# Preview available data for context document generation

`GET /context-documents/data-summary`

Show what data is available before generating a context document.

Returns per-source breakdowns with counts, date ranges, and sample
titles so callers (humans or agents) can understand what's in the
system and decide what to include.

This is the "menu" — show them what we have, let them pick.
