+## Use AI coding tools for test workflows
+
+The packages in this article let MTP extensions call AI models during a test run. To use an AI coding assistant to create, analyze, or migrate tests in your repository, use the curated [.NET Agent Skills](https://github.com/dotnet/skills) instead.
+
+Choose a workflow based on your goal:
+
+| Goal | Skill or agent |
+|---|---|
+| Create or extend tests | Use the [`code-testing-agent` skill](https://github.com/dotnet/skills/tree/main/plugins/dotnet-test/skills/code-testing-agent) from the [`dotnet-test` plugin](https://github.com/dotnet/skills/tree/main/plugins/dotnet-test). The skill researches the codebase, plans the work, implements tests, and verifies the changes. |
+| Run or troubleshoot tests | Use the [`run-tests` skill](https://github.com/dotnet/skills/tree/main/plugins/dotnet-test/skills/run-tests) to execute tests or diagnose test execution without changing test code. |
+| Audit test quality | Use the [`test-quality-auditor` agent](https://github.com/dotnet/skills/blob/main/plugins/dotnet-test/agents/test-quality-auditor.agent.md) for a broad assessment, or invoke a focused skill from the [`dotnet-test` skills directory](https://github.com/dotnet/skills/tree/main/plugins/dotnet-test/skills) for assertions, coverage, test gaps, or test smells. |
+| Improve testability | Use the [`testability-migration` agent](https://github.com/dotnet/skills/blob/main/plugins/dotnet-test/agents/testability-migration.agent.md) to find static dependencies and introduce testable abstractions. |
+| Migrate a test framework or platform | Use the [`test-migration` agent](https://github.com/dotnet/skills/blob/main/plugins/dotnet-test-migration/agents/test-migration.agent.md) from the [`dotnet-test-migration` plugin](https://github.com/dotnet/skills/tree/main/plugins/dotnet-test-migration). The agent detects the current setup and selects the appropriate migration skill. |
+
+For installation steps and supported coding agents, see the [.NET Agent Skills repository](https://github.com/dotnet/skills#installation). Install `dotnet-test` alongside `dotnet-test-migration` because migration workflows reuse its platform detection and test verification skills.
+
 ## Choose the packages
 
 Add the abstractions package when you author an extension that consumes a chat client. Add a provider package to the test application that hosts the extension:

 Hot reload lets you modify your app's managed source code while the application is running, without the need to manually pause or hit a breakpoint. Simply make a supported change while the app is running and select the **Apply code changes** button in Visual Studio to apply your edits.
 
+If you use an AI coding assistant, the [`mtp-hot-reload` .NET Agent Skill](https://github.com/dotnet/skills/tree/main/plugins/dotnet-test/skills/mtp-hot-reload) guides the assistant through setup and recovery from unsupported edits. This skill isn't an MTP extension or CLI plugin.

 > The current version is limited to supporting hot reload in "console mode" only. There is currently no support for hot reload in Test Explorer for Visual Studio or Visual Studio Code.

+> To automate a repository-wide migration with an AI coding assistant, install the [`dotnet-test`](https://github.com/dotnet/skills/tree/main/plugins/dotnet-test) and [`dotnet-test-migration`](https://github.com/dotnet/skills/tree/main/plugins/dotnet-test-migration) plugins from [.NET Agent Skills](https://github.com/dotnet/skills).

Review the generated changes before you merge them.
