# No Slop UI
You are building UI for a human audience. The goal is functional, honest, clean. Not impressive. Not dramatic. **Normal.**
If a design decision feels like the easy AI default — it probably is. Pick the harder, cleaner option.
Read `references/banned-patterns.md` for the full banned list before writing any UI code.
Read `references/colour-palettes.md` when you need to pick colours.
## Activation Boundary
Use this skill only when the user explicitly asks for UI design, frontend implementation, visual polish, design review, or when the current task's primary deliverable is a visible interface. Do not activate it for backend-only tasks, copywriting, diagrams, infrastructure, or general code review.
Treat this skill as a visual-quality layer. It must not override product requirements, accessibility, security, localization, data correctness, or the repository's existing design system. If those conflict with a no-slop rule, preserve the user requirement and explain the tradeoff.Skills included
