+#### Automated API Compatibility Validation
+
+The .NET projects use [Package Validation](https://learn.microsoft.com/dotnet/fundamentals/package-validation/overview)
+to automatically detect API breaking changes. This validation runs during `dotnet build`
+(Release configuration) and `dotnet pack`, comparing the current API surface against the
+latest published NuGet baseline version.
+
+**What gets validated:** By default, packable RC packages (`IsReleaseCandidate=true`) and
+GA packages (`IsGenerallyAvailable=true`) that have a published NuGet baseline and do not
+override validation settings are automatically validated. The shared baseline version and
+default validation settings are defined in `dotnet/nuget/nuget-package.props`, but
+individual projects may opt out (for example by setting `EnablePackageValidation=false`).
+
+**If the build fails with CP errors (e.g., CP0001, CP0002):**
+
+1. **Unintentional breaking change** — Refactor your code to maintain backward compatibility.
+2. **Intentional breaking change** (approved by maintainers) — Generate a suppression file:
+   ```bash
+   dotnet build <project>.csproj -c Release /p:ApiCompatGenerateSuppressionFile=true
+   ```
+   This creates or updates a `CompatibilitySuppressions.xml` in the project directory.
+   Include this file in your PR with justification for the breaking change.
+
+**After each release:**
+
+1. Delete all `CompatibilitySuppressions.xml` files from validated projects.
+2. Update `PackageValidationBaselineVersion` in `dotnet/nuget/nuget-package.props` to the
+   newly published version.
+
+For more details, see the [Package Validation diagnostic IDs](https://learn.microsoft.com/dotnet/fundamentals/package-validation/diagnostic-ids).

+## Troubleshooting
+
+### Authentication
+
+| Problem | Cause | Fix |
+|---------|-------|-----|
+| Authentication errors when using Azure credentials | Not signed in to Azure CLI | Run `az login` before starting your app |
+| API key errors | Wrong or missing API key | Verify the key and ensure it's for the correct resource/provider |
+
+> **Tip:** `DefaultAzureCredential` is convenient for development but in production, consider using a specific credential (e.g., `ManagedIdentityCredential`) to avoid latency issues, unintended credential probing, and potential security risks from fallback mechanisms.
+
+### Environment Variables
+
+The samples typically read configuration from environment variables. Common required variables:
+
+| Variable | Used by | Purpose |
+|----------|---------|---------|
+| `AZURE_OPENAI_ENDPOINT` | Azure OpenAI samples | Your Azure OpenAI resource URL |
+| `AZURE_OPENAI_DEPLOYMENT_NAME` | Azure OpenAI samples | Model deployment name (e.g. `gpt-4o-mini`) |
+| `AZURE_AI_PROJECT_ENDPOINT` | Microsoft Foundry samples | Your Microsoft Foundry project endpoint |
+| `AZURE_AI_MODEL_DEPLOYMENT_NAME` | Microsoft Foundry samples | Model deployment name |
+| `OPENAI_API_KEY` | OpenAI (non-Azure) samples | Your OpenAI platform API key |

+# Foundry agent surface stays centered on `ChatClientAgent`
+
+## Context
+
+The Microsoft Foundry integration exposes two distinct usage patterns:
+
+1. Direct Responses usage, where callers provide model, instructions, and tools at runtime.
+2. Server-side versioned agents, where callers create and manage `AgentVersion` resources through `AIProjectClient.Agents`.
+
+We briefly explored adding public wrapper types such as `FoundryAgent`, `FoundryVersionedAgent`, and `FoundryResponsesChatClient` to make those paths feel more specialized. That direction created extra public types, duplicated existing `ChatClientAgent` behavior, and pushed samples toward compatibility helpers instead of the native Azure SDK flow.
+
+## Decision
+
+Keep the public surface centered on `ChatClientAgent`.
+
+- Direct Responses scenarios use `AIProjectClient.AsAIAgent(...)`.
+- Server-side versioned scenarios use native `AIProjectClient.Agents` APIs to create or retrieve agent resources, then wrap `AgentRecord` or `AgentVersion` with `AIProjectClient.AsAIAgent(...)`.
+- Compatibility helpers such as `AIProjectClient.CreateAIAgentAsync(...)` and `AIProjectClient.GetAIAgentAsync(...)` remain only as obsolete migration shims.
+- Public wrapper types `FoundryAgent`, `FoundryVersionedAgent`, `FoundryResponsesChatClient`, and `FoundryResponsesChatClientAgent` are not part of the chosen direction.
+
+## Why
+
+- `ChatClientAgent` is already the framework abstraction used everywhere else.
+- `AIProjectClient` is the native Azure SDK entry point for versioned agent lifecycle operations.
+- A single agent abstraction avoids parallel type hierarchies for the same backend.
+- Samples become clearer when they show either:
+  - direct Responses construction via `AIProjectClient.AsAIAgent(...)`, or
+  - native Foundry resource management via `AIProjectClient.Agents`.
+
+## Consequences
+
+### Direct Responses path
+
+Use the convenience overloads on `AIProjectClient`:
+
+```csharp
+AIProjectClient aiProjectClient = new(new Uri(endpoint), credential);
+
+ChatClientAgent agent = aiProjectClient.AsAIAgent(
+    model: deploymentName,
+    instructions: "You are good at telling jokes.",
+    name: "JokerAgent");
+```
+
+Or use composed `ChatClientAgent`
+
+```csharp
+ProjectResponsesClient projectResponsesClient = new(new Uri(endpoint), new DefaultAzureCredential(), new AgentReference($"model:{deploymentName}"));
+
+ChatClientAgent agent = new(
+    chatClient: projectResponsesClient.AsIChatClient(),
+    instructions: "You are good at telling jokes.",
+    name: "JokerAgent");
+```
+
+This path is code-first and does not create a persistent server-side agent.
+
+### Versioned agent path
+
+Use the convenience overloads on `AIProjectClient`:
+
+```csharp
+AIProjectClient aiProjectClient = new(new Uri(endpoint), credential);
+
+AgentVersion version = await aiProjectClient.Agents.CreateAgentVersionAsync(
+    "JokerAgent",
+    new AgentVersionCreationOptions(
+        new PromptAgentDefinition(deploymentName)
+        {
+            Instructions = "You are good at telling jokes."
+        }));
+
+ChatClientAgent agent = aiProjectClient.AsAIAgent(version);
+```
+
+Or use composed `ChatClientAgent`
+
+```csharp
+AIProjectClient aiProjectClient = new(new Uri(endpoint), credential);
+
+AgentVersion version = await aiProjectClient.Agents.CreateAgentVersionAsync(
+    "JokerAgent",
+    new AgentVersionCreationOptions(
+        new PromptAgentDefinition(deploymentName)
+        {
+            Instructions = "You are good at telling jokes."
+        }));
+
+ProjectResponsesClient projectResponsesClient = aiProjectClient
+    .GetProjectOpenAIClient()
+    .GetProjectResponsesClientForAgent(new AgentReference(version.Name, version.Version));
+
+ChatClientAgent agent = new(
+    chatClient: projectResponsesClient.AsIChatClient(),
+    name: "JokerAgent");
+```
+
+### Samples
+
+- `FoundryAgents/` samples show the direct Responses path with `AIProjectClient.AsAIAgent(...)`.
+- `FoundryVersionedAgents/` samples should show native `AIProjectClient.Agents` create/get/delete flows plus `AsAIAgent(...)`.
+
+### Compatibility APIs
+
+Obsolete helper extensions remain only to ease migration of existing code. New samples and new guidance should not be written against them.
+
+## Rejected direction
+
+Do not introduce or preserve separate public wrapper types whose main purpose is to forward to `ChatClientAgent` while carrying Foundry-specific naming.
+
+That approach:
+
+- duplicates lifecycle concepts already present on `AIProjectClient`,
+- fragments the public API,
+- complicates samples and docs,
+- and makes migration harder by encouraging wrapper-specific affordances.

+# Agent Skills: Multi-Source Architecture
+
+## Context and Problem Statement
+
+The Agent Framework needs a skills system that lets agents discover and use domain-specific knowledge, reference documents, and executable scripts. Skills can originate from different sources — filesystem directories (SKILL.md files), inline C# code, or reusable class libraries — and the framework must support all three uniformly while allowing extensibility, composition, and filtering.
+
+## Decision Drivers
+
+- Skills must be definable from multiple sources: filesystem, inline code, reusable classes, etc
+- Common abstractions are needed so the provider and builder work uniformly regardless of skill origin
+- File-based scripts must support user-defined executors, enabling custom runtimes and languages; code/class-based scripts execute in-process as C# delegates
+- Skills must be filterable so consumers can include or exclude specific skills based on defined criteria
+- Multiple skill sources must be composable into a single provider
+- It must be possible to add custom skill sources (e.g., databases, REST APIs, package registries) by implementing a common abstraction
+
+## Architecture
+
+### Model-Facing Tools
+
+Skills are presented to the model as up to three tools that progressively disclose skill content. The system prompt lists available skill names and descriptions; the model then calls these tools on demand:
+
+- **`load_skill(skillName)`** — returns the full skill body (instructions, listed resources, listed scripts)
+- **`read_skill_resource(skillName, resourceName)`** — reads a supplementary resource (file-based or code-defined) associated with a skill
+- **`run_skill_script(skillName, scriptName, arguments?)`** — executes a script associated with a skill; only registered when at least one skill contains scripts
+
+Each tool delegates to the corresponding method on the resolved `AgentSkill` — calling `Resource.ReadAsync()` or `Script.RunAsync()` respectively.
+
+If skills have no scripts defined, the `run_skill_script` tool is **not advertised** to the model and instructions related to script execution are **not included** in the default skills instructions.
+
+### Abstract Base Types
+
+The architecture defines four abstract base types that all skill variants implement:
+
+```csharp
+public abstract class AgentSkill
+{
+    public abstract AgentSkillFrontmatter Frontmatter { get; }
+    public abstract string Content { get; }
+    public abstract IReadOnlyList<AgentSkillResource>? Resources { get; }
+    public abstract IReadOnlyList<AgentSkillScript>? Scripts { get; }
+}
+
+public abstract class AgentSkillResource
+{
+    public string Name { get; }
+    public string? Description { get; }
+    public abstract Task<object?> ReadAsync(IServiceProvider? serviceProvider = null, CancellationToken cancellationToken = default);
+}
+
+public abstract class AgentSkillScript
+{
+    public string Name { get; }
+    public string? Description { get; }
+    public abstract Task<object?> RunAsync(AgentSkill skill, AIFunctionArguments arguments, CancellationToken cancellationToken = default);
+}
+
+public abstract class AgentSkillsSource
+{
+    public abstract Task<IList<AgentSkill>> GetSkillsAsync(CancellationToken cancellationToken = default);
+}
+```
+
+Skill metadata is captured via `AgentSkillFrontmatter`:
+
+```csharp
+public sealed class AgentSkillFrontmatter
+{
+    public AgentSkillFrontmatter(string name, string description) { ... }
+
+    public string Name { get; }
+    public string Description { get; }
+    public string? License { get; set; }
+    public string? Compatibility { get; set; }
+    public string? AllowedTools { get; set; }
+    public AdditionalPropertiesDictionary? Metadata { get; set; }
+}
+```
+
+The type hierarchy at a glance:
+
+```
+AgentSkill (abstract)                   AgentSkillsSource (abstract)
+├── AgentFileSkill                      ├── AgentFileSkillsSource          (public)

