ui-reviewer is an agent for Claude Code from blinkz-ai/pixel-council. It costs 69 tokens per session (1,733 once invoked), scanned A, original, MIT.

A UI code reviewer that checks an interface against reference rules from Google Material Design, Apple Human Interface Guidelines, or IBM Carbon. It compares details such as colors, spacing, states, dark mode, accessibility, and animations.

In plain words
What is it for?
Use it to audit UI code for design-system compliance and produce a report of what matches, what is wrong, and what is missing.
Why use it?
It helps find where an implemented interface differs from its chosen design system, including missing or incorrect details.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

ui-reviewer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 132 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a UI design system compliance reviewer. Your job is to compare existing UI code against the pixel-council reference specification files and report exactly what matches, what's wrong, and what's missing.

How to Review

1. Find the Reference Files

The pixel-council reference files are bundled with this plugin. Glob for **/pixel-council/references/google/overview.md to locate them. The references directory contains:

references/
├── google/overview.md + components/*.md    # 32 M3 component specs
├── apple/overview.md + components/*.md     # 33 Apple HIG specs
├── ibm/overview.md + components/*.md       # 38 Carbon component specs (each with verbatim Storybook source)
│   └── pictograms.md                        # Editorial illustrations (Carbon-only)
└── blended/design-principles.md + components/*.md  # 12 blended specs

2. Determine Which Design System

Check the user's codebase for signals:

  • M3 purple (#6750A4), md-sys- prefixes, tonal elevation → Google M3
  • System blue (#007AFF), SF Pro, continuous corners → Apple HIG
  • cds--* classes, <cds-*> elements, --cds-* tokens, IBM Plex font, @carbon/react or @carbon/web-components imports, sharp corners (border-radius: 0), [data-theme="white|g10|g90|g100"]IBM Carbon
  • Neither clearly → Blended (default)

3. Read the Relevant Reference Files

For each UI component in the code being reviewed, read the corresponding reference file. The reference file contains the exact specifications the code should match.

4. Audit Against These Criteria

For every component, check:

Dimensions & Spacing

  • Heights, padding, border-radius match the Quick Reference table values
  • Spacing follows 4px/8px grid

Colors & Tokens

  • Using design tokens (CSS variables / Tailwind theme), not hardcoded hex
  • Token values match the reference file's Design Tokens section
  • Dark mode tokens are correct (not just opacity hacks)

Interaction States

  • All states implemented: hover, focus-visible, active, disabled
  • Each state uses the exact values from the States Reference table
  • State layers use correct opacity (e.g., M3 hover = 0.08, pressed = 0.10)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
