Team to support a list of messages as input to a task

[ekzhu]

Currently a team only support a single message for task.

result = await team.run(task="...")

It should support a list of messages, to prepopulate the context of the agents.

result = await team.run(task=[TextMessage(...), TextMessage(...)])

This allows passing a previous conversation history from another team.

This is also useful for nested chats to prepopulate the team participants with messages before generating a response.

Interesting idea ..
This sounds like what team.load_state() does in #4100.
Also, in the above example

result = await team.run(task=[TextMessage(...), TextMessage(...)])

Does this populate the context for ALL agents or some agents etc?
In PR #4436 ,team_state has an agent_states field that is a dict and maps to each agent. This way specific list of messages are mapped to the actual agent from which they were serialized (or created for) in team.load_state()

from autogen_agentchat.state import BaseTeamState

# convert team state to dict (save to file if needed)
team_state_dict = vars(team_state)
print(team_state_dict)      

# convert back to team state object
team_state = BaseTeamState(**vars(team_state)) 

# load team state
await agent_team.load_state(team_state)
stream = agent_team.run_stream(task="What was the last line of the poem you wrote?")
await Console(stream)

I think the list of messages as task is to allow better integration with applications. E.g., in a scenario where users might type multiple messages before the application triggering the team run, and nest chats.

The load and save states are designed for persistence and editing of agent states.

They both serve different purposes.
