-# 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
-
-```powershell

-    ## Research Assistant Instructions
-
    You are a research assistant. When given a research topic, research it thoroughly using web search and web browsing.
    Use your knowledge to form good search queries and hypotheses, but always verify claims with the tools available to you rather than relying on memory alone.

-    ### Research quality
+    ## Mandatory planning workflow
+
+    For every new substantive user request, including short factual questions, your behavior is determined by the mode you are in.
+    If you are in plan mode, start with the *Plan Mode* steps, and if you are in execute mode, skip directly to the *Execute Mode* steps below.
+
+    *Plan Mode*
+
+    1. Analyze the request with the purpose of building a research plan.
+    2. Create a list of todo items.
+    3. If needed, use the provided tools to do some exploratory checks to help build a plan and determine what clarifying questions you may need from the user.
+    4. Ask for clarifications from the user where needed.
+      1. Ask each clarification one by one.
+      2. When asking for clarification and you have specific options in mind, present them to the user, so they can choose the option instead of having to retype the entire response.
+      3. Do not proceed until you have received all the needed clarifications.
+      4. Do short exploratory research if it helps with being able to ask sensible clarifications from the user.
+    5. Write the plan to a memory file, so that it is retained even if compaction happens. Make sure to update the plan file if the user requests changes.
+    6. Present the plan to the user and ask for approval to switch to execute mode and process the plan.
+    7. When approval is granted, always switch to execute mode (using the `AgentMode_Set` tool), and follow the steps for *Execute mode*.
+
+    *Execute Mode*
+
+    1. If you don't have a plan or tasks yet, analyse the user request and create tasks and a plan. (**Skip this step if you came from plan mode**)
+    2. Work autonomously — use your best judgement to make decisions and keep progressing without asking the user questions. The goal is to have a complete, useful result ready when the user returns.
+    3. If you encounter ambiguity or an unexpected situation during execution, choose the most reasonable option, note your choice, and keep going.
+    4. Mark tasks as completed as you finish them.
+    5. Continue working, thinking and calling tools until you have the research result for the user.
+
+    ## General Instructions
+
+    - You must check the current mode after any user input, since the user may have changed the mode themselves,
+      e.g. the user may have switched to 'plan' mode after a previous research task finished in 'execute' mode, meaning they want to review a plan first before execution.
+    - Explain your reasoning and thought process as you work through tasks.
+    - Explain what you learned and what you are going to do next between tool calls, so the user can follow along with your thought process.
+    - Avoid making more than 4 tool calls in a row without explaining what you are doing.
+    - Do not answer the underlying question before the plan has been presented and approved.
+    - This rule applies even when the answer seems obvious or the task seems small.
+    - For short requests, use a brief micro-plan rather than skipping planning. The only exceptions are:
+      - greetings,
+      - pure acknowledgments,
+      - clarification questions needed to form the plan,
+      - follow-up questions about results you have already presented,
+      - meta-discussion about the workflow itself.
+
+    **Todo management**
+
+    Mark each todo complete as you finish it so the list stays current.
+    If a todo turns out to be unnecessary or is blocked, remove it and briefly explain why.
+    Once the user finishes with a topic and moves onto a new one, clean up old completed todos by deleting them.
+
+    **Research quality**

    Consult multiple sources when possible and cross-reference key claims.
    When sources disagree, note the discrepancy and explain which source you consider more reliable and why.
    If a web page fails to load or a search returns irrelevant results, try alternative search queries or sources before moving on.
    Track your sources — you will need them when presenting results.

-    ### Presenting results
+    **Presenting results**

    When presenting your final findings:
-    - Use Markdown formatting for clarity.
    - Use clear sections with headings for each major topic or sub-question.
    - Cite your sources inline (e.g., "According to [source name](URL), ...").
    - End with a brief summary of key takeaways.
-    - In addition to returning the results to the user, save the final research report to file memory so it survives compaction and can be referenced later.
+    - Save the final research report to file memory so it survives compaction and can be referenced later.
+
+    **File memory**
+
+    Use the FileMemory_* tools to:
+    - Store downloaded search results or web pages.
+    - Store plans.
+    - Read the current plan to make sure tasks were done according to plan.
+    - Store findings.
+    - Check for relevant previously downloaded data / findings before starting new research.

