dsh-session-manager

dsh-session-manager gives the Harness Web UI a full session-management surface: browse all sessions and the archived ones, restore (unarchive) archived sessions back to their original workspace, archive any session, delete sessions with a two-step confirmation, and preview conversation content — all from the Settings panel, with zero modification to official packages.

What it solves

Stock DSH archives sessions one-way: the sidebar's Archive action hides a session from every view (workspace groups, ungrouped, search, flat list), and there is no view or API to bring it back — archived sessions are effectively lost until you hand-edit ~/.dsh/storages/workspace.json. This plugin makes archiving a reversible, manageable state and adds an overview of every session on disk:

right-click a session -> Archive (stock DSH)
  -> the session vanishes from the sidebar (nowhere to see it again)
  -> this plugin: Settings -> Session manager -> archived tab
       preview its content, Restore it (back to its original workspace
       position), or Delete it from disk (two-step confirmation)
  -> the all-sessions tab lists every persisted session (grouped by
     workspace, ungrouped ones included) so nothing is ever lost sight of

Features

Restore archived sessions: an archived session keeps its workspace accounting slot, so unarchiving puts it back exactly where it was — single, batch, or all at once.
Delete with two-step confirmation: the Delete button arms first and needs a second click within 5 seconds; sessions whose agent is running are rejected server-side.
Delete all: clears every deletable session (archived, ungrouped, and workspace-attached alike) in one confirmed action, skipping sessions that are currently running or open, and reports per-session success / failure / skip.
All-sessions overview: every session known to the persistence layer — title, id, creation time, owning workspace (or *ungrouped*), status badges (archived / live / running) — with archive and delete actions.
Content preview: click a session title to expand the first 100 user / assistant / tool messages without opening the conversation.
Disk footprint: per-session size and the full on-disk path help you find what is eating space.
Zero core modification: a pure bundle plugin (dsh.bundle patch layer); every operation goes through official services (workspaceRegistry, sessionPersistence, sessionQuery, fs, shell, …) — no official package is patched or overridden.
Loopback-only API: the /dsh-sm/* routes reject non-loopback hosts and cross-origin requests (Host + Origin / Sec-Fetch-Site fence).

Installation

# one line, from a git source
dsh plugin --profile web add github:omdsh-dev/dsh-session-manager

# restart the web server, then hard-refresh the page

Local development:

dsh plugin --profile web add /path/to/dsh-session-manager

The repository ships plain-JS lib/ artifacts with no build step, so git-source installs work without any build tooling on the user's machine.

Usage

Web UI

Session manager (settings page)

Open Settings → Session manager:

Archived tab (default): every archived session with title, id, creation time, cwd, disk size and the full on-disk path; status badges for *running* and *missing files*. Buttons: Restore (single / batch / all), Clear archive (delete all archived, two-step), row-level Delete (two-step).
All sessions tab: every persisted session grouped by workspace (ungrouped sessions show a —), status badges for *archived / live / running*. Actions: Archive, Delete, and Delete all (two-step; skips running/open sessions).
Click any session title to preview its content inline (user / assistant / tool messages, first 100).

Architecture

lib/
├── index.js   Host half: cordis plugin (injects webServer) exposing POST /dsh-sm/* routes
└── client.js  Browser half: __ModuleLoader__ bundle registering the Settings section
cordis.patch.yml   dsh.bundle patch layer — one insert row drives both halves

browser (Settings page) --POST /dsh-sm/*--> host handlers
   archived/list · archived/unarchive · sessions/list · sessions/archive
   · sessions/delete · sessions/detail
   workspaceRegistry (archive-set read/write) + sessionPersistence (headers/locate)
   + sessionQuery (titles/content) + fs/shell (size/delete) + agents (running guard)

Host routes:

Route	Payload	Returns
`POST /dsh-sm/archived/list`	`{}`	`{ items, totalBytes }`
`POST /dsh-sm/archived/unarchive`	`{ sessionId }`	`{ ok, changed, archivedSessionIds }`
`POST /dsh-sm/sessions/list`	`{}`	`{ items }`
`POST /dsh-sm/sessions/archive`	`{ sessionId }`	`{ ok, archivedSessionIds }`
`POST /dsh-sm/sessions/delete`	`{ sessionId }`	`{ ok, deleted, sessionId, path?, reason? }`
`POST /dsh-sm/sessions/detail`	`{ sessionId }`	`{ id, createdAt, cwd, totalEvents, messageCount, truncated, messages }`

The unarchive path rewrites the durable archive set through workspaceRegistry.setState (with a workspace storage-domain fallback), so the registry's in-memory state and the on-disk global.archivedSessionIds stay consistent; the client refreshes the workspace/session stores afterwards so the sidebar updates immediately.

Testing

node test/smoke.mjs   # 10 host-logic checks against stub services

The smoke test drives apply(ctx) with stub services and covers the route wiring, the loopback/origin fence, archive-set read/write, delete bookkeeping and detail extraction. End-to-end verification was performed against a real profile (a second instance on a separate port plus a browser walkthrough of restore / archive / delete-all).

Roadmap

[x] Archived-session list / restore / delete (two-step)
[x] All-sessions overview + archive any session
[x] Delete all (skips running/open) with per-item results
[x] Inline content preview
[ ] Recycle bin (soft delete with undo window)
[ ] Sidebar entry in addition to the Settings page
[ ] npm release
