.NET and ASP.NET Core security patterns. Covers Identity, authentication, dependency auditing, secure coding practices, and OWASP for .NET ecosystem. USE WHEN: user works with "C#", ".NET", "ASP.NET Core", "Entity Framework", asks about ".NET vulnerabilities", "NuGet security", ".NET authentication", "Blazor security" DO NOT USE FOR: general OWASP concepts - use `owasp` or `owasp-top-10` instead, Java/Python security - use language-specific skills
Grafana Pyroscope continuous profiling platform. Covers instrumentation of Go/Java/Python/Ruby/Node.js/ .NET/Rust apps via SDKs or eBPF (Alloy), flame graph analysis, ProfileQL queries, server configuration and architecture, Grafana Cloud Profiles integration, and trace-profile linking (Span Profiles). Use when working with profiling data, instrumenting apps for Pyroscope, analyzing performance profiles, or deploying Pyroscope server.
Освойте enterprise-разработку на TypeScript с типобезопасными паттернами, современными инструментами и интеграцией с фреймворками. Этот навык предоставляет всестороннее руководство по TypeScript 5.9+, охватывая основы системы типов (дженерики, маппинг типов, условные типы, оператор satisfies), enterprise-паттерны (обработка ошибок, валидация с помощью Zod), NestJS для масштабируемых API и LangChain.js для AI-приложений. Используйте при создании типобезопасных приложений, миграции кодовых баз с JavaScript, настройке современных инструментов (Vite 7, pnpm, ESLint, Vitest), внедрении продвинутых паттернов типизации или сравнении TypeScript с подходами Java/Python.
Work with the @upstash/box TypeScript/JavaScript SDK for sandboxed cloud containers with AI agents, shell, filesystem, and git. Use when building with Upstash Box, creating sandboxed environments, running AI agents in containers, or orchestrating parallel boxes.
Send an email to a mailing list via the SchemaVaults mail-server `/api/send` route, using either the `sendEmailToMailingList()` helper or the `schemavaults-send-email send-to-mailing-list` CLI from `@schemavaults/send-email`. Use when any server-side TypeScript/JavaScript code needs to send a notification to a mailing list audience — **or when Claude Code itself wants to send a one-shot notification at the end of a task** (preferred — invoke the CLI via `bunx schemavaults-send-email send-to-mailing-list …`; fallback — write a short script to `/tmp/` and run it with `bun`).
Create AI videos with HyperFrames in Hermes using HTML, CSS, and JavaScript compositions, then validate and render them to MP4. Use for short video intros, cinematic trailers, product promos, subtitle animations, HUD/tech visuals, web-to-video work, and motion graphics.
Find focused, runnable Deepgram recipes for a specific feature × language. Use whenever someone wants a minimal working code snippet for ONE feature (transcribe URL, diarize, smart-format, voice agent connect, etc.) rather than a full starter app. Recipes are under 50 lines, read DEEPGRAM_API_KEY from env, and ship with a runnable example_test. Covers Python, JavaScript, Go, .NET, Java, Rust, and the Deepgram CLI.
Guides development of Fastify Node.js backend servers and REST APIs using TypeScript or JavaScript. Use when building, configuring, or debugging a Fastify application — including defining routes, implementing plugins, setting up JSON Schema validation, handling errors, optimising performance, managing authentication, configuring CORS and security headers, integrating databases, working with WebSockets, and deploying to production. Covers the full Fastify request lifecycle (hooks, serialization, logging with Pino) and TypeScript integration via strip types. Trigger terms: Fastify, Node.js server, REST API, API routes, backend framework, fastify.config, server.ts, app.ts.
Use when debugging TypeScript/JavaScript bugs by tracing call chains, understanding unfamiliar codebases quickly, making architectural decisions, or reviewing code quality. Extract function signatures and JSDoc without full file reads, trace call hierarchies up/down, detect code smells, and follow data flow. Triggers on debugging, understanding codebase, architectural analysis, signature extraction, call tracing.
Migrate Kotlin (and Java) code from kotlinx.collections.immutable 0.3.x / 0.4.x to the latest 0.5.x. The 0.5.x line renames every copy-returning method on PersistentList / PersistentMap / PersistentSet / PersistentCollection to a participial form per KEEP-0459 (add→adding, removeAt→removingAt, set→replacingAt, put→putting, clear→cleared, …) and deprecates the old names (WARNING, with ReplaceWith). Driven by the compiler: bump the version, recompile, and apply the rename each deprecation warning names. Use when the user mentions kotlinx.collections.immutable 0.5.x, PersistentList migration, "Use adding() instead", KEEP-0459, or sees deprecation warnings from kotlinx.collections.immutable.
Use when building, auditing, styling, debugging, or optimizing Apache ECharts visualizations in vanilla JavaScript, React, or Vue applications — chart setup, lifecycle management, responsive resizing, theming, large datasets, streaming updates, server-side rendering (SVG in Node), and symptoms like a blank or empty chart, a chart that does not resize or update, stale series after switching chart types, or "component not exists" errors. Not for choosing chart types or visual design, and not for other charting libraries (D3, Chart.js, Highcharts).
Framework (OSS). Migrate an existing Apple/Swift Expo native module from the Expo Modules API 1.0 definition DSL to the 2.0 macro API (sometimes called v2) while preserving its JavaScript and TypeScript contract. Use when converting or incrementally adopting @ExpoModule, @JS, @Event, @SharedObject, or @Record in an existing module. Do not use for creating a new module, general Expo SDK upgrades, or Android/Kotlin migrations.
