What is it?

A fun one. Claude knows Slack's size and file limits for message GIFs and custom emoji, and this skill gives it a small animation toolkit plus a checker so what it makes actually uploads and loops cleanly.

Without it, Claude's GIFs come out too big or the wrong shape. With it, you get a usable file first time, which is all a celebration emoji needs.

Install in Claude Code

In Claude Code run /plugin marketplace add anthropics/skills, then /plugin install example-skills@anthropic-agent-skills. That bundle includes this skill alongside Anthropic's other example skills.
