strands.agent.conversation_manager.null_conversation_manager

Null implementation of conversation management.

NullConversationManager

class NullConversationManager(ConversationManager)

Defined in: src/strands/agent/conversation_manager/null_conversation_manager.py:11

A no-op conversation manager that does not modify the conversation history.

Useful for:

• Testing scenarios where conversation management should be disabled
• Cases where conversation history is managed externally
• Situations where the full conversation history should be preserved

apply_management

def apply_management(agent: "Agent", **kwargs: Any) -> None

Defined in: src/strands/agent/conversation_manager/null_conversation_manager.py:21

Does nothing to the conversation history.

Arguments:

• agent - The agent whose conversation history will remain unmodified.
• **kwargs - Additional keyword arguments for future extensibility.

reduce_context

def reduce_context(agent: "Agent",
                   e: Exception | None = None,
                   **kwargs: Any) -> None

Defined in: src/strands/agent/conversation_manager/null_conversation_manager.py:30

Does not reduce context.

When called reactively (e is not None), re-raises the overflow exception since this manager cannot reduce context. When called proactively (e is None), returns silently.

Arguments:

• agent - The agent whose conversation history will remain unmodified.
• e - The exception that triggered the context reduction, if any.
• **kwargs - Additional keyword arguments for future extensibility.

Raises:

• e - If provided (reactive overflow).
