-name: Free runner disk space
-description: |
-  Reclaims disk space on GitHub-hosted Ubuntu runners by removing
-  pre-installed toolchains we do not use (Android SDK, GHC/Haskell,
-  CodeQL bundle), Docker images, and swap. Also relocates the
-  NuGet package cache to /mnt (which has ~75 GB free vs ~14 GB
-  on /). No-op on non-Linux runners.

-# Hosted-ToolboxMcpSkills
-
-A hosted agent that discovers **MCP-based skills from a Foundry Toolbox** and makes them available to the agent using `AgentSkillsProviderBuilder.UseMcpSkills(mcpClient)`.
-
-The `AgentSkillsProvider` is attached to the agent as a context provider and implements the [Agent Skills](https://agentskills.io/) progressive-disclosure pattern. When the agent is prompted, it discovers available skills in the Foundry Toolbox via the provider:
-
-1. **Advertise** - skill names and descriptions are injected into the system prompt so the agent knows what is available.
-2. **Load** - when the agent decides a skill is relevant, it retrieves the full skill body with detailed instructions via the provider.
-3. **Read resources** - if a skill includes supplementary content (reference documents, assets), the agent reads them on demand via the provider.
-
-This way the full skill body and resources are only loaded when the agent actually needs them, reducing token usage.
-
-## Prerequisites
-
- [.NET 10 SDK](https://dotnet.microsoft.com/download/dotnet/10.0)
- An Azure AI Foundry project with a deployed model (e.g., `gpt-5`)
- A Foundry Toolbox already configured with skills provisioned
- Azure CLI logged in (`az login`)
-
-## Configuration
-
-Copy the template and fill in your values:
-
-```bash
-cp .env.example .env
-```
-
-Edit `.env` and set your Azure AI Foundry project endpoint and toolbox name:
-
-```env
-AZURE_AI_PROJECT_ENDPOINT=https://<your-account>.services.ai.azure.com/api/projects/<your-project>
-ASPNETCORE_URLS=http://+:8088
-ASPNETCORE_ENVIRONMENT=Development
-AZURE_AI_MODEL_DEPLOYMENT_NAME=gpt-5
-FOUNDRY_TOOLBOX_NAME=my-toolbox
-```
-
-> **Note:** `.env` is gitignored. The `.env.example` template is checked in as a reference.
-
-## Running directly (contributors)
-
-This project uses `ProjectReference` to build against the local Agent Framework source.
-
-```bash
-cd dotnet/samples/04-hosting/FoundryHostedAgents/responses/Hosted-ToolboxMcpSkills
-dotnet run
-```
-
-The agent will start on `http://localhost:8088`.
-
-### Test it
-
-Using the Azure Developer CLI:
-
-```bash
-azd ai agent invoke --local "What skills do you have available?"
-```
-
-## Running with Docker
-
-Since this project uses `ProjectReference`, use `Dockerfile.contributor` which takes a pre-published output.
-
-### 1. Publish for the container runtime (Linux Alpine)
-
-```bash
-dotnet publish -c Debug -f net10.0 -r linux-musl-x64 --self-contained false -o out
-```
-
-### 2. Build the Docker image
-
-```bash
-docker build -f Dockerfile.contributor -t hosted-toolbox-mcp-skills .
-```
-
-### 3. Run the container
-
-Generate a bearer token on your host and pass it to the container:
-
-```bash
-# Generate token (expires in ~1 hour)
-export AZURE_BEARER_TOKEN=$(az account get-access-token --resource https://ai.azure.com --query accessToken -o tsv)
-
-# Run with token
-docker run --rm -p 8088:8088 \
-  -e AGENT_NAME=hosted-toolbox-mcp-skills \
-  -e AZURE_BEARER_TOKEN=$AZURE_BEARER_TOKEN \
-  --env-file .env \
-  hosted-toolbox-mcp-skills
-```
-
-> **Note:** `AGENT_NAME` is passed via `-e` to simulate the platform injection. `AZURE_BEARER_TOKEN` provides Azure credentials to the container (tokens expire after ~1 hour). The `.env` file provides the remaining configuration.
-
-### 4. Test it
-
-Using the Azure Developer CLI:
-
-```bash
-azd ai agent invoke --local "What skills do you have available?"
-```
-
-## NuGet package users
-
-If you are consuming the Agent Framework as a NuGet package (not building from source), use the standard `Dockerfile` instead of `Dockerfile.contributor`. See the commented section in `HostedToolboxMcpSkills.csproj` for the `PackageReference` alternative.
