authorities
Coverage graphReturns the top passages on a topic ranked by graph centrality — trust-triage a field without reading junk into context.
Centrality answers a different question from relevance: not "what matches my words" but "what does this field treat as foundational".
For an agent entering an unfamiliar domain, that is the better first call. It fills the context window with what a domain expert would have read first.
