From fdd73f149c618f88140bfeb9f8e17e0148ebb1ed Mon Sep 17 00:00:00 2001 From: Ariel Frischer Date: Wed, 12 Mar 2025 11:16:54 -0700 Subject: [PATCH] feat(agent_utils.py): add support for sonnet_35_state_modifier for Claude 3.5 models to enhance token management chore(anthropic_message_utils.py): remove debug print statements to clean up code and improve readability chore(anthropic_token_limiter.py): remove debug print statements and replace with logging for better monitoring test(test_anthropic_token_limiter.py): update tests to verify correct behavior of sonnet_35_state_modifier without patching internal logic --- ra_aid/agent_utils.py | 5 +- ra_aid/anthropic_message_utils.py | 74 -------------------- ra_aid/anthropic_token_limiter.py | 40 +---------- tests/ra_aid/test_anthropic_token_limiter.py | 47 +++++++------ 4 files changed, 31 insertions(+), 135 deletions(-) diff --git a/ra_aid/agent_utils.py b/ra_aid/agent_utils.py index d0f26cb..f87acab 100644 --- a/ra_aid/agent_utils.py +++ b/ra_aid/agent_utils.py @@ -47,7 +47,7 @@ from ra_aid.logging_config import get_logger from ra_aid.models_params import DEFAULT_TOKEN_LIMIT from ra_aid.tools.handle_user_defined_test_cmd_execution import execute_test_command from ra_aid.database.repositories.config_repository import get_config_repository -from ra_aid.anthropic_token_limiter import state_modifier, get_model_token_limit +from ra_aid.anthropic_token_limiter import sonnet_35_state_modifier, state_modifier, get_model_token_limit console = Console() @@ -95,6 +95,9 @@ def build_agent_kwargs( ): def wrapped_state_modifier(state: AgentState) -> list[BaseMessage]: + if any(pattern in model.model for pattern in ["claude-3.5", "claude3.5", "claude-3-5"]): + return sonnet_35_state_modifier(state, max_input_tokens=max_input_tokens) + return state_modifier(state, model, max_input_tokens=max_input_tokens) agent_kwargs["state_modifier"] = wrapped_state_modifier diff --git a/ra_aid/anthropic_message_utils.py b/ra_aid/anthropic_message_utils.py index e71d0ed..79f271e 100644 --- a/ra_aid/anthropic_message_utils.py +++ b/ra_aid/anthropic_message_utils.py @@ -124,23 +124,6 @@ def anthropic_trim_messages( kept_messages = messages[:num_messages_to_keep] remaining_msgs = messages[num_messages_to_keep:] - # Debug: Print message types for all messages - print("\nDEBUG - All messages:") - for i, msg in enumerate(messages): - msg_type = type(msg).__name__ - tool_use = ( - "tool_use" - if isinstance(msg, AIMessage) - and hasattr(msg, "additional_kwargs") - and msg.additional_kwargs.get("tool_calls") - else "" - ) - tool_result = ( - f"tool_call_id: {msg.tool_call_id}" - if isinstance(msg, ToolMessage) and hasattr(msg, "tool_call_id") - else "" - ) - print(f" [{i}] {msg_type} {tool_use} {tool_result}") # For Anthropic, we need to maintain the conversation structure where: # 1.
