visual-qa-verification

visual-qa-verification is a skill for Claude Code from PMDevSolutions/Aurelius. It costs 81 tokens per session (3,700 once invoked), scanned A, original, MIT.

A visual quality-check guide for comparing a web app with its Figma design, using screenshots and pixel-level image differences. It also covers responsive layouts, accessibility, performance, and browser rendering.

In plain words
What is it for?
It is for checking Figma-to-React pages, comparing screenshots, testing different screen sizes and browsers, and confirming that images and other assets render correctly.
Why use it?
Build and type checks cannot show whether a page looks correct to users. This guide catches visual, responsive, asset, accessibility, and performance problems after a design is converted into React.

Skill for Claude Code

Written for Claude Code: installed under .claude/.

Not installable on its own: it runs a file from its repository that does not travel with it. Clone the repository, or install whatever ships that file. The line is ./scripts/cross-browser-baseline.sh compare http://localhost:3000 --json.

Getting it into your agent

There is no command for this one: it runs only inside a plugin, and the catalogue could not identify which plugin ships it. The source is linked below.

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

visual-qa-verification 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 yesterday.

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.

Visual QA Verification

Overview

After the figma-react-converter agent generates React components and pages, this skill guides verification that the output matches the Figma source design. It covers screenshot comparison, responsive behavior, accessibility, performance, and asset rendering.

Core Principle: Every converted design must be visually verified before delivery. Build checks validate structure and types; this skill validates what the user actually sees in the browser.

When to Use

Use this skill when:

  • A Figma-to-React conversion has just completed
  • Verifying generated components match their Figma source
  • Running post-conversion visual QA
  • Checking responsive behavior of generated pages
  • Validating that all images and assets render correctly

Symptoms that trigger this skill:

  • "verify app"
  • "visual QA"
  • "compare to Figma"
  • "check screenshots"
  • "does it match the design"
  • "responsive check"
  • "pixel-perfect"

Verification Checklist

Run these checks in order after conversion completes.

Step 1: Start Development Server

Start the React application and verify it builds and renders without errors.

# Install dependencies
pnpm install

# Start dev server
pnpm dev

# Verify build passes (catches TypeScript errors, missing imports)
pnpm build

Check the terminal output for:

  • Zero TypeScript errors
  • Zero import resolution failures
  • No runtime console errors on initial load

Open the browser console and verify no errors or warnings appear on page load.

Step 2: Automated Visual Diff Loop

This is the core pixel-perfect iteration loop. It compares app screenshots against Figma source screenshots using pixelmatch via scripts/visual-diff.js.

Configuration: Read .claude/pipeline.config.json for thresholds and iteration limits:

  • iterationLoop.maxVisualIterations — max fix attempts (default: 5)
  • iterationLoop.diffPassThreshold — max mismatch ratio to pass (default: 0.02 = 2%)
  • iterationLoop.diffWarnThreshold — mismatch ratio that triggers warning (default: 0.05 = 5%)
  • iterationLoop.regionAnalysis — enable per-region diff reporting (default: true)
  • visualDiff.breakpoints — breakpoints to test

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.

visual-qa-verification is a skill published in the GitHub repository PMDevSolutions/Aurelius (8 stars, last pushed 21d ago), licensed MIT. It adds 81 tokens to every session and 3,700 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-04.
