Sets them on LLMInvocation.input_messages/output_messages +# 5. Evaluators receive full message objects → evaluations work! +# +# Benefits: +# - Single library (Traceloop SDK only, no dual instrumentation) +# - No circular import issues (different initialization path) +# - Simpler architecture (one instrumentation instead of two) +# - Better performance (one callback instead of two) +# +# Note: langchain-core must be installed for message reconstruction to work, +# but LangChain instrumentation is NOT needed. +print("✓ Message reconstruction enabled in translator (no LangChain instrumentation needed)") + +# --------------------------------------------------------------------------- +# Sample data utilities +# --------------------------------------------------------------------------- + +DESTINATIONS = { + "paris": { + "country": "France", + "currency": "EUR", + "airport": "CDG", + "highlights": [ + "Eiffel Tower at sunset", + "Seine dinner cruise", + "Day trip to Versailles", + ], + }, + "tokyo": { + "country": "Japan", + "currency": "JPY", + "airport": "HND", + "highlights": [ + "Tsukiji market food tour", + "Ghibli Museum visit", + "Day trip to Hakone hot springs", + ], + }, + "rome": { + "country": "Italy", + "currency": "EUR", + "airport": "FCO", + "highlights": [ + "Colosseum underground tour", + "Private pasta masterclass", + "Sunset walk through Trastevere", + ], + }, +} + + +def _pick_destination(user_request: str) -> str: + lowered = user_request.lower() + for name in DESTINATIONS: + if name in lowered: + return name.title() + return "Paris" + + +def _pick_origin(user_request: str) -> str: + lowered = user_request.lower() + for city in ["seattle", "new york", "san francisco", "london"]: + if city in lowered: + return city.title() + return "Seattle" + + +def _compute_dates() -> tuple[str, str]: + start = datetime.now() + timedelta(days=30) + end = start + timedelta(days=7) + return start.strftime("%Y-%m-%d"), end.strftime("%Y-%m-%d") + + +# --------------------------------------------------------------------------- +# Tools exposed to agents +# --------------------------------------------------------------------------- + + +@tool +def mock_search_flights(origin: str, destination: str, departure: str) -> str: + """Return mock flight options for a given origin/destination pair.""" + random.seed(hash((origin, destination, departure)) % (2**32)) + airline = random.choice(["SkyLine", "AeroJet", "CloudNine"]) + fare = random.randint(700, 1250) + return ( + f"Top choice: {airline} non-stop service {origin}->{destination}, " + f"depart {departure} 09:15, arrive {departure} 17:05.
