for example, "make me a GIF for Slack of confetti falling"—and the Skill generates it. You don't need to manually handle file size validation, color quantization, or Slack constraint enforcement; the Skill manages all of that.

The Skill validates GIF dimensions and file size before output, applying color quantization and frame deduplication to stay within Slack's constraints. If an animation cannot fit within limits without degradation, validation flags it so you can adjust parameters or simplify the animation.
