Fix for LLMCallEvent failing to log "tools" passed to
BaseOpenAIChatCompletionClient in
autogen_ext.models.openai._openai_client.BaseOpenAIChatCompletionClient
This bug creates problems inspecting why a certain tool was selected/not
selected by the LLM as the list of tools available to the LLM is not
present in the logs
## Why are these changes needed?
Added "tools" to the LLMCallEvent to log tools available to the LLM as
these were being missed causing difficulties during debugging LLM tool
calls.

## Why are these changes needed?
This change introduces support for dynamic formatting of tool call
summary messages by allowing a user-defined
`tool_call_summary_format_fct`. Instead of relying solely on a static
string template, this function enables runtime generation of summary
messages based on the specific tool call and its result. This provides
greater flexibility and cleaner integration without introducing any
breaking changes.
### My Use Case / Problem
In my use case, I needed concise summaries for successful tool calls and
detailed messages for failures. The existing static summary string
didn't allow conditional formatting, which led to overly verbose success
messages or inconsistent failure outputs. This change allows customizing
summaries per result type, solving that limitation cleanly.

Some fixes with the AnthropicBedrockChatCompletionClient
- Ensure `AnthropicBedrockChatCompletionClient` exported and can be
imported.
- Update the BedrockInfo keys serialization - client argument can be
string (similar to api key in this ) but exported config should be
Secret
- Replace `AnthropicBedrock` with `AsyncAnthropicBedrock` : client
should be async to work with the ag stack and the BaseAnthropicClient it
inherits from
- Improve `AnthropicBedrockChatCompletionClient` docstring to use the
correct client arguments rather than serialized dict format.
Expect
```python
from autogen_ext.models.anthropic import AnthropicBedrockChatCompletionClient, BedrockInfo
from autogen_core.models import UserMessage, ModelInfo
async def main():
anthropic_client = AnthropicBedrockChatCompletionClient(
model="anthropic.claude-3-5-sonnet-20240620-v1:0",
temperature=0.1,
model_info=ModelInfo(vision=False, function_calling=True,
json_output=False, family="unknown", structured_output=True),
bedrock_info=BedrockInfo(
aws_access_key="<aws_access_key>",

Added `flush=True` to the `aprint` call when handling

When handling `ModelClientStreamingChunkEvent` message, streaming chunks
weren't guaranteed to be displayed immediately, as Python's stdout might
buffer output without an explicit flush instruction. This could cause
visual delays between when `chunk_event` objects are added to the
message queue and when users actually see the content rendered in the
console.

## Why are these changes needed?
❗ Before
Previously, GraphFlow.__init__() modified the inner_chats and
termination_condition for internal execution logic (e.g., constructing
_StopAgent or composing OrTerminationCondition).
However, these modified values were also used during dump_component(),
meaning the serialized config no longer matched the original inputs.
As a result:
1. dump_component() → load_component() → dump_component() produced
non-idempotent configs.
2. Internal-only constructs like _StopAgent were mistakenly serialized,
even though they should only exist in runtime.
⸻
✅ After
This patch changes the behavior to:
• Store original inner_chats and termination_condition as-is at
initialization.
• During to_config(), serialize only the original unmodified versions.
• Avoid serializing _StopAgent or other dynamically built agents.
• Ensure deserialization (from_config) produces a logically equivalent
object without additional nesting or duplication.
This ensures that:
• GraphFlow.dump_component() → load_component() round-trip produces
consistent, minimal configs.
• Internal execution logic and serialized component structure are
properly separated.

### Add Directed Graph-based Group Chat Execution Engine
(`DiGraphGroupChat`)
This PR introduces a new graph-based execution framework for Autogen
agent teams, located under `autogen_agentchat/teams/_group_chat/_graph`.
**Key Features:**
- **`DiGraphGroupChat`**: A new group chat implementation that executes
agents based on a user-defined directed graph (DAG or cyclic with exit
conditions).
- **`AGGraphBuilder`**: A fluent builder API to programmatically
construct graphs.
- **`MessageFilterAgent`**: A wrapper to restrict what messages an agent
sees before invocation, supporting per-source and per-position
filtering.
**Capabilities:**
- Supports sequential, parallel, conditional, and cyclic workflows.
