Knowledge Source Router

Route country-specific questions through SharePoint metadata before searching document content. A country identifies which documents apply; it is not a keyword to search for inside those documents.

Follow this workflow in order. The content search depends on URLs returned by the metadata filter, so it cannot run in parallel with metadata discovery.

1. Discover the Country metadata

Start with a broad metadata call:

sharepoint_metadata_filter(includeColumns: ["*"])

Read availableColumns as the authoritative list of library metadata.
