What this is

This is a DSH plugin, verified on the pi-tui and dsh-tui profiles. It is inspired by MasuRii's Pi extension, but it is not a drop-in Pi package.

On DSH it:

• lists sessions with sessionPersistence.listSnapshots() + locate()
• deletes through the host cleanup chain: stop / flush / detach, then the session directory, projection cache, workspace accounting, and pi2dsh sidecar
• sends the session directory to Trash on macOS, and uses rm -rf on other platforms

Deletion is the whole session directory (and sidecar), not a single session.jsonl.zstd. The leftover Pi trash/unlink path refuses those DSH artifacts so it cannot leave a hole in persistence.

Supported TUIs

Profile	Package	Notes
pi-tui	dsh-pi-tui	Original verification target
dsh-tui	@deepseek-harness-tui/dsh-tui	Claude Code-style TUI; /nix quit covers delete-current-and-exit, which that TUI does not do itself

The web profile is not a target. It already has a dedicated session-delete plugin.

Installation

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

From this repo, or a local checkout, the package must ship compiled JS (lib/dsh-entry.js):

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

Restart the profile. Confirm it loaded:

dsh --profile pi-tui --dump-config | grep session-cleanup
dsh --profile dsh-tui --dump-config | grep session-cleanup
dsh --profile pi-tui    # or: dsh --profile dsh-tui

Commands

Command	Arguments	Description
/session-cleanup	—	List orphaned sessions (cwd directory is gone)
/session-cleanup orphaned	—	Same as default
/session-cleanup current	—	Sessions from the current working directory
/session-cleanup all	—	All persisted sessions
/session-cleanup delete	<id...>	Delete those session ids after confirmation
/session-cleanup help	—	Usage
/nix	—	Create a new DSH session, then delete the current one
/nix agent	[preset]	Same, with a selected or named agent preset
/nix quit	—	Delete the current session and exit DSH
/nix help	—	/nix usage

With a userQuestions service (both pi-tui and dsh-tui mount one), /session-cleanup opens a multi-select + confirm flow. Without one, it prints the list and you delete by id.

TUI / menus show the argument grammar in the command description. After-space completions (orphaned, quit, …) need a host-side argumentHint hook and are not wired yet.

/nix on DSH

/nix is destructive and asks for confirmation.

• /nix creates a new session with ctx.agents.create (or ctx.sessions.create) using the current cwd and preset, then deletes the previous session.
• /nix agent [preset] does the same with a DSH agent preset. Without [preset], it opens a picker.
• /nix quit deletes the current session, disposes the root fiber, and process.exit(0).

DSH has no host-level “current session pointer”. After /nix, the TUI may keep showing the old conversation until you resume the new id:

dsh --profile pi-tui --resume <new-id>
dsh --profile dsh-tui --resume <new-id>

Safety

1. Active session excluded from the cleanup list
2. Confirm before delete
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. That graph does not import Pi packages.

Stock pi2dsh (remote main) is enough for this plugin. A patched pi2dsh is only needed if you load the leftover Pi extension path instead of the native DSH commands.

Attribution

Command names, scopes, and the /nix idea come from pi-session-cleanup (MIT © MasuRii). The DSH port uses DeepSeek Harness persistence, workspace accounting, and agent presets.
