+description: Generate a TypeScript AppHost from an existing C# example AppHost, then add a TypeScriptAppHostTest-based integration test.
+---
+
+# Aspire TypeScript AppHost Generator
+
+Use this skill when the user wants to create a TypeScript AppHost (`apphost.mts`) from an existing C# example AppHost and add/update the corresponding integration test.
+
+## Prompting rule
+
+- Ask for the integration **only when this skill is actively running** and only if the user did not provide it.
+- Do not ask for integration selection before this skill is invoked.
+
+## Goal
+
+For one integration, produce:
+
+1. A TypeScript AppHost example beside the existing C# AppHost example.
+2. A test in the integration's `tests/CommunityToolkit.Aspire.Hosting.<Integration>.Tests` project that uses `TypeScriptAppHostTest.Run(...)`.
+
+## Workflow
+
+1. Resolve the integration
+   - If the user already specified an integration, use it.
+   - Otherwise, prompt for it at runtime.
+
+2. Locate the source AppHost and test project
+   - Source C# example path pattern:
+     - `examples/<example>/CommunityToolkit.Aspire.Hosting.<Integration>.AppHost/Program.cs`
+   - Target TypeScript example path pattern:
+     - `examples/<example>/CommunityToolkit.Aspire.Hosting.<Integration>.AppHost.TypeScript/`
+   - Test project path:
+     - `tests/CommunityToolkit.Aspire.Hosting.<Integration>.Tests/`
+
+3. Create or update the TypeScript AppHost folder
+   - Required files:
+     - `apphost.mts`
+     - `aspire.config.json`
+     - `package.json`
+     - `tsconfig.json`
+     - `eslint.config.mjs`
+     - `package-lock.json`
+   - Keep template/config conventions aligned with existing TypeScript AppHost examples in this repo.
+   - Use TypeScript API method names generated for Aspire exports (for overloads, use the exported TypeScript name, not guessed C# casing).
+
+4. Translate C# AppHost logic to TypeScript
+   - Preserve resource naming and behavior where practical.
+   - Use TypeScript Aspire methods and options shapes.
+   - Keep path handling and package mapping valid for the example location.
+
+5. Add the integration TypeScript AppHost test
+   - Add `TypeScriptAppHostTests.cs` in the integration test project if missing.
+   - Use:
+     - `TypeScriptAppHostTest.Run(...)`
+     - `appHostProject` = `<Integration>.AppHost.TypeScript` folder name
+     - `packageName` = integration package name
+     - `exampleName` = example folder name
+     - `waitForResources` = resources required to verify startup in Aspire
+   - Follow existing test style and attributes (`[RequiresDocker]` when applicable).
+
+6. Validate changes
+   - Run the relevant test project to ensure the TypeScript AppHost compiles and starts via the shared validation flow.
+
+## Guardrails
+
+- Do not edit generated `.aspire/modules/` files.
+- Do not change unrelated examples or tests.
+- Keep all changes scoped to the selected integration plus the skill files.
