Must be read before creating, relaying out, or repairing 3:4 vertical Oh My PPT pages. Defines poster-card layout, focal hierarchy, vertical section planning, evidence grouping, compact two-column pockets, chart/list budgeting, plus catalog and checklist references for 1200x1600 canvases.
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
# Vertical 3:4 Layout Skill This skill is the layout source of truth for `vertical-3-4` pages, usually 1200x1600. A 3:4 page is a vertical poster-card canvas. It has enough width for rich information cards and compact two-column pockets, but its reading path is still vertical. The layout should feel like a poster with one strong anchor and grouped evidence, not a long feed of equal blocks. **This canvas is a poster card, not a compressed slide.** When the source content is dense or "needs to be summarized", the model MUST summarize harder here, not cram the full outline into one page. A 3:4 poster that tries to hold a 16:9 deck's worth of content will overflow no matter how the fonts are tuned. Deep details live in the references: - `references/catalog.md` - named poster-card patterns and 1200x1600 zone skeletons. - `references/checklist.md` - P0/P1/P2 structural self-check for delivery. ## Preflight Before writing HTML, decide: 1. **Message** - the one sentence this card should make the viewer remember. 2. **Focal anchor** - title block, hero metric, chart, image/diagram, framework, or conclusion. …

How to install
mdr add sdcxb/codem/vertical-3-4-layout-skill@sha256:c76caa76406cc4a3The line at the top of this page pins the label git:20260831.2e0d311, which is what most people want. 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.
