Structured search data via 130+ engines — use INSTEAD OF web_search when you need: exact citations (google_scholar), local business details (google_maps), flight prices (google_flights), hotel rates (google_hotels), shopping prices (google_shopping_light), job listings (google_jobs), or any task where web_search gives approximate/unstructured results. Returns machine-readable JSON. Default engine: google_light.
Test whether agents can discover and use your tool — not whether agents are capable. The subject under test is the interface. A bad score means fix the docs/tool, not the agent.
