A one-shot graph ranking diffuses over the whole neighbourhood; a question whose answer sits two hops away is better served by following the edges. The graph_search tool gives an agent search_entities, get_relationships and read_entity_pages over its graph sources. On a multi-hop corpus where the bridging entity is never named, answers went from 0/10 with classic vector retrieval to 10/10 with the tool, end to end through /stream. The tool has no setting of its own. It is offered exactly where the agent can already search: agentic and research agents always, a classic agent only for sources exposed as a search tool. A graph source left at prefetch is used for ranking only. Tests now pin GRAPHRAG_ENABLED to its shipped default, as CI has: with a dev .env enabling it, every agent test's graph check read the developer's real database and left a pool to it behind.
