Actions for env.step

The actions parameter passed to the OASIS environment’s step method should be a dictionary that specifies what each agent should do at a given timestep, as shown below: 
dict[SocialAgent, Union[List[Union[ManualAction, LLMAction]],Union[ManualAction, LLMAction]]]
  • The key is a SocialAgent.
  • The value is either:
    • A single predefined ManualAction or an LLM-generated LLMAction, or
    • A list of ManualAction or LLMAction instances, allowing the same agent to perform multiple actions within one timestep.

​
LLMAction

You can use LLMAction() to indicate that an agent should perform actions based on the output of an LLM. These actions can include both social actions and external tools, as defined during initialization. An example where all agents use LLMAction() to perform actions: 
from oasis import LLMAction

all_llm_actions = {
    agent: LLMAction()
    for _, agent in env.agent_graph.get_agents()
}

await env.step(all_llm_actions)

​
ManualAction

You can use ManualAction() to indicate that an agent should perform actions based on the predefined ActionType and corresponding arguments.
  • The data structure of ManualAction:
@dataclass
class ManualAction:
    r"""Some manual predefined social platform actions that need to be
    executed by certain agents.

    Args:
        agent_id: The ID of the agent that will perform the action.
        action: The action to perform.
        args: The arguments to pass to the action. For details of each args in
            each action, please refer to
            `https://github.com/camel-ai/oasis/blob/main/oasis/social_agent/agent_action.py`.
    """
    action_type: ActionType
    action_args: Dict[str, Any]

    def init(self, action_type, action_args):
        self.action_type = action_type
        self.action_args = action_args
  • A example of using ManualAction():
from oasis import ActionType

actions = {}

manual_action = ManualAction(
    action=ActionType.CREATE_POST,
    args={"content": "Hello, OASIS world!"}
)

actions[env.agent_graph.get_agents(0)] = manual_action

await env.step(actions)
For more details about the ActionType and corresponding arguments, please refer to the ActionType section.
