# Samples Structure & Design Choices — Python

> This file documents the structure and conventions of the Python samples so that

|
||
## Design principles
|
||
|
||
1. **Progressive complexity**: Sections 01→05 build from "hello world" to
|
||
production. Within 01-get-started, files are numbered 01–06 and each step
|
||
adds exactly one concept.
|
||
|
||
2. **One concept per file** in 01-get-started and flat files in 02-agents/.
|
||
|
||
3. **Workflows preserved**: 03-workflows/ keeps the upstream folder names
|
||
and file names intact. Do not rename or restructure workflow samples.
|
||
|
||
4. **Single-file for 01-03**: Only 04-hosting and 05-end-to-end use multi-file
|
||
projects with their own README.
|
||
|
||
## Default provider
|
||
|
||
All canonical samples (01-get-started) use **Azure AI Foundry project-backed chat** via `FoundryChatClient`
|
||
with an Azure AI Foundry project endpoint:
|
||
|
||
```python
|
||
import os
|
||
from agent_framework.foundry import FoundryChatClient
|
||
from azure.identity import AzureCliCredential
|
||
|
||
credential = AzureCliCredential()
|
||
client = FoundryChatClient(
|
||
project_endpoint=os.environ["FOUNDRY_PROJECT_ENDPOINT"],
|
||
model=os.environ["FOUNDRY_MODEL"],
|
||
credential=credential,
|
||
)
|
||
agent = client.as_agent(name="...", instructions="...")
|
||
```
|
||
|
||
Environment variables:
|
||
- `FOUNDRY_PROJECT_ENDPOINT` — Your Azure AI Foundry project endpoint
|
||
- `FOUNDRY_MODEL` — Model deployment name (e.g. gpt-4o)
|
||
|
||
For authentication, run `az login` before running samples.
|
||
|
||
## Snippet tags for docs integration
|
||
|
||
Samples embed named snippet regions for future `:::code` integration:
|
||
|
||
```python
|
||
# <snippet_name>
|
||
code here
|
||
# </snippet_name>
|
||
```
|
||
|
||
## Package install
|
||
|
||
```bash
|
||
pip install agent-framework --pre
|
||
```
|
||
|
||
The `--pre` flag is needed during preview. `openai` is a core dependency.
|
||
|
||
## Current API notes
|
||
|
||
- `Agent` class renamed from `ChatAgent` (use `from agent_framework import Agent`)
|
||
- `Message` class renamed from `ChatMessage` (use `from agent_framework import Message`)
|
||
- `call_next` in middleware takes NO arguments: `await call_next()` (not `await call_next(context)`)
|
||
- Prefer `client.as_agent(...)` over `Agent(client=client, ...)`
|
||
- Tool methods on hosted tools are now functions, not classes (e.g. `hosted_mcp_tool(...)` not `HostedMCPTool(...)`)
