- Low quality/simple images: Fewer partials (generation completes quickly)
- You may receive fewer partial images than requested if generation is fast

The following sample demonstrates a comprehensive 4-step workflow with multiple executors
that process, detect spam, and handle email messages. This workflow illustrates
complex branching logic with human-in-the-loop approval and realistic processing delays.
Workflow Steps:
1. Email Preprocessor - Cleans and prepares the email
2. Content Analyzer - Analyzes email content and structure
3. Spam Detector - Determines if the message is spam
4a. Spam Handler - Processes spam messages (quarantine, log, remove)
4b. Message Responder - Handles legitimate messages (validate, respond)
5. Final Processor - Completes the workflow with logging and cleanup

This getting-started sample shows how to attach Microsoft Purview policy evaluation to an Agent Framework `ChatAgent` using the **middleware** approach.
**What this sample demonstrates:**
1. Configure an Azure OpenAI chat client
2. Add Purview policy enforcement middleware (`PurviewPolicyMiddleware`)
3. Run a short conversation and observe prompt / response blocking behavior
3. Add Purview policy enforcement at the chat client level (`PurviewChatPolicyMiddleware`)
4. Implement a custom cache provider for advanced caching scenarios
5. Run conversations and observe prompt / response blocking behavior
**Note:** Caching is **automatic** and enabled by default with sensible defaults (30-minute TTL, 200MB max size).

## 4. How It Works
The sample demonstrates three different scenarios:
### A. Agent Middleware (`run_with_agent_middleware`)
1. Builds an Azure OpenAI chat client (using the environment endpoint / deployment)
2. Chooses credential mode (certificate vs interactive)
3. Creates `PurviewPolicyMiddleware` with `PurviewSettings`
4. Injects middleware into the agent at construction
5. Sends two user messages sequentially
6. Prints results (or policy block messages)
7. Uses default caching automatically
### B. Chat Client Middleware (`run_with_chat_middleware`)
1. Creates a chat client with `PurviewChatPolicyMiddleware` attached directly
2. Policy evaluation happens at the chat client level rather than agent level
3. Demonstrates an alternative integration point for Purview policies
4. Uses default caching automatically
### C. Custom Cache Provider (`run_with_custom_cache_provider`)
1. Implements the `CacheProvider` protocol with a custom class (`SimpleDictCacheProvider`)
2. Shows how to add custom logging and metrics to cache operations
3. The custom provider must implement three async methods:
- `async def get(self, key: str) -> Any | None`
- `async def set(self, key: str, value: Any, ttl_seconds: int | None = None) -> None`
- `async def remove(self, key: str) -> None`
**Policy Behavior:**
Prompt blocks set a system-level message: `Prompt blocked by policy` and terminate the run early. Response blocks rewrite the output to `Response blocked by policy`.

