SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires pillow, imageio, imageio-ffmpeg, numpy, and includes scripts (resource) components.

What problem does it solve?

Manually creating GIFs that meet Slack's strict size and dimension requirements is time-consuming and frustrating. This skill automates the entire process, ensuring your GIFs are always optimized and ready to share.

Core Features & Use Cases

Slack-Optimized GIFs: Automatically resizes, quantizes colors, and removes duplicate frames to meet Slack's 2MB (message) or 64KB (emoji) limits.
Composable Animation Primitives: Build complex animations from simple blocks like shake, bounce, spin, fade, and zoom.
Use Case: Quickly turn a text description like "make me a GIF for Slack of a rocket emoji zooming across the screen and then exploding" into a perfectly formatted, shareable GIF.

Quick Start

Example: Create a simple pulsing emoji GIF

from core.gif_builder import GIFBuilder from templates.pulse import create_pulse_animation

builder = GIFBuilder(128, 128, 10) frames = create_pulse_animation( object_type='emoji', object_data={'emoji': '😱', 'size': 80}, num_frames=12, pulse_type='throb' ) builder.add_frames(frames) builder.save('reaction.gif', num_colors=40, optimize_for_emoji=True)
