-AI Support team will support Microsoft Agent Framework issues for customers under a **Unified support agreement when the issue arises from usage of Azure AI services** (Foundry Models, Foundry Agents etc.) in conjunction with the SDK. Conversely, if customer has any other / non unified support agreement and/or Agent Framework SDK is used in a way **not involving an Azure service**, it is treated as a purely open-source tool – Microsoft’s support organization will not handle it, and users should use GitHub or forums for assistance
-
-For Copilot Studio SDK implementation issues, customers should use GitHub Issues for assistance, as outlined above. Conversely, for prerequisites managed within the Copilot Studio portal, customers can rely on the standard Microsoft Copilot Studio support channels.

+# Hosted session identity context for Foundry Hosting
+
+## Context and Problem Statement
+
+Server-hosted Foundry agents need a way to scope per-user state (most notably `FoundryMemoryProvider` memories) by the end user that initiated the request. The Foundry platform already injects `x-agent-user-isolation-key` and `x-agent-chat-isolation-key` headers on every Responses request, but the agent-framework hosting layer did not surface those values to `AIContextProvider` instances. The provider's `stateInitializer` only received an `AgentSession?` with no identity attached, so per-user scoping was impossible without out-of-band plumbing.
+
+## Decision Drivers
+
+- Memory and any future user-private context must be partitioned per end user without per-sample boilerplate.
+- The identity must be **read-only** from the perspective of `AIContextProvider`s, so a buggy or hostile provider cannot escalate or leak across users.
+- The persisted session must validate against the live request on every resume to defend against session-id leak and in-process tampering.
+- The change must work for every existing hosted-agent type (`ChatClientAgent`, `FoundryAgent`, future ones) without per-type refactoring of cast-heavy code paths in `Microsoft.Agents.AI`.
+- Local Docker debugging must remain possible when the platform headers are absent.
+
+## Considered Options
+
+1. **`HostedSessionContext` stored in `AgentSessionStateBag`, exposed via a public read accessor and an `internal` setter.** Hosting writes once on session creation and validates on every resume.
+2. **Specialised `HostedAgentSession : AgentSession` wrapper** that carries `UserId`/`ChatId` properties, with `GetService<ChatClientAgentSession>()` as the unwrap escape hatch.
+3. **New property on `AgentSession` base class** (`HostedSessionContext? HostedContext { get; internal set; }`).
+4. **AsyncLocal middleware** that reads the headers and stuffs them into a per-request `AsyncLocal<HostedSessionContext>` consumed by the provider.
+
+For the source of identity:
+- A. The platform-injected `IsolationContext` exposed by `ResponseContext.Isolation` (typed `UserIsolationKey`/`ChatIsolationKey`).
+- B. The OpenAI Responses spec's top-level `request.User` field.
+- C. A custom HTTP header `x-client-user`.
+
+## Decision Outcome
+
+**Option 1** was chosen for the storage shape, sourced from **Option A** (`ResponseContext.Isolation`).
+
+Rationale:
+
+- **Wrapper rejected (Option 2).** `ChatClientAgentSession` is `sealed` and `ChatClientAgent` rejects any other session type via direct `is not ChatClientAgentSession` checks at multiple call sites. Wrapping would force non-trivial refactors across `Microsoft.Agents.AI` and a corresponding repeat for every other agent type.
+- **Base-class property rejected (Option 3).** Leaks "hosted" semantics into the universal `AgentSession` abstraction used by Durable, A2A, and CopilotStudio agents that have no notion of a hosted user.
+- **AsyncLocal rejected (Option 4).** Surfaces the concept only locally, requires every consumer to re-implement the bridge, and cannot be enforced as read-only.
+- **`request.User` rejected (Option B).** Set by the caller, not the platform. Forging it client-side trivially defeats per-user partitioning.
+- **`x-client-user` rejected (Option C).** Non-standard, requires custom HTTP plumbing, and duplicates the platform-provided isolation contract.
+
+Implementation summary in `Microsoft.Agents.AI.Foundry.Hosting`:
+
+| Type | Visibility | Purpose |
+|---|---|---|
+| `HostedSessionContext` | public sealed | Captures `UserId` and `ChatId` (both required, non-whitespace). |
+| `HostedSessionContextExtensions.GetHostedContext` | public | Read accessor for `AIContextProvider`s. |
+| `HostedSessionContextExtensions.SetHostedContext` | internal | Writer reserved for the hosting assembly. Backed by `AgentSessionStateBag` under a well-known key for serialisation. |
+| `HostedSessionIsolationKeyProvider` (abstract) | public | DI-resolvable factory. Async signature: `ValueTask<HostedSessionContext?> GetKeysAsync(ResponseContext, CreateResponse, CancellationToken)`. |
+| `PlatformHostedSessionIsolationKeyProvider` | internal sealed | Default implementation. Maps `context.Isolation.UserIsolationKey` and `context.Isolation.ChatIsolationKey`. Returns `null` when either is absent. |
+
+Behaviour added to `AgentFrameworkResponseHandler.CreateAsync`:
+
+1. Resolve `HostedSessionIsolationKeyProvider` from DI; fall back to `PlatformHostedSessionIsolationKeyProvider`.
+2. Call `GetKeysAsync(context, request, cancellationToken)`. A `null` result throws `InvalidOperationException` (becomes 500). A null/whitespace `UserId` or `ChatId` is rejected by `HostedSessionContext`'s constructor.
+3. Branch on the **session's existing context**, not on whether a `conversation_id` was supplied:
+   - **No session (`session is null`):** nothing to stamp; skip.
+   - **Session present but un-stamped (`GetHostedContext() is null`):** treat as fresh. This covers both newly-created sessions and pre-existing sessions whose `conversation_id` was provisioned externally (e.g. via `conversations.CreateProjectConversationAsync()`) before the first hosted-agent request. Stamp the resolved identity now.
+   - **Session present with stamped context:** strict resume. The persisted `UserId` and `ChatId` must equal the resolved values exactly. Mismatch throws `ResponsesApiException` with status 403 and body `Hosted session identity context mismatch`.
+
+## Consequences
+
+Positive:
+
+- Per-user memory partitioning works out of the box for any agent that consumes a `Microsoft.Agents.AI.Foundry.FoundryMemoryProvider` configured to read `session.GetHostedContext().UserId`.
+- Cross-user session-id leak and in-process tampering of the persisted identity both surface as a 403 with a deliberately uninformative body.
+- The identity is opaque to the framework, matching the platform's semantics. The framework never inspects user identity; the `IsolationContext` keys are pre-partitioned per agent.
+
+Negative:
+
+- Every existing hosted sample fails locally without a `HostedSessionIsolationKeyProvider` registered, because the platform headers are absent outside the platform. Mitigated by shipping `Hosted_Shared_Contributor_Setup` with `DevTemporaryLocalSessionIsolationKeyProvider` and `AddDevTemporaryLocalContributorSetup`, and migrating all 9 existing responses samples.
+- An attacker who can plant an un-stamped session under a victim's `conversation_id` *before* the victim's first hosted-agent request would be stamped with the attacker's identity on that first request. This is not a regression vs. behaviour without this contract, and is mitigated in practice because the `conversation_id` namespace is allocated by the platform per project. Once a session is stamped, the strict equality check fully defends the resume path.
+
+## Out of scope
+
+- Per-request `User` field on `CreateResponse` is intentionally not consumed; only the platform `IsolationContext` headers carry trustworthy identity.
+- Generic (non-Foundry) hosting layers can re-define an equivalent type if needed; nothing in this ADR is moved into `Microsoft.Agents.AI.Hosting` because `Microsoft.Agents.AI.Foundry.Hosting` does not depend on it.
+- HMAC tamper signatures over the persisted context are not implemented; comparison against `ResponseContext.Isolation` on every request is sufficient because the platform sets those headers at the trust boundary.