# Tools Examples
This folder contains examples demonstrating how to use AI functions (tools) with the Agent Framework. AI functions allow agents to interact with external systems, perform computations, and execute custom logic.
## Examples
| File | Description |
|------|-------------|
| [`ai_function_declaration_only.py`](ai_function_declaration_only.py) | Demonstrates how to create function declarations without implementations. Useful for testing agent reasoning about tool usage or when tools are defined elsewhere. Shows how agents request tool calls even when the tool won't be executed. |
| [`ai_function_from_dict_with_dependency_injection.py`](ai_function_from_dict_with_dependency_injection.py) | Shows how to create AI functions from dictionary definitions using dependency injection. The function implementation is injected at runtime during deserialization, enabling dynamic tool creation and configuration. Note: This serialization/deserialization feature is in active development. |
| [`ai_function_recover_from_failures.py`](ai_function_recover_from_failures.py) | Demonstrates graceful error handling when tools raise exceptions. Shows how agents receive error information and can recover from failures, deciding whether to retry or respond differently based on the exception. |
| [`ai_function_with_approval.py`](ai_function_with_approval.py) | Shows how to implement user approval workflows for function calls without using threads. Demonstrates both streaming and non-streaming approval patterns where users can approve or reject function executions before they run. |
| [`ai_function_with_approval_and_threads.py`](ai_function_with_approval_and_threads.py) | Demonstrates tool approval workflows using threads for automatic conversation history management. Shows how threads simplify approval workflows by automatically storing and retrieving conversation context. Includes both approval and rejection examples. |
| [`ai_function_with_max_exceptions.py`](ai_function_with_max_exceptions.py) | Shows how to limit the number of times a tool can fail with exceptions using `max_invocation_exceptions`. Useful for preventing expensive tools from being called repeatedly when they keep failing. |
| [`ai_function_with_max_invocations.py`](ai_function_with_max_invocations.py) | Demonstrates limiting the total number of times a tool can be invoked using `max_invocations`. Useful for rate-limiting expensive operations or ensuring tools are only called a specific number of times per conversation. |
| [`ai_functions_in_class.py`](ai_functions_in_class.py) | Shows how to use `ai_function` decorator with class methods to create stateful tools. Demonstrates how class state can control tool behavior dynamically, allowing you to adjust tool functionality at runtime by modifying class properties. |
## Key Concepts
### AI Function Features
- **Function Declarations**: Define tool schemas without implementations for testing or external tools
- **Dependency Injection**: Create tools from configurations with runtime-injected implementations
- **Error Handling**: Gracefully handle and recover from tool execution failures
- **Approval Workflows**: Require user approval before executing sensitive or important operations
- **Invocation Limits**: Control how many times tools can be called or fail
- **Stateful Tools**: Use class methods as tools to maintain state and dynamically control behavior
### Common Patterns
#### Basic Tool Definition
```python
from agent_framework import ai_function
from typing import Annotated
@ai_function
def my_tool(param: Annotated[str, "Description"]) -> str:
"""Tool description for the AI."""
return f"Result: {param}"
```
#### Tool with Approval
```python
@ai_function(approval_mode="always_require")
def sensitive_operation(data: Annotated[str, "Data to process"]) -> str:
"""This requires user approval before execution."""
return f"Processed: {data}"
```
#### Tool with Invocation Limits
```python
@ai_function(max_invocations=3)
def limited_tool() -> str:
"""Can only be called 3 times total."""
return "Result"
@ai_function(max_invocation_exceptions=2)
def fragile_tool() -> str:
"""Can only fail 2 times before being disabled."""
return "Result"
```
#### Stateful Tools with Classes
```python
class MyTools:
def __init__(self, mode: str = "normal"):
self.mode = mode
def process(self, data: Annotated[str, "Data to process"]) -> str:
"""Process data based on current mode."""
if self.mode == "safe":
return f"Safely processed: {data}"
return f"Processed: {data}"
# Create instance and use methods as tools
tools = MyTools(mode="safe")
agent = client.create_agent(tools=tools.process)
# Change behavior dynamically
tools.mode = "normal"
```
### Error Handling
When tools raise exceptions:
1. The exception is captured and sent to the agent as a function result
2. The agent receives the error message and can reason about what went wrong
3. The agent can retry with different parameters, use alternative tools, or explain the issue to the user
4. With invocation limits, tools can be disabled after repeated failures
### Approval Workflows
Two approaches for handling approvals:
1. **Without Threads**: Manually manage conversation context, including the query, approval request, and response in each iteration
2. **With Threads**: Thread automatically manages conversation history, simplifying the approval workflow
## Usage Tips
- Use **declaration-only** functions when you want to test agent reasoning without execution
- Use **dependency injection** for dynamic tool configuration and plugin architectures
- Implement **approval workflows** for operations that modify data, spend money, or require human oversight
- Set **invocation limits** to prevent runaway costs or infinite loops with expensive tools
- Handle **exceptions gracefully** to create robust agents that can recover from failures
- Use **class-based tools** when you need to maintain state or dynamically adjust tool behavior at runtime
## Running the Examples
Each example is a standalone Python script that can be run directly:
```bash
uv run python ai_function_with_approval.py
```
Make sure you have the necessary environment variables configured (like `OPENAI_API_KEY` or Azure credentials) before running the examples.

