Agent pipeline

BasePipelineElement

Bases: ABC

Base class for agent pipeline elements.

Subclasses must implement the query method.

query abstractmethod

query(
    query: str,
    runtime: FunctionsRuntime,
    env: Env = EmptyEnv(),
    messages: Sequence[ChatMessage] = [],
    extra_args: dict = {},
) -> tuple[
    str, FunctionsRuntime, Env, Sequence[ChatMessage], dict
]

Executes the element of the pipeline on the given query, runtime, environment, and messages.

Must be implemented by the subclass.

Parameters:

• query (str) –

  the query to execute.

• runtime (FunctionsRuntime) –

  the runtime that can be used by the agent to execute tools.

• env (Env, default: EmptyEnv() ) –

  the environment on which the agent is operating.

• messages (Sequence[ChatMessage], default: [] ) –

  the list of chat messages exchanged between the agent, the user, and the tools.

• extra_args (dict, default: {} ) –

  extra arguments that can be used by the agent to execute the query and passed around among different pipeline elements.

PipelineConfig

Bases: BaseModel

llm instance-attribute

llm: str

Which LLM to use. One of the models in ModelsEnum.

defense instance-attribute

defense: str | None

Which defense to use. One of the defenses in DEFENSES.

system_message_name instance-attribute

system_message_name: str | None

The name of the system message to use. If not provided, the default system message will be used.

system_message instance-attribute

system_message: str | None

The system message to use. If not provided, the default system message will be used. If provided, it will override system_message_name.

InitQuery

Bases: BasePipelineElement

Initializes the pipeline execution with the user query, by adding a ChatUserMessage to the messages list.

GroundTruthPipeline

GroundTruthPipeline(
    task: BaseUserTask | BaseInjectionTask | None,
)

Bases: BasePipelineElement

Pipeline that executes a task's ground_truth.

It is used to identify which injection placeholders are seen by the agent during the task execution.

Source code in src/agentdojo/agent_pipeline/ground_truth_pipeline.py

def __init__(self, task: BaseUserTask | BaseInjectionTask | None) -> None:
    self._task = task

SystemMessage

SystemMessage(system_message: str)

Bases: BasePipelineElement

Adds a system message to the messages list (as a ChatSystemMessage).

Parameters:

• system_message (str) –

  the content of the system message.

Source code in src/agentdojo/agent_pipeline/basic_elements.py

def __init__(self, system_message: str) -> None:
    self.system_message = system_message

Function execution elements

ToolsExecutor

ToolsExecutor(
    tool_output_formatter: Callable[
        [FunctionReturnType], str
    ] = tool_result_to_str
)

Bases: BasePipelineElement

Executes the tool calls in the last messages for which tool execution is required.

Parameters:

• tool_output_formatter (Callable[[FunctionReturnType], str], default: tool_result_to_str ) –

  a function that converts a tool's output into plain text to be fed to the model. It should take as argument the tool output, and convert it into a string. The default converter converts the output to structured YAML.

Source code in src/agentdojo/agent_pipeline/tool_execution.py

def __init__(self, tool_output_formatter: Callable[[FunctionReturnType], str] = tool_result_to_str) -> None:
    self.output_formatter = tool_output_formatter

ToolsExecutionLoop

ToolsExecutionLoop(
    elements: Sequence[BasePipelineElement],
    max_iters: int = 15,
)

Bases: BasePipelineElement

Executes in loop a sequence of pipeline elements related to tool execution until the LLM does not return any tool calls.

Parameters:

• elements (Sequence[BasePipelineElement]) –

  a sequence of pipeline elements to be executed in loop. One of them should be an LLM, and one of them should be a ToolsExecutor (or something that behaves similarly by executing function calls). You can find an example usage of this class here.

• max_iters (int, default: 15 ) –

  maximum number of iterations to execute the pipeline elements in loop.

Source code in src/agentdojo/agent_pipeline/tool_execution.py

def __init__(self, elements: Sequence[BasePipelineElement], max_iters: int = 15) -> None:
    self.elements = elements
    self.max_iters = max_iters

tool_result_to_str

tool_result_to_str(
    tool_result: FunctionReturnType,
    dump_fn: Callable[
        [dict | list[dict]], str
    ] = yaml.safe_dump,
) -> str

Basic tool output formatter with YAML dump by default. Could work with json.dumps as dump_fn.

Source code in src/agentdojo/agent_pipeline/tool_execution.py

def tool_result_to_str(
    tool_result: FunctionReturnType, dump_fn: Callable[[dict | list[dict]], str] = yaml.safe_dump
) -> str:
    """Basic tool output formatter with YAML dump by default. Could work with `json.dumps` as
    `dump_fn`."""
    if isinstance(tool_result, BaseModel):
        return dump_fn(tool_result.model_dump()).strip()

    if isinstance(tool_result, list):
        res_items = []
        for item in tool_result:
            if type(item) in [str, int]:
                res_items += [str(item)]
            elif isinstance(item, BaseModel):
                res_items += [item.model_dump()]
            else:
                raise TypeError("Not valid type for item tool result: " + str(type(item)))

        # If type checking passes, this is guaranteed to be a list of BaseModel
        return dump_fn(res_items).strip()

    return str(tool_result)

Exceptions

AbortAgentError

AbortAgentError(
    message: str,
    messages: list[ChatMessage],

Checking tools can raise this exception to abort the execution of the agent pipeline (e.g. when a prompt injection is detected).

Source code in src/agentdojo/agent_pipeline/errors.py

def __init__(
    self,
    message: str,
    messages: list[ChatMessage],
    task_environment: TaskEnvironment,