+                                        └── AgentInlineSkillScript
+```
+
+There are two top-level categories of skills:
+
+1. **File-Based Skills** — discovered from `SKILL.md` files on the filesystem. Resources and scripts are files in subdirectories.
+2. **Programmatic Skills** — defined in C# code. These are further divided into:
+   - **Inline Skills** — built at runtime via the `AgentInlineSkill` class and its fluent API. Ideal for quick, agent-specific skill definitions.
+   - **Class-Based Skills** — defined as reusable C# classes that subclass `AgentClassSkill`. Ideal for packaging skills as shared libraries or NuGet packages.
+
+Both programmatic skill types use `AgentInlineSkillResource` and `AgentInlineSkillScript` for their resources and scripts. They are typically served by `AgentInMemorySkillsSource`, which accepts any `AgentSkill` and is not limited to programmatic skills.
+
+### File-Based Skills
+
+File-based skills are authored as `SKILL.md` files on disk. Resources and scripts are discovered from corresponding subfolders within the skill directory.
+
+**`AgentFileSkill`** — A filesystem-based skill discovered from a directory containing a `SKILL.md` file. Parsed from YAML frontmatter; content is the raw markdown body. Resources and scripts are discovered from files in corresponding subfolders:
+
+```csharp
+public sealed class AgentFileSkill : AgentSkill
+{
+    internal AgentFileSkill(
+        AgentSkillFrontmatter frontmatter, string content, string path,
+        IReadOnlyList<AgentSkillResource>? resources = null,
+        IReadOnlyList<AgentSkillScript>? scripts = null) { ... }
+}
+```
+
+**`AgentFileSkillResource`** — A file-based skill resource. Reads content from a file on disk relative to the skill directory:
+
+```csharp
+internal sealed class AgentFileSkillResource : AgentSkillResource
+{
+    public AgentFileSkillResource(string name, string fullPath) { ... }
+
+    public string FullPath { get; }
+
+    public override Task<object?> ReadAsync(IServiceProvider? serviceProvider = null, CancellationToken cancellationToken = default)
+    {
+        return File.ReadAllTextAsync(FullPath, Encoding.UTF8, cancellationToken);
+    }
+}
+```
+
+**`AgentFileSkillScript`** — A file-based skill script that represents a script file on disk. Delegates execution to an external `AgentFileSkillScriptRunner` callback (e.g., runs Python/shell via `Process.Start`). Throws `NotSupportedException` if no executor is configured:
+
+```csharp
+public delegate Task<object?> AgentFileSkillScriptRunner(
+    AgentFileSkill skill, AgentFileSkillScript script,
+    AIFunctionArguments arguments, CancellationToken cancellationToken);
+
+public sealed class AgentFileSkillScript : AgentSkillScript
+{
+    private readonly AgentFileSkillScriptRunner _executor;
+
+    internal AgentFileSkillScript(string name, string fullPath, AgentFileSkillScriptRunner executor)
+        : base(name) { ... }
+
+    public override async Task<object?> RunAsync(AgentSkill skill, AIFunctionArguments arguments, ...)
+    {
+
+        return await _executor(fileSkill, this, arguments, cancellationToken);
+    }
+}
+```
+
+The executor can be provided at the **provider level** via `AgentSkillsProviderBuilder.UseFileScriptRunner(executor)` and optionally overridden for a **particular file skill** or for a **set of skills** at the file skill source level, giving fine-grained control over how different scripts are executed.
+
+**`AgentFileSkillsSource`** — A skill source that discovers skills from filesystem directories containing `SKILL.md` files. Recursively scans directories (max 2 levels), validates frontmatter, and enforces path traversal and symlink security checks:
+
+```csharp
+public sealed partial class AgentFileSkillsSource : AgentSkillsSource
+{
+    public AgentFileSkillsSource(
+        IEnumerable<string> skillPaths,
+        AgentFileSkillScriptRunner scriptRunner,
+        AgentFileSkillsSourceOptions? options = null,
+        ILoggerFactory? loggerFactory = null) { ... }
+}
+```
+
+**`AgentFileSkillsSourceOptions`** — Configuration options for `AgentFileSkillsSource`. Allows customizing the allowed file extensions for resources and scripts without adding constructor parameters:
+
+```csharp
+public sealed class AgentFileSkillsSourceOptions
+{
+    public IEnumerable<string>? AllowedResourceExtensions { get; set; }
+    public IEnumerable<string>? AllowedScriptExtensions { get; set; }
+}
+```
+
+**Example** — A file-based skill on disk and how it is added to a source:
+
+```
+skills/
+└── unit-converter/
+    ├── SKILL.md               # frontmatter + instructions
+    ├── resources/
+    │   └── conversion-table.csv   # discovered as a resource
+    └── scripts/
+        └── convert.py             # discovered as a script
+```
+
+```csharp
+var source = new AgentFileSkillsSource(skillPaths: ["./skills"], scriptRunner: SubprocessScriptRunner.RunAsync);
+
+var provider = new AgentSkillsProvider(source);
+
+AIAgent agent = chatClient.AsAIAgent(new ChatClientAgentOptions
+{
+    AIContextProviders = [provider],
+});
+```
+
+### Programmatic Skills
+
+Programmatic skills are defined in C# code rather than discovered from the filesystem. There are two kinds: **inline** and **class-based**. Both use `AgentInlineSkillResource` and `AgentInlineSkillScript` for resources and scripts, and are held by a single `AgentInMemorySkillsSource`.
+
+**`AgentInMemorySkillsSource`** — A general-purpose skill source that holds any `AgentSkill` instances in memory. Although commonly used for programmatic skills (`AgentInlineSkill` and `AgentClassSkill`), it accepts any `AgentSkill` subclass and is not restricted to code-defined skills:
+
+```csharp
+public sealed class AgentInMemorySkillsSource : AgentSkillsSource
+{
+    public AgentInMemorySkillsSource(
+        IEnumerable<AgentSkill> skills,
+        ILoggerFactory? loggerFactory = null) { ... }
+}
+```
+
+#### Inline Skills
+
+Inline skills are built at runtime via the `AgentInlineSkill` class and its fluent API. They are ideal for quick, agent-specific skill definitions where a full class hierarchy would be overkill.
+
+**`AgentInlineSkill`** — A skill defined entirely in code. Resources can be static values or functions; scripts are always functions. Constructed with name, description, and instructions, then extended with resources and scripts:
+
+```csharp
+public sealed class AgentInlineSkill : AgentSkill
+{
+    public AgentInlineSkill(string name, string description, string instructions, string? license = null, string? compatibility = null, ...) { ... }
+    public AgentInlineSkill(AgentSkillFrontmatter frontmatter, string instructions) { ... }
+
+    public AgentInlineSkill AddResource(object value, string name, string? description = null);
+    public AgentInlineSkill AddResource(Delegate handler, string name, string? description = null);
+    public AgentInlineSkill AddScript(Delegate handler, string name, string? description = null);
+}
+```
+
+**`AgentInlineSkillResource`** — A skill resource that wraps a static value:
+
+```csharp
+public sealed class AgentInlineSkillResource : AgentSkillResource
+{
+    public AgentInlineSkillResource(object value, string name, string? description = null)
+        : base(name, description)
+    {
+        _value = value;
+    }
+
+    public override Task<object?> ReadAsync(IServiceProvider? serviceProvider = null, CancellationToken cancellationToken = default)
+    {
+        return Task.FromResult<object?>(_value);
+    }
+}
+```
+
+**`AgentInlineSkillResource`** — A skill resource backed by a delegate. The delegate is invoked via an `AIFunction` each time `ReadAsync` is called, producing a dynamic (computed) value:
+
+```csharp
+public sealed class AgentInlineSkillResource : AgentSkillResource
+{
+    public AgentInlineSkillResource(Delegate handler, string name, string? description = null)
+        : base(name, description)
+    {
+        _function = AIFunctionFactory.Create(handler, name: name);
+    }
+
+    public override async Task<object?> ReadAsync(IServiceProvider? serviceProvider = null, CancellationToken cancellationToken = default)
+    {
+        return await _function.InvokeAsync(new AIFunctionArguments() { Services = serviceProvider }, cancellationToken);
+    }
+}
+```
+
+**`AgentInlineSkillScript`** — A skill script backed by a delegate via an `AIFunction`:
+
+```csharp
+public sealed class AgentInlineSkillScript : AgentSkillScript
+{
+    private readonly AIFunction _function;
+
+    public AgentInlineSkillScript(Delegate handler, string name, string? description = null)
+        : base(name, description)
+    {
+        _function = AIFunctionFactory.Create(handler, name: name);
+    }
+
+    public JsonElement? ParametersSchema => _function.JsonSchema;
+
+    public override async Task<object?> RunAsync(AgentSkill skill, AIFunctionArguments arguments, ...)
+    {
+        return await _function.InvokeAsync(arguments, cancellationToken);
+    }
+}
+```
+
+**Example** — Creating an inline skill with a resource and script, then adding it to a source:
+
+```csharp
+var skill = new AgentInlineSkill(
+        name: "unit-converter",
+        description: "Converts between measurement units.",
+        instructions: """
+            Use this skill to convert values between metric and imperial units.
+            Refer to the conversion-table resource for supported unit pairs.
+            Run the convert script to perform conversions.
+            """
+    )
+    .AddResource("kg=2.205lb, m=3.281ft, L=0.264gal", "conversion-table", "Supported unit pairs")
+    .AddScript(Convert, "convert", "Converts a value between units");
+
+var source = new AgentInMemorySkillsSource([skill]);
+
+var provider = new AgentSkillsProvider(source);
+
+AIAgent agent = chatClient.AsAIAgent(new ChatClientAgentOptions
+{
+    AIContextProviders = [provider],
+});
+
+static string Convert(double value, double factor)
+    => JsonSerializer.Serialize(new { result = Math.Round(value * factor, 4) });
+```
+
+#### Class-Based Skills
+
+Class-based skills are designed for packaging skills as reusable libraries. Users subclass `AgentClassSkill` and override properties. Unlike inline skills, class-based skills are self-contained, can live in shared libraries or NuGet packages, and are well-suited for dependency injection.
+
+**`AgentClassSkill`** — An abstract base class for defining skills as reusable C# classes that bundle all skill components (frontmatter, instructions, resources, scripts) together. Designed for packaging skills as distributable libraries:
+
+```csharp
+public abstract class AgentClassSkill : AgentSkill
+{
+    public abstract string Instructions { get; }
+
+    // Content is auto-synthesized from Frontmatter + Instructions + Resources + Scripts
+    public override string Content =>
+        SkillContentBuilder.BuildContent(Frontmatter.Name, Frontmatter.Description,
+            SkillContentBuilder.BuildBody(Instructions, Resources, Scripts));
+}
+```
+
+**Example** — Defining a class-based skill and adding it to a source:
+
+```csharp
+public class UnitConverterSkill : AgentClassSkill
+{
+    public override AgentSkillFrontmatter Frontmatter { get; } =
+        new("unit-converter", "Converts between measurement units.");
+
+    public override string Instructions => """
+        Use this skill to convert values between metric and imperial units.
+        Refer to the conversion-table resource for supported unit pairs.
+        Run the convert script to perform conversions.
+        """;
+
+    public override IReadOnlyList<AgentSkillResource>? Resources { get; } =
+    [
+        new AgentInlineSkillResource("kg=2.205lb, m=3.281ft", "conversion-table"),
+    ];
+
+    public override IReadOnlyList<AgentSkillScript>? Scripts { get; } =
+    [
+        new AgentInlineSkillScript(Convert, "convert"),
+    ];
+
+    private static string Convert(double value, double factor)
+        => JsonSerializer.Serialize(new { result = Math.Round(value * factor, 4) });
+}
+
+var source = new AgentInMemorySkillsSource([new UnitConverterSkill()]);
+
+var provider = new AgentSkillsProvider(source);
+
+AIAgent agent = chatClient.AsAIAgent(new ChatClientAgentOptions
+{
+    AIContextProviders = [provider],
+});
+```
+
+## Filtering, Caching, and Deduplication
+
+The following subsections present alternative approaches for handling filtering, caching, and deduplication of skills across multiple sources.
+
+### Via Composition
+
+In this approach, the `AgentSkillsProvider` accepts a **single** `AgentSkillsSource`. Multiple sources are composed externally via an aggregate source, and cross-cutting concerns like filtering, caching, and deduplication are implemented as **source decorators** — subclasses of `DelegatingAgentSkillsSource` that intercept `GetSkillsAsync()`.
+
+**`FilteringAgentSkillsSource`** — A decorator that applies filter logic before returning results. The decorator pattern keeps filtering orthogonal to source implementations and allows composing multiple filters:
+
+```csharp
+public sealed class FilteringAgentSkillsSource : DelegatingAgentSkillsSource
+{
+    private readonly Func<AgentSkill, bool> _predicate;
+
+    public FilteringAgentSkillsSource(AgentSkillsSource innerSource, Func<AgentSkill, bool> predicate)
+        : base(innerSource)
+    {
+        _predicate = predicate;
+    }
+
+    public override async Task<IList<AgentSkill>> GetSkillsAsync(CancellationToken cancellationToken = default)
+    {
+        var skills = await this.InnerSource.GetSkillsAsync(cancellationToken);
+        return skills.Where(_predicate).ToList();
+    }
+}
+```
+
+**`CachingAgentSkillsSource`** — A decorator that caches skills after the first load, keeping the provider stateless and giving consumers control over caching granularity per source. For example, file-based skills (expensive to discover) can be cached while code-defined skills remain uncached:
+
+```csharp
+public sealed class CachingAgentSkillsSource : DelegatingAgentSkillsSource
+{
+    private IList<AgentSkill>? _cached;
+
+    public CachingAgentSkillsSource(AgentSkillsSource innerSource)
+        : base(innerSource)
+    {
+    }
+
+    public override async Task<IList<AgentSkill>> GetSkillsAsync(CancellationToken cancellationToken = default)
+    {
+        return _cached ??= await this.InnerSource.GetSkillsAsync(cancellationToken);
+    }
+}
+```
+
+**Deduplication** is similarly implemented as a decorator (`DeduplicatingAgentSkillsSource`) that deduplicates by name (case-insensitive, first-one-wins) and logs a warning for skipped duplicates.
+
+**Example** — Combining file-based and code-defined sources with filtering and caching:
+
+```csharp
+var fileSource = new CachingAgentSkillsSource(new AgentFileSkillsSource(["./skills"]));
+var codeSource = new AgentInMemorySkillsSource([myCodeSkill]);
+
+var compositeSource = new FilteringAgentSkillsSource(
+    new AggregatingAgentSkillsSource([fileSource, codeSource]),
+    filter: s => s.Frontmatter.Name != "internal");
+
+var provider = new AgentSkillsProvider(compositeSource);
+
+AIAgent agent = chatClient.AsAIAgent(new ChatClientAgentOptions
+{
+    AIContextProviders = [provider],
+});
+```
+
+**Pros:**
+- Clean single-responsibility: the provider serves skills, sources provide them.
+- Caching, filtering, and deduplication are composable as source decorators — each concern is a separate, testable wrapper.
+
+**Cons:**
+- DI is less flexible: multiple `AgentSkillsSource` implementations registered in the container cannot be auto-injected into the provider. The consumer must manually compose them via an aggregate source.
+- Increased public API surface: requires additional public classes (aggregate source, caching decorators, filtering decorators) that consumers need to learn and use.
+
+### Via AgentSkillsProvider
+
+In this approach, the `AgentSkillsProvider` accepts **`IEnumerable<AgentSkillsSource>`** and handles aggregation, filtering, caching, and deduplication internally.
+
+The provider aggregates skills from all registered sources, deduplicates by name (case-insensitive, first-one-wins), caches the result after the first load, and optionally applies filtering via a predicate on `AgentSkillsProviderOptions`. Duplicate skill names are logged as warnings.
+
+**Example** — Registering multiple sources directly with the provider:
+
+```csharp
+// Conceptual example — in practice, use AgentSkillsProviderBuilder
+var fileSource = new AgentFileSkillsSource(["./skills"]);
+var codeSource = new AgentInMemorySkillsSource([myCodeSkill]);
+
+var provider = new AgentSkillsProvider(
+    sources: [fileSource, codeSource],
+    options: new AgentSkillsProviderOptions
+    {
+        Filter = s => s.Frontmatter.Name != "internal",
+    });
+
+AIAgent agent = chatClient.AsAIAgent(new ChatClientAgentOptions
+{
+    AIContextProviders = [provider],
+});
+```
+
+**Pros:**
+- DI-friendly: register multiple `AgentSkillsSource` implementations in the container, and they are all auto-injected into `AgentSkillsProvider` via `IEnumerable<AgentSkillsSource>`.
+- Smaller public API surface: no need for aggregate source, caching decorators, or filtering decorator classes — these concerns are handled internally by the provider.
+
+**Cons:**
+- The provider takes on multiple responsibilities — aggregation, caching, deduplication, and filtering.
+- Less granular caching control: caching is all-or-nothing across sources rather than per-source as with decorators.
+- Less extensible: new behaviors (e.g., ordering, TTL expiration) require modifying the provider rather than adding a decorator.
+
+### Builder Pattern
+
+**`AgentSkillsProviderBuilder`** provides a fluent API for composing skills from multiple sources. The builder centralizes configuration — script executors, approval callbacks, prompt templates, and filtering — so consumers don't need to know the underlying source types.
+
+The builder internally decides how to wire up the object graph: it creates the appropriate source instances, applies caching and filtering, and returns a fully configured `AgentSkillsProvider`. This keeps the setup code concise while still allowing fine-grained control when needed.
+
+**Example** — Using the builder to combine multiple source types with configuration:
+
+```csharp
+var provider = new AgentSkillsProviderBuilder()
+    .UseFileSkill("./skills")                           // file-based source
+    .UseInlineSkills(codeSkill)                            // code-defined source
+    .UseClassSkills(new ClassSkill())                    // class-based source
+    .UseFileScriptRunner(SubprocessScriptRunner.RunAsync) // script runner
+    .UseScriptApproval()                                // optional human-in-the-loop
+    .UsePromptTemplate(customTemplate)                  // optional prompt customization
+    .UseFilter(s => s.Frontmatter.Name != "internal")   // optional skill filtering
+    .Build();
+
+AIAgent agent = chatClient.AsAIAgent(new ChatClientAgentOptions
+{
+    AIContextProviders = [provider],
+});
+```
+
+## Adding a Custom Skill Type
+
+The skills framework is designed for extensibility. While file-based and inline skills cover common
+scenarios, you can introduce entirely new skill types by subclassing the four base classes:
+
+| Base class            | Purpose                                             |
+|-----------------------|-----------------------------------------------------|
+| `AgentSkillsSource`   | Discovers and loads skills from a particular origin  |
+| `AgentSkill`          | Holds metadata, content, resources, and scripts      |
+| `AgentSkillResource`  | Provides supplementary content to a skill            |
+| `AgentSkillScript`    | Represents an executable action within a skill       |
+
+The example below implements a **cloud-based skill type** where skills, resources, and scripts are
+all stored in and executed through a remote cloud service (e.g., Azure Blob Storage + Azure Functions).
+
+### Step 1 — Define a custom resource
+
+A `CloudSkillResource` reads resource content from a cloud storage endpoint instead of the local
+filesystem:
+
+```csharp
+/// <summary>
+/// A skill resource backed by a cloud storage endpoint.
+/// </summary>
+public sealed class CloudSkillResource : AgentSkillResource
+{
+    private readonly HttpClient _httpClient;
+
+    public CloudSkillResource(string name, Uri blobUri, HttpClient httpClient, string? description = null)
+        : base(name, description)
+    {
+        BlobUri = blobUri ?? throw new ArgumentNullException(nameof(blobUri));
+        _httpClient = httpClient ?? throw new ArgumentNullException(nameof(httpClient));
+    }
+
+    /// <summary>
+    /// Gets the URI of the cloud blob that holds this resource's content.
+    /// </summary>
+    public Uri BlobUri { get; }
+
+    /// <inheritdoc/>
+    public override async Task<object?> ReadAsync(
+        IServiceProvider? serviceProvider = null,
+        CancellationToken cancellationToken = default)
+    {
+        return await _httpClient.GetStringAsync(BlobUri, cancellationToken).ConfigureAwait(false);
+    }
+}
+```
+
+### Step 2 — Define a custom script
+
+A `CloudSkillScript` executes a script by calling a cloud function endpoint, passing arguments as
+the request body:
+
+```csharp
+/// <summary>
+/// A skill script executed via a cloud function endpoint.
+/// </summary>
+public sealed class CloudSkillScript : AgentSkillScript
+{
+    private readonly HttpClient _httpClient;
+
+    public CloudSkillScript(string name, Uri functionUri, HttpClient httpClient, string? description = null)
+        : base(name, description)
+    {
+        FunctionUri = functionUri ?? throw new ArgumentNullException(nameof(functionUri));
+        _httpClient = httpClient ?? throw new ArgumentNullException(nameof(httpClient));
+    }
+
+    /// <summary>
+    /// Gets the URI of the cloud function that runs this script.
+    /// </summary>
+    public Uri FunctionUri { get; }
+
+    /// <inheritdoc/>
+    public override async Task<object?> RunAsync(
+        AgentSkill skill,
+        AIFunctionArguments arguments,
+        CancellationToken cancellationToken = default)
+    {
+        var json = JsonSerializer.Serialize(arguments);
+        using var content = new StringContent(json, Encoding.UTF8, "application/json");
+        var response = await _httpClient.PostAsync(FunctionUri, content, cancellationToken)
+            .ConfigureAwait(false);
+        response.EnsureSuccessStatusCode();
+        return await response.Content.ReadAsStringAsync(cancellationToken).ConfigureAwait(false);
+    }
+}
+```
+
+### Step 3 — Define a custom skill
+
+A `CloudSkill` bundles cloud-specific metadata (e.g., the base endpoint) with the standard skill
+shape:
+
+```csharp
+/// <summary>
+/// An <see cref="AgentSkill"/> whose content, resources, and scripts are stored in a cloud service.
+/// </summary>
+public sealed class CloudSkill : AgentSkill
+{
+    public CloudSkill(
+        AgentSkillFrontmatter frontmatter,
+        string content,
+        Uri endpoint,
+        IReadOnlyList<AgentSkillResource>? resources = null,
+        IReadOnlyList<AgentSkillScript>? scripts = null)
+    {
+        Frontmatter = frontmatter ?? throw new ArgumentNullException(nameof(frontmatter));
+        Content = content ?? throw new ArgumentNullException(nameof(content));
+        Endpoint = endpoint ?? throw new ArgumentNullException(nameof(endpoint));
+        Resources = resources;
+        Scripts = scripts;
+    }
+
+    /// <inheritdoc/>
+    public override AgentSkillFrontmatter Frontmatter { get; }
+
+    /// <inheritdoc/>
+    public override string Content { get; }
+
+    /// <summary>
+    /// Gets the base cloud endpoint for this skill.
+    /// </summary>
+    public Uri Endpoint { get; }
+
+    /// <inheritdoc/>
+    public override IReadOnlyList<AgentSkillResource>? Resources { get; }
+
+    /// <inheritdoc/>
+    public override IReadOnlyList<AgentSkillScript>? Scripts { get; }
+}
+```
+
+### Step 4 — Define a custom source
+
+A `CloudSkillsSource` discovers skills from a cloud catalog API and constructs `CloudSkill`
+instances with their associated resources and scripts:
+
+```csharp
+/// <summary>
+/// A skill source that discovers and loads skills from a cloud catalog API.
+/// </summary>
+public sealed class CloudSkillsSource : AgentSkillsSource
+{
+    private readonly Uri _catalogUri;
+    private readonly HttpClient _httpClient;
+
+    public CloudSkillsSource(Uri catalogUri, HttpClient httpClient)
+    {
+        _catalogUri = catalogUri ?? throw new ArgumentNullException(nameof(catalogUri));
+        _httpClient = httpClient ?? throw new ArgumentNullException(nameof(httpClient));
+    }
+
+    /// <inheritdoc/>
+    public override async Task<IList<AgentSkill>> GetSkillsAsync(
+        CancellationToken cancellationToken = default)
+    {
+        // Fetch the skill catalog from the cloud service.
+        var json = await _httpClient.GetStringAsync(_catalogUri, cancellationToken)
+            .ConfigureAwait(false);
+        var catalog = JsonSerializer.Deserialize<CloudSkillCatalog>(json)!;
+
+        var skills = new List<AgentSkill>();
+
+        foreach (var entry in catalog.Skills)
+        {
+            var frontmatter = new AgentSkillFrontmatter(entry.Name, entry.Description);
+
+            // Build cloud-backed resources.
+            var resources = entry.Resources
+                .Select(r => new CloudSkillResource(r.Name, r.BlobUri, _httpClient, r.Description))
+                .ToList<AgentSkillResource>();
+
+            // Build cloud-backed scripts.
+            var scripts = entry.Scripts
+                .Select(s => new CloudSkillScript(s.Name, s.FunctionUri, _httpClient, s.Description))
+                .ToList<AgentSkillScript>();
+
+            skills.Add(new CloudSkill(frontmatter, entry.Content, entry.Endpoint, resources, scripts));
+        }
+
+        return skills;
+    }
+}
+```
+
+### Step 5 — Register with the builder
+
+Use `UseSource` to wire the custom source into the provider:
+
+```csharp
+var httpClient = new HttpClient();
+
+var provider = new AgentSkillsProviderBuilder()
+    .UseSource(new CloudSkillsSource(
+        new Uri("https://my-service.example.com/skills/catalog"),
+        httpClient))
+    // Mix with other source types if needed:
+    .UseFileSkill("/local/skills", scriptRunner)
+    .UseInlineSkills(someInlineSkill)
+    .Build();
+```
+
+The `AgentSkillsProvider` handles all skill types uniformly — any combination of file-based, inline,
+class-based, and custom skills can coexist in the same provider. Custom skills automatically
+participate in the model-facing tools (`load_skill`, `read_skill_resource`, `run_skill_script`),
+filtering, deduplication, and caching — no additional integration work is required.
+
+## Script Representation: `AgentSkillScript` vs `AIFunction`
+
+Two approaches were considered for representing executable scripts within skills:
+
+### Option A — Custom `AgentSkillScript` abstract base class (original design)
+
+Scripts are modeled as a custom `AgentSkillScript` abstract class with `Name`, `Description`, and
+`RunAsync(AgentSkill, AIFunctionArguments, CancellationToken)`. Concrete implementations:
+`AgentInlineSkillScript` (wraps a delegate/`AIFunction`) and `AgentFileSkillScript` (wraps a file path + executor delegate).
+
+```csharp
+// Base type
+public abstract class AgentSkillScript
+{
+    public string Name { get; }
+    public string? Description { get; }
+    public abstract Task<object?> RunAsync(AgentSkill skill, AIFunctionArguments arguments, CancellationToken cancellationToken = default);
+}
+
+// AgentSkill exposes scripts as:
+public abstract IReadOnlyList<AgentSkillScript>? Scripts { get; }
+
+// Inline script wraps an AIFunction internally
+var script = new AgentInlineSkillScript(ConvertUnits, "convert");
+
+// Pre-built AIFunction must be wrapped
+var script = new AgentInlineSkillScript(myAIFunction);
+
+// Class-based skill declares scripts as:
+public override IReadOnlyList<AgentSkillScript>? Scripts { get; } =
+[
+    new AgentInlineSkillScript(ConvertUnits, "convert"),
+];
+
+// Provider executes scripts by passing the owning skill:
+await script.RunAsync(skill, arguments, cancellationToken);
+```
+
+**Pros:**
+
+- **Explicit skill context at execution time.** `RunAsync` receives the owning `AgentSkill`, so any script can access skill metadata or resources during execution without requiring construction-time wiring.
+- **Self-contained abstraction.** A dedicated type communicates clearly that scripts are a skills-framework concept, separate from general-purpose AI functions.
+- **Easier extensibility for custom script types.** Third-party implementations can subclass `AgentSkillScript` and access the owning skill in `RunAsync` without special setup.
+
+**Cons:**
+
+- **Wrapper overhead.** `AgentInlineSkillScript` is a thin pass-through around `AIFunction` — it adds a class, a constructor, and an indirection layer for no behavioral difference.
+- **Parallel abstraction.** `AgentSkillScript` and `AIFunction` serve overlapping purposes (named callable with arguments), creating two parallel hierarchies for the same concept.
+- **Friction for consumers.** Users who already have `AIFunction` instances must wrap them in `AgentInlineSkillScript` to use them as scripts, adding ceremony.
+
+### Option B — Reuse `AIFunction` directly
+
+Scripts are represented as `AIFunction` (from `Microsoft.Extensions.AI`). `AgentSkill.Scripts` returns
+`IReadOnlyList<AIFunction>?`. `AgentInlineSkillScript` is eliminated entirely — callers use
+`AIFunctionFactory.Create(delegate, name: ...)` or pass `AIFunction` instances directly.
+`AgentFileSkillScript` becomes an `AIFunction` subclass that captures its owning `AgentFileSkill` via
+an internal back-reference set during construction.
+
+```csharp
+// AgentSkill exposes scripts as AIFunction directly:
+public abstract IReadOnlyList<AIFunction>? Scripts { get; }
+
+// Inline scripts use AIFunctionFactory — no wrapper class needed
+var skill = new AgentInlineSkill("my-skill", "desc", "instructions");
+skill.AddScript(ConvertUnits, "convert");           // delegate
+skill.AddScript(myAIFunction);                       // pre-built AIFunction — no wrapping
+
+// Class-based skill declares scripts as:
+public override IReadOnlyList<AIFunction>? Scripts { get; } =
+[
+    AIFunctionFactory.Create(ConvertUnits, name: "convert"),
+];
+
+// Provider executes scripts via standard AIFunction invocation:
+await script.InvokeAsync(arguments, cancellationToken);
+
+// File-based scripts extend AIFunction and capture the owning skill internally:
+public sealed class AgentFileSkillScript : AIFunction
+{
+    internal AgentFileSkill? Skill { get; set; }   // set by AgentFileSkill constructor
+
+    protected override async ValueTask<object?> InvokeCoreAsync(
+        AIFunctionArguments arguments, CancellationToken cancellationToken)
+    {
+        return await _executor(Skill!, this, arguments, cancellationToken);
+    }
+}
+```
+
+**Pros:**
+
+- **Fewer types.** Eliminates `AgentSkillScript` and `AgentInlineSkillScript`, reducing the public API surface by two classes.
+- **Seamless interop.** Any `AIFunction` — whether from `AIFunctionFactory`, a custom subclass, or an external library — can be used as a skill script with zero wrapping.
+- **Consistent with `Microsoft.Extensions.AI` ecosystem.** Scripts share the same type as tool functions used by `IChatClient` and `FunctionInvokingChatClient`, reducing conceptual overhead for developers already familiar with the ecosystem.
+
+**Cons:**
+
+- **No owning-skill context in invocation signature.** `AIFunction.InvokeAsync` does not accept an `AgentSkill` parameter, so `AgentFileSkillScript` must capture its owning skill via an internal setter during construction. This adds a construction-order dependency: the skill must set the back-reference on its scripts.
+- **Custom script types lose automatic skill access.** Third-party `AIFunction` subclasses that need the owning skill must implement their own mechanism (e.g., constructor injection, closure capture) instead of receiving it as a method parameter.
+- **Semantic overloading.** `AIFunction` now means both "a tool the model can call" and "a script within a skill", which could blur the distinction for framework users.
+
+## Resource Representation: `AgentSkillResource` vs `AIFunction`
+
+Two approaches were considered for representing skill resources (supplementary content such as references, assets, or dynamic data):
+
+### Option A — Custom `AgentSkillResource` abstract base class (original design)
+
+Resources are modeled as a custom `AgentSkillResource` abstract class with `Name`, `Description`, and
+`ReadAsync(IServiceProvider?, CancellationToken)`. Concrete implementations:
+`AgentInlineSkillResource` (static value, delegate, or `AIFunction` wrapper) and `AgentFileSkillResource` (reads file content from disk).
+
+```csharp
+// Base type
+public abstract class AgentSkillResource
+{
+    public string Name { get; }
+    public string? Description { get; }
+    public abstract Task<object?> ReadAsync(IServiceProvider? serviceProvider = null, CancellationToken cancellationToken = default);
+}
+
+// AgentSkill exposes resources as:
+public abstract IReadOnlyList<AgentSkillResource>? Resources { get; }
+
+// Static resource
+var resource = new AgentInlineSkillResource("static content", "my-resource");
+
+// Dynamic resource (delegate)
+var resource = new AgentInlineSkillResource((IServiceProvider sp) => GetData(sp), "my-resource");
+
+// Pre-built AIFunction must be wrapped
+var resource = new AgentInlineSkillResource(myAIFunction);
+
+// Class-based skill declares resources as:
+public override IReadOnlyList<AgentSkillResource>? Resources { get; } =
+[
+    new AgentInlineSkillResource("# Conversion Tables\n...", "conversion-table"),
+];
+
+// Provider reads resources via:
+await resource.ReadAsync(serviceProvider, cancellationToken);
+```
+
+**Pros:**
+
+- **Clear semantic distinction.** A dedicated `AgentSkillResource` type distinguishes resources (data providers) from scripts (executable actions), making the API self-documenting.
+- **Purpose-built API.** `ReadAsync` communicates intent better than `InvokeAsync` for a data-access operation.
+
+**Cons:**
+
+- **Wrapper overhead.** `AgentInlineSkillResource` wraps `AIFunction` internally for delegate/function cases — adding a class and indirection for no behavioral difference.
+- **Parallel abstraction.** `AgentSkillResource` and `AIFunction` serve overlapping purposes (named callable that returns data), creating two parallel hierarchies.
+- **Friction for consumers.** Users who already have `AIFunction` instances must wrap them in `AgentInlineSkillResource`, adding ceremony.
+
+### Option B — Reuse `AIFunction` directly
+
+Resources are represented as `AIFunction`. `AgentSkill.Resources` returns `IReadOnlyList<AIFunction>?`.
+`AgentInlineSkillResource` becomes an `AIFunction` subclass (retained as a convenience for the static-value
+pattern: `new AgentInlineSkillResource("data", "name")`). `AgentFileSkillResource` becomes an `AIFunction`
+subclass that reads file content.
+
+```csharp
+// AgentSkill exposes resources as AIFunction directly:
+public abstract IReadOnlyList<AIFunction>? Resources { get; }
+
+// Static resource — AgentInlineSkillResource is retained as a convenience AIFunction subclass
+var resource = new AgentInlineSkillResource("static content", "my-resource");
+
+// Dynamic resource — AgentInlineSkillResource wraps delegate as AIFunction
+var resource = new AgentInlineSkillResource((IServiceProvider sp) => GetData(sp), "my-resource");
+
+// Pre-built AIFunction can be used directly — no wrapping needed
+skill.AddResource(myAIFunction);
+
+// Class-based skill declares resources as:
+public override IReadOnlyList<AIFunction>? Resources { get; } =
+[
+    new AgentInlineSkillResource("# Conversion Tables\n...", "conversion-table"),
+];
+
+// Provider reads resources via standard AIFunction invocation:
+await resource.InvokeAsync(arguments, cancellationToken);
+
+// File-based resources extend AIFunction directly:
+internal sealed class AgentFileSkillResource : AIFunction
+{
+    public string FullPath { get; }
+
+    protected override async ValueTask<object?> InvokeCoreAsync(
+        AIFunctionArguments arguments, CancellationToken cancellationToken)
+    {
+        return await File.ReadAllTextAsync(FullPath, Encoding.UTF8, cancellationToken);
+    }
+}
+```
+
+**Pros:**
+
+- **Fewer base types.** Eliminates the `AgentSkillResource` abstract class, reducing the public API surface.
+- **Seamless interop.** Any `AIFunction` can be used as a skill resource with zero wrapping.
+
+**Cons:**
+
+- **Loss of semantic distinction.** Resources and scripts are now both `AIFunction`, which could make it less obvious which list a function belongs to when reading code.
+- **Static values require a wrapper.** Unlike the original `ReadAsync` which could return a stored value directly, `AIFunction.InvokeAsync` implies invocation. `AgentInlineSkillResource` is retained as a convenience subclass to handle the static-value case, so this is not eliminated — just moved to a different class.
+
+## Decision Outcome
+
+### 1. Keep `AgentSkillResource` and `AgentSkillScript` (Option A for both sections)
+
+We are staying with the custom `AgentSkillResource` and `AgentSkillScript` model classes instead of reusing `AIFunction`:
+
+- **Resources have no parameters.** If a consumer provides an `AIFunction` with parameters, those parameters will never be advertised to the LLM, and the resulting call will fail.
+- **Approval breaks for `AIFunction`-based representations.** When a resource or script represented by an `AIFunction` is configured with approval, the second approval invocation will not work correctly.
+- **Injecting the owning skill into an `AIFunction`-based script is problematic.** Constructor injection would introduce a circular reference between the skill and the script. An internal property setter is possible but adds coupling.
+
+### 2. Make all agent skill classes internal
+
+All agent-skill-related classes are made `internal` to minimize the public API surface while the feature matures. We can reconsider and promote types to `public` later based on community signal.
+
+This leaves two public entry points:
+
+- **`AgentSkillsProvider`** — use directly when all skills come from a single source and filtering is not needed.
+- **`AgentSkillsProviderBuilder`** — use when mixing skill types or when filtering support is required.
+
+### 3. Caching at provider level
+
+Caching of tools and instructions is implemented inside `AgentSkillsProvider` rather than as an external decorator. Recreating tools and instructions on every provider call is wasteful, and a caching decorator sitting outside the provider would not have the information needed to cache them effectively.

