axe-core - accessibility testing engine for automated WCAG compliance checks. USE WHEN: user mentions "axe", "automated accessibility testing", "a11y tests", asks about "integrating accessibility checks", "CI/CD accessibility", "Playwright accessibility", "Jest accessibility", "Vitest axe" DO NOT USE FOR: manual accessibility audits - use `wcag` skill instead
JaCoCo Java code coverage tool USE WHEN: user mentions "JaCoCo", "Java coverage", "code coverage", asks about "coverage threshold", "jacoco-maven-plugin", "coverage report", "LINE coverage", "BRANCH coverage" DO NOT USE FOR: JavaScript/TypeScript coverage - use Vitest skill, SonarQube analysis - use `sonarqube` skill, test execution - use testing skills
TDD patterns, test writing strategies, coverage guidance, mocking patterns. Use when: write tests, TDD, test coverage, unit test, integration test, E2E test, mocking, test organization, pytest, vitest, jest.
Rust testing with cargo test, tokio-test, and mockall. Covers unit tests, integration tests, async testing, mocking, and benchmarks. USE WHEN: user mentions "rust test", "cargo test", "mockall", asks about "#[test]", "#[tokio::test]", "proptest", "criterion", "async rust testing" DO NOT USE FOR: JavaScript/TypeScript - use `vitest` or `jest`; Java - use `junit`; Python - use `pytest`; Go - use `go-testing`; E2E browser tests - use Playwright
Crée des interfaces frontend distinctives, de qualité production, avec un haut niveau de design. À utiliser quand l'utilisateur demande de construire des composants web, pages, artefacts, posters ou applications (exemples : sites web, landing pages, dashboards, composants React, mises en page HTML/CSS, ou pour styliser/embellir toute interface web). Génère du code créatif et soigné qui évite l'esthétique générique de l'IA.
TanStack Router bundler plugin for route generation and automatic code splitting. Supports Vite, Webpack, Rspack, and esbuild. Configures autoCodeSplitting, routesDirectory, target framework, and code split groupings.
Use this skill whenever writing, reviewing, debugging, or refactoring TypeScript code that uses the Effect-TS library. Trigger when you see imports from `effect`, `effect/*`, or any `@effect/*` scoped package (schema, platform, sql, opentelemetry, cli, cluster, rpc, vitest). Trigger on Effect-specific constructs: Effect.gen generators, Schema.Struct/Schema.Class definitions, Layer/Context.Tag/Service patterns, Effect.pipe pipelines, Data.TaggedError/Data.Class error types, Ref/Queue/PubSub/Deferred concurrency primitives, Match module, Config providers, Scope/Exit/Cause/Runtime patterns, or any code using Effect's typed error channel (E parameter). Also trigger when the user asks about Effect patterns, migration from Promises/fp-ts/neverthrow to Effect, or how to structure an Effect application. Covers the full ecosystem: core Effect type, Schema validation, error management, concurrency (fibers, queues, semaphores, pools), streams/sinks, services and layers (DI), resource management, scheduling, observability, platform APIs, and AI integration. Do NOT trigger for React's useEffect, Redux side effects, or general English usage of "effect" unless the context clearly involves the Effect-TS library.
This skill should be used when the user wants to implement features or fix bugs using test-driven development. Enforces the RED-GREEN-REFACTOR cycle with vertical slicing, context isolation between test writing and implementation, human checkpoints, and auto-test feedback loops. Uses multi-agent orchestration with the Task tool for architecturally enforced context isolation. Supports Jest, Vitest, pytest, Go test, cargo test, PHPUnit, and RSpec.
TypeScript best practices, type safety, and toolchain standards. Use when: - Writing or reviewing TypeScript code - Setting up TypeScript projects or tsconfig - Choosing state management patterns - Configuring build tools (tsup, Vitest) - Avoiding type gymnastics or any-abuse Keywords: TypeScript, tsconfig, strict mode, no-any, pnpm, Vitest, tsup, TanStack Query, discriminated unions, type safety, ESLint
Integrate and implement apps and screens using gts-central-library tokens, styles, and components. Use when adding the design system to Vite, Next.js, Lovable, or React apps; migrating from shadcn or parallel token systems; setting up Tailwind v4 with GTS css; implementing configurator-style layouts; or troubleshooting token/theme/style mismatches.
Integrate TheSys C1 Generative UI API to stream interactive React components (forms, charts, tables) from LLM responses. Supports Vite+React, Next.js, and Cloudflare Workers with OpenAI, Anthropic Claude, and Workers AI. Use when building conversational UIs, AI assistants with rich interactions, or troubleshooting empty responses, theme application failures, streaming issues, or tool calling errors.
shadcn/ui — copy-owned React component library built on Radix UI and Tailwind CSS. Use when building with shadcn/ui or asking about its components, CLI, theming, configuration, or integration with Next.js, Vite, Remix, or other frameworks. Fetch live documentation for up-to-date details.
