Why should I use this if my unit tests already pass?

Automated unit tests can miss visual regressions, layout overlaps, or subtle interaction bugs that only surface in a real browser environment or during manual interaction.

What is the purpose of the Visual Verification skill?

It provides a framework for Claude to verify that UI features actually work in a browser, preventing tasks from being marked complete based only on passing unit tests.

Can it capture evidence of testing?

Yes, the skill specifically includes a checklist item for capturing screenshots as evidence that the feature renders and behaves correctly.

Does this skill work with mobile apps?

While currently optimized for web applications via Playwright, the skill framework includes patterns for mobile application verification that are being expanded.

Security & Testing

Validates frontend implementations through interactive browser testing and structured visual checklists.

About

The Visual Verification skill enables Claude to move beyond simple code analysis by implementing a rigorous process for testing user interfaces in real browser environments. It provides standardized workflows for checking UI rendering, user interactions, and edge cases using tools like Playwright, ensuring that passing automated tests translates to a truly functional user experience before a task is finalized.
