-# 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
-dotnet run
-```

-# What this sample demonstrates
-
-An [Agent Framework](https://github.com/microsoft/agent-framework) agent that loads its behavioral guidelines from [**Foundry Skills**](https://learn.microsoft.com/en-us/azure/foundry/agents/how-to/tools/skills) at startup, hosted using the **Responses protocol**. Skills are authored once as `SKILL.md` files, uploaded to your Foundry project through the Skills REST API, and downloaded by the agent on boot so updates ship without code changes.
-
-## How It Works
-
-### Authoring skills
-
-Each skill is a Markdown file with a YAML front matter block. This sample ships two source skills under [`skills/`](skills/):
-
-| Skill | Purpose |
-|---|---|
-| [`support-style`](skills/support-style/SKILL.md) | Voice, formatting, and signature rules for Contoso Outdoors support replies. |
-| [`escalation-policy`](skills/escalation-policy/SKILL.md) | When and how to escalate a customer ticket. |
-
-Each `SKILL.md` includes a unique `*-CANARY-*` token that the model is asked to echo, so you can prove the skill was loaded from Foundry (not hallucinated) by checking the response.
-
-> The `name` and `description` values in the YAML front matter must be **unquoted** — quoting them causes the Skills REST API to return HTTP 500 on import.
-
-### Uploading skills
-
-The sample includes a convenience provisioning step that checks whether each skill exists in Foundry and uploads it if not, gated behind the `PROVISION_SAMPLE_SKILLS=true` env var. **In production, skill provisioning is an external concern** — it is NOT the hosted agent's responsibility. A real deployment pipeline would provision skills separately (e.g., via a CI/CD step, a CLI script, or a management portal).
-
-The provisioning uses `ProjectAgentSkills.CreateSkillFromPackageAsync(directoryPath)` from the `Azure.AI.Projects.Agents` SDK. The method packages the `SKILL.md` file as a ZIP and uploads it to Foundry.
-
-### Downloading skills at agent startup
-
-[`Program.cs`](Program.cs) reads the comma-separated `SKILL_NAMES` env var and for each skill name downloads the ZIP archive from Foundry via `ProjectAgentSkills.DownloadSkillAsync(name)`, then unpacks it into a **separate runtime directory** at `downloaded_skills/<name>/` (kept distinct from the static `skills/` source folder).
-
-An [`AgentSkillsProvider`](../../../../../src/Microsoft.Agents.AI/Skills/AgentSkillsProvider.cs) is then built over `downloaded_skills/` and attached to the agent as a context provider. The provider follows the [Agent Skills](https://agentskills.io/) progressive-disclosure pattern:
-
-1. **Advertise** — skill names and descriptions are injected into the system prompt at session start (~100 tokens per skill).
-2. **Load** — the model calls the `load_skill` tool when it decides a skill is relevant to the user's turn, and the full `SKILL.md` body is returned.
-
-This means the model only pays the token cost for a skill's full body when it actually needs it, and updating a skill in Foundry + restarting the agent is enough to pick up the change — no code redeploy required.
-
-> **Note:** This sample supports instruction-only and resource-based skills. If your downloaded skills contain scripts, add a script runner when constructing the `AgentSkillsProvider`.
-
-### Agent Hosting
-
-The agent is hosted using the [Agent Framework](https://github.com/microsoft/agent-framework) with the Responses API hosting layer (`AddFoundryResponses` / `MapFoundryResponses`).
-
-## Prerequisites
-
-- An Azure AI Foundry project with a deployed model (e.g., `gpt-4o`)
-- Azure CLI logged in (`az login`)
-
-### Required RBAC
-
-Your identity (or the Managed Identity running the container in production) needs **Azure AI User** on the Foundry project scope. This single role covers both authoring skills and downloading them.
-
-## Running the Agent Host
-
-Set the required environment variables and run the sample with `dotnet run`:
-
-```bash
-export AZURE_AI_PROJECT_ENDPOINT="https://<account>.services.ai.azure.com/api/projects/<project>"
-export AZURE_AI_MODEL_DEPLOYMENT_NAME="gpt-4o"
-export SKILL_NAMES="support-style,escalation-policy"
-export PROVISION_SAMPLE_SKILLS="true"   # First run only — provisions skills to Foundry
-```
-
-Or in PowerShell:
-
-```powershell
-$env:SKILL_NAMES="support-style,escalation-policy"
-$env:PROVISION_SAMPLE_SKILLS="true"     # First run only — provisions skills to Foundry
-```
-
-You can also place these in a `.env` file next to `Program.cs` — see [`.env.example`](.env.example).
-
-On startup you should see:
-
-```text
-Skill 'support-style' already exists in Foundry.
-Skill 'escalation-policy' already exists in Foundry.
-Downloading skill 'support-style' from Foundry...
-Downloading skill 'escalation-policy' from Foundry...
-```
-
-The downloaded `SKILL.md` files land under `downloaded_skills/<name>/SKILL.md` next to the published output. This directory is recreated from scratch on every run, so deleting it manually is never necessary.
-
-## Interacting with the agent
-
-> Send a POST request to the server with a JSON body containing an `"input"` field to interact with the agent. For example:
-
-```bash
-curl -X POST http://localhost:8088/responses -H "Content-Type: application/json" -d '{"input": "Hi, I am Alex. I just want to confirm I can return my tent within 30 days."}'
-curl -X POST http://localhost:8088/responses -H "Content-Type: application/json" -d '{"input": "I want a $750 refund on Order #A-1042 right now or I am calling my lawyer."}'
-```
-
-| Prompt mentions | Skill that should drive the response |
-|---|---|
-| Routine return / shipping / care question | Model loads `support-style` (canary `STYLE-CANARY-3318`) — no escalation. |
-| Injury, legal threat, press, or refund > $500 | Model loads `escalation-policy` (canary `ESC-CANARY-7742`) **and** `support-style`. |
-
-Because skills are loaded on demand, the canary token in a response also proves the model actually invoked `load_skill` for the matching skill (not just saw its name in the advertised list).
-
-## Deploying the Agent to Foundry
-
-When deploying to Foundry, make sure `SKILL_NAMES` is set in your `azd` environment so it gets injected into the hosted container per [`agent.manifest.yaml`](agent.manifest.yaml):
-
-```bash
-azd env set SKILL_NAMES "support-style,escalation-policy"
-```
-
-The deployed agent's Managed Identity needs **Azure AI User** on the Foundry project to download skills at startup.
-
-> The `skills/` source folder is **not** deployed to Foundry — only the downloaded skills are used at runtime. The provisioning step must have been run against the same Foundry project before the agent can download the skills.

