name: design-screen description: Design or build a page, screen, landing page, website, app or UI from a request - the whole job, end to end. Use this for "design a landing page", "build a settings screen", "make me a website", "design the onboarding", "ออกแบบหน้าเว็บ", "ทำหน้า landing", "ออกแบบ UI", "ทำแอป". It runs the pipeline no single skill covers: the house doctrine, a written Brief Inference so the result is not the statistical mean, a committed visual direction, tokens, build, the objective gates, then an adversarial critic. Hands off to data-dashboard for dense data screens, redesign for existing UI, and image-to-code when a reference image is given.

Skill: Design a screen

Do this first, before anything else

Write the Brief Inference block into your reply now. Not after reading the rest of this file, not in your head, not "once the layout is clearer" - now, before any markup, any file, any tool call.

Domain:           fintech | editorial | dev-tool | healthcare | consumer | ...
Audience & tone:  expert vs first-time, calm vs energetic, premium vs utilitarian
Mood:             the one adjective the result must earn - "expensive", "precise", "warm", "brutal"
Motion depth:     none | subtle feedback | expressive choreography
Layout family:    the section sequence you will use, named, varied per section
Reference anchor: an archetype, or a named system - see step 3

Fill in every line with a decision. Mood: clean is not a decision; Mood: expensive is. If you cannot name the mood and the layout family, you have not decided anything yet and whatever you generate will regress to the mean.

The stop condition: if you are about to write markup, create a file, or call a tool that produces UI, and this block is not already in your reply, stop and write it first. Measured on 2026-10-07, one run in three skipped it - the skill loaded, the block did not get written, and the result was a screen designed by nobody. This section is at the top of the file because it was previously below twenty-nine lines of background, and background is not an instruction.

Everything below is how to execute the decisions above.

Is the kit here? This skill reads files from the kit. Check once: ls ${CLAUDE_SKILL_DIR}/../../../tokens >/dev/null 2>&1 && echo KIT_OK || echo KIT_MISSING On KIT_MISSING only the skill folders were installed, which is what npx skills add does. Say so plainly, point the user at npx ux-ui-agent-skills init or the plugin install, and stop. Do not guess the contents of a file you could not open.

Hand off instead, when the work is actually

| The request | Use | |---|---| | A dashboard, terminal, console, or any screen whose job is many numbers at once | data-dashboard | | An existing site or app to improve | redesign | | A screenshot, mockup or reference image to match | image-to-code | | One component's spec, not a screen | design-component | | A brand foundation from scratch, before any screen | brandkit |

Otherwise, continue.

1. Taste preflight

The block at the top of this file. If it is not in your reply yet, go back and write it before reading further - the rest of this skill executes decisions it assumes you have already made.

Full version and the reasoning: ${CLAUDE_SKILL_DIR}/../../../taste/design-taste.md.

Banned defaults — break each one deliberately

These are the tells that make UI read as generated. They are defects, not starting points.

• Three or four identical equal-weight cards. One thing leads: more size, more weight, or its own row. A grid of equals gives the eye nowhere to land.
• Everything centered. Use asymmetry and a real grid. Center sparingly.
• The same left-text / right-image row repeated. Vary composition per section.
• Display type that is just bold body text. The largest heading is at least 2.5x the body size, short, on a wide measure (18-24ch).
• Generic drop shadow on every box. Most things are flat; elevation is layered and rare.
• Pure #000 on #fff. Off-black on warm-white, from the theme.
• A rainbow of accents. One primary, one accent at most; neutrals carry it.
• Emoji anywhere - icons, bullets, status dots, labels. Use lucide inline SVG with currentColor, or plain words. This is a hard gate, not a preference.
• Em-dashes in UI copy, marketing filler ("elevate", "seamless", "unlock"), hollow triads ("powerful, intuitive, beautiful"), fake labels ("SECTION 01", lorem ipsum). Say the concrete thing or say nothing.
• A colored border on one side only of a card, alert, toast or callout. The tinted 3-4px strip is a generated-UI cliche. Full hairline border or surface separation, and status carried by a real icon plus text, never colour alone.
• Cramped vertical rhythm. Generous macro-whitespace between sections.

2. Doctrine

Load design-doctrine and follow it. The parts that decide this job: token by intent, one shared theme, the eight states on every interactive element, one thing leads, zero emoji, and never state a number you did not measure.

3. Direction into tokens

Pick the reference anchor from ${CLAUDE_SKILL_DIR}/../../../taste/aesthetic-systems.md or the library at ${CLAUDE_SKILL_DIR}/../../../design-systems/library/, then resolve it into tokens rather than styling screens directly. One CSS-variable layer, imported once. If a brand colour fails contrast, adjust it: taste serves tier 4 and never overrides accessibility.

Reference output to match for quality: ${CLAUDE_SKILL_DIR}/../../../examples/showcase/ and ${CLAUDE_SKILL_DIR}/../../../examples/templates/.

4. Build

Mobile is the base, not an afterthought: write the phone layout as the base styles and layer wider screens on with min-width. max-width is fine for a narrow refinement, never as the way mobile gets supported. Every value a token. Every interactive element ships all eight states. Content first, then the layout that serves it.

5. Gate — run it, never claim it

node ${CLAUDE_SKILL_DIR}/../../../scripts/accuracy_report.mjs

Report the real N/N line. For a single file, at minimum:

node ${CLAUDE_SKILL_DIR}/../../../scripts/verify_states.mjs <file> [--dark]
node ${CLAUDE_SKILL_DIR}/../../../scripts/verify_responsive.mjs <file> --scale=1.25
node ${CLAUDE_SKILL_DIR}/../../../scripts/slop_tells.mjs --strict <file>
node ${CLAUDE_SKILL_DIR}/../../../scripts/taste_audit.mjs --strict <file>

A render gate with no browser prints SKIPPED and exits 0. That is not a pass. Set DS_REQUIRE_BROWSER=1 when you run one on its own and intend to trust it.

6. Render and look

Gates pass while a screen is still visibly broken. Screenshot it, look at every state, and click each control to confirm something actually changed.

7. Critic

Run /critique. It is adversarial on purpose and it sees the work, not your reasoning. A passing gate is never evidence of taste.

What you deliver

The Brief Inference block, the files, the real gate output, and the critic's verdict. If a gate was not run, say which and why - an unmeasured result is reported as unmeasured, never as a pass.
