ad-platform-safe-zones skillA

ad-platform-safe-zones is agent-read markdown (skill) from popjam-io/skills: Current (2025–26, source-verified) safe-zone and canvas specs for ad creatives on Meta (FB/IG Feed, Stories, Reels), TikTok, and Google (Demand Gen, Responsive Display, Gmail), plus a bundled validator that checks finished images and renders overlay proofs. Use this whenever you generate, compose, resize, audit, or export ANY ad or social media creative — story/reels ads, feed images, banners, thumbnails, 9:16 / 4:5 / 1:1 / 1.91:1 canvases — even if the user never says "safe zone": platform UI c.

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 popjam-io/skills/ad-platform-safe-zones@git:20260811.9e2f405

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.
