## Description

Build provider-agnostic .NET AI integrations with `Microsoft.Extensions.AI`, `IChatClient`, embeddings, middleware, structured output, vector search, and evaluation. USE FOR: building or reviewing .NET code that uses Microsoft.Extensions.AI, Microsoft.Extensions.AI.Abstractions, IChatClient, IEmbeddingGenerator, ChatOptions, or AIFunction;. DO NOT USE FOR: unrelated stacks; generic tasks that do not need this specific guidance. INVOKES: inspect the repository context, edit targeted files, and run relevant build, test, lint, or validation commands when changes are made.

# Microsoft.Extensions.AI

## Trigger On

- building or reviewing `.NET` code that uses `Microsoft.Extensions.AI`, `Microsoft.Extensions.AI.Abstractions`, `IChatClient`, `IEmbeddingGenerator`, `ChatOptions`, or `AIFunction`
- adding `IImageGenerator`, local-model chat via Ollama, AI app templates, or the `.NET AI` quickstarts for assistants and MCP
- choosing between low-level AI abstractions, provider SDKs, vector-search composition, evaluation libraries, and a fuller agent framework
- adding streaming chat, structured output, embeddings, tool calling, telemetry, caching, or DI-based AI middleware
- wiring `Microsoft.Extensions.VectorData`, `Microsoft.Extensions.DataIngestion`, MCP tooling, or evaluation packages around a provider-agnostic AI app
