Development

Write minimal, focused tests that cover core user flows and primary workflows without over-testing during development. Use this skill when deciding what to test, writing behavior-focused tests, naming test cases clearly, mocking external dependencies, or keeping tests fast. Apply when completing feature implementation and adding strategic tests, testing critical paths rather than edge cases, or deferring edge case testing to dedicated testing phases.

Applies Anthropic's official brand colors and typography to any sort of artifact that may benefit from having Anthropic's look-and-feel. Use it when brand colors or style guidelines, visual formatting, or company design standards apply.

Build responsive, mobile-first user interfaces that adapt gracefully across all screen sizes using fluid layouts, relative units, breakpoints, and optimized assets. Use this skill when creating or modifying UI layouts, responsive components, CSS media queries, or any code that needs to adapt to different viewport sizes. Use this when implementing mobile-first designs, adding responsive breakpoints (mobile/tablet/desktop), using relative units (rem/em), ensuring touch-friendly tap targets, optimizing images for different screen sizes, testing across multiple devices, or making typography readable on all screens. Use this when working on layout components, grid systems, or any UI code that should respond to screen size changes.
