ProgrammableAgentRequirement

class ProgrammableAgentRequirement(Enum):

Requirements for programmable agent state.

Defines the possible requirements that can be used to repair the state of a programmable agent.

Attributes: LAST_MESSAGE_NOT_USER (str): Requires that the last message in the conversation was not from the user.

​
ProgrammedAgentInstructionResult

class ProgrammedAgentInstructionResult(BaseModel):

Result of a programmable agent instruction execution.

Contains the messages exchanged during execution and the computed value. The value type is specified by the generic type parameter T.

Attributes: user_message (BaseMessage): The message sent by the user. agent_message (BaseMessage): The message sent by the agent. value (T): The computed result value of type T.

​
AbstractProgrammableAgent

class AbstractProgrammableAgent(ABC):

Abstract class for a programmable agent.

A programmable agent is an agent that can be programmed to perform a specific function or task. This class defines the interface for a programmable agent.

These methods should be implemented in order to ensure the agent supports the necessary guarantees to enable a programming interface while maintaining compatibility in a multi-agent system.

A programmable agent is responsible for providing and maintaining a programming interface for its functionality.

​
run_atomic

def run_atomic(
    self,
    callback: Callable[[], ProgrammedAgentInstructionResult[T]]
):

Run an atomic operation on the agent.

An atomic operation is an operation that is guaranteed to be executed without interruption by any other operation.

Parameters:

  • callback (Callable[[], ProgrammedAgentInstructionResult[T]]): The operation to execute atomically.

Returns:

ProgrammedAgentInstructionResult[T]: The result of the operation.

​
repair_state

def repair_state(self, requirement: ProgrammableAgentRequirement):

Repair the state of the agent.

Agents may have other non-atomic interfaces, such as a user interface, or chat between other agents. This method should restore the agent to a state where it can perform operations according to the specified requirement.

Parameters:

  • requirement (ProgrammableAgentRequirement): The requirement to repair the state for.

​
programmable_capability

def programmable_capability(func: Callable[..., ProgrammedAgentInstructionResult[T]]):

Decorator for programmable agent capabilities.

This decorator ensures that the decorated method is executed atomically and maintains the agent’s state guarantees.

Parameters:

  • func (Callable[…, ProgrammedAgentInstructionResult[T]]): The method to decorate.

Returns:

Callable[…, ProgrammedAgentInstructionResult[T]]: The decorated method that ensures atomic execution.

​
ProgrammableChatAgent

class ProgrammableChatAgent(ChatAgent, AbstractProgrammableAgent):

A chat agent that can be programmed to perform specific tasks.

Provides a default implementation of atomic execution using threading locks and basic state tracking for message roles. Implementing classes need to provide specific repair logic for their use cases.

Attributes: _operation_lock (threading.Lock): Lock for ensuring atomic operations. _last_message_role (Optional[str]): Role of the last message in the conversation.

​
init

def __init__(self, **kwargs: Any):

Initialize the ProgrammableChatAgent.

​
run_atomic

def run_atomic(
    self,
    callback: Callable[[], ProgrammedAgentInstructionResult[T]]
):

Run an atomic operation on the agent.

Ensures thread-safe execution of the callback function by using a lock.

Parameters:

  • callback (Callable[[], ProgrammedAgentInstructionResult[T]]): The operation to execute atomically.

Returns:

ProgrammedAgentInstructionResult[T]: The result of the operation.

​
repair_state

def repair_state(self, requirement: ProgrammableAgentRequirement):

Repair the state of the agent.

Implements basic state repair for message role requirements.

Parameters:

  • requirement (ProgrammableAgentRequirement): The requirement to repair the state for.
