From 46235919e46ea80d509c065b43163a5c79388794 Mon Sep 17 00:00:00 2001 From: nicklongmore86 Date: Sat, 24 Oct 2026 15:48:56 +0000 Subject: [PATCH 1/7] Add the read_document tool and send PDF attachments as text and page images read_document reads PDFs and images inside the granted folders through the sandboxed DocumentWorkerHost: text page by page with a continuation hint, drawn/scanned pages and photos as ToolResult.images, page ranges, `start`, zoomed regions and GPS only with include_location (audited as includeLocation/locationRead). Same guard and verified open as read_file; read-only and audited. HEIC/AVIF/Office answer "not supported yet"; reader refusals and worker failures become clean tool errors. Adds ToolImage / ToolResult.images (shared contract with feat/provider-images); defineTool passes images through and merges RunResult.audit into the entry. read_file's binary refusal points PDFs and images to read_document. PDF attachments are converted when sending (fenced, untrusted), with drawn pages as image blocks on the Claude API and a note elsewhere; results are cached per attachment id and PDF chips are no longer greyed. One host per app, disposed on quit.

cachedPdfReading keeps at most 16 views and 64 MB in all (least recently used out first); a view larger than the cap is used once and not kept. - A connection known not to see images reads its PDFs as text only (no page renders). A cached text-only view is read again with its pages when a later send can use them. - toModelConversation reads image and PDF attachments newest first, as withImageBudget orders them, and asks each PDF for no more page images than the request's budget (20) has left, 8 at most; older PDFs get text.
