Curated by Skill Harbor — the fourth sub-skill of the nextlevelbuilder ui-ux-pro-max-skill repo: a multi-format banner design system for social media, ads, website heroes, creative assets, and print — gathering requirements (purpose, platform, content, brand, style, quantity), proposing 2–3 art directions, building each banner in HTML/CSS at exact platform dimensions with safe-zone rules (critical content in the central 70–80%), then exporting to PNG via browser screenshot. Bundled reference of banner sizes and styles for Facebook, X, LinkedIn, YouTube, Instagram, Google Display, heroes, and print. Distinct from the three already-listed sub-skills of the same repo: ui-ux-pro-max (offline design-intelligence database), design (generative logo/CIP/banner identity via Gemini), and design-system (three-layer tokens and specs) — this one is the banner-craft skill. By @nextlevelbuilder, listed here with credit to its creator. Honest caveats: it designs banners only — no video editing, full website design, or print production; PNG export needs a browser/screenshot capability in the runtime; it applies your brand rules — it doesn't invent them. Skill Harbor never reviews the code, review it yourself before use.

Install
Prerequisites: none beyond a working agent; a browser/screenshot capability in the runtime for PNG export Install "Banner Design" for me. Design multi-format banners in HTML/CSS with exact platform sizes and safe zones Repository: https://github.com/nextlevelbuilder/ui-ux-pro-max-skill/blob/main/.claude/skills/banner-design/SKILL.md 1. Fetch the SKILL.md file for the nextlevelbuilder-banner-design skill from the repository into a temporary folder and summarize what it does in one or two sentences. 2. Safety check: review the SKILL.md and scripts for anything suspicious (unexpected network calls, shell commands, credential harvesting). This repo should contain zero secrets in code, credentials only via the secure vault, allowed hosts declared in the SKILL.md. Verify that holds here; STOP on any red flag and tell me. 3. Install it as a skill: copy SKILL.md and its helper files into the agent's skills directory, in a folder named "nextlevelbuilder-banner-design". 4. Verify with no network calls: frontmatter valid, files in place. 5. Report what was installed, where, and what I still need to do myself (e.g. any accounts, API keys, or CLI tools mentioned in the prerequisites above). GitHub is optional: if I have a GitHub account or the gh CLI, you may use it; otherwise public access is fine. Never require it unless it's in the prerequisites above. Rules: don't touch anything outside the temp folder and the install target. Never ask me to paste secrets in chat — credentials go through the secure vault or environment variables. If anything looks off, stop and ask me.
Questions
How do I install a build?
Every product page includes a copy-paste install prompt. Paste it into your Muse and it sets the build up for you — no manual configuration.
Where does my money go?
Straight to the seller. Skill Harbor never processes payments: checkout happens on the seller’s own page, usually Stripe.
What does the ✓ next to a creator’s name mean?
It means we confirmed the identity of the person behind the listing. It says nothing about the code itself — always check a build before installing it.
