Banner-ad / display-creative generator with standard-size presets: Google Display (leaderboard, medium rectangle, mobile, skyscraper), LinkedIn, OG image, Twitter card, Facebook ad, header. Text-heavy ad aesthetic, ideogram-3-quality default. Use when: 'banner ad', 'display ad', 'OG image', 'Twitter card', 'баннер для рекламы', 'OG-картинка'.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
<objective> Banner-ad generator. Input: headline + CTA + optional subhead + brand + style. Output: N preset-sized banners (Google Display + social platforms). Distinct from `flyer-maker`: - Smaller aspect ratios (mostly horizontal, often extreme like 728×90 or 1456×180) - Dense text + CTA conventions (ad copy, not editorial) - Per-preset standard sizes (no custom aspects in v1) - "Ad feel" aesthetic — direct, conversion-focused, brand-loud Distinct from `cover-maker` / `thumbnail-maker`: - No artist / author / title-as-subject - Standard ad-platform sizes (presets, not "medium") - Includes explicit CTA element - Very small visual zones in some presets (300×250 has ~80% text) This skill does NOT: - Generate animated banners (HTML5 / GIF) — static PNGs only - A/B test variants for click-through — generate options, you measure - Place actual brand logo file in pixel-perfect position — model approximates; for exact placement use a vector design tool - Match exact platform ad-creative spec (file size, character limits) — that's downstream QA </objective> ## ROLE …

This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