+# Provider-Leading Client Design & OpenAI Package Extraction
+
+## Context and Problem Statement
+
+The `agent-framework-core` package currently bundles OpenAI and Azure OpenAI client implementations along with their dependencies (`openai`, `azure-identity`, `azure-ai-projects`, `packaging`). This makes core heavier than necessary for users who don't use OpenAI, and it conflates the core abstractions with a specific provider implementation. Additionally, the current class naming (`OpenAIResponsesClient`, `OpenAIChatClient`) is based on the underlying OpenAI API names rather than what users actually want to do, making discoverability harder for newcomers.
+
+## Decision Drivers
+
+- **Lightweight core**: Core should only contain abstractions, middleware infrastructure, and telemetry — no provider-specific code or dependencies.
+- **Discoverability-first**: Import namespaces should guide users to the right client. `from agent_framework.openai import ...` should surface all OpenAI-related clients; `from agent_framework.azure import ...` should surface Foundry, Azure AI, and other Azure-specific classes.
+- **Provider-leading naming**: The primary client name should reflect the provider, not the underlying API. The Responses API is now the recommended default for OpenAI, so its client should be called `OpenAIChatClient` (not `OpenAIResponsesClient`).
+- **Clean separation of concerns**: Azure-specific deprecated wrappers belong in the azure-ai package, not in the OpenAI package.
+
+## Considered Options
+
+- **Keep OpenAI in core**: Simpler but keeps core heavy; doesn't help discoverability.
+- **Extract OpenAI with Azure wrappers in the OpenAI package**: Keeps Azure OpenAI wrappers alongside OpenAI code, but pollutes the OpenAI package with Azure concerns.
+- **Extract OpenAI, place Azure wrappers in azure-ai**: Clean separation; the OpenAI package has zero Azure dependencies; deprecated Azure wrappers live in a single file in azure-ai for easy future deletion.
+
+## Decision Outcome
+
+Chosen option: "Extract OpenAI, place Azure wrappers in azure-ai", because it achieves the lightest core, cleanest OpenAI package, and the most maintainable deprecation path.
+
+Key changes:
+
+1. **New `agent-framework-openai` package** with dependencies on `agent-framework-core`, `openai`, and `packaging` only.
+2. **Class renames**: `OpenAIResponsesClient` → `OpenAIChatClient` (Responses API), `OpenAIChatClient` → `OpenAIChatCompletionClient` (Chat Completions API). Old names remain as deprecated aliases.
+3. **Deprecated classes**: `OpenAIAssistantsClient`, all `AzureOpenAI*Client` classes, `AzureAIClient`, `AzureAIAgentClient`, and `AzureAIProjectAgentProvider` are marked deprecated.
+4. **New `FoundryChatClient`** in azure-ai for Azure AI Foundry Responses API access, built on `RawFoundryChatClient(RawOpenAIChatClient)`.
+5. **All deprecated `AzureOpenAI*` classes** consolidated into a single file (`_deprecated_azure_openai.py`) in the azure-ai package for clean future deletion.
+6. **Core's `agent_framework.openai` and `agent_framework.azure` namespaces** become lazy-loading gateways, preserving backward-compatible import paths while removing hard dependencies.
+7. **Unified `model` parameter** replaces `model_id` (OpenAI), `deployment_name` (Azure OpenAI), and `model_deployment_name` (Azure AI) across all client constructors. The term `model` is intentionally generic: it naturally maps to an OpenAI model name *and* to an Azure OpenAI deployment name, making it straightforward to use `OpenAIChatClient` with either OpenAI or Azure OpenAI backends (via `AsyncAzureOpenAI`). Environment variables are similarly unified (e.g., `OPENAI_MODEL` instead of separate `OPENAI_CHAT_MODEL_ID` / `OPENAI_CHAT_COMPLETION_MODEL_ID`).
+8. **`FoundryAgent`** replaces the pattern of `Agent(client=AzureAIClient(...))` for connecting to pre-configured agents in Azure AI Foundry (PromptAgents and HostedAgents). The underlying `RawFoundryAgentChatClient` is an implementation detail — most users interact only with `FoundryAgent`. `AzureAIAgentClient` is separately deprecated as it refers to the V1 Agents Service API. See below for design rationale.
+
+### Foundry Agent Design: `FoundryAgentClient` vs `FoundryAgent`
+
+The existing `AzureAIClient` combines two concerns: CRUD lifecycle management (creating/deleting agents on the service) and runtime communication (sending messages via the Responses API). The new design removes CRUD entirely — users connect to agents that already exist in Foundry.
+
+**Two approaches were considered:**
+
+**Option A — `FoundryAgentClient` only (public ChatClient):**
+Users compose `Agent(client=FoundryAgentClient(...), tools=[...])`. This follows the universal `Agent(client=X)` pattern used by every other provider. However, a "client" that wraps a named remote agent (with `agent_name` as a constructor param) is semantically odd — clients typically wrap a model endpoint, not a specific agent.
+
+**Option B — `FoundryAgent` (Agent subclass) + private `_FoundryAgentChatClient` and public `RawFoundryAgentChatClient`:**
+Users write `FoundryAgent(agent_name="my-agent", ...)` for the common case. Internally, `FoundryAgent` creates a `_FoundryAgentChatClient` and passes it to the standard `Agent` base class. For advanced customization, users pass `client_type=RawFoundryAgentChatClient` (or a custom subclass) to control the client middleware layers. The `Agent(client=RawFoundryAgentChatClient(...))` composition pattern still works for users who prefer it.
+
+**Chosen option: Option B**, because:
+- The common case (`FoundryAgent(...)`) is a single object with no boilerplate.
+- `client_type=` gives full control over client middleware without parameter duplication — the agent forwards connection params to the client internally.
+- `RawFoundryAgent(RawAgent)` and `FoundryAgent(Agent)` mirror the established `RawAgent`/`Agent` pattern.
+- Runtime validation (only `FunctionTool` allowed) lives in `RawFoundryAgentChatClient._prepare_options`, ensuring it applies regardless of how the client is used — through `FoundryAgent`, `Agent(client=...)`, or any custom composition.
+
+**Public classes:**
+- `RawFoundryAgentChatClient(RawOpenAIChatClient)` — Responses API client that injects agent reference and validates tools. Extension point for custom client middleware.
+- `RawFoundryAgent(RawAgent)` — Agent without agent-level middleware/telemetry.
+- `FoundryAgent(AgentTelemetryLayer, AgentMiddlewareLayer, RawFoundryAgent)` — Recommended production agent.
+
+**Internal (private):**
+- `_FoundryAgentChatClient` — Full client with function invocation, chat middleware, and telemetry layers. Created automatically by `FoundryAgent`; users customize via `client_type=RawFoundryAgentChatClient` or a custom subclass.
+
+**Deprecated:**
+- `AzureAIClient` — replaced by `FoundryAgent` (which uses `FoundryAgentClient` internally).
+- `AzureAIAgentClient` — refers to V1 Agents Service API, no direct replacement.
+- `AzureAIProjectAgentProvider` — replaced by `FoundryAgent`.