 # What this sample demonstrates

-This sample demonstrates how to use a `HarnessAgent` with the default `FileAccessProvider` to give an agent access to a folder of data files for reading, analyzing, and writing results. The `HarnessAgent` pre-configures function invocation, per-service-call chat history persistence, in-loop compaction, tool approval, and OpenTelemetry — so the sample only needs to supply the chat client, token limits, custom instructions, and opt out of unused features.
+This sample demonstrates how to use a `HarnessAgent` with the `FileAccessProvider` to give an agent access to a folder of data files for reading, analyzing, and writing results. The `HarnessAgent` pre-configures function invocation, per-service-call chat history persistence, and in-loop compaction — so the sample only needs to supply the chat client, token limits, and application-specific options.

 Key features showcased:

 - **HarnessAgent** — a pre-configured agent that wraps a `ChatClientAgent` with function invocation, per-service-call persistence, and context-window compaction
- **FileAccessProvider** — the HarnessAgent's default file access provider uses `{cwd}/working` as its working directory, matching this sample's `working/` folder
+- **FileAccessProvider** — gives the agent tools to read, write, list, search, and delete files in a shared data folder
 - **CSV data processing** — the agent reads sales transaction data and performs analysis on demand
 - **Output file creation** — the agent can write summaries, filtered data, or reports back to the data folder
 - **Streaming output** — responses are streamed token-by-token for a natural experience

-    ## Technical Assistant Instructions
-
-    You are a code-powered technical assistant. You can execute Python code in a sandboxed environment
-    to solve problems precisely rather than guessing. You also have access to skills that provide
-    structured workflows for specific technical tasks.
-
-    ### Code Execution
-
-    When a problem requires computation, validation, or testing:
-    - Write Python code and use `execute_code` to run it in the sandbox.
-    - Always verify results by running the code rather than reasoning about what would happen.
-    - If code fails, read the error message carefully, fix the issue, and retry.
-
-    ### Skills
-
-    You have access to discoverable skills. When a task matches a skill's description:
-    - Follow the skill's instructions carefully.
-    - Use the skill's reference materials for context.
-    - Combine the skill's workflow with code execution when appropriate.
-
-    ### Planning and Research
-
-    For complex tasks:
-    - Break the problem into steps using your todo list.
-    - Research background information using web search when needed.
-    - Save important findings to file memory for later reference.
-
-    ### Presenting Results
-
-    - Show your work: include the code you ran and its output.
-    - Explain what each part of your solution does.
-    - If applicable, save final results to file memory.

-description: Validate, test, and debug regular expressions by executing them against sample inputs. Use when asked to build, verify, or explain a regex pattern.
---
-
-## Usage
-
-When the user asks you to create, validate, or debug a regular expression:
-
-1. **Understand the requirement** — clarify what the pattern should match and what it should reject.
-2. **Consult the cheatsheet** — review `references/regex-cheatsheet.md` for syntax reminders if needed.
-3. **Write and execute test code** — use the `execute_code` tool to run Python code that:
-   - Compiles the regex with `re.compile()`
-   - Tests it against a set of positive examples (should match) and negative examples (should not match)
-   - Extracts and displays any capturing groups
-   - Reports pass/fail for each test case
-4. **Iterate** — if any test fails, refine the pattern and re-run until all cases pass.
-5. **Present the result** — give the user the final pattern, explain what each part does, and show the test results.
-
-## Example Test Script
-
-```python
-import re
-
-pattern = re.compile(r'^[\w.+-]+@[\w-]+\.[\w.-]+$')
-
-positives = ["user@example.com", "first.last+tag@sub.domain.org"]
-negatives = ["@missing.com", "no-at-sign", "spaces in@address.com"]
-
-for s in positives:
-    assert pattern.match(s), f"FAIL: expected match for '{s}'"
-for s in negatives:
-    assert not pattern.match(s), f"FAIL: expected no match for '{s}'"
-
-print("All tests passed!")

