Usage of AgentExecutor in prebuilt WorkflowBuilders such as MagenticOneBuilder & GroupChatBuilder

[JensDeClercq1]

Currently the usage of AgentExecutors as participants in MagenticOne & GroupChat will result in no invoking of the AgentExecutors. I was wondering if this implementation / fix is planned for the near future.
If not, which approach should I take for agent-level or even workflow-level persistent chat history?
Currently I'm using AgentExecutors since they can be used for agent level chat history in workflows such as SequentialBuilder or HandoffBuilder.

@TaoChenOSU will this be supported after the orchestration refactoring goes into main?

Actually, @JensDeClercq1, as I re-read this, I have some thoughts to share. The approach you're trying is more complex than needed - the builders handle the wrapping for you. The idea is to pass agents directly, not AgentExecutor instances:

from agent_framework import GroupChatBuilder, FileCheckpointStorage

storage = FileCheckpointStorage("./checkpoints")

workflow = (
    GroupChatBuilder()
    .set_manager(manager_agent)
    .participants(researcher=researcher_agent, writer=writer_agent)
    .with_checkpointing(storage)
    .build()
)

The builders automatically wrap AgentProtocol instances in AgentExecutor internally. When you pass an AgentExecutor directly, it gets treated as a generic custom Executor, which uses different internal message types and won't be invoked as expected.

For persistent chat history:

Use .with_checkpointing(storage) - this persists workflow state across runs. Storage options include:

• MemoryCheckpointStorage - in-memory (for testing)
• FileCheckpointStorage - file-based persistence

To resume from a checkpoint:

events = await workflow.run("continue the conversation", checkpoint_id="previous-run-id")

Let me know if you hit any issues with this approach.

Many thanks, for some reason I thought sending a prompt with checkpoint_id didn't work, my apologies. Will try out this approach, greatly appreciate the response!!
