Design system patterns for reusable UI via atomic design, Tailwind tokens/variants, and accessibility. Use when creating atoms/molecules, theming, or hardening a11y.

Entity Framework Core best practices for configuration, queries, concurrency, and multi-tenancy.

Frontend architecture patterns for React apps (React Router 7, TanStack Query). Use when planning features, defining routes, data strategies, and component gaps.

Infrastructure standards for Docker, scripts, middleware, and authentication in multi-tenant deployments.

Integration testing performance optimization, test parallelization, cleanup strategies, and CI/CD categorization patterns. Use when optimizing test execution speed, managing test data, or structuring tests for automated pipelines.

ASP.NET Core Minimal APIs patterns for endpoints, DTOs, validation, and service integration. Use when implementing API endpoints, defining request/response contracts, or structuring API projects with clean separation of concerns.

Multi-tenancy implementation patterns for row level security, tenant isolation, and data segregation in SaaS applications.

End-to-end testing patterns with Playwright. Use when writing or debugging E2E tests, focusing on reliability, isolation, and flakiness prevention.

Use when writing or editing documentation, docs, READMEs, or skill/command content. Applies firm, consistent tone: state recommendations clearly, avoid soft language that contradicts or weakens your own advice, and do not offer outs that undermine the main recommendation.

Defines the format and opinions for example factories: schema (factory items with name only), prompt file layout by naming convention, prompt content formats (skills, agents, commands, workflows), and hover tooltip behavior. Use when adding or editing example factories, prompt markdown files, or the ExampleFactorySection/ExampleFactoriesList components.

Guidance and best practices for Astro components in Starlight projects. Use when building or editing .astro components: presentational vs wrapper components, props and TypeScript interfaces, slots, reusing Section/Grid/Card and Starlight Icon, styling with cascade layers, and keeping data separate from presentation so content collections and MDX integration stay clean.

Implements Astro Starlight data-driven sections using content collections (glob loader + Zod schema), presentational components, and MDX integration. Use when adding example factories, feature grids, or any "one JSON file per entry" content; defining collections in content.config.ts; or wiring getCollection into docs pages.

Guide for creating effective skills. This skill should be used when users want to create a new skill (or update an existing skill) that extends Claude's capabilities with specialized knowledge, workflows, or tool integrations.
