slack-gif-creator skillA

slack-gif-creator is agent-read markdown (skill) from davepoon/buildwithclaude: Toolkit for creating animated GIFs optimized for Slack, with validators for size constraints and composable animation primitives. This skill applies when users request animated GIFs or emoji animations for Slack from descriptions like "make me a GIF for Slack of X doing Y"..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add davepoon/buildwithclaude/slack-gif-creator@git:20260104.903b22f
Exact content
mdr add davepoon/buildwithclaude/slack-gif-creator@sha256:4bdf07d22b49f56c

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
