What it does

UI Score is an agent skill from sickn33/agentic-awesome-skills. Score a UI file's design quality 0-100 against StyleSeed's design language — per-category breakdown, the worst offenders, and a prioritized fix list. A quantified version of /ss-review.

Its SKILL.md is about 1.8k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Testing & QA, covering Design review and critique. The repository describes itself as: AAS Core is the local, agent-first control plane for complete catalog discovery, agent-owned selection, stack validation, and planning, backed by 2,400+ agentic skills. Includes… The licence is MIT.

When your agent uses it

  • Tasks that involve Design review and critique

Example prompts

  • “s design quality 0-100 against StyleSeed”
  • “/ui-score”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Score the just-generated UI.
  2. If < 80, apply the "fix first" list (use /ss-review to make the edits), then re-score.
  3. Repeat up to ~3×, or until ≥ 80.
  4. Present the UI with the final score and a one-line "fixed: …".

What it can do on your machine

Read from SKILL.md and the folder at commit ec02547. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

UI Score loads about 1.8k tokens when it runs. Until then it costs about 49 tokens; SKILL.md has 846 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~49
When it runs · the whole SKILL.md, loaded when a task matches
~1.8k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Design Score

When to Use

Use this skill when you need score a UI file's design quality 0-100 against StyleSeed's design language — per-category breakdown, the worst offenders, and a prioritized fix list. A quantified version of /ss-review.

/ss-review tells you what's wrong. /ss-score tells you how good it is overall and what to fix first — a single number plus a category breakdown, so you can track UI quality like you track test coverage.

When NOT to use

  • For a quick pass/fail before committing → use /ss-lint
  • For a full prose audit with fixes → use /ss-review
  • For non-UI files (logic, config) — scoring is meaningless

What to score

Score the file (or each file in a directory) on six weighted categories that map to the design language. Total = 100.

CategoryWeightReads from
Color discipline18DESIGN-LANGUAGE §1, §18, §72 + VISUAL-CRAFT §C4
Hierarchy & typography18§2, §3, §4, §16 + Font Size table + VISUAL-CRAFT §C2
Layout & rhythm14§13, §14, §15, §61 + VISUAL-CRAFT §C1
Cards & elevation12§7, §8, §12, §1 + VISUAL-CRAFT §C3

Motion & interaction8§24, §59 + engine/motion
Coherence12VISUAL-CRAFT §C0 (one choice per axis)

How to score each category

For each category, start at full marks and subtract for violations you find by reading the code. Be specific and evidence-based — cite the line.

Color discipline (20) — deduct for: any #000/text-black (−4 each, cap −8); more than one accent hue used decoratively (−5); emoji used as UI icons (multi-color, breaks single accent) (−5); a normal/OK/"보통" state shown in a status color instead of neutral grey (−4); status color on most/every row (no severity hierarchy) (−4); decorative hues (gold stars, rainbow category dots) instead of accent/grey (−3); hardcoded hex where a semantic token exists (−2 each, cap −6); status conveyed by color alone (−4).

Hierarchy & typography (20) — deduct for: number/unit not ~2:1 (−4); font sizes off the Font Size table / text-[var(--…)] for size (−5); everything the same weight, no clear primary (−5); cramped or wrong line-height on body (−3).

Layout & rhythm (15) — deduct for: content on bare background, not in cards (−6); px-4/px-8/mx-4 instead of px-6/mx-6 (−3); same section type repeated in a row (−4); no space-y-6 rhythm (−3).

Cards & elevation (15) — deduct for: 1px borders doing separation work that tone+shadow should (−4); shadows over ~8% opacity / visibly heavy (−4); no card/background tone separation (−5).

States & a11y (20) — deduct for: missing empty/loading/error state on a data surface (−5 each, cap −10); contrast below 4.5:1 body / 3:1 large (−6); touch target < 44px (−4); no visible focus / outline:none (−5); icon-only control without aria-label (−3).

Motion & interaction (8) — deduct for: random/ad-hoc fades instead of a named seed/keyword (−3); motion that delays content or blocks an action (−4); no prefers-reduced-motion handling on custom motion (−3); scroll-linked/parallax (forbidden, §59) (−5).

Coherence (12) — the "one choice per axis" laws (VISUAL-CRAFT §C0). Deduct for each axis that is mixed rather than unified across the file: mixed radius personalities, e.g. sharp panel + pill buttons (−5); two+ competing accent hues used for emphasis (−4); mixed shadow languages / light directions (−3); mixed icon families, fill modes, or stroke weights (−3); same radius on a nested element instead of inner = outer − padding (−2); inconsistent control heights for buttons/inputs (−2). This is the category that most predicts "looks AI-generated" — weight evidence of system-wide consistency, not per-component prettiness.

Clamp each category at 0. Sum to a total.

## Design Score: 70 / 100   (src/app/Dashboard.tsx)

████████████████░░░░░░  C-

Color discipline      13/18   ▓▓▓░  #000 headings (l.12,40); orange+blue+green accents (l.28-34)
Hierarchy & typography 15/18  ▓▓▓▓  number/unit 1:1 on hero (l.18)
Layout & rhythm        11/14  ▓▓▓░  two identical KPI rows (l.22-31)

Coherence               6/12  ▓▓░░  sharp cards (l.22) + pill buttons (l.48); 3 accent hues (§C0)

### Fix first (highest score gain)
1. Add empty + loading states to the orders list       → +7 states (§71)
2. Unify radius (pick soft 8-12px) + collapse to one accent → +9 coherence+color (§C0, §2)
3. Drop the 1px borders, use tone + ≤8% shadow         → +4 cards  (§7)

Re-score after: ~92 / 100.

Use letter bands: 90+ A · 80-89 B · 70-79 C · 60-69 D · <60 F.

Gate mode (use this as the Quality Gate before showing the user UI)

The Quality Gate (CLAUDE.md / AGENTS.md) is /ss-score run as a loop, not a one-off:

  1. Score the just-generated UI.
  2. If < 80, apply the "fix first" list (use /ss-review to make the edits), then re-score.
  3. Repeat up to ~3×, or until ≥ 80.
  4. Present the UI with the final score and a one-line "fixed: …".

The pass bar is a floor, not a ceiling — get to ≥ 80 and stop; don't chase 100. The point is that no first-draft, obviously-incoherent UI reaches the user. Especially never ship below 80 with a rainbow status list, emoji icons, two accents, or missing states — those are the exact tells the gate exists to catch.

Rules

  • Read the file — score from real evidence (line numbers), never guess.
  • Order the "fix first" list by score gain, not by severity alone — the goal is the fastest path to a better number.
  • For a directory, print a one-line score per file, then the lowest-scoring file's full breakdown.
  • Don't auto-edit in plain scoring. /ss-score measures; /ss-review and /ss-motion fix. In Gate mode (above) you do fix-and-re-score until the floor is met.
  • As a gate, ≥ 80 is a floor before showing the user — but don't over-polish: chasing 95→100 to delay shipping is worse than shipping a clean 85.

Limitations

  • Use this skill only when the task clearly matches its upstream source and local project context.
  • Verify commands, generated code, dependencies, credentials, and external service behavior before applying changes.
  • Do not treat examples as a substitute for environment-specific tests, security review, or user approval for destructive or costly actions.
