Slack Gif Creator

If you're creating reaction GIFs or memes for Slack, you know the pain of hitting the file size limit. This skill gives you animation primitives and validators specifically tuned for Slack's constraints, so you can programmatically generate GIFs that actually upload instead of manually compressing them in some online tool. It's from Anthropic's official skills repo, which means the primitives are designed to compose well when Claude builds animations for you. Useful when you need custom animated content that fits Slack's requirements without the trial and error of exporting, checking size, adjusting quality, repeat.
