dsh-session-manager

In stock DeepSeek Harness, the sidebar Archive action is one-way: once a session is archived it vanishes from every view — workspace groups, flat list, search — and the only way to bring it back is hand-editing a local JSON file. dsh-session-manager turns that dead-end into a manageable state. From the Settings panel you can browse every session on disk (live and archived), restore archived sessions back to their exact original workspace one by one, in batches, or all at once, archive any session, delete with a two-step confirmation, and clear all deletable sessions in a single confirmed action that automatically skips sessions currently running or open.

Each row shows the session title, creation time, owning workspace (or ungrouped), status badges for archived / live / running, per-session disk size, and the full on-disk path. Clicking a title expands an inline preview of the first 100 user, assistant, and tool messages, so you can judge whether a conversation is still worth keeping without opening it. This is especially useful for long-running Harness users who have accumulated dozens of sessions across workspaces and want a quick way to audit, recover, or clean up disk space — no log digging, no config editing, everything handled from one panel.

Under the hood it is a pure bundle plugin: every operation goes through official services such as workspaceRegistry, sessionPersistence, and sessionQuery, so no official package is patched or overridden. API routes are restricted to loopback addresses and reject cross-origin requests, keeping the security boundary tight without adding a separate daemon.
