Feature Request: Support native /delete command to permanently delete sessions

Feature Request: Native /delete command for sessions

Currently DeepSeek Harness only supports archiving sessions (e.g. the archive action in the workspace/sidebar). There is no built-in way to permanently delete a session.

Proposal

• Add a native /delete command (and/or a delete action in the session sidebar/workspace).
• It should permanently delete the session record/files, with a confirmation step to prevent accidental deletion.
• Ideally it should also stop or handle running agents before deletion.

Use case

Users often create many temporary/experimental sessions and need to clean them up completely, not just hide them via archive.

Thanks for considering this!

Just to add a status note: I've already built this end-to-end on my fork and verified it.

• RPC workspace.deleteSession (+ session/deleted event, host/session-removed frame)
• SessionPersistence.delete(id): JSONL removes $DSH_HOME/sessions/<ws>/session-<id>/ (frees disk); SQLite deletes the row (FK cascade)
• close-then-delete: disposes the live agent via AgentRegistry.dispose(id) so idle sessions are deletable; session-live only as a re-entry race fallback
• registry/archive/feedback cleaned in one pass; message-feedback sidecars cascade on session/deleted
• Tests: rebased onto latest master, relevant tests green + typecheck; added SQLite storage-level delete coverage (row + FK cascade)

Branch: feat/session-delete @ https://github.com/ywleeo/deepseek-harness/tree/feat/session-delete
Per the repo's current note (no external PRs accepted for now), I didn't open a PR. Happy to have the team merge the branch directly if scheduled; open to review/testing feedback.

Hey everyone!
I ran into an issue with DeepSeek Harness (DSH) and wanted to share how I fixed it. Hopefully this helps others facing the same problem!

The Problem
I deleted a workspace, but all my chat sessions didn't get deleted. They ended up in a section called "Ungrouped" with no obvious way to delete them. The "Archive" button just hides sessions -it doesn't actually delete them from disk.
Here's what it looked like:
text

• Workspace (deleted)
  └── Sessions moved to "Ungrouped"
  ├── Chat session 1 (can't delete)
  ├── Chat session 2 (can't delete)
  └── Chat session 3 (can't delete)

The Solution
I found a community plugin called dsh-plugin-session-delete by lsz-asd (GitHub). It adds a proper "Delete" button to sessions, including those in "Ungrouped".
The plugin is available here: https://github.com/lsz-asd/dsh-plugin-session-delete
Important: The latest version (v0.3.1) specifically fixes the "Ungrouped" issue where deleted sessions would reappear. Make sure you're using this version!
