feat(web): save files from chat and the file panel to your machine - #33827
When an agent creates a file on the server (for example reports/sales-q3.csv), I can open it in T3 Code but cannot copy it to the machine I'm viewing from. "Save file" exists only for attachments, large text files, and binary/document previews. A regular text file, image, HTML, or PDF opened in the file panel has no way to save it, and a file chip in chat has none either.
Repro: ask an agent to create a small CSV and link it. Right-click the chip in chat (no save option), then open it in the file panel (no Save button).
Change
Adds the existing "Save file" action to the two places it was missing:
Chat file chip: right-click → Save file. A bare link like report.csv resolves to the matched workspace file first, using the same resolveHostPath() as Open/Reveal.
File panel toolbar: a Save file button, shown only when the rendered preview has no Save button of its own, so it never duplicates the large-text or attachment one.
Both go through the existing media-file asset URL with disposition: "attachment", which main already serves as application/octet-stream. There is no server or contract change. Desktop shows the native Save dialog; web follows the browser's download settings; remote and tunnel connections work because the bytes come through the environment's signed asset URL. Gated on the filesystem read scope, like the previews. Not added to mobile.
Scope and approval
No prior discussion. I believe this falls under extending an established capability: "Save file" already ships for attachments (AttachmentFilePreview) and large workspace text files (WorkspaceLargeTextPreview), and it uses the same asset route. This PR closes the gap so the same action is available wherever a host file is shown. It adds no setting, default, or workflow. If you'd rather see an Ideas discussion first, I'm happy to open one.
Verification
vp test run apps/web/src/components/files/FilePreviewPanel.test.ts: 32 passed. Typecheck and lint clean for apps/web.
Manual check in the web dev build on d49d8b3: an agent created reports/sales-q3.csv (283 bytes). Right-click on the chat chip → Save file, and the panel toolbar Save file button. Both produced a 283-byte sales-q3.csv download and a "Download started" toast.
Not checked: the desktop native Save dialog, and the bare-basename resolution in chat (it reuses resolveHostPath(), already used by Open/Reveal).
Before / after
Before: no Save in the chip menu, no Save button in the panel.
After: Save file in the chip menu, download button in the panel toolbar.

Macroscope's review found this PR approvable — Adds user-triggered file downloads using existing authorized asset-serving mechanisms without changing preview defaults. The reported chat-link path issue remains subject to the separate correctness blocking gate.

Files an agent creates on the server could be previewed but not copied to
the viewing device. Add "Save file" to the chat file chip menu and to the
file panel toolbar, for files that had no Save button yet. It downloads
through the existing attachment-disposition asset URL, so desktop shows the
native Save dialog and remote connections work.

It looks like this branch is under active development. To avoid overwhelming you with review comments due to an influx of new commits, CodeRabbit has automatically paused this review. You can configure this behavior by changing the reviews.auto_review.auto_pause_after_reviewed_commits setting.
The change adds a shared hook that downloads files through an environment connection. Chat file links and the file preview panel now offer Save file actions when their respective conditions are met.
Changes: Save As downloads
Layer / File(s)
Summary
Save As download execution apps/web/src/components/files/useSaveFileAs.ts
The hook creates and resolves an attachment URL, downloads the file using its path-derived filename, and reports progress or errors with toasts.
Chat and preview actions apps/web/src/components/ChatMarkdown.tsx, apps/web/src/components/chat/MarkdownFileLink.tsx, apps/web/src/components/files/FilePreviewPanel.tsx, apps/web/src/components/ChatMarkdown.permissions.browser.test.tsx
Chat file links show a Save file action when a thread exists, filesystem-read scope is available, and the path is not an app bundle or directory. The preview panel shows the action for eligible non-draft files when the preview does not provide its own save control. The permission test expects the save action before and after host-action permission revocation.

Handle failures before they become unhandled rejections.
The call site uses void saveMarkdownFileAs(...). resolveMarkdownFilePath awaits findWorkspaceBasenameMatch, which awaits searchProjectEntries. saveFileAs catches its own errors. The path lookup before it is not covered. A thrown error there becomes an unhandled promise rejection and the user sees no feedback.
Wrap the path resolution in the try scope, or catch it and show an error toast.

@coderabbitai The outside-diff finding (unhandled rejection in saveMarkdownFileAs) applies to b06467c811, which the rebase replaced. saveMarkdownFileAs no longer exists. In d49d8b3ab7 the chat passes the path lookup to useSaveFileAs as a function (path: async () => (await resolveHostPath()).absolutePath), and the hook awaits it inside its try. A failed lookup now shows the "Could not save file" toast instead of rejecting.
For best results, initiate chat on the files or code changes.

@0xtlt Thanks for the clarification. I verified revision d49d8b3ab7: useSaveFileAs awaits the path lookup inside its try and catches a failure to show the “Could not save file” toast.
The unhandled-rejection finding no longer applies to the current revision.
If you found this review helpful, would you consider giving us a shout-out on X?
…ermissions
React Compiler skips hooks that throw inside try/catch, so the download
steps move to a plain async function. The chat permissions test now expects
Save file, which needs only read access and stays after host revocation.

- Around line 27-57: Update useSaveFileAs to move the save operation into a
module-level async helper that returns a success or error result instead of
throwing; handle rejected input.path() and downloadMedia promises through that
result as well. Keep the hook body responsible only for updating the success or

hook’s compilation path.

Merged current main (merge commit, no rebase). One conflict in ChatMarkdown.tsx: kept both the canReadFiles/useSaveFileAs lines and main's isClientHost line.
Hid chat Save for macOS .app chips (!isAppBundle) and for directory links ending in / or \. Both are directories, so the attachment request can only fail.
Earlier findings (Macroscope chip path, CodeRabbit hook compilability and permission test) were already fixed in 28c92937d0.
Not changed: CodeRabbit's "keep Save on the selected environment". The Electron local-media fallback lives in shared createAssetEnvironmentAtoms and already applies to the file panel's existing attachment download on main; changing it is outside this PR.
vp run check:changed passes on the head: format, lint, knip, typecheck, 4 test files (59 tests), react compiler.

Keep Save on the selected environment
If a remote image is missing and a different file exists at the same path on the primary environment, the media fallback can download the local file without warning. Make this Save request use only the selected environment. Preserve the fallback for media previews.

Hide Save file for directory links.
For a link such as patches/, Save requests a directory as a media-file attachment. The asset request fails because it accepts only files. Exclude trailing separators, but preserve POSIX filenames that end in a literal backslash.