This sample demonstrates how to create a workflow that combines an AI agent executor
with a custom executor.
The workflow consists of two stages:
1. An AI agent with code interpreter capabilities that generates and executes Python code
2. An evaluator executor that reviews the agent's output and provides a final assessment
Key concepts demonstrated:
- Creating an AI agent with tool capabilities (HostedCodeInterpreterTool)
- Building workflows using WorkflowBuilder with an agent and a custom executor
- Using the @handler decorator in the executor to process AgentExecutorResponse from the agent
- Connecting workflow executors with edges to create a processing pipeline
- Yielding final outputs from terminal executors
- Non-streaming workflow execution and result collection
Prerequisites:
- Azure AI services configured with required environment variables
- Azure CLI authentication (run 'az login' before executing)
- Basic understanding of async Python and workflow concepts

Sample: Agents in a workflow with AI functions requiring approval
This sample creates a workflow that automatically replies to incoming emails.
If historical email data is needed, it uses an AI function to read the data,
which requires human approval before execution.
This sample works as follows:
1. An incoming email is received by the workflow.
2. The EmailPreprocessor executor preprocesses the email, adding special notes if the sender is important.
3. The preprocessed email is sent to the Email Writer agent, which generates a response.
4. If the agent needs to read historical email data, it calls the read_historical_email_data AI function,
which triggers an approval request.
5. The sample automatically approves the request for demonstration purposes.
6. Once approved, the AI function executes and returns the historical email data to the agent.
7. The agent uses the historical data to compose a comprehensive email response.
8. The response is sent to the conclude_workflow_executor, which yields the final response.
Purpose:
Show how to integrate AI functions with approval requests into a workflow.
Demonstrate:
- Creating AI functions that require approval before execution.
- Building a workflow that includes an agent and executors.
- Handling approval requests during workflow execution.
Prerequisites:
- Azure AI Agent Service configured, along with the required environment variables.
- Authentication via azure-identity. Use AzureCliCredential and run az login before executing the sample.
- Basic familiarity with WorkflowBuilder, edges, events, RequestInfoEvent, and streaming runs.

"""Sample: Handoff workflow with return-to-previous routing enabled.
This interactive sample demonstrates the return-to-previous feature where user inputs
route directly back to the specialist currently handling their request, rather than
always going through the coordinator for re-evaluation.
Routing Pattern (with return-to-previous enabled):
User -> Coordinator -> Technical Support -> User -> Technical Support -> ...
Routing Pattern (default, without return-to-previous):
User -> Coordinator -> Technical Support -> User -> Coordinator -> Technical Support -> ...
This is useful when a specialist needs multiple turns with the user to gather
information or resolve an issue, avoiding unnecessary coordinator involvement.
Specialist-to-Specialist Handoff:
When a user's request changes to a topic outside the current specialist's domain,
the specialist can hand off DIRECTLY to another specialist without going back through
the coordinator:
User -> Coordinator -> Technical Support -> User -> Technical Support (billing question)
-> Billing -> User -> Billing ...
Example Interaction:
1. User reports a technical issue
2. Coordinator routes to technical support specialist
3. Technical support asks clarifying questions
4. User provides details (routes directly back to technical support)
5. Technical support continues troubleshooting with full context
6. Issue resolved, user asks about billing
7. Technical support hands off DIRECTLY to billing specialist
8. Billing specialist helps with payment
9. User continues with billing (routes directly to billing)
Prerequisites:
- `az login` (Azure CLI authentication)
- Environment variables configured for AzureOpenAIChatClient (AZURE_OPENAI_ENDPOINT, etc.)
Usage:
Run the script and interact with the support workflow by typing your requests.
Type 'exit' or 'quit' to end the conversation.
Key Concepts:
- Return-to-previous: Direct routing to current agent handling the conversation
- Current agent tracking: Framework remembers which agent is actively helping the user
- Context preservation: Specialist maintains full conversation context
- Domain switching: Specialists can hand back to coordinator when topic changes
