Automated safety checks
This skill passed all 6 checks. We read its files at one commit and looked for the things that make a skill dangerous to run — not for whether it works.
Declares what it does: passed
SKILL.md parses and declares a name and a description.
SKILL.md exists, its frontmatter parses, and it declares a name and a description.
No undeclared network calls: passed
Makes no network calls.
Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.
No obfuscated payloads: passed
No encoded or obfuscated payloads.
No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.
No credential access: passed
Reads no keys, tokens, keychains or credential files.
Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.
No pipe-to-shell installers: passed
No pipe-to-shell or download-and-run installers.
No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.

About this skill
What it does
Visual regression testing compares screenshots of a user interface across different builds to detect unintended visual changes. It ensures that layout shifts, color mismatches, or broken elements do not degrade the user experience after code updates.
When to use it
- UI Redesigns: Verify that new CSS frameworks or component libraries render correctly without breaking existing layouts.
- Theme Switching: Ensure dark mode, light mode, and other theme variations display consistently across all pages.
- Responsive Design: Confirm that the interface adapts properly when viewed on mobile devices versus desktop screens.
- Accessibility Audits: Catch visual regressions that might impact screen readers or keyboard navigation flows.
Key capabilities
- Automates screenshot capture of specific UI states during test execution.
- Performs pixel-by-pixel comparison between current and baseline images.
- Generates detailed reports highlighting exact locations of visual discrepancies.
- Integrates with continuous integration pipelines for automated quality gates.
Example prompts
- "Run a visual regression test comparing the latest build against our approved baseline screenshots."
- "Identify any layout shifts in the checkout flow after deploying the new payment gateway component."
- "Generate a report of all color contrast violations found in the mobile navigation menu."
Tips & gotchas
Visual regression testing requires maintaining an up-to-date library of baseline images; stale baselines will cause false positives. For best results, configure tests to run only on critical user journeys rather than every single screen to reduce noise and execution time.
