StencilJS component patterns for this workspace. Use when creating new Stencil components, adding reactive state with @stencil/store or @ssv/tanstack.stencil-store, implementing ReactiveController from @ssv/stencil-core, or working with output targets. Trigger words - component, stencil, @Component, store, reactive controller, SsvElement, output target, web component, useSelector, useAtom, tanstack.

Write and review Vitest tests for Stencil hooks and controllers in this workspace. Use when writing *.spec.ts files, working with TestHost/DomTestHost, using mount/mountDom APIs, testing lifecycle phases, context resolution, or reactive controllers. Trigger words - spec, test, TestHost, mount, mountDom, useEffect, useQuery, useSelector, vitest, lifecycle test, controller test, it.each, afterConnect.

Reference for Stencil component initialization order across rendering modes (SSR, client navigation, and hydration). Use when writing code that depends on parent-child initialization sequence, context resolution, `hostConnected` or `hostWillLoad` timing, or `globalThis`/`window` availability in Stencil components. Trigger words — initialization order, hydration, SSR init, hostConnected order, context timing, window in SSR, globalThis, bottom-up, top-down. Do not use for general component authoring, output-target configuration, or non-Stencil frameworks.

Implement command pattern in Angular using @ssv/ngx.command library. Use for encapsulating actions with execution state tracking, enabling/disabling controls, and managing async operations. Triggers on button states, action execution, form submissions, or implementing command pattern.

Write unit and integration tests for Angular v21+ applications using Vitest or Jasmine with TestBed, component harnesses, and modern testing patterns. Use for testing components with signals, OnPush change detection, services with inject(), and HTTP interactions. Triggers on test creation, testing signal-based components, mocking dependencies, or setting up test infrastructure.

Use when building .NET 10 or C# 14 applications; when using minimal APIs, modular monolith patterns, or feature folders; when implementing HTTP resilience, Options pattern, Channels, or validation; when seeing outdated patterns like old extension method syntax

Microsoft Orleans best practices for this codebase. Use when writing or reviewing grain interfaces, grain implementations, serialization attributes, concurrency attributes, grain key strategies, storage providers, or tenant-scoped grain patterns. Use for [Immutable], [return: Immutable], [GenerateSerializer], [AlwaysInterleave], [OneWay], [StatelessWorker], [Reentrant], ITenantGrain, IWithTenantAccessor, TenantGrainKey, and StorageProvider patterns.
