Slack GIF Creator

Slack GIF Creator is a narrow, specific skill: build a short animated GIF — a reaction, a celebratory loop, a simple animated icon — that’s actually sized and encoded correctly for Slack, which has its own quirks around file size, frame rate, and looping that a generic “make a GIF” attempt often gets wrong.

It handles the full loop from concept to encoded file: simple procedural animation (not video generation), frame timing, and export settings tuned for how Slack actually renders uploaded GIFs, so the output looks right the first time instead of needing a re-encode.

Small in scope, but the kind of skill that’s genuinely faster than doing it by hand once you need more than one of these — and a good example of how narrow a well-triggering skill is allowed to be.
