dsh-file-launcher

中文说明

A File launcher tab for the DeepSeek Harness right Sidebar. It answers one question in one place: which files did this conversation produce, deliver, read, or receive — and what can I do with them?

Features

• Conversation, Sent by me, project, pinned, and history scopes. Sent by me scans recent top-level conversations across every project and labels each file with its project and conversation; history is grouped into collapsible project sections.
• Durable Session-log inventory: present deliveries, write/edit/apply_patch results, read paths, user files, and normalized user images.
• Workspace document scan (Word, PowerPoint, Excel, PDF, Markdown, text, images, HTML, media, archives) with build-output filtering.
• One Filters control opens a master-detail panel: Source on the left is the parent (Delivered, User, Created, Read, Workspace…); Type on the right is nested under the selected source. Parent counts stay stable; child counts are computed inside the parent and also react to search and archived state. Active filters appear as removable tags; one Clear all action resets them.
• Sent by me and Project are grouped Project → Conversation with collapsible headers. Sent by me starts collapsed (configurable in Settings) so the panel opens on the project index; Project automatically expands when only the current workspace is present so files are visible without redundant clicks. Search or any active filter opens the groups automatically; filters apply inside each group and group counts update.
• Sent @paths are resolved: a file path becomes a User file; a folder path becomes a folder row with an Open in Explorer action; unknown/special extensions are classified (applications, design files, databases, fonts, disk images, binaries, folders).
• Live refresh while the panel is open: the active scope polls every 60 seconds by default (configurable between 5–300 seconds or off in Settings), reusing short-lived Host scan caches to avoid repeated log scans; an explicit Refresh bypasses caches (fresh=1). The Sent index merges the current conversation first.
• Missing files become ghost rows: a user/@ or delivered file that disappears is kept as an Missing row with its last path, instead of vanishing. Files deleted through the plugin are tombstoned and do not return. If a moved file reappears in the same conversation with the same name/size, the Sent index relinks it as Moved; a cross-drive move with no new reference cannot be discovered automatically, so the ghost remains until the new path is sent or the row is cleared.
• PDF/Office page preview has a persistent toolbar (previous/next, page count, zoom, fit width, open sidebar, close). Clicking outside does not close it; right-clicking the page opens the file menu.
• In-panel preview for images, PDF, Markdown, text, and Office documents. Images switch with previous/next buttons or ←/→; Word/PowerPoint/Excel are converted to PDF by the Host's office-kit, then rendered as page images.
• Always-visible row actions and a floating context menu: right-clicking (or clicking Open with) opens a scrollable menu at the pointer with preview, open/reveal, detected apps, copy, pin, archive, and Delete file.
• History has a global back button in the panel header after drilling into a project/conversation.
• Preview context menu: right-clicking an image preview offers copy-image, copy-path, reference, pin, archive, and delete.
• Delete with confirmation: permanently removes the file from disk after an explicit confirm; it also drops the pin and archive-manifest record. Use with care.
• Open with the detected desktop applications, show in file manager, or call the Windows system Open with dialog.
• Insert reference / Attach tries the optional fileDrag capability to attach the real file to the composer, and falls back smoothly to inserting a removable @path reference at the caret (or copying to the clipboard).
• Pin paths in a durable manifest outside the Session log, and recover them with the file_launcher tool after context compaction. Pins protect path memory only; files stay on disk.
• Archive copies into a dated folder under $DSH_FILE_LAUNCHER_ARCHIVE_DIR, your configured Custom archive folder in Settings, or ~/Documents/DeepSeekHarnessFileLauncher/Archived_Docs. The original is never moved or deleted, and archived copies get an Archived badge and filter.
• Agent tool file_launcher with list (including global sent), sessions, pin, unpin, and archive actions.

Install

The package is a DSH bundle. Add the package directory through Plugins → Add plugin (or install it with the plugin manager), then reload the page. The right Sidebar's + guide now offers File launcher.

Install from GitHub:

1. Open Plugins → Add plugin.
2. Choose the default / GitHub installation source (the mainland mirror is mainly for npm packages and may not proxy GitHub).
3. Enter https://github.com/ZOU2850/dsh-file-launcher.
4. Click Install.
5. Fully quit and reopen DSH after installation (1.4.x changes the Host scanning and settings modules).

If GitHub installation fails, use the local checkout path in the same field. Remove or disable any existing dsh-file-launcher install first to avoid a duplicate instance.

The Host half needs the Web profile's tools, fs, sessionQuery, connection, and attachments services. The browser half registers a page-type tab plus the header and composer quick entries, so no resource pattern or extra config is required.

