dsh-session-recycle-tools

Adds two entries to the DeepSeek Harness web sidebar, stacked above the settings row at the bottom left:

  ☑  Batch delete            <- this plugin
  🗑  Recycle bin            <- this plugin
  ⚙  Settings                <- the host's own row

The recycle bin is its own list, not the host archive

The sidebar's built-in archive writes workspaces.archivedSessionIds and shares one "archived" view. This plugin does not touch it: the two coexist and neither knows about the other.

	Host archive	This recycle bin
Recorded in	archivedSessionIds in the workspace record	the plugin's own list in localStorage (dsh-session-tools.trash.v1)
Hiding	the host filters the row	the plugin wraps uiWorkspace.isSessionVisible; only ids in its own list return false
Restore	unarchive through the host	delete the id from the list; the session is back immediately
Relationship	unaware of the recycle bin	calls the host's original filter unchanged, then intersects it with its own set

How client.js does it:

1. apply() resolves ctx.get('uiWorkspace') and replaces isSessionVisible with (id) => trash.has(id) ? false : original(id), restoring the original in the ctx.effect cleanup. Whatever the host already filtered (a workbench session filter, for example) still runs through original(id) with the same meaning.
2. After the list changes, uiWorkspace.sessionVisibility is bumped so the sidebar tree recomputes its rows.
3. Moving a session sends no archive request. Permanently delete is the only path that calls the host's uiWorkspace.deleteSession(), the same path as "permanently delete session" in the session context menu.
4. A session that is currently running is refused: it would otherwise vanish from the list while still working in the background. The dialog says so instead.
5. An id that disappears from the session list entirely is pruned from the bin after a 60-second grace period.

Known cost: the list lives in the browser's localStorage for the current origin (http://127.0.0.1:<port>). Clearing site data or switching ports empties the recycle bin; the only consequence is that those sessions reappear in the list, and no content is lost.

Layout

The host half is a single loader row whose only job is to let dsh-client-modules see this package's dsh.client declaration and serve client.js to the page. The plugin registers no host service, route, or tool, so the model cannot see it.

.
|- package.json           # dsh.bundle.patch + dsh.client { platform: 'web' }
|- cordis.patch.yml       # one insert line: - id: dsh-session-recycle-tools
|- lib/index.js           # host half: an empty apply()
|- client.js              # the two buttons and the two dialogs
|- screenshots.json       # 1-8 storefront screenshots
|- assets/icon-180.png    # 180x180 storefront tile

Host capabilities client.js relies on:

Purpose	Source
Session summaries	ctx.get('sessions').list (ids / byId, including running)
Workspace grouping	ctx.get('workspaces').list (items[].sessionIds)
Hide and restore	wrap uiWorkspace.isSessionVisible and bump uiWorkspace.sessionVisibility
Permanent delete	uiWorkspace.deleteSession()
The recycle-bin list	the plugin's own localStorage key
Registration	sidebar.footer.action (a list slot, one row above sidebar.settings); dialogs use shell.overlay
Icons, buttons, checkboxes, dialog	@deepseek-ai/dsh-client-ui-primitives

The two dialogs

Entry	Dialog	What it does
Batch delete	every session, grouped by workspace, with a search box	check sessions (whole group or all), then move them into the recycle bin, which is the only action here
Recycle bin	sessions in the list, grouped by workspace, newest first	restore one or all; permanently delete one or empty the bin

Both dialogs are 1240px wide and follow the application body text: 20px title, 16px description, 16px session title, 14px timestamps and paths, 15px buttons.

Install

dsh plugin --profile web add github:4wgtty4zm7-a11y/dsh-session-recycle-tools

Then restart the running DSH web service. No host tool, route, or configuration is added.

Compatibility

Requires a DSH build that serves client plugins through dsh-client-modules and exposes uiWorkspace with isSessionVisible, sessionVisibility, and deleteSession. If isSessionVisible is missing, the plugin still records the list and says so in the dialog rather than hiding anything silently.
