Use when a TypeScript/JavaScript task needs symbol navigation (`nav declarations|definition|references`), structural pattern search (`search`), structural rewrites (`patch`), or reference-based blast-radius estimation (`code-rank`). Prefer for compact, scoped repository analysis and migration work; do not use for runtime-path proofs, correctness guarantees, or replacing compiler/tests.
HTTP API testing for TypeScript (Supertest) and Python (httpx, pytest). Test REST APIs, GraphQL, request/response validation, authentication, and error handling.
This skill should be used when developing Next.js 16 applications with React, TypeScript, Material-UI V7, and Firebase. Provides comprehensive guidance on setup, best practices, error handling, and advanced patterns for production-ready applications.
Generates dead code detection configurations for loom plan verification. Provides language-specific commands, fail patterns, and ignore patterns for Rust, TypeScript, Python, Go, and JavaScript. Use when adding code quality checks to acceptance criteria or truths fields in loom plans. Dead code detection catches incomplete wiring by identifying code that exists but is never called.
Setup Sentry Tracing (Performance Monitoring) in any project. Use this when asked to add performance monitoring, enable tracing, track transactions/spans, or instrument application performance. Supports JavaScript, TypeScript, Python, Ruby, React, Next.js, and Node.js.
Bootstrap new projects with strong typing, linting, formatting, and testing. Supports Python, TypeScript, and other languages with research fallback.
React Native with Expo framework for building native mobile apps on Android, iOS, and web from a single TypeScript codebase. Covers Expo Router file-based navigation (stack, tabs, drawer), EAS Build/Submit/Update for CI/CD and OTA updates, expo-dev-client for custom development builds, Expo Modules API for native Swift/Kotlin modules, core RN patterns (StyleSheet, FlatList, Platform-specific code), native device APIs (camera, notifications, haptics), and NativeWind for Tailwind CSS styling. Use when building React Native apps with Expo, configuring Expo Router navigation, setting up EAS Build pipelines, implementing OTA updates, creating native modules, or integrating device APIs like camera and push notifications.
Knip dead code detection best practices for JavaScript and TypeScript projects. Use when configuring Knip, analyzing unused code, setting up CI integration, or cleaning up codebases. Triggers on knip.json, dead code, unused exports, unused dependencies, bundle optimization.
Write and review unit tests for Vue 3 + TypeScript + Vitest + Pinia codebases. Use when creating or updating tests for components, composables, and stores; mocking Pinia with createTestingPinia; applying Vue Test Utils patterns; and enforcing black-box assertions over implementation details.
Standards de codage universels, bonnes pratiques et patrons pour le développement TypeScript, JavaScript, React et Node.js.
Add LangWatch tracing and observability to your code. Use for both onboarding (instrument an entire codebase) and targeted operations (add tracing to a specific function or module). Supports Python and TypeScript with all major frameworks.
Build type-safe validated forms using React Hook Form v7 and Zod v4. Single schema works on client and server with full TypeScript inference via z.infer. Use when building forms, multi-step wizards, or fixing uncontrolled warnings, resolver errors, useFieldArray issues, performance problems with large forms.
