SimpleModule

Write correct ASP.NET Minimal API endpoints in the SimpleModule modular monolith. Use when creating, modifying, or reviewing any IEndpoint or IViewEndpoint implementation, or when writing endpoint code that uses parameter binding, authorization, validation, CrudEndpoints helpers, Inertia.Render, or form handling. Triggers on: "add endpoint", "create endpoint", "new endpoint", "API endpoint", "view endpoint", "MapGet", "MapPost", "MapPut", "MapDelete", "Inertia.Render", route handling, parameter binding questions, "FormRequest", "Route const", "IAuthorizer", "policy", "RequirePermission", or any work touching files in Endpoints/, Pages/, or FormRequests/ directories.

Scaffold a new SimpleModule module with contracts, implementation, and test projects following the project's modular monolith conventions. Use when creating a new module from scratch.

Comprehensive guide for working with the SimpleModule modular monolith framework. Use when creating modules, adding features, writing endpoints, configuring services, working with the event bus, permissions, menus, settings, database contexts, or understanding the project architecture. Triggers on: "add module", "new module", "add feature", "create endpoint", "module architecture", "how does SimpleModule work", "event bus", "permissions", "menu", "settings", "database context", "contracts", "IModule", "IEndpoint", "IViewEndpoint", "Inertia", "CrudEndpoints", "debug module", "review module", "module status", "SM00", "source generator diagnostic", "module not found", "page 404", "event bus", "settings", "IMessageBus", "Wolverine", "SettingDefinition", "policy", "IPolicy", "IAuthorizer", "entity-level authorization", "FormRequest", "Route const".

End-to-end verification of a feature implementation before opening a PR. Starts the SimpleModule.Host (killing port 5001 if occupied), drives the feature in a real browser via playwright-cli, runs every local CI step, and only then opens a pull request. Use when the user asks to "verify the feature", "test and ship", "run e2e + CI + PR", or any variation that means "prove it works, then PR it".

Use when building React 18+ applications in .jsx or .tsx files, Next.js App Router projects, or create-react-app setups. Creates components, implements custom hooks, debugs rendering issues, migrates class components to functional, and implements state management. Invoke for Server Components, Suspense boundaries, useActionState forms, performance optimization, or React 19 features.