- Enables fine-grained control over both execution order and message
context.
- Compatible with existing Autogen agents and runtime interfaces.
**Tests:**
- Located in `autogen_agentchat/tests/test_group_chat_graph.py`
- Includes unit and integration tests covering:
- Graph validation
- Execution paths
- Conditional routing
- Loops with exit conditions
- Message filtering
Let me know if anything needs refactoring or if you'd like the
components split further.

## Why are these changes needed?
Starting from AutoGen v0.5.5, tools are internally managed through
`StaticWorkbench`.
However, both tools and workbench were being serialized and
deserialized, which caused conflicts during deserialization:
• When both are restored, the constructor raises:
```
ValueError: Tools cannot be used with a workbench.
```
The changes address this issue by:
1. Removing tools from serialization/deserialization:
• tools are now considered internal state of `StaticWorkbench`, and are
no longer serialized.
• Only workbench is serialized, ensuring consistency and avoiding
duplication.
2. Ensuring logical integrity:
• Since tools are not used directly after initialization, persisting
them separately serves no functional purpose.
• This avoids scenarios where both are populated, violating constructor
constraints.
Summary:
This change prevents tools/workbench conflicts by fully delegating tool
management to `StaticWorkbench` and avoiding unnecessary persistence of
tools themselves.

## Why are these changes needed?
*Problem*
Previously, in `DockerCommandLineCodeExecutor`, cancellation tasks were
added directly to `self._cancellation_tasks` using
`asyncio.create_task()`:
```python
self._cancellation_tasks.append(asyncio.create_task(self._kill_running_command(command)))
```
This caused issues when cancellation tasks were created from multiple
event loops, leading to loop mismatch errors during executor shutdown.
*Solution*
This PR fixes the issue by introducing a dedicated internal event loop
for managing cancellation tasks.
Cancellation tasks are now scheduled in a fixed event loop using
`asyncio.run_coroutine_threadsafe()`:
```python
future: ConcurrentFuture[None] = asyncio.run_coroutine_threadsafe(
self._kill_running_command(command), self._loop
)
self._cancellation_futures.append(future)
```
*Additional Changes*
- Added detailed logging for easier debugging.
- Ensured clean shutdown of the internal event loop and associated
thread.
*Note*
This change ensures that all cancellation tasks are handled consistently
in a single loop, preventing cross-loop conflicts and improving executor
stability in multi-threaded environments.

* Replace on_messages and on_messages_stream with run and run_stream to
unify interface documentation with teams
* Remove magentic-one-cli from homepage as it has not been maintained
and improved for a while.
Finishing up the work on workbench.
```python
import asyncio
from autogen_agentchat.agents import AssistantAgent
from autogen_agentchat.ui import Console
from autogen_ext.models.openai import OpenAIChatCompletionClient
from autogen_ext.tools.mcp import StdioServerParams, McpWorkbench
async def main() -> None:
params = StdioServerParams(
command="uvx",
args=["mcp-server-fetch"],
read_timeout_seconds=60,
)
# You can also use `start()` and `stop()` to manage the session.
async with McpWorkbench(server_params=params) as workbench:
model_client = OpenAIChatCompletionClient(model="gpt-4.1-nano")
assistant = AssistantAgent(
name="Assistant",
model_client=model_client,
workbench=workbench,
reflect_on_tool_use=True,
)
await Console(assistant.run_stream(task="Go to https://github.com/microsoft/autogen and tell me what you see."))
asyncio.run(main())
```
## Why are these changes needed?
> The pytest tests test_local_executor_with_custom_venv and
test_local_executor_with_custom_venv_in_local_relative_path located in
packages/autogen-ext/tests/code_executors/test_commandline_code_executor.py
fail when run on macOS (aarch64) using a Python interpreter managed by
uv (following the project's recommended development setup).
>
> The failure occurs during the creation of a nested virtual environment
using Python's standard venv.EnvBuilder. Specifically, the attempt to
run ensurepip inside the newly created venv fails immediately with a
SIGABRT signal. The root cause appears to be a dynamic library loading
error (dyld error) where the Python executable inside the newly created
venv cannot find its required libpythonX.Y.dylib shared library.
So, when MacOS + uv case, skipping that test.
And, adding uv-venv case
