Workforce

class Workforce(BaseNode):

A system where multiple worker nodes (agents) cooperate together to solve tasks. It can assign tasks to worker nodes and also take strategies such as create new worker, decompose tasks, etc. to handle situations when the task fails. The workforce uses three specialized ChatAgents internally:

Coordinator Agent: Assigns tasks to workers based on their capabilities
Task Planner Agent: Decomposes complex tasks and composes results
Dynamic Workers: Created at runtime when tasks fail repeatedly

Parameters:

description (str): Description of the workforce.
children (Optional[List[BaseNode]], optional): List of child nodes under this node. Each child node can be a worker node or another workforce node. (default: :obj:None)
coordinator_agent (Optional[ChatAgent], optional): A custom coordinator agent instance for task assignment and worker creation. If provided, the workforce will create a new agent using this agent’s model configuration but with the required system message and functionality. If None, a default agent will be created using DEFAULT model settings. (default: :obj:None)
task_agent (Optional[ChatAgent], optional): A custom task planning agent instance for task decomposition and composition. If provided, the workforce will create a new agent using this agent’s model configuration but with the required system message. If None, a default agent will be created using DEFAULT model settings. (default: :obj:None)
new_worker_agent (Optional[ChatAgent], optional): A template agent for workers created dynamically at runtime when existing workers cannot handle failed tasks. If None, workers will be created with default settings including SearchToolkit, CodeExecutionToolkit, and ThinkingToolkit. (default: :obj:None) default_model (Optional[Union[BaseModelBackend, ModelManager]], optional): Model backend or manager to use when creating default coordinator, task, or dynamic worker agents. If None, agents will be created using ModelPlatformType.DEFAULT and ModelType.DEFAULT settings. (default: :obj:None)
graceful_shutdown_timeout (float, optional): The timeout in seconds for graceful shutdown when a task fails 3 times. During this period, the workforce remains active for debugging. Set to 0 for immediate shutdown. (default: :obj:15.0)
task_timeout_seconds (Optional[float], optional): The timeout in seconds for waiting for tasks to be returned by workers. If None, uses the global TASK_TIMEOUT_SECONDS value (600.0 seconds). Increase this value for tasks that require more processing time. (default: :obj:None)
share_memory (bool, optional): Whether to enable shared memory across SingleAgentWorker instances in the workforce. When enabled, all SingleAgentWorker instances, coordinator agent, and task planning agent will share their complete conversation history and function-calling trajectory, providing better context for task handoffs and continuity. Note: Currently only supports SingleAgentWorker instances; RolePlayingWorker and nested Workforce instances do not participate in memory sharing. (default: :obj:False)
use_structured_output_handler (bool, optional): Whether to use the structured output handler instead of native structured output. When enabled, the workforce will use prompts with structured output instructions and regex extraction to parse responses. This ensures compatibility with agents that don’t reliably support native structured output. When disabled, the workforce uses the native response_format parameter. (default: :obj:True)
callbacks (Optional[List[WorkforceCallback]], optional): A list of callback handlers to observe and record workforce lifecycle events and metrics (e.g., task creation/assignment/start/completion/ failure, worker creation/deletion, all-tasks-completed). All items must be instances of :class:WorkforceCallback, otherwise
a: class:ValueError is raised. If none of the provided callbacks implement :class:WorkforceMetrics, a built-in :class:WorkforceLogger (implements both callback and metrics) is added automatically. If at least one provided callback
implements: class:WorkforceMetrics, no default logger is added. (default: :obj:None)
mode (WorkforceMode, optional): The execution mode for task processing. AUTO_DECOMPOSE mode uses intelligent recovery strategies (decompose, replan, etc.) when tasks fail. PIPELINE mode uses simple retry logic and allows failed tasks to continue the workflow, passing error information to dependent tasks. (default: :obj:WorkforceMode.AUTO_DECOMPOSE)
failure_handling_config (Optional[Union[FailureHandlingConfig, Dict]]): Configuration for customizing failure handling behavior. Can be a FailureHandlingConfig instance or a dict with the same fields. Allows fine-grained control over which recovery strategies are enabled, maximum retry attempts, and whether to halt on max retries. The enabled_strategies field accepts both enum values and string lists like ["retry", "replan"]. If None, uses default configuration with all strategies enabled. (default: :obj:None)

Note: When custom coordinator_agent or task_agent are provided, the workforce will preserve the user’s system message and append the required workforce coordination or task planning instructions to it. This ensures both the user’s intent is preserved and proper workforce functionality is maintained. All other agent configurations (model, memory, tools, etc.) will also be preserved.

pause

def pause(self):

Pause the workforce execution. If the internal event-loop is already running we schedule the asynchronous pause coroutine onto it. When the loop has not yet been created (e.g. the caller presses the hot-key immediately after workforce start-up) we fall back to a synchronous state change so that no tasks will be scheduled until the loop is ready.

resume

def resume(self):

Resume execution after a manual pause.

stop_gracefully

def stop_gracefully(self):

Request workforce to finish current in-flight work then halt. Works both when the internal event-loop is alive and when it has not yet been started. In the latter case we simply mark the stop flag so that the loop (when it eventually starts) will exit immediately after initialisation.

def stop_immediately(self):

Force-stop without waiting for current tasks to finish. Note: Child nodes will receive stop signals but may still be cleaning up when this method returns.

skip_gracefully

This method clears the current pending subtasks and moves to the next main task in the queue if available. Works both when the internal event-loop is alive and when it has not yet been started.

    self,
    name: str = 'CAMEL-Workforce',
    description: str = 'A workforce system using the CAMEL AI framework for multi-agent collaboration.',
    dependencies: Optional[List[str]] = None,
    host: str = 'localhost',
    port: int = 8001
):

Expose this Workforce as an MCP server. Parameters:

name (str): Name of the MCP server. (default: :obj:CAMEL-Workforce)
description (str): Description of the workforce. If None, a generic description is used. (default: :obj:A workforce system using the CAMEL AI framework for multi-agent collaboration.)
dependencies (Optional[List[str]]): Additional dependencies for the MCP server. (default: :obj:None)
host (str): Host to bind to for HTTP transport. (default: :obj:localhost)
port (int): Port to bind to for HTTP transport. (default: :obj:8001)

Returns: FastMCP: An MCP server instance that can be run.
