AI agents call lookup_trip_details to retrieve information from Sana without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The 'lookup' verb strongly implies a read-only query operation that retrieves existing trip details. No side effects, modifications, deletions, or external operations are suggested by the name. Given the sibling tools include search and query operations (search_trips, search_items, evaluate_*), this tool likely follows the same read pattern.
From the tool's definition Tool name 'lookup_trip_details' indicates data retrieval. The empty description prevents full certainty, but the naming convention and context within a trip management system suggest it queries trip information without modification.