+# Chat History Persistence Consistency
+
+## Context and Problem Statement
+
+When using `ChatClientAgent` with tools, the `FunctionInvokingChatClient` (FIC) loops multiple times — service call → tool execution → service call → … — before producing a final response. There are two points of discrepancy between how chat history is stored by the framework's `ChatHistoryProvider` and how the underlying AI service stores chat history (e.g., OpenAI Responses with `store=true`):
+
+1. **Persistence timing**: The AI service persists messages after *each* service call within the FIC loop. The `ChatHistoryProvider` currently persists messages only once, at the *end* of the full agent run (after all FIC loop iterations complete).
+
+2. **Trailing `FunctionResultContent` storage**: When tool calling is terminated mid-loop (e.g., via `FunctionInvokingChatClient` termination filters), the final response from the agent may contain `FunctionResultContent` that was never sent to a subsequent service call. The AI service never stores this trailing `FunctionResultContent`, but the `ChatHistoryProvider` currently stores all response content, including the trailing `FunctionResultContent`.
+
+These discrepancies mean that a `ChatHistoryProvider`-managed conversation and a service-managed conversation can diverge in content and structure, even when processing the same interactions.
+
+### Practical Impact: Resuming After Tool-Call Termination
+
+Today, users of `AIAgent` get different behaviors depending on whether chat history is stored service-side or in a `ChatHistoryProvider`. This creates concrete challenges — for example, when the function call loop is terminated and the user wants to resume the conversation in a subsequent run. With service-stored history, the trailing `FunctionResultContent` is never persisted, so the last stored message is the `FunctionCallContent` from the service. With `ChatHistoryProvider`-stored history, the trailing `FunctionResultContent` *is* persisted. The user cannot know whether the last `FunctionResultContent` is in the chat history or not without inspecting the storage mechanism, making it difficult to write resumption logic that works correctly regardless of the storage backend.
+
+### Relationship Between the Two Discrepancies
+
+The persistence timing and `FunctionResultContent` trimming behaviors are interrelated:
+
+- **Per-service-call persistence**: When messages are persisted after each individual service call, trailing `FunctionResultContent` trimming is unnecessary. If tool calling is terminated, the `FunctionResultContent` from the terminated call was never sent to a subsequent service call, so it is never persisted. The per-service-call approach naturally matches the service's behavior.
+
+- **Per-run persistence**: When messages are batched and persisted at the end of the full run, trailing `FunctionResultContent` trimming becomes necessary to match the service's behavior. Without trimming, the stored history contains `FunctionResultContent` that the service would never have stored.
+
+## Decision Drivers
+
+- **A. Consistency**: The default behavior of `ChatHistoryProvider` should produce stored history that closely matches what the underlying AI service would store, minimizing surprise when switching between framework-managed and service-managed chat history.
+- **B. Atomicity**: A run that fails mid-way through a multi-step tool-calling loop should not leave chat history in a partially-updated state, unless the user explicitly opts into that behavior.
+- **C. Recoverability**: For long-running tool-calling loops, it should be possible to recover intermediate progress if the process is interrupted, rather than losing all work from the current run.
+- **D. Simplicity**: The default behavior should be easy to understand and predict for most users, without requiring knowledge of the FIC loop internals.
+- **E. Flexibility**: Regardless of the chosen default, users should be able to opt into the alternative behavior.
+
+## Considered Options
+
+- Option 1: Per-run persistence with opt-in FRC (FunctionResultContent) trimming
+- Option 2: Opt-in per-service-call persistence (via `RequirePerServiceCallChatHistoryPersistence`)
+
+## Pros and Cons of the Options
+
+### Option 1: Per-run persistence with opt-in FRC trimming
+
+Keep the current default behavior of persisting chat history only at the end of the full agent run. Add `FunctionResultContent` trimming as an opt-in behavior to improve consistency with service storage.
+
+- Good, because runs are atomic — chat history is only updated when the full run succeeds, satisfying driver B.
+- Good, because the mental model is simple: one run = one history update, satisfying driver D.
+- Good, because trimming trailing `FunctionResultContent` improves consistency with service storage, partially satisfying driver A.
+- Bad, because the default persistence timing still differs from the service's behavior (per-run vs. per-service-call), only partially satisfying driver A.
+- Bad, because if the process crashes mid-loop, all intermediate progress from the current run is lost, not satisfying driver C.
+- Bad, because this option alone does not provide a way for users to opt into per-service-call persistence, not satisfying driver E.
+
+### Option 2: Opt-in per-service-call persistence (via `RequirePerServiceCallChatHistoryPersistence`)
+
+Introduce an optional RequirePerServiceCallChatHistoryPersistence setting to persist chat history after each individual service call within the FIC loop, matching the AI service's behavior. Trailing `FunctionResultContent` trimming is unnecessary with this approach (it is naturally handled).
+
+Settings:
+- `RequirePerServiceCallChatHistoryPersistence` = `true`
+
+- Good, because the stored history matches the service's behavior when opting in for both timing and content, fully satisfying driver A.
+- Good, because intermediate progress is preserved if the process is interrupted, satisfying driver C.
+- Good, because no separate `FunctionResultContent` trimming logic is needed, reducing complexity.
+- Bad, because chat history may be left in an incomplete state if the run fails mid-loop (e.g., `FunctionCallContent` stored without corresponding `FunctionResultContent`), not satisfying driver B. A subsequent run cannot proceed without manually providing the missing `FunctionResultContent`.
+- Bad, because the mental model is more complex: a single run may produce multiple history updates, partially failing driver D.
+- Neutral, because users can opt out to per-run persistence if they prefer atomicity, satisfying driver E.
+
+## Decision Outcome
+
+Chosen option: **Option 2: Opt-in per-service-call persistence (via `RequirePerServiceCallChatHistoryPersistence`)**. The existing per-run persistence behavior is retained as-is, requiring no changes from users. Per-service-call persistence is available as an opt-in feature via the `RequirePerServiceCallChatHistoryPersistence` setting. This satisfies drivers B (atomicity) and D (simplicity) for the common case, while fully satisfying driver A (consistency) for users who opt into simulated service-stored behavior. Users who need per-service-call persistence for recoverability (driver C) can enable it explicitly.
+
+### Configuration Matrix
+
+The behavior depends on the combination of `UseProvidedChatClientAsIs` and `RequirePerServiceCallChatHistoryPersistence`:
+
+| `UseProvidedChatClientAsIs` | `RequirePerServiceCallChatHistoryPersistence` | Behavior |
+|---|---|---|
+| `false` (default) | `false` (default) | **Per-run persistence.** Messages are persisted at the end of the full agent run via the `ChatHistoryProvider`. |
+| `false` | `true` | **Per-service-call persistence (simulated).** A `PerServiceCallChatHistoryPersistingChatClient` middleware is automatically injected into the chat client pipeline between `FunctionInvokingChatClient` and the leaf `IChatClient`. Messages are persisted after each service call. A sentinel `ConversationId` causes FIC to treat the conversation as service-managed. |
+| `true` | `false` | **Per-run persistence.** No middleware is injected because the user has provided a custom chat client stack. Messages are persisted at the end of the run. |
+| `true` | `true` | **User responsibility.** The system checks whether the custom chat client stack includes a `PerServiceCallChatHistoryPersistingChatClient`. If not, a warning is emitted — the user is expected to have added their own per-service-call persistence mechanism. End-of-run persistence is skipped. |
+
+### Consequences
+
+- Good, because per-run persistence is atomic by default — chat history is only updated when the full run succeeds, satisfying driver B.
+- Good, because the default mental model is simple: one run = one history update, satisfying driver D.
+- Good, because users who opt into `RequirePerServiceCallChatHistoryPersistence` get stored history that matches the service's behavior for both timing and content, fully satisfying driver A.
+- Good, because per-service-call persistence preserves intermediate progress if the process is interrupted, satisfying driver C when opted in.
+- Good, because no separate `FunctionResultContent` trimming logic is needed when per-service-call persistence is active — it is naturally handled.
+- Good, because conflict detection (configurable via `ThrowOnChatHistoryProviderConflict`, `WarnOnChatHistoryProviderConflict`, `ClearOnChatHistoryProviderConflict`) prevents misconfiguration when a service returns a `ConversationId` alongside a configured `ChatHistoryProvider`.
+- Bad, because per-service-call persistence (when opted in) may leave chat history in an incomplete state if the run fails mid-loop (e.g., `FunctionCallContent` stored without corresponding `FunctionResultContent`), requiring manual recovery in rare cases.
+- Neutral, because users who want per-service-call consistency can opt in via `RequirePerServiceCallChatHistoryPersistence = true`, satisfying driver E.
+- Neutral, because increased write frequency from per-service-call persistence may impact performance for some storage backends; this can be mitigated with a caching decorator.
+
+### Implementation Notes
+
+#### Conversation ID Consistency
+
+When `RequirePerServiceCallChatHistoryPersistence` is enabled, the `PerServiceCallChatHistoryPersistingChatClient`
+decorator also updates `session.ConversationId` after each service call. This handles two scenarios:
+
+1. **Framework-managed chat history** — the decorator sets a sentinel `ConversationId` on the response
+   so that `FunctionInvokingChatClient` treats the conversation as service-managed (clearing accumulated
+   history between iterations and not injecting duplicate `FunctionCallContent` during approval processing).
+
+2. **Service-stored chat history** — when the service returns a real `ConversationId`, the decorator
+   updates `session.ConversationId` immediately after each service call, rather than deferring the update
+   to the end of the run. This ensures intermediate ConversationId changes are captured even if the
+   process is interrupted mid-loop.
+
+For some service-stored scenarios (e.g., the Conversations API with the Responses API), there is only
+one thread with one ID, so every service call returns the same ConversationId and this per-call update
+makes no practical difference. Enabling `RequirePerServiceCallChatHistoryPersistence` ensures consistent
+per-service-call behavior across all service types regardless of how they manage ConversationIds.

