Slack GIF Creator is a skill in Anthropic's skills repository for making animated GIFs that meet Slack's limits. Its SKILL.md gives the sizes (128 by 128 for emoji, 480 by 480 for messages), a frame rate of 10 to 30, 48 to 128 colours and a duration under three seconds for emoji. The agent draws frames with Python's PIL library and saves them through a bundled GIF builder that can optimise for emoji, and a requirements file lists the dependencies. We would suggest it for teams who want custom emoji or reaction GIFs without a design tool. The limit is that the animation is drawn from shapes in code, so it suits simple loops, not footage or detailed art, and it needs Python. The folder holds an Apache 2.0 LICENSE.txt, the install line we list is the marketplace command for the whole repository, and the repository was last pushed on 6 November 2026, as read on 11 November. We have not run it ourselves.
