testing-visual-regression
Detect visual changes in UI components using screenshot comparison.
Examining code for the line that is wrong
What it does
Detect unintended visual changes in UI components by capturing screenshots and comparing them pixel-by-pixel against approved baselines. Supports Playwright visual comparisons, Percy, Chromatic, BackstopJS, and reg-suit.
Use when detecting unintended UI changes or pixel differences
You don’t need to name it. Ask for the job in your own words — your AI loads the skill when the request matches.
What it can touch
Includes 4 scripts
Your AI can run these when the skill is used — on your computer in a coding tool (which asks first unless you have told it not to), or in the AI’s own sandbox in Claude and ChatGPT.
How we know
Found in the skill’s folder: assets/example_backstop_config.js, scripts/analyze_diffs.py, scripts/run_visual_tests.py, scripts/update_baselines.py.
Mentions 4 outside web addresses
The instructions point your AI at these sites or APIs. Anything it sends there leaves your computer.
How we know
Web addresses in the SKILL.md, excluding GitHub and documentation sites: playwright.dev, reg-viz.github.io, www.chromatic.com, www.percy.io.
Lets your AI use some powerful tools without asking, while the skill is in use
While the skill is working, Claude Code will not ask before using these tools.
How we know
SKILL.md line 1: “allowed-tools: Read, Write, Edit, Grep, Glob, Bash(test:visual-*)”. Read 2026-10-05, commit 680131e.
SKILL.md, line 1 ↗No serious risk pattern found
Launch7’s automated check read all 11 text files in this skill and matched none of its serious risk patterns. This is not a guarantee: a check like this can miss new or disguised tricks, and the author can change the files after the check.
How we know
Read 2026-10-05, commit 680131e by pipeline/trust/analyze.py — 40+ patterns for hidden text, prompt injection, downloads that run, credential access and more. It reads; it never runs the skill.

Read automatically from the skill’s own files on GitHub on 5 Oct 2026. Launch7 does not run or manually review skills: this lists what the check saw, and nothing here means “safe”. How we check
Add it to your AI
Partly. Upload it in Claude’s settings — the instructions work; the scripts need the full folder.
Built in your browser from the SKILL.md on GitHub — nothing passes through Launch7.
In Claude, open Customize → Skills, press +, then Create skill → Upload a skill, and choose the .zip.
Make sure code execution is switched on (Settings → Capabilities). Skills need it.
Start a new chat and ask for the job in your own words — Claude picks the skill up when it fits.
This skill ships 4 scripts beside its instructions. The download here is the SKILL.md alone — enough for the instructions, not for the parts that run code. Use the command route, or take the full folder from the repository.
How Claude does this: support.claude.com · checked 28 Sep 2026 · “Supported” means documented by the vendor; Launch7 has not run it end to end