+# Agent Evaluation Architecture with Azure AI Foundry Integration
+
+## Context and Problem Statement
+
+Azure AI Foundry provides a rich evaluation service for AI agents — built-in evaluators for agent behavior (task adherence, intent resolution), tool usage (tool call accuracy, tool selection), quality (coherence, fluency, relevance), and safety (violence, self-harm, prohibited actions). Results are viewable in the Foundry portal with dashboards and comparison views.
+
+However, using Foundry Evals with an agent-framework agent today requires significant manual effort. Developers must:
+
+1. Transform agent-framework's `Message`/`Content` types into the OpenAI-style agent message schema that Foundry evaluators expect
+2. Map tool definitions from agent-framework's `FunctionTool` format to evaluator-compatible schemas
+3. Manually wire up the correct Foundry data source type (`azure_ai_traces`, `jsonl`, `azure_ai_target_completions`, etc.) depending on their scenario
+4. Handle App Insights trace ID queries, response ID collection, and eval polling
+
+Additionally, evaluation is a concern that extends beyond any single provider. Developers may want to use local evaluators (LLM-as-judge, regex, keyword matching), third-party evaluation libraries, or multiple providers in combination. The architecture must support this without creating a Foundry-specific lock-in at the API level.
+
+### Functional Requirements for Agent Evaluation
+
+- **Single agents and workflows.** Evaluate both individual agent responses and multi-agent workflow results, with per-agent breakdown to pinpoint underperformance.
+- **One-shot and multi-turn conversations.** Capture full conversation trajectories — including tool calls and results — not just final query/response pairs.
+- **Conversation factoring.** Support splitting conversations into query/response in multiple ways (last turn, full trajectory, per-turn) because different factorings measure different things.
+- **Multiple providers, mix and match.** Run Foundry LLM-as-judge evaluators alongside fast local checks and custom evaluators on the same data, without restructuring code.
+- **Third-party extensibility.** Any evaluation library can participate by implementing the `Evaluator` protocol (Python) or `IAgentEvaluator` interface (.NET). No predetermined list of supported libraries — the protocol is intentionally simple (`evaluate(items) → results`) so that wrappers for libraries like DeepEval, RAGAS, or Promptfoo are straightforward to write.
+- **Bring your own evaluator.** Creating a custom evaluator should be as simple as writing a function.
+- **Evaluate without re-running.** Evaluate existing responses from logs or previous runs without invoking the agent again.
+
+## Decision Drivers
+
+- **Zero-friction evaluation**: Developers should go from "I have an agent" to "I have eval results" with minimal code.
+- **Provider-agnostic API**: Core evaluation capabilities must not be tied to any specific provider. Provider configuration should be separate from the evaluation call.
+- **Lowest concept count**: Introduce the fewest possible new types, abstractions, and APIs for developers to learn.
+- **Leverage existing knowledge**: The framework already knows which agents exist, what tools they have, and what conversations occurred. Evals should use this automatically rather than requiring the developer to re-specify it.
+- **Foundry-native results**: When using Foundry, results should be viewable in the Foundry portal with dashboards and comparison views.
+- **Progressive disclosure**: Simple scenarios should be near-zero code. Advanced scenarios should build on the same primitives.
+- **Cross-language parity**: Design must be implementable in both Python and .NET.
+
+## Considered Options
+
+1. **Provider-specific functions** — Build Foundry-specific helper functions (`evaluate_agent()`, etc.) directly in the Azure package. All eval functions take Foundry connection parameters.
+2. **Evaluator protocol with shared orchestration** — Define a provider-agnostic `Evaluator` protocol in the base agent library (`agent_framework` in Python, `Microsoft.Agents.AI` in .NET). Orchestration functions live alongside it. Providers implement the protocol.
+3. **Full eval framework** — Build comprehensive eval infrastructure including custom evaluator definitions, scoring profiles, and reporting inside agent-framework.
+
+## Decision Outcome
+
+Proposed option: "Evaluator protocol with shared orchestration", because it delivers the low-friction developer experience, supports multiple providers without API changes, and keeps the concept count low.
+
+### Usage Examples
+
+#### Evaluate an agent
+
+The agent is invoked once per query by default. For statistically meaningful evaluation, provide multiple diverse queries. For measuring **consistency** (does the same query produce reliable results?), use `num_repetitions` to run each query N times independently:
+
+**Python:**
+
+```python
+evals = FoundryEvals(
+    project_client=client,
+    model_deployment="gpt-4o",
+    evaluators=[FoundryEvals.RELEVANCE, FoundryEvals.COHERENCE],
+)
+
+results = await evaluate_agent(
+    agent=my_agent,
+    queries=[
+        "What's the weather in Seattle?",
+        "Plan a weekend trip to Portland",
+        "What restaurants are near Pike Place?",
+    ],
+    evaluators=evals,
+)
+for r in results:
+    r.assert_passed()
+```
+
+**C#:**
+
+```csharp
+var evals = new FoundryEvals(chatConfiguration, FoundryEvals.Relevance, FoundryEvals.Coherence);
+
+AgentEvaluationResults results = await agent.EvaluateAsync(
+    new[] {
+        "What's the weather in Seattle?",
+        "Plan a weekend trip to Portland",
+        "What restaurants are near Pike Place?",
+    },
+    evals);
+
+results.AssertAllPassed();
+```
+
+`evaluate_agent` returns one `EvalResults` per evaluator. Each result contains per-item scores with the evaluated response for auditing:
+
+```
+# results[0] (FoundryEvals)
+EvalResults(status="completed", passed=3, failed=0, total=3)
+  items[0]: EvalItemResult(
+    query="What's the weather in Seattle?",
+    response="It's currently 72°F and sunny in Seattle.",
+    scores={"relevance": 5, "coherence": 5})
+  items[1]: EvalItemResult(
+    query="Plan a weekend trip to Portland",
+    response="Here's a 2-day Portland itinerary...",
+    scores={"relevance": 4, "coherence": 5})
+  items[2]: EvalItemResult(
+    query="What restaurants are near Pike Place?",
+    response="Top restaurants near Pike Place Market: ...",
+    scores={"relevance": 5, "coherence": 4})
+```
+
+#### Measure consistency with repetitions
+
+Run each query multiple times to detect non-deterministic behavior:
+
+**Python:**
+
+```python
+results = await evaluate_agent(
+    agent=my_agent,
+    queries=["What's the weather in Seattle?"],
+    evaluators=evals,
+    num_repetitions=3,  # each query runs 3 times independently
+)
+# results contain 3 items (1 query × 3 repetitions)
+```
+
+**C#:**
+
+```csharp
+AgentEvaluationResults results = await agent.EvaluateAsync(
+    new[] { "What's the weather in Seattle?" },
+    evals,
+    numRepetitions: 3);  // each query runs 3 times independently
+// results contain 3 items (1 query × 3 repetitions)
+```
+
+#### Evaluate a response you already have
+
+When you already have agent responses, pass them directly to skip re-running the agent. Each query is paired with its corresponding response:
+
+**Python:**
+
+```python
+queries = ["What's the weather?", "What's the capital of France?"]
+responses = [await agent.run([Message("user", [q])]) for q in queries]
+
+results = await evaluate_agent(
+    responses=responses,
+    evaluators=evals,
+)
+```
+
+**C#:**
+
+```csharp
+var queries = new[] { "What's the weather?" };
+var responses = new List<AgentResponse>();
+foreach (var q in queries)
+    responses.Add(await agent.RunAsync(new[] { new ChatMessage(ChatRole.User, q) }));
+
+AgentEvaluationResults results = await agent.EvaluateAsync(
+    responses: responses,
+    evals);
+```
+
+Each `AgentResponse` already contains the conversation (query + response), so the evaluator extracts query/response from the conversation. When you pass `responses` without `queries`, the conversation is the source of truth.
+
+#### Evaluate with conversation split strategies
+
+By default, evaluators see only the last turn (final user message → final assistant response). For multi-turn conversations, you can control how the conversation is factored for evaluation:
+
+**Python:**
+
+```python
+results = await evaluate_agent(
+    agent=agent,
+    queries=["Plan a 3-day trip to Paris"],
+    evaluators=evals,
+    conversation_split=ConversationSplit.FULL,      # evaluate entire trajectory
+)
+
+# Or per-turn: each user→assistant exchange scored independently
+results = await evaluate_agent(
+    agent=agent,
+    queries=["Plan a 3-day trip to Paris"],
+    evaluators=evals,
+    conversation_split=ConversationSplit.PER_TURN,
+)
+```
+
+**C#:**
+
+```csharp
+// Full conversation as context
+AgentEvaluationResults results = await agent.EvaluateAsync(
+    new[] { "Plan a 3-day trip to Paris" },
+    evals,
+    splitter: ConversationSplitters.Full);
+
+// Per-turn splitting
+var items = EvalItem.PerTurnItems(conversation);  // one EvalItem per user turn
+var results = await evals.EvaluateAsync(items);
+```
+
+With `PER_TURN`, a 3-turn conversation produces 3 scored items:
+
+```
+EvalResults(status="completed", passed=3, failed=0, total=3)
+  items[0]: query="Plan a 3-day trip to Paris"    scores={"relevance": 5}
+  items[1]: query="What about restaurants?"        scores={"relevance": 4}
+  items[2]: query="Make it budget-friendly"        scores={"relevance": 5}
+```
+
+#### Evaluate a multi-agent workflow
+
+**Python:**
+
+```python
+result = await workflow.run("Plan a trip to Paris")
+eval_results = await evaluate_workflow(
+    workflow=workflow,
+    workflow_result=result,
+    evaluators=evals,
+)
+
+for r in eval_results:
+    print(f"  overall: {r.passed}/{r.total}")
+    for name, sub in r.sub_results.items():
+        print(f"    {name}: {sub.passed}/{sub.total}")
+```
+
+**C#:**
+
+```csharp
+WorkflowRunResult result = await workflow.RunAsync("Plan a trip to Paris");
+
+IReadOnlyList<AgentEvaluationResults> evalResults = await result.EvaluateAsync(evals);
+
+foreach (var r in evalResults)
+{
+    Console.WriteLine($"  overall: {r.Passed}/{r.Total}");
+    foreach (var (name, sub) in r.SubResults)
+        Console.WriteLine($"    {name}: {sub.Passed}/{sub.Total}");
+}
+```
+
+Workflows return one result per evaluator, with sub-results per agent in the workflow:
+
+```
+EvalResults(status="completed", passed=2, failed=0, total=2)
+  sub_results:
+    "planner":  EvalResults(passed=1, total=1)
+    "researcher": EvalResults(passed=1, total=1)
+```
+
+#### Mix multiple providers
+
+**Python:**
+
+```python
+@evaluator
+def is_helpful(response: str) -> bool:
+    return len(response.split()) > 10
+
+foundry = FoundryEvals(
+    project_client=client,
+    model_deployment="gpt-4o",
+    evaluators=[FoundryEvals.RELEVANCE, FoundryEvals.COHERENCE],
+)
+
+results = await evaluate_agent(
+    agent=agent,
+    queries=queries,
+    evaluators=[is_helpful, keyword_check("weather"), foundry],
+)
+```
+
+**C#:**
+
+```csharp
+IReadOnlyList<AgentEvaluationResults> results = await agent.EvaluateAsync(
+    queries,
+    evaluators: new IAgentEvaluator[]
+    {
+        new LocalEvaluator(
+            EvalChecks.KeywordCheck("weather"),
+            FunctionEvaluator.Create("is_helpful", (string r) => r.Split(' ').Length > 10)),
+        new FoundryEvals(chatConfiguration, FoundryEvals.Relevance, FoundryEvals.Coherence),
+    });
+```
+
+Multiple evaluators return one result each — `results[0]` is the local evaluator, `results[1]` is Foundry.
+
+#### Custom function evaluators
+
+**Python:**
+
+```python
+@evaluator
+def mentions_city(response: str, expected_output: str) -> bool:
+    return expected_output.lower() in response.lower()
+
+@evaluator
+def used_tools(conversation: list, tools: list) -> float:
+    # ... scoring logic
+    return score
+
+local = LocalEvaluator(mentions_city, used_tools)
+```
+
+`@evaluator` uses **parameter name injection** — the function's parameter names determine what data it receives from the `EvalItem`. Supported names: `query`, `response`, `expected`, `expected_tool_calls`, `conversation`, `tools`, `context`. Any combination is valid.
+
+**C#:**
+
+```csharp
+var local = new LocalEvaluator(
+    FunctionEvaluator.Create("mentions_city",
+        (EvalItem item) => item.ExpectedOutput != null
+            && item.Response.Contains(item.ExpectedOutput, StringComparison.OrdinalIgnoreCase)),
+    FunctionEvaluator.Create("is_concise",
+        (string response) => response.Split(' ').Length < 500));
+```
+
+## What To Build
+
+### Core: Evaluator Protocol
+
+A runtime-checkable protocol that any evaluation provider implements:
+
+```python
+@runtime_checkable
+class Evaluator(Protocol):
+    name: str
+
+    async def evaluate(
+        self, items: Sequence[EvalItem], *, eval_name: str = "Agent Framework Eval"
+    ) -> EvalResults: ...
+```
+
+The protocol is minimal — just `name` and `evaluate()`.
+
+### Core: EvalItem
+
+Provider-agnostic data format for items to evaluate:
+
+```python
+@dataclass
+class ExpectedToolCall:
+    name: str                                    # Tool/function name
+    arguments: dict[str, Any] | None = None      # None = don't check args
+
+@dataclass
+class EvalItem:
+    conversation: list[Message]               # Single source of truth
+    tools: list[FunctionTool] | None = None   # Agent's available tools
+    context: str | None = None
+    expected_output: str | None = None          # Ground-truth for comparison
+    expected_tool_calls: list[ExpectedToolCall] | None = None
+    split_strategy: ConversationSplitter | None = None
+
+    query: str       # property — derived from conversation split
+    response: str    # property — derived from conversation split
+```
+
+`conversation` is the single source of truth. `query` and `response` are derived properties — splitting the conversation at the last user message (default) and extracting text from each side. Changing the `split_strategy` consistently changes all derived values.
+
+`tools` provides typed `FunctionTool` objects — including MCP tools, which are automatically extracted after agent runs.
+
+### Internal: AgentEvalConverter
+
+Internal class that converts agent-framework types to `EvalItem`. Used by `evaluate_agent()` and `evaluate_workflow()` — not part of the public API:
+
+| Agent Framework | Eval Format |
+|---|---|
+| `Content.function_call` | `tool_call` in OpenAI chat format |
+| `Content.function_result` | `tool_result` in OpenAI chat format |
+| `FunctionTool` | `{name, description, parameters}` schema |
+| `Message` history | `conversation` list + `query`/`response` extraction |
+
+### Core: EvalResults
+
+Rich result type with convenience properties for CI integration:
+
+```python
+results.all_passed          # bool: no failures or errors (recursive for workflow)
+results.passed              # int: passing count
+results.failed              # int: failure count
+results.total               # int: total = passed + failed + errored
+results.items               # list[EvalItemResult]: per-item detail with query, response, and scores
+results.error               # str | None: error details on failure
+results.sub_results         # dict: per-agent breakdown (workflow evals)
+results.report_url          # str | None: portal link (Foundry)
+results.assert_passed()     # raises AssertionError with details
+```
+
+### Core: Orchestration Functions
+
+Provider-agnostic functions that extract data and delegate to evaluators:
+
+| Function | What it does |
+|---|---|
+| `evaluate_agent()` | Runs agent against test queries (or evaluates pre-existing `responses=`), converts to `EvalItem`s, passes to evaluator. Accepts optional `expected_output=` for ground-truth comparison, `expected_tool_calls=` for tool-correctness evaluation, and `num_repetitions=` for consistency measurement |
+| `evaluate_workflow()` | Extracts per-agent data from `WorkflowRunResult`, evaluates each agent and overall output. Per-agent breakdown in `sub_results`. Also accepts `num_repetitions=` |
+
+### Core: Conversation Split Strategies
+
+Multi-turn conversations must be split into query (input) and response (output) halves for evaluation. How you split determines *what you're evaluating*:
+
+**Last-turn split** — split at the last user message. Everything up to and including it is the query context; the agent's subsequent actions are the response:
+
+```
+conversation: user1 → assistant1 → user2 → assistant2(tool) → tool_result → assistant3
+query_messages:    [user1, assistant1, user2]
+response_messages: [assistant2(tool), tool_result, assistant3]
+```
+
+This evaluates: "Given all the context so far, did the agent answer the latest question well?" Best for response quality at a specific point in the conversation.
+
+**Full-conversation split** — the first user message is the query; everything after is the response:
+
+```
+query_messages:    [user1]
+response_messages: [assistant1, user2, assistant2(tool), tool_result, assistant3]
+```
+
+This evaluates: "Given the original request, did the entire conversation trajectory serve the user?" Best for task completion and overall conversation quality.
+
+**Per-turn split** — produces N eval items from an N-turn conversation. Each turn is evaluated with its cumulative context:
+
+```
+item 1: query = [user1],                        response = [assistant1]
+item 2: query = [user1, assistant1, user2],      response = [assistant2(tool), tool_result, assistant3]
+```
+
+This evaluates each response independently. Best for fine-grained analysis and pinpointing where a conversation goes wrong.
+
+These factorings produce different scores for the same conversation. The framework ships all three as built-in strategies, defaulting to last-turn. Developers can also provide a custom splitter — a function (Python) or `IConversationSplitter` implementation (.NET) — and override the strategy at the call site or per evaluator.
+
+### Azure AI: FoundryEvals
+
+`Evaluator` implementation backed by Azure AI Foundry:
+
+```python
+class FoundryEvals:
+    def __init__(self, *, project_client=None, openai_client=None,
+                 model_deployment: str, evaluators=None, ...)
+    async def evaluate(self, items, *, eval_name) -> EvalResults
+```
+
+**Smart auto-detection in `evaluate()`:**
+- Default evaluators: relevance, coherence, task_adherence
+- Auto-adds `tool_call_accuracy` when items have tools/`tool_definitions`
+- Filters out tool evaluators for items without tools
+
+### Azure AI: FoundryEvals Constants
+
+```python
+from agent_framework.foundry import FoundryEvals
+
+evaluators = [FoundryEvals.RELEVANCE, FoundryEvals.TOOL_CALL_ACCURACY]
+```
+
+Categories: Agent behavior, Tool usage, Quality, Safety.
+
+### Azure AI: Foundry-Specific Functions
+
+| Function | What it does |
+|---|---|
+| `evaluate_traces()` | Evaluate from stored response IDs or OTel traces |
+| `evaluate_foundry_target()` | Evaluate a Foundry-registered agent or deployment |
+
+### Core: LocalEvaluator and Function Evaluators
+
+`LocalEvaluator` implements the `Evaluator` protocol for fast, API-free evaluation. It runs check functions locally — useful for inner-loop development, CI smoke tests, and combining with cloud-based evaluators.
+
+Built-in checks:
+- `keyword_check(*keywords)` — response must contain specified keywords
+- `tool_called_check(*tool_names)` — agent must have called specified tools
+- `tool_calls_present` — all `expected_tool_calls` names appear in conversation (unordered, extras OK)
+- `tool_call_args_match` — expected tool calls match on name + arguments (subset match on args)
+
+Custom function evaluators use `@evaluator` to wrap plain Python functions. The function's **parameter names** determine what data it receives from the `EvalItem`:
+
+```python
+from agent_framework import evaluator, LocalEvaluator
+
+# Tier 1: Simple check — just query + response
+@evaluator
+def is_concise(response: str) -> bool:
+    return len(response.split()) < 500
+
+# Tier 2: Ground truth — compare against expected output
+@evaluator
+def mentions_city(response: str, expected_output: str) -> bool:
+    return expected_output.lower() in response.lower()
+
+# Tier 3: Full context — inspect conversation and tools
+@evaluator
+def used_tools(conversation: list, tools: list) -> float:
+    # ... scoring logic
+    return score
+
+local = LocalEvaluator(is_concise, mentions_city, used_tools)
+```
+
+Supported parameters: `query`, `response`, `expected`, `expected_tool_calls`, `conversation`, `tools`, `context`.
+Return types: `bool`, `float` (≥0.5 = pass), `dict` with `score` or `passed` key, or `CheckResult`.
+
+Async functions are handled automatically — `@evaluator` detects `async def` and produces the right wrapper.
+
+### Example: GAIA Benchmark
+
+[GAIA](https://huggingface.co/gaia-benchmark) tests real-world multi-step tasks with known expected answers. Each task has a question and a ground-truth answer, with optional file attachments. The framework accommodates GAIA's knobs (difficulty levels, file inputs, multi-step tool use) through the existing `EvalItem` fields:
+
+```python
+from datasets import load_dataset
+from agent_framework import evaluate_agent, evaluator, LocalEvaluator
+
+gaia = load_dataset("gaia-benchmark/GAIA", "2023_level1", split="test")
+
+@evaluator
+def exact_match(response: str, expected_output: str) -> bool:
+    return expected_output.strip().lower() in response.strip().lower()
+
+# Simple path — evaluate_agent handles running + expected_output stamping
+results = await evaluate_agent(
+    agent=agent,
+    queries=[task["Question"] for task in gaia],
+    expected_output=[task["Final answer"] for task in gaia],
+    evaluators=LocalEvaluator(exact_match),
+)
+```
+
+### Package Location
+
+- Core types and orchestration: `agent_framework._eval`, `agent_framework._local_eval` (Python), `Microsoft.Agents.AI` (.NET)
+- Foundry provider: `agent_framework_azure_ai._foundry_evals` (Python), `Microsoft.Agents.AI.AzureAI` (.NET)
+- Azure-AI re-exports core types for convenience (Python)
+
+## Known Limitations
+
+1. **Tool evaluators require query + agent**: Tool evaluators need tool definition schemas. When using these evaluators with `evaluate_agent(responses=...)`, provide `queries=` and pass an agent with tool definitions.
+2. **`model_deployment` always required**: Could potentially be inferred from the Foundry project configuration.
+
+## Open Questions
+
+1. **Red teaming non-registered agents**: Requires Foundry API support for callback-based flows.
+2. **Datasets with expected outputs**: A dataset abstraction for pre-populating `expected_output` values across eval runs is a natural next step but not yet designed.
+3. **Multi-modal evaluation**: The `conversation` field on `EvalItem` already stores full `Message`/`Content` (Python) and `ChatMessage` (.NET) objects, which can represent multi-modal content (images, audio, structured data). Evaluators that accept the full `EvalItem` or `conversation` parameter can access this content today. However, the convenience shortcuts — `query`/`response` string projections and the `FunctionEvaluator` string overloads — are text-only. Multi-modal-aware evaluators should use the full-item path (`Func<EvalItem, CheckResult>` in .NET, `conversation: list` parameter in Python).
+
+## .NET Implementation Design
+
+### Key Difference: MEAI Ecosystem
+
+Unlike Python, the .NET ecosystem already has `Microsoft.Extensions.AI.Evaluation` (v10.3.0) providing:
+
+- `IEvaluator` — per-item evaluation of `(messages, chatResponse) → EvaluationResult`
+- `CompositeEvaluator` — combines multiple evaluators
+- Quality evaluators — `RelevanceEvaluator`, `CoherenceEvaluator`, `GroundednessEvaluator`
+- Safety evaluators — `ContentHarmEvaluator`, `ProtectedMaterialEvaluator`
+- Metric types — `NumericMetric`, `BooleanMetric`, `StringMetric`
+
+The .NET integration uses MEAI's `IEvaluator` directly — no new evaluator interface. Our contribution is the **orchestration layer**: extension methods that run agents, extract data, call `IEvaluator` per item, and aggregate results.
+
+### Architecture

