QA web testing skill using Chrome DevTools MCP tools for visual regression testing, responsive breakpoint validation, and CSS layout debugging. Use this skill whenever the user asks to "test a page", "check breakpoints", "verify responsive layout", "QA this page", "test CSS at different viewports", "check for layout bugs", "verify the fix", or wants to visually inspect a web page at specific viewport widths. Also triggers when the user provides a URL and asks to take screenshots, compare layouts, or inspect element dimensions. Works with any Chrome DevTools MCP-connected browser session on localhost or staging environments.
Type-driven design principle: transform unstructured data into structured types at system boundaries, making illegal states unrepresentable. Use when writing or reviewing code that validates input, designs data types, defines function signatures, handles errors, or models domain logic. Use when you see validation functions that return void/undefined, redundant null checks, stringly-typed data, boolean flags controlling behavior, or functions that can receive data they shouldn't. Triggers on: "parse don't validate", "type-driven design", "make illegal states unrepresentable", "input validation", "data modeling", "refactor types", "strengthen types", "smart constructor", "newtype", "branded type".
Design LLM-as-Judge evaluators for subjective criteria that code-based checks cannot handle. Use when a failure mode requires interpretation (tone, faithfulness, relevance, completeness). Do NOT use when the failure mode can be checked with code (regex, schema validation, execution tests). Do NOT use when you need to validate or calibrate the judge — use validate-evaluator instead.
Sample skill for testing the skill-tester validation pipeline. Demonstrates proper skill structure with scripts, references, and assets.
Guide for building UI with Base UI React (@base-ui/react), a headless, accessible component library using compound component patterns. Use this skill whenever the user is building or modifying any user interface in React, including forms and validation, navigation and menus, modals and overlays, selection controls, toast notifications, accordions, tabs, or any interactive UI component. Also trigger when the user mentions @base-ui/react, Base UI, headless components, migrating from Radix UI, or asks about accessible component patterns. Even if the user does not explicitly mention Base UI, use this skill whenever they are creating React UI components, building a design system, or working on frontend user experience.
