What this is

A DSH plugin for dsh-tui only. It does not list sessions and it does not replace /resume.

pi-tui and the web profile are not supported.

On DSH it:

• /nix — deletes the current session, starts a new one, and switches the live view to it
• /nix quit — deletes the current session and exits DSH

Deletion is the whole session directory (and sidecar), not a single session.jsonl.zstd. After dsh-tui has switched away, the previous session is stopped/flushed/detached, the directory goes to Trash on macOS (rm -rf elsewhere), then projection cache and workspace accounting are cleared.

dsh-tui's /new and /resume delete keep the previous log. /nix is the destructive counterpart.

Installation

dsh plugin --profile dsh-tui add dsh-session-cleanup

From this repo:

npm run build
dsh plugin --profile dsh-tui add file:$PWD

Restart the profile. Confirm it loaded:

dsh --profile dsh-tui --dump-config | grep session-cleanup
dsh --profile dsh-tui

Commands

Command	Arguments	Description
/nix	—	Delete the current session, start a new one, switch the live view
/nix quit	—	Delete the current session and exit DSH
/nix help	—	Usage

Both destructive commands ask for confirmation when userQuestions is mounted (dsh-tui does).

/nix needs dsh-tui's scene switch (channel.newSession()). On any other profile it refuses rather than leaving you on a deleted conversation. Use /nix quit to delete and exit.

Safety

1. Confirm before delete
2. Switch first — /nix starts and adopts the new session before the old directory is removed
3. macOS Trash for session directories; other platforms permanently remove them
4. Cleanup order — disk/log removal is confirmed before workspace accounting is stripped
5. Both id spellings — <uuid> and session-<uuid>

Development

npm run build    # emit lib/dsh-entry.js for DSH
npm run test     # test suite
npm run check    # build + test

Native DSH entry: dsh-entry.ts → lib/dsh-entry.js.

Attribution

The /nix idea comes from pi-session-cleanup (MIT © MasuRii). The DSH port uses DeepSeek Harness persistence, workspace accounting, and dsh-tui's live session switch.