+
+All evaluators implement MEAI's `IEvaluator`. The orchestration layer doesn't need to know which kind — it calls `EvaluateAsync(messages, chatResponse)` per item on all of them. `FoundryEvals` handles batching internally (buffers items, submits once, returns per-item results).
+
+### .NET Core Types
+
+**No new evaluator interface.** Use MEAI's `IEvaluator` directly.
+
+**`AgentEvaluationResults`** — The only new type. Aggregates per-item MEAI `EvaluationResult`s across a batch of queries:
+
+```csharp
+public class AgentEvaluationResults
+{
+    public string Provider { get; init; }
+    public string? ReportUrl { get; init; }
+
+    // Per-item — standard MEAI EvaluationResult, unchanged
+    public IReadOnlyList<EvaluationResult> Items { get; init; }
+
+    // Aggregate pass/fail derived from metric interpretations
+    public int Passed { get; }
+    public int Failed { get; }
+    public int Total { get; }
+    public bool AllPassed { get; }
+
+    // Workflow: per-agent breakdown
+    public IReadOnlyDictionary<string, AgentEvaluationResults>? SubResults { get; init; }
+
+    public void AssertAllPassed(string? message = null);
+}
+```
+
+### .NET Evaluator Implementations
+
+All implement MEAI's `IEvaluator`:
+
+**`LocalEvaluator`** — Runs lambda checks locally, returns `BooleanMetric` per check:
+
+```csharp
+var local = new LocalEvaluator(
+    FunctionEvaluator.Create("is_concise",
+        (string response) => response.Split().Length < 500),
+    EvalChecks.KeywordCheck("weather"),
+    EvalChecks.ToolCalledCheck("get_weather"));
+```
+
+**MEAI evaluators** — Used directly, no adapter needed:
+
+```csharp
+var quality = new CompositeEvaluator(
+    new RelevanceEvaluator(),
+    new CoherenceEvaluator());
+```
+
+**`FoundryEvals`** — Implements `IEvaluator` but batches internally. On first call, buffers the item. On the last item (or when explicitly flushed), submits the batch to Foundry and distributes per-item results:
+
+```csharp
+var foundry = new FoundryEvals(projectClient, "gpt-4o");
+```
+
+### .NET Orchestration: Extension Methods
+
+```csharp
+public static class AgentEvaluationExtensions
+{
+    // Evaluate an agent against test queries
+    public static Task<AgentEvaluationResults> EvaluateAsync(
+        this AIAgent agent,
+        IEnumerable<string> queries,
+        IEvaluator evaluator,
+        ChatConfiguration? chatConfiguration = null,
+        IEnumerable<string>? expectedOutput = null,
+        CancellationToken cancellationToken = default);
+
+    // Evaluate pre-existing responses (without re-running the agent)
+    public static Task<AgentEvaluationResults> EvaluateAsync(
+        this AIAgent agent,
+        AgentResponse responses,
+        IEvaluator evaluator,
+        IEnumerable<string>? queries = null,
+        ChatConfiguration? chatConfiguration = null,
+        IEnumerable<string>? expectedOutput = null,
+        CancellationToken cancellationToken = default);
+
+    // Evaluate with multiple evaluators (one result per evaluator)
+    public static Task<IReadOnlyList<AgentEvaluationResults>> EvaluateAsync(
+        this AIAgent agent,
+        IEnumerable<string> queries,
+        IEnumerable<IEvaluator> evaluators,
+        ChatConfiguration? chatConfiguration = null,
+        IEnumerable<string>? expectedOutput = null,
+        CancellationToken cancellationToken = default);
+
+    // Evaluate a workflow run with per-agent breakdown
+    public static Task<AgentEvaluationResults> EvaluateAsync(
+        this Run run,
+        IEvaluator evaluator,
+        ChatConfiguration? chatConfiguration = null,
+        bool includeOverall = true,
+        bool includePerAgent = true,
+        CancellationToken cancellationToken = default);
+}
+```
+
+**Usage:**
+
+```csharp
+// MEAI evaluators — just works
+var results = await agent.EvaluateAsync(
+    queries: ["What's the weather?"],
+    evaluator: new RelevanceEvaluator(),
+    chatConfiguration: new ChatConfiguration(evalClient));
+
+// Local checks
+var results = await agent.EvaluateAsync(
+    queries: ["What's the weather?"],
+    evaluator: new LocalEvaluator(
+        EvalChecks.KeywordCheck("weather")));
+
+// Foundry cloud
+var results = await agent.EvaluateAsync(
+    queries: ["What's the weather?"],
+    evaluator: new FoundryEvals(projectClient, "gpt-4o"));
+
+// Evaluate existing response (without re-running the agent)
+var response = await agent.RunAsync("What's the weather?");
+var results = await agent.EvaluateAsync(
+    responses: response,
+    queries: ["What's the weather?"],
+    evaluator: new FoundryEvals(projectClient, "gpt-4o"));
+
+// Mixed — one result per evaluator
+var results = await agent.EvaluateAsync(
+    queries: ["What's the weather?"],
+    evaluators: [
+        new LocalEvaluator(EvalChecks.KeywordCheck("weather")),
+        new RelevanceEvaluator(),
+        new FoundryEvals(projectClient, "gpt-4o")
+    ],
+    chatConfiguration: new ChatConfiguration(evalClient));
+
+// Workflow with per-agent breakdown
+Run run = await workflowRunner.RunAsync(workflow, "Plan a trip");
+var results = await run.EvaluateAsync(
+    evaluator: new FoundryEvals(projectClient, "gpt-4o"));
+```
+
+### .NET Function Evaluators
+
+Typed factory overloads (C# equivalent of Python's `@evaluator`):
+
+```csharp
+public static class FunctionEvaluator
+{
+    public static EvalCheck Create(string name, Func<string, bool> check);           // response only
+    public static EvalCheck Create(string name, Func<string, string?, bool> check);  // expectedOutput
+    public static EvalCheck Create(string name, Func<EvalItem, bool> check);         // full item
+    public static EvalCheck Create(string name, Func<EvalItem, CheckResult> check);  // full control
+    public static EvalCheck Create(string name, Func<string, Task<bool>> check);     // async
+}
+```
+
+`EvalItem` is a lightweight record used only by `FunctionEvaluator` and `LocalEvaluator` to pass context to check functions. It is not part of the `IEvaluator` interface:
+
+```csharp
+public record ExpectedToolCall(string Name, IReadOnlyDictionary<string, object>? Arguments = null);
+
+public sealed class EvalItem
+{
+    public EvalItem(string query, string response, IReadOnlyList<ChatMessage> conversation);
+
+    public string Query { get; }
+    public string Response { get; }
+    public IReadOnlyList<ChatMessage> Conversation { get; }
+    public IReadOnlyList<AITool>? Tools { get; set; }
+    public string? ExpectedOutput { get; set; }
+    public IReadOnlyList<ExpectedToolCall>? ExpectedToolCalls { get; set; }
+    public string? Context { get; set; }
+    public IConversationSplitter? Splitter { get; set; }
+}
+```
+
+### Workflow Data Extraction (.NET)
+
+`run.EvaluateAsync()` walks `Run.OutgoingEvents` via LINQ:
+
+1. Pair `ExecutorInvokedEvent` / `ExecutorCompletedEvent` by `ExecutorId`
+2. Extract `AgentResponseEvent` for per-agent `ChatResponse`
+3. Call `evaluator.EvaluateAsync()` per invocation
+4. Group by `ExecutorId` for per-agent `SubResults`
+5. Use final workflow output for overall eval

