The preview's content lives in the desktop renderer (a sandboxed ```` for URL tabs), so this tool round-trips through the gateway's blocking-prompt bridge — the same one ``read_terminal`` uses: tui_gateway emits ``preview.read.request``, the renderer serializes the active preview tab and answers with ``preview.read.respond``. This module is just schema + a thin dispatcher over the platform-injected callback. Lives in the ``desktop_ui`` toolset, which the GUI gateway enables only for desktop-sourced sessions.

Call with no arguments for the first window of the active tab's content. Returns JSON {kind, url, title, text, start, end, total_chars, note?}: a URL (Browser) tab's text is the rendered page's visible text — page through longer pages with `start`/`count` (character offsets, capped per read); a file tab answers identity only (read the file with read_file); an artifact tab points back at the conversation.
