+# UI Design Activation Checklist
+
+Use this checklist before generating any page, component, or visual interface.
+
+## Required checks
+
+1. Output the design specification first.
+2. Choose a concrete aesthetic direction rather than generic adjectives.
+3. Define a color palette and typography before writing markup or styles.
+4. Confirm the target platform: Web or mini program.
+5. Read the platform implementation skill after the design spec is fixed.
+
+## Common failure patterns
+
+- Starting with JSX, WXML, or CSS before design intent is stated.
+- Falling back to generic AI visual patterns.
+- Missing platform-specific layout or asset constraints.
+
+## Done criteria
+
+- The design spec is visible in the response.
+- Aesthetic direction, palette, and typography are explicit.
+- The next implementation skill is known before UI code starts.
