## From README

Slack GIF Creator A toolkit providing utilities and knowledge for creating animated GIFs optimized for Slack. Slack Requirements Dimensions: Emoji GIFs: 128x128 (recommended) Message GIFs: 480x480 Parameters: FPS: 10-30 (lower is smaller file size) Colors: 48-128 (fewer = smaller file size) Duration: Keep under 3 seconds for emoji GIFs Core Workflow Drawing Graphics Working with User-Uploaded Images If a user uploads an image, consider whether they want to: Use it directly (e.g., "animate this", "split this into frames") Use it as inspiration (e.g., "make something like this") Load and work with images using PIL: Drawing from Scratch When drawing graphics from scratch, use PIL ImageDraw primitives: Don't use: Emoji fonts (unreliable across platforms) or assume pre-packaged graphics exist in this skill. Making Graphics Look Good Graphics should look polished and creative, not basic. Here's how: Use thicker lines - Always set width=2 or higher for outlines and lines.