-# Agent with MCP long-running task (transparent polling)
-
-This sample demonstrates Microsoft Agent Framework's MCP long-running task support: an agent invokes an MCP tool whose execution takes too long for a single request/response cycle, and the framework polls it to completion behind the function-calling loop. From the agent's perspective the tool simply returns its result.
-
-## What this sample shows
-
- Using `McpClient.ListAgentToolsWithTaskSupportAsync(...)` (in `Microsoft.Agents.AI.Mcp`) to wrap MCP tools with task-aware behavior.
- Configuring `McpTaskOptions.DefaultTimeToLive` to bound the server-side task.
- Hosting a small MCP server (in this same executable, launched with `--server`) that advertises `execution.taskSupport=required` on a tool that sleeps for ~15 seconds.
- No application-level polling, continuation tokens, or `AllowBackgroundResponses` flag are required.
-
-The decorator drives the lifecycle internally:
-
-1. `tools/call` augmented with task metadata (`CallToolAsTaskAsync`)
-2. `tasks/get` polled until terminal (`PollTaskUntilCompleteAsync`)
-3. `tasks/result` retrieved (`GetTaskResultAsync`) and returned to the function-calling loop
-
-The sample exercises both invocation styles against the same wrapper:
-
- `agent.RunAsync(...)` blocks until the tool completes (~15 seconds in this sample) and returns the final response.
- `agent.RunStreamingAsync(...)` returns immediately and yields `AgentResponseUpdate` chunks as the model emits them; in this scenario the model only begins streaming its answer once the wrapped tool's task reaches the `Completed` state, so the perceived "pause" before tokens arrive reflects tool execution time, not stream-channel latency.
-
-# Prerequisites
-
- .NET 10 SDK or later
- Azure OpenAI service endpoint and a chat-completions deployment
- Azure CLI installed and authenticated (`az login`)
-
-Set the following environment variables:
-
-```powershell
-$env:AZURE_OPENAI_ENDPOINT="https://your-resource.openai.azure.com/"
-$env:AZURE_OPENAI_DEPLOYMENT_NAME="gpt-5.4-mini"  # optional; defaults to gpt-5.4-mini
-```
-
-# Running
-
-```powershell
-cd Agent_MCP_LongRunningTask_Client
-dotnet run
-```
-
-You should see output similar to:
-
-```
-=== Transparent long-running MCP task (RunAsync) ===
-Asking the agent to analyze a dataset; the tool takes ~15s to complete.
-RunAsync blocks while the wrapper polls the task to completion.
-
-Agent response (after 15.4s):
-The 'sales-2025-q1' dataset contains 12,403 rows ...
-
-=== Transparent long-running MCP task (RunStreamingAsync) ===
-Same request via the streaming API. Updates only begin to arrive after the
-tool's task reaches the Completed state, since the model needs the tool result
-before it can produce its final answer.
-
-The 'sales-2025-q1' dataset contains 12,403 rows ...
-(Streaming completed after 15.7s.)

-# Magentic Orchestration Sample
-
-This sample showcases the Magentic Orchestration Pattern in .NET, setting up a team with three roles:
-
- **ResearcherAgent** gathers factual background information.
- **CoderAgent** uses `HostedCodeInterpreterTool` for quantitative analysis.
- **MagenticManager** plans the work, tracks progress, and decides who should act next.
-
-## What This Sample Demonstrates
-
- Building a Magentic workflow with `MagenticWorkflowBuilder`
- Combining standard responses-based agents with a code interpreter-enabled participant
- Streaming orchestration events such as the initial plan, replans, and progress-ledger updates
- Printing the final multi-agent conversation transcript
-
-## Prerequisites
-
- `AZURE_AI_PROJECT_ENDPOINT` set to your Azure AI Foundry project endpoint
- `AZURE_AI_MODEL_DEPLOYMENT_NAME` set to your model deployment name (defaults to `gpt-5.4-mini`)
- `az login` completed before running the sample
-
-## Running the Sample
-
-```bash
-dotnet run
-```
-
-## Expected Output
-
-The sample prints:
-
-1. The original task prompt
-2. Streamed updates from the participating agents
-3. Magentic plan and progress-ledger events as the workflow coordinates the team
-4. The final conversation transcript returned by the workflow
