-
-          cat > "${PR_BODY_FILE}" <<'EOF'
-          ### Motivation and Context
-
-          This automated update refreshes Python dev dependency pins across the workspace and reruns the repo validation gates before opening a pull request.
-
-          ### Description
-
-          - Ran `uv run poe upgrade-dev-dependencies`
-          - Refreshed dev dependency pins in workspace `pyproject.toml` files
-          - Refreshed `python/uv.lock` with `uv lock --upgrade`
-          - Reinstalled from the frozen lockfile and reran `check`, `typing`, and `test`
-
-          ### Contribution Checklist

-# 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 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_azure_ai 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.
-

-```
-
-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
-
-### .NET Package Structure
-
-| Package | Contents |
-|---------|----------|
-| `Microsoft.Agents.AI` | `IAgentEvaluator`, `AgentEvaluationResults`, `LocalEvaluator`, `FunctionEvaluator`, `EvalChecks`, `EvalItem`, `ExpectedToolCall`, `AgentEvaluationExtensions` |

-# 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)

-                                        └── 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_RESPONSES_MODEL_ID` / `OPENAI_CHAT_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.
-
-This means the trimming feature (introduced in [PR #4792](https://github.com/microsoft/agent-framework/pull/4792)) is primarily needed as a complement to per-run persistence. The `PersistChatHistoryAtEndOfRun` setting (introduced in [PR #4762](https://github.com/microsoft/agent-framework/pull/4762)) inverts the default so that per-service-call persistence is the standard behavior, and per-run persistence is opt-in.
-
-## 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: Default to per-run persistence with `FunctionResultContent` trimming (opt-in to per-service-call)
-- Option 2: Default to per-service-call persistence (opt-in to per-run)
-
-## Pros and Cons of the Options
-
-### Option 1: Default to per-run persistence with `FunctionResultContent` trimming
-
-Keep the current default behavior of persisting chat history only at the end of the full agent run. Add `FunctionResultContent` trimming as the default to improve consistency with service storage. Provide an opt-in setting for users who want per-service-call persistence.
-
-Settings:
-- `PersistChatHistoryAtEndOfRun` = `true`
-
-- 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.
-- Good, because users can opt in to per-service-call persistence for checkpointing/recovery scenarios, satisfying drivers C and E.
-- 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 by default.
-
-### Option 2: Default to per-service-call persistence
-
-Change the default 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). Provide an opt-in setting for users who want per-run atomicity with trimming.
-
-Settings:
-- `PersistChatHistoryAtEndOfRun` = `false` (default)
-
-- Good, because the stored history matches the service's behavior by default 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 — Default to per-service-call persistence**, because it fully satisfies the consistency driver (A), naturally handles `FunctionResultContent` trimming without additional logic, and provides better recoverability for long-running tool-calling loops. Per-run persistence remains available via the `PersistChatHistoryAtEndOfRun` setting for users who prefer atomic run semantics.
-
-### Configuration Matrix
-
-The behavior depends on the combination of `UseProvidedChatClientAsIs` and `PersistChatHistoryAtEndOfRun`:
-
-| `UseProvidedChatClientAsIs` | `PersistChatHistoryAtEndOfRun` | Behavior |
-|---|---|---|
-| `false` (default) | `false` (default) | **Per-service-call persistence.** A `ChatHistoryPersistingChatClient` middleware is automatically injected into the chat client pipeline between `FunctionInvokingChatClient` and the leaf `IChatClient`. Messages are persisted after each service call. |
-| `true` | `false` | **User responsibility.** No middleware is injected because the user has provided a custom chat client stack. The user is responsible for ensuring correct persistence behavior (e.g., by including their own persisting middleware). |
-| `false` | `true` | **Per-run persistence with marking.** A `ChatHistoryPersistingChatClient` middleware is injected, but configured to *mark* messages with metadata rather than store them immediately. At the end of the run, marked messages are stored. Trailing `FunctionResultContent` is trimmed. |
-| `true` | `true` | **Per-run persistence with warning.** The system checks whether the custom chat client stack includes a `ChatHistoryPersistingChatClient`. If not, a warning is emitted (particularly relevant for workflow handoff scenarios where trimming cannot be guaranteed). If no `ChatHistoryPersistingChatClient` is preset, all messages are stored at the end of the run, otherwise marked messages are stored. |
-
-### Consequences
-
-- Good, because the stored history matches the service's behavior by default for both timing and content, fully satisfying consistency (driver A).
-- Good, because intermediate progress is preserved if the process is interrupted, satisfying recoverability (driver C).
-- Good, because no separate `FunctionResultContent` trimming logic is needed in the default path, reducing complexity.
-- Good, because marking persisted messages with metadata enables deduplication and aids debugging.
-- Good, because warnings for custom chat client configurations without the persisting middleware help prevent silent failures in workflow handoff scenarios.
-- Bad, because chat history may be left in an incomplete state if the run fails mid-loop (e.g., `FunctionCallContent` stored without corresponding `FunctionResultContent`), requiring manual recovery in rare cases.
-- Bad, because the mental model is more complex for the default path: a single run may produce multiple history updates.
-- Neutral, because users who prefer atomic run semantics can opt in to per-run persistence via `PersistChatHistoryAtEndOfRun = true`.
-- 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
-
-The `ChatHistoryPersistingChatClient` middleware must also update the session's `ConversationId` consistently for both response-based and conversation-based service interactions, ensuring the session always reflects the latest service-provided identifier.