-# Contoso Outdoors Escalation Policy
-
-You must follow this escalation policy on every conversation.
-
-## Escalate immediately when the customer
-
-- Reports an injury, allergic reaction, or other safety incident.
-- Mentions legal action, regulators, or the press.
-- Has waited more than 14 days for a refund that was already approved.
-- Requests a refund larger than $500.
-
-## How to escalate
-
-1. Acknowledge the issue in one sentence.
-2. Tell the customer you are escalating to a senior specialist.
-3. Provide the escalation reference `ESC-CANARY-7742` and the SLA: a senior
-   specialist will reply within 1 business day.
-4. Do not promise a specific outcome (refund, replacement, compensation) on
-   escalated tickets — only the senior specialist can commit to one.
-
-## Do not escalate
-
-- Routine returns within the standard 30-day window.
-- Shipping status questions.
-- Product care and usage questions.

-# Contoso Outdoors Support Style

-- Warm, concise, and confident — never apologetic in a hand-wringing way.
-- Use the customer's name when it is known.
-- Sign every response with `— Contoso Outdoors Support`.
-
-## Formatting
-
-- Keep replies to 1–3 short paragraphs unless the customer asks for detail.
-- Use bullet lists only when enumerating concrete steps or options.
-- Always reference order numbers as `Order #<id>` (e.g. `Order #A-1042`).

-## Canary
