Indexes long documents as a reasoning-based hierarchical tree so agents retrieve by navigating structure instead of embedding similarity.

Skills

Tree Index Generation
Builds a hierarchical table-of-contents index over long documents that mirrors their actual section structure.
Reasoning Retrieval
Navigates the document tree by reasoning about which sections answer a query, with no embedding database required.
Citation Tracing
Returns the exact node and page a retrieved passage came from so answers stay traceable to the source document.