Usage

1. Open the right Sidebar and choose the File launcher guide card (the + control in the tab strip), click the folder button in the conversation header's right-side utilities, or click the Files pill at the left of the composer tool row.
2. Pick a scope: Conversation, Sent by me, Project, Pinned, or History. In History, expand a project group and choose a conversation.
3. Click a row to preview in the panel; images and Office documents preview there with previous/next navigation. Use Open with for native applications, or Select for batch Insert reference, Pin, and Archive.
4. Right-click any row (or image preview) for the floating menu; Delete file asks for confirmation first.

Settings

Open Settings from the avatar menu; the File launcher section controls:

Appearance — theme (follow DSH / light / dark / follow system). Changing it applies immediately to an open Sidebar and saves to settings.json plus the browser-local cache for restarts and upgrades.

Behavior, preview, and paths — auto-refresh toggle and interval (5–300 s), default scope, collapsed-by-default groups, PDF page limit/DPI, rows per load, custom archive directory override, and the data/index/archive locations.

Preferences persist to $DSH_HOME/file-launcher/settings.json, outside the profile patch, so upgrades do not overwrite them.

Compatibility and upgrades

• Tested on DSH Desktop 0.2.2-rc.3 / Electron 44.7 / Node 24.21.
• Uses public extension points only (ctx.tools, ctx.connection.fetch, Cordis services, client slots/sidebarRightTabs/locale/remotes); it imports no @deepseek-ai/dsh-* package and lists optional capabilities (officeKit, fileDrag) without blocking startup.
• Settings register lazily through settings.section; on an older DSH without that slot the page is simply absent and the plugin still loads. A future change to that slot contract requires an update.
• Reinstall/re-enable the bundle, fully quit and reopen DSH, then refresh. Pins, sent index, archive manifest, settings, and deletion tombstones live under $DSH_HOME/file-launcher/ and survive upgrades.

Performance and resources

• No model tokens are consumed by the panel, previews, or auto-refresh. Only an explicit file_launcher tool call enters context (60 rows by default; lower it with limit).
• Auto-refresh defaults to 60 seconds, can be adjusted (5–300 s) or disabled in Settings, and aborts stale requests instead of stacking them.
• The panel loads at most 800 rows by default; PDF rendering defaults to 20 pages (maximum 40). Regular PDFs render directly from their Host path without base64 transfers.
• Memory is dominated by DSH/Chromium and any open page images; temporary preview links under $DSH_HOME/file-launcher/previews are pruned automatically.

Configuration

No plugin config is required. Optional environment variables:

Variable	Meaning
DSH_HOME	Harness home used for file-launcher/pins.json, archive.json, and image preview links (defaults to ~/.dsh).
DSH_FILE_LAUNCHER_ARCHIVE_DIR	Overrides the archive root.

Development notes

• Host: index.js, lib/inventory.js, lib/store.js, lib/routes.js, lib/tool.js.
• Browser: client.js (plain __ModuleLoader__ factory, React only).
• Locales: locale/en.json, locale/zh.json (Plugin Manager metadata); the panel dictionaries live in client.js.
• Icon: icon.svg.

Limitations

• Files created only by shell commands without a tool result or present declaration are attributed to the workspace, not the conversation.
• Native opening requires a Host desktop.
• Office in-panel preview depends on the profile's office-kit provider.
• PDF page rendering depends on local pdfinfo / pdftoppm; without them the preview shows an error and keeps Open in sidebar.
• A folder @path gets an Explorer entry; its contents are not expanded recursively.
• Sent by me reads up to 20 recent top-level conversations, sequentially and only on first access. The index is persisted in $DSH_HOME/file-launcher/sent-index.json (can be rebuilt on demand with Refresh); startup never prewarms it.
• Ghost rows cover user/@ and delivered files. Workspace-only files are discovered by directory scan; if one is deleted outside the plugin and was never referenced by the conversation, there is no historical path to keep as a ghost.
• Moved files cannot be found by magic. Cross-drive moves with no new message/reference keep the old ghost; relink needs the new path to reappear in a scanned session or a manual re-send.
• Live refresh is periodic polling (default 60 s). It is intentionally not a filesystem watcher; a just-created file appears on the next tick or via manual Refresh.
• Insert reference / Attach: uses the optional fileDrag service when available, falling back to @path text in the composer or clipboard.
• User @ references: a file the user sent as a plain-text @path (including absolute Desktop paths) is resolved and shown under User / Sent by me, not only browser file attachments.
• Delete file is permanent and cannot be undone; it is never triggered by archive or pin.
• Pins are host-global and not part of Session export; they protect path memory, never delete or move files.
• Archive copies are plain files with no version history; the original is kept.
• Normalized image attachments are extensionless; the Host publishes extension-bearing preview links under $DSH_HOME/file-launcher/previews while the attachment object remains the file of record.
