From 7bd9e97509aa53ec8ae40f378ed1106770a479bd Mon Sep 17 00:00:00 2001 From: Eric Lee Date: Tue, 22 Sep 2026 21:11:55 -0700 Subject: [PATCH 1/3] feat(web): attach files of any type from the composer, beside images MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The composer's Add menu offered an image picker only. It now has a File row too, for every model: a text file is inlined into the prompt, and a PDF, an archive or a spreadsheet is saved where the agent's Read tool can open it. A drop or a paste sorts its files the same way — images the image way, everything else as a file. The mechanism is the image one, generalised. The bytes go over the socket (`file.attach`), the agent's new `attach_file` control copies them under their own name into the session's readable artifact directory (the same place accepted image originals go) and answers with a number, and a `[File #N]` chip lands in the draft beside a file card (name, extension, size). The draft is the truth: a chip deleted at submit un-attaches, as it does for images. At submit `_drain_pending_files` appends one block per file after the prompt — a header the clients recognise, then the contents of a text file or a Read-tool hint for a binary one, classified the way an `@path` mention is (`read_file_attachment`, shared with that pipeline). Text over 256 KB is pointed at rather than inlined; files are capped at 10 MB, refused before the upload on the client and before the decode on the gateway; eight pending files at most, as for images. A reopened conversation turns the blocks back into file cards and keeps the inlined contents out of the caption.

The end-anchored "+500k" turn-budget shorthand and the UserPromptSubmit hooks read the prompt through _extract_prompt_text, which joins every text block with no separator — so the file block the drain appends welded "+500k" to "[File #1: …" and silently no-op'd the budget, and hooks were handed up to 256 KB of file contents as "the prompt" (the resized-image metadata block had the same latent effect). They now read the first text block, which is what the user typed. Also: Windows reserved device names and Unicode format characters are neutralised in stored names; a large text file is pointed at without being read whole; a literal closing tag inside inlined contents can no longer end the envelope early; a file dropped at submit, on /clear or on resume takes its persisted copy with it, and losing the pending-cap race removes the whole copy folder; a relative path resolves against the session directory; the composer shows the name the backend kept; a dropped folder is skipped with a notice instead of being uploaded as an empty file; a paste with files on the clipboard attaches them uniformly; the stored header regex tolerates any name and path shape short of a newline. The text fixture is written as bytes so its size holds on Windows.

the file drain runs off the loop Follow-ups from the approving review: a session's shutdown discards the copies of files attached for a draft that will never be sent, as /clear and resume already did; the file drain's reads and decodes run in a thread so a slow disk cannot stall the other sessions on a multi-session transport; stored names also lose C1 controls and line separators; any spelling of the closing reminder tag is neutralised; an upload that lands after more typing inserts its chip into the current draft, not the one it started from; a dropped folder is told apart by its entry (Linux gives a folder the inode's size) and the notice says what is skipped; a user's own first block can never be read as a file block on reopen.
