slack-gif-creator

slack-gif-creator is a catalogue entry in the Open Design collection, curated from Anthropic's official skills repository. It advertises a skill that creates animated GIFs optimized for Slack, including validators for Slack's size constraints and composable animation primitives. The card exists so a planning agent can discover the capability, not to ship the implementation itself.

As a discovery pointer, the entry is minimal. It provides trigger phrases ("slack gif", "animated gif", "reaction gif", "tiny gif") and explains that to run the full upstream workflow with its original assets, scripts, and references, you install the upstream bundle into your active agent's skills directory. The documented usage is to inspect the upstream README for exact paths, then invoke the skill by name or via one of the trigger phrases. The actual GIF-generation logic, size validators, and animation primitives live upstream at the Anthropic skills repository rather than in this card.

It is aimed at developers and Slack users who want to produce small, reaction-style animated GIFs that meet Slack's upload and display constraints. Because this is a thin catalogue listing rather than a full skill, users should consult the upstream source (github.com/anthropics/skills) for the real assets and capabilities.
