What This Skill Does
Create animated GIFs optimized for Slack's display constraints. Provides size limits, validation tools, and animation concepts for creating GIFs that render well in Slack.
When to Use It
- Creating animated GIFs specifically for Slack
- Need to know Slack's GIF constraints (size, dimensions, frame count)
- Validating a GIF will display correctly in Slack
Slack Constraints
- Maximum file size for smooth playback
- Recommended dimensions for different Slack contexts (message, thread, channel header)
- Frame rate and frame count considerations
Best Practices
- Optimize for small file size — Slack compresses aggressively
- Keep animations short and looping
- Test in Slack before sharing widely
- Use appropriate dimensions for the target context