-- **Code coverage** uses `Microsoft.Testing.Extensions.CodeCoverage` with `--coverage --coverage-output-format cobertura`.
-- **Running a test project directly** is supported via `dotnet run --project <test-project>`. This bypasses the `dotnet test` infrastructure and runs the test executable directly with the MTP command line.
-
-- **Running tests across the solution** with a filter may cause some projects to match zero tests, which MTP treats as a failure (exit code 8). Use `--ignore-exit-code 8` to suppress this:
-
-```bash
-# Run all unit tests across the solution, ignoring projects with no matching tests
-dotnet test --solution ./agent-framework-dotnet.slnx --no-build -f net10.0 --ignore-exit-code 8
-```
-
-- **Running tests with `--solution` for a specific TFM** requires all projects in the solution to support that TFM. Not all projects target every framework (e.g., some are `net10.0`-only). Use `./dotnet/eng/scripts/New-FilteredSolution.ps1` to generate a filtered solution:
-
-```powershell
-# Generate a filtered solution for net472 and run tests
-$filtered = ./dotnet/eng/scripts/New-FilteredSolution.ps1 -Solution dotnet/agent-framework-dotnet.slnx -TargetFramework net472
-dotnet test --solution $filtered --no-build -f net472 --ignore-exit-code 8
-
-# Exclude samples and keep only unit test projects
-./dotnet/eng/scripts/New-FilteredSolution.ps1 -Solution dotnet/agent-framework-dotnet.slnx -TargetFramework net10.0 -ExcludeSamples -TestProjectNameFilter "*UnitTests*" -OutputPath dotnet/filtered-unit.slnx
-```
-
-```bash
-# Run tests via dotnet test (uses MTP under the hood)
-dotnet test --project ./tests/Microsoft.Agents.AI.UnitTests -f net10.0
-
-# Run tests with code coverage (Cobertura format)
-dotnet test --project ./tests/Microsoft.Agents.AI.UnitTests -f net10.0 --coverage --coverage-output-format cobertura --coverage-settings ./tests/coverage.runsettings
-
-# Run tests directly via dotnet run (MTP native command line)
-dotnet run --project ./tests/Microsoft.Agents.AI.UnitTests -f net10.0
-
-# Show MTP command line help
-dotnet run --project ./tests/Microsoft.Agents.AI.UnitTests -f net10.0 -- -?