+# MCP-Based Agent Skills Sample
+
+This sample demonstrates how to discover **Agent Skills served over MCP** with a `ChatClientAgent`.
+
+## What it demonstrates
+
+- Hosting a small MCP server (in this same executable, launched with `--server`) that
+  exposes skill resources following the SEP-2640 convention.
+- Connecting an `McpClient` to the embedded server via stdio transport.
+- Building an `AgentSkillsProvider` via `UseMcpSkills(client)`, which reads
+  `skill://index.json` (SEP-2640 canonical discovery) and constructs skills from the
+  index entries.
+- The progressive disclosure pattern across MCP: advertise → load → read resources, exactly
+  as for filesystem-backed skills.
+
+## Running the Sample
+
+### Prerequisites
+
+- .NET 10.0 SDK
+- Azure OpenAI endpoint with a deployed model
+
+### Setup
+
+```powershell
+$env:AZURE_OPENAI_ENDPOINT="https://your-endpoint.openai.azure.com/"
+$env:AZURE_OPENAI_DEPLOYMENT_NAME="gpt-5.4-mini"
+```
+
+### Run

+# Foundry Toolbox MCP Skills
+
+This sample uses
+`AgentSkillsProviderBuilder` to discover MCP-based skills from a Foundry Toolbox endpoint
+and inject them as `AIContextProviders` so the agent can discover and use them at runtime.
+
+## What this sample demonstrates
+
+- Connecting to a Foundry toolbox's MCP endpoint via Streamable HTTP transport
+- Injecting a fresh Azure AI bearer token (`https://ai.azure.com/.default`) on every MCP request
+- Using `AgentSkillsProviderBuilder.UseMcpSkills(client)` to discover skills from the toolbox
+- Injecting the discovered skills into `AIProjectClient.AsAIAgent(...)` via `AIContextProviders`
+
+## Prerequisites
+
+- A Microsoft Foundry project with a toolbox already configured
+- The toolbox MCP endpoint must expose `skill://index.json` with `skill-md` entries (SEP-2640). If the resource is absent, the sample runs but the skills provider will be empty.
+- Azure CLI installed and authenticated (`az login`)
+
+Set the following environment variables:
+
+```powershell
+$env:AZURE_AI_PROJECT_ENDPOINT="https://your-foundry-service.services.ai.azure.com/api/projects/your-foundry-project"
+$env:AZURE_AI_MODEL_DEPLOYMENT_NAME="gpt-5.4-mini"
+$env:FOUNDRY_TOOLBOX_MCP_SERVER_URL="https://your-foundry-service.services.ai.azure.com/api/projects/your-project/toolboxes/your-toolbox/mcp?api-version=v1"
