+# SessionFilesClient
+
+A thin chat REPL that connects to a deployed [`Hosted-Files`](../../Hosted-Files/) agent via `FoundryAgent` and lets you ask questions whose answers come from the files bundled with that agent. Same shape as [`SimpleAgent`](../SimpleAgent/) — point it at an `AGENT_ENDPOINT`, build a `FoundryAgent`, run.
+
+The agent's container-side `ListFiles` and `ReadFile` tools surface the bundled file contents to the model. The client knows nothing about files; that is entirely the agent's concern.
+
+## Prerequisites
+
+- [.NET 10 SDK](https://dotnet.microsoft.com/download/dotnet/10.0)
+- A running [`Hosted-Files`](../../Hosted-Files/) agent (locally via `dotnet run` or deployed to Foundry)
+- Azure CLI logged in (`az login`)
+
+## Configuration
+
+```env
+FOUNDRY_PROJECT_ENDPOINT=https://<host>/api/projects/<project>
+AZURE_AI_AGENT_NAME=hosted-files
+```
+
+Both are required. `FOUNDRY_PROJECT_ENDPOINT` is the Foundry project endpoint URL and `AZURE_AI_AGENT_NAME` is the registered server-side agent name. The sample builds the per-agent OpenAI endpoint URL from these.
+
+## Run
+
+```bash
+cd dotnet/samples/04-hosting/FoundryHostedAgents/responses/Using-Samples/SessionFilesClient
+$env:FOUNDRY_PROJECT_ENDPOINT = "http://localhost:8088/api/projects/local"
+$env:AZURE_AI_AGENT_NAME = "hosted-files"
+dotnet run
+```
+
+## End-to-end demo
+
+With the [`Hosted-Files`](../../Hosted-Files/) agent running:
+
+```text
+══════════════════════════════════════════════════════════
+Session Files Client
+Connected to: http://localhost:8088/
+Try: "Give me the total revenue in the contoso file."
+Type a message or 'quit' to exit
+══════════════════════════════════════════════════════════
+
+You> Give me the total revenue in the contoso file.
+Agent> The contoso file reports total revenue of "$1,482.6M".
+
+You> quit
+Goodbye!
+```
+
+The agent looked at its bundled files via `ListFiles`, picked `contoso_q1_2026_report.txt`, called `ReadFile`, and quoted the figure verbatim. The client only sent a chat prompt.