-.SYNOPSIS
-    Generates a filtered .slnx solution file by removing projects that don't match the specified criteria.
-
-.DESCRIPTION
-    Parses a .slnx solution file and applies one or more filters:
-    - Removes projects that don't support the specified target framework (via MSBuild query).
-    - Optionally removes all sample projects (under samples/).
-    - Optionally filters test projects by name pattern (e.g., only *UnitTests*).
-    Writes the filtered solution to the specified output path and prints the path.
-
-.PARAMETER Solution
-    Path to the source .slnx solution file.
-
-.PARAMETER TargetFramework
-    The target framework to filter by (e.g., net10.0, net472).
-
-.PARAMETER Configuration
-    Optional MSBuild configuration used when querying TargetFrameworks. Defaults to Debug.
-
-.PARAMETER TestProjectNameFilter
-    Optional wildcard pattern to filter test project names (e.g., *UnitTests*, *IntegrationTests*).
-    When specified, only test projects whose filename matches this pattern are kept.
-
-.PARAMETER ExcludeSamples
-    When specified, removes all projects under the samples/ directory from the solution.
-
-.PARAMETER OutputPath
-    Optional output path for the filtered .slnx file. If not specified, a temp file is created.
-
-.EXAMPLE
-    # Generate a filtered solution and run tests
-    $filtered = ./dotnet/eng/scripts/New-FilteredSolution.ps1 -Solution dotnet/agent-framework-dotnet.slnx -TargetFramework net472
-    dotnet test --solution $filtered --no-build -f net472
-
-.EXAMPLE
-    # Generate a solution with only unit test projects
-    ./dotnet/eng/scripts/New-FilteredSolution.ps1 -Solution dotnet/agent-framework-dotnet.slnx -TargetFramework net10.0 -TestProjectNameFilter "*UnitTests*" -OutputPath filtered-unit.slnx
-
-.EXAMPLE
-    # Inline usage with dotnet test (PowerShell)
-    dotnet test --solution (./dotnet/eng/scripts/New-FilteredSolution.ps1 -Solution dotnet/agent-framework-dotnet.slnx -TargetFramework net472) --no-build -f net472

+# 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

+        └── assets/
+            └── expense-report-template.md
+```
+
+## 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.

-# Bounded Chat History with Vector Store Overflow
-
-This sample demonstrates how to create a custom `ChatHistoryProvider` that keeps a bounded window of recent messages in session state and automatically overflows older messages to a vector store. When the agent is invoked, it searches the vector store for relevant older messages and prepends them as memory context.
-
-## Concepts
-
-- **`TruncatingChatReducer`**: A custom `IChatReducer` that keeps the most recent N messages and exposes removed messages via a `RemovedMessages` property.
-- **`BoundedChatHistoryProvider`**: A custom `ChatHistoryProvider` that composes:
-  - `InMemoryChatHistoryProvider` for fast session-state storage (bounded by the reducer)
-  - `ChatHistoryMemoryProvider` for vector-store overflow and semantic search of older messages
-
-## Prerequisites
-
-- [.NET 10 SDK](https://dotnet.microsoft.com/download/dotnet/10.0)
-- An Azure OpenAI resource with:
-  - A chat deployment (e.g., `gpt-4o-mini`)
-  - An embedding deployment (e.g., `text-embedding-3-large`)
-
-## Configuration
-
-Set the following environment variables:
-
-| Variable | Description | Default |
-|---|---|---|
-| `AZURE_OPENAI_ENDPOINT` | Your Azure OpenAI endpoint URL | *(required)* |
-| `AZURE_OPENAI_DEPLOYMENT_NAME` | Chat model deployment name | `gpt-4o-mini` |
-| `AZURE_OPENAI_EMBEDDING_DEPLOYMENT_NAME` | Embedding model deployment name | `text-embedding-3-large` |
-
-## Running the Sample
-
-```bash
-dotnet run
-```
-
-## How it Works
-
-1. The agent starts a conversation with a bounded session window of 4 non-system, non-function messages (i.e., user/assistant turns). System messages are always preserved, and function call/result messages are truncated and not preserved.
-2. As messages accumulate beyond the limit, the `TruncatingChatReducer` removes the oldest messages.
-3. The `BoundedChatHistoryProvider` detects the removed messages and stores them in a vector store via `ChatHistoryMemoryProvider`.
-4. On subsequent invocations, the provider searches the vector store for relevant older messages and prepends them as memory context, allowing the agent to recall information from earlier in the conversation.
