dsh-delete-session

Delete sessions and manage archived sessions in the DeepSeek Harness (DSH) Web UI.

中文说明见 README.zh.md。

Adds Delete session to every session row's ⋯ menu (below Rename / Fork / Archive), plus a View archived sessions toolbar button that opens a DSH-native window for restoring or permanently deleting archived sessions.

Screenshots

Quick start

dsh plugin --profile web add github:Da-Mie/dsh-delete-session

Restart DSH and refresh the Web UI. Every non-blank session's ⋯ menu now has Delete session, and the sidebar toolbar shows View archived sessions between View options and Add workspace.

Features

Delete a session (⋯ menu)

• Delete session item below Archive session in every non-blank session row's ⋯ menu, using the official trash icon.
• Shows a confirmation dialog before deleting.
• On confirm:
  1. cancels and waits for a running agent (if any);
  2. archives the session first so it disappears from the sidebar immediately;
  3. removes the session's persisted JSONL directory (permanent).
• Best-effort refreshes the session/workspace lists so cold sessions also leave search/list right away.

Archived sessions manager (toolbar)

• View archived sessions button between View options and Add workspace, using the official archive icon.
• Opens a DSH-native modal (the official Modal primitive) listing every archived session: title, workspace, working directory, and last-update time.
• Restore — returns the session to the workspace it was archived from; all timestamps and the session's files are kept, because archiving never touches workspace accounting or the session log.
• Delete permanently — two-step confirmation, then removes the session's persisted log and drops it from the archive set.

Requirements

• DeepSeek Harness ≥ 0.1.0-rc.5 (Web UI profile; check with dsh --version)

Installation

The package ships prebuilt (lib/ is committed), so no build step is needed.

Install with DSH (AI)

Just hand this repository URL to your DSH agent:

https://github.com/Da-Mie/dsh-delete-session

DSH reads the repository's AGENTS.md and installs the plugin automatically.

From GitHub

dsh plugin --profile web add github:Da-Mie/dsh-delete-session

Or manually: link this directory into $DSH_HOME/profiles/node_modules/dsh-delete-session, register it in profiles/web/package.json under dependencies and dsh.profile.bundles, then restart DSH.

After installing, restart DSH (plugin-set changes take effect on restart), then refresh the Web UI.

How it works

• Host side — registers /dsh-delete-session <sessionId>, /dsh-archived-restore <sessionId> and /dsh-archived-delete <sessionId>. Delete cancels/waits for the agent, flushes the session, calls workspaceRegistry.archiveSession to hide it, then locates and removes the session directory via sessionPersistence.locate. Restore drops the id from the registry-global archive set — archiving never touches workspace accounting, so unarchiving restores the session's position, timestamps, and files.
• Client side — uses a MutationObserver to inject the Delete session menu item (cloned from the native Archive item) and the View archived sessions toolbar button (anchored to the stable View-options button, self-healing against React re-renders, with a CSS fix for the fixed-width header-actions row). The management window renders with the official Modal primitive through the shell.overlay slot.

Notes

• DSH's official session storage has no delete API; this plugin performs the documented out-of-band maintenance of removing the JSONL log directory. For live in-memory sessions it also best-effort detaches them from the session and agent registries so the log is not recreated by a later shutdown flush. If the internal detach fails, the session is still archived/hidden and residual logs may need manual cleanup.
• Deletion is permanent and cannot be undone.
• If no session context is available to run the host command (e.g. no opened session at all), the dialog reports that the command cannot run.
• If the log file is locked by a live session and removal fails, the session is still archived/hidden first and the command returns an error; the residual log may need manual cleanup.