+description: How to use the verify-samples tool to run, verify, and manage sample definitions in the Agent Framework repository. Use this when adding, updating, or running sample verification.
+---
+
+# verify-samples Tool
+
+The `verify-samples` project (`dotnet/eng/verify-samples/`) is an automated tool that runs sample projects and verifies their output using deterministic checks and AI-powered verification.
+
+## Running verify-samples
+
+```bash
+cd dotnet
+
+# Run all samples across all categories
+dotnet run --project eng/verify-samples -- --log results.log --csv results.csv
+
+# Run a specific category
+dotnet run --project eng/verify-samples -- --category 02-agents --log results.log
+
+# Run specific samples by name
+dotnet run --project eng/verify-samples -- Agent_Step02_StructuredOutput Agent_Step09_AsFunctionTool
+
+# Control parallelism (default 8)
+dotnet run --project eng/verify-samples -- --parallel 8 --log results.log
+
+# Combine options
+dotnet run --project eng/verify-samples -- --category 03-workflows --parallel 4 --log results.log --csv results.csv
+```
+
+### Required Environment Variables
+
+The tool itself needs:
+- `AZURE_OPENAI_ENDPOINT` — for the AI verification agent
+- `AZURE_OPENAI_DEPLOYMENT_NAME` (optional, defaults to `gpt-5-mini`)
+
+Individual samples require their own env vars (e.g., `AZURE_AI_PROJECT_ENDPOINT`). The tool automatically checks and skips samples with missing env vars.
+
+### Output Files
+
+- `--log results.log` — detailed per-sample log with stdout/stderr, AI reasoning, and a summary
+- `--csv results.csv` — tabular summary with Sample, ProjectPath, Status, FailedChecks, and Failures columns
+
+## Sample Categories
+
+Definitions are in the `dotnet/eng/verify-samples/` directory:
+
+| Category | Config File | Registered Key |
+|----------|-------------|----------------|
+| 01-get-started | `GetStartedSamples.cs` | `01-get-started` |
+| 02-agents | `AgentsSamples.cs` | `02-agents` |
+| 03-workflows | `WorkflowSamples.cs` | `03-workflows` |
+
+Categories are registered in `VerifyOptions.cs` in the `s_sampleSets` dictionary.
+
+## SampleDefinition Properties
+
+Each sample is defined as a `SampleDefinition` in the appropriate config file. Key properties:
+
+```csharp
+new SampleDefinition
+{
+    // Required: Display name for the sample
+    Name = "Agent_Step02_StructuredOutput",
+
+    // Required: Relative path from dotnet/ to the sample project directory
+    ProjectPath = "samples/02-agents/Agents/Agent_Step02_StructuredOutput",
+
+    // Environment variables the sample requires (throws if missing)
+    RequiredEnvironmentVariables = ["AZURE_OPENAI_ENDPOINT"],
+
+    // Environment variables with defaults that would prompt on console if unset
+    OptionalEnvironmentVariables = ["AZURE_OPENAI_DEPLOYMENT_NAME"],
+
+    // Skip this sample with a reason (for structural issues only)
+    SkipReason = null, // or "Requires external service X."
+
+    // Deterministic checks: substrings that must appear in stdout
+    MustContain = ["=== Section Header ==="],
+
+    // Substrings that must NOT appear in stdout
+    MustNotContain = [],
+
+    // If true, only MustContain checks are used (no AI verification)
+    IsDeterministic = false,
+
+    // AI verification: natural-language descriptions of expected output
+    // Each entry describes one aspect to verify independently
+    ExpectedOutputDescription =
+    [
+        "The output should show structured person information with Name, Age, and Occupation fields.",
+        "The output should not contain error messages or stack traces.",
+    ],
+
+    // Stdin inputs to feed to the sample (for interactive samples)
+    Inputs = ["Y", "Y", "Y"],
+
+    // Delay between stdin inputs in ms (default 2000, increase for LLM calls between inputs)
+    InputDelayMs = 3000,
+}
+```
+
+## How to Add a New Sample Definition
+
+1. **Check the sample's Program.cs** to understand:
+   - What environment variables it reads (look for `GetEnvironmentVariable`)
+   - Whether it needs stdin input (look for `Console.ReadLine`, `Application.GetInput`)
+   - Whether it has an external loop (look for `EXIT` patterns in YAML workflows)
+   - What output it produces (section headers, markers, expected behavior)
+   - Whether it exits on its own or runs as a server
+
+2. **Choose the right verification strategy:**
+   - **Deterministic** (`IsDeterministic = true`): Use `MustContain` for samples with fixed output strings. No AI verification.
+   - **AI-verified** (default): Use `ExpectedOutputDescription` with semantic descriptions. Write expectations that are flexible enough for non-deterministic LLM output.
+   - **Both**: Use `MustContain` for fixed markers AND `ExpectedOutputDescription` for LLM-generated content.
+
+3. **Set `SkipReason` only for structural issues:**
+   - Web servers that don't exit
+   - Multi-process client/server architectures
+   - Samples requiring external infrastructure (MCP servers you can't reach, Docker, etc.)
+   - Do NOT skip for missing env vars — the tool checks those dynamically.
+
+4. **For interactive samples, provide `Inputs`:**
+   - Samples using `Application.GetInput(args)` need one initial input
+   - Samples with `Console.ReadLine()` approval loops need `"Y"` inputs
+   - YAML workflows with `externalLoop` need `"EXIT"` as the last input
+   - Set `InputDelayMs` to 3000-8000ms for samples with LLM calls between inputs
+
+5. **Add the definition** to the appropriate config file (e.g., `AgentsSamples.cs`) in the `All` list.
+
+6. **Register new categories** (if needed) in `VerifyOptions.cs` `s_sampleSets` dictionary.
+
+### Writing Good ExpectedOutputDescription
+
+- Write descriptions that are **semantically flexible** — LLM output varies between runs
+- Each array entry should describe **one independent aspect** to verify
+- Always include `"The output should not contain error messages or stack traces."` as the last entry
+- Avoid exact wording expectations — use "should mention", "should contain information about", "should show"
+- Bad: `"The output should say 'The weather in Amsterdam is cloudy with a high of 15°C'"`
+- Good: `"The output should contain weather information about Amsterdam mentioning cloudy weather with a high of 15°C."`
+
+### Example: Simple LLM Sample
+
+```csharp
+new SampleDefinition
+{
+    Name = "Agent_With_AzureOpenAIChatCompletion",
+    ProjectPath = "samples/02-agents/AgentProviders/Agent_With_AzureOpenAIChatCompletion",
+    RequiredEnvironmentVariables = ["AZURE_OPENAI_ENDPOINT"],
+    OptionalEnvironmentVariables = ["AZURE_OPENAI_DEPLOYMENT_NAME"],
+    ExpectedOutputDescription =
+    [
+        "The output should contain a joke about a pirate.",
+        "The output should not contain error messages or stack traces.",
+    ],
+},
+```
+
+### Example: Deterministic Sample
+
+```csharp
+new SampleDefinition
+{
+    Name = "Workflow_Declarative_GenerateCode",
+    ProjectPath = "samples/03-workflows/Declarative/GenerateCode",
+    IsDeterministic = true,
+    MustContain = ["WORKFLOW: Parsing", "WORKFLOW: Defined"],
+    ExpectedOutputDescription = ["The output should show a YAML workflow being parsed and C# code being generated from it."],
+},
+```
+
+### Example: Interactive Sample with Approval Loop
+
+```csharp
+new SampleDefinition
+{
+    Name = "FoundryAgent_Hosted_MCP",
+    ProjectPath = "samples/02-agents/ModelContextProtocol/FoundryAgent_Hosted_MCP",
+    RequiredEnvironmentVariables = ["AZURE_AI_PROJECT_ENDPOINT"],
+    OptionalEnvironmentVariables = ["AZURE_AI_MODEL_DEPLOYMENT_NAME"],
+    Inputs = ["Y", "Y", "Y", "Y", "Y"],
+    InputDelayMs = 5000,
+    ExpectedOutputDescription = ["The output should show an agent using the Microsoft Learn MCP tool with approval prompts."],
+},
+```
+
+### Example: Declarative Workflow with External Loop
+
+```csharp
+new SampleDefinition
+{
+    Name = "Workflow_Declarative_FunctionTools",
+    ProjectPath = "samples/03-workflows/Declarative/FunctionTools",
+    RequiredEnvironmentVariables = ["AZURE_AI_PROJECT_ENDPOINT"],
+    OptionalEnvironmentVariables = ["AZURE_AI_MODEL_DEPLOYMENT_NAME"],
+    Inputs = ["What are today's specials?", "EXIT"],
+    InputDelayMs = 8000,
+    ExpectedOutputDescription = ["The output should show a workflow calling function tools to answer a question about restaurant specials."],
+},
+```
+
+### Example: Skipped Sample
+
+```csharp
+new SampleDefinition
+{
+    Name = "Agent_MCP_Server",

