+description: Explain what the `design` plugin does and how to use it. Use when the user invokes `/design-usage`, asks what this plugin covers, or wants help choosing how to review or direct visual and copy work.
+---
+
+# Design Usage
+
+## How to respond
+
+- If the user invoked this skill without a concrete task, start by explaining what this plugin does and when it should be used.
+- If the user already gave a concrete design or copy task, briefly explain why this plugin fits, then load `deslopify` and do the work.
+- Do not reply with filler like "skill loaded", "ready for the task", or "what would you like to do?" before explaining the plugin.
+
+## What this plugin does
+
+- Gives art direction against the generic AI look: glow gradients, radius on autopilot, icon-in-circle, centred-everything, filled card rows, stock typefaces, generated-looking imagery.
+- Keeps a page consistent: one component set, one badge style, the brand palette, one type scale, no near-duplicate colours or text styles.
+- Covers responsive layout, accessibility, interface states and realistic content.
+- Lists the words and sentence shapes, in English and Polish, that make UI and marketing copy read as generated.
+- Works with any brand: the universal rules always apply, and a default Swiss/editorial direction is used only when the project has none.
+- Ends with a review checklist to run on desktop and mobile screenshots before shipping.
+
+## How to use it
+
+- Load it before designing or writing a section: a landing page, an artifact, a Figma frame, a UI mockup.
+- Ask it to review something that "looks AI-generated", generic or templated, and fix it.
+- Ask it to rewrite hero, FAQ or testimonial copy plainly.
+
+## Example requests
+
+- "Deslopify this hero section."
+- "This pricing page looks too SaaS. What exactly is wrong with it?"
+- "Rewrite these FAQ answers so they don't read like AI."
+
+## Reach for these assets
+
+- `deslopify` (`/design:deslopify`) - banned patterns, composition, type, colour and copy rules, and the pre-ship checklist.
