@mi-lu-uncle/dsh-session-delete

English | 简体中文 | 日本語

Adds a Delete session action to the session "…" menu of DeepSeek Harness (DSH).

DSH 0.2.0-rc.2 only ships archive (a soft delete: hidden, but all data is kept). This plugin fills the gap — one click permanently deletes a session together with its on-disk data.

Features

• In the session row's "…" menu, right after the built-in Pin / Rename / Fork / Archive, a new Delete session entry appears.
• Clicking it opens a confirmation dialog (showing the session title); confirming invokes the host-side delete.
• Deleting cleans up three data locations:
  1. The session itself: ~/.dsh/sessions/<workspace>/<session-id>/
  2. The projection cache: ~/.dsh/storages/session_projcache/sessions/<session-id>.json
  3. The session's registration in the workspace index (sessionIds / archive / pin marks)
• After a successful delete, the open UI needs no refresh — the row disappears via the api-session/removed event.
• Auto-repairs the default workspace: DSH's built-in "Delete workspace", if it ever deleted the default one, leaves dangling pointers — its sessions fall into "Ungrouped" and new sessions can no longer be created. On startup this plugin rebuilds the registration and re-homes the sessions for the default workspace only (identified via defaultWorkspaceId or the last remembered path). Other workspaces you deleted on purpose are not "revived".

Safety

• Running sessions refuse deletion: it uses the same workspace/session-activity detection as DSH's archive. Only genuinely running work (an in-flight conversation turn, background jobs, …) is blocked with "this session is running"; idle old sessions (even if still kept alive in DSH's memory) delete normally.
• Deletion goes through DSH's own workspace-registry write paths (detachSession / unarchiveSession / unpinSession), so persisted state stays consistent.
• Routes are same-origin fenced; only requests coming from the DSH UI itself are accepted.

Install

This plugin targets DSH 0.2.0-rc.2 and is linked into the desktop profile as a local directory:

dsh plugin --profile desktop add "link:/absolute/path/dsh-session-delete"

Then restart DSH for it to take effect.

You can also edit ~/.dsh/profiles/desktop/package.json manually:

{
  "dependencies": {
    "@mi-lu-uncle/dsh-session-delete": "link:/absolute/path/dsh-session-delete"
  },
  "dsh": {
    "profile": {
      "bundles": [
        // ... existing ...
        "@mi-lu-uncle/dsh-session-delete"
      ]
    }
  }
}

Then run pnpm install in the profile directory and restart DSH.

Usage

1. In the session list on the left, hover a session and click its "…".
2. Choose Delete session.
3. Click Delete in the confirmation dialog.

⚠️ Deletion is permanent and irreversible. Make sure the session really is no longer needed.

Limitations / notes

• This is a community plugin built on DSH's public extension points (the session-menu slot sidebar.workspaces.session.menu.item plus host-side file/registry cleanup). If a future DSH release ships an official "delete session" API, prefer that.
• Running sessions refuse deletion; if you really need one gone, stop it first (finish/archive its work) and then delete.
• The full-text search index is a rebuildable read model of DSH's; right after a delete there may be briefly stale results until the next rebuild.