 ## Key Conventions
 
-- **Encoding**: All new files must be saved with UTF-8 encoding with BOM (Byte Order Mark). This is required for `dotnet format` to work correctly.
+- **Command output capture**: When running `dotnet build`, `dotnet test`, `dotnet format`, or similar commands, redirect output to a temp file first (e.g., `dotnet build --tl:off 2>&1 | Out-File $env:TEMP\build.log`), then analyze the file as needed. This avoids re-running expensive commands when the initial analysis misses something.
+- **Encoding**: All new files must be saved with UTF-8 encoding with BOM (Byte Order Mark). This is required for `dotnet format` to work correctly. When using PowerShell `Set-Content`, always pass `-Encoding UTF8BOM` to preserve the BOM (e.g., `Set-Content $file $content -NoNewline -Encoding UTF8BOM`).
 - **Copyright header**: `// Copyright (c) Microsoft. All rights reserved.` at top of all `.cs` files
 - **XML docs**: Required for all public methods and classes
 - **Async**: Use `Async` suffix for methods returning `Task`/`ValueTask`

-# Agent Skills Sample
-
-This sample demonstrates how to use **Agent Skills** with a `ChatClientAgent` in the Microsoft Agent Framework.
-
-## What are Agent Skills?
-
-Agent Skills are modular packages of instructions and resources that enable AI agents to perform specialized tasks. They follow the [Agent Skills specification](https://agentskills.io/) and implement the progressive disclosure pattern:
-
-1. **Advertise**: Skills are advertised with name + description (~100 tokens per skill)
-2. **Load**: Full instructions are loaded on-demand via `load_skill` tool
-3. **Resources**: References and other files loaded via `read_skill_resource` tool
-
-## Skills Included
-
-### expense-report
-Policy-based expense filing with spending limits, receipt requirements, and approval workflows.
-- `references/POLICY_FAQ.md` — Detailed expense policy Q&A
-- `assets/expense-report-template.md` — Submission template
-
-## Project Structure

-```
-
-## Running the Sample
-
-### Prerequisites
-- .NET 10.0 SDK
-- Azure OpenAI endpoint with a deployed model
-
-### Setup
-1. Set environment variables:
-   ```bash
-   export AZURE_OPENAI_ENDPOINT="https://your-endpoint.openai.azure.com/"
-   export AZURE_OPENAI_DEPLOYMENT_NAME="gpt-4o-mini"
-   ```
-
-2. Run the sample:
-   ```bash
-   dotnet run
-   ```
-
-### Examples
-
-The sample runs two examples:
-
-1. **Expense policy FAQ** — Asks about tip reimbursement; the agent loads the expense-report skill and reads the FAQ resource
-2. **Filing an expense report** — Multi-turn conversation to draft an expense report using the template asset

-# Expense Policy — Frequently Asked Questions
-
-## Meals
-
-**Q: Can I expense coffee or snacks during the workday?**
-A: Daily coffee/snacks under $10 are not reimbursable (considered personal). Coffee purchased during a client meeting or team working session is reimbursable as a team meal.
-
-**Q: What if a team dinner exceeds the per-person limit?**
-A: The $75/person limit applies as a guideline. Overages up to 20% are accepted with a written justification (e.g., "client dinner at venue chosen by client"). Overages beyond 20% require pre-approval from your VP.
-
-**Q: Do I need to list every attendee?**
-A: Yes. For client meals, list the client's name and company. For team meals, list all employee names. For groups over 10, you may attach a separate attendee list.
-
-## Travel
-
-**Q: Can I book a premium economy or business class flight?**
-A: Economy class is the standard. Premium economy is allowed for flights over 6 hours. Business class requires VP pre-approval and is generally reserved for flights over 10 hours or medical accommodation.
-
-**Q: What about ride-sharing (Uber/Lyft) vs. rental cars?**
-A: Use ride-sharing for trips under 30 miles round-trip. Rent a car for multi-day travel or when ride-sharing would exceed $100/day. Always choose the compact/standard category unless traveling with 3+ people.
-
-**Q: Are tips reimbursable?**
-A: Tips up to 20% are reimbursable for meals, taxi/ride-share, and hotel housekeeping. Tips above 20% require justification.
-
-## Lodging
-
-**Q: What if the $250/night limit isn't enough for the city I'm visiting?**
-A: For high-cost cities (New York, San Francisco, London, Tokyo, Sydney), the limit is automatically increased to $350/night. No additional approval is needed. For other locations where rates are unusually high (e.g., during a major conference), request a per-trip exception from your manager before booking.
-
-**Q: Can I stay with friends/family instead and get a per-diem?**
-A: No. Contoso reimburses actual lodging costs only, not per-diems.
-
-## Subscriptions and Software
-
-**Q: Can I expense a personal productivity tool?**
-A: Software must be directly related to your job function. Tools like IDE licenses, design software, or project management apps are reimbursable. General productivity apps (note-taking, personal calendar) are not, unless your manager confirms a business need in writing.
-
-**Q: What about annual subscriptions?**
-A: Annual subscriptions over $200 require manager approval before purchase. Submit the approval email with your expense report.
-
-## Receipts and Documentation
-
-**Q: My receipt is faded/damaged. What do I do?**
-A: Try to obtain a duplicate from the vendor. If not possible, submit a Lost Receipt Affidavit (available from the Finance SharePoint site). You're limited to 2 affidavits per quarter.
-
-**Q: Do I need a receipt for parking meters or tolls?**
-A: For amounts under $15, no receipt is required — just note the date, location, and amount. For $15 and above, a receipt or bank/credit card statement excerpt is required.
-
-## Approval and Reimbursement
-
-**Q: My manager is on leave. Who approves my report?**
-A: Expense reports can be approved by your skip-level manager or any manager designated as an alternate approver in the expense system.
-
-**Q: Can I submit expenses from a previous quarter?**
-A: The standard 30-day window applies. Expenses older than 30 days require a written explanation and VP approval. Expenses older than 90 days are not reimbursable except in extraordinary circumstances (extended leave, medical emergency) with CFO approval.

+| Discovery | Automatic from directory path | Explicit via constructor |
+| Dynamic content | No (static files only) | Yes (factory delegates) |
+| Reusability | Copy skill directory | Inline or shared instances |
+
+For single-source scenarios, use the `AgentSkillsProvider` constructors directly. To combine multiple skill types, use the `AgentSkillsProviderBuilder`.
