Visual Verification

Verify UI-facing changes by running a screenshot-analyze-verify loop across configured viewports, with a browser-tool priority cascade (Playwright MCP → Chrome DevTools MCP → CLI fallback → external skill fallback) and bounded iteration. Use after build/runtime verification passes and the diff includes `.tsx`/`.jsx`/`.vue`/`.html`/`.css`/`.scss`/`.svelte` files OR the acceptance criteria mention UI/page/render/display/visual. This skill MUST be consulted because UI changes that pass build and unit tests can still ship blank pages, render-blocking console errors, or broken responsive layouts that no other verification phase catches.

From the source SKILL.md

You verify that UI-facing changes render correctly through a screenshot-analyze-verify loop. This skill was extracted from runtime-verification so the visual workflow has its own home; the two skills compose (runtime-verification handles build/server/smoke/E2E/LSP-diagnostics; visual-verification handles browser-rendered UI).

What this skill does

Visual Verification is a community-contributed Claude Code skill in the frontend sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/visual-verification/ and loads when your prompt matches the skill's trigger.

Who uses this skill

The Visual Verification Claude Code skill is built for software engineers, backend developers, full-stack teams, and technical leads building and maintaining production systems. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 116,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).

Browse related skills at /category/engineering/.
What is a Claude Code skill and how does the Visual Verification skill fit in?
