Unknown types return `None`. + +**Response conversion:** The SDK uses OpenAI Responses API format internally. The exporter converts to Chat Completions format (`{role, content}` messages) so the Respan UI renders clean System/User/Assistant/Tool messages. + +**Token extraction:** Handles both Responses API keys (`input_tokens`/`output_tokens`) and Chat Completions keys (`prompt_tokens`/`completion_tokens`). Uses `is not None` checks to preserve `0` as valid. + +**Thread safety:** `RespanTraceProcessor` uses `BatchTraceProcessor` with `queue.Queue`. `LocalSpanCollector` uses `threading.Lock`. Both are safe for concurrent agent runs. + +## Links + +- Docs: https://docs.respan.ai/integrations/tracing/openai-agents-sdk +- Complex example (12 scenarios): https://docs.respan.ai/integrations/tracing/openai-agents-sdk-complex-example +- Example projects: https://github.com/respanai/respan-example-projects/tree/main/python/tracing/openai-agents-sdk +- PyPI: https://pypi.org/project/respan-exporter-openai-agents/ diff --git a/python-sdks/respan-exporter-openai-agents/src/respan_exporter_openai_agents/respan_openai_agents_exporter.py b/python-sdks/respan-exporter-openai-agents/src/respan_exporter_openai_agents/respan_openai_agents_exporter.py index b55886bd..fe6802d0 100644 --- a/python-sdks/respan-exporter-openai-agents/src/respan_exporter_openai_agents/respan_openai_agents_exporter.py +++ b/python-sdks/respan-exporter-openai-agents/src/respan_exporter_openai_agents/respan_openai_agents_exporter.py @@ -2,6 +2,7 @@ import random import threading import time +import warnings from typing import Any, Dict, List, Optional, Union import httpx @@ -28,59 +29,290 @@ LOG_TYPE_TOOL, ) from respan_sdk.respan_types.param_types import RespanTextLogParams +from respan_sdk.utils.serialization import safe_attr, safe_serialize logger = logging.getLogger(__name__) +warnings.filterwarnings( + "ignore", + message="Pydantic serializer warnings", + category=UserWarning, +) + +# --------------------------------------------------------------------------- +# Constants — Responses API item types and Chat Completions roles +# --------------------------------------------------------------------------- + +ITEM_TYPE_MESSAGE = "message" +ITEM_TYPE_FUNCTION_CALL = "function_call" +ITEM_TYPE_FUNCTION_CALL_OUTPUT = "function_call_output" + +CONTENT_TYPE_OUTPUT_TEXT = "output_text" +CONTENT_TYPE_INPUT_TEXT = "input_text" +CONTENT_TYPE_TEXT = "text" + +ROLE_SYSTEM = "system" +ROLE_USER = "user" +ROLE_ASSISTANT = "assistant" +ROLE_TOOL = "tool" + +TOOL_CALL_TYPE_FUNCTION = "function" + +METADATA_KEY_FROM_AGENT = "from_agent" +METADATA_KEY_TO_AGENT = "to_agent" +METADATA_KEY_OUTPUT_TYPE = "output_type" +METADATA_KEY_AGENT_NAME = "agent_name" + +GUARDRAIL_TRIGGERED_MSG = "guardrail triggered" + +# Responses API item field names (used with safe_attr() to extract values) +FIELD_NAME = "name" +FIELD_ARGUMENTS = "arguments" +FIELD_CALL_ID = "call_id" +FIELD_OUTPUT = "output" + +# Usage dict keys — Responses API uses input_tokens/output_tokens, +# Chat Completions API uses prompt_tokens/completion_tokens +USAGE_KEY_INPUT_TOKENS = "input_tokens" +USAGE_KEY_OUTPUT_TOKENS = "output_tokens" +USAGE_KEY_PROMPT_TOKENS = "prompt_tokens" +USAGE_KEY_COMPLETION_TOKENS = "completion_tokens" +USAGE_KEY_INPUT_DETAILS = "input_tokens_details" +USAGE_KEY_CACHED_TOKENS = "cached_tokens" + +_CUSTOM_SPAN_PASSTHROUGH_KEYS = ("input", "output", "model", "prompt_tokens", "completion_tokens") + + +# --------------------------------------------------------------------------- +# Responses API → Chat Completions format converters +# +# The backend renders input/output using Chat Completions message format +# (role + content).
