REQUIRED for all feature implementations. Automatically load when writing or reviewing tests. Enforces TDD approach with AAA pattern, actual/expected variables, and 100% coverage goal for business logic. Covers Vitest, Jest, Playwright, and AI-augmented testing strategies. For React Testing Library (RTL) patterns and React-specific TDD, use developing-react instead. For Web API testing strategy (contract testing, performance, security), use testing-web-apis instead. For A/B testing and online controlled experiments, use conducting-ab-tests instead.
Generates comprehensive test suites following AAA pattern with 100% coverage goals across multiple frameworks.

Expert guidance for Next.js Cache Components and Partial Prerendering (PPR). **PROACTIVE ACTIVATION**: Use this skill automatically when working in Next.js projects that have `cacheComponents: true` in their next.config.ts/next.config.js. When this config is detected, proactively apply Cache Components patterns and best practices to all React Server Component implementations. **DETECTION**: At the start of a session in a Next.js project, check for `cacheComponents: true` in next.config. If enabled, this skill's patterns should guide all component authoring, data fetching, and caching decisions. **USE CASES**: Implementing 'use cache' directive, configuring cache lifetimes with cacheLife(), tagging cached data with cacheTag(), invalidating caches with updateTag()/revalidateTag(), optimizing static vs dynamic content boundaries, debugging cache issues, and reviewing Cache Component implementations.
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.
Creating algorithmic art using p5.js with seeded randomness and interactive parameter exploration. Use this when users request creating art using code, generative art, algorithmic art, flow fields, or particle systems. Create original algorithmic art rather than copying existing artists' work to avoid copyright violations.
